A mixed radial, angular, three-body distribution function as a tool for local structure characterization: Application to single-component structures.

J Chem Phys 2020 May;152(19):194502

Department of Materials Science and Engineering, Universität des Saarlandes, Saarbrücken, Germany.

A mixed radial, angular three-body distribution function g(r, θ) is introduced, which allows the local atomic order to be more easily characterized in a single graph than with conventional correlation functions. It can be defined to be proportional to the probability of finding an atom C at a distance r from atom B while making an angle θ with atoms A and B, under the condition that atom A is the nearest neighbor of B. As such, our correlation function contains, for example, the likelihood of angles formed between the nearest and the next-nearest-neighbor bonds. Read More

Environ Sci Pollut Res Int 2021 Feb 23;28(5):5455-5471. Epub 2020 Sep 23.

GEOtest, a.s., Šmahova 1244/112, 627 00, Brno, Czech Republic.

It is well known that road transport emits various trace elements into the environment, which are deposited in soils in the vicinity of roads, so-called roadside soils, and thus contributes to the deterioration of their chemical state. The aim of this work was to determine concentrations of some metals and metalloids (arsenic (As), cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), antimony (Sb), vanadium (V), and zinc (Zn)) in soils from crossroads with traffic signals, which are characterized by deceleration of vehicles and increased emissions of elements related mainly to brake and tyre wear. The results confirmed a moderate enrichment of soils with Cu, Pb, and Zn (enrichment factor (EF) values > 2) and significant enrichment for Sb (EF > 5), while the other elements showed no or minimal enrichment.

ACS Nano 2020 Oct 25;14(10):13938-13951. Epub 2020 Sep 25.

Key Laboratory for Liquid-Solid Structural Evolution and Processing of Materials, Ministry of Education, School of Materials Science and Engineering, Shandong University, Jinan 250061, P.R. China.

Taking into consideration the advantages of the highly theoretical capacity of antimony (Sb) and abundant surface redox reaction sites of Na pre-intercalated 3D porous TiCT (Na-TiCT) architectures, we elaborately designed the Sb/Na-TiCT hybrid with Sb nanoparticles homogeneously distributed in 3D porous Na-TiCT architectures through a facile electrostatic attraction and carbothermic reduction process. Na-TiCT architectures with more open structures and larger active specific surface area not only could certainly alleviate volume changes and hinder the aggregation of Sb nanoparticles in the cycling process to improve the structural stability but also significantly strengthen the electron-transfer kinetics and provide unblocked K diffusion channels to promote ionic/electronic transport rate. Furthermore, the ultrafine Sb nanoparticles could efficiently shorten K transport distance and expose more accessible active sites to improve capacity utilization. Read More

Expression and interactions of stereochemically active lone pairs and their relation to structural distortions and thermal conductivity.

IUCrJ 2020 May 31;7(Pt 3):480-489. Epub 2020 Mar 31.

Center for Materials Crystallography, Department of Chemistry and iNANO, Aarhus University, Langelandsgade 140, Aarhus 8000, Denmark.

In chemistry, stereochemically active lone pairs are typically described as an important non-bonding effect, and recent interest has centred on understanding the derived effect of lone pair expression on physical properties such as thermal conductivity. To manipulate such properties, it is essential to understand the conditions that lead to lone pair expression and provide a quantitative chemical description of their identity to allow comparison between systems. Here, density functional theory calculations are used first to establish the presence of stereochemically active lone pairs on antimony in the archetypical chalcogenide MnSbO. Read More

Relative Abundance of Thiolated Species of As, Mo, W, and Sb in Hot Springs of Yellowstone National Park and Iceland.

Environ Sci Technol 2020 04 23;54(7):4295-4304. Epub 2020 Mar 23.

Institute of Earth Sciences, University of Iceland, Sturlugata 7, 101 Reykjavík, Iceland.

Geothermal waters often are enriched in trace metal(loid)s, such as arsenic, antimony, molybdenum, and tungsten. The presence of sulfide can lead to the formation of thiolated anions; however, their contributions to total element concentrations typically remain unknown because nonsuitable sample stabilization and chromatographic separation methods convert them to oxyanions. Here, the concurrent widespread occurrence of thioarsenates, thiomolybdates, thiotungstates, and thioantimonates, in sulfide-rich hot springs from Yellowstone National Park and Iceland is shown.

Antimony selenide/graphene oxide composite for sensitive photoelectrochemical detection of DNA methyltransferase activity.

J Mater Chem B 2019 11 9;7(43):6789-6795. Epub 2019 Oct 9.

Medical School, School of Chemistry and Chemical Engineering, Southeast University, Nanjing 210009, China.

Antimony selenide (SbSe) as a p-type semiconductor material has recently attracted extensive attention for its excellent photoelectric properties in applications of thin film solar cells. However, applying SbSe as a photoelectrochemically (PEC) active material for constructing biosensors has never been reported. In this work, by using SbSe/graphene oxide (SbSe-GO) as both the PEC probe and substrate for biomolecule conjugation, a "signal-off" sandwich-type PEC biosensor was proposed for DNA methyltransferase (Dam MTase) activity detection based on gold nanoparticles (Au NPs) as quenchers.

Bandgap-Tunable Preparation of Smooth and Large Two-Dimensional Antimonene.

Angew Chem Int Ed Engl 2018 07 12;57(28):8668-8673. Epub 2018 Jun 12.

College of Optoelectronic Engineering, Key Lab of Optoelectronic Devices and Systems of Ministry of Education/Guangdong Province, Shenzhen University, Shenzhen, 518060, China.

As a highly stable band gap semiconductor, antimonene is an intriguing two-dimensional (2D) material in optoelectronics. However, its short layer distance and strong binding energy make it challenging to prepare high-quality large 2D antimonene; therefore, its predicted tunable band gap has not been experimentally confirmed. Now, an approach to prepare smooth and large 2D antimonene with uniform layers that uses a pregrinding and subsequent sonication-assisted liquid-phase exfoliation process has been established.
