The long–term stability of proton conductors is one the most important factors in evaluating materials. Guest molecules can act as “bridges” for conduction channels and reside covalent organic frameworks, but they are prone to leakage. Therefore, it develop with intrinsic conductivity. In this paper, we synthesized an intrinsically sulfonated framework, TpPa–SO3H, which has a more stable conduc...

receiving full dose heparin (A kaolin clotting time; 56, 29, and 19 seconds) and four had been considered to have equivocal lupus inhibitor tests. On testing of subsequent samples from three of the equivocal patients, one with a A kaolin clotting time of 29 seconds was found to have a definite lupus inhibitor while the two others (19 and 14 seconds) were negative. The A kaolin clotting time in ...

Research was conducted in a certified organic apple (Malus x domestica Borkh.) orchard in 2000 to determine the effect of organic pest management techniques on pest control, apple yields and microbial populations on harvested apples. In Experiment I, apple colouring bags, sticky red spheres, kaolin particle film, kaolin particle film plus sticky red spheres, or colouring bags plus sticky red sp...

The needs for safe, therapeutically effective antidiarrheal combination continuously lead to effective treatment. When administered simultaneously, metronidazole-kaolin interactions have been reported by FDA but not studied. This paper is the first to study metronidazole-kaolin interactions. Adsorption isotherms of a metronidazole-kaolin antidiarrheal combination from aqueous solutions at an in...

Behavioral and electroantennogram responses of plum curculio, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), adults were tested for several methanolic plant extracts and organically approved insecticides. Plant extracts were evaluated for their potential as antifeedants or oviposition deterrents. These extract responses were also compared to those elicited by the non-neurotoxic, o...

Apoptosis was measured in rat alveolar macrophage NR8383 cells challenged in vitro with respirable quartz or kaolin dust and with the dusts pretreated with dipalmitoyl phosphatidylcholine (DPPC) to model conditioning of respired dusts by interaction with a primary phospholipid component of pulmonary surfactant. Quartz dust is known to induce apoptosis in vitro and in vivo. For this study, quart...

The paper reports a process for synthesis of γ-alumina from kaolin. Kaolin was transformed to meta-kaolin by calcination at 800 ̊C for 2h. γ-alumina powder was synthesized through extracting alumina from metakaolin via H2SO4 and meta-kaolin reactions and consequently precipitation in ethanol, which led to form the aluminum sulfate. The precipitated aluminum sulfate was dried and calcined at 900 ̊...

Both aprotinin and in vitro heparin and protamine dosing assays (RxDx System) have been shown to reduce postoperative bleeding in the cardiac surgery patient. While celite activated clotting time tests in the presence of heparin are artificially prolonged by aprotinin, the kaolin based ACT is not. In order to optimize heparin anticoagulation management during cardiac surgery when aprotinin is u...

Knoevenagel condensation between barbituric acid and aldehyde was investigated in the presence of sulfonic acid functionalized nanoporous silica (SBA-Pr-SO3H) and resulted in the formation of arylidene and bis-arylidene barbiturates. Excellent yields and short reaction times are related to the high efficiency of SBA-Pr-SO3H that the reactions take place easily in its nano-pores. SBA-Pr-SO3H as ...
