The ozone layer is a layer of gas in the Earth’s atmosphere that absorbs ultraviolet radiation from the Sun. 臭氧层是地球大气层中的一层气体,它能够吸收来自太阳的紫外线辐射。 The molecules that make up ozone gas are made of three bonded oxygen atoms. 臭氧分子是由三个氧原子结合而成的。 Ozo...
All lipids are made up of the same atoms: carbon (C), hydrogen (H) and oxygen (O). Lipids contain the same elements that make up carbohydrates but in different proportions. Lipids have a large proportion of carbon and hydrogen bonds and a small proportion of oxygen atoms. Although the st...
5.It is the atoms that make up iron, water, oxygen and the like. 正是原子构成了铁,水,氧气等物质。 6.Lung fever develops from flu. 流感引起肺炎 7.Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. 爱因斯坦通过数学运算提出相对论 8.The major...
This type of energy gets saved inside tiny atoms that remain invisible. These atoms make up the entire universe. The fission reaction that happens in nuclear plants forms enough energy to power up huge cities. 6. Solar Energy Consumption Solar energy consumption occurs from the movement of light...
Molecules, by definition, are composed of two or more atoms. They can consist of atoms of the same element or different elements. For instance, oxygen gas (O₂) is a molecule composed of two oxygen atoms bonded together, while water (H₂O) is a molecule made up of two hydrogen atom...
Shape Memory Materials (SSM) applications in oil and gas industry The SMAs can retain their permanent shape when its original shape is manipulated by heating/cooling cycles that enables the SME or superelasticity to be activated. This effect has been utilized in wide range of applications such as...
Writing with Atoms 01 July 2007 | Osman Cakmak | Issue 59 (July - September 2007) Sometimes we make the mistake of thinking that the art and wisdom of small things are easier to make than those which are big in size. Said Nursi rev… A Tale of Design and Love 01 July 2007 | ...
atoms and oxygen heteroatoms. The presence of hydrogen heteroatoms in the structure of these materials makes these polymers perform better than hydrocarbon polymers. PVEE (poly(vinyl ethyl ether)) is one of the most famous polymers that can increase the viscosity of carbon dioxide up to 14 times...

The most common ways to produce hydrogen gas are to use electricity to split water into hydrogen and oxygen (calledelectrolysis), to use steam to separate it from carbon atoms in natural gas, or through a process called coal gasification. The last two methods are how more than 90 percent of...
