Multispectral intravital microscopy for simultaneous bright-field and fluorescence imaging of the microvasculature
Springer Science and Business Media LLC - Tập 51 - Trang 1-12 - 2021
Intravital video microscopy permits the observation of microcirculatory blood flow. This often requires fluorescent probes to visualize structures and dynamic processes that cannot be observed with conventional bright-field microscopy. Conventional light microscopes do not allow for simultaneous bright-field and fluorescent imaging. Moreover, in conventional microscopes, only one type of fluoresce......
Depth-dependent EBIC microscopy of radial-junction Si micropillar arrays
Springer Science and Business Media LLC - Tập 50 - Trang 1-9 - 2020
Recent advances in fabrication have enabled radial-junction architectures for cost-effective and high-performance optoelectronic devices. Unlike a planar PN junction, a radial-junction geometry maximizes the optical interaction in the three-dimensional (3D) structures, while effectively extracting the generated carriers via the conformal PN junction. In this paper, we report characterizations of r......
Kỹ thuật hiển vi âm thanh quét trong đánh giá vật liệu Dịch bởi AI
Springer Science and Business Media LLC - Tập 50 - Trang 1-11 - 2020
Kỹ thuật hiển vi âm thanh quét (Scanning Acoustic Microscopy - SAM) hay Hình ảnh Âm thanh Micro (Acoustic Micro Imaging - AMI) là một phương pháp hiệu quả, không phá hủy, có khả năng phát hiện các khuyết tật ẩn trong các mẫu đàn hồi và sinh học cũng như các vật liệu cứng không trong suốt. Bằng cách theo dõi các đặc điểm bên trong của một mẫu trong tích hợp ba chiều, kỹ thuật này có thể phát hiện h......

Methods to evaluate the twin formation energy: comparative studies of the atomic simulations and in-situ TEM tensile tests
Springer Science and Business Media LLC - Tập 50 - Trang 1-9 - 2020
Deformation twinning, one of the major deformation modes in a crystalline material, has typically been analyzed using generalized planar fault energy (GPFE) curves. Despite the significance of these curves in understanding the twin nucleation and its effect on the mechanical properties of crystals, their experimental validity is lacking. In this comparative study based on the first-principles calc......
Therapeutic treatments for diabetes mellitus-induced liver injury by regulating oxidative stress and inflammation
Springer Science and Business Media LLC - Tập 53 - Trang 1-11 - 2023
Diabetes mellitus (DM) is a metabolic disease that affects all systems in the body, including the liver. Numerous studies have reported that chronic DM etiology and pathogenesis complications implicate oxidative stress, generating reactive oxygen species, such as superoxide anions and free radicals. In addition, pro-inflammatory reactions are also underlying functions closely related to oxidative ......
Fine structure of the cardiac muscle cells in the orb-web spider Nephila clavata
Springer Science and Business Media LLC - Tập 50 - Trang 1-8 - 2020
The fine structural characteristics of cardiac muscle cells and its myofibril organization in the orb web spider N. clavata were examined by transmission electron microscopy. Although myofibril striations are not remarkable as those of skeletal muscles, muscle fibers contain multiple myofibrils, abundant mitochondria, extensive sarcoplasmic reticulum and transverse tubules (T-tubules). Myofibrils ......
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......
Comparative study on the specimen thickness measurement using EELS and CBED methodsAbstract Two thickness measurement methods using an electron energy loss spectroscopy (EELS) and 10a convergent beam electron diffraction (CBED) were compared in an Fe-18Mn-0.7C alloy. The thin foil specimen was firstly tilted to satisfy 10a two-beam condition. Low loss spectra of EELS and CBED patterns were acquired in scanning transmission electron microscopy (STE... ...

Bergman glial cell morphology under the high voltage Electron microscope
Springer Science and Business Media LLC - Tập 49 - Trang 1-2 - 2019
The detailed morphology of Bergam glial cell was observed in single field of view during observation of Golgi stained mouse cerebellar cortex under the high voltage electron microscopy. The 3-dimensional organization of Bergman glial cell fully demonstrated with 8-degree stereo-paired images. The morphology of Bergman glial fiber and its appendages forming microdomains connected to other glial fib......
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 ......
