The donor and acceptor molecules self-assemble into a helical morphology under the effect of polar solvent. By controlling temperature to induce phase transition, co-crystal undergoes predictable crystal breaking or untwisting.

The existence of a structural transformation in Ni3AI alloys established earlier through X-ray diffraction, dilatometry and TEM investigations are summarised. The results obtained are discussed through a model proposed. The L12 structure appears to transform to another L12 or to a DOzz structure during heating. Such a transformation starts at around 700°C and seems to complete around 1100°C. In...

The extension of mathematical morphology to color and more generally to multivariate image data is still an open problem. The definition of multivariate morphological operators requires the introduction of a complete lattice structure on the image data, hence vectorial extrema computation methods are necessary. In this paper, we propose a lexicographical approach with this end, based on the pri...

Atomic processes, that governing the formation of crystalline surface morphology, attracted the considerable attention for possible applications in manufacturing of nanometer scale objects and providing accurate measurements in metrology and calibration techniques. In this paper some new results on the nanostructuring of the atomically clean silicon surface by means of in situ ultrahigh vacuum ...

This paper presents a framework for unsupervised natural language morphology induction wherein candidate suffixes are grouped into candidate inflection classes, which are then arranged in a lattice structure. With similar candidate inflection classes placed near one another in the lattice, I propose this structure is an ideal search space in which to isolate the true inflection classes of a lan...

Mathematical morphology is a nonlinear image processing methodology based on the application of complete lattice theory to spatial structures. Let us consider an image model where at each pixel is given a univariate Gaussian distribution. This model is interesting to represent for each pixel the measured mean intensity as well as the variance (or uncertainty) for such measurement. The aim of th...

Living organisms produce finely tuned biomineral architectures with the aid of biomineral-associated proteins. The functional amino acid residues in these proteins have been previously identified using in vitro and in silico experimentation in different biomineralization systems. However, the investigation in living organisms is limited owing to the difficulty in establishing appropriate geneti...

α‒Fe2O3/MoS2 nanocomposites were synthesized via hydrothermal method and characterized in terms of crystal structure, particle size and morphology, elemental purity and optical properties. Results confirmed the formation of α‒Fe2O3/MoS2 nanocomposites containing hematite nanoparticles with average diameter of 40 nm and MoS2 nanosheets with hexagonal crystal structure and sheet thickness o...

Manufactured single crystal components using Ni-base super alloys are routinely used in the hot sections of aero engines and industrial gas turbines due to their outstanding high temperature strength, toughness and resistance to degradation in corrosive and oxidative environments. To control the quality of the single crystal turbine blades, particular attention has been paid to grain selection,...

Pharmaceutical powder processing is notoriously subject to unpredictable jamming, sticking and charging disturbances. To unveil the material science underlying these effects, we use atomic force microscopy (AFM) on a common pharmaceutical, acetaminophen (APAP). Specifically, we study surface adhesion and morphology as a function of relative humidity (RH) for monoclinic acetaminophen, using both...
