Spin thermoelectricity in dualhydrogenated zigzag silicene nanoribbons with surface adsorptions

Publication date: Available online 9 May 2019Source: Physics Letters AAuthor(s): Yushen Liu, Xiaoshuang Chen, Xifeng YangAbstractThe buckled structure of silicene provides a feasible pathway to influence its electric and magnetic properties via surface adsorptions. Here, we investigate the magnetic and spin thermoelectric transport properties of dual-hydrogenated zigzag silicene nanoribbons (ZSiNRs) without/with the hydrogen adsorption. The band gaps for two spin channels in ZSiNRs under the hydrogen adsorption are shifted near the Fermi level, leading to the appearance of spin Seebeck effect. Using a temperature difference, one can derive the carriers with the different spin index to flow in the opposite direction. Moreover, a large rectification ratio close to 105 at room temperature is achieved for the spin current, and the charge current exhibits a remarkable negative differential thermoelectric resistance (NDTR) behavior. The results presented here are fascinating potential applications in the fields of silicon-based spin caloritronic devices.

CONCLUSIONS: These findings suggest that careful clinical history taking to document specific neurodevelopmental features may be informative in screening for individuals with schizophrenia who are at higher risk of carrying known SCZ-associated CNVs. Identification of genomic disorders in these individuals is likely to have clinical benefits similar to those demonstrated for other neurodevelopmental disorders.

Their structures were established mainly by spectroscopic analyses as well as necessary chemical evidence. All isolated compounds were screened for the cytotoxicity against HepG2 cells, and the results demonstrated that only the kno...

The chemical structures of these new compounds were characterized through extensive spectroscopic analysis and comparison with literatures. Among them, the absolute structures of daturmetesides A and C were unambiguously determined by X-ray crystallography. The anti-inflammatory effect of daturmet...

Incretin peptides, including GLP-1, GLP-2, and GIP, are released from the gastrointestinal tract and have an crucial role in the glucose hemostasis and pancreatic beta-cell function. These hormones and their analogs with a longer half-life, glucagon like peptide-1 receptor a...

This is an efficient and simple sample treatment (with average analyte recoveries between 90% and 104%) involving solvent extraction with hexane followed by evaporation. There is no need for any additional clean-up step, as the matrix did not affect determination of mass spectro...

ConclusionExtracts of H. lippii contain a higher level of phenols compared to the extracts of C. schoenanthus. All extracts of C. schoenanthus and H. lippii caused marked relaxation of the isolated rat distal colon, either when applied directly or when tested over KCl- and Ach-induced precontraction. These results give support to the use of C. shoenanthus and H. lippii in traditional medicine, namely for gastrointestinal diseases.Graphical abstract

ConclusionsThese observations suggest that SYD is effective in the enhancement of antioxidant ability via activation of Nrf2 pathway and the up-regulation of Nrf2-downstream phase II enzymes expression. The anti-inflammation and antioxidant action of SYD together contributes to the prevention and treatment of ulcerrelated colorectal cancer.Graphical abstract
