Enzymes have a wide variety of applications in diverse biotechnological fields, and the immobilization of enzymes plays a key role in academic research or industrialization due to the stabilization and recyclability it confers. In this study, we immobilized the Brassica oleracea chlorophyllase 1 (BoCLH1) or Candida rugosa lipase (CRL) in magnetic iron oxide nanoparticles-loaded alginate composi...

Watt’s bath and pulse reverse (PR) electrodeposition is used to produce spherical nickelmultiwall carbon nanotubes (Ni-MWCNT) of 2.00, 0.93, 1.63 and 6.71 μm diameter and a variety ofsize distributions. For 60 cycles, an absolute electrodeposition current of 18 A/dm2 is applied atcurrent ratios of ii = idissolution/ideposition = 0, 0.077, 0.200 and 0.368. A simple exponential equation isfitted ...

A versatile patterning approach based on electron-beam lithography (eBL) and solution deposition, termed soft-eBL, has been developed to fabricate radially stacked heterostructures of multifunctional oxides from their sol precursors. Well-defined nanorings of lead zirconate titanate (PZT) are fabricated on a variety of substrates such as noble metals (e.g., Au), semiconductors (e.g., Si), and o...

Adhesive bonding technology is being used in a variety of modern industries, including the automotive, aerospace, maritime, construction, defense and so on. On the other side, polymeric nano - composites attracted both academic and industrial interests in the past decades. The scope of this paper is experimental investigation on the effects of the addition of Alpha-alumina nanoparticles to the ...

An elastomer is a polymer with the property of viscoelasticity, generally having notably low Young's modulus and high yield strain compared with other materials.  Elastomers, in particular rubbers, are used in a wide variety of products ranging from rubber hoses, isolation bearings, and shock absorbers to tires. Rubber has good properties and is thermal and electrical resistant. We used carbon ...

background and aims. the aim of the present study was to compare the efficacy of quartz tungsten halogen (qth) and light emitting diode (led) curing lights on polymerization of resin composite. materials and methods. a hybrid resin composite was used to prepare samples which were cured using two qth and ten led light curing sources. twelve groups, each containing ten samples, were prepared usin...

Similar to Agrobacterium tumerfaciens, Agrobacterium rhizogenes can transfer foreign DNAs into plant cells based on the autonomous root-inducing (Ri) plasmid. A. rhizogenes can cause hairy root formation on plant tissues and form composite plants after transformation. On these composite plants, some of the regenerated roots are transgenic, carrying the wild type T-DNA and the engineered binary ...

In this work, polymer composite materials based on linear low-density polyethylene armored with nanoparticles of aluminum oxide were obtained. A variety concentrations has been proven to affect the physical and mechanical properties resulting composite. Mechanical parameters studied in static dynamical regimes as well temperature dependence dynamic behavior samples was examined. As a result, op...
