Nanoporous silicon powder was produced via efficient magnesiothermic reduction. In this work, the thermal effect and reduction process time were investigated on the porous silicon structure. The nanoporous silicon powders were characterized by  X-ray diffraction analysis and field emission scanning electron microscopy. The results demonstrate that porous structure was changed to homogeneous and...

In this paper, the morphology of chemically etched silicon with various concentration  is reported. The surface of Silicon (100) has pyramidal structures which can be used for anti-reflection applications in solar cells. Pyramidal structures can capture incident sun light therefore can enhance the efficiency of silicon solar cells. The structure of silicon pyramid was studied using scanni...

coronary artery disease (cad) is the leading cause of mortality in many parts of the world. genome-wide association studies (gwas) have identified several genetic variants associated with cad in low-density lipoprotein receptor (ldlr) locus. this study was evaluated the possible association of genetic markers at ldlr locus with cad irrespective to lipid profile and as well as the association of...

one of the important factors which should be considered in (coronary artery disease) cad cases is increased carotid intima-media thickness (imt) which has been considered to be associated with coronary artery disease severity and cardiovascular events. the goal of this study was to compare risk factors and carotid imt in cases with cad and healthy subjects and to determine the association betwe...

background: nutrition is among the most important factors influencing coronary artery disease. objectives: here we aimed to study the nutritional status of patients with and without coronary artery disease (cad). patients and methods: we performed a cross-sectional study on 600 patients referred to a cardiology clinic with the signs of acs. the patients were then classified in to two groups (ca...

although coronary artery disease (cad) is not common among individuals younger than 40-45 years of age, a small percentage of this age group needs to undergo surgical revascularization because of cad. why some people are at higher risk of developing premature cad is not clearly known. increased number of traditional risk factors or genetic predisposition may play significant roles in this regar...

background: given gender differences in the risk of coronary artery disease (cad), the present study sought to investigate these dissimilarities amongst patients who underwent angiography at a major, tertiary heart hospital in iran. methods: between 2005 and 2010, 44,820 patients who underwent coronary angiography were enrolled in a registry. pre-procedural data such as demographics, cad risk f...

genome-wide association studies (gwas) have identified genetic variants contributing to the risk of cardiovascular disease (cvd) at the chromosome 9p21 locus. the chromosome 9p21 is an important susceptibility locus for several multifactorial diseases like ischemic stroke, aortic aneurysm, type 2 diabetes mellitus and coronary artery disease (cad). f7 gene because of its role in activating the ...
