    Bis(2-hydroxyethyl) amine Family Buffers

    The bis(2-hydroxyethyl)amine family buffers includes Bis-Tris, BES, and Bicine. Brief introduction of these three buffers are as follows. Bis-Tris Bis-tris is a zwitterionic buffering agent with pH range from 5.8 to 7.2. Bis-tris forms stable complex with Cu2+ and Pb2+ and a weak complex with many common metals, so formation constants should be taken into account when using this buffer in a soluti...

    Preparation of BCIP/NBT Color Development Solution

    BCIP/NBT is one of the substrate combinations for alkaline phosphatase (AP) and is used to detect antigen bound to nitrocellulose or other membranes. Under the catalysis of AP, BCIP is hydrolyzed to produce a strong reactive product that reacts with NBT to form an insoluble dark blue to bluish-purple product. The corresponding kit can be used for enzymatic chromogenic reaction of the alkaline phos...

    Synergetic Effect of LiBF4 and LiODFB as Wide-temperature Electrolytes in Li-ion Battery

    2018-03-06

    Currently, Li-ion battery has been widely used in 3C device, electric vehicles, with environmentally friendly, no memory effect and so on. However, the narrow application temperature range limits its application in some areas and fields. At present, commercial Li-ion battery electrolytes have application temperature range of -20 °C ~ 60 °C and show a significantly lower capacity outside these temp...

    Currently, LiPF6-containing electrolytes are widely used for Li-ion battery dute to good ion conductivity and reasonable safety. However, LiPF6 electrolytes are inevitably contaminated by a detrimental byproduct, hydrogen fluoride (HF), which causes fatal metal dissolution of cathode materials. Researchers have developed a variety of new lithium salts, such as LiBOB, LiODFB, LiFSI, to overcome LiP...
