The potential of a dry powder co-formulant, kaolin, to improve the control of storage beetles by the entomopathogenic fungus Beauveria bassiana, isolate IMI389521, was investigated. The response of Oryzaephilus surinamensis adults to the fungus when applied to wheat at 1 × 10(10) conidia per kg with and without kaolin at 1.74 g per kg wheat was assessed. Addition of kaolin increased control fro...

Natural kaolinite obtained from Share, Nigeria was treated with ammonium carbonate to enhance the adsorption capacity. The optimum operating conditions for of metal ions on natural clay (SK clay) were employed carbonate-treated (SK-AC clay). data analysed using isotherm and kinetic models. statistical p-values less than 0.05, indicating that model terms are significant ions. pseudo-second-order...

Bleeding is a well described complication of percutaneous extracorporeal membrane oxygenation support (ECMO). In an effort to prevent ongoing percutaneous-cannula blood loss, we tried multiple methods to achieve hemostasis and obtained the best results with QuikClot Combat Gauze (Z-Medica Corp, Wallingford, CT). This product is made of kaolin, white alumina silicate clay, which initiates activa...

In this study the feasibility of preparing bioflocculant from excess biological sludge was investigated. Hydrochloric acid was used to disintegrate sludge to prepare bioflocculant. The effects of acid dosage and flocculating conditions were studied. The optimized disintegration conditions was that acid dosage was 10 mL for 50 mL sludge suspension. Factors such as bioflocculant dosage, pH and te...

Bacterial exopolysacchrides (EPSs) are produced by many bacteria. Nowadays there is an increasing interest in the isolation and exploitation of these polymers for industrial purposes. In general, biosynthesis of EPS varies from one strain to other strain and it depends on genes and enzymes involved in EPS production and secretion. In this study, EPS producing strains were isolated from municipa...

Core-shell microcapsules are typically made by preparing an emulsion and forming a polymer shell around the droplets. Conventionally, the emulsion is stabilised by surfactants or polymers. Alternatively, emulsions can be stabilised by fine particles; we discuss capsules made from ultrafine kaolin stabilised Pickering emulsions via interfacial polymerisation. This approach has a number of potent...

Voluntary running in an activity wheel establishes aversion to paired taste in rats. A proposed mechanism underlying this taste aversion learning is gastrointestinal discomfort caused by running. We tested this hypothesis by measuring the pica behavior (kaolin clay intake) of rats, because it is known that rats engage in pica behavior after various nausea-inducing treatments including irradiati...

Concerns about the management of glass wool waste, approximately 800,000 tons which are generated annually in Europe, increasing. To test feasibility incorporating this waste into ceramic materials, study examined reuse as a fluxing agent production clay- and waste-based building ceramics. Commercial kaolin clay two industrial residues, namely quartz-feldspar sand (QFS) copper slag (CS), were s...
