Accurate estimation of signal-to-noise ratio (SNR) in Scanning Electron Microscopy (SEM) is crucial because it evaluates the image quality. SEM images faced a challenge whereby Gaussian noise commonly appears in the imag...

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...

Slot bracket base is one important element to enable sliding movement of the archwire. Bracket reconditioning by means of burning changes the surface roughness of slot bracket base. The heat above 450 °C shows microstru...

The luminescence and inner structure of GaAs-AlGaAs quantum well tube (QWT) nanowires were studied using low-temperature cathodoluminescence (CL) spectroscopic imaging, in combination with scanning transmission electron ...

Abstract Background Human patients with Ehlers‐Danlos syndrome (EDS) are categorized into subtypes based on causative genetic variants and phenotypes. The classical form of EDS, primarily caused by variants in COL5A1 o...

Component interaction in the Tl2Te – SiTe2 and Tl2SiTe3 – Cd(Hg)Te systems was investigated by X-ray diffraction (XRD), differential thermal analysis (DTA), and scanning electron microscopy with energy dispersive spe...

This article presents a simple method towards the preparation of functionalized silver nanoparticles in a continuous medium. Silver nanoparticles were obtained through AgNO3 chemical reduction in ethanol and triethylenet...

The process which involves ionic exchange was applied with the use of a Mexican zeolitic mineral (Taxco-Guerrero) to remove Zn, Cd, and Ni from an aqueous solutions. Mineral zeolitic samples in their sodium form were put...

We studied the near-field properties of localized surface plasmon resonances in finite linear gold nanochains using photoemission electron microscopy (PEEM). The localization of the electromagnetic field in the near-fiel...

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...

CdSe is II-VI semiconductor with compact hexagonal structure. It has a band gap of 1.82 eV and a high stopping power for nuclear radiation. Single crystalline CdSe ingots were grown by Physical Vapor Transport (PVT) empl...

Abstract Physaloptera Rudolphi, 1819 is a genus of nematodes that includes approximately 100 species parasitic in vertebrates around the world. From these, approximately 30 occur in the Neotropical region, with nine repo...

We have designed, fabricated and tested a lens with a chromatic aberration coefficient (Cc) of 1.0 mm, a 4.0 mm pole-gap and 2.0 mm bore that is wide enough to accommodate an anti-contamination system and an object...

On-chip photonic networks require adequately spatially ordered matter-photon interconversion qubit sources with emission figures-of-merit exceeding the requirements that would enable the desired functional response of th...

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...

This study reports the changes in fatty acids, taste, and microstructure of cooked southern king crab meat (Lithodes santolla) during storage at 0°C for 10 days and at −20°C for 90 days. At the end of both storage ti...

Cerium-based materials were intensively studied in last years because of their high oxygen storage capacity (OSC) associated to the reversible Ce4+ Ce3+ process and their properties closely related to the defect chemistr...

Spectroscopic photoemission microscopy is used to detect and quantify a ponderomotive shift in the energy of electrons that are emitted from a surface plasmon polariton focus. The focus is formed on an atomically flat Au...

Spintronics based on ferromagnetic metals and organic semiconductors has attracted great interest in recent years. Molecular-based spintronic devices, such as magnetic tunnel junctions, have been demonstrated with perfor...

Calcareous sand is a special kind of geotechnical sand which consists of much carbonate. Based on the remains of the original marine organisms, the calcareous sand grains have irregular shapes and contain inner pores. Th...

Several metal-organic framework (MOF) materials have been recently employed in optoelectronic devices due to the unique properties of the MOF materials that result in enhanced performance and stability. In this work, the...

High-power density output in enzymatic fuel cells is a key feature to reduce the size of self-powered implantable medical devices. Electron transfer mediated through redox polyelectrolytes allows the transport of electro...

Nonlinear optics, when combined with microscopy, is known to provide advantages including novel contrast, deep tissue observation, and minimal invasiveness. In addition, special nonlinearities, such as switch on/off and ...

Photoacoustic imaging (PAI) is a noninvasive biomedical imaging technology capable of multiscale imaging of biological samples from organs down to cells. Multiscale PAI requires different ultrasound transducers that are ...
