Researchers showed that point-defect engineering can control how copper nanoparticles exsolve from perovskite oxides, influencing exsolution yield, particle size, nucleation density, and anchoring. The study also found that oxygen vacancies are consumed during exsolution and that lattice strain can eventually limit further nanoparticle formation.
Researchers developed a high-throughput workflow that combined cryogenic spectroscopy, automated statistical analysis, and scanning transmission electron microscopy to link fabrication conditions and junction microstructure to the strongly coupled two-level system (TLS) density across about 6,000 Al/AlOx/Al Josephson junctions. They found that thicker aluminum electrodes and larger grains were associated with an approximately two-thirds lower detectable TLS density, while the precise microscopic cause remains unresolved.
Researchers developed a sacrificial-template porous silica thin film for electrochemically directed oligonucleotide synthesis that increased the available reaction area while preserving localized electrochemical control. The platform supported parallel synthesis of 121-nucleotide strands and recovery of an encoded 60-byte message, while highlighting remaining challenges in synthesis fidelity, parallelism, and cost.
Nanocoating technology reduces interfacial resistance between electrode and electrolyte, maximizing efficiency in both hydrogen production and power generation
Researchers developed an end-to-end inverse design method that uses LSTM prediction, a conditional generative adversarial network, and metasurface reconstruction to tailor the photon density of states in 3D photonic crystals made through holographic lithography. The method produced connected structures with strong local pDOS enhancement across multiple target frequencies and identified two recurring high-pDOS morphological families, while the reported optical gains remained computational rather than experimentally measured.
Polymer solar cells (PSCs) promise lightweight, flexible, and scalable solar energy, yet their efficiency still lags behind inorganic counterparts due to high exciton binding energy, low ambipolar carrier mobility, and substantial non-radiative recombination losses.
Most of today's computer chips — also sometimes known as conventional integrated circuits — use electrons to deliver their signals via semiconductor materials and metallic components. In contrast, photonic integrated circuits use faster signal carriers, such as photons or quantized "light particles."
Researchers engineered a stretchable pressure-sensitive composite that combines carbon nanofibers and carbon black nanoparticles in PDMS to tune sensitivity, sensing range, and resistance response. They integrated the material into flexible sensor arrays and paired it with circuit modeling and normalization to reduce crosstalk and track spatial pressure patterns and handwritten trajectories.
A comprehensive review identifies graphene dispersion, carbon-aluminum interface control, and manufacturing cost as major barriers to industrial-scale graphene/aluminum composites. The authors highlight controlled Al4C3 formation, graphene surface modification, and combinations of rapid solid-state processing with lower-cost casting as promising routes toward materials that retain mechanical, electrical, and thermal performance.
Placing two lattices - like window screens - on top of each other and twisting one layer compared to the other creates intriguing patterns. In fact, there are toys based on the designs that emerge, called moiré patterns.
