Enhanced Thermoelectric Performance of GeTe‐Sb2Te3 Pseudo‐Binary Phase Change Material Through Stoichiometry Optimization

Advanced Electronic Materials, EarlyView.
A GeTe‐Sb2Te3 composition spread is fabricated using RF magnetron co‐sputtering. Increasing Sb content stabilized the high‐performance cubic GeTe phase. The composition 5Sb3₇Te5₈ exhibited the highest thermoelectric performance, achieving a power factor of ∼1 mW m−1 K−2 and a maximum zT of 0.81 at 300°C.

Engineering Na‐Rich P2‐Type Layered Oxides Through Li/Ti Dual Doping for Oxygen Redox Activation and Superior Structural Stability

Advanced Energy Materials, EarlyView.
P2‐type sodium layered oxides have potential for high‐voltage operation but suffer from structural instability and capacity fading. This work demonstrates that synergistic Li and Ti co‐doping enhances sodium inventory, suppresses detrimental phase transitions, and activates reversible lattice oxygen redox.

Decoupling Chemical and Mechanical Contributions to Capacity Fading in Ni‐Rich Cathodes for Sulfide‐Based All‐Solid‐State Batteries

Advanced Energy Materials, EarlyView.
Ni‐rich cathodes in sulfide‐based ASSBs undergo intertwined (electro)chemical and mechanical degradation. Here, a new diagnostic framework is presented to decouple each contribution by partitioning capacity fading into charge and discharge fading.

Electron Donor–Acceptor Complex Catalysis in Synthetic Chemistry

Angewandte Chemie, EarlyView.
Electron donor–acceptor (EDA) complexes are moving beyond stoichiometric photoactivation toward catalytic platforms for radical generation. Productive EDA catalysis requires coordinated donor–acceptor association, charge‐transfer excitation, radical reactivity, and vcatalyst turnover.

3D Printed Ordered Porous Architectures of Functional Metal Tellurides for Ultra High Mass‐Loaded Ammonium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Aqueous ammonium‐ion batteries (AAIBs) are emerging as promising alternatives for next‐generation energy storage. To overcome the limited ion diffusion associated with ultrahigh mass‐loading electrodes, this work develops a 3D‐printed porous conductive electrode of metal‐telluride fabricated via selective laser melting technique.

Ligand‐Directed Molecular Beacons as Turn‐On Fluorescent Probes for Sensing Cell‐Surface Receptor‐Ligand Interactions

Angewandte Chemie, EarlyView.
Multivalent, ligand‐directed molecular beacons enable fluorescence turn‐on detection of cell‐surface receptors in living cells. The probes strongly engage closely spaced membrane receptors and exhibit conformation‐dependent fluorescence enhancement at the cell surface, enabling wash‐free receptor imaging, inhibitor screening, and functional evaluation ...

Minimal Migration Virtual Machine (VM) Selection Algorithm in Dynamic VM Consolidation

Virtual machine consolidation in cloud data centers is a strategy to optimize the utilization of physical server resources. Virtual machine consolidation involves the migration of virtual machines from the overloaded and under loaded hosts. Planning the migration of virtual machines involve the decision of virtual machine selection and placement.

Machine learning–driven design of catalytic processes for sulfur dioxide oxidation: Lessons from the trenches

AIChE Journal, EarlyView.
Abstract Despite the growing use of ML in chemical engineering, the catalytic conversion of sulfur dioxide (SO2) to sulfur trioxide (SO3) remains underexplored from a data‐driven modeling perspective. This study evaluates an integrated workflow for literature‐derived SO2 oxidation data, combining data curation, preprocessing assessment, machine ...

Sustainable Access to N‐Heterocycles: One‐Pot Cascade Synthesis of Pyrroles From Bio‐Derived Furans

Angewandte Chemie, EarlyView.
Highly dispersed platinum (Pt) clusters on Brønsted acid‐rich HY zeolite enable a one‐pot cascade conversion of bio‐derived furans and nitroarenes into pyrroles. Highly dispersed Pt sites ensure selective nitro hydrogenation, while Pt nanoparticles promote undesired over‐hydrogenation.
