Summary: In this study, we investigated the bifunctional activity of GH46 chitosanases based on cleavage specificity classification. We found that CsnMHK1 from Bacillus circulans MH-K1, previously thought to only hydrolyze chitosan, can also hydrolyze cello-substrates. Comparison with GH8 chitosanase provided new insights into substrate specificities and challenged the current understanding of chitosanase classification. These findings contribute to our understanding of chitosanase recognition and hydrolysis, which is valuable for future studies.

Summary: The study proposed a novel approach using nanoscale zerovalent iron (nZVI) to simultaneously promote microalgal activity and nutrient uptake from wastewater. By enhancing metabolic pathways and intracellular regulations, nZVI significantly increased biomass production, NH4+N and PO43--P uptake rates. The findings suggest that nZVI can regulate various metabolisms and gene expressions, providing a molecular mechanism for enhancing microalgal activities in wastewater treatment.

Summary: In this study, highly efficient bifunctional electrocatalysts for water splitting have been designed by depositing layered double hydroxides (LDH) on Co3O4/NF nanosheets arrays to form Co3+-rich LDH-Co3O4/NF materials. These materials demonstrated excellent electrochemical activity due to the optimized electronic states and unique sheet-on-sheet hierarchical structure, which accelerated reaction kinetics and provided convenient charge transfer pathways. The strategy reported in this work may pave the way for the design of excellent electrocatalysts for water splitting.

Summary: In this study, CeO2 nanospheres embedded in NiO nanoflakes were synthesized and demonstrated to have bifunctional activity for the oxygen evolution reaction and oxygen reduction reaction (OER/ORR). The CeO2/NiO-2 nanocomposite showed outstanding OER/ORR activity and stability compared to other compositions and benchmark catalysts. The unique morphology of CeO2 nanospheres embedded in NiO nanoflakes facilitated the exposure of active sites with the bifunctional nature of the catalyst. The electronic synergy between CeO2 and NiO contributed to the formation of oxygen vacancy defects and accessible active sites.

Summary: High performance in electrochemical energy/catalysis/sensing requires the timely arrival and departure of electrons, ions, and molecules. Architectural design of mesoscale porous nanostructures ensures timely electronic, ionic, and mass transport to electrified reactive interfaces. This study investigates the nature of proton transport in TiO2 aerogels modified with Au nanoparticles, revealing that the presence of Au nanoparticles affects proton transport along the oxide network, reducing resistance and increasing ionicity. The findings highlight the importance of intimate interaction between Au nanoparticles and TiO2 nanoparticles for efficient proton transport.

Summary: CeO2 aerogel-supported Ni(OH)(2) nanoparticles demonstrate superior activity and stability in CO oxidation reaction. The intimate contact between Ni(OH)2 NPs and the bonded nanoparticulate CeO2 network prevents the conversion to NiO. CO has lower adsorption energy on Ni(OH)(2) compared to NiO, resulting in reduced poisoning of active surface sites.

Summary: For practical applications with energy density demands greater than 3 mA h cm(-2), the electrode structure of lithium-sulfur batteries needs to be redesigned. Freestanding carbon nanofoam papers derived from resorcinol-formaldehyde aerogels provide a conductive mesoporous network and facilitate electrolyte transport. Vapor-phase sulfur infiltration allows for high areal capacities up to 4.1 mA h cm(-2) at sulfur loadings of 6.4 mg cm(-2) by fully penetrating >100 μm thick electrodes and conformally coating the carbon aerogel surface. Electrode performance can be optimized for either energy density or power density by tuning sulfur loading, pore size, and electrode thickness.

Summary: In this study, the heat flow during silicon lithiation was investigated using isothermal microcalorimetry, and the composition of the solid electrolyte interphase was elucidated using complementary techniques. The research found that nanosized silicon electrodes generate more heat than micrometer-sized ones, and the introduction of amorphous carbon significantly alters the heat flow profile. Vinylene carbonate is an effective electrolyte additive that increases the heat dissipation of the electrode.
