Accelerating SCF Convergence Through Equivariant Density‐Matrix Learning and Analytic Refinement

Chemistry – A European Journal, EarlyView.
Machine learning predicts physically consistent one‐electron reduced density matrices that provide efficient initial guesses for self‐consistent field calculations. Across diverse molecular systems, this warm‐start strategy reduces the required self‐consistent‐field (SCF) iterations by up to 80% while preserving converged energies and atomic forces ...

An Investigation Into the Yields of 3,4‐Methylenedioxyphenyl‐2‐propanone (MDP2P) From Glycidate Pre‐Precursors

Drug Testing and Analysis, EarlyView.
Hydrolysis of the glycidate pre‐precursors MMDMG and EMDMG was evaluated for MDP2P production. Acid hydrolysis of MMDMG (HCl, 100°C, 18 h) yielded the highest MDP2P recovery (79%), whereas base hydrolysis produced only slightly lower yields (73%), demonstrating both pathways are effective routes to this key MDMA precursor.

Population Pharmacokinetics and Detection Times of Betamethasone After Intravenous, Intramuscular, and Intranasal Jet Administration of Betamethasone Sodium Phosphate in Horses

Drug Testing and Analysis, EarlyView.
Betamethasone concentrations in 20 horses from Japan and Germany following IV, IM, and INJ administration of betamethasone phosphate were analyzed using population pharmacokinetic modeling. For IV administration of 0.04 mg/kg q24 h, IPC and IUC were 0.012 and 0.31 ng/mL, respectively; the IUC approximated the IFHA urine ISL (0.20 ng/mL).

Phase‐Change‐Activated Slippery Organogel Composite for All‐in‐One Anti‐Corrosion, Antifouling, and Self‐Cleaning

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A super‐slippery liquid‐infused composite organogel is engineered by localized interfacial grafting between hydrogel and oleogel networks, endowing the coating with a durable, multifunctional marine‐protective interface. Dynamic antifouling surfaces have emerged as a promising alternative, offering the potential for eco‐friendly and high‐performance ...
