This research is focused on developing trajectory planning tools for the automotive painting industry. The geometric complexity of automotive surfaces and the complexity of the spray patterns produced by modern paint atomizers combine to make this a challenging and interesting problem. This paper documents our efforts…
Abstract Amorphous calcium carbonate (ACC) was prepared in vitro by different methods. The preparation from carbon dioxide and aqueous calcium hydroxide gave a fully X‐ray amorphous phase without any additive. The precipitation from calcium chloride and sodium carbonate in the presence of either magnesium or ethylene‐…
A three-coordinate diketiminate-nickel(I) complex with a carbonyl ligand has been characterized using EPR and IR spectroscopies and X-ray crystallography. The T geometry (bending from the sterically favored C(2)(v)() structure) contrasts with that of isosteric d(9) copper(II) complexes. DFT calculations on a truncated…
This paper provides the theoretical basis for energetic vapor bubble implosions induced by a standing acoustic wave. Its primary goal is to describe, explain, and demonstrate the plausibility of the experimental observations by Taleyarkhan et al. [Science 295, 1868 (2002); Phys. Rev. E 69, 036109 (2004)] of thermonucl…
Abstract A magnetically-isolated one-dimensional chain can behave as if “magnet”— this sentence may be opposed to our common sense. In this review, we will show that a “magnet-like” behavior can effectively be found in only a magnetic spin chain. In 2001, which is almost forty years after the pioneering theoretical wo…
A series of crown ether type binaphthyl derivatives (CEBDs) were synthesized and used as chiral dopants to induce chiral nematic (N*) liquid crystals (LCs). The twisting powers of the CEBDs for phenylcyclohexane (PCH)-derived nematic LCs were evaluated. It was found that the twisting powers of the CEBDs increased with…
ABSTRACT The effects of chitosan (CH1 = 1% and CH2 = 2% solution), egg albumin (EA), soy protein concentrate (SPC), pink salmon protein powder (PSP), and arrowtooth flounder protein powder (AFP) as edible coatings on quality of skinless pink salmon fillets were evaluated during 3 mo frozen storage. Coating with 2% chi…
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…
