The control of crystal polymorphism of the trimorphic crystals of glycine (Gly) grown in aqueous solutions in the presence of α-amino acids operating as stereospecific nucleation inhibitors is reported. The presence of enantiopure α-amino acids phenylalanine (Phe), methionine (Met), and tryptophan (Trp) in the crystal…
The rheological behaviour of a cement paste used in Self-Compacting Concretes (SCC) formulations is compared to that of an “ordinary” cement paste (OC) devoid of organic admixtures. In order to mimic the flow conditions experienced by the cement paste in the inter granular space of concretes, the rheological behaviour…
The propagation of ultrasonic waves in polymers depends on their viscoelastic behaviour and density, resulting significantly affected by phase transitions occurring with changing temperature and pressure or during chemical reactions. Therefore, the application of low intensity ultrasound, acting as a high frequency dy…
Polymer melts can be mixed with many monomers, plasticizers, antistatics or foaming additives. Properties of such mixtures can change during blending because of chemical reactions like polymerization or crosslinking. The process may be carried out either in stirred tanks, extruders or in motionless mixers. In this pap…
Article Fundamentals of Interface and Colloid Science: Volume IV: Particulate Colloids and Volume V: Soft Colloids was published on October 1, 2005 in the journal Applied Rheology (volume 15, issue 5).
This paper reports the physical and mechanical properties of hand-woven carpets that have been put under static force. Two types of wool fibres, from two parts of Iran, were prepared to spin pile yarns for the carpets. Each group of fibres included both conventional and tanned wool. Next, two yarn counts, Nm = 4/2 and…
As a prototype of a pi-conjugated molecule bundled system, a series of B,B',B''-trianthryl- N,N',N''-triarylborazine derivatives bearing various p-substituted phenyl groups (p-R-C(6)H(4): R = hexyl (1), i-Pr (2), CF(3) (3), Br (5)) as aryl groups was designed and synthesized. The crystal structure analysis of these de…
The motion of rigid twisted ribbon-like particles in shear flow is studied by computer simulation. It is shown that the twisted ribbon migrates in the vorticity direction in strong shear flow with the sign determined by the chirality: the right-handed particles and their mirror-imaged particles move in opposite direct…
(Na 0.5 K 0.5 )NbO 3 (NKN) and BaTiO 3 (BT) ceramics form a homogeneous solid solution. The relative density of the (1- x )NKN– x BT solid solutions significantly decreased when x ≤0.07. Although the relative density of the 0.95NKN–0.05BT ceramic was very low, it had a high d 33 value of 134 pC/N. MnO 2 was added to i…
A simple closed-form expression for the dielectric nonlinearity in thin-film high-permittivity barium strontium titanate (BST) devices is obtained from a third-order power-series expansion for the field-polarization relation. The expression is parameterized in terms of easily measurable quantities of zero-field capaci…
Raman spectra were collected for crystalline albite from 25 °C to above the 1118 °C melting temperature, where vibrational assignments for the crystal spectra were determined by lattice dynamics (LD). The Raman spectra and associated vibrational assignments are reported for triclinic albite (NaAlSi 3 O 8 ) at 25 °C an…
What has been the contribution of surface potential studies during the last four decades to our understanding of insulation physics? Which are the promising techniques emerging in this field? The present review covers the industrial context accounting for the development of surface potential measurements on insulating…
Despite several advancements in chemotherapy, the real therapy of cancer still remains a challenge. The development of new anti-cancer drugs for the treatment of cancer has not kept pace with the progress in cancer therapy, because of the nonspecific drug distribution resulting in low tumour concentrations and systemi…
Nanocrystalline materials are polycrystals made up of nanometer-sized grains separated by a network of interfaces - grain or phase boundaries - that generally make a positive contribution to the total energy of the system. Consequently, there exists a thermodynamic driving force for reducing the overall interface area…
