Halogen Bonding in Sulphonamide Co-Crystals: X···π Preferred over X···O/N?

open access: yesMolecules, 2023
Sulphonamides have been one of the major pharmaceutical compound classes since their introduction in the 1930s. Co-crystallisation of sulphonamides with halogen bonding (XB) might lead to a new class of pharmaceutical-relevant co-crystals. We present the

Nonempirical Range-separated Hybrid Functionals for Solids and Molecules [PDF]

open access: yes, 2016
Dielectric-dependent hybrid (DDH) functionals were recently shown to yield accurate energy gaps and dielectric constants for a wide variety of solids, at a computational cost considerably less than that of GW calculations.

Evolution of the Immunoglobulin Isotypes—Variations of Biophysical Properties among Animal Classes

open access: yesBiomolecules, 2023
The adaptive immune system arose around 500 million years ago in jawed fish, and, since then, it has mediated the immune defense against pathogens in all vertebrates.

The Extraction of Community Structures from Publication Networks to Support Ethnographic Observations of Field Differences in Scientific Communication [PDF]

open access: yes, 2013
The scientific community of researchers in a research specialty is an important unit of analysis for understanding the field specific shaping of scientific communication practices. These scientific communities are, however, a challenging unit of analysis

Impact of peanut shells, olive pomace, and plaster on the dielectric properties of PA6

open access: yesChemical Physics Impact, 2023
Polyamide 6 (PA6) is among the most widely used technical polymers due to its excellent balance between performance and cost. The diversity of its applications reflects its main qualities (good mechanical properties, thermal stability, resistance to many

Synthesis and characterization of hybrid organic-inorganic materials based on sulphonated polyamideimide and silica [PDF]

open access: yes, 2010
The preparation of hybrid organic–inorganic membrane materials based on a sulphonated polyamideimide resin and silica filler has been studied. The method allows the sol–gel process to proceed in the presence of a high molecular weight polyamideimide,

Structural Basis of the Immunological Cross-Reactivity between Kiwi and Birch Pollen

open access: yesFoods, 2023
Allergies related to kiwi consumption have become a growing health concern, with their prevalence on the rise. Many of these allergic reactions are attributed to cross-reactivity, particularly with the major allergen found in birch pollen.

Density functional theory in transition-metal chemistry: a self-consistent Hubbard U approach

open access: yes, 2006
Transition-metal centers are the active sites for many biological and inorganic chemical reactions. Notwithstanding this central importance, density-functional theory calculations based on generalized-gradient approximations often fail to describe ...
