Simultaneous Detection of Steroid Esters and Multi‐Class Substances in Dried Blood Spots by LC‐HRMS/MS From a Single Spot for Human Doping Control

open access: yesDrug Testing and Analysis, EarlyView.
A validated LC‐HRMS/MS method enabled, for the first time, the comprehensive detection of steroid esters and multi‐class menu substances from a single dried blood spot. Following extraction, the resulting extract is split into two aliquots, reducing sample consumption and simplifying the analytical workflow.

Retrospective Study on the Power and Interpretation of Chiral Amphetamine Analysis in Hair for Forensic Applications

open access: yesDrug Testing and Analysis, EarlyView.
A decision model for the interpretation of chiral amphetamine analysis in hair was established based on the enantiomeric fraction (EF) of (S)‐amphetamine in authentic hair samples. Two chiral analysis methods (indirect/direct) were consecutively applied to distinguish between illicit and therapeutic amphetamine use in forensic cases.

Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

open access: yesEcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Revealing the Assembly Design of a BYD 46120 LFP Cylindrical Cell Through Systematic Teardown Analysis

open access: yesEcoEnergy, EarlyView.
The internal assembly design of a commercial BYD 46120 LFP cylindrical lithium‐ion battery was revealed through systematic mechanical teardown and multi‐scale analysis. Key features, including a tabless electrode architecture, engineered current‐collecting disks, separator‐core mandrel design, and electrolyte composition, are reconstructed to provide ...

Iron‐Catalyzed Hydrodecarboxylation of Fatty Acids From Vegetable Oils for Drop‐In Biofuel Production

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
An iron‐catalyzed hydrodecarboxylation for renewable hydrocarbon production is reported, featuring an alternative hydrogen source and a commercially available iron salt as the catalyst. The protocol enabled efficient one‐pot Cn–1 hydrocarbon synthesis from vegetable oils under mild and open‐air conditions.

Real‐world evaluation of capillary microsampling for drug monitoring of anti‐seizure medications

open access: yesEpilepsia, EarlyView.
Abstract Objective Capillary microsampling offers a minimally invasive alternative to venipuncture for therapeutic drug monitoring (TDM) of anti‐seizure medications (ASMs). We evaluated the feasibility and reliability of volumetric absorptive microsampling (VAMS) and quantitative dried blood spot (qDBS) devices for ambulatory self‐collection and at ...

Reversal of Chronic Stress‐Induced Inflammaging by Bazi Bushen Formula Through AMPK‐Sirtuins Axis Activation and Myeloid Reset

open access: yesExploration, EarlyView.
Chronic stressors trigger systemic immune remodeling marked by myeloid expansion and lymphoid suppression, and this immune imbalance subsequently drives tissue pathology through proinflammatory signaling and senescence amplification, with the lung and kidney confirmed as the most vulnerable target organs.
