For most of the active pharmaceutical ingredients, poor aqueous solubility and hence low bioavailability and erratic absorption is the common difficulty observed by the formulation development scientist. Nanotechnology drug delivery has gained much interest as a way to improve the solubility problems. Nanosuspension i…
Non-destructive evaluation techniques were used to assess the condition of a 40-year old concrete bridge operating in an aggressive marine environment. The bridge’s superstructure includes both reinforced and prestressed concrete one-way slabs, and experienced widening, repairs, and recently strengthening by means of…
The susceptibility of MAX phases to thermal dissociation at 1300-1800 °C in high vacuum has been studied using in-situ neutron diffraction. Above 1400 °C, MAX phases decomposed to binary carbide (e.g. TiCx) or binary nitride (e.g. TiNx), primarily through the sublimation of A-elements such as Al or Si, which results i…
Manycore chips are emerging as the architecture of choice to provide power-scalability and improve performance while riding the Moore’s law. On-chip interconnects are increasingly playing a pivotal role in power- and performance- scalability of such microarchitectures. As supply voltages begin to level off in future t…
This doctoral thesis describes the methodological development of coupled neutron-kinetics/thermal-hydraulics codes for the design and safety analysis of reactor systems taking into account the feedback mechanisms on the fuel rod level, according to different approaches. A central part of this thesis is the development…
The sodium-cooled fast reactor (SFR) is one of the options currently being investigated as a future\nGeneration IV reactor. This concept may include minor actinide (MA) recycling in the radial blankets positioned in the\nouter core regions. Heterogeneous recycling on a UO2 matrix has the advantage of providing flexibl…
Polycrystalline ceramic Nd0.7Sr0.3MnO3 is synthesized using high-energy ball milling and post heat treatment method. The properties of electric transport are measured using direct current (DC) 4-wire and 2-wire methods. The results show that both the grain (phase) boundary and the electrode-bulk contact interface has…

The effects of initial temperature and cooling rate on the freezing behaviors of clusters Co531, Cu531, and Ni531 are studied by the molecular dynamics with a general embedded atom method. The results show that their freezing points are obviously influenced by initial temperature and cooling rate. Higher initial tempe…
Light induced degradation caused by boron-oxygen complexes in compensated Czochralski-wafers produced from 50% Elkem Solar Silicon® (ESSTM) and 50% non-compensated polysilicon is studied. Minority carrier lifetimes are measured using QssPC calibrated photoluminescence imaging and illumination with 1 Sun is used to ind…
The objective of the study was to formulate micro particles of a poorly soluble drug Ketoprofen with the aid of Chitosan in presence of salting out agents. Dissolution Studies were carried out in 0.1N HCl using USP type II dissolution apparatus. The effect of Chitosan in presence of salting out agent predominated drug…
The purpose of controlling the quenching process of an orange-hot steel workpiece is to ensure its required surface hardness. A sound in a cooling liquid generated by the quenching process was experimentally analyzed. It contains sufficient information about the ongoing process for its quantification, and it can be us…
Maximizing filler loading in order to improve papermaking economics and optimize paper quality is of continuous interest to the producer of printing and writing papers. Traditionally filler is primarily applied to the sheet in the wet end as so-called internal loading. In the surface filling process one or two percent…
This paper investigates the excited states of Si 3 O molecule by using the single-excitation configuration interaction and density functional theory. It finds that the visible light absorption spectrum of Si 3 O molecule comprises the yellow and the purple light without external electric field, however all the visible…
The ethanolic extract of the roots of Hemidesmus indicus was investigated for its nephroprotective activity in Cisplatin induced renal injury in rats. In the curative regimen, the ethanolic extract at dose levels of 250 and 500 mg/kg showed dose-dependent reduction in the elevated blood urea and serum creatinine. Ther…
This paper aims to investigate the dynamic mechanical properties of Polycarbonate material processed by Fused Deposition Modeling (FDM) rapid prototyping process. Frequency sweep is performed in Dynamic Mechanical Analysis (DMA) 2980 equipment to get modulus, damping and viscosity values. The effects of FDM parameters…
The reflection property of alkaline textured wafers is an important parameter for texture evaluation. Nevertheless, the geometric properties of the surface structure influence cell performance and cannot be distinguished by reflection measurements only. The pyramid size distribution can affect, e.g. contact formation…
In this paper some polyurethane membranes were prepare by electrospraying process to obtain biocompatible materials. The polyurethanes utilized in this study were synthesized from hexamethylene diisocyanate (HDI), polytetramethylene ether glycol (PTMEG) and butanediol (BD) filled with different proportion of hydroxypr…
Microcrystalline Cellulose (MCC) is a very important product in pharmaceutics, foods, cosmetics and other industries. In this study, Beeswing (-20L) and Chaff. (+5) which are the parts of corn cobs were used as raw material to produce MCC via alkaline degradation. The effects of concentration of sodium hydroxide solut…
Zinc Aluminum Oxide (ZAO) thin films were prepared by DC reactive magnetron sputtering on glass substrates and the effect of substrate temperature (from 303K-623K) on the structural and optical properties were studied. XRD patterns of ZAO thin films deposited at different substrate temperatures exhibit (0 0 2) prefere…
