Liquid Metal Nanobiohybrids for High-Performance Solar-Driven Methanogenesis via Multi-Interface Engineering.
Angew Chem Int Ed Engl
January 2025
Fujian Agriculture and Forestry University, College of Resources and Environment, CHINA.
Nanobiohybrids for solar-driven methanogenesis present a promising solution to the global energy crisis. However, conventional semiconductor-based nanobiohybrids face challenges such as limited tunability and poor biocompatibility, leading to undesirable spontaneous electron and proton transfer that compromise their structural stability and CH4 selectivity. Herein, we introduced eutectic gallium-indium alloys (EGaIn), featuring a self-limiting surface oxide layer surrounding the liquid metal core after sonication, integrated with Methanosarcina barkeri (M.

The present work introduces and validates an artificial cell free system for the synthesis of acetoin from ethanol, representing a greener alternative to conventional chemical synthesis. The one pot multi-enzymatic system, which employs pyruvate decarboxylase from Zymobacter palmae (ZpPDC), alcohol dehydrogenase from Saccharomyces cerevisiae (ScADH), and NADH oxidase from Streptococcus pyogenes (SpNOX), achieves nearly 100 % substrate conversion and reaction yield within 6 h under optimal conditions (pH 7.5, enzyme activities: ZpPDC 100 U·mL, ScADH 50 U·mL, SpNOX 127 U·mL, and 1 mM NAD).

Biotechnology Program, Center for Sustainable Development, College of Arts and Sciences, Qatar University, Doha 2713, Qatar. Electronic address:
Polyhydroxyalkanoates (PHAs) are biodegradable and biocompatible polymers that can replace conventional plastics in different sectors. However, PHA commercialization is hampered due to their high production cost resulting from the use of high purity substrates, their low conversion into PHAs by using conventional microbial chassis and the high downstream processing cost. Taking these challenges into account, researchers are focusing on the use of waste by-products as alternative low-cost feedstocks for fast-growing and contamination-resistant halophilic microorganisms (Bacteria, Archaea…).

January 2025
Department of Emergency, Longhua Hospital, Shanghai University of Traditional Chinese Medicine, Shanghai, 200032, China.
Objective: To evaluate the effect and safety of Chinese medicine (CM) Fuzheng Huazhuo Decoction (FHD) in treating patients with coronavirus disease 2019 (COVID-19) who persistently tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Methods: This retrospective cohort study was conducted at Shanghai New International Expo Center shelter hospital in China between April 1 and May 30, 2022. Patients diagnosed as COVID-19 with persistently positive SARS-CoV-2 reverse transcription-polymerase chain reaction (RT-PCR) test results for ⩾8 days after diagnosis were enrolled.
Beyond Tradition: A MOF-On-MOF Cascade Z-Scheme Heterostructure for Augmented CO Photoreduction.
Small
January 2025
Beijing Key Laboratory for Green Catalysis and Separation and Department of Chemical Engineering, College of Materials Science and Engineering, Beijing University of Technology, Beijing, 100124, P. R. China.
Metal-organic frameworks (MOFs) are rigorously investigated as promising candidates for CO capture and conversion. MOF-on-MOF heterostructures integrate bolstered charger carrier separation with the intrinsic advantages of MOF components, exhibiting immense potential to substantially escalate the efficiency of photocatalytic CO reduction (CORR). However, the structural and compositional complexity poses significant challenges to the controllable development of these heterostructures.
