Molecular pH Probes [PDF]

open access: yesCirculation Research, 2006
See related articles, pages 501–509 and 510–519 Physiology is an old (some today may consider it an ancient) discipline. However, physiology is, at its core, the discipline that merges structure and function in biological organisms. Over the past 30 years, as technology has advanced, the discipline has gravitated to smaller and smaller systems ...

Visible Photocatalytic Hydrogen Evolution by g-C3N4/SrZrO3 Heterostructure Material

open access: yesNanomaterials, 2023
A heterostructure material g-C3N4/SrZrO3 was simply prepared by grinding and heating the mixture of SrZrO3 and g-C3N4. The morphology and structure of the synthesized photocatalysts were determined by scanning electron microscopy (SEM), X-ray diffraction

Photocatalytic Overall Water Splitting by SrTiO3 with Surface Oxygen Vacancies

open access: yesNanomaterials, 2020
Strontium Titanate has a typical perovskite structure with advantages of low cost and photochemical stability. However, the wide bandgap and rapid recombination of electrons and holes limited its application in photocatalysis.

Grey Rutile TiO2 with Long-Term Photocatalytic Activity Synthesized Via Two-Step Calcination

open access: yesNanomaterials, 2020
Colored titanium oxides are usually unstable in the atmosphere. Herein, a gray rutile titanium dioxide is synthesized by two-step calcination successively in a high-temperature reduction atmosphere and in a lower-temperature air atmosphere.

Charge-Shift Bonding Propensity in Halogen-Bonded BXY (B Is a Small Lewis Base H2O or NH3; X and Y Are Halogen Atoms) Complexes: An NBO/NRT/AIM Investigation

open access: yesMolecules, 2023
Charge-shift (CS) bonding is a new bonding paradigm in the field of chemical bonds. Our recent study has revealed that certain Cu/Ag/Au-bonds display both CS bonding and ω-bonding characters. In this investigation, we extend our study to halogen bonding.

Masers: Precision probes of molecular gas [PDF]

open access: yesAdvances in Space Research, 2020
Maser emission from water, methanol, silicon monoxide and other molecules can reach brightness temperatures ≫1010 K. Such observations can achieve sub-pc precision for discs around black holes or sub-au scale interactions in protostellar discs and the regions where evolved star winds reach escape velocity.
