The protocols for in situ hybridization (ISH) techniques can vary considerably; however, they usually include denaturation and steps. Denaturing compounds are used to reduce temperature, which keeps the proper morphology of preparation. Formamide is most commonly reagent lower melting temperature. substitution toxic formamide a non-toxic ethylene carbonate at 20 % 50 concentration mixture helpe...

Abstract Two different nanosized mineral fillers (nano calcium carbonate and nanoclay) were used in the high density poly(ethylene) (HDPE) composites pilot plant production. Structural mechanical properties of prepared examined this study. The homogenous filler distribution was confirmed tested samples by scanning electron microscopy, transmission energy dispersive spectroscopy analyses. filler...

Electrolytes are involved in the thermal runaway (TR) process of cells, which is a potential hazard lithium-ion batteries (LIBs). Therefore, effects different mass ratio carbonate solvents (ethylene (EC)/propylene (PC)/ethyl methyl (EMC)) with LiBF4 and environmental pressure on combustion characteristics electrolyte such as flame centerline temperature, loss rate (MLR) heat release (HRR) were ...

Current performances of Li-, Na-, or K-ion batteries are mainly limited by the specific capacity positive electrode. Therefore, it is important to reach highest possible for a given electrode material. Here, we investigate performance limitation KVPO4F, prospective material batteries, which can deliver only 80% its theoretical capacity. We discover that KVPO4F related kinetic competition betwee...

We report on a room temperature (RT) sodium-sulfur (Na−S) battery based sodium anode, sulfurated poly(acrylonitrile) (SPAN) cathode and an electrolyte containing tetrakis(hexafluoroisopropyloxy) borate (Na[B(hfip)4]; hfip=hexafluoroisopropoxide) in mixture of ethylene carbonate (EC), dimethyl (DMC) fluoroethylene (FEC). The hfip anion as weakly coordinating (WCA) provides high anodic stability,...

The effect of different plasticizers on the properties of PAN– polymer electrolytes has been studied. Propylene carbonate (PC) and ethylene carbonate (EC) having different values of donor numbers, dielectric constant and viscosity have been used as plasticizers. The highest room temperature conductivity for the film in the PAN– system was 3.04 × 10-4 S cm-1. The highest room temperature conduct...

In this work, a method for capillary electrophoresis (CE) hyphenated to a high-resolution mass spectrometer was presented for monitoring the stability of anions in ionic liquids (ILs) and in commonly used lithium ion battery (LIB) electrolytes. The investigated ILs were 1-methyl-1-propylpyrrolidinium bis(trifluoromethanesulfonyl)imide (PYR13TFSI) and 1-methyl-1-propylpyrrolidinium bis(fluorosul...
