Redox Potential and Crystal Chemistry of Hexanuclear Cluster Compounds

open access: yesMolecules, 2021
Most of TM6-cluster compounds (TM = transition metal) are soluble in polar solvents, in which the cluster units commonly remain intact, preserving the same atomic arrangement as in solids.

Metal–Metal Bond in the Light of Pauling’s Rules

open access: yesMolecules, 2021
About 70 years ago, in the framework of his theory of chemical bonding, Pauling proposed an empirical correlation between the bond valences (or effective bond orders (BOs)) and the bond lengths.

Geometric and energetic data from quantum chemical calculations of halobenzenes and xylenes

open access: yesData in Brief, 2020
This article presents theoretical data on geometric and energetic features of halobenzenes and xylenes. Data were obtained from ab initio geometry optimization and frequency calculations at HF, B3LYP, MP2 and CCSD levels of theory on 6–311++G(d,p) basis ...

Sea Level Seasonal, Interannual and Decadal Variability in the Tropical Pacific Ocean

open access: yesRemote Sensing, 2021
The satellite altimeter data, temperature and salinity data, and 1.5-layer reduced gravity model are used to quantitatively evaluate the contributions of the steric effect and the dynamic process to sea level variations in the Tropical Pacific Ocean (TPO)

Steric Effects on Electroosmotic Nano-Thrusters under High Zeta Potentials

open access: yesMathematics, 2021
Here, space electroosmotic thrusters in a rigid nanochannel with high wall zeta potentials are investigated numerically, for the first time, considering the effect of finite size of the ionic species. The effect, which is called a steric effect, is often

Steric and Stereochemical Modulation in Pyridyl- and Quinolyl-Containing Ligands

open access: yesMolecules, 2016
Nitrogen-containing pyridine and quinoline are outstanding platforms on which excellent ionophores and sensors for metal ions can be built. Steric and stereochemical effects can be used to modulate the affinity and selectivity of such ligands toward ...

Kinetics of the reaction of 5-substituted orotic acids with diazodiphenylmethane [PDF]

open access: yesJournal of the Serbian Chemical Society, 2004
Rate konstants for the reaction of eight 5-substituted orotic acids with diazodiphenylmethane (DDM) in dimethylformamide (DMF) were determined at 30 ºC by the known spectrophotometricmethod.

Outlining the Roles of Membrane-Foulant and Foulant-Foulant Interactions in Organic Fouling During Microfiltration and Ultrafiltration: A Mini-Review

open access: yesFrontiers in Chemistry, 2020
Membrane fouling remains a notorious problem in microfiltration (MF) and ultrafiltration (UF), and a systematic understanding of the fouling mechanisms is fundamental for solving this problem. Given a wide assortment of fouling studies in the literature,
