Infrared Macrothermoscopy Patterns—A New Category of Dermoscopy
(1) Background: The authors developed a new non-invasive dermatological infrared macroimaging analysis technique (MacroIR) that evaluates microvascular, inflammatory, and metabolic changes that may be dermoscopy complimentary, by analyzing different skin

Characterization and discrimination of soils by their reflected electromagnetic energy [PDF]
The objective of this work was to verify if reflected energy of soils can characterize and discriminate them. A spectroradiometer (Spectral reflectance between: 400-2,500 nm) was utilized in laboratory. The soils evaluated are located in Bauru region, SP,

Synthesis and virtual screening of bis-(4-(tert-butyl)-N-(methylcarbamothioyl) benzamide)-Iron (III) complex as an anticancer candidate [PDF]
Thiourea derivatives were much used in drug discovery and drug-making, such as for an anticancer. The formation of drug complexes can increase lipophilicity through chelation formation, and the drug action is significantly upward due to the effective ...

Detection of Solvents by Infrared Spectrophotometry [PDF]
Abstract The solvent used in the recrystallization of a solid may be determined by use of the IR spectrum and gas cell. Recrystallized powders retain a minute amount of solvent which is not detectable in a KBr disk of the powder, but is detectable when a gas cell is vised.
