A study was made of the effect of moisture on the emanation coefficient and radon flux from uranium mill tailings. A sharp rise in emanation coefficient occurred as the moisture content was increased from the absolutely dry state to 2% water by weight. The emanation coefficients from water-saturated tailings were abou…
A dynamical model is presented which describes the random motion of an interface of two coexisting phases. The Euclidean invariant stochastic equation of motion for the coordinate of the interface is derived systematically from the time-dependent Ginzburg-Landau model in the limit of infinitely deep potential well of…

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…
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…
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…
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…
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…

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…
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,…
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…

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…
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…
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…

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…
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.
