Case report: identification of elemental mercury - Kenny K, Sandercock M, Webster J.

Two cases where elemental mercury was intentionally added to the victim's food are briefly described. Elemental mercury may be identified by using a combination of physical properties (appearance and specific gravity) and elemental analysis (scanning elect...

Publication date: 15 April 2020Source: Scripta Materialia, Volume 180Author(s): Jinxian Huang, Lei Feng, Cong Li, Chunfa Huang, Jianguo Li, Bernd FriedrichAbstractA poisoning effect of scandium (Sc) with respect to Al-5Ti-1B (in wt.%) grain refiner was investigated for the first time. Grain refinement effect of Al-5Ti-1B was found to fade in Al alloys with content of trace Sc. The modification of TiB2 particle by inward diffusion of Sc was characterized by high-resolution transmission electron microscope (HRTEM). Through Geometric Phase Analysis (GPA) analysis, a notable increase of stress concentration at (0001) plane of ...

In this study, we report the observation that the diffusion-limited current (DLC) of hydrogen evolution reaction (HER) on Pt surface is largely surface poison-resisting to carbon monoxide and thiol, two well-known Pt surface poisons. Building upon this observation, we proposed and tested a technique for amperometrically measuring localized proton concentration with a sub-μm spatial resolution through the utilization of a linear pH dependence of HER DLC on a Pt ultramicroelectrode, hereby referred to as Scanning Amperometric Proton Microscopy (SAPM). By bringing the Pt ultramicroelectrode close to a proton generating/con...

In this study, for the first time, we reported a fast and facile three-step in situ strategy for direct controllable growth of the Co3(BTC)2 MOFs thin films on the GCE, through the rapid conversion of the electrodeposited Co(OH)2 nano-flakes on rGO/GCE, to crystalline rectangular bar-shape structures of MOFs. X-ray diffraction spectroscopy, Fourier transform infrared spectroscopy, field emission scanning electron microscopy, energy dispersive X-ray spectroscopy and elemental mapping analysis used to the structural and morphological characterization of the well-synthesized MOFs. The as-prepared Co3(BTC)2 MOFs were used to c...

Publication date: Available online 5 January 2020Source: Chinese Chemical LettersAuthor(s): Xiaoyu Zhao, Huachao Zhao, Jiefang Sun, Gang Li, Rui LiuAbstractAnodic electrocatalyst plays the core role in direct alcohol fuel cells (DAFCs), while traditional Pt-catalysts suffer from limited catalytic activity, high over potential and severe CO poisoning. Herein, by selectively depositing Rh atoms on the defective-sites of Pt nanowires (NWs), we developed a new Pt@Rh NW electrocatalyst that exhibited enhanced electrocatalytic performance for both methanol oxidation (MOR) and ethanol oxidation (EOR). Both cyclic voltammetry (CV)...

Conclusions: DUIMS indicates higher mortality, and DUIMS' profiles in causes of death differ from the general population. Elevated risk for, for instance, suicidal, accidental and violent death among those using multiple substances highlights the need to also pay attention to causes of death other than poisoning/overdose.
