When emission of light occurs in the field of chemistry, it is undoubtedly related to a release in energy in form of light. For most elements or materials, the energy between energy levels or bonds is highly fixed. In this case, only a certain wavelength of light will be emitted under varying conditions.

Picture yourself using a paper-thin device which will continually keep track of your heart rate, respiration, or muscular activities without ever making you uncomfortable. You wouldn’t even realize its presence on your body. It is this kind of technology where the wearable health sensors necessitate the use of materials which are very light and flexible, as well as highly conductive.

Many by-sea tourist attractions advertise their seas to be fluorescent. Indeed, at night, the wavefronts show breath-taking glows of blue fluorescence.

When you dig deep into the mechanism of solar panels, you may find it to be photoemission effect. When light beam hits the substance, it transfers energy to all particles within. It is known to all that atoms are comprised of nucleons (protons and neutrons) and surrounding electrons. The nucleons are so tightly bonded that energy given by normal sunlight isn’t capable of overcoming the inter-particle forces. Electrons are different, they are much further away from nucleus and

Every day, we spend hours looking at the screens of smartphones, laptops, televisions, and tablets. Have you ever wondered how images appear on such small screens?

One of the most common elements in the earth is carbon. It is fundamental to life and is involved in various natural and chemical reactions. One unique characteristic of carbon is its ability to form four covalent bonds with other molecules which allow it to combine with other elements and form numerous complex and stable structures including carbon dioxide and biological molecules such as DNA. The element is found in various parts of the earth ranging from the atmosphere, wa

The Terminator series is always an unforgettable classic for all audiences. Since young, I am fascinated by this fictional universe created in Terminator 2: Judgment Day. However, what truly captures my attention is not just the storyline, but the most iconic figure—the liquid metal assassin. When the T-1000 melts through bars, reforms from scattered droplets, and reshapes itself into human form, it feels as if matter itself has escaped its physical boundaries.

For people all around the globe, no matter old or young, the Star Wars series is always an eternal classic. Since young, I’m obssess with this fictional universe created by the Lucas brothers. However, I am mostly into the most powerful weapon – lightsabers. When Luke ignited Anakin’s lightsaber and a beam of blue ejected from the hilt, I was thrilled.

During my tour in Japan, I noticed construction workers spraying concrete-like fluid on to the walls and within seconds the fluids “puffed up” and solidified, filling the gaps of the walls.

Carbon fiber is familiar to most people, because of its intense rigidity and solidity and lightness. In many parts of life, for example, prosthesis, car decorations, etc.

Water-proof takes a critical role in providing convenience in our daily life. From raincoats to digital device protection boxes, material’s water-proof characteristic protects the valuables and ourselves from erosions of water.

In the physics world, especially in the field of electromagnetics, most experiments suffer from the flaw of the existance of resistance within all apparatus. Many wonders if there is a way to eliminate such resistance. Here I would say, of course. This issue is directly addressed by the technology of superconductivity.

Have you experienced that fruits make your hands sticky? Many attribute to the sugar in the fruit juice that thickes as water evaporates.

It is common knowledge that a piece of feather is light enough that we can barely feel it when we hold it in our palm. But can you ever hold a block of air? How light will it be? The density of air is about 1.225. The mass of air in the volume of a hand-sized block is only about 0.0294g, almost negligible. Seemingly a fantasy, the solid blocks of gas do exist. Another name for them is “Aerogel”.

MOF is mostly known for its highly-porous structure. First found in 1995, Omar M. Yaghi used carboxylate-based linkers to demonstrate the crystallization of MOF. However, in this stage, MOF materials cannot maintain a stable porous structure. Thus, later in 1998, Omar introduced the concept of secondary building units, simplified as SBUs, which are metal-carboxylate clusters that are rigid enough to help MOFs retain porosity in any conditions. The first MOF that exhibits ultr
