The spectrum and wave functions of 44 Ti are studied in oblique-basis calculations using spherical and SU(3) shell-model states. Although the results for 44 Ti are not as good as those previously reported for 24 Mg, due primarily to the strong spin-orbit interaction that generates significant splitting of the single-particle energies that breaks the SU(3) symmetry, a more careful quantitative a...

Porous BiVO4 electrodes were conformally decorated with CdS via a chemical bath deposition process. The highest photocurrent at 1.1 V vs. RHE was achieved for BiVO4/CdS composite (4.54 mA cm−2), compared (1.19 cm−2) and bare (2.1 under AM 1.5G illumination. This improvement in the photoefficiency can be ascribed to both enhanced optical absorption properties charge separation due heterojunction...

The sluggish kinetics of the oxygen evolution reaction (OER) is bottleneck for practical exploitation water splitting. Here, potential a core–shell structure hydrous NiMoO4 microrods conformally covered by Co3O4 nanoparticles via atomic layer depositions demonstrated. In situ Raman and synchrotron-based photoemission spectroscopy analysis confirms leaching out Mo facilitates catalyst reconstruc...

Theoretical studies have been carried out to investigate the unusual reactivity of Ag15 + cations with oxygen. Our previous work has shown that the reactivity of free metal clusters with oxygen entails a spin excitation that causes reduced reactivity in clusters with filled electronic shells and large HOMO-LUMO gaps. Earlier experiments on Ag15 + have shown that the cluster exhibits remarkable ...

Abstract—This work reports the potential of using Palm Kernel (PK) ash and shell as a partial substitute for Portland Cement (PC) and coarse aggregate in the development of mortar and concrete. PK ash and shell are agro-waste materials from palm oil mills, the disposal of PK ash and shell is an environmental problem of concern. The PK ash has pozzolanic properties that enables it as a partial r...
