Kink-Based Path Integral Calculations Of Atoms He-Ne, Randall W. Hall

Randall W. Hall

An adaptive, kink-based path integral formalism is used to calculate the ground state energies of the atoms He–Ne. The method uses an adaptive scheme to virtually eliminate the sign difficulties. This is done by using a Monte Carlo scheme to identify states that contribute significantly to the canonical partition function and then include them in the wavefunctions to calculate the canonical averages. The calculations use the 6-31G basis set and obtain both precision and accuracy.

Improvement Of Mechanical Properties And Water Stability Of Vegetable Protein Based Plastics, Gowrishankar Srinivasan

Gowrishankar Srinivasan

Bio-renewable bio-degradable plastics are a potential solution to the growing problems of pollution caused by petroleum plastics and dependency on foreign nations for petroleum resources. One possible feed stock for these materials are vegetable proteins, especially from soy bean and corn. These proteins have relatively high molecular weights and have the potential of being processed with standard polymer processing technologies. But some issues that need to be addressed are their water instability (soy protein) and inferior mechanical properties as compared to petroleum derived plastics. In this study, soy protein isolates (SPI) and zein protein was processed with various additives and …

Multiscale Modeling, Simulations, And Experiments Of Coating Growth On Nanofibers. Part I. Sputtering, A. Buldum, I. Busuladzic, C. B. Clemons, L. H, Dill, K. L. Kreider, G. W. Young, Edward A. Evans, G. Zhang, S. I. Hariharan, W. Kiefer

S. I. Hariharan

This paper is Part I of an integrated experimental/modeling investigation of a procedure to coat nanofibers and core-clad nanostructures with thin-film materials using plasma-enhanced physical vapor deposition. In the experimental effort, electrospun polymer nanofibers are coated with aluminum under varying operating conditions to observe changes in the coating morphology. This procedure begins with the sputtering of the coating material from a target. This paper focuses on the sputtering process and transport of the sputtered material through the reactor. The interrelationships among the processing factors for the sputtering and transport are investigated from a detailed modeling approach that describes the salient …

Electrically Conductive Polyaniline Sensitized Defective-Tio2 For Improved Visible Light Photocatalytic And Photoelectrochemical Performance: A Synergistic Effect, M O. Ansari, Mohammad Mansoob Khan Dr, S A. Ansari, M H. Cho

Dr. Mohammad Mansoob Khan

Sulfonated polyaniline@pure-TiO2 (s-Pani@p-TiO2) and polyaniline@defective-TiO2 (s-Pani@m-TiO2) nanocomposites were prepared by the in-situ oxidative polymerization of aniline in the presence of TiO2 (p-TiO2 and m-TiO2) nanoparticles followed by sulfonation with fuming sulfuric acid. Defect-induced TiO2 (m-TiO2) nanoparticles were obtained by an electron beam (EB) treatment of commercial TiO2 (p-TiO2) nanoparticles. The resulting s-Pani@p-TiO2 and s-Pani@m-TiO2 nanocomposites were characterized by UV-visible diffuse absorbance spectroscopy, photoluminescence spectroscopy, transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. Polyaniline (Pani) was dispersed uniformly over the defective m-TiO2 surface with intimate contact on the interface to act cooperatively with the defects introduced deliberately to achieve remarkably …

Determination Of Total Peroxide Content In Secondary Organic Aerosol Particles, Matthew E. Wise

Matthew E. Wise

Secondary organic aerosol particles (SOA) formed from the oxidation of monoterpenes can impact the Earth’s radiation balance, act as cloud condensation nuclei and negatively affect human health. In the initial Visiting Faculty Program application, we proposed the use of an ultraviolet-visible spectrometer equipped with a liquid waveguide capillary flow cell to determine the extent to which SOA absorb visible light. The inclusion of Concordia University in the Secondary Organic Aerosol From Forest Emissions Experiment (SOAFFEE) laboratory campaign at PNNL necessitated a change in the proposed experiments. An iodometric-spectrophotometric (IS) technique was developed to quantify the total peroxide content in SOA. …

Biogenic Synthesis Of A Ag–Graphene Nanocomposite With Efficient Photocatalytic Degradation, Electrical Conductivity And Photoelectrochemical Performance, Mohammad Mansoob Khan Dr, Mohammad Ehtisham Khan, M. H. Cho Prof

Dr. Mohammad Mansoob Khan

This paper reports the environmentally benign, simple, cost efficient, one-step, surfactant free, and biogenic synthesis of silver-graphene (Ag-Graphene) nanocomposite using an electrochemically active biofilm (EAB). The EAB was used for the reduction of Ag+ to Ag0 onto the graphene sheets. The morphology, structure, composition, and optical properties and contact angle of the Ag-Graphene were obtained using a range of techniques which confirmed the anchoring/presence of silver nanoparticles (AgNPs) onto the graphene sheets. The photocatalytic activity of the Ag-Graphene was evaluated by the degradation of methylene blue and Congo red dye in aqueous solution at an ambient temperature in dark and …

Classification And Cluster Analysis Of Complex Time-Of-Flight Secondary Ion Mass Spectrometry For Biological Samples, Stephen E. Reichenbach, Xue Tian, Qingping Tao, Alex Henderson

Steve Reichenbach

Identifying and separating subtly different biological samples is one of the most critical tasks in biological analysis. Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is becoming a popular and important technique in the analysis of biological samples, because it can detect molecular information and characterize chemical composition. ToF-SIMS spectra of biological samples are enormously complex with large mass ranges and many peaks. As a result the classification and cluster analysis are challenging. This study presents a new classification algorithm, the most similar neighbor with a probability-based spectrum similarity measure (MSN- PSSM), which uses all the information in the entire ToF- SIMS …

Using Lectinmicroarrays To Identify Regulatory Mechanisms For Mammalian Glycosylation, John F. Rakus

John F. Rakus

Glycosylation involves the post-translational addition of carbohydrates to protein molecules and is an intricate and indispensable biochemical process. Study of this complicated network of interactions is hindered by the lack of a coding template analogous to the genetic code, and by the vast structural complexity inherent to carbohydrate polymers. We use lectins (non-enzymatic carbohydrate-binding proteins of non-immunological origin) as microarray probes to identify carbohydrate features expressed on cellular surfaces. Specifically, we utilized lectin microarray technology to investigate the differences in carbohydrates expressed by the cell lines of the Nation Cancer Institute’s NCI-60 panel. Our investigation identified tissue-specific expression differences in …

Polythiophene Nanocomposites For Photodegradation Applications: Past, Present And Future, Mohammad Mansoob Khan Dr, M. O. Ansari, S. A. Ansari, M. H. Cho

Dr. Mohammad Mansoob Khan

Polythiophene (PTh) has been the subject of considerable interest because of its good environmental stability, unique redox electrical behavior, stability in doped and neutral states, ease of synthesis, and wide range of applications in many fields. Apart from its applications in the electrical or electronic field, PTh has shown promising applications in photocatalytic degradation. The fabrication of a catalyst, metal oxides with PTh, extends the absorption range of the modified composite system, thereby enhancing the photocatalytic activity under UV or visible light irradiation. Substituted PTh, such as alkyl substitution, modifies the electronic properties of the polymer, thereby enlarging the potential …
