Mechanism of Dihydrogen Splitting by An Apparent Bimetallic Frustrated Lewis Pair based on Ir(III)/Pt(0)
(Wiley-Blackwell, 2023)
The incorporation of transition metals into frustrated Lewis pairs (FLPs) offers multiple opportunities for bond activation and catalysis. In this work, we explore the combination of the Lewis acidic Ir(III) cation ...

Harnessing the unusually strong improvement of thermoelectric performance of AgInTe2 with nanostructuring
(Royal Society of Chemistry, 2023-07-20)
Nanostructuring is a well-established approach to improve the thermoelectric behavior of materials. However, its effectiveness is restricted if excessively small particle sizes are necessary to considerably decrease the ...

New perspectives for neutron capture measurements in the upgraded CERN-n_TOF Facility
(E D P Sciences, 2023)
The n_TOF facility has just undergone in 2021 a major upgrade with the installation of its third generation spallation target that has been designed to optimize the performance of the two n_TOF time-of-flight lines. This ...

Proton halo effects in the 8B+64Zn collision around the Coulomb barrier
(IOP Publishing Ltd, 2023)
The 8B+64Zn reaction at 38.5 MeV has been studied at HIE-ISOLDE CERN to investigate proton halo effect on the reaction dynamics. For the first time it was used the only existing post-accelerated 8B beam. The measured elastic ...

Flash Joule Heating-Boro/Carbothermal Reduction (FJH-BCTR): An approach for the instantaneous synthesis of transition metal diborides
(Elsevier, 2024-01-09)
Transition metal diborides (TMB2), such as ZrB2 and HfB2, are a class of ultra-high-temperature ceramics (UHTCs) that have attracted considerable attention due to their performance in extreme environments. Their implementation ...

Analysis of error mechanisms in switched-current Sigma-Delta modulators
(Springer, 2004)
This paper presents a systematic analysis of the major switched-current (SI) errors and their influence on the performance degradation of ΣΔ Modulators (ΣΔMs). The study is presented in a hierarchical systematic way. First, ...

Interlaboratory Reproducibility in Growth and Reporter Expression in the Cyanobacterium Synechocystis sp. PCC 6803
(American Chemical Society, 2023)
In recent years, a plethora of new synthetic biology tools for use in cyanobacteria have been published; however, their reported characterizations often cannot be reproduced, greatly limiting the comparability of results ...

New Concept for High Temperature Thermal Energy Storage Using a Concrete Tank
(EuroSun, 2022)
The use of concrete is showing great potential as thermal energy storage material for concentrating solar power plants (CSP) due to its versatility, relatively low cost, and the possibility to reach a high operating ...

Effect of the crystal chemistry on the hydration mechanism of swelling micas
(Elsevier, 2017)
Swelling and dehydration under minor changes in temperature and water vapor pressure is an important property that clays and clay minerals exhibit. In particular, their interlayer space, the solid-water interface and the ...

Extended X-ray absorption fine structure (EXAFS) investigations of Ti bonding environment in sputter-deposited nanocomposite TiBC/a-C thin films
(Institute of Physics Publishing, 2014)
In this study, we have successfully used the extended X-ray absorption fine structure (EXAFS) technique at the Ti-K edge to extract the local structure in a set of nanocomposite TiBC/a-C coatings deposited by a combined ...
