The naturally occurring peptide indolicidin from bovine neutrophils exhibits strong biological activity against a broad spectrum of microorganisms. This is believed to arise from selective interactions with the negatively ...

This work demonstrates how a multi-electrode array (MEA) dedicated to four-electrode bioimpedance measurements can be implemented on a complementary metal–oxide–semiconductor (CMOS) chip. As a proof of concept, an 8 × 8 ...

The design of a time-of-flight neutron reflectometer proposed for the new generation of compact neutron sources is presented. The reflectometer offers the possibility to use spin-polarized neutrons. The reflectometer design ...

Phosphoramides are an interesting alternative to the thiourea motif that has long been used in organocatalysis. In the R1N(H)-P(O)(R3)-N(H)R2 formulation, phosphoramides give the advantage of having a third variable ...

ABSTRACT Magnetic white dwarfs with field strengths below 10 MG are easy to recognize since the Zeeman splitting of spectral lines appears proportional to the magnetic field strength. For fields ≳100 MG, however, transition ...

The catalytic mechanism of the cyclic amidohydrolase isatin hydrolase depends on a catalytically active manganese in the substrate-binding pocket. The Mn2+ ion is bound by a motif also present in other metal dependent ...

Abstract A common challenge when studying rare diseases or medical conditions is the limited number of patients, usually resulting in long inclusion periods as well as unequal sampling and storage conditions. The main ...

Abstract The use of diaryliodonium salts in organic reactions has rapidly increased in the last decade because of their efficiency in arylation reactions. Despite this, mechanistic investigations are still scarce, particularly ...

Proton-transfer-reaction mass spectrometry (PTR-MS) is seeing an increased use of NH4+ ions for the detection of amines and labile oxygenated organic compounds. NH4+ ions are usually generated from ammonia or ammonium-containing ...

Molecular structure, a key concept of chemistry, has remained elusive from the perspective of all-particle quantum mechanics despite many efforts. Viewing molecular structure as a manifestation of strong statistical ...
