Since the discovery of the Honda-Fujishima effect of water splitting[1] using a titanium dioxide (TiO2) electrode in the early 1970s, numerous studies have been conducted and are still growing on photocatalytic reactions of TiO2. Titanium dioxide serves as a model case for the mechanistic studies of photocatalysis, but it has a serious drawback as a photocatalyst for water splitting: the band g...

Two alkaline earth metal-based carboxylate systems, [Mg(HL)(H2O)2]n (1) and [Ca(H2L)2]n (2) (H3L = chelidamic acid) have been hydrothermally synthesized, and characterized by single-crystal X-ray diffraction, IR, elemental analysis, and thermo-gravimetric analysis. Compound 1 has a 2D structure incorporating two water molecules. The dehydrated species, 1a, generated from 1 by removal of the coo...

The beam dump is a critical component for the in-flight fragment separator using high-power primary beams at the rare isotope science project (RISP) in Korea. The maximum beam power is planned to be 400 kW, and a third of the primary beam power deposits at the isotope production target and the rest are dissipated at the beam dump. The beam dump is designed to be a rotating water drum, which is ...

At the National Institute of Metrological Research (INRiM), the first European thermo-hydraulic simulator (mock-up) for testing both traditional and innovative thermal energy measurement devices and heat cost allocators has been recently built up, in the context of the EU Seventh Framework Programme FP7-SME-2012. The INRiM mock-up is an automatically reconfigurable thermo-hydraulic circuit equi...

Challenges and opportunities:•Photocatalytic overall water splitting is an intriguing process to produce hydrogen. However, the photocatalytic efficiency unsatisfactory. Thus, it necessary analyze challenges for splitting.•The unfavorable thermodynamics, sluggish kinetics, dissolved oxygen, backward reaction, side reaction make enormously difficult. These obstacles must be overcome achieve in s...
