Residual contaminants in dye-penetrant testing [PDF]

, 1981
Components of the dye-penetrant-testing process were characterized by microanalytical methods. Particulate material of a size range, which was small enough to plug the small leaks in thin-walled cans, was found. Testing of simulated leaks before and after dye-penetrant examination showed that the dye-penetrant testing had a high probability of plugging

Dye-sensitized solar cells with 13% efficiency achieved through the molecular engineering of porphyrin sensitizers [PDF]

, 2014
Dye-sensitized solar cells have gained widespread attention in recent years because of their low production costs, ease of fabrication and tunable optical properties, such as colour and transparency. Here, we report a molecularly engineered porphyrin dye,

THE PENETRATION OF DYES AS INFLUENCED BY HYDROGEN ION CONCENTRATION [PDF]

Journal of General Physiology, 1923
When cells of Nitella are placed in buffer solutions at pH 9, there is a very slow and gradual increase in the pH of the sap from pH 5.6 to 6.4 (when death of the cells takes place). If the living cells are placed in 0.002 per cent dye solutions of brilliant cresyl blue at different pH values (from pH 6.6 to pH 9), it is found that the rate of ...

A comparative study of microleakage between giomer and ormocer restoration in class I cavity of first permanent premolar teeth in vivo

Bangabandhu Sheikh Mujib Medical University Journal, 2017
This study was performed to compare the marginal microleakage of ormocer restorative material with that of giomer in vivo. Forty Class I cavities were prepared in non-carious permanent premolar teeth from 10 patients.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.
