Copper Doping Enhances the Activity and Selectivity of Atomically Precise Ag44 Nanoclusters for Photocatalytic CO2 Reduction

open access: yesAdvanced Functional Materials, EarlyView.
By a simple anti‐Galvanic reaction, up to six copper atoms could be preferably doped into the Ag2(SR)5 staple motifs and Ag20 dodecahedral shell of an atomically precise Ag44(SR)30 nanocluster. When anatase TiO2 is used as substrate, the (AgCu)44/TiO2 photocatalyst exhibited much improved activity in photocatalytic CO2 reduction compared to Ag44/TiO2 ...

Self‐supportive Three‐Way Photoelectrochemical System Achieving Uranium Recycling, Organic Oxidation, and Electricity Generation in Complex Waters

open access: yesAdvanced Functional Materials, EarlyView.
A self‐sustaining solar photoelectrochemical cell (SS‐PEC) is developed to recover uranium from aqueous UO22+ with concurrent organic oxidation and electricity production. The monolithical photoanode directly captures electrons from organic compounds, leading to the oxidation of organic compounds and the decomposition of uranium‐organic complexes ...

Critical Behaviour of the Heat Capacity Near the α-β Phase Transition in Quartz

open access: yesHigh Temperature Materials and Processes, 2013
The α-β transition (TQ = 578°C) is studied in quartz by analyzing the experimental heat capacity Cp data taken from the literature, using a power-law formula. Values of the critical exponent α for Cp are extracted below and above TQ, which describe the α-

Achieving Chemical Recognition, Recycling, and Circularity With Radical Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
Here, innovative 3D radical nanostructures based on 4,4′‐dicyano‐2,2′‐biphenylene‐fused tetrazolinyl radical, fabricated on interdigitated gold‐SiO2 hybrid surfaces are presented. They retain their magnetic properties, their morphology and size can can tune, selectively remove them from specific substrate regions using distilled water, and return the ...

The Performance of Quartz Dosimeter with Range to MGy

open access: yesJournal of Isotopes, 2022
To study the new type of dosimeter with a dose up to the ultra-high dose range of MGy, the electron spin resonance (ESR) method is used to measure the signal intensity of the sample irradiated by gamma rays or electron beams.

Reversible Phase Transitions Enable Cyclic Isothermal CO2 Capture in Redox‐Activated Perovskite‐Structured Sorbents

open access: yesAdvanced Functional Materials, EarlyView.
Perovskite‐structured SrMnO3 can cyclically and reversibly capture and release CO2 via redox‐enabled phase transitions at constant temperature. The efficacy of this novel redox‐activated CO2 sorbent is demonstrated via sorption‐enhanced steam methane reforming.

Quartz Cherenkov Counters for Fast Timing: QUARTIC

open access: yes, 2012
We have developed particle detectors based on fused silica (quartz) Cherenkov radiators read out with micro-channel plate photomultipliers (MCP-PMTs) or silicon photomultipliers (SiPMs) for high precision timing (Sigma(t) about 10-15 ps). One application
