No. 1
A ternary CsPbBr₃/graphene/Ag nanocomposite was fabricated by integrating laser direct writing with photo-induced synthesis, enabling in situ anchoring of both Ag nanoparticles and perovskite nanocrystals within a porous graphene framework. Photoluminescence spectroscopy revealed that graphene quenches the emission of pristine CsPbBr₃ nanocrystals via rapid hole–electron separation, while Ag addition modestly restores luminescence through surface plasmon resonance. For your theoretical work on energy nanomaterials, this platform demonstrates how controlled carrier dynamics and interfacial charge transfer can be engineered in perovskite–graphene systems for advanced photocatalytic and photoelectrochemical applications.

Drug-dependent modulation of micelle morphology and encapsulation in Triton X-100 systems
Molecular dynamics simulations reveal that drug-specific molecular features distinctly modulate the morphology and encapsulation efficiency of Triton X-100 micelles. The study demonstrates that small variations in drug chemistry produce quantifiable changes in micelle shape, size, and drug loading capacity, governed by specific interaction patterns between the drug and surfactant. For a theoretical chemist investigating nanomaterials for energy, this framework offers a transferable approach to modeling how molecular structure governs self-assembly and encapsulation in surfactant-based nanocarriers, with potential applications in controlled release and nanoreactor design.

[ASAP] High-Throughput Calorimetric Titration of Active Sites on Metal Oxide-Supported Catalysts with Infrared Thermal Imaging
A high-throughput method using infrared thermal imaging was developed to calorimetrically titrate active sites on metal oxide-supported catalysts, enabling rapid, parallel quantification of catalytic surface reactivity. This technique directly measures the heat released during probe-molecule adsorption, providing a direct readout of site density and distribution without the need for spectroscopic labels. For your research on energy materials, this experimental approach could be paired with theoretical models to predict and validate active site landscapes in heterogeneous catalysts for energy conversion.

Environmentally Friendly Waterborne Polymer/Reduced Graphene Oxide Nanocomposite Anticorrosion Coatings for Q235 Carbon Steel
A waterborne polymer/reduced graphene oxide nanocomposite was synthesized via miniemulsion polymerization, forming a defect-free anticorrosion coating on Q235 carbon steel without requiring chemical modification of the rGO filler. At pH 10, the coating exhibited a corrosion protection efficiency of 99% after 168 hours in saline solution, with an extremely low corrosion current density of 0.01 µA cm⁻². For your theoretical investigations of nanomaterials, this system demonstrates how polymer–graphene interfacial chemistry can be optimized to produce durable, solvent-free protective coatings with tunable electronic and mechanical properties.

Sheet-bundle interfacial synergy enhances hierarchical load-transfer and energy-dissipation in Graphene/CNT composite films
Hierarchical graphene/CNT composite films were shown to exhibit enhanced load-transfer and energy-dissipation properties through sheet-bundle interfacial synergy, as published in Composites Part A. The authors demonstrated that the nanoscale architecture between graphene sheets and carbon nanotube bundles creates multiple energy dissipation pathways that significantly improve mechanical toughness. For your work on energy nanomaterials, this hierarchical design principle offers a model system for understanding how interfacial engineering in nanocarbon assemblies can be leveraged to create mechanically robust conductive networks for energy storage and conversion devices.
