The measurements of linear expansion and remanent polarization have been performed for polycrystalline samples of Ba(Ti1−x ,Sn x )O3, (BTS-x. x = O, 0.05. 0.10, 0.20). The results obtained from the dilatometric investigations confirm the existence of the dipolar polarization Pd below 620 K, which has been previously o…
Abstract The uniformity of films and their surface roughness are of great importance in applications involving information recording (videotapes etc.). These properties of polymers processed with such film production techniques as tenter frame operations are not well understood. To understand the relationships between…

Abstract The thermal degradation of the first six members of poly(mono‐n‐alkyl itaconates) by thermogravimetry (TG), differential scanning calorimetry (DSC), Fourier Transform infrared (FTIR) and FTIR evolved gas analysis (FTIR‐EGA) was studied. The degradation mechanism involves cyclic anhydride formation followed by…
Anions can be adsorbed to soil colloids by specific (inner-sphere complexation) and nonspecific adsorption (outer-sphere complexation and diffuse ion association). The mechanism for anion adsorption determines whether and by what reaction anions in soil solution will enhance metal adsorption. The objectives of this st…
A review of plasma treatments of textiles is presented. The utility of plasma technology in processing textiles and the corresponding changes brought about in textile properties are discussed. The initiative, funded by the National Tex tile Center, and its progress to date is presented. This program features the use o…
Platelet concentrates (PCs), stored for 5 days in PL 2209, a new polyvinyl chloride (PVC) storage container plasticised with butyryl trihexyl citrate, were compared with those stored in PL 1240, a PVC platelet container plasticised with triethylhexyl trimellitate. In part 1 of the study, pooled platelet-rich plasma (P…
Analogy is one of the most powerful tools a physicist has to arrive at an understanding of the mysteries of nature. It allows us to make predictions about the properties of new systems from what we know about analogous well understood systems. One of the most striking analogies in physics is that introduced by de Genn…

A new method to investigate in-situ catalytic reactions on single-crystal surfaces is introduced. The real-time technique of measuring the adsorbate-induced surface stress has been applied to the oxidation reaction of CO on Pt (111). The adsorption of each of the reactants, CO and oxygen, on Pt (111) induces a compres…

Abstract Hydrothermal alteration has caused illitization along a 40m vertical profile in the Tsantilis bentonite deposit, Eastern Milos, Greece which consists principally of a Wyoming-type montmorillonite and authigenic K-feldspar. The product K-bentonite which contains illite/smectite, kaolinite, K-feldspar, quartz,…
Results presented in this paper demonstrate the roles of the most important parameters that govern abrasive wear of experimental ceramics. SEM studies of the abraded surfaces evidenced two main kinds of failures: microdropping of grain(s) and powder‐type wear track(s) resulting from the brittle microfracturing of part…

Microscopic structure and electronic states on the BaTiO 3 (100) single-crystal surfaces annealed in ultrahigh vacuum were observed by scanning tunneling microscopy and spectroscopy (STM/S). The surface step edges aligned preferentially along the [001] family of axes as the annealing temperature was increased. After a…

Enzymatic degradation, which improves surface properties by digesting protruding loose fibers, is gaining popularity because of its beneficial effects on the environment. In this study, two cotton / wool fabrics of different blend composition are treated with both cellulase and protease enzymes, applied at two differe…
Reports a survey of fabric handle preferences for a range of 50 men’s shirting materials. A total of 199 judges were divided into two panels according to their experience in the textile and clothing industry. Low levels of agreement were found which signify the errors inherent in subjective assessment of fabric handle…
ABSTRACT The blue‐green alga Anacystis nidulans Drouet (Synechococcus leopoliensis Raciborski) cultivated under phosphate‐limited conditions adopts a threshold value in the nanomolar range below which uptake ceases. In this study, we investigated the influence of phosphate pulses on the regulation of uptake behavior d…
