Concerns on environmental waste problems caused by non-biodegradable petrochemical-based plastic packaging materials as well as the consumer's demand for high quality food products has caused an increasing interest in developing biodegradable packaging materials using annually renewable natural biopolymers such as pol…
MolProbity is a general-purpose web server offering quality validation for 3D structures of proteins, nucleic acids and complexes. It provides detailed all-atom contact analysis of any steric problems within the molecules as well as updated dihedral-angle diagnostics, and it can calculate and display the H-bond and va…
Abstract An analysis and simulation of the gouging impact phenomenon which occurs at the Holloman Air Force Base High Speed Test Track (HHSTT) during hypervelocity impact testing is presented. Simulations of the sled/rail interactions were conducted using the hydrocode, CTH. These simulations utilize the most accurate…
The stress corrosion cracking (SCC) of three austenitic stainless steels was investigated as a function of test temperature and applied stress in boiling saturated magnesium chloride solutions (MgCl 2 ) using a constant load method. Both type 304 and type 316 exhibited similar corrosion elongation curves, while the co…
[Abstract] This paper develops a new method to create a galvanic corrosion-resistant CFRP/Al-FRML based on nano-composite coating. Nano-composite coating consists of a sulfuric acid anodizing and a silica nano-particle reinforced hybrid sol-gel coating and is conducted on the surface of Aluminum alloy 2024-T3 to preve…
The extremely radioresistant bacterium Deinococcus radiodurans is evolutionarily closely related to the extremely thermophilic bacterium Thermus thermophilus. These bacteria have a single gene encoding an aspartate kinase (AK) that catalyzes the phosphorylation of L-aspartate. T. thermophilus has an aminoadipate pathw…
Metallic foams and honeycombs, with their light-weight, high speciflc stifiness, and well-developed energy absorption characteristics, are of obvious utility in engineering applications. However, these structures, often made of aluminum, sufier permanent deformation after crushing. Cellular structures made from shape-…
Abstract Composites prepared at 200°C by the melt compounding of copolymer polyamide 6/66 and ferric chloride, ferric oxalate, cupric chloride, cupric formiate, cupric acetate, Cr‐carbonyl, Mo‐carbonyl, or W‐carbonyl have been studied. The solution stability and aggregation suppression for nanoparticles in a polyamide…
Abstract The oxidative polycondensation reaction conditions of N,N′ ‐bis[(2‐hydroxy‐1‐naphthyl)methylene]urea (2‐HNMU) has been accomplished using NaOCl, H 2 O 2 , and air O 2 oxidants in an aqueous alkaline medium. The structures of the obtained monomer and oligomer were confirmed by FTIR, UV–vis, 1 H NMR, 13 C NMR,…
Abstract The effects of melt blending conditions on the rheology, crystallization kinetics, and tensile properties of phosphate glass/polyamide 12 hybrid systems were investigated for the first time, to understand their complex processing/structure/property relationships. Increasing amounts of phosphate glass (Pglass)…
Abstract A halogen atom terminated Polystyrene (PSt) was prepared by means of atom transfer radical polymerization. Then, the halogen atom was converted into ‐N 3 group and a ‐N 3 terminated PSt was obtained. Finally PSt was grafted onto the surface of single walled carbon nanotube (SWNT) by the reaction of azide grou…
Abstract Preparation of superhydrophobic silica‐based films via sol‐gel process by adding polyethylene glycol (PEG4000) in the silica sol precursor solution has been developed. The casting films were prepared by casting the above solution on the glass and adding poor solvent on it or not. Surface roughness of the film…
Experimental observations of peculiar time-dependent charge transport phenomena, such as slow conductivity relaxation, nonergodicity, and simple aging, are reported here for mesoporous silicon at room temperature. These effects are discussed on the basis of the strong disorder in the nanocrystalline silicon network co…
Abstract Different crystallization kinetic models (Avrami and Tobin) have been applied to study the crystallization kinetics of virgin poly(butylene terephthalate) (PBT) and filled PBT systems under isothermal experimental conditions. The experimental data have been analyzed with a nonlinear, multivariable regression…
(Abstract) We lay out the metallurgical basis for a new and robust method for joining NiTi shape-memory and superelastic alloys. It is based on the use of pure niobium as a melting-point depressant that can induce contact melting with NiTi at tractable temperatures. A strong, ductile, corrosion-resistant, biocompatibl…
Fluorine-terminated chemical bonds and dipole structures within an Al2O3 layer were investigated in this study. Spectroscopic ellipsometry (SE) was employed to estimate the characteristics of fluorinated Al2O3. The parameters S0 and λ0 extracted from SE were analyzed to detect the influence of F-terminated bonding. Al…
The growth dynamics of ZnO epilayers by metal-organic chemical vapor deposition have been investigated by a comprehensive modeling of the competitive adsorption and two-site occupation effects. The established model, based on Langmuir-Hinshelwood mechanism, well explains the abnormal growth rate dependence on the VI/I…
Optical properties of colloidal II-VI semiconductor CdSe cores with ZnS and CdS multishell quantum dots (QDs) have been studied by experimental characterization and theoretical analysis. Due to the large number of energy states densely compacted in both conduction and valence bands of the quantum dots, strong interban…
Utilizing titanyl sulfate as a TiO2 source, via a novel synthesis method—the detonation method—nanosized TiO2(n-TiO2) powders were prepared. The results showed that the as-prepared n-TiO2 powders did not have enough time to grow into large and fine crystallites, and that the characteristics of high temperature, high p…
Self-assembly of a nanotube forming molecule, hexa-peri-hexabenzocoronene (hbc), in aqueous solution is studied using a coarse-grain (CG) force-field in molecular dynamics (MD) simulations. The simulations yield details of the pre-aggregation regime, which is generally inaccessible to experimental studies. The simulat…
