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
Barry G. H. Janssen, Mohamadreza Najiminaini, Yan Min Zhang, Parsa Omidi, Jeffrey J. L. Carson
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... hiện toàn bộ
Depth-dependent EBIC microscopy of radial-junction Si micropillar arrays
Springer Science and Business Media LLC - Tập 50 - Trang 1-9 - 2020
Kaden M. Powell, Heayoung P. Yoon
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... hiện toàn bộ
Microstructure analysis of 8 μm electrolytic Cu foil in plane view using EBSD and TEM
Springer Science and Business Media LLC - Tập 52 - Trang 1-6 - 2022
Myeongjin Kim, Hyun Soon Park
With the lightening of the mobile devices, thinning of electrolytic copper foil, which is mainly used as an anode collection of lithium secondary batteries, is needed. As the copper foil becomes ultrathin, mechanical properties such as deterioration of elongation rate and tear phenomenon are occurring, which is closely related to microstructure. However, there is a problem that it is not easy to p... hiện toàn bộ
A simple and rapid preparation of smooth muscle myosin 2 for the electron microscopic analysis
Springer Science and Business Media LLC -
Anahita Vispi Bharda, Hyun Suk Jung
AbstractThere has been an increase in the demand for purified protein as a result of recent developments in the structural biology of myosin 2. Although promising, current practices in myosin purification are usually time-consuming and cumbersome. The reported increased actin to myosin ratio in smooth muscles adds to the complexity of the purification process. Present study outlines a streamlined ... hiện toàn bộ
Hair microscopy: an easy adjunct to diagnosis of systemic diseases in children
Springer Science and Business Media LLC - Tập 51 - Trang 1-12 - 2021
Dharmagat Bhattarai, Aaqib Zaffar Banday, Rohit Sadanand, Kanika Arora, Gurjit Kaur, Satish Sharma, Amit Rawat
Hair, having distinct stages of growth, is a dynamic component of the integumentary system. Nonetheless, derangement in its structure and growth pattern often provides vital clues for the diagnosis of systemic diseases. Assessment of the hair structure by various microscopy techniques is, hence, a valuable tool for the diagnosis of several systemic and cutaneous disorders. Systemic illnesses like ... hiện toàn bộ
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
Hyunung Yu
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... hiện toàn bộ

Formation of two-dimensional MoS2 and one-dimensional MoO2 nanowire hybrids
Springer Science and Business Media LLC - Tập 49 - Trang 1-2 - 2019
Aram Yoon, Zonghoon Lee
Oxidation of two-dimensional (2D) transition metal dichalcogenides have received great interests because it significantly influences their electrical, optical, and catalytic properties. Monoclinic MoO2 nanowires grow along the zigzag direction of 2D MoS2 via thermal annealing at a high temperature with a low oxygen partial pressure. The hybrids of semiconducting 2D MoS2 and metallic 1D MoO2 nanowi... hiện toàn bộ
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
Ziv Frankenstein, Naohiro Uraoka, Umut Aypar, Ruth Aryeequaye, Mamta Rao, Meera Hameed, Yanming Zhang, Yukako Yagi
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
Anatomy, ultrastructure and histology of the olfactory organ of the largemouth bass Micropterus salmoides, Centrarchidae
Springer Science and Business Media LLC - Tập 49 Số 1 - 2019
Hyun Tae Kim, Seung Woon Yun, Jong Young Park
AbstractThe detailed anatomy, ultrastructure and histology of the olfactory organ ofMicropterus salmoideswere investigated by a stereo microscope, a light microscope, and a scanning electron microscope. Its external structure shows a tube-like anterior nostril to stick out and a posterior nostril flat to the skin surface. Meanwhile, its internal structure, the olfactory chamber, contains a fan-sha... hiện toàn bộ
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
Hong-Kyu Kim, Sung-Hoon Kim, Jae-Pyoung Ahn
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... hiện toàn bộ
