Charge transport manipulation of lead‐free perovskite A3Sb2X9 single crystal for stable and sensitive x‐ray detection

InfoMat, Volume 8, Issue 8, August 2026.
Low‐dimensional perovskites can effectively improve device stability and reduce leakage current, showing broad application prospects in the field of high‐energy radiation detection. In this work, high‐quality and large‐size lead‐free A3Sb2X9 single crystals were grown via a solution method, and the modulation mechanism of charge transport was ...

Strain Imaging of GaAs by Stimulated Raman Scattering Microscopy

Journal of Raman Spectroscopy, Volume 57, Issue 8, Page 1387-1391, August 2026.
Telecom‐wavelength stimulated Raman scattering (SRS) microscopy is developed for high‐throughput, nondestructive characterization of gallium arsenide (GaAs). By overcoming optical absorption limits of conventional Raman systems, this technique enables precise visualization of LO phonon frequency variations (< 0.2‐cm −1 precision).

Managing Spectral Intensity Variations With In‐Line Fiber‐Optic High‐Volume Noncontact Raman Probes: A Strategy Exploration

Journal of Raman Spectroscopy, Volume 57, Issue 8, Page 1325-1338, August 2026.
Robust quantification in noncontact Raman sensing requires dedicated correction of working distance dependent background effects, while laser power variations are readily stabilized using internal reference signals. Chemically relevant Raman intensity can be preserved for bulk composition measurements, under variable laser power and working distance ...

Soil‐Applied Silicon Does Not Affect the Performance of Aphis craccivora on Cowpea Genotypes

Entomological Research, Volume 56, Issue 8, August 2026.
ABSTRACT Cowpea (Vigna unguiculata) is an important crop in tropical regions, where infestations of the black aphid, Aphis craccivora Koch (Hemiptera: Aphididae), can significantly reduce productivity. Silicon (Si) fertilization has been proposed as a strategy to enhance plant resistance to herbivores, although its effectiveness varies among plant ...

Diversity of Mites Associated With Stingless Bees (Hymenoptera: Meliponini) in Forest Fragments in Brazil: Empirical Validation of an Efficient and Low‐Cost Sampling Method

Austral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT Despite the importance of understanding mite–bee interactions, standardized and noninvasive methods for sampling mite communities in stingless bee hives remain limited. This study aimed to evaluate a novel, low‐cost sampling technique using a custom‐built suction device, the Portable Mite Aspirator (PMA), for collecting mites from hives of ...

Nondestructive Testing of Welded Composite Metal Foams

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.

Rapid THz nondestructive inspection of medicine capsules

Optics Express
In this study, we developed a screening tool for the rapid identification of defects in two-piece medicine capsules. We used THz time-of-flight (ToF) imaging by incorporating motorized rubber rollers, which allows rapid inspection of the capsules along their cylindrical surface.
