Effect of Water on Local Structure and Dynamics in a Protic Ionic Liquid‐Based Electrolyte

ChemSusChem, EarlyView.
Small, short‐lived, water clusters enhance ionic dynamics on the molecular scale and increase the macroscopic ionic conductivity in diluted protic ionic liquids. Ionic liquids (ILs) are promising candidates for electrolytes for next‐generation energy storage and conversion systems.

Advanced Characterization of Lignin Nanoparticles by Asymmetric Flow‐Field Flow Fractionation

ChemSusChem, EarlyView.
Enhanced particle size distributions of lignin nanoparticles – including samples that contain aggregates or consist of multiple size populations – by asymmetric flow field‐flow fractionation hyphenated with multi angle laser light scattering (MALLS), dynamic light scattering (DLS) and refractive index (RI) detection.

Rapid and Effective Determination of Ethyl Glucuronide in Hair by Micro Extraction by Packed Sorbent (MEPS) and LC‐MS/MS

Drug Testing and Analysis, EarlyView.
The development and validation of a MEPS method for the purification of hair extract for the EtG determination and quantification in the keratin matrix is the main focus of this study. The method is fast and effective and, as a miniaturised technique, requires only small amounts of solvent.

β‐Hydroxy β‐Methyl Butyric Acid (HMB) and Its Potential Doping Relevance: A Pilot Study on Its Urinary Excretion Profile

Drug Testing and Analysis, EarlyView.
β‐hydroxy β‐methyl butyric acid (HMB), either as the free acid or in the form of its calcium salt, is a component of several dietary supplements marketed to enhance sports performance. We investigated the urinary excretion profile of HMB, also assessing the endogenous reference ranges of HMB in human urine samples from healthy volunteers (n = 20). Data

Solvation chemistry in liquid electrolytes for rechargeable lithium batteries at low temperatures

EcoEnergy, EarlyView.
This review discusses the solvation chemistry of the electrolyte in lithium batteries (LBs) at low temperature (LT). It highlights the Li+ solvation chemistry in LBs at LT, including the properties of the solvent, the solvation structure of Li+, strategies of tuning solvation chemistry via solvents/lithium salts, and characterization techniques of ...

Unveiling the Formation and Electrochemical Properties of Nano‐Clusters in Lithium Battery Electrolyte Induced by Nitrate Ion

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The combination of molecular dynamics and spectra analysis unveils that the addition of LiNO3 can largely increase the average size of Li+‐solvation structures with the formation of nanoclusters, which are endowed with intrinsically narrow energy levels and contribute to the formation of a stable electrode/electrolyte interphase for lithium metal ...

T1 mapping and major cardiovascular events in non‐ischaemic dilated cardiomyopathy: a systematic review and meta‐analysis

ESC Heart Failure, EarlyView.
In NIDCM patients, native T1 mapping and ECV were associated with increased risk of the composite primary endpoint of MACE and the secondary endpoint of heart failure and arrhythmic‐related events. Patients who experienced MACE had higher values of both T1 mapping and ECV.

Spatial Reconstruction of Pore‐Crack Microstructure and Its Topological Configuration Relationship With Connectivity and Pore‐Scale Flow in Coal by 3D‐XRM

Energy Science &Engineering, EarlyView.
ABSTRACT In consideration of the significance of connectivity features and topological relationships within the pore‐crack network, the micro‐scale pore‐crack microstructure of intact and tectonic coals from Qinan was investigated in 3D spatial visualization using digital core technology.

Abstract Conformer Space

Helvetica Chimica Acta, Accepted Article.
Pairwise distance root mean square deviation defines a hyperspace where conformers with similar shape reside close to each other. The radius of gyration of protein ensembles in this abstract conformer space (ACS) converges at ensemble sizes between 50 and 500, depending on the extent of disorder.
