Archaeometry, EarlyView.ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Non‐canonical PKG1 regulation in cardiovascular health and disease
British Journal of Pharmacology, EarlyView.It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

Comparison of models for H2–H2 and H2–He anisotropic intermolecular repulsion
The Journal of Chemical Physics, 1977Three empirical potential models (dumbbell, Kihara, and ellipsoidal overlap) are fitted to theoretical calculations of H2–H2 and H2–He repulsion. The dumbbell model gives a slightly better fit and has better transferability. This model is recommended because of its simplicity and physical meaningfulness.

Interaction Energies for the H–H2 and H2–H2 System
The Journal of Chemical Physics, 1960Interaction energies for the H–H2 and H2–H2 systems have been obtained by a semiempirical perfectpairing procedure used previously. The results have been compared with interaction energies obtained from other sources and the agreement among the different curves is reasonably good.

International Journal of Hydrogen Energy, 1982
Abstract Preferable conditions for the thermal decomposition of hydrogen sulfide, one step in thermochemical water splitting cycles of metal-sulfur families, are described. To separate hydrogen from hydrogen sulfide after condensation of sulfur a pressure swing adsorption on zeolite or carbon molecular sieves is proposed which may also be suitable ...

Floating Wave Functions for H2+ and H2
The Journal of Chemical Physics, 1958Floating wave functions using ordinary 1s orbitals are reexamined for both H2+ and H2. Results previously reported in the literature are found to be in error. The newly obtained energies are disappointingly high. It is conjectured that these relatively poor energies are largely the result of the inability of this kind of approximation to give a good ...

Catalytic transformation of H2S for H2 production
International Journal of Hydrogen Energy, 2018Abstract Hydrogen sulfide (H2S) gas is a by-product from natural gas refining, hydrodesulfurization of various fossil fuels, and syngas cleaning from pyrolysis and gasification. Catalytic pyrolysis of H2S provides an alternative and effective pathway to recover both H2 and sulfur.

Vibrational polarizabilities for H2+, H2 and N2
Chemical Physics Letters, 1987Abstract General formulae for the purely vibrational contributions to the static polarizabilities Aα,βγ, Bα,β,γδ,and Cαβ,γδ are presented. As specific examples, the vibrational contributions to the γ, B, and C tensors for H2+, H2 and N2 are calculated.

Numerical Calculation of H2+ and H2 Wavefunctions
The Journal of Chemical Physics, 1964A numerical method of calculation, involving Gauss quadratures in four dimensions, is proposed for diatomic molecule calculations. It is applied to a linear variation function for H2+ and to James—Coolidge-type correlated functions for H2 with up to 15 basis functions.
