what about Molybdenum Powder

Molybdenum Powder is a rare and high melting point metal. Its density, low coefficient of thermal

expansion, high thermal conductivity, a certain hardness and good toughness. Products of high purity,

particle size specifications, and has good sintering properties and processing performance. This product

is widely used in iron and steel industry, metallurgy industry, aerospace fields, electronics, atomic

energy industry, light chemical industry, etc., the market prospect is very broad.
Molybdenum Powder is the production of molybdenum crucible, molybdenum head, round molybdenum rod,

molybdenum large slab of the main raw material products. While in alloy steel, low alloy steel,

stainless steel, tool steel, cast iron, cast just, non-ferrous alloys to add secondary materials,

molybdenum, make all kinds of alloy steel of strength, toughness, heat resistance, corrosion resistance,

weldability was to improve.
With the defense industry with continuous development of rare earth molybdenum smelting industry

products on the ever-widening application areas, the steel industry wide application of molybdenum

products, molybdenum powder and its products will lead to changes taking place. Molybdenum powder and

its products to improve performance of diverse changes of the alloy to wider applications, the use of

higher temperatures, greater corrosion resistance, needed special requirements of molybdenum powder

Chloroaurie acid save notes


Chloroaurie acid deliquescence, should be dry and protected from light.

Chloroaurie acid strong corrosive to metal, so the preparation of gold chloride acid solution should not
use metal spoon weighing HAuCl.
● for the preparation of colloidal gold should be double-distilled water distilled water distilled

water or three, or high quality deionized water.
● Preparation of colloidal gold is a glass container must be absolutely clean, use should be preceded

by the acid and rinse with distilled water. Is best handled by silicification, silicification method can

dichloro-5% chloroform solution of a silane soak a few minutes, rinse with distilled water and dried

after use.
● Identification and preservation of colloidal gold: Preparation of colloidal gold is not difficult,

but good quality colloidal gold system is not an easy task. Therefore, each system should be a good

colloidal gold test, mainly the indicators particle size, uniformity of size and whether the aggregation

of particles.

what is Tacrolimus

Tacrolimus is FK506, is extracted from a soil fungus macrolide antibiotic, has strong immunosuppressive
properties, is the strength of its drug cyclosporin A, 10-100 times, arise prevention of organ
transplant rejection is better than cyclosporine.
 Tacrolimus is only applied to the clinical history of more than ten years, the time is shorter.
Therefore, in some respects (Pharmacology and Toxicology) study is not comprehensive enough. The main
side effects of Tacrolimus nephrotoxicity, neurotoxicity, and circulatory system, digestive system,
respiratory system and cardiovascular system function. Tacrolimus can induce diabetes (odds of about 10%
to 30%), can cause severe ketoacidosis. Tacrolimus-related incidence of hypertension than CsA
significantly reduced. Tacrolimus and CsA with rapamycin compared with rapamycin is a calmodulin does
not interact with the new immunosuppressive agents, is considered to have no effect on blood pressure.
 Immunosuppressant macrolides (including FK506 and rapamycin, etc.) not only orally, but also for
external use, mainly for some skin diseases such as atopic dermatitis, psoriasis, lichen planus, contact
dermatitis and bald spots, etc. have a certain effect. In addition, "Arthritis and Rheumatism" magazine
(Arthritis Rheum 2003; 48:3328-3337) 12, says a report released last month, immunosuppressant tacrolimus
in 2 or 3mg / day dose of a single treatment of active rheumatoid arthritis (RA) appears safe and
effective, but usually larger doses greater improvements.

what is Hansenula

Hansenula of various shapes, round, oval, oval, sausage-shaped range. Multilateral budding. Some species
can form pseudohyphae.
Vegetative cells of the same shape and ascus. Ascospores 1, 4, cap shape, Saturn-shaped, round, semi-
circular, smooth surface.
Hansenula abnormal variant is a common species of the genus. Cells, round, diameter
4 ~ 7μm. There are sausage-shaped, for the 2.5 ~ 6 × 4.5 ~ 20μm. There are also long sausage-shaped
30μm were. Multilateral budding, can direct the formation of ascospores by the cells, each capsule has
1, 4 sub-spore ascus, but most of the two. Hat-shaped ascospores, often after being released by the
sub-capsule does not spread. The variant grown in wort flat colonies on agar slant, milky white, matt,
edge filamentous. Cultured in the wort after the wave surface with white fungus Pu, becomes turbid
medium, the bottom cell deposition. Can not ferment lactose and melibiose. For maltose and galactose, or
weak or non-fermented sour. Able to assimilate nitrate, are also strong oxidizing ability of
hydrocarbons, kerosene can be used as carbon source.
This is the yeast can produce more ethyl acetate, thereby increasing product flavor, can be used for
wine and food industry. However, they can use alcohol as carbon source, but also in the beverage dry
wrinkled surface bacteria Pu, so is alcohol production of harmful bacteria.
