Enhanced electrical and optical properties of single- layered MoS2 by incorporation of aluminum

引用

Nano Research 2018年第2期11卷 731-740页

作者： kim, Hyung-Jun Yang, Suk kim, Hojoong Moon, Jin Young Park, Kyung Park, Yun-Jin Kwon, Jang-yeon School of Integrated Technology Yonsei University Incheon Republic of Korea Yonsei Institute of Convergence Technology Incheon Republic of Korea

Electrical and optical enhancements of single-layer semiconducting materials such as transition metal dichalcogenides have recently been studied to achieve sensitive properties via external treatments, such as the formation of organic/ inorganic protecting layers on field-effect transistors （FETs）, thermal annealing, and nano-dot doping of sensors and detectors. Here, we propose a new analytical approach to electrical and optical enhancement through a passivation process using atomic layer deposition （ALD）, and demonstrate a synthesized MoS2 monolayer incorporated with A1 atoms in an A1203 passivation layer. The incorporated A1 atoms in the MoS2 monolayer are dearly observed by spherical aberration-corrected scanning transmission electron microscopy （Cs-STEM） and TEM-energy-dispersive X-ray spectroscopy results. We demonstrate that the chemically incorporated FETs exhibit highly enhanced mobilities of approximately 3.7 crn2-V-los-1, forty times greater than that of as-synthesized MoS2, with a three- fold improvement in the Dhotoluminescence properties.

Krill oil ameliorates benign prostatic hyperplasia by regulating G-phase cell cycle arrest and altering signaling pathways and benign prostatic hyperplasia-associated markers

Krill oil (KO) exhibits various biological activities， such as anti-inflammatory and antitumor effects. However， the inhibitory effects of benign prostatic hyperplasia (BPH) in vitro and in vivo have not yet been studied. This study investigated the anti-BPH effects of KO extracted by an enzymatic hydrolysis method. KO treatment inhibited the proliferation of WMPY-1 and BPH-1 cells by induction of G0/G1phase arrest through the modulation of positive and negative regulators in both prostate cell types. KO treatment stimulated phosphorylation of JNK and p38 signaling. In addition， KO changed the expression of BPH-related markers (5α-reductase， androgen receptor， FGF， Bcl-2， and Bax) and the activity of the proliferation-mediated NF-κB binding motif. KO-induced levels of proliferation-mediated molecules of prostate cells were attenuated in the presence of siRNA-specific p-38 (si-p38) and JNK (si-JNK). Furthermore， the administration of KO alleviated prostate size and weight and the cell layer thickness of prostate glands in a testosterone enanthate-induced BPH rat model. KO treatment altered the level of dihydrotestosterone in serum and the expression levels of BPH-related markers in prostate tissues. Finally， KO-mediated inhibition of prostatic growth was validated by histological analysis. These results suggest that KO has an inhibitory effect on BPH in prostate cells in vitro and in vivo. Thus， KO might be a potential prophylactic or therapeutic agent for patients with BPH.

Regeneration of pure water is an important issue not only for the healthy life but also for the fine control of precise processes in various *** important issue in ultrahigh purified water is to reduce the amount of total organic carbon(TOC).Herein,we introduce a new approach to reduce the TOC using the surface silanized nanoparticles,in which the magnetic nanoparticles(mNPs)are silanized and then complexed with ion exchange resin(IER)*** Fe3O4 mNPs are surface modified by using high concentrated vinyltrimethoxysilane(VTMS)and then adhered on the surface of IER *** surface modified mNPs have a thick-shell of polysiloxane layer varying from 5 to 22 nm depending on the amount of VTMS used,which leads the significant increase of specific surface *** IER beads embedding VTMS-silanized mNPs achieves about 7μg/L of the TOC level in ultrapure water system,which is two orders less than 228μg/L of the feeding water and one order less than 96μg/L from the system using pristine IER *** result is mainly attributed to the polysiloxane layer forming broccoli-like surface structure and some part by the vinyl group of VTMS exposed to the amines in the water.
