Graphene is a 2D material with atomic thickness and possesses unusual thermal, electrical, optical, and mechanical properties. However, those predicted, or measured, material properties could be achieved only when graphene has low defects with controlled surrounding environments. In this presentation, I will introduce two major strategies of graphene synthesis from my group; nonoxidized graphen...

S uperficial venous pathology describes a spectrum of disease related to an underlying dysfunction of the venous system due to either reflux or obstruction. Although rarely life threatening, chronic venous disease (CVD) presents a significant burden both to those affected and to society. It is highly prevalent, with spider veins, varicose veins, and chronic venous ulceration (CVU) affecting up ...

Amorphous SiO(2) membranes were prepared via a 2-step plasma-enhanced CVD (PECVD) technique at room temperature on porous TiO(2)/Al(2)O(3) substrates. SiO(2) membranes showed molecular sieving properties with a high separation factor for He/N(2) and He/H(2), and high thermal stability, indicating the successful preparation of high-performance membranes at low temperatures.

Abstract Objective . Infrared thermography has the potential to complement classification of chronic venous diseases (CVD), but lacks sophisticated insights on association between recorded skin temperatures and severity CVD. This research aims identify temperature patterns in lower legs patients that are distinct specific forms CVD, including florid ulcers. Approach images were acquired a clini...

Silicon carbide (SiC) films produced on Si substrates by the thermal chemical vapor deposition (CVD) method using methylsilane (MS) were compared with those made mass-selected ion-beam (MSIBD) MS-derived 100 eV SiCH 5 + ions. We also investigated effect of ion injections during CVD process. When substrate was 550 °C, no distinct peaks found in Fourier transform infrared (FTIR) spectroscopy spec...

protein- energy malnutrition, wasting and inflammation are frequent complication among patients with end-stage renal disease (esrd). malnutrition is associated with cardiac co-morbidity, inflammation and poor survival in esrd patients. serum albumin is a well-known marker of nutrition in esrd patients. serum albumin is still the most commonly used nutritional marker in esrd patients. c-reactive...
