Abstract
BACKGROUND 1,5-Diamino-2-hydroxy-pentane (2-OH-PDA), as a new type of aliphatic amino alcohol, has potential applications in the pharmaceutical, chemical, and materials industries. Currently, 2-OH-PDA production has only been realized via pure enzyme catalysis from lysine hydroxylation and decarboxylation, which faces great challenges for scale-up production. However, the use of a cell factory is very promising for the production of 2-OH-PDA for industrial applications, but the substrate transport rate, appropriate catalytic environment (pH, temperature, ions) and separation method restrict its efficient synthesis. Here, a strategy was developed to produce 2-OH-PDA via an efficient, green and sustainable biosynthetic method on an industrial scale. RESULTS In this study, an approach was created for efficient 2-OH-PDA production from L-lysine using engineered E. coli BL21 (DE3) cell catalysis by a two-stage hydroxylation and decarboxylation process. In the hydroxylation stage, strain B14 coexpressing L-lysine 3-hydroxylase K3H and the lysine transporter CadB-argT enhanced the biosynthesis of (2S,3S)-3-hydroxylysine (hydroxylysine) compared with strain B1 overexpressing K3H. The titre of hydroxylysine synthesized by B14 was 2.1 times higher than that synthesized by B1. Then, in the decarboxylation stage, CadA showed the highest hydroxylysine activity among the four decarboxylases investigated. Based on the results from three feeding strategies, L-lysine was employed to produce 110.5 g/L hydroxylysine, which was subsequently decarboxylated to generate a 2-OH-PDA titre of 80.5 g/L with 62.6% molar yield in a 5-L fermenter. In addition, 2-OH-PDA with 95.6% purity was obtained by solid-phase extraction. Thus, the proposed two-stage whole-cell biocatalysis approach is a green and effective method for producing 2-OH-PDA on an industrial scale. CONCLUSIONS The whole-cell catalytic system showed a sufficiently high capability to convert lysine into 2-OH-PDA. Furthermore, the high titre of 2-OH-PDA is conducive to separation and possesses the prospect of industrial scale production by whole-cell catalysis.

Abstract
HYPOTHESIS A unique adhesion-shielding (AS)-based method could be used to manufacture magnetic Janus nanoparticles (IM-JNPs) of promising interfacial activities, asymmetric surface wettability, and great performance on deoiling from oily wastewater under the external magnetic field. EXPERIMENTS The IM-JNPs were characterized using scanning electron microscope (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and Fourier-transform infrared spectroscopy (FTIR). The interfacial properties of IM-JNPs were investigated by the measurements of interfacial pressure-area isotherms (π-A), oil-water interfacial tension, and the related crumpling ratio. The Langmuir-Blodgett (L-B) technique was used to determine the asymmetric surface wettability of the IM-JNPs. The performance and recyclability of IM-JNPs for treating oily wastewater were also investigated. FINDINGS Using the proposed AS-based method, 17.9 g IM-JNPs were synthesized at a time and exhibited excellent interfacial properties, as indicated by decreasing oil-water interfacial tension from 38 to 27 mN/m. The crumpling behavior of the oil droplet further demonstrated the irreversible deposition of IM-JNPs at the oil droplet surfaces. The L-B technique and water contact angle measurement confirmed the asymmetric surface wettability of the IM-JNPs. The IM-JNPs were applied to successful removal of > 90% emulsified oil droplets from the household-produced oily wastewater under the external magnetic field while realizing facile recyclability and regeneration.

Abstract
An improved process for chemical synthesis of l-fructose with high purity in large scale from readily available l-sorbose is described. In general, this synthetic scheme is characterized by inexpensive and easily available starting materials, simple and safe experimental procedures, short time period, low environmental impact, and great potential for scaling up. The scale-up experiment (100 g) was carried out to provide 42.7 g of l-fructose with high HPLC purity of 99.65% in total yield of 50.2%. Consequently, the described improvements would be helpful for those who may wish to use l-fructose and promoting the further evaluation of applications of l-fructose.

Abstract
Boron nitride nanotube (BNNT) has similar tubular nanostructure as carbon nanotube (CNT) in which boron and nitrogen atoms arranged in a hexagonal network. Owing to the unique atomic structure, BNNT has numerous excellent intrinsic properties such as superior mechanical strength , high thermal conductivity, electrically insulating behavior, piezoelectric property, neutron shielding capability, and oxidation resistance. Since BNNT was first synthesized in 1995, developing efficient BNNT production route has been a significant issue due to low yield and poor quality in comparison with CNT, thus limiting its practical uses. However, many great successes in BNNT synthesis have been achieved in recent years, enabling access to this material and paving the way for the development of promising applications. In this article, we discussed current progress in the production of boron nitride nanotube, focusing on the most common and effective methods that have been well established so far. In addition, we presented various applications of BNNT including polymer composite reinforcement, thermal management packages, piezo actuators, and neutron shielding nanomaterial.

Abstract
Layer-by-layer (LbL) based self-assembly of nanoparticles is an emerging and powerful method to develop multifunctional and tissue responsive nanomedicines for a broad range of diseases. This unique assembly technique is able to confer a high degree of modularity, versatility, and compositional heterogeneity to nanoparticles via the sequential deposition of alternately charged polyelectrolytes onto a colloidal template. LbL assembly can provide added functionality by directly incorporating a range of functional materials within the multilayers including nucleic acids, synthetic polymers, polypeptides, polysaccharides, and functional proteins. These materials can be used to generate hierarchically complex, heterogeneous thin films on an extensive range of both traditional and novel nanoscale colloidal templates, providing the opportunity to engineer highly precise systems capable of performing the numerous tasks required for systemic drug delivery. In this review, we will discuss the recent advancements towards the development of LbL nanoparticles for drug delivery and diagnostic applications, with a special emphasis on the incorporation of biostability, active targeting, desirable drug release kinetics, and combination therapies into LbL nanomaterials. In addition to these topics, we will touch upon the next steps for the translation of these systems towards the clinic.
