Contrast enhanced magnetic resonance angiography (MRA) with gadolinium containing contrast media has evolved to a standard non-invasive imaging modality. High quality 3D vessel reconstructions can be acquired using conventional MR scanners together with body surface coils and 3D gradient sequences. The predominant ind…
Objective—To test the therapeutic activity of perivascular transplantation of encapsulated human mesenchymal stem cells (MSCs) in an immunocompetent mouse model of limb ischemia. Approach and Results—CD1 mice underwent unilateral limb ischemia, followed by randomized treatment with vehicle, alginate microbeads (MBs),…
Background—Although methods for generating cardiomyocytes from pluripotent stem cells have been reported, current methods produce heterogeneous mixtures of cardiomyocytes and noncardiomyocyte cells. Here, we report an entirely novel system in which pluripotent stem cell–derived cardiomyocytes are purified by cardiomyo…
Square planar d8 platinum(II) complexes and octahedral d6 iridium(III) complexes were synthesized. Their photophysics were studied in detail. Structure-property relationship was studied by varying the substitution on the ligands or the ?-conjugation extent of the ligands. In Chapter 2, bipyridyl platinum(II) bisstilbe…
Utilizing wood as filler and reinforcement in thermoplastic polymer-matrix composites, has gained interest during the last decades, mainly as profile extruded exterior building products such as deck boards, railings, and door- and window frame components. This thesis deals with silane-crosslinking of wood-polyethylene…
The use of nanotechnology in pharmaceutical development has progressed significantly in recent decades. This rapid advancement is driven by crucial need for improving the performance of present diagnostic and therapeutic modalities, as well as development of a new class of delivery systems for complex entities such as…
Predicted exhaustion of the petroleum resources and global pollution of the environment force the society to establish new environmental regulations and introduce new materials from renewable resources that will assure sustainable development. One of those eco-friendly materials is poly(L-lactide) (PLLA). PLLA is a bi…
Genetic evaluation of mastitis liability and recovery through longitudinal models of simulated SCC
The Glen Helen Diatom handbook describes several species of microscopic algae found in the Yellow Springs Creek that runs through the Glen Helen Nature Preserve. The 1000-acre Preserve in Yellow Springs, Ohio has facilities for recreation, education, and research. The handbook describes diatom biology and the associat…
The layered piezoactuators used in mechanisms requiring high precizion displacements have indicated that accuracy depends on design and technological factors. One of essential requirements for compound piezoactuators is their capability of transferring unipolar or bipolar force. In the first version, the piezoactuator…
A celulose é o polissacarídeo mais abundante na Natureza, sendo o principal componente estrutural das plantas, e com uma importância industrial elevada principalmente na indústria papeleira e têxtil. Para além das plantas, a celulose é também produzida por algumas bactérias sendo designada de celulose bacteriana (BC).…
探讨负载型金属氧化物催化剂的表面组分与载体之间的相互作用,有助于理解相关催化剂的催化作用本质.近年来,我们对单组分CuO以及双组分CuO-Mn2O3,CuO-CoO等金属氧化物在γ-Al2O3载体表面的分散行为和存在状态,及其物理化学性质和催化性能(CO+O2和NO+CO模型反应)进行了研究.结果表明,这些金属氧化物在γ-Al2O3载体表面的分散行为和所得负载型催化剂样品的一些物理化学性质及其催化性能均可参照'嵌入模型'来解释.在此基础上,我们讨论了这些样品的'组成-结构-性质'间的关系,并针对表面负载双组分金属氧化物样品提出了表面协同氧空位参与的NO+CO反应机理.
Amorphous carbon (a-C) is expected to be an excellent material for fabricating low cost and high efficiency carbon based solar cells because of its interesting properties and feasibility of band gap engineering over a wide range. The preparation of a-C thin films was carried out by using thermal chemical vapor deposit…
In the present word we have studied the effect of temperature on the Raman spectra of crystals of L-alanine + oxalic acid, C3H8NO2+.C2HO4-. Raman spectroscopy measurements were performed on polycrystalline samples at different temperatures varying in the range from room temperature to T = 20 K; a tentative assignment…
The aim of the present study was to develop a system of 17-β estradiol (E2) loaded poly (lactic-co-glycolic acid) PLGA nanoparticles-chitosan/hydroxyapatite (HA) tissue scaffold and to investigate the in-vitro effectiveness of this system in adipose derived mesenchymal stem cell (AdMSC) cultures for bone tissue regene…
Detailed Study of Distribution Patterns of PAHs and Isocyanates under Different Fire Conditions
In the field of renewable materials, natural fiber composites demonstrate the capacity to be a viable structural material. When normalized by density, flax fiber mechanical properties are competitive with E-glass fibers. However, the hydrophilic nature of flax fibers reduces the interfacial bond strength with polymer…
We studied the thermal and electron properties of covalent one-dimensional (1D) monatomic linear chains of carbon, particularly carbyne. We found the ${\alpha}$ -carbyne (Polyyne, alternating single and triple C-C bond co-existing) is more stable than ${\beta}$ -carbyne (Equally-spaced based on ...
The reliability of plant components made of polymers makes a significant contribution in the steel industry to the efficiency of pickling lines, as well as to occupational safety and environmental ...
