Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This paper develops and numerically solves a dislocation pile-up model to predict how residual stress gradients in thin films evolve based on the film's thickness-to-width ratio and initial stress distribution, revealing that equilibrium requires a mixed population of dislocations with both positive and negative Burgers vectors.
This study utilizes in situ low-dose scanning electron diffraction to reveal that the dehydration of theophylline monohydrate proceeds via a two-step, reconstructive topotactic pathway involving anisotropic surface mass loss followed by localized nucleation of anhydrous form II, thereby demonstrating how surface-controlled dynamics govern solid-state phase transformations in molecular hydrates.
By combining lattice Boltzmann simulations and confocal microscopy experiments, this study reveals six distinct particle removal scenarios driven by the complex interplay of capillary and friction forces, introducing a dimensionless parameter to predict removal efficiency and guide the design of water- and chemical-efficient self-cleaning surfaces.
This study demonstrates that while microstructural heterogeneity in grain geometry has a modest effect, a broad distribution of grain-boundary viscosities can suppress and broaden the characteristic Debye-like peak of elastically accommodated grain-boundary sliding into a weak background, thereby explaining the absence of a pronounced peak in dry olivine experiments without negating the mechanism's relevance to upper-mantle seismic attenuation.
Using in situ STEM heating with MEMS technology, this study provides direct nanoscale observation of melting and solute redistribution in a hypoeutectic Al-Cu alloy, revealing that melting initiates at Cu-enriched grain boundaries, the AlCu phase melts before the matrix, and liquid-state Cu redistribution extends over 258 micrometers, far exceeding solid-state diffusion limits.
This study investigates how irradiating epitaxial thin films with a focused He ion beam induces lattice expansion, reduces the critical temperature, and drives a transition to an insulating state, thereby demonstrating a powerful technique for fabricating superconducting nano-devices with controlled structural and transport properties.
This paper demonstrates that reversible uniaxial strain can precisely and elastically control the doping and bandgap of suspended single-wall carbon nanotube quantum dots through quantum transport straintronics, offering a capacitive-free mechanism for applications in qubits and molecular transistors.
This paper presents a thermodynamically consistent phase field model that simulates hydrogen-assisted cracking in polycrystalline materials by coupling crack propagation with hydrogen segregation and interfacial energy reduction, successfully capturing the transition from transgranular to intergranular failure under hydrogen-enhanced decohesion mechanisms.
This paper generalizes the Multipole-Padé approximant framework to create a compact, symmetry-conserving, and anisotropic representation of the inverse dielectric function for 2D metals, enabling efficient and accurate calculation of plasmonic properties and correlation energies across the full Brillouin zone while bridging *ab initio* calculations with analytical models.
This paper introduces a crosstalk-suppressed SPAD-array photon-correlation method to quantify multi-photon emission in over 1,000 colloidal quantum shells, revealing a near-Gaussian distribution of biexciton emission efficiencies and confirming that intra-batch correlations with particle brightness align with volume-scaling Auger quenching.
