Structure and photovoltaic properties of Ag/p-CuPc/a-Si/c-Si/Ag organic-inorganic hybrid heterojunction fabricated by chemical spray pyrolysis technique
(Elsevier Science Bv, 2013)
This investigation refers to the fabrication of an organic-inorganic hybrid heterojunction photovoltaic device. Heterojunctions PV devices were fabricated by growing p-type organic CuPc films onto inorganic amorphous silicon ...
Low temperature crystallization of amorphous silicon by gold nanoparticle
(Elsevier, 2013)
Single crystalline Si thin film fabricated on glass substrate by a process called Solid Phase Crystallization (SPC) is highly desirable for the development of high efficiency and low cost thin film solar cells. However, ...
Characterization of one-step deposited Cu2ZnSnS4 thin films derived from a single crystalline powder
(Pergamon-Elsevier Science Ltd, 2019)
In this paper, Cu-deficient and Zn-rich Cu2ZnSnS4 (CZTS) single crystals were successfully grown by Bridgman technique. Following the investigation of structural and photo-electrical properties of the grown CZTS crystal, ...
Improvement in electrical and photovoltaic properties of a-Si/c-Si heterojunction with slanted nano-columnar amorphous silicon thin films for photovoltaic applications
(Elsevier Science Bv, 2015)
The flat a-Si and slanted nanocolumnar (S-nC) a-Si thin films were prepared on c-Si and corning glass substrates by e-beam physical vapor deposition (EB-PVD) technique. The structural properties of all the grown thin films ...
Electrical properties of FePc organic semiconductor thin films obtained by CSP technique for photovoltaic applications
(Elsevier Sci Ltd, 2015)
Iron-phthalocyanine (FePc) organic semiconductor thin films were prepared on Corning glass and c-Si substrates at a substrate temperature of 150 degrees C by a chemical spray pyrolysis (CSP) technique. The structural ...
Key Role for Activin B in Cellular Transformation after Loss of the von Hippel-Lindau Tumor Suppressor
(Amer Soc Microbiology, 2009)
The von Hippel-Lindau tumor suppressor gene (VHL) is mutated in clear cell renal cell carcinomas (RCC), leading to the activation of hypoxia-inducible factor (HIF)-mediated gene transcription. Several VHL/HIF targets, such ...
Effects of calcium hydroxide and N-acetylcysteine on MMP-2, MMP-9, TIMP-1 and TIMP-2 in LPS-stimulated macrophage cell lines
(Walter De Gruyter Gmbh, 2018)
Aim: This study was evaluated the effects of N-acetylcysteine (NAC) and calcium hydroxide (Ca(OH)(2)) on the expression levels of matrix metalloproteinase -2, -9 (MMP-2, -9) and tissue inhibitor metalloproteinase -1, -2 ...
Relationship between reticuloendothelial systems' FDG uptake level and clinicopathological features in patient with invasive ductal breast cancer
(Springer-Verlag Italia Srl, 2017)
The reticuloendothelial system (RES) is a part of the immune system and plays a major role in the protection of against diseases. We thought that FDG-PET/CT may show the degree of systemic immune response induced with ...
Serum Fetuin-A Levels in Patients with Bilateral Basal Ganglia Calcification
(Elsevier Ireland Ltd, 2018)
Background and Purpose: The idiopathic basal ganglia calcification (Fahr syndrome) may occur due to senility. Fetuin-A is a negative acute phase reactant which inhibits calcium-phosphorus precipitation and vascular ...
Analyzing the economic development-driven ecological deficit in the EU-15 countries: new evidence from PSTR approach
(Springer Heidelberg, 2022)
This paper empirically analyzes the non-linear effect of economic activities on ecological balance indicators that estimate the balance between economies' pressure on nature and the biologically productive resource areas ...
