We present the results of a Raman study of optical phonons in CuS nanocrystals (NCs) with a low areal density fabricated through the Langmuir-Blodgett technology on nanopatterned Au nanocluster arrays using a combination of surface- and interference-enhanced Raman scattering (SERS and IERS, respectively). Micro-Raman spectra of one monolayer of CuS NCs deposited on a bare Si substrate reveal on...

Copper sulfide nanoparticles (CuS) were successfully synthesized by the pulsed plasma in liquid method, using two copper rod electrodes submerged in molten sulfur. Low electrical energy and no high temperature were applied for synthesis. Obtained CuS nanoparticles were then analyzed by means of X-ray diffraction, Low and High Resolution Transmission Electron Microscopy, Electron Diffraction, X-...

Korean credit :::union:::s (CUs) are considered to be a hidden contributor to the “Korean miracle”, characterized by remarkable economic growth and relatively low income inequality. The Korean miracle not only generated wealth in an economically strapped and socially under-privileged people, but also contributed to regional community development and the democratization of Korean society. In...

OBJECTIVES The aim of the study was to compare diagnostic utility of combined (i.e. transbronchial and transoesophageal) ultrasound imaging with needle biopsy of the mediastinum in lung cancer (LC) staging, (a) by use of a single ultrasound bronchoscope (CUSb) and (b) by using two scopes (CUS). METHODS In consecutive LC patients, clinical stage IA-IIIB the CUS or CUSb was performed under mild...

We extracted cucurmosin (CUS) from the sarcocarp of Cucrubita moschata (pumpkin). Recently, a number of studies have indicated that CUS has cytotoxic properties and induces apoptosis in a number of human tumor cells. However, the detailed mechanisms are largely unknown. The aim of this study was to confirm CUS's anticancer activity on human hepatoma HepG2 cells in vitro and in vivo, and to eluc...

The ITO (indium tin oxide) conductive glass-matrix CuS-GeO2-TiO2 composite coating was generated via EPD (electrophoretic deposition) and followed by a sintering treatment at 450°C for 40 minutes. Characterizations of the CuS-GeO2-TiO2 composite coating were taken by SEM (scanning electron microscope), XRD (X-ray diffraction), EDX (energy dispersive X-ray), UV-Vis DRS (ultraviolet-visible diffu...

We present the rational synthesis of nanoporous CuS for the first time by chemical dealloying method. The morphologies of the CuS catalysts are controlled by the composition of the original amorphous alloys. Nanoporous Cu2S is firstly formed during the chemical dealloying process, and then the Cu2S transforms into CuS. The nanoporous CuS exhibits excellent photocatalytic activity for the degrad...

Chronic ulcerative stomatitis (CUS) is a mucocutaneous disorder which is characterised by persistent oral mucosal ulceration. The clinical appearance is often reminiscent of oral lichen planus (OLP) leading to erroneous diagnoses. The immune mediated inhibition of the CUS protein (CUSP) is implicated in the pathogenesis of CUS. CUSP acts as an anti-apoptotic protein and when its action is preve...

BACKGROUND Pancreatic cancer treatment is limited and effective drugs are needed. We investigated cucurmosin (CUS)-induced apoptosis in cystic fibrosis pancreatic adenocarcinoma cells (CFPAC-1) and a possible mechanism of action to evaluate the clinical application potential of this new Type I ribosome-inactivating protein. METHODS We analyzed the growth inhibition and apoptosis of CFPAC-1 ce...

Visible light photocatalytic H(2) production through water splitting is of great importance for its potential application in converting solar energy into chemical energy. In this study, a novel visible-light-driven photocatalyst was designed based on photoinduced interfacial charge transfer (IFCT) through surface modification of ZnS porous nanosheets by CuS. CuS/ZnS porous nanosheet photocataly...
