Comparison of NIR powders to conventional fingerprint powders
Forensic Science International, 2021Fingerprint powders remain one of the most common detection techniques used at the crime scene. However, powder efficiency and contrast can be hindered when applied to highly patterned backgrounds. This problem can be overcome using powders that are luminescent in the near-infrared (NIR) region of the electromagnetic spectrum.

The factors affecting powder mixing are reviewed. Methods of analyzing a random mix are discussed (indices, the Poisson distribution, and analyses of variance [ANOVA]). The influence of particle size, shape, and density are described, along with scale of scrutiny and sampling. Segregation and agglomeration are major problems in powder mixing, and their

The factors involved when sampling powder mixes have been reviewed. The various methods are evaluated (manual, automatic, and sub-sampling) and the errors incurred are discussed. Certain rules have been applied to various samplers and their suitability for powder mixtures are described.

Powder metallurgy of nanometric aluminium powders
Powder Metallurgy, 2008AbstractThe powder metallurgy processing (the compaction and the sintering) of aluminium nanocrystalline powder (with particle size of 100 nm) fabricated using a condensation process, has been studied. The compaction data were analysed using the Konopicky-Shapiro approach.
