We explore n-type doping of BiCuSeO, an otherwise well-known p-type thermoelectric material, and find halogens to be the most effective dopants.

in accordance with waste strategy for turkey, the study was carried out to analyses waste engine crankcase oils and waste gearbox oils generated from vehicle maintenance services in order to determine their suitability for recycling, recovery or final disposal based on regulation published by turkish ministry of environment and forestry on 21 january 2004. the regulation requires all waste oil ...

Functionalized X-Bi bilayers (X = Ga, In, and Tl) with halogens bonded on their both sides have been recently claimed to be the giant topological insulators due to the strong band inversion strengths. Employing the first-principles electronic structure calculation, we find the topological band order transition from the order p - p - s of the X-Bi bilayers with halogens on their both sides to th...

The role of halogens in both the marine boundary layer and the stratosphere has long been recognized, while their role in the free troposphere is often not considered in global chemical models. However, a careful examination of free-tropospheric chemistry constrained by observations using a full chemical data assimilation system shows that halogens do play a significant role in the free troposp...

Functionalisation of single-walled carbon nanotubes (SWNTs) with atoms and molecules has the potential to prepare charge–transfer complexes for numerous applications. Here, we used density functional theory dispersion correction (DFT + D) examine encapsulation adsorption efficacy trap halogens. Our calculations show that is exoergic respect gas-phase atoms. The stability inside SWNTs revealed b...
