Electronic Interactions on Platinum/(Metal-Oxide)-Based Photocatalysts Boost Selective Photoreduction of CO to CH.

By supporting platinum (Pt) and cadmium sulfide (CdS) nanoparticles on indium oxide (In O ), we fabricated a CdS/Pt/In O photocatalyst. Selective photoreduction of carbon dioxide (CO ) to methane (CH ) was achieved on CdS/Pt/In O with electronic Pt-In O interactions, with CH selectivity reaching to 100 %, which is higher than that on CdS/Pt/In O without electronic Pt-In O interactions (71.7 %).

Fast and efficient electrocatalytic oxidation of glucose triggered by CuO-CuO nanoparticles supported on carbon nanotubes.

Electrocatalytic glucose oxidation reaction (GOR) is the key to construct sophisticated devices for fast and accurately detecting trace glucose in blood and food. Herein, a noble-metal-free Cu/C-60 catalyst is fabricated by supporting CuO-CuO nanoparticles on carbon nanotubes through a novel discharge process. For GOR, Cu/C-60 shows a sensitivity as high as 532 μA mM cm, a detection limit as low as 1 μM and a steady-state response time of only 5.

Incorporating MoO Patches into a Ni Oxyhydroxide Nanosheet Boosts the Electrocatalytic Oxygen Evolution Reaction.

The electrocatalytic oxygen evolution reaction from HO (OER) is essential in a number of areas like electrocatalytic hydrogen production from HO. A Ni oxyhydroxide nanosheet (NiNS) is among the most widely studied OER catalysts but still suffers from low activity, sluggish kinetics, and poor stability. Herein, we incorporate MoO patches into NiNS to form a nanosheet with an intimate Ni-Mo interface (NiMoNS) for the OER.

Carbon-Coated Tungsten Oxide Nanospheres Triggering Flexible Electron Transfer for Efficient Electrocatalytic Oxidation of Water and Glucose.

Electrocatalytic oxidation of water (, oxygen evolution reaction, OER) plays crucial roles in energy, environment, and biomedicine. It is a key factor affecting the efficiencies of electrocatalytic reactions conducted in aqueous solution, , electrocatalytic water splitting and glucose oxidation reaction (GOR). However, electrocatalytic OER still suffers from problems like high overpotential, sluggish kinetics, and over-reliance on expensive noble-metal-based catalysts.

Graphene oxide (GO) nanosheets are promising noble-metal-free catalysts. However, the catalytic activity and selectivity of GO are still very low. Herein, GO is first functionalized via noncovalent interactions by an aspartic acid modified anhydride having COOH groups to form A-GO.

Indium-oxide (InO) nanobelts coated by a 5-nm-thick carbon layer provide an enhanced photocatalytic reduction of CO to CO and CH, yielding CO and CH evolution rates of 126.6 and 27.9 μmol h, respectively, with water as reductant and Pt as co-catalyst.

Peptide Self-Assembled Biofilm with Unique Electron Transfer Flexibility for Highly Efficient Visible-Light-Driven Photocatalysis.

Inspired by natural photosynthesis, biomaterial-based catalysts are being confirmed to be excellent for visible-light-driven photocatalysis, but are far less well explored. Herein, an ultrathin and uniform biofilm fabricated from cold-plasma-assisted peptide self-assembly was employed to support Eosin Y (EY) and Pt nanoparticles to form an EY/Pt/Film catalyst for photocatalytic water splitting to H2 and photocatalytic CO2 reduction with water to CO, under irradiation of visible light. The H2 evolution rate on EY/Pt/Film is 62.

A conserved RAD6-MDM2 ubiquitin ligase machinery targets histone chaperone ASF1A in tumorigenesis.

Chromatin is a highly organized and dynamic structure in eukaryotic cells. The change of chromatin structure is essential in many cellular processes, such as gene transcription, DNA damage repair and others. Anti-silencing function 1 (ASF1) is a histone chaperone that participates in chromatin higher-order organization and is required for appropriate chromatin assembly.

Microarray Analysis Reveals Potential Biological Functions of Histone H2B Monoubiquitination.

Histone H2B monoubiquitination is a key histone modification that has significant effects on chromatin higher-order structure and gene transcription. Multiple biological processes have been suggested to be tightly related to the dynamics of H2B monoubiquitination. However, a comprehensive understanding of biological roles of H2B monoubiquitination is still poorly understood.
