Transferable diamond tapes for decoupling diamond growth from metal protection

This paper introduces a transferable diamond tape strategy that decouples diamond growth from metal substrates by growing polycrystalline diamond on a releasable TiO₂ nanorod-engineered silicon template and attaching it to Ti6Al4V via a TiO₂ sol-gel adhesive, thereby creating a hierarchical, wear- and corrosion-resistant protective layer that reduces wear rates by four orders of magnitude and significantly lowers corrosion current density.

On the question of the zwitterionic intermediate in the (3+2) cycloaddition between 2-diphenylphosphinoyl-2-methyl-3,4-dihydro-2H-pyrrole N-oxide and di-t-butyl selenoketone: DFT mechanistic study

This DFT study challenges the hypothesis of a zwitterionic intermediate in the (3+2) cycloaddition between 2-diphenylphosphinoyl-2-methyl-3,4-dihydro-2H-pyrrole N-oxide and di-t-butyl selenoketone by demonstrating that while a two-step pathway is possible, it is less favorable than the kinetically preferred route that explains the observed regio- and stereoselectivity.

Machine Learning Offers No Advantage over the Garofalo–Arrhenius Model for Peak Flow Stress Prediction in Hot Torsion of AA6061-T6: A Single-Source Benchmarking Study

This study demonstrates that for small, well-characterized, single-source datasets of AA6061-T6 hot torsion, the classical Garofalo–Arrhenius constitutive model performs as accurately as and is statistically indistinguishable from advanced machine learning regressors, challenging claims of ML superiority in such contexts.

Modification of H3PO4-activated Pomelo Peel Biochar with Cetyltrimethylammonium Bromide for Methyl Orange Removal: Adsorption Performance and Mechanism

This study demonstrates that modifying H3PO4-activated pomelo peel biochar with 2 wt% cetyltrimethylammonium bromide (CTAB) significantly enhances its specific surface area and creates a positively charged surface, resulting in a highly effective adsorbent (CTAB2@A-PBC) capable of removing methyl orange with a maximum capacity of 534.23 mg/g through mechanisms including electrostatic attraction, pore-filling, π-π interactions, and hydrogen bonding.
