Carbon 1s binding energy and substituent effects in C-centered radical cations

It was established for the first time that E b values in carboncentered radical cations depend on the inductive, resonance, and polarizability effects of substituents.

Changes in the composition of the solvation shell of lithium ions in γ-butyrolactone upon addition of 15-crown-5 as studied by quantum chemistry

Quantum chemical modeling of Li+ ion transfer from the solvation shell of ?-butyrolactone (GBL) as the solvent to the cavity of 15-crown-5 (15C5) macrocyclic ligand was carried out.

A mechanism of addition of a new aromatic electrophile, nitrobenzofuroxan, to cyclopentadiene

The reaction mechanisms of cycloaddition of nitrobenzofuroxan to cyclopentadiene are studied using DFT calculations at the B3LYP/6-31G* level in the gas phase and with account of the solvation effects.

Microbial selectivity on mineral surfaces: possible implications for weathering processes

In order to understand how microorganisms influence mineral surface processes, a better assessment of how microorganisms colonise mineral surfaces in situ is necessary. A crucial question in understanding mineral?

The role of fungi in biogenic weathering in boreal forest soils

In this article we discuss the possible significance of biological processes, and of fungi in particular, in weathering of minerals. We consider biological activity to be a significant driver of mineral weathering in forest ecosystems.

Scale matters? Exploring the effect of scale on fungal–mineral interactions

Oxalate is considered to be an important fungal weathering agent, but measured bulk soil concentrations in boreal forest soils are too low to expect a significant effect on mineral dissolution.

Aging in the Cold

Abstract The proposition that increased energy expenditure shortens life has a long history. The rate‐of‐living theory (Pearl 1928) states that life span and average mass‐specific metabolic rate are inversely proportional.
