题目I was sitting in a chemistry lab class during my first year of university,nervous about the experiment we were to perform.I grabbed a pipette (吸液管)and,as I feared,my hand started to shake.The experience was disheartening:I was hoping to pursue a career in scienc...
total energy/ virtual chemistry labsurface reactionsAb initio total-energy calculations based on electronic structure theory have tremendously enlarged our knowledge about the geometrical and electronic structure of clean and adsorbate-covered low-index surfaces and reactions on these surfaces. In ...
Ab initio total-energy calculations based on electronic structure theory have tremendously enlarged our knowledge about the geometrical and electronic structure of clean and adsorbate-covered low-index surfaces and reactions on these surfaces. In technological applications, however, extended flat surfaces are...

Rapamycin increases lifespan in mice, apparently by inhibiting a protein called mTOR. It may do the same in dogs and in humans. It's being tested in pet dogs.
Mitochondrial respiration17,18 or lipid oxidation19 could serve as sources, and centrosomes20 or chromo- phores in the mitochondria21 could serve as detectors. However, one crucial element for optical communication is not well established, namely the existence of physi- cal links to connect all of...
Primary production in the Southern Ocean (SO) is limited by iron availability. Hydrothermal vents have been identified as a potentially important source of iron to SO surface waters. Here we identify a recurring phytoplankton bloom in the high-nutrient,

There are different sources of heavy metals in the environment such as natural, agricultural, industrial, domestic effluent, and atmospheric sources, as well as other sources. They are stable in the environment, difficult to eliminate, and cause irreversible damage to the survival, feeding, growth,...
SNP genotyping was performed on a 7900 HT Real-Time PCR system using TaqMan (Life Technologies, Thermofisher Scientific, Bleiswijk, The Netherlands) chemistry under standard conditions. Primary SNP selection was obtained using a scientific literature search with the keywords: “GWAS, polymorphisms, ...
