29+ min ago   (271+ words) This work presents a conditional deep convolutional generative adversarial network (CDCGAN) for the inverse design of high-absorptance periodic metasurfaces (MSs) with different geometries. The conditioning mechanism encodes geometric and spectral parameters. A key innovation is the inclusion of unit cells…...

2+ day, 18+ hour ago   (389+ words) This study develops an analytical–evolutionary framework for optimizing the dynamic efficiency of bidirectional porous functionally graded beams. Touratier’s higher-order shear deformation theory is coupled with a real-coded genetic algorithm. The material-gradation indices in the thickness and width directions, the…...

3+ day, 21+ hour ago   (14+ words) Computational chemistry has become an essential bridge between microscopic theory and measurable chemical behaviour [...]...

4+ day, 23+ hour ago   (485+ words) Daidzein is a natural flavonoid with low aqueous solubility and bioavailability. The low-frequency terahertz spectroscopic characteristics and corresponding vibrational origins of the 1:1 daidzein–piperazine (DAI–PIP) crystalline system remain insufficiently explored. In this study, a DAI–PIP crystalline solid form was…...

1+ week, 1+ day ago   (509+ words) Freeze-dried sweet potato powders derived from three distinct genotypes—white (Koretta), orange (Ro-Ch-G), and purple (Ro-Ch-M)—were comprehensively characterized with respect to their proximate composition, phenolic profile, antioxidant activity, color attributes, and mineral composition. The purple sweet potato powder showed…...

1+ week, 2+ day ago   (317+ words) A comprehensive Quasi-Classical Trajectory (QCT) investigation is reported for the hydrogen-abstraction reaction, OH (ν = 0, j = 2) + D2 (ν = 0, j = 2) → HOD* + D, aimed at clarifying the mechanisms of energy and angular-momentum disposal in the excited product molecule, HOD*. Calculations were performed on the…...

1+ week, 3+ day ago   (249+ words) AgInSe2 (AISe) nanocrystals, with their outstanding optoelectronic properties and environmentally friendly, Cd/Pb-free composition, show strong potential for applications in near-infrared luminescence and photovoltaic devices. Herein, metastable orthorhombic AISe nanocrystals were synthesized using a simplified, efficient, and environmentally friendly strategy. The…...

1+ week, 4+ day ago   (514+ words) Accurate estimation of uniaxial compressive strength (UCS) is essential in geotechnical engineering, but conventional UCS testing is destructive and time-consuming. This study investigates the effects of mild acid exposure and freeze–thaw (F–T) cycling on the relationships between P-wave velocity…...
