The design and the use of highly active catalysts could diminish the amount of transition metal complexes, extend ATRP to less active monomers and give access to new chain〆nd functionalities. At the same time, very active catalysts can be involved in formation of organometallic species. Herein,...
Enzymes are considered catalysts as they speed up these chemical reactions without themselves being changed in the process. Enzymes feature an active...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ...
A sports cat manages to do everything a standard cat can do but in a much more sleek, efficient package. The honeycomb construction within a standard cat is designed to maximise the surface area of the catalysts while keeping their overall volumes low due to the sheer expense of the precious...
Why do catalysts not need to be replaced? How do rocks change in the rock cycle? How are physical and chemical weathering alike? Explain how alloying changes these pure metals to make alloys Why does aluminium not react with water?
打个比方就好比每天晚上你的电脑或者手机要进入维护模式,进行磁盘碎片整理(memory 的转移和索引),安装固件更新漏洞补丁(增强免疫系统功能)之类的,喝醉昏睡过去大概就等价于强行拔掉电源——虽然两种情况电脑都黑屏了,但是第二天重启的时候立刻就会知道区别很大。而熬夜晚睡则相当于长期运行内存效率低下、没有补丁的“裸奔...
Where do carrots come from? Another question to help us solve this mystery is looking at where carrots originate. The orange carrots we use on snowmen today were specially cultivated in the Netherlands in the 16thCentury. The myth and legend suggest that orange carrots were specifically bred by...
Why do we need solvents? In chemistry, solvents – which are generally in liquid form – are used to dissolve, suspend or extract other materials, usually without chemically changing either the solvents or the other materials. What is a good solvent? Water is capable of dissolving a variety ...

Regardless of the feeling that we’re at “peak screen” so to speak, Krishna’s hopeful that things will begin to even out — and he sees that a younger generation might be the catalysts behind it. “The young don’t admire swiping and tapping like their parents,” he says. “There...
elements. And it had not taken ‘big science’ to do it. But these discoveries do not in themselves appear to be enough. Like our man at the dinner party, many people are growing increasingly impatient to know what the fullerenes
