Microscopic Structure and Dynamics of Interfacial Water at Fluorinated vs Nonfluorinated Surfaces -- Insights from Ab-Initio Simulations and IR Spectroscopy

By combining large-scale ab-initio simulations with IR spectroscopy, this study reveals that while fluorinated surfaces exhibit macroscopic hydrophobicity, their interfacial water structure and slower reorientation dynamics are governed by dispersive rather than electrostatic interactions, resulting in unique spectroscopic signatures that defy simple classification as either hydrophobic or hydrophilic.

Strain-released epitaxy of GaN enabled by compliant single-crystalline metal foils

This paper demonstrates a novel strain-released epitaxy method for growing nearly strain-free single-crystalline GaN on compliant single-crystalline copper foils, where mismatch-induced stress is partitioned into the substrate via elastic deformation and localized interfacial slip, enabling high-performance GaN micro-LED arrays with efficient electrical and thermal properties.

Emergence of ferromagnetic state due to structural disorder in pseudo-binary Ce(Fe0.9Co0.1)2 compound

This study demonstrates that introducing structural disorder through rapid quenching and severe plastic deformation in the pseudo-binary Ce(Fe0.9Co0.1)2 compound stabilizes a low-temperature ferromagnetic state by suppressing the first-order transition to the antiferromagnetic phase, a mechanism attributed to topological disorder rather than simple structural distortions, which consequently significantly reduces the material's magnetocaloric entropy change.

Towards a unified first-principles-based description of VO2_2 using DFT+DMFT with bond-centered orbitals

This study employs a unified DFT+DMFT approach using bond-centered orbitals to comprehensively describe the structural and electronic properties of VO2_2 across its full phase space, revealing that the M2 phase is a strain-dependent local energy minimum featuring coupled singlet and Mott insulating states, while the T phase acts as a transitional state between M1 and M2 behaviors.

Efficient Picosecond-Laser Lift-Off of Copper Oxide from Copper: Modelling and Experiment

This paper establishes a theoretical framework and validates it experimentally to demonstrate that the optimal fluence for maximizing the lifted-off area in picosecond laser lift-off of copper oxide is F0opt=e1FthF_0^{\mathrm{opt}} = e^{1} F_{\mathrm{th}}, which is substantially lower than the fluence required for maximum ablation volume.

Importance of Electronic Entropy for Machine Learning Interatomic Potentials

This paper demonstrates that conventional machine learning interatomic potentials fail to accurately model mixed-valence materials like NaFePO4 due to their inability to capture electronic entropy, but introducing explicit charge-state information into the potential's representation successfully resolves these errors and enables correct structural optimization and thermodynamic predictions.

Role of a Quarter-Wave Plate in Confocal Microscopy: Signature of Spin-Orbit Interactions

This paper demonstrates that embedding a single quarter-wave plate in a confocal microscope induces strong spin-orbit interactions that transform a Gaussian beam into a tunable Hermite-Gaussian-like mode while significantly enhancing the polarization extinction ratio, offering a simple method for spatial mode engineering in standard optical systems.
