Pathogen-host reorganization during Chlamydia invasion revealed by cryo-electron tomography [PDF]

open access: yes, 2014
Invasion of host cells is a key early event during bacterial infection, but the underlying pathogen-host interactions are yet to be fully visualised in three-dimensional detail.

Structure of the cell envelope of Halobacterium halobium [PDF]

open access: yes, 1976
The structure of the isolated cell envelope of Halobacterium halobium is studied by X-ray diffraction, electron microscopy, and biochemical analysis. The envelope consists of the cell membrane and two layers of protein outside. The outer layer of protein

Fusion of secretory vesicles isolated from rat liver [PDF]

open access: yes, 1978
Secretory vesicles isolated from rat liver were found to fuse after exposure to Ca2+. Vescle fusion is characterized by the occurrence of twinned vesicles with a continuous cleavage plane between two vesicles in freeze-fracture electron microscopy.

Improved Cryofixation Applicable to Freeze Etching [PDF]

open access: yesProceedings of the National Academy of Sciences, 1971
Freeze etching of solute model systems (e.g., glycerol or ferritin solutions) demonstrates that cryofixation can introduce serious artifacts due to the segregation of the dissolved or dispersed material from the solvent. Since, in principle, this problem can be reduced by increasing the cooling rate, a new technique has been developed which combines ...

A Cryosectioning Technique for the Observation of Intracellular Structures and Immunocytochemistry of Tissues in Atomic Force Microscopy (AFM)

open access: yesScientific Reports, 2017
The use of cryosectioning facilitates the morphological analysis and immunocytochemistry of cells in tissues in atomic force microscopy (AFM). The cantilever can access all parts of a tissue sample in cryosections after the embedding medium (sucrose) has

Loss and reappearance of gap junctions in regenerating liver [PDF]

open access: yes, 1978
Changes in intercellular junctional morphology associated with rat liver regeneration were examined in a freeze-fracture study. After a two-thirds partial hepatectomy, both gap junctions and zonulae occludentes were drastically altered.

Nanoscale tunnel field effect transistor based on a complex oxide lateral heterostructure [PDF]

open access: yes, 2019
We demonstrate a tunnel field effect transistor based on a lateral heterostructure patterned from an $\mathrm{LaAlO_3/SrTiO_3}$ electron gas. Charge is injected by tunneling from the $\mathrm{LaAlO_3}$/$\mathrm{SrTiO_3}$ contacts and the current through ...

Advances in Ductile Iron Research: new metallurgical understanding and its technological significance [PDF]

open access: yes, 2005
The present work gives an updated view about important metallurgical concepts, concerning the influence that solidification structure, microsegregation, piece size and austenite characteristics, exert on final microstructure, properties and processing ...
