Abstract Castor oil is derived from the bean of the castor plant,Ricinus communis. The seeds of the castor plant are produced in racemes or clusters of capsules. The capsules contain three seeds protected by a hull that is removed prior to processing. Commercial processing of the seed consists of heating the seed, cru…
Abstract Molecular biologists attempt to understand the inner workings of the cell, the smallest unit of all life forms on earth. The constituents that perform cellular functions are the proteins, enzymes and nucleotides. A full appreciation of the chemical and biological functions of the cellular constituents, and th…
The natural world is the source of many therapeutic products. Spider silk was evaluated for its ability to inhibit the growth of bacteria. Additionally tests assessing its potential suitability for use in human medicine were carried out.\n\nSilk produced by certain species of spiders has the ability to inhibit the gro…
This report is the Final Technical Report for the Next Generation Nuclear Plant (NGNP) Prismatic HTGR Conceptual Design Project conducted by a team led by General Atomics under DOE Award DE-NE0000245. The primary overall objective of the project was to develop and document a conceptual design for the Steam Cycle Modul…
Abstract Coating process technology is in widespread use because the surface of most materials needs to be treated in order for the final product to meet all the functional needs and requirements. The modification is accomplished by applying a coating or series of coatings to the material to improve its performance an…
Abstract Homopolymers and copolymers of vinyl fluoride are inert. They possess unique chemical and weather resistance characteristics in addition to good mechanical properties. These polymers have excellent release properties from adhesives such as epoxies. They can also be rendered adherable by flame and corona disch…
Abstract The growth in the use of high pressure by the chemical industry in the 20th Century led to the discovery of polyethylene by ICI in the 1930s. At that time, the pressures required by the large‐scale production of low density polyethylene were well beyond normal design practices for continuously operating plant…
This specification covers biodiesel fuel blend stock, B100, in Grades S15 and S500 for use as a blend component with middle distillate fuels. This specification prescribes the required properties of diesel fuels at the time and place of delivery. The requirements stated here may be applied at other points in the produ…
Abstract This article focuses on organic bromine compounds with industrial application. The organic bromine compounds are prepared and produced either by substitutive or additive bromination. Organic bromine compounds, in which the bromine atom is retained in the final molecular structure, and where its presence contr…
Abstract Cerium, Ce, at. no. 58, is the most abundant member of the series of elements known as the lanthanides.There are few principal lanthanide deposits, and there are no minerals that are sources for cerium alone. Bastnasite and monazite are the two minerals that supply the world's cerium. Production of cerium der…
Abstract Shape‐memory polymers (SMP) are an emerging class of active materials, which are able to change their shape in a predefined way upon appropriate stimulation. SMP, which can switch from a temporary to their permanent shape, are dual‐shape materials. Here fundamental aspects concerning the design of suitable po…
Reactive absorption of CO2 with NaOH as absorbent was evaluated experimentally in a lab scale spray dryer. Taguchi method was used for design of experiments. Results showed that the most important factors are inlet CO2 concentration, nozzle size, absorbent concentration and temperature, respectively. The optimum condi…
In this research work, an attempt has been made to investigate the effect of liquid nitrogen when it was applied to heat generation zones through holes made in the cutting tool insert during the turning of Aluminium 6061 — T6 alloy with uncoated carbide tool. The cryogenic result of the cutting temperature, cutting fo…
This work aims to present a study on 3-Body abrasive wear behavior of ABS plastic on an indigenously developed 3-body abrasive wear tester. The 3-Body wheel abrasion test was carried out at 950 rpm test speed. The tests were carried out at 30N load by varying the abrading distance from 100 to 200m and also under varyi…
The structure, the martensitic transformation and the magnetic properties of ferromagnetic shape memory alloy Mn2NiGa aged at low temperature are investigated. The lattice distortion and the internal stress are generated in the samples due to the fine precipitation generated during the aging treatment. When the precip…
Abstract Several homogenized models are compared for accurate representation of the AC magnetic properties of silicon steel sheets. Two of them are the generalized Pry and Bean models, which have a parameter for the frequency dependence of eddy‐current loss. The third model assumes a quadratic distribution of the magn…
The statistical mechanics of a linear noninteracting polymer chain with a large number of monomers is considered with fixed angular momentum. The radius of gyration for a linear polymer is derived exactly by functional integration. This result is then compared to simulations done with a large number of noninteracting…
As organic pigments are produced mainly in wet chemical processes, a novel gas to particle process for generating organic nanoscale pigments is introduced. This process is based on the expansion of a nearly saturated gas flow from an overpressure regime to ambient pressure conditions. The expansion is achieved in a La…
Polylactic acid has received much attention because of its biodegradable characteristics. However, to produce the polylactic acid, enormous energy is required at the current purification processes developed up to now. In this work, in order to reduce energy consumption, we proposed a novel purification method which co…
In this study, reflective properties have been systematically calculated for two-dimensional photonic crystal slabs in centered rectangular lattices with elliptical patterns for transverse electric polarization along perpendicular x- and y-directions. The slab structures can be geometrically optimized for a near-compl…
