When an earthworm reaches reproductive age, its clitellum, also referred to as the genital collar, observably enlarges and becomes more glandular. Genital features in Megascolecidae, including male and female pores, papi...

Reducing radiation damage is becoming a crucial factor in the development of future electron microscopes. The concept of interaction-free imaging utilizing a Mach–Zehnder interferometer has been proposed originally in....

The Volta phase plate (VPP) can enhance low-frequency phase contrast in cryo-electron microscopy (cryo-EM) and cryo-electron tomography (cryo-ET), but its impact on tomogram alignment has not been systematically assessed...

Abstract High-harmonic generation and ultrafast electron coherent control are central goals in modern strong-field physics. However, the problem of producing and manipulating electron-matter-wave pulses at zeptosecond ti...

Stimulated Raman scattering (SRS) microscopy is a fast Raman imaging technique that combines the molecular specificity of vibrational spectroscopy with the high spatial resolution and speed of laser-scanning microscopy. ...

Understanding solute segregation at twin boundaries (TBs) is essential for tailoring the microstructure and properties of magnesium alloys. Using in situ scanning transmission electron microscopy, we directly observe the...

Abstract The dissemination route of brain metastases dictates their spatiotemporal distribution, but whether it alters the ultrastructural state of the blood-tumor barrier remains unresolved. Here, we compared a modified...

As part of a survey of the remarkable diversity of Facetotecta (“y-larvae”) at an Okinawan (Japan) hotspot locality, a very small and relatively abundant species of this group, Hansenocaris lenticula sp. nov. (former...

A pressing issue in materials science is the controlled application of ceramic composite materials at high temperatures in modern technologies, particularly in nuclear physics, atomic energy, aerospace, and rocket engine...

The microstructure evolution and performance characteristics of the heat-affected zone (HAZ) in laser welding of 10Ni5CrMoV steel are investigated. By designing novel thermal simulation specimens and utilizing a thermal ...

Abstract In response to concerns of environmental pollution caused by hazardous dyes, remediating these dyes is a challenge. Herein, we developed a genetic algorithm-artificial neural network (GA-ANN) based optimization ...

Fowl adenovirus serotype 11 (FAdV-11) causes inclusion body hepatitis, posing a persistent threat to poultry health. However, the genetic determinants governing its pathogenicity remain unclear. Comparative analysis of p...

Objective: The objective of this study was to synthesise a novel silver nanocomposite incorporating quorum-quenching enzyme N-acyl-homoserine lactone-lactonase Est816 (Ag-Est816) to inhibit periodontal biofilm formation....

To investigate the effect of boron nitride (BN) content on the explosion performance of on-site mixed emulsion explosives, the microstructure of BN-containing on-site mixed emulsion explosives were characterized by trans...

Abstract A fiber laser was used to perform multiple laser cladding passes on AISI 1045 steel to fabricate SiC particle-reinforced Ni60A alloy coatings. The microstructure and phase composition of the cladding layers were...

ObjectiveDry eye disease (DED) is a common ocular surface disorder characterized by tear film instability and trigeminal nerve-mediated corneal hyperesthesia. Periocular acupuncture has been demonstrated to relieve DED s...

الملخص: أهداف البحث: هدفت هذه الدراسة إلى تقييم الخصائص السطحية للغرسات المصنَّعة من بولي ميثيل ميثاكريلات وهيدروكسي أب...

Polyisoprene (PI), whether naturally or synthetically produced, is used in rubber compounds for many applications, such as tires, belts, and shoes. The effect of Nano ternary silica (NTS) addition on the thermal and mech...

Laser powder bed fusion (L-PBF) technology has undergone rapid development in recent years. Owing to its advantages of high speed, efficiency, intelligence, and full flexibility, it exhibits significant potential for rea...

Abstract Growing environmental problems and the threat of an energy crisis have created an urgent need for affordable and efficient photocatalysts that can work under UV light to remove pollutants. In this work, Zinc fer...

Abstract A novel Schiff base (L) was synthesized via the condensation of folic acid with salicylaldehyde, and its copper (II) complex (Cu–L complex) was subsequently prepared, exhibiting notable biological activity. Co...

Tuberculosis (TB) continues to be one of the foremost public health issues in the world, and remains the second most salient communicable cause of death after COVID-19. In 2022, TB accounted for 10.6 million new infectio...
