Biofilms cause extensive damage to industrial settings. Thus, it is important to improve the existing techniques and develop new strategies to prevent bacterial biofilm formation. In the present study, we have prepared nanoporous polymer films from a self-assembled 1,2-polybutadiene-b-polydimethylsiloxane (1,2-PB-b-PDMS) block copolymer via chemical cross-linking of the 1,2-PB block followed ...

With the growing interest in foamed geopolymer manufacture, there is an increasing demand for tailoring these composites’ pore structure. The binary system of two surfactants offers a possibility enhancing foam formation efficiency and stability paste, however, their effects are not well understood. influence blends on formation, size, distribution fly ash-based matrix investigated synergistic ...

A selective eco-friendly micellar HPLC method was developed for investigation of moxifloxacin and related compounds in the presence its degradation products. Central composite design used to optimize experimental conditions. The proposed is based on isocratic elution a C18 column using 92.5% (v/v) biodegradable aqueous mobile phase containing 0.01 M sodium dihydrogen phosphate, 0.15 dodecyl sul...

template synthesis is a powerful method for the preparation of nanoscale materials with specific size and shape. cadmium oxide (cdo) nanoparticles were synthesized by using sodium dodecyl sulfate (sds), cd(oac)2.2h2o and sodium hydroxide as starting materials. the sample was characterized by x-ray diffraction (xrd), scanning electron microscopy (sem). the xrd pattern proves that the final produ...

Dynamic modification of poly(dimethylsiloxane) channels using a mixture of n-dodecyl-beta-D-maltoside (DDM) and sodium dodecyl sulfate (SDS) is able to suppress analyte adsorption and control electroosmotic flow (EOF). In this mixed surfactant system, the nonionic surfactant DDM functions as a surface blocking reagent, whereas the anionic surfactant SDS introduces negative charges to the channe...

The objective of our study was to compare the effects electron beam irradiation on development and reproduction Tetranychus urticae strains that were susceptible or resistant acequinocyl, bifenazate, etoxazole. Electron (50–400 Gy) applied T. eggs, nymphs, adults, after which hatching rate, emergence longevity, fecundity analyzed. Eggs all irradiated with 150 Gy, none them hatched. When protony...

Renin was purified from 47 kg of hog kidney to produce enough enzyme for enzymatic and physicochemical characterization. The procedure included extraction at pH 3.5 in the presence of protease inhibitors, two ammonium sulfate precipitations, ion exchange chromatography on Sepharose-hexamethylenediamino-pepstatin gel, gel filtration, and isoelectric focusing. Renin, 2.3 mg, with a specific activ...
