Spin-coated Cu2ZnSnS4 solar cells: A study on the transformation from ink to film

In this paper, we study the DMSO/thiourea/chloride salt system for synthesis of pure-sulfide Cu 2 ZnSnS 4 (CZTS) thin-film solar cells under ambient conditions. We map out the ink constituents and determine the effect of mixing time and filtering. The thermal behavior of the ink is analyzed, and we find that more than 90% of the solvent has evaporated at 250. C. However, chloride and sulfoxide species are released continually until 500. C, suggesting the advantage of a higher pre-annealing temperature, which is also commonly observed in the spin-coating routines in literature. Another advantage of a higher pre- annealing temperature is that the worm-like pattern in the spin-coated film can be avoided. We hypothesize that this pattern forms as a result of hydrodynamics within the film as it dries, and it causes micro-inhomogeneities in film morphology. Devices were completed in order to finally evaluate the effect of varying thermal exposure during pre- annealing. Contrary to the previous observations, a lower pre-annealing temperature of 250. C results in the best device efficiency of 4.65%, which to the best of our knowledge is the highest efficiency obtained for a puresulfide kesterite made with DMSO. Lower thermal exposure during pre-annealing results in larger grains and a thicker MoS 2 layer at the CZTS/Mo interface. Devices completed at higher pre-annealing temperatures display the existence of either a Cu-S secondary phase or an incomplete sulfurization with smaller grains and a fine-grain layer at the back interface.

Moisture re-adsorption characteristics of hydrochar generated from the Co-hydrothermal carbonization of PVC and alkali coal

Our previous work reported to simultaneously remove the alkali and alkaline earth metals, and chlorine by co hydrothermal carbonization (co-HTC) of high-alkali coal and polyvinyl chloride (PVC) (Fuel Process Technol, 199(2020)106277). This work is to investigate on the moisture re-adsorption characteristics of those hydrochar obtained at various co-HTC operating conditions. The results show that the water re-adsorption capacity of hydrochar was decreased with the circumstance temperature rising from 20 degrees C to 35 degrees C, while it was increased with the air humidity increasing from 50% to 80%. During the co-HTC, the addition of PVC could effectively inhibit the moisture re-adsorption behavior of hydrochar resulting from the adhere of the hydrophobic PVC to the surface of hydrochar as evidenced by SEM. The circumstance temperature had a significant influence on the effective diffusivity D over the humidity. The equilibrium moisture content (EMC) and effective diffusivity (D) could be linearly correlated with surface area and most probable pore size, respectively. The EMC of hydrochar was reduced about 0.6 mg/g as the BET surface area decreased 1 m(2). The reduction of oxygen-containing groups could reduce the adsorption equilibrium time and adsorption heat. Besides, the higher circumstance humidity would cause hydrochar to release higher adsorption heat. As the humidity was increased from 70% to 80%, the heat released by 1 g hydrochar was increased about 13.82-19.63 kJ/mol. Due to the lower EMC and adsorption heat, 300 degrees C was supposed to be a suitable temperature for the co-HTC to obtain hydrophobic hydrochar.

Assessment of Distinct Electrophysiological Parameters in Rectal Biopsies for the Choice of the Best Diagnosis/Prognosis Biomarkers for Cystic Fibrosis

Most cases of Cystic Fibrosis (CF) are diagnosed early in life. However, people with atypical CF forms pose diagnosis dilemmas, requiring laboratory support for diagnosis confirmation/exclusion. Ex vivo analysis of fresh rectal biopsies by Ussing chamber has been the best discriminant biomarker for CF diagnosis/prognosis so far. Here we aimed to evaluate different electrophysiological parameters from Ussing chamber analysis of rectal biopsies from people with CF (PwCF) to establish the one with highest correlations with clinical features as the best CF diagnosis/prognosis biomarker. We analyzed measurements of CFTR-mediated Cl- secretion in rectal biopsies from 143 individuals (similar to 592 biopsies), the largest cohort so far analyzed by this approach. New parameters were analyzed and compared with the previous biomarker, i.e., the IBMX (I)/Forskolin (F)/Carbachol (C)-stimulated short-circuit current (I'(sc-I/F/C)). Correlations with clinical features showed that the best parameter corresponded to voltage measurements of the I/F + (I/F/CCH) response (VI/F+I/F/C), with higher correlations vs. I'(sc-I/F/C) for: sweat chloride (59 vs. 52%), fecal elastase (69 vs. 55%) and lung function, measured by FEV1 (27 vs. 20%). Altogether data show that VI/F+I/F/C is the most sensitive, reproducible, and robust predictive biomarker for CF diagnosis/prognosis effectively discriminating classical, atypical CF and non-CF groups.

A study of the electrochemical and tribological properties of TiN/CrN nano-layer coating deposited on carburized-H13 hot-work steel by Arc-PVD technique

The purpose of this study is to investigate the tribological and corrosion behavior of TiN/CrN nanostructured multilayer coating on H13 carburized hot-work tool steel. Pack cementation and cathodic arc physical vapor deposition (Arc-PVD) techniques were employed to apply adiffused layer and ahard coating, respectively. FE-SEM and XRD were used for coating characterization. Apin-on-disc wear test and Rockwell Cindenter were employed to study wear behavior and adhesion of the coating. To evaluate the corrosion behavior of the specimens, the specimens were tested by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) after immersion in 3.5% sodium chloride solution for 48 hours. The results of potentiodynamic polarization and EIS curves showed that the TiN/CrN nano-layer coating with apre-carburized treatment demonstrated abetter corrosion behavior than H13 and carburized samples. According to the electrochemical test, the current density of the substrate, carburized, and pre-carburized TiN/CrN coated samples were 1.070, 0.875, 0.487 mu A/cm(2), respectively. This improvement in corrosion resistance is due to the high density of the TiN/CrN nano-layers coating that prevents the diffusion of the corrosion solution into the substrate.

Zeta potential changing nanoemulsions based on a simple zwitterion

Hypothesis: Simple zwitterions used as auxiliary agents might have the potential to change the zeta potential of oil-in-water (o/w) nanoemulsions on the mucosa. Experiments: The zwitterion phosphorylated tyramine (p-Tyr) was synthesized by phosphorylation of Boc-tyramine (Boc-Tyr) using phosphoryl chloride (POCl3). It was incorporated with 2% (m/v) in a self emulsifying lipophilic phase comprising Captex 35, Cremophor EL, Capmul MCM and glycerol 85 at a ratio of 30:30:30:10 v/v. Phosphate release and resulting change in zeta potential were evaluated by incubating p-Tyr containing nanoemulsion with isolated intestinal alkaline phosphatase (AP). Mucus permeating behavior was evaluated across mucus obtained from porcine small intestinal mucosa. Subsequently, cellular uptake studies were accomplished on Caco-2 cells. Findings: The p-Tyr loaded nanoemulsion exhibited a mean droplet size of 43 1.7 nm and zeta potential of -8.40 mV. Phosphate moieties were rapidly cleaved from p-Tyr loaded nanoemulsions after incubation with isolated AP resulting in a shift in zeta potential from -8.40 mV to +1.2 mV. p-Tyr loaded nanoemulsion revealed a significantly (p <= 0.001) improved mucus permeation compared to the same nanoemulsion having been pre-treated with AP. Cellular uptake of the zeta potential changing oily droplets was 2.4-fold improved. Phosphorylated zwitterions seem to be an alternative to cationic surfactants and considered as promising auxiliary agents for zeta potential changing nanoemulsions. (C) 2020 The Authors.

Cellulose nanocrystalline hydrogel based on a choline chloride deep eutectic solvent as wearable strain sensor for human motion

Owning to the viscoelastic properties, good biocompatibility and high strain sensitivity, choline chloride-based deep eutectic solvent (DES) hydrogels have been considered to be promising wearable strain sensors for human motion. However, traditional hydrogels are far away from the wearable strain sensor applications caused by their unsatisfied conductivity and weak mechanical properties. Herein, the strategy for functional ionic inorganic/organic interpenetrating (IPN) hydrogels preparation by cyclic freezing/thawing method was successfully developed. Polyvinyl alcohol (PVA) was proposed to dissolve in choline chlorede-based DES as hydrogel matrix for the first time. Encouragingly, the obtained DES/PVA/CNCs/g-C3N4 hydrogel (choline chloride with glucose) exhibits excellent mechanical properties, included excellent tensile strength (approximate to 2.55 MPa), high elongation (approximate to 1200 %) and satisfactory tensile modulus (approximate to 3.65 MPa). Interestingly, the thermal diffusivity (the maximum value was 0.675 W/mK) and conductivity (the maximum value was 0.18 mm(2)/s) of the DES-hydrogels were successfully achieved through adding graphitic-like nitride nanosheet (g-C3N4) and sustainable cellulose nanocrystalline (CNCs). These enhancements were attributed to the synergistic interactions of powerful hydrogen bonding among DES, CNCs, g-C3N4 and PVA chains. More importantly, the as-prepared hydrogels have the potential as a human motion sensor to accurately in-situ detect human activities on the fingers, wrists, elbows and knee joints. Those hydrogel-type strain sensors with flexibility, excellent mechanical properties, self-recovery, good heat transfer, and electrical conductivity have broad application prospects in the fields of intelligent robot, bionic prostheses, and human care areas.

Double membrane based on lidocaine-coated polymyxin-alginate nanoparticles for wound healing: In vitro characterization and in vivo tissue repair

The aim of this study was to develop and characterize a double layer biomembrane for dual drug delivery to be used for the treatment of wounds. The membrane was composed of chitosan, hydroxypropyl methylcellulose and lidocaine chloride (anesthetic drug) in the first layer, and of sodium alginate-polymyxin B sulphate (antibiotic) nanoparticles as the second layer. A product with excellent thickness (0.01-0.02 mm), adequate mechanical properties with respect to elasticity, stiffness, tension, and compatible pH for lesion application has been successfully obtained. The incorporation of the drugs was confirmed analysing the membrane cross-sections by scanning electron microscopy. A strong interaction between the drugs and the functional groups of respective polymers was confirmed by Fourier-Transform Infrared Spectroscopy, thermal analysis and X-ray diffraction. Microbiological assays showed a high antimicrobial activity when polymyxin B was present to act against the Staphylococcus aureus and Pseudomonas aeruginosa strains. Low cytotoxicity observed in a cell viability colorimetric assay and SEM analysis suggest biocompatibility between the developed biomembrane and the cell culture. The in vivo assay allowed visualizing the healing potential by calculating the wound retraction index and by histological analysis. Our results confirm the effectiveness of the developed innovative biomaterial for tissue repair and regeneration in an animal model.

Elucidating the Role of Hydrogen Bond Donor and Acceptor on Solvation in Deep Eutectic Solvents Formed by Ammonium/Phosphonium Salts and Carboxylic Acids

Deep eutectic solvents (DESs) constitute a rapidly emerging class of sustainable liquids that have been widely studied and employed in chemical separations, catalysis, and electrochemistry. The unique physicochemical and solvation properties of DESs can be highly tailored by choosing the appropriate hydrogen bond acceptor (HBA) and hydrogen bond donor (HBD). Understanding the role of the HBA and HBD on the multiple solvation interactions in DESs is important to enable their judicious selection for particular applications. This work constitutes the first study to exploit chromatography to measure solute-solvent interactions of DESs using a wide array of known probe molecules. The constituent components of 20 DESs, formed by ammonium and phosphonium-based salts and carboxylic acids, are systematically modulated to delineate the contribution of the HBA and HBD toward individual solvation properties. Solute-solvent interactions measured in this study are used to interpret and explain the performance of DESs in desulfurization of fuels and extraction of natural products. The results from this study can be used to predict and understand the performance of DESs in various chemical processes where solvation interactions heavily influence outcomes.
