Extensible LED-Induced Integrated Fluorescence Detection Module for Quantitative Analysis of Lucigenin Concentration

open access: yesPhotonics, 2023
We developed an extensible LED-induced fluorescence detection module with a highly integrated and ultra-compact structure. A target-oriented design methodology was used to demonstrate the module’s optimal design.

Identification of programmed cell death in situ via specific labeling of nuclear DNA fragmentation

open access: yesJournal of Cell Biology, 1992
Programmed cell death (PCD) plays a key role in developmental biology and in maintenance of the steady state in continuously renewing tissues. Currently, its existence is inferred mainly from gel electrophoresis of a pooled DNA extract as PCD was shown ...

Phylogenetic identification and in situ detection of individual microbial cells without cultivation.

open access: yesMicrobiological reviews, 1995
The frequent discrepancy between direct microscopic counts and numbers of culturable bacteria from environmental samples is just one of several indications that we currently know only a minor part of the diversity of microorganisms in nature.

Evolution of mining‐induced stress in fully mechanized top‐coal caving under high horizontal stress

open access: yesEnergy Science & Engineering, 2020
In fully mechanized top‐coal caving (FMTC), the effects of coal caving are closely related to the degree of damage to the top‐coal which is determined by the stress state therein.

A comparison of in- and ex situ generated shear bands in metallic glass by transmission electron microscopy [PDF]

open access: yesMetals 12 2022, 2021
Shear bands originating from in situ tensile tests of Al$_{88}$Y$_{7}$Fe$_{5}$ melt-spun ribbons conducted in a transmission electron microscope are compared with ones which had formed ex situ during cold rolling. During in situ straining, the observations of a spearhead-like shear front, a meniscus-like foil thickness reduction and no apparent shear ...
