Summary: A rapid analytical procedure for the separation and pre-concentration of ultra trace level thallium from plant samples using high resolution continuum source electrothermal atomic absorption spectrometry has been described. The method involves the extraction of ionic thallium spices from the nitric acid digests of plant leaves using Triton X-100 micelles, HCl, and NaCl. The procedure has been optimized and the accuracy of the method has been verified by analyzing certified reference materials. The method has also been successfully applied to real plant samples collected near thermal power plants and industrial areas.

Summary: Tl isotopic compositions were used for the first time to explore the transfer and pathway of Tl in paddy soil system. The results showed considerable variations in Tl isotopes, which were likely caused by interconversion between Tl(I) and Tl(III) under different redox conditions. Industrial waste was found to be the predominant source of Tl contamination in the studied soil. These findings suggest that Tl isotopes can be used as an efficient tracer to fingerprint Tl pathway in complicated scenarios, with significant prospects in diverse environmental applications.

Summary: This study systematically investigated the impact of wood-derived biochar (WB) and corn straw-derived biochar (CB) colloids on Tl(I) transport in water-saturated porous media under different pH and ionic strengths. The results showed that WB colloids improved Tl(I) transport under all conditions, while CB colloids only promoted Tl(I) mobility at low ionic strength. The two-site nonequilibrium model and two-site kinetic attachment/detachment model effectively described the transport of Tl(I) and biochar colloids, respectively.

Summary: The Wacker process is commonly used for the conversion of monosubstituted alkenes to methyl ketones, but it is not applicable to the synthesis of ketones from 1,1-disubstituted alkenes. We have designed a PdII/PdIV catalytic cycle incorporating a 1,2-alkyl/PdIV dyotropic rearrangement as a key step, which successfully addresses this synthetic challenge.

Summary: This study evaluated the enrichment and migration mechanisms of thallium (Tl) and metal(loid)s in paddy soils surrounding an industrial park utilizing Tl-bearing minerals, showing Tl contamination and potential health risks. Results indicated that Tl(I) in the soils was controlled by adsorption, oxidation, and precipitation of Fe/Mn(hydr)oxides, potentially inhibiting Tl uptake by rice grains. The high health quotient (HQ) values suggested a potentially high Tl risk for inhabitants consuming the rice grains, highlighting the importance of controlling Tl discharge from industrial activities for food safety in rice paddy soils.

Summary: A remarkable distinction between boron and carbon hydrides lies in their different bonding patterns and chemical reactivity, resulting in diverse areas of application. Our knowledge of the hydride chemistry for elements in Group 13, especially thallium, is limited. In this work, we performed a conformational analysis of Tl2Hx and Tl3Hy (x=0-6, y=0-5) series and investigated the bonding pattern, stability, and electron detachment. All found global minimum structures are classified as non-classical structures featuring at least one multi-center bond.

Summary: The study found that secondary minerals could effectively remove toxic elements such as arsenic and thallium. In environments polluted by mining, these elements were abundant and a large percentage of total arsenic and thallium could be mobilized easily into the environment. Furthermore, new thallium arsenate phases were identified, highlighting the need for further research on thallium speciation in extremely arsenic- and thallium-rich environments.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.
