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.

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.

MicroRNAs (miRNAs) play a significant role in axon regeneration following spinal cord injury. However, the functions of numerous miRNAs in axon regeneration within the central nervous system (CNS) remain largely unexplored. Here, we elucidate the positive role of microRNA-2184 (miR-2184) in axon regeneration within zebrafish Mauthner cells (M-cells). The upregulation of miR-2184 in a single M-cell can facilitate axon regeneration, while the specific sponge-induced silencing of miR-2184 leads to impeded regeneration. We show that syt3, , a downstream target of miR-2184, negatively regulates axon regeneration, and the regeneration suppression modulated by syt3 depends on its binding to Ca2 & thorn;. 2 & thorn; . Furthermore, pharmacological stimulation of the cAMP/PKA pathway suggests that changes in the readily releasable pool may affect axon regeneration. Our data indicate that miR-2184 promotes axon regeneration of M-cells within the CNS by modulating the downstream target syt3, , providing valuable insights into potential therapeutic strategies.

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.

Electrocatalytic 5-hydroxymethylfurfural oxidation reaction (HMFOR) provides a promising strategy to convert biomass derivative to high-value-added chemicals. Herein, a cascade strategy is proposed to construct Pd-NiCo2O4 electrocatalyst by Pd loading on Ni-doped Co3O4 and for highly active and stable synergistic HMF oxidation. An elevated current density of 800 mA cm(-2) can be achieved at 1.5 V, and both Faradaic efficiency and yield of 2,5-furandicarboxylic acid remained close to 100% over 10 consecutive electrolysis. Experimental and theoretical results unveil that the introduction of Pd atoms can modulate the local electronic structure of Ni/Co, which not only balances the competitive adsorption of HMF and OH- species, but also promote the active Ni3+ species formation, inducing high indirect oxidation activity. We have also discovered that Ni incorporation facilitates the Co2+ pre-oxidation and electrophilic OH* generation to contribute direct oxidation process. This work provides a new approach to design advanced electrocatalyst for biomass upgrading.

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.

Metal-N-C single-atom catalysts, mostly prepared from pyrolysis of metal-organic precursors, are widely used in heterogeneous electrocatalysis. Since metal sites with diverse local structures coexist in this type of material and it is challenging to characterize the local structure, a reliable structure-property relationship is difficult to establish. Conjugated macrocyclic complexes adsorbed on carbon support are well-defined models to mimic the single-atom catalysts. Metal-N-4 site with four electroneutral pyridine-type ligands embedded in a graphene layer is the most commonly proposed structure of the active site of single-atom catalysts, but its molecular counterpart has not been reported. In this work, we synthesized the conjugated macrocyclic complexes with a metal center (Co, Fe, or Ni) coordinated with four electroneutral pyridinic ligands as model catalysts for CO2 electroreduction. For comparison, the complexes with anionic quadri-pyridine macrocyclic ligand were also prepared. The Co complex with the electroneutral ligand expressed a turnover frequency of CO formation more than an order of magnitude higher than that of the Co complex with the anionic ligand. Constrained ab initio molecular dynamics simulations based on the well-defined structures of the model catalysts indicate that the Co complex with the electroneutral ligand possesses a stronger ability to mediate electron transfer from carbon to CO2.

Humic acid (HA) is a typical refractory organic matter, so it is of great significance to investigate its effect on the performance of Anammox granular sludge. When the dosage of HA day). When HA was between 50 and 100 mg/L, the NRR of Anammox was stable. At this time, the adsorption of HA causes the sludge to gradually turn from red to brown, but the activities of heme and enzymes showed that its capacity was not affected. When HA levels reached 250 mg/L, the NRR dropped to 0.11 kg/(m(3)day). Moderate HA levels promoted the release of extracellular polymeric substance (EPS), but excessive HA levels lead to a decrease in EPS concentrations. HA inhibited Anammox activity, which indirectly hindered the transmission of substrate and accumulated substrate toxicity. Although HA promoted the increase of heterotrophic microbial abundance in Anammox system, the microbial diversity decreased gradually. With the increase of HA concentration, the abundance of Candidatus_Brocadia, the main functional microorganism of Anammox system, decreased gradually, while the abundance of Candidatus_Kuenenia increased gradually.
