Abstract
The high volatility, water-immiscibility, and light/oxygen-sensitivity of most aroma compounds represent a challenge to their incorporation in liquid consumer products. Current encapsulation methods entail the use of petroleum-based materials, initiators, and crosslinkers as well as mixing, heating, and purification steps. Hence, more efficient and eco-friendly approaches to encapsulation must be sought. Herein, we propose a simple method by making use of a pre-formed amphiphilic polymer and employing the Hansen Solubility Parameters approach to determine which fragrances could be encapsulated by spontaneous coacervation in water. The coacervates do not precipitate as solids but they remain suspended as colloidally stable liquid microcapsules, as demonstrated by fluorescence correlation spectroscopy. The effective encapsulation of fragrance is proven through confocal Raman spectroscopy, while the structure of the capsules is investigated by means of cryo FIB/SEM, confocal laser scanning microscopy, and small-angle X-ray scattering.

Abstract
Over the past few decades, long acting injectable (LAI) depots of polylactide-co-glycolide (PLGA) or polylactic acid (PLA) based microspheres have been developed for controlled drug delivery to reduce dosing frequency and to improve the therapeutic effects. Biopharmaceuticals such as proteins and peptides are encapsulated in the microspheres to increase their bioavailability and provide a long release period (days or months) with constant drug plasma concentration. The biodegradable and biocompatible properties of PLGA/PLA polymers, including but not limited to molecular weight, end group, lactide to glycolide ratio, and minor manufacturing changes, could greatly affect the quality attributes of microsphere formulations such as release profile, size, encapsulation efficiency, and bioactivity of biopharmaceuticals. Besides, the encapsulated proteins/peptides are susceptible to harsh processing conditions associated with microsphere fabrication methods, including exposure to organic solvent, shear stress, and temperature fluctuations. The protein/peptide containing LAI microspheres in clinical use is typically prepared by double emulsion, coacervation, and spray drying techniques. The purpose of this review is to provide an overview of the formulation attributes and conventional manufacturing techniques of LAI microspheres that are currently in clinical use for protein/peptides. Furthermore, the physicochemical characteristics of the microsphere formulations are deliberated.

Abstract
Polyvinyl Alcohol (PVA) is a promising polymer due to its high solubility with water, availability in low molecular weight, having short polymer chain, and cost-effectiveness in processing. Printed technology is gaining popularity to utilize processible solution materials at low/room temperature. This work demonstrates the synthesis of PVA solution for 2.5% w/w, 4.5% w/w, 6.5% w/w, 8.5% w/w and 10.5% w/w aqueous solution was formulated. Then the properties of the ink, such as viscosity, contact angle, surface tension, and printability by inkjet and aerosol jet printing, were investigated. The wettability of the ink was investigated on flexible (Kapton) and non-flexible (Silicon) substrates. Both were identified as suitable substrates for all concentrations of PVA. Additionally, we have shown aerosol jet printing (AJP) and inkjet printing (IJP) can produce multi-layer PVA structures. Finally, we have demonstrated the use of PVA as sacrificial material for micro-electro-mechanical-system (MEMS) device fabrication. The dielectric constant of printed PVA is 168 at 100 kHz, which shows an excellent candidate material for printed or traditional transistor fabrication.

Abstract
The objectives of this study were to develop insect-resistant adhesives and apply them to a cardboard packaging system for preventing Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae) larvae infestation. Cinnamon essential oil (CO), an insecticide, was encapsulated with maltodextrin (CS/MD/CO), β-cyclodextrin (CS/β-CD/CO), and polyvinyl alcohol (CS/PVA/CO) in corn starch (CS) paste. This resulted in a sustained and gradual release of CO from the starch-based insect-proof adhesives. Penetration pathways of insects into corrugated cardboard boxes were investigated through the use of a screening test for infestation profiling. Microscopic images of encapsulated CO in an oil in water (O/W) emulsion were observed to confirm the morphology of the adhesives. Adhesion forces of CS, CS/CO, CS/MD/CO, CS/β-CD/CO, and CS/PVA/CO were determined to be 6.2 N, 4.0 N, 3.1 N, 6.0 N, and 5.8 N, respectively. Consequently, significant decreases of adhesion force in the CS/CO and CS/MD/CO were found to be due to the presence of the surfactant (Span® 80) and the low adhesive properties of MD. The duration of the insecticidal activities of the developed adhesives was evaluated by measuring their release rates for 14 days and repellent profiles up to 24 hr and 40 days. As a result, CS/β-CD/CO and CS/PVA/CO were found to have an inhibited rapid release and sustained repellent profiles. In conclusion, CS/β-CD/CO and CS/PVA/CO were determined to be suitable for encapsulation models and could be applied to industrial cardboard containers to prevent cases of insect invasion. PRACTICAL APPLICATION: Corn starch-based natural adhesives with an insect-proof property were applied to food containers consisted of corrugated cardboard boxes. Cornflake cereal packaging using insect-proof corrugated cardboard successfully prohibited pest invasion in commercial food distribution simulation model. Developed insecticidal adhesives are able to control insect penetration in distribution and storage steps.

Abstract
Photochromic materials have attracted considerable attention for their practical applications in optoelectronic devices. In this study, we developed the photochromic liquid core nanocapsules by polymerization of oil-in-water (O/W) nanoemulsion monomer droplets on the basis of Hansen solubility parameters. The thermoresponsive amphiphilic block copolymers (POEGMAm-b-PStn and POEGMAm-b-PMMAn) were synthesized by sequential reversible addition fragmentation chain transfer (RAFT) polymerization of hydrophilic oligo(ethylene glycol) methyl ether methacrylate and hydrophobic styrene or MMA. The O/W nanoemulsion methyl methacrylate (MMA) droplets, dissolving dipropylene glycol methyl-n-propyl ether (DPMNP) and (E)-3-(adamantan-2-ylidene)-4-[1-(2,5-dimethyl-3-furyl) ethylidene]dihydro-2,5furandione (Aberchrome 670) as a core liquid and a photochromic dye, respectively, were obtained through the phase inversion temperature emulsification technique using POEGMAm-b-PStn as a surfactant. As theoretically predicted in terms of the spreading coefficients, the DPMNP solution of Aberchrome 670 was successfully encapsulated by coacervation of the crosslinked PMMA condensed phase. Aberchrome 670 dissolved in a liquid core was found to photoisomerize twice as fast as that dispersed in the solid polymer matrices.

Abstract
Films containing microencapsulated cinnamon oil (CO) were developed using a large-scale production system to protect against the Indian meal moth (Plodia interpunctella). CO at concentrations of 0%, 0.8%, or 1.7% (w/w ink mixture) was microencapsulated with polyvinyl alcohol. The microencapsulated CO emulsion was mixed with ink (47% or 59%, w/w) and thinner (20% or 25%, w/w) and coated on polypropylene (PP) films. The PP film was then laminated with a low-density polyethylene (LDPE) film on the coated side. The film with microencapsulated CO at 1.7% repelled P. interpunctella most effectively. Microencapsulation did not negatively affect insect repelling activity. The release rate of cinnamaldehyde, an active repellent, was lower when CO was microencapsulated than that in the absence of microencapsulation. Thermogravimetric analysis exhibited that microencapsulation prevented the volatilization of CO. The tensile strength, percentage elongation at break, elastic modulus, and water vapor permeability of the films indicated that microencapsulation did not affect the tensile and moisture barrier properties (P > 0.05). The results of this study suggest that effective films for the prevention of Indian meal moth invasion can be produced by the microencapsulation of CO using a large-scale film production system. PRACTICAL APPLICATION Low-density polyethylene-laminated polypropylene films printed with ink incorporating microencapsulated cinnamon oil using a large-scale film production system effectively repelled Indian meal moth larvae. Without altering the tensile and moisture barrier properties of the film, microencapsulation resulted in the release of an active repellent for extended periods with a high thermal stability of cinnamon oil, enabling commercial film production at high temperatures. This anti-insect film system may have applications to other food-packaging films that use the same ink-printing platform.

Abstract
Time release of encapsulated vinylene carbonate (VC) from microcapsules in Li-ion batteries is demonstrated to enhance the rate performance without sacrificing capacity retention. VC-filled microcapsules are successfully prepared by the solvent exchange method that allows VC to diffuse through the microcapsule shell wall at an elevated temperature. The concentration of VC added directly to the electrolyte in a pouch cell (2 wt %) significantly decreases after the first cycle at C/10-rate. In pouch cells that contain 5 wt % VC-filled microcapsules, the concentration of VC increases from 0 to 3 wt % over the first cycle because of the diffusion of microencapsulated VC in the electrolyte. Electrochemical impedance spectroscopy, rate capability, and long-term cycling tests are conducted for pouch cells with VC additives (0, 2, and 5 wt %) and VC microcapsules (5 wt %). Pouch cells with both 5 wt % VC additive and microencapsulated VC show improved capacity retention over 400 cycles at 1 C-rate compared to the cells without VC additive. When VC is added directly, the high initial concentration leads to increased interfacial resistance and decreased rate capability. By contrast, time release of microencapsulated VC by diffusion through microcapsules increases the discharge capacity 2.5 times at 5 C-rate compared to the direct VC addition to the electrolyte.

Abstract
The purpose of this study was to develop acaricidal cotton fabrics grafted with eucalyptus oil-loaded microcapsules (EOMCs) produced from green resources. EOMCs showed a broad size distribution between 0.5 and 6.5 μm, and had the average diameter 1.8 μm. EOMCs exhibited nonporous spherical shapes and individually remained on cotton fibres. Through AATCC mortality tests against house dust mites (HDMs) (Dermatophagoides farinae), the treated cotton fabric containing EOMCs resulted in 98.7% mortality. Acaricidal efficiency was due to the large amount of oxygenated monoterpene, 1,8-eucalyptol (75.8%) and hydroxylated monoterpenes such as α-terpineol (3.6%), terpinen-4-ol (0.4%) and linalool (0.3%) found in eucalyptus oil. These compounds are effective in enhancing penetration into HDMs. EOMCs produced from safe and natural sources can serve as a replacement for synthetic acaricides in controlling the population of HDM, leading to positive impacts on the human health and environment.

Abstract
We here demonstrated a general, convenient, and robust method to fabricate the hybrid microcapsules through the one-step thiol-ene photopolymerization at the interface between toluene and water. In the presence of amphiphilic polyhedral oligomeric silsesquioxane (POSS) containing thiol groups (PTPS) as reactive surfactants and trimethylolpropane triacrylate (TMPTA) as a cross-linker, the wall of hybrid microcapsules can be photo-cross-linked. The obtained hybrid microcapsules (HMCs) were well-characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), and confocal laser scanning microscopy (CLSM). The results revealed that the obtained HMCs are uniform with the tunable size in diameter (2-4 μm) and wall thickness (55-120 nm). The size of HMCs increased with the increasing content of toluene. The wall thickness of HMCs decreased with the increasing content of toluene, while the wall thickness of HMCs increased with the increasing content of cross-linker TMPTA. Furthermore, HMCs are thermoresponsive in aqueous solution, can encapsulate both hydrophobic and dydrophilic dyes, and can be used in the controlled dispersion of dyes in different mediums. It is believed that this simple, robust, and general method to fabricate the hybrid microcapsules will extend the potential application fields of microcapsules, such as in the controlled dispersion and drug delivery.

Morphology, Stability, and Application of Lycopene Microcapsules Produced by Complex Coacervation. J CHEM-NY 2013.

Abstract
The interest in lycopene has increased in recent years due to studies that associate it with the reduction in risk of developing cardiovascular diseases and cancer. However, due to its high degree of unsaturation, this carotenoid is inclined to isomerize and oxidize during processing and storage, making it difficult to use in the food industry. Microencapsulation can improve this situation, increasing its stability and making incorporation into food formulations possible. Thus, the aim of this study was to microencapsulate lycopene by complex coacervation using gelatin and gum Arabic as the encapsulating agents. The microcapsules were evaluated based on the encapsulation efficiency and their morphology and then submitted to a stability test and applied in cake making. Most of the systems studied presented spherical microcapsules with defined walls. The encapsulation efficiency values were above 90%, and the average diameter of the capsules ranged from 61 to 144 μm. The stability test showed that microencapsulation offered greater protection to the lycopene as compared to its free form. The application of nonfreeze dried coacervated microcapsules in cake making was satisfactory, but the color transference was low when freezedried coacervated microcapsules were used.

Abstract
In the world, approximately 600,000 metric tonnes of chromium-containing solid wastes are generated by the leather industry each year. Environmental concerns and escalating landfill costs are becoming increasingly serious problems to the leather industry and seeking solutions to these problems is a prime concern in much research today. In this study, solid collagen-based protein hydrolysate was isolated from chromium-tanned leather wastes and its chemical properties were determined. Microcapsules of collagen hydrolysate (CH) - chitosan (C) crosslinked with glutaraldehyde (GA) containing Lavender oil (LO) were prepared by complex coacervation method. The effects of various processing parameters, including the CH to C ratio, LO content, and GA, on the oil load (%), oil content (%), encapsulation efficiency (%) and release rate of LO from microcapsules were investigated. As the ratio of C present in the CH/C mixture and crosslinking density increased, the release rate of LO from microcapsules slowed down. Optical and scanning electron microscopy images illustrated that the LO microcapsules were spherical in shape. Fourier transform infrared spectroscopy (FTIR) studies confirmed that there was no significant interaction between CH/C complex and LO.

Abstract
O objetivo desta revisão é abordar as aplicações de nanotecnologia em alimentos, enfatizando o uso de nanopartículas lipídicas sólidas, nanoemulsões, nanocápsulas e de nanocompósitos para embalagens de alimentos, bem como os métodos de obtenção, a funcionalidade e as suas características. A aplicação da nanotecnologia em alimentos é nova em comparação com a área biomédica e as indústrias de tecnologia de informação, nas quais a nanotecnologia já é utilizada na fabricação de materiais. No entanto, já existem inúmeras oportunidades que podem ser exploradas, como a elaboração de produtos com características funcionais e nutracêuticas, o desenvolvimento de processos e as embalagens inteligentes. Esta revisão aborda os seguintes itens: nanopartículas lipídicas sólidas, nanoemulsões, nanocápsulas, nanocompósitos em embalagem e os riscos e a legislação para a nanotecnologia. Nanopartículas lipídicas sólidas são sistemas de transporte coloidal empregados para encapsular, proteger e entregar componentes funcionais. Nanoemulsão consiste em uma dispersão muito fina composta por uma fase de óleo e uma fase aquosa, com tamanho de gota, em escala nanométrica; em função do seu tamanho característico, as nanoemulsões são transparentes ou translúcidas, e possuem estabilidade contra a sedimentação. Nanocápsulas são compostas por um invólucro polimérico disposto ao redor de um núcleo, no qual se encontra o composto ativo, conferindo proteção contra o oxigênio, a água e/ou a luz; permitem, dessa forma, uma liberação controlada da substância e/ou previnem o contato com outros componentes em uma mistura. Em nanotecnologia de embalagens, aborda-se a utilização de nanopartículas, tais como nanofibras de celulose e nanoargila, bem como a aplicação de nanomateriais com propriedades nutricionais e/ou antimicrobianas, e nanosensores. Serão abordados também aspectos relacionados aos riscos e à legislação em nanotecnologia de alimentos.

Abstract
The processing parameters of pump speed, inlet air temperature, outlet air temperature and homogenization pressure were evaluated. Encapsulation efficiency is high with a satisfied releasing rate. Then, acute otitis media (AOM) animal model was built and diet containing orange peel essential oil microcapsules were administrated to AOM animals. Pharmacological test showed that orange peel essential oil treatment could decrease serum and cochlea malondialdehyde (MDA), immunoglobulins A (IgA), immunoglobulins G (IgG), immunoglobulins M (IgM) levels and increase antioxidant enzymes activities. It can be concluded that orange peel essential oil treatment could decrease oxidative injury in acute otitis media rats.

Abstract
This study reports a continuous prepartion of spherical or hemispherical polymer particles simply utilizing the phase separation in polymer blend films during the coating process. We took an advantage of the strong phase separation between a water-soluble crystalline polymer as a matrix and hydrophobic polymers as minor components. We demonstrated the prepartion of water-soluble polystyrene (PS) particles, nitrilotriacetic acid (NTA)-functionalized PS particles for protein separation, and semiconducting poly(3-hexylthiophene) (P3HT) particles. The sizes of the particles could be controlled by adjusting the film thickness and weight fraction of the minor component polymers in the blend film. It provides a simple facile way to prepare polymer particles in a continous process.

Abstract
The original theoretical model of polyelectrolyte adsorption onto water-dispersed colloid particles is extended to the system of polydisperse droplets of sunflower oil. Polycation (poly(allylamine hydrochloride)) and polyanion (poly(sodium 4-styrenesulfonate)) are taken in the theoretically projected concentrations to perform Layer-by-Layer assembly of a multilayer shell on the surface of oil droplets preliminary stabilized with a protein emulsifier (bovine serum albumin). The velocity of gravitational separation in suspension of encapsulated oil droplets is theoretically predicted and experimentally measured depending on the coating shell's thickness, aiming to clarify the mechanism to control over the separation process. Combining the theory and experimental data, the mass density of a polyelectrolyte multilayer shell assembled in a Layer-by-Layer fashion is obtained. Polyelectrolyte multilayer coated oil droplets are characterized by means of ζ-potential, and particle size measurements, and visualized by scanning electron microscopy.

Abstract
The six fragrances, camphor, citronellal, eucalyptol, limonene, menthol and 4-tert-butylcyclohexyl acetate, which represent different chemical functionalities, were encapsulated with a polymer-blend of ethylcellulose (EC), hydroxypropyl methylcellulose (HPMC) and poly(vinyl alcohol) (PV(OH)) using solvent displacement (ethanol displaced by water). The process gave >or=40% fragrance loading capacity with >or=80% encapsulation efficiency at the fragrance to polymer weight ratio of 1:1 and at initial polymer concentrations of 2000-16,000 ppm and the obtained fragrance-encapsulated spheres showed hydrodynamic diameters of less than 450 nm. The release profile of the encapsulated fragrances, evaluated by both thermal gravimetric and electronic nose techniques, indicated different release characteristics amongst the six encapsulated fragrances. Limonene showed the fastest release with essentially no retention by the nanoparticles, while eucalyptol and menthol showed the slowest release.

Abstract
Spherical polymeric core-shell microcapsules in uniform size were produced by electrospraying with a coaxial nozzle setup. Contrary to the usual coaxial setup, the inner nozzle was slightly bent to touch the inside wall of the outer nozzle. A polymer solution for the core was introduced through the outer nozzle, and the other solution for the shell was supplied through the inner nozzle. The setup greatly increased reproduction of the same results. As a proof of the concept, core-shell microcapsules consisting of a PS or PMMA core and a PCL shell (PS@PCL, PMMA@PCL) were produced. When the volumetric feed rate of the shell-forming PCL solution was higher than that of the core-forming PS or PMMA solution the core-shell structures in uniform size were readily obtained. In contrast, irregular morphologies were observed when the feed rate of the PCL solution was slower or equal to that of the PS or PMMA solution. The size of the colloid was dependent on the relative feed ratio between the polymer solutions as well as the magnitude of applied voltage.
