Properties and applications and SBA-3, MCM-41 molecular sieve mesoporous relative toother, SBA-15 mesoporous molecular sieve with a larger diameter, thicker walls of the pores and the volume of the upper pores, but also better thermal stability of water is nature, is conducive to high temperature the reaction system, water consumption, so as catalysis, separation, and other areas of biology and nanomaterials have broad prospects applications. May redox, pH, polymerization reactions, the photocatalytic reaction, esterification, Fischer-Tropsch synthesis, a chiral synthesis catalyst for the adsorptive separation and immobilization of enzymes and the nanowires matrix synthesis and other nano-functional materials used, can be used.

Instructions sealed.
This product is not toxic, but improper use can cause respiratory, eye slight stimulation, direct contact may cause dry skin. Recommended to wear masks and gloves when using.

Crowdfunding develop new alcohol tester

Located in New York recently Verisense company plans to raise funds for the development of new alcohol detectors on the crowdfunding platform Indiegogo. By integrating apple company HealthKit, researchers hope that this detector can also be displayed automatically in the fast amount of the driver's blood alcohol concentration at the same time and so recently sidewalk, parking and restaurant information for the driver to rest. Staff Vertisense hope that through technological advances to further reduce the risk of drunk driving.

In fact, as early as 2013, the company has launched an earlier version Alcohoot of this equipment. Alcohoot can help law enforcement to quickly determine blood alcohol concentration of the driver and share data quickly. The company is working with police Missouri, Arkansas and Ohio, the new equipment first study. In addition, the new Alcohoot Edge also incorporates HealthKit, users can recommend an appropriate alcohol consumption through a special algorithm, can be described as caring.

In recent years, the US government attaches great importance to the dangers of drunk driving and control. Although effective in terms of control drunk driving, but the data shows the ages of 20-30 years of age, there are still a quarter of young Americans had been drinking and driving experience. These are likely to be hidden "killers." Researchers also hope to incorporate new technologies and sound regulations can create a safer traffic environment.

Description:
Bee venom is a complex composition of enzymes, proteins and amino acids. It is a clear, colorless liquid with a sweet taste and slightly bitter. It is soluble in water, insoluble in alcohol and ammonium sulfate.

Metoprolol Succinate


The form of the succinic acid salt of metoprolol, a cardio beta-1 adrenergic receptor competition with hypotensive properties and has no intrinsic sympathomimetic. Metoprolol succinate upset beta-1-adrenergic receptors in the myocardium, thus reducing the rate and the heart muscle contraction force is reduced, and thus a reduction in cardiac output. This composition may also renin secretion, with subsequent reduction of the levels of angiotensin II, thus reducing sympathetic activation decreases, including vasoconstriction, aldosterone secretion.
