Abstract
Nowadays, ductile and conducting polymeric materials are highly utilizable in the realm of stretchable organic electronics. Here, mechanically ductile and electrically conducting free-standing films are fabricated by blending different solvents such as dimethyl sulfoxide (DMSO), diethylene glycol (DEG) and N,N-dimethylformamide (DMF), and salts such as silver nitrate (AgNO3), zinc chloride (ZnCl2), copper chloride (CuCl2) and indium chloride (InCl3) with the homogeneous solution of poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) and poly(vinyl alcohol) (PVA) through solution casting method. The presence of salt modifies the PEDOT conformation from benzoid to quinoid, and induces the evolution of different morphologies. ZnCl2 or AgNO3 blended films have lower surface roughness and good miscibility with polymers, while CuCl2 or InCl3 blended films have relatively higher surface roughness as well as irregularly distributed surface morphology. Some crystalline domains are also formed due to the salt agglomeration. The presence of salt inside PEDOT:PSS/PVA/solvent system changes the current-voltage response from non-linear to linear. Among all the films, zinc salt blended PEDOT:PSS/PVA/DMSO, PEDOT:PSS/PVA/DEG and PEDOT:PSS/PVA/DMF films have higher conductivity, and zinc salt blended PEDOT:PSS/PVA/DEG film shows the highest conductivity of 0.041 ± 0.0014 S cm-1, while silver salt blended PEDOT:PSS/PVA/DMSO, PEDOT:PSS/PVA/DEG and PEDOT:PSS/PVA/DMF films have higher elongation at break, and silver salt blended PEDOT:PSS/PVA/DMSO film shows the highest elongation at break of 670 ± 31%. Both the charge carriers, i.e., electrons and ions, contribute to the electrical conduction, and the presence of hydrogen bonds and ionic interactions among PEDOT+, PSS-, PVA, residual solvent, salt cations and anions modifies the film behaviours. Among all the films, ZnCl2 blended PEDOT:PSS/PVA/DMSO film offers relatively superior behaviours having higher conductivity (0.025 ± 0.0013 S cm-1) and elongation at break (517 ± 15%), and therefore can have potential applications in the fields of wearable devices, bioelectronics, etc.

Abstract
Meso-2,3-dimercaptosuccinic acid (DMSA) is one of the efficient chelating reagents for treating the toxicity of several heavy metals. Currently, nanomaterial have been applied to various parts including zinc Oxide nanoparticles (ZnONPs). ZnONPs have several properties and are used as many applications. An increasing the amount of ZnONPs in commercial products causes risks related to free radicals or reactive oxygen species (ROS) in the body, leading to oxidative stress and eventually to the cancer process. In the present work, we mainly focused on the study of DMSA complexes in term of metal ions and nanoparticles. The synthesis of DMSA-ZnONPs by the co-precipitation method were determined, followed by Scanning Electron Microscope, Fourier Transform Infrared Spectroscopy and UV-Vis spectrophotometry confirming successful synthesis process. The stability study of the DMSA complexes with metal ions and ZnONPs were determined and evaluated the stability constant (K), with the Benesi- Hildebrand equation. All complexes with DMSA were formed at a 1:2 ratio by the dithiol group and the carboxyl group with different stability constants. Therefore, these results can help of an understanding of the interaction and its behavior between DMSA with heavy metal ion and ZnONPs. In addition, the stable structure of DMSA and metal ion complexes were predicted using the B3LYP and the 6-31G (d,p) basis set which the most stable structure of meso-DMSA was 2R,3S conformation and the metal ions and DMSA complexes was complex 2a with the binding energy of -1553.46 kcal mol-1.

CHEMOSPHERE 2020; 260:127649. [PMID: 32688323 DOI: 10.1016/j.chemosphere.2020.127649] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Revised: 06/20/2020] [Accepted: 07/07/2020] [Indexed: 06/11/2023]
Abstract
Post-digestion treatment is an important step during sample preparation to facilitate the removal of undigested materials for better detection of ingested microplastics. Sieving, density separation with zinc chloride solution (ZnCl2), and oil extraction protocol (OEP) have been introduced in separating microplastics from sediments. The clean-up methods are rarely highlighted in previous studies, especially in the separation of microplastics from marine biota. Thus, this study proposed and compared the suitability of three techniques, which can reduce the number of undigested particles from the digestate of GIT and gills. Our result has shown excellent removal of non-plastics materials and reduces the coloration of filter paper in all treated samples. Both sieving and density separation achieved optimum post-digestion efficiencies of >95% for both GIT and gill samples, which former showed no effect on polymer integrity. Additionally, high recovery rate was obtained for the larger size microplastics (>500 μm) with approximately 97.7% (GIT) and 95.7% (gill), respectively. Exposure to the ZnCl2 solution led to a significant loss of smaller size PET and changed the absorption spectrums of all tested polymers. Particle morphology determined by SEM revealed such exposure eroded the surface of PET fragments and elemental analysis has shown detectable peaks of zinc and chlorine appeared. Low microplastics recoveries were achieved through OPE and residue of oil was observed from the infrared spectrum of all tested polymer. The findings demonstrate sieving with size fractioning can provide exceptional removal of non-plastics materials from the digestate of GIT and gill samples.
