Spatial distribution of uranium isotopes in solid nuclear materials using laser ablation multi-collector ICP-MS 10.1016/j.microc.2018.03.038 2018-03-30 Employing laser ablation multi-collector ICP-MS (LA-MC-ICP-MS), its potential for evaluating the homogeneity of solid uranium (U) bearing materials was investigated. To this end, the n(235U)/n(238U) ratio of two low-enriched U certified reference materials (C...
Spectroscopic methods for the identification and photostability study of red synthetic organic pigments in alkyd and acrylic paints 10.1016/j.microc.2018.02.029 2018-03-29 The photostability of red synthetic organic pigments of three different chemical classes such as naphthol AS (PR112), diketopyrrolopyrrole (PR254 and 255), and quinacridone (PR122 and red shaded PV19) is investigated in the present work. In particular, the st...

Research on electronic nose system based on continuous wide spectral gas sensing 10.1016/j.microc.2018.03.030 2018-03-23 Light absorption gas sensing technology has characteristics of massive parallelism, cross-sensitivity and extensive responsiveness which make it suitable for the sensing task of an electronic nose (e-nose). Therefore, an innovational e-nose system based on co...
Reconstruction of chemical fingerprints from an individual's time-delayed, overlapped fingerprints via laser-induced breakdown spectrometry (LIBS) and Raman spectroscopy 10.1016/j.microc.2018.03.027 2018-03-21 Laser-induced breakdown spectroscopy (LIBS) is a method for atomic emission analysis that can be used to analyze the chemical composition of samples in the forensic investigations. The combined effort of extracting, analyzing, and restoring latent fingerprint...
Development of a nanostructured electrochemical immunosensor applied to the early detection of invasive aspergillosis 10.1016/j.microc.2018.03.025 2018-03-16 The use of a biological marker as an adjunct for screening for invasive aspergillosis (IA) in high-risk patients is attractive, because it is noninvasive and may detect evidence of IA prior to the appearance of clinical signs and symptoms. Galactomannan (GMN)...
Continuous monitoring of pH level in flow aqueous system by using liquid crystal-based sensor device 10.1016/j.microc.2018.03.020 2018-03-13 In this work, we report a liquid crystal (LC)-based sensor to determine pH level of aqueous solutions. This sensor was fabricated by filling the LCs doped with a pH-sensitive molecule into a cupper grid on a glass substrate. Theoretically, the dopants are neu...
Sensitive colorimetric detection of Cu2+ by simultaneous reaction and electrokinetic stacking on a paper-based analytical device 10.1016/j.microc.2018.03.021 2018-03-12 Paper-based analytical device (PAD) with image-based colorimetric detection is advantageous in low-cost, fast, simple and suitable for on-site rapid analysis. However, the detection capability is normally limited. In this paper, a new method was proposed that...
Switchable solvent based liquid phase microextraction of trace lead and cadmium from environmental and biological samples prior to graphite furnace atomic absorption spectrometry detection 10.1016/j.microc.2018.03.017 2018-03-10 A switchable hydrophilicity solvent (SHS) based liquid phase microextraction (LPME) method was proposed for the preconcentration of trace Pb (II) and Cd (II) followed by graphite furnace atomic absorption spectrometry (GFAAS) detection. The SHS of protonated ...
A study of non-bounded/bounded water and water mobility in different agar gels 10.1016/j.microc.2018.03.016 2018-03-09 Agar is an interesting and versatile biopolymer capable of forming hydrogels useful in different applications. In particular, in the field of Cultural Heritage agar gels are often used as tools for cleaning the surfaces of artifacts. Agar gels are thermorever...
