The primary objective of this research is to develop and verify a methodology for modeling three dimensional discrete crack growth in concrete and reinforced concrete structures. Two main sources of damage, considered in this work, include the mechanical loading and the chemical interaction. The behavior of concrete i…
Data from PhD thesis work of Dr Laurie Little, on the nucleation and growth of crystals of glycine from aqueous solution in the presence of NaCl. Main aim is look at the competing nucleation of two crystal polymorphs (alpha and gamma polymorphs) of glycine. Each experiment is a sequence of images of a 96-well plate. E…
Title: System Behavior Factors For Composite And Mixed Structural Systems (NEES-2007-0440) Year Of Curation: 2011 Description: This project is a NEESR-II award with the aim of developing system behavior factors for frames with steel beams and composite beam-columns (composite frame system). This research also intends…
The present study investigated the hydrogen-related fracture behavior under stress concentration in a low-carbon martensitic steel. Double-notched sheet-type specimens with different diffusible hydrogen contents were prepared, and tensile tests were performed until just before the fracture for observing the crack init…

Ring rolling is a process for creating seamless ring-shaped components using specialized equipment and forming process because of its technological superiorities of high quality, high efficiency and low consuming in energies and materials
With the advance of Massively Parallel Computers usage, the interconnect technology overcomes the limitations of communication as a new concept. One of the most significant challenges in this concept is suitable architecture for these networks’ applications. Recently, x-Folded TM architecture was introduced as a desir…
Herein, the efficiency of Eucalyptus camaldulensis leaves as biosorbent for lead and copper was investigated. The particle size distribution was determined by Granulometric analysis and the functional groups were identified by FT-IR spectroscopy. The effects of contact time, pH and initial metal ions concentration wer…
To extend the wear lives of tribomaterials, the proper control of wear rate is desired. The description of wear rates is shown at the first portion. The fundamental wear mechanisms for rubbers and polymeric materials, such as abrasive wear and adhesive wear, are explained in this paper.

A plethora of work has been done in the area of nanoparticles of late due to the fact that chemists (and physicists) have discovered that the properties of nanoparticles differ from both those of the bulk material and the atoms themselves. Nanoparticles have become of high interest for the use as catalysts while mater…
以硫酸氧钛、二水合乙酸锌、氢氧化钠为原料，研究了不同的滴加方式对NAC—FAS工艺制备ZnO-TiO2复合纳米晶的影响，利用x射线衍射仪（XRD）、透射电子显微镜（TEM）对样品的结构、形貌进行了表征。结果表明：通过NAC-FAS工艺预制TiO2纳米晶可以制备得到复合ZnO—TiO2纳米晶，其平均粒径为15nm，复合纳米晶呈球状。通过NAC-FAS工艺直接滴加反应溶液，不能制备得到ZnO—TiO2，只能制备得到单一晶相或非晶相。
The goal of this research was to study the electrochemical behavior of tri-nuclear clusters of molybdenum and tungsten. In addition, the feasibility of using these clusters as catalysts for the purpose of oxidizing ethanol was investigated. Four tri-nuclear cluster compounds were studied: hexa-Mu2-acetatotriaquadi-Mu3…
A mucopolissacaridose tipo I (MPS I) é uma doença autossômica recessiva causada pela deficiência da enzima α-L-iduronidade (IDUA). Essa deficiência resulta no acúmulo de glicosaminoglicanos levando a diversas manifestações clínicas. A microencapsulação de células recombinantes que superexpressam IDUA tem sido consider…
Tetrahedral amorphous carbon ( ta-C) films were deposited with filtered cathodic vacuum arc by changing the substrate bias from 0V to 500V. The fraction of the sp 3 bonding will be effected by the substrate bias, and the sp 3 fraction is about 85% when the substrate bias is -200V. The RMS of the films decreases with t…
Biomolecular decorated surfaces have shown great potential in many applications ranging from antimicrobial coatings to biosensing and biofuels due to their excellent properties. The performance of such biomolecular functionalized surfaces is largely dependent on the molecular structure of surface immobilized biomolecu…
A novel lanthanide-nitronyl nitroxide compound Dy (hfac)3(NTT-Ph-4-OH)2 (1) has been successfully synthesized by the reaction of NTT-Ph-4-0H with Dy (hfac)3. Single crystal X-ray crystallographic analysis reveals a mononuclear coordination of complex 1. The magnetic studies reveal that complex 1 shows very weak ferrom…
