A novel polybenzimidazole (PBI)-based trilayer membrane assembly is developed for application in vanadium redox flow battery (VRFB). The membrane comprises a 1 mu m thin cross-linked poly[2,2'-(p-oxydiphenylene)-5,5'-bibenzimidazole] (OPBI) sandwiched between two 20 mu m thick porous OPBI membranes (p-OPBI) without further lamination steps. The trilayer membrane demonstrates exceptional properties, such as high conductivity and low area-specific resistance (ASR) of 51 mS cm(-1) and 81 m Omega cm(2), respectively. Contact with vanadium electrolyte increases the ASR of trilayer membrane only to 158 m Omega cm(2), while that of Nafion is 193 m Omega cm(2). VO2+ permeability is 2.73 x 10(-9) cm(2) min(-1), about 150 times lower than that of Nafion NR212. In addition, the membrane has high mechanical strength and high chemical stability against VO2+. In VRFB, the combination of low resistance and low vanadium permeability results in excellent performance, revealing high Coulombic efficiency (>99%), high energy efficiency (EE; 90.8% at current density of 80 mA cm(-2)), and long-term durability. The EE is one of the best reported to date.

The key to designing photocatalysts is to orient the migration of photogenerated electrons to the target active sites rather than dissipate at inert sites. Herein, we demonstrate that the doping of phosphorus (P) significantly enriches photogenerated electrons at Ni active sites and enhances the performance for CO2 reduction into syngas. During photocatalytic CO2 reduction, Ni single-atom-anchored P-modulated carbon nitride showed an impressive syngas yield rate of 85 mu mol g(cat)(-1) h(-1) and continuously adjustable CO/H-2 ratios ranging from 5:1 to 1:2, which exceeded those of most of the reported carbon nitride-based single-atom catalysts. Mechanistic studies reveal that P doping improves the conductivity of catalysts, which promotes photogenerated electron transfer to the Ni active sites rather than dissipate randomly at low-activity nonmetallic sites, facilitating the CO2-to-syngas photoreduction process.

The successful utilization of an eco-friendly and biocompatible parylene-C substrate for high-performance solution-processed double-walled carbon nanotube (CNT) electrode-based perovskite solar cells (PSCs) was demonstrated. Through the use of a novel inversion transfer technique, vertical separation of the binders from the CNTs was induced, rendering a stronger p-doping effect and thereby a higher conductivity of the CNTs. The resulting foldable devices exhibited a power conversion efficiency of 18.11%, which is the highest reported among CNT transparent electrode-based PSCs to date, and withstood more than 10,000 folding cycles at a radius of 0.5 mm, demonstrating unprecedented mechanical stability. Furthermore, solar modules were fabricated using entirely laser scribing processes to assess the potential of the solution-processable nanocarbon electrode. Notably, this is the only one to be processed entirely by the laser scribing process and to be biocompatible as well as eco-friendly among the previously reported nonindium tin oxide-based perovskite solar modules. Eco-friendly and biocompatible parylene substrate induced the vertical separation of binders from carbon nanotubes (CNTs) via an inversion technique for solution-processed double-walled CNT electrodes. By applying them to perovskite solar cells, a record power conversion efficiency of 18.11% with a mechanical stability of over 10,000 folding cycles was achieved. The first entirely laser-scribed solar modules were fabricated using the same electrode, showcasing the potential for e-skin applications. image

A conventional electrode composite for rechargeable zinc-ion batteries (ZIBs) includes a binder for strong adhesion between the electrode material and the current collector. However, the introduction of a binder leads to electrochemical inactivity and low electrical conductivity, resulting in the decay of the capacity and a low rate capability. We present a binder- and conducting agent-free VO2 composite electrode using in situ polymerization of dopamine on a flexible current collector of pyroprotein-based fibers. The as-fabricated composite electrode was used as a substrate for the direct growth of VO2 as a self-supported form on polydopamine-derived pyroprotein-based fibers (pp-fibers@VO2(B)). It has a high conductivity and flexible nature as a current collector and moderate binding without conventional binders and conducting agents for the VO2(B) cathode. In addition, their electrochemical mechanism was elucidated. Their energy storage is induced by Zn2+/H+ coinsertion during discharging, which can be confirmed by the lattice expansion, the formation of by-products including Znx(OTf)y(OH)(2x-y)center dot nH(2)O, and the reduction of V4+ to V3+. Furthermore, the assembled Zn//pp-fibers@VO2(B) pouch cells have excellent flexibility and stable electrochemical performance under various bending states, showing application possibilities for portable and wearable power sources.

In this work, the perovskite LaZnO3 was synthesized via sol-gel method and applied for photocatalytic treatment of sulfamethizole (SMZ) antibiotics under visible light activation. SMZ was almost completely degraded (99.2% + 0.3%) within 4 hr by photocatalyst LaZnO3 at the optimal dosage of 1.1 g/L, with a mineralization proportion of 58.7% + 0.4%. The efficient performance of LaZnO3 can be attributed to its wide-range light absorption and the appropriate energy band edge levels, which facilitate the formation of active agents such as center dot O2 -, h+ , and center dot OH. The integration of RP-HPLC/Q-TOF-MS and DFT-based computational techniques revealed three degradation pathways of SMZ, which were initiated by the deamination reaction at the anilin ring, the breakdown of the sulfonamide moieties, and a process known as Smile-type rearrangement and SO2 intrusion. Corresponding toxicity of SMZ and the intermediates were analyzed by quantitative structure activity relationship (QSAR), indicating the effectiveness of LaZnO3-based photocatalysis in preventing secondary pollution of the intermediates to the ecosystem during the degradation process. The visible -light -activated photocatalyst LaZnO3 exhibited efficient performance in the occurrence of inorganic anions and maintained high durability across multiple recycling tests, making it a promising candidate for practical antibiotic treatment.

Micro-light-emitting diodes (mu LEDs) have gained significant interest as an activation source for gas sensors owing to their advantages, including room temperature operation and low power consumption. However, despite these benefits, challenges still exist such as a limited range of detectable gases and slow response. In this study, we present a blue mu LED-integrated light-activated gas sensor array based on SnO2 nanoparticles (NPs) that exhibit excellent sensitivity, tunable selectivity, and rapid detection with micro-watt level power consumption. The optimal power for mu LED is observed at the highest gas response, supported by finite-difference time-domain simulation. Additionally, we first report the visible light-activated selective detection of reducing gases using noble metal-decorated SnO2 NPs. The noble metals induce catalytic interaction with reducing gases, clearly distinguishing NH3, H-2, and C2H5OH. Real-time gas monitoring based on a fully hardware-implemented light-activated sensing array was demonstrated, opening up new avenues for advancements in light-activated electronic nose technologies.

The spaceborne platform has unprecedently provided the global eddy-permitting (typically about 0.25 degrees) products of sea surface salinity (SSS), however the existing SSS products can hardly resolve mesoscale motions due to the heavy noises therein and the over-smoothing in denoising processes. By means of the multi-fractal fusion (MFF), the high-resolution SSS product is synthesized with the template of sea surface temperature (SST). Two low-resolution SSS products and four SST products are considered as the source data and the templates respectively to determine the best combination. The fused products are validated by the in situ observations and intercompared via SSS maps, Singularity Exponent maps and wavenumber spectra. The results demonstrate that the MFF can perform a good work in mitigating the noises and improving the resolution. The combination of the climate change initiative SSS and the remote sensing system SST can produce the 0.1 degrees denoised product whose global mean standard derivation of salinity against Argo is 0.21 and the feature resolution can reach 30-40 km.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19, encodes several accessory proteins that have been shown to play crucial roles in regulating the innate immune response. However, their expressions in infected cells and immunogenicity in infected humans and mice are still not fully understood. This study utilized various techniques such as luciferase immunoprecipitation system (LIPS), immunofluorescence assay (IFA), and western blot (WB) to detect accessory protein-specific antibodies in sera of COVID-19 patients. Specific antibodies to proteins 3a, 3b, 7b, 8 and 9c can be detected by LIPS, but only protein 3a antibody was detected by IFA or WB. Antibodies against proteins 3a and 7b were only detected in ICU patients, which may serve as a marker for predicting disease progression. Further, we investigated the expression of accessory proteins in SARS-CoV-2-infected cells and identified the expressions of proteins 3a, 6, 7a, 8, and 9b. We also analyzed their ability to induce antibodies in immunized mice and found that only proteins 3a, 6, 7a, 8, 9b and 9c were able to induce measurable antibody productions, but these antibodies lacked neutralizing activities and did not protect mice from SARS-CoV-2 infection. Our findings validate the expression of SARS-CoV-2 accessory proteins and elucidate their humoral immune response, providing a basis for protein detection assays and their role in pathogenesis.

For the porous-membrane-based osmotic energy generator, the potential synergistic enhancement mechanism of various key parameters is still controversial, especially because optimizing the trade-off between permeability and selectivity is still a challenge. Here, to construct a permeability and selectivity synergistically enhanced osmotic energy generator, the two-dimensional porous membranes with tunable charge density are prepared by inserting sulfonated polyether sulfone into graphene oxide. Influences of charge density and pore size on the ion transport are explored, and the ionic behaviors in the channel are calculated by numerical simulations. The mechanism of ion transport in the process is studied in depth, and the fundamental principles of energy conversion are revealed. The results demonstrate that charge density and pore size should be matched to construct the optimal ion channel. This collaborative enhancement strategy of permeability and selectivity has significantly improved the output power in osmotic energy generation; compared to the pure graphene oxide membrane, the composite membrane presents almost 20 times improvement. Transmembrane properties of ions are crucial for osmotic energy conversion. In this study, to achieve synergistic enhancement of permeability and selectivity, the mechanism of charge density and pore size in ion transport are studied in-depth. Results of the experiment and theoretical calculation demonstrate that the charge density and pore size should be matched to construct the optimal ion channel. This collaborative enhancement strategy of permeability and selectivity is expected to promote the utilization of clean energy in the future. image
