We investigated the effects of cubic and quartic anharmonicity on lattice dynamics thermal transport in highly anharmonic ${\mathrm{BaZrO}}_{3}$ crystal over a wide temperature range (300--2000 K) by combining first-principles-based self-consistent phonon theory unified including population coherence contributions. By considering from bubble loop diagrams, contributions both three-phonon (3ph) four-phonon (4ph) interaction processes to scattering rates energy shifts were clarified....

SnSe single crystals have been demonstrated to possess excellent thermoelectric properties. In this work, we demonstrate a grain size control method in growing nanocrystalline thin films through glancing angle pulsed-laser deposition approach. Structural characterization reveals that the film deposited at normal has preferred orientation along axis, while by contrast, an 80° develops nanopillar structure with growth direction towards incident atomic flux. The greatly reduces of due shadowing...
Triplet-state dissolved organic matter (3DOM*) plays a crucial role in environmental aquatic photochemistry, with 2,4,6-trimethylphenol (TMP) frequently used as chemical probe or quencher due to its high reactivity 3DOM*. However, the influence of TMP-derived oxidation intermediates on target photochemical reactions has not been comprehensively examined. This study investigated TMP's effect photolysis sulfamethoxazole (SMX), common antibiotic found natural waters, presence different DOM...
Abstract In this work, a silver nanoparticle‐boron nitride nanoplate (Ag‐BN) hybrid filler was prepared using an effective microwave‐heating method in only 2 min and utilized as functional for polyvinylidene fluoride (PVDF)‐based composite. The successful deposition of Ag nanoparticles on BN nanoplates, forming the Ag‐BN filler, confirmed through series microstructural characterizations FTIR, WAXD, UV–Vis, SEM, TEM, EDS mapping. Furthermore, it found that incorporation into PVDF effectively...
Accurately describing the lattice dynamics and microscopic mechanism of thermal transport in materials with low-lying flat phonon modes remains an outstanding challenge due to intrinsic strong anharmonicity.

Recent research pointed out that the degree of inflammation in adventitia could correlate with severity atherosclerotic plaques. Intravascular photoacoustic endoscopy can provide information arterial morphology and plaque composition, even detecting inflammation. However, most reported work used a noncoaxial configuration for catheter design, which formed limited light-sound overlap area imaging so as to miss information. Here we developed novel 0.9 mm-diameter intravascular coaxial...
