Quantitative analysis of retained austenite in Nb added Fe-based alloy
Springer Science and Business Media LLC - Tập 52 - Trang 1-10 - 2022
The use of Pipelines for long-distance transportation of crude oil, natural gas and similar applications is increasing and has pivotal importance in recent times. High specific strength plays a crucial role in improving transport efficiency through increased pressure and improved laying efficiency through reduced diameter and weight of line pipes. TRIP-based high-strength and high-ductility alloys...... hiện toàn bộ
Electron beam irradiation induced crystallization behavior of amorphous Ge2Sb2Te5 chalcogenide material
Springer Science and Business Media LLC - Tập 49 - Trang 1-2 - 2019
The crystallization of amorphous Ge2Sb2Te5 phase change material induced by electron beam irradiation was investigated by in-situ transmission electron microscopy (TEM). Amorphous matrix transformed into a partially crystalline state after being irradiated with a 200-keV electron beam for a long time. Real-time observation revealed that the crystallization of amorphous Ge2Sb2Te5 film occurs throug...... hiện toàn bộ
Ultrastructure of the fertilized egg envelope from Melanotaenia praecox, Melanotaeniidae, TeleosteiAbstract We examined the morphology of fertilized egg and ultrastructures of fertilized egg envelopes of dwarf rainbowfish (Melanotaenia praecox ) belong to Melanotaeniidae using light and electron microscopes. The fertilized eggs were spherical with adhesive filament, transparent, demersal, and had a narrow perivitelline space and small oi... ... hiện toàn bộ

Advanced atomic force microscopy-based techniques for nanoscale characterization of switching devices for emerging neuromorphic applications
Springer Science and Business Media LLC - Tập 51 - Trang 1-9 - 2021
Neuromorphic systems require integrated structures with high-density memory and selector devices to avoid interference and recognition errors between neighboring memory cells. To improve the performance of a selector device, it is important to understand the characteristics of the switching process. As changes by switching cycle occur at local nanoscale areas, a high-resolution analysis method is ...... hiện toàn bộ
TEM sample preparation of microsized LiMn2O4 powder using an ion slicer
Springer Science and Business Media LLC - Tập 51 - Trang 1-7 - 2021
The main purpose of this paper is the preparation of transmission electron microscopy (TEM) samples from the microsized powders of lithium-ion secondary batteries. To avoid artefacts during TEM sample preparation, the use of ion slicer milling for thinning and maintaining the intrinsic structure is described. Argon-ion milling techniques have been widely examined to make optimal specimens, thereby...... hiện toàn bộ
Chất liệu thăng hoa hỗ trợ việc chuẩn bị mẫu TEM cho các vật liệu nano tan trong dầu Dịch bởi AI Tóm tắt Việc chuẩn bị mẫu là rất quan trọng để xác định vật liệu nano bằng kính hiển vi điện tử truyền qua độ phân giải cao (HRTEM). Tuy nhiên, nhiều dung môi hữu cơ thông thường có thể hòa tan lớp hỗ trợ polymer hữu cơ cần thiết trong lưới TEM, điều này làm cho việc thu được mẫu chất lượng cao của các vật liệu nano tan trong dầu trở nên khó khăn. Trong nghiên cứu n... ... hiện toàn bộ

Methods of measuring presynaptic function with fluorescence probes
Springer Science and Business Media LLC - Tập 51 - Trang 1-7 - 2021
Synaptic vesicles, which are endogenous to neurotransmitters, are involved in exocytosis by active potentials and release neurotransmitters. Synaptic vesicles used in neurotransmitter release are reused via endocytosis to maintain a pool of synaptic vesicles. Synaptic vesicles show different types of exo- and endocytosis depending on animal species, type of nerve cell, and electrical activity. To ...... hiện toàn bộ
One-step synthesis of Pt/a-CoOx core/shell nanocomposites
Springer Science and Business Media LLC - Tập 49 - Trang 1-5 - 2019
Herein, we synthesize a core/shell Pt/a-CoOx nanocomposite via one-step synthesis using a strong reaction agent of borane t-butylamine(BBA) at 200 °C. Transmission electron microscopy study shows that the morphology of nanocomposites is controlled by the stirring time and perfect core/shell structure is formed with over 7 days stirring time.
Automated 3D scoring of fluorescence in situ hybridization (FISH) using a confocal whole slide imaging scanner
Springer Science and Business Media LLC - Tập 51 - Trang 1-12 - 2021
Fluorescence in situ hybridization (FISH) is a technique to visualize specific DNA/RNA sequences within the cell nuclei and provide the presence, location and structural integrity of genes on chromosomes. A confocal Whole Slide Imaging (WSI) scanner technology has superior depth resolution compared to wide-field fluorescence imaging. Confocal WSI has the ability to perform serial optical sections ...... hiện toàn bộ
Noise reduction of electron holography observations for a thin-foiled Nd-Fe-B specimen using the wavelet hidden Markov modelAbstract In this study, we investigate the effectiveness of noise reduction in electron holography, based on the wavelet hidden Markov model (WHMM), which allows the reasonable separation of weak signals from noise. Electron holography observations from a Nd2 Fe14 B thin foil showed that the noise reduction method suppressed ... ... hiện toàn bộ
