Rolling circle amplification (RCA) generates single-stranded DNAs or RNA, and the diverse applications of this isothermal technique range from the sensitive detection of nucleic acids to analysis of single nucleotide polymorphisms. Microwave chemistry is widely applied to increase reaction rate as well as product yield and purity. The objectives of the present research were to apply microwave h...

We present the Ðrst model of resonant heating of coronal loops that incorporates the dependence of the loop density on the heating rate. By adopting the quasi-static equilibrium scaling law o P Q5@7, where o is the density and Q is the volumetric heating rate, we are able to approximate the well-known phenomena of chromospheric evaporation and chromospheric condensation, which regulate the coro...

Due to the high hardness and wear resistance, electroless nickel-boron (Ni-B) coatings have found numerous applications. In the present study, the influence of the heating rate on the morphological features of oxidized electroless Ni-B coatings was investigated. The oxidation behavior of electroless coating layers was studied with TGA method under non-isothermal conditions at heating rates 5, 9...

background: the homologous recombination (hr) is one of the conventional cloning methods for the production of recombinant dna. it is a quick method for in vivo dna cloning without using the high cost restriction enzymes. a few modifications in the cloning procedure can increase the efficiency of this method. m aterials and methods: in this study, effect of heating on the rate of the igg1 heavy...

Pyrolysis of high impact polystyrene (HIPS) waste has been investigated under different process parameters, such as temperature, heating rate and types of zeolitic catalysts to produce valuable liquid products. Liquid, gas and coke as products of pyrolysis and aromatic, naphthene, olefin and paraffin as liquid components were obtained and their molecular weight distributions were studied with c...

Cobalt ferrite (CoFe2 O4 ) nanoparticles have attracted significantly attentions for spintronics, recording media and bioapplications due to their unique magnetic and chemical properties. In this work, single phase CoFe2 O4 nanoparticles were synthesized at various coprecipitation temperatures (60, 80 and 90 °C) without post calcination. The effects of oleic acid as surfactant on the microstruc...

background and objectives: red colored fruits such as cornelian cherry (cornus mas l) are recognized as being healthy. the color of these fruits is an important sensory property in assessment of product quality therefore, minimizing the loss of color in the process is very important. materials and methods: in this study, comparison of the color, turbidity, degradation rate of anthocyanin, and r...

Dimerization process is essential for producing copolymers. The features of dimerization process like thermal-oxidative degradation should be well known to reach maximum efficiency and a superior reactor design. Also, the degradation mechanism of biodegradable polymers is important during sterilization processes. Thermal-oxidative degradation of PGA, PLLA, and their binary copolymers was invest...
