TL;DR: In this article, a review of semiconductor gas sensor literature pertaining to the use of temperature modulation techniques is presented, along with transient and cyclic modulation techniques for improving sensitivity and selectivity of sensors.

TL;DR: The application of quantitative elemental bio-imaging for the determination of the distribution Cu, Mn, Fe and Zn in Parkinsonism mouse model brains shows high concentrations of Fe within the substantia nigra of the lesioned animals.

TL;DR: In this paper, several varieties of blue ballpoint pen inks were analyzed by high performance liquid chromatography (HPLC) and infrared spectroscopy (IR) and the chromatographic data extracted at four wavelengths (254, 279, 370 and 400 nm) was analyzed individually and at a combination of these wavelengths by the soft independent modeling of class analogies (SIMCA) technique using principal components analysis (PCA) to estimate the separation between the pen samples.

TL;DR: A new technique, Fourier transform infrared (FTIR) chemical imaging, has been demonstrated for the enhancement of latent fingermarks on a number of surfaces, including the Australian polymer banknote.

TL;DR: In this paper, the spectral angle mapper (SAM) and correlation algorithms were tested for their efficacy in finding targeted substances deposited within fingerprints, and the SAM was used to successfully locate explosive components in fingerprints on silicon windows.
