Mitotic yeast cells express five septins (Cdc3, Cdc10, Cdc11, Cdc12, and Shs1/Sep7). Only Shs1 is nonessential. The four essential form a complex containing two copies of each, but their arrangement was not known. Single-particle analysis by EM confirmed that the heterooligomer octameric revealed subunits are arrayed in linear rod. Identity each subunit determined examining complexes lacking given septin, antibody decoration, fusion to marker proteins (GFP or maltose binding protein). rod...
This study used a multifunctional and versatile silicone rubber, which can be vulcanized at room temperature, as the stretchable elastomeric matrix. Then, reinforcing fillers such molybdenum disulfide (MoS2), diatomaceous earth (D.E.), hybrids were used. Our results showed that compressive modulus tensile strength are improved after addition of these fillers. For example, control sample was 1.93 MPa, it increased to 6.1 MPa 2.47 3.3 for their hybrid 20 phr. Similarly, 0.52 1.42 0.87 0.83 We...
Energy harvesting systems fabricated from rubber composite materials are promising due to their ability produce green energy with no environmental pollution. Thus, the present work investigated through piezoelectricity using composites. These composites were by mixing titanium carbide (TiC) and molybdenum disulfide (MoS2) as reinforcing electrically conductive fillers into a silicone matrix. Excellent mechanical electromechanical properties produced these For example, compressive modulus was...

The use of nanofillers with high surface area and extreme purity in polymer composite is an effective strategy to obtain performance polymeric nanocomposites. Therefore, the effect such as carbon nanotubes (CNT), titanium dioxide (TiO2), their hybrid on rubber-based composites was studied. In this study, rubber nanocomposites were fabricated by using room temperature vulcanized (RTV) silicone matrix (i.e. CNT, TiO2, CNT-TiO2) through solution casting method. Here, CNT (purity: >96% BET area:...
Zinc oxide performs as the best cure activator in sulfur-based vulcanization of rubber, but it is regarded a highly toxic material for aquatic organisms. Hence, should be replaced by non-toxic one. Still, there no suitable alternative industrially. However, binary activators combining ZnO and another metal such MgO can largely reduce level with some improved benefits rubber investigated this research. Curing, mechanical, thermal characteristics were to find out suitability rubber. Curing...
