New display based on electrically induced index-matching in an inhomogeneous medium
The operation of a new light modulation device that employs electric field controlled light scattering in an inhomogeneous medium is described. The orientation of a nematic liquid crystal, contained in micrometer sized inclusions in a nonabsorbing solid, is changed to produce a varying refractive index. When the refra…
Patterns of Adsorption of Proteins From Human Plasma Onto Foreign Surfaces
The deposition of proteins on blood-contacting surfaces is known to be a determining factor in subsequent thromboembolic events. The composition of the protein layers and how they change with time are unknown. To generate information relevant to these questions, the quantities of albumin, fibrinogen and IgG adsorbed o…
Ferroelasticity and related properties of crystals
This article reviews at an introductory level the main concepts used in the description of ferroelasticity and other related properties of crystals, viz. ferrobielasticity, ferroelastoelectricity, ferromagnetoelasticity, ferrotrielasticity, and ferrogyrotropy. The symmetry and phase-transition aspects of these propert…
Invited review article ordering of voids and gas bubbles in radiation environments
Dr. Kanwar Krishan graduated from Panjab University, Chandigarh and did his doctorate from the Indian Institute of Technology, Kanpur in 1971. He was subsequently a Visiting Fellow at the Tata Institute of Fundamental Research, Bombay where his research interests were in magnetism and defects in solids. In 1972 he joi…
Mechanism of Crosslinking of Proteins by Glutaraldehyde II. Reaction with Monomeric and Polymeric Collagen
Collagen in three different states, i.e. native soluble molecules, denatured molecules and reconstituted fibers, was exposed to various concentrations of glutaraldehyde. The degree of intramolecular and intermolecular crosslink formation was evaluated by measuring collagen solubility, beta and gamma chain formation, r…

Preparation, analysis, and characterization of carbonated apatites.
A range of synthetic carbonated apatites were characterized using infrared and Raman spectroscopy, X-ray diffraction, and chemical analysis and compared to stoichiometric hydroxyapatite and dental enamel. Synthetic apatites were prepared by aqueous precipitation and by solid-state reaction at high temperatures. A meth…
PHASE BEHAVIOR IN SYSTEMS OF NONIONIC SURFACTANT/ WATER/ OIL AROUND THE HYDROPHILE-LIPOPHILE-BALANCE-TEMPERATURE (HLB-TEMPERATURE)
The phase diagram of the C12H25(OCH2CH2)5OH/water/tetradecane system was studied around the critical solution temperatures of surfactant-water and surfactant-oil phases. Although the phase behavior is very complicated due to the formation of liquid crystalline phase, basic phase-changes around the three-phase region,…
Radiation damage in crystalline insulators, oxides and ceramic nuclear fuels
Studies of radiation damage in crystalline insulators usually originate from problems connected with heavy ion impact during ion bombardment, from neutron irradiation with and without fission in nuclear reactors, or from α-decay with the resulting damage due to recoil daughter atoms of the decaying nuclei of actinide…

The Composition of the Surface During Passivation of Stainless Steels
Molybdenum alloyed austenitic stainless steels were exposed in 0.1 M HCl + 0.4M NaCl and polarized in the active and passive regions of the alloys. The treated surfaces were analyzed by utilization of the electron spectroscopy for chemical analysis (ESCA) method. The reaction products formed on the surface after passi…
Dislocations and the commensurate-incommensurate transition in two dimensions
The stability of weakly incommensurate two-dimensional solid phases described by periodic arrays of discommensurations has been investigated. It is shown that incommensurate phases consisting of a small number of possible commensurate domains of either the striped or honeycomb type are unstable with respect to the spo…
A thermodynamic criterion of the crystalline-to-amorphous transition in silicon
It is shown that the crystal lattice expansion of microcrystalline silicon leads, in the limit of small crystallite size of about 30 Å, to an instability of the diamond structure with respect to the amorphous phase. Simple thermodynamic considerations are presented which support the idea of the crystalline-to-amorphou…

Burst Criterion of Zircaloy Fuel Claddings in a Loss-of-Coolant Accident
A burst criterion model has been developed to calculate the burst data of Zircaloy claddings of a pressurized water reactor in a loss-of-coolant accident. It is assumed by this model that the time of burst is reached when the local stress equals the limiting burst stress. The burst stress is assumed to depend on the t…
Electrochemical doping of poly-(p-phenylene) with application to organic batteries
The first examples of electrochemical doping of poly-(p-phenylene) to form n- and p-type complexes with counter ions such as Li+ and AsF6– are reported; polyphenylene can be used as the electroactive material in rechargeable battery electrodes.
[Use of immobilization for the study of glyceraldehyde 3-phosphate dehydrogenase. Immobilized dimers of the enzyme].
The immobilized dimers of glyceraldehyde 3-phosphate dehydrogenase have been obtained after dissociation of the tetrameric enzyme molecule linked by one of the subunits with Sepharose 4B. The catalytic parameters (V, Km and pH-dependence of activity) of the immobilized dimers and tetramers of the enzyme are identical.…
Heat treatment of complex aluminium bronzes
Constitution, microstructure, cooling–transformation (CT) diagrams, and corresponding diagrams for mechanical properties are summarized for the Cu–Al–X alloy types (X = Fe, Ni, Mn, Be, Co, Si, and Sn) with β-transformation. On the basis of the cooling time, it is possible to simulate the micro-structure and the proper…
