hazelnuts are usually propagated by suckers or layering. however, other methods of propagation have been tested with variable results. grafting is a method that has a few advantages such as fast multiplication rate, earlier fruiting and reducing sucker removal cost on specific rootstocks. unfortunately, grafting is difficult due to slow formation of callus in hazelnuts. here, we report the hypo...

Hydrated salts (salt hydrates) are highly promising low-temperature phase change materials (PCMs) due to their high cohesive energy density and low cost. However, they exhibit separation, liquid leakage, inherent supercooling, which hinder applications in sustainable building technology. Here, we describe the design of a stable emulsion gel system (EmulGels) that exhibits nonflammable shape-mem...

the separation of olefin/paraffin mixtures is an important process in petrochemical industries, which is traditionally performed by low temperature distillation with a high-energy consumption, or complex extractive distillationand adsorption techniques. membrane separation process is emerging as an alternative for traditional separation processes with respect to low energy and simple operation....

Superior encapsulation technology is important for PSCs to prolong their lifetime and realize commercial application. Paraffin/EVA/paraffin composite encapsulated layers were fabricated with the ambient environment under thermal temperature of 80°C, which has advantages simple procedures low cost. paraffin/EVA/paraffin pure EVA maintained 95 45% initial power conversion efficiency (PCE) aged 10...

Thermal energy storage systems that use composite phase change materials (CPCM), such as paraffin wax and nonbiodegradable high-density polyethylene, are gaining attention in recent years due to the effort resolve issues. There is a need undertake research development on how prepare durable CPCMs from thermo-chemically treated biowastes, renewable resource. Raw spent coffee grounds (SCG) have b...

introduction: the provision of an effective apical seal is an essential factor when choosing an appropriate material for success of root-end surgeries. root-end resection, preparation and obturation should provide an adequate apical seal. the aim of this in vitro study was to investigate bacterial and dye microleakage of four different root-end filling materials and compare the efficacy of thes...

The article is devoted to the study of influence asphalt-resin-paraffin deposits on temperature oil saturation by paraffin. As a result analysis and generalization published works statistical information, empirical dependences paraffin content asphaltenes, resins paraffin, were obtained, which identified for conditions Ural-Volga region Kazakhstan
