Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

open access: yesAdvanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Determination of Enantiomers of Deschloroketamine and Its Metabolites in Wistar Rat Brains. [PDF]

open access: yesJ Sep Sci
Although supercritical fluid chromatography coupled to mass spectrometry efficiently resolved deschlorketamine and its metabolites, the parent drug must have been quantified by capillary zone electrophoresis. ABSTRACT Deschloroketamine (DXE) is a dissociative new psychoactive substance whose enantiomers and metabolites may exhibit distinct ...

Chiral separation of enantiomers of amino acid derivatives by high-performance liquid chromatography on a norvancomycin-bonded chiral stationary phase

open access: yes, 2004
A novel norvancomycin-bonded chiral stationary phase (NVC-CSP) was synthesized by using the chiral selector of norvancomycin. The chiral separation of enantiomers of several dansyl-amino acids by high-performance liquid chromatography (HPLC) in the ...

Multicritical matrix models and the chiral phase transition [PDF]

open access: yes, 1998
Universality of multicritical unitary matrix models is shown and a new scaling behavior is found in the microscopic region of the spectrum, which may be relevant for the low energy spectrum of the Dirac operator at the chiral phase ...

Evolutionary, Functional and Mechanistic Characterisation of Microbial Terpene Synthase‐Like Genes From Springtails

open access: yesAngewandte Chemie International Edition, EarlyView.
A genome analysis revealed the presence of many bacterial‐type terpene synthases in springtails. Four enzymes from Sinella curviseta were functionally characterised, resulting in the isolation of several compounds including sinellene ether, the first diterpene ether identified from a terpene synthase that represents a novel skeleton.

Preparation and evaluation of a novel chiral stationary phase based on covalently bonded chitosan for ligand-exchange chromatography

open access: yes, 2006
A novel chiral stationary phase based on chitosan covalently bonded onto silica gels has been prepared and used for the separation of various alpha-amino acid enantiomers as well as alpha-hydroxycarboxylic acid enantiomers by chiral ligand-exchange ...

The baryonic phase in holographic descriptions of the QCD phase diagram

open access: yes, 2012
We study holographic models of the QCD temperature-chemical potential phase diagram based on the D3/D7 system with chiral symmetry breaking. The baryonic phase may be included through linked D5-D7 systems. In a previous analysis of a model with a running

Preparation and evaluation of a vancomycin-immobilized silica monolith as chiral stationary phase for CEC

open access: yes, 2007
Enantiomeric separations in CEC with the macrocyclic antibiotic vancomycin immobilized silica monolith as a chiral stationary phase are presented. The monolithic silica capillary columns were prepared by a sol-gel process in fused-silica capillaries with
