Reactant concentrations and pressures, temperature, and the presence of catalysts are some of those factors that can influence the rate of a reaction. However, the manner in which the rate of a reaction is expr
What are enzymes and how is the rate of enzyme reactions affected? And what are all the inhibitors and how they work? 1. What are enzymes? 2. What are their main properties? 3. Write an experiment to demonstrate the effect of temperature on enzyme reacti...
Though scientists warn that global warming will likely continue for centuries because of the long natural processes involved, there are a few things we can do to decrease the effects. Basically, they all boil down to this: Don't use as much of the stuff that creates greenhouse gases. On a...
Or you can buffer a retinol serum by mixing moisturizer with it in the palm of your hand before applying it directly to your skin since the moisturizer acts as a buffering agent to decrease the potency of the retinol. Post-Retinol Skin Care...
Such an advancement would dramatically decrease battery weight and could boast five to 10 times the energy of traditional lithium-ion batteries. While this technology still has a number of obstacles to overcome, it could one day revolutionize the electric car industry [source: Rahim]. Explaining ...
Bipolar plates are used to connect one fuel cell to another and are subjected to both oxidizing and reducing conditions and potentials. A big issue with bipolar plates is stability. Metallic bipolar plates can corrode, and the byproducts of corrosion (iron and chromium ions) can decrease the ...
regulate or accelerate the rate of absorption. Every concept of enhancing the bio-availability and selectivity of pharmaceuticals will be related with the fact that lower doses are used. Another solution is the “smart drug” concept, which aims to produce pharmaceuticals that go into a given ...
In the model hills, weathering advance rates diminish with time as the Darcy velocities decrease with depth. The system can thus attain a dynamical steady state at any erosion rate where the regolith thickness is constant in time and velocities of both fronts become equal to one another and to...
We reveal the formation of nanocrystalline Al oxide and highlight the solute partitioning between the oxide and the matrix and segregation to the internal interface. The sharp decrease in partitioning content of Mg in the peak-aged alloy emphasizes the impact of heat treatment on the oxide ...
Assessment Model v.2.183. In 2030, it is assumed to be 0.064 and 0.074 €/kWh in the 3.5° and 2 °C scenarios, respectively. In 2050, it is considered to decrease to 0.056 and 0.050 €/kWh in the 3.5° and 2 °C scenarios, respectively. Afterward, it is assumed to remain ...
