Microstructural, mechanical, and electrochemical analysis of carbon doped AISI carbon steels

open access: yesApplied Microscopy, 2022
The effect of carbon doping contents on the microstructure, hardness, and corrosion properties of heat-treated AISI steel grades of plain carbon steel was investigated in this study. Various microstructures including coarse ferrite-pearlite, fine ferrite-

Review on the structural understanding of the 10S myosin II in the era of Cryo-electron microscopy

open access: yesApplied Microscopy, 2022
The compact smooth muscle 10S myosin II is a type of a monomer with folded tail and the heads bending back to interact with each other. This inactivated form is associated with regulatory and enzymatic activities affecting myosin processivity with actin ...

Capture silk scaffold production in the cribellar web spider

open access: yesApplied Microscopy, 2021
Spider capture silk is a natural scaffolding material that outperforms most synthetic materials in terms of its combination of strength and elasticity. Among the various kinds of silk threads, cribellar thread is the most primitive prey-capturing type of

Changes of lysosome by L-serine in rotenone-treated hippocampal neurons

open access: yesApplied Microscopy, 2023
Oxidative stress destroys cellular organelles and damages DNA, eventually leading to degenerative brain disorders. Persistent mitochondrial damage by oxidative stress eventually causes cells to inhibit the function of lysosomes.

THE USE OF LEAD CITRATE AT HIGH pH AS AN ELECTRON-OPAQUE STAIN IN ELECTRON MICROSCOPY

open access: yesJournal of Cell Biology, 1963
Aqueous solutions of lead salts (1, 2) and saturated solutions of lead hydroxide (1) have been used as stains to enhance the electron-scattering properties of components of biological materials examined in the electron microscope.

Scanning Quantum Dot Microscopy [PDF]

open access: yes, 2015
Interactions between atomic and molecular objects are to a large extent defined by the nanoscale electrostatic potentials which these objects produce. We introduce a scanning probe technique that enables three-dimensional imaging of local electrostatic ...

Light and electron microscopic morphology of the fertilized egg and fertilized egg envelope of Poropanchax normani, Poeciliidae, Teleostei

open access: yesApplied Microscopy, 2022
We examined the morphology of the fertilized egg and the fine structure of fertilized egg envelopes of Poropanchax normani belonging to the family Poeciliidae, also known as Norman’s lampeye using light and electron microscopes.
