Steric Effects and Solvent Effects in Ionic Reactions
, 2002 Rates of S N 2 reactions of chloride ion with methyl- and tert -butyl–substituted chloroacetonitrile were measured by using Fourier transform–ion cyclotron resonance spectrometry to follow the ...

Steric effects in cyclization reactions
, 1976 Calculations of geometric probability factors indicate that steric effects are important in determining whether the cyclization of β-substituted diallylmethylammonium ions results in five- or six-memberedrings.

Molecules, 2023 A density functional theory (DFT) study combined with the steric maps of buried volume (%VBur) as molecular descriptors and an energy decomposition analysis through the ASM (activation strain model)–NEDA (natural energy decomposition analysis) approach ...

Poisson-Fermi Formulation of Nonlocal Electrostatics in Electrolyte Solutions
Computational and Mathematical Biophysics, 2017 We present a nonlocal electrostatic formulation of nonuniform ions and water molecules with interstitial voids that uses a Fermi-like distribution to account for steric and correlation efects in electrolyte solutions.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Sea-level trend variability in the Mediterranean during the 1993–2019 period
Frontiers in Marine Science, 2023 Sea-level change is one of the most concerning climate change and global warming consequences, especially impacting coastal societies and environments. The spatial and temporal variability of sea level is neither linear nor globally uniform, especially ...

Steric Effects in e-N2 Scattering
, 1995 Steric effects in collisions between electrons and ensembles of free diatomic molecules with an arbitrary axis distribution are investigated. A general expression for the angular distribution of the scattered projectiles is derived where the factors ...

Structure‐forward targeting of claudins with synthetic binders
FEBS Letters, EarlyView.Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Steric effects on reactivity in some naphthalene derivatives [PDF]
, 1957 In order that a better understanding of the relative reactivity of α- and β-naphthalene derivatives be attained, two approaches have been made to evaluate the magnitude of steric effects associated with some α-naphthalene derivatives.
