CORRELATION ANALYSIS OF IR, 1 H- AND 13 C-NMR SPECTRAL DATA OF N-ALKYL AND N-CYCLOALKYL CYANOACETAMIDES [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2011
Linear free energy relationships (LFER) were applied to the IR, 1H- and 13C--NMR spectral data in N-alkyl and N-cycloalkyl cyanoacetamides. N-alkyl and N-cycloalkyl cyanocetamides were synthesized from corresponding amine and ethyl cyanoacetate. A number

An Atomically Dispersed Photocatalyst for Undirected para‐Selective C─H Bond Functionalizations

open access: yesAngewandte Chemie, Volume 137, Issue 33, August 11, 2025.
This study presents an atomically dispersed recyclable heterogeneous photocatalytic method for para‐selective trifluoromethylation of electron‐deficient arenes without directing groups. Unlike previous substrate‐dependent approaches, this recyclable, atomically dispersed photocatalyst enables scalable synthesis of bioactive trifluoromethylated ...

The Importance of Developmental Science for Studies in Bullying and Victimization [PDF]

open access: yes, 2012
Research on bullying and victimization, especially in school settings, has become an important area of developmental research, with strong practical implications. In this article we overview some considerations from neuropsychology, quantitative genetics,

Comparison of lipid membrane-water partitioning with various organic solvent-water partitions of neutral species and ionic species: Uniqueness of cerasome as a model for the stratum corneum in partition processes [PDF]

open access: yes, 2015
YesLipid membrane-water partitions (e.g., immobilized artificial membrane systems where the lipid membrane is a neutral phospholipid monolayer bound to gel beads) were compared to various organic solvent-water partitions using linear free energy ...

Contrasting Historical and Physical Perspectives in Asymmetric Catalysis: ΔΔG≠ versus Enantiomeric Excess

open access: yesAngewandte Chemie, Volume 136, Issue 48, November 25, 2024.
We explore the difference between enantiomeric excess (ee) and relative Gibbs free activation energies (ΔΔG≠) as modeling targets in asymmetric catalysis. Through data analysis and application of modern machine learning methods, we unveil the strengths and limitations of each approach.

An Equation for the Prediction of Human Skin Permeability of Neutral Molecules, Ions and Ionic Species [PDF]

open access: yes, 2017
yesExperimental values of permeability coefficients, as log Kp, of chemical compounds across human skin were collected by carefully screening the literature, and adjusted to 37 °C for the effect of temperature.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Interplay between partner and ligand facilitates the folding and binding of an intrinsically disordered protein. [PDF]

open access: yes, 2014
Protein-protein interactions are at the heart of regulatory and signaling processes in the cell. In many interactions, one or both proteins are disordered before association.
