Gram-Color Stain set for the Gram staining method-Merck
RM556.00Brand:
Merck
Description
Gram-Color – stain set for the Gram staining method, is used for human-medical cell diagnosis and serves the purpose of the bacteriological investigation of sample material of human origin, for example smears of body fluids. The Gram-Color solutions are modified and designed in such a way that staining can be carried out in staining cells, on the staining rack, and also in automated staining systems. Gram-color modified, phenol-free is a staining set for staining microorganisms. Aniline dyes in the cell tissue of microorganisms form a red dye-iodine complex when exposed to iodine. Sodium hydrogen carbonate enhances the formation of this complex further still. In gram-positive microorganisms the dye-iodine complex cannot be subsequently dissolved from the cells by decolorizing agents such as alcohol or acetone. The cell remains dark blue in color. In gram-negative microorganisms the dye-iodine complex is dissolved and the cell turns red as a result of counterstaining with fuchsin. Gram-color modified, phenol-free is an IVD / CE product.
The package is sufficient for 250 applications. For further information, please see the IFU which can be found in the kit.

Application
Because of the presence of oxygen-containing functional groups and acidic nature, GO can serve as both carbocatalyst as well as a supporting scaffold for various catalytically active species. GO can facilitate many organic transformations such as the oxidation of sulfides, olefins, and various hydrocarbons, Friedel–Crafts reaction, Aza–Michael additions, condensation, and ring-opening polymerization.
It can be used as a support for biocatalysis in organic solvents. For example, carboxyl-functionalized graphene oxide can act as a support to immobilize Yarrowia lipolytica lipase. The immobilized enzyme exhibits a high efficiency for the resolution of the racemic compound in the organic solvent.
It can also be used as a hole transport layer in organic photovoltaic cells.

General description
Handling of large quantities of GO powder is not recommended since graphene oxide powder is thermally unstable. Graphene oxide paste can make storage and transportation of large quantities in a safe manner. Graphene oxide solutions of desired concentration or graphene oxide paper or sheet can be made from graphene oxide paste. Sonication is required to obtain single layers of graphene oxide. To make a concentrated aqueous dispersion that will not settle under gravity: add 25 mL water/1 g paste, stir overnight for 16 h, sonicate for 30 minutes in a mild bath sonicator. Centrifuge (effective diameter of the rotor is 23 cm) at 3500 rpm for 10 minutes to remove any large unexfoliated particles and decant the supernate to give ∼2 mg/mL graphene oxide in water. The above concentrate can be diluted and sonicated further to get single layer graphene oxide.

Sigma-Aldrich
Synonyms

General Description
Hard carbon electrode sheet is an electrode film of activated carbon cast on copper. Hard carbon is a low-density material with extremely high microporosity. Standard electrode sheets are 5 inches x 10 inches (127 mm x 254 mm) and cast single-sided on 10 µm thick copper foil current collectors. The composition of the electrode film is 90% graphite, 5% poly(vinylidene fluoride) [PVDF] and 5% Super P. PVDF acts as binder due to its thermal and electrochemical stability and strong adhesive properties.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more information.
Application
Our hard carbon electrode sheet is a ready-to-use anode for alkali metal ion batteries such as sodium ion batteries (SIBs), lithium ion batteries (LIBs), and potassium ion batteries. Hard carbon is the anode of choice for sodium-ion batteries, where the use of graphite as an anode in SIBs is inhibited by the inability of sodium ions to form a binary graphite intercalation compound. Hard carbon offers a low insertion/deinsertion potential (~0.1 V Na/Na+) ideal for achieving high voltages. With an experimental capacity of 240 mAh/g and areal capacity of 2.32 mAh/cm2, our electrodes demonstrate outstanding electrochemical performance.
