The ubiquitous presence of porphyrins in nature is a testament to their versatility and utility. This thesis examines the utility of novel synthetic porphyrin derivatives, metallo-pyrolipid, as surface-enhanced Raman scattering (SERS) contrast agents for molecular imaging and monitoring of photodynamic therapy (PDT).…
Abstract The analysis of thin layers in semiconductor components represents a central point in the quality control of semiconductor companies. Not only to control production processes, but to successfully operate also reverse engineering, reliable thin-film measurement methods are essential. In this work, non-destruct…
This thesis presents optical studies of several low-dimensional electronic materials. Reflectance, transmittance, ellipsometry and Raman scattering were employed to measure the fundamental excitations of the materials under study. The electrodynamics of BSCCO two-dimensional atomic crystals were investigated as a func…
Current recombinant BMP-2 (BMP) bioimplants use an acellular collagen sponge (ACS) as a carrier. However these bioimplants produce a large initial burst of BMP which is linked to ectopic bone formation, inflammation and cancer.The objective of this thesis was to evaluate a novel 4-phase scaffold (4PS) as a BMP carrier…

Binary transition metal oxide CoFe2O4 as a high capacity anode material for lithium-ion batteries with the microflower/nanosheet hierarchical structure was synthesized by layered double hydrotalcite-like precursors. The CoFe2O4 and reduced graphene oxide（rGO）coated CoFe2O4(CoFe2O4/rGO) materials were characterized by…

En el presente trabajo se utilizó un heteropoliácido de estructura tipo Preyssler (H14NaP5W30O118), másico e incluido en matriz de sílice obtenida por sol-gel, como catalizador en la síntesis de bajo impacto ambiental de heterociclos nitrogenados correspondientes a las familias de: azlactonas, 1,4-dihidropiridinas, he…
The dehydration of MgCl2 center dot 6H(2)O in MgCl2 center dot 6H(2)O-NH4Cl-KCl system was investigated. The dehydration process was characterized by X-ray diffraction and chemical analysis. The dehydration effects of MgCl2 center dot 6H(2)O in different systems were compared. The dehydration mechanism of MgCl2 center…
Technologically simple and low-cost method is suggested for processing of wastes from manufacture of ionol, a resin from the rectification stage, by isolation of 4,4′-ethylenebis(2,6-di- tert -butylphenol) via dissolution in hexane with the subsequent crystallization. A high activity of the product as a stabilizer of…
Phase formation upon the interaction of thin Yb1 − x Sm x Te (x = 0.02) and As2Te3 films obtained through their simultaneous and successive evaporation is studied. It is shown that the Yb1 − x Sm x As4Te7 phase is formed upon interaction of the thin films at a temperature of 473 K and the Yb1−x Sm x As2Te4 phase at 50…

以Ti/IrO2为阳极，通过实验研究了电化学氧化法对2，4，6-三硝基-1，3，5-苯三酚（TNPG）的去除效果，同时考察了电流密度、极板间距、电解质浓度、TNPG初始浓度等运行参数对TNPG处理效果的影响。研究结果表明，电化学氧化法可以有效去除水中的TNPG，最佳运行工艺条件为电流密度20 mA/cm2、极板间距10 mm、NaCl质量浓度0.3 g/L、Na2SO4质量浓度0.5 g/L。在最佳运行条件下，当TNPG初始质量浓度为400 mg/L时，电解240 min，溶液COD去除率为65.4%；当TNPG初始质量浓度为50 mg/L时，电解80 min，溶液COD去除率为100%。
Fourier transform infrared (FTIR) spectra of 2,3-dichloropyrazine in the region 400-4000 cm(-1) were measured under solid state condition using KBr pellets method and liquid state by the melting method, besides, a Fourier transform Raman (FT-Raman) spectra in region 600-4 000 cm(-1) was recorded. Then equilibrium geom…
We investigate plasmonic structures in nitride-based materials for far-infrared (IR) applications. The two dimensional electron gas (2DEG) in the GaN/AlGaN material system, much like metal- dielectric structures, is a patternable plasmonic medium. However, it also permits for direct tunability via an applied voltage.…
Abstract : The Stockpile Sizing Module (SSM) is a modeling tool used to estimate U.S. shortfalls of strategic and critical materials during a national emergency scenario. This annotated briefing is intended to train a new user on basic operation of SSM. It is designed to be used in conjunction with a training version…
