Small angle neutron scattering is employed to estimate the interactions in complex multicomponent systems. The method is applied to describe a ternary system, poly(dimethyl siloxane) toluene with silica filler particles. Contrast variation by solvent deuteration is used to distinguish the three different partial structure factors of filled polymer samples, S(pp)(q), S(pf)(q), and S(ff)(q), wher...

The use of Karstedt's catalyst to study the reduction of Me2NCHO (DMF) by the popular "dual SiH"-containing tetramethyldisiloxane, HMe2SiOSiMe2H (1), has revealed that the first step in the process involves an initial single hydrosilylation to form HSiMe2OSiMe2OCH2NMe2 (3). This intermediate is readily isolated and purified via distillation. In the continued presence of the catalyst, 3 transfor...

This paper reports on the impact that corrosion of stainless steel current collectors has performance fade a symmetric, carbon/carbon electrochemical capacitor, operating with an aqueous electrolyte (1 M Na2SO4). The results obtained by applying ageing protocols (voltage–holding tests) confirm collector positive electrode undergoes tremendous degradation during 200 h in charged state. To preven...

Antimicrobial drug resistance among bacterial and fungal communities have been created a huge challenge for clinicians in treating infections. Conventional antibiotics get non-functional with time due to the rapid adaptation of microorganisms environment. Therefore, exploring alternative antimicrobial drugs/nanomaterials treat such infections is highly needed. an conventional antibiotics, funct...

Plasma co-polymers (co-p) were deposited with an atmospheric pressure plasma jet (APPJ) using a precursor mixture containing hexamethyldisiloxane (HMDSO) and limonene. A coating fragments from both precursors siloxane, carbonyl nitrogen functional groups was deposited. The flow rate of limonene found to be important parameter for co-polymerization tune the formation structure groups. FTIR XPS a...

Introduction: An accurate impression is essential to create a well-fitted dental prosthesis. This study aimed to compare the dimensional accuracy of three elastomeric materials using one-step and two-step impression techniques. Methods: In this study, 20 impressions were fabricated for each Vinyl siloxane ether (Identium), condensation silicone (Speedex), and a...

Poly(dimethyl siloxane) (PDMS) has been widely utilized in various fields of research. However, the weak mechanical properties PDMS have limited widespread application this material industry. Herein,...

Schallamach’s theory of rate-dependent bond dissociation is used to understand the fracture of a polymerglass interface. The model system consists of an elastomeric film (20 μm thick) of poly(dimethylsiloxane), chemically bonded to a silanized glass substrate. The fracture energy of the interface varies logarithmically with velocity, which is consistent with Schallamach’s theory of forced bond ...
