The chemical term alkanes, or paraffins, refers to organic compounds that consist of single-bonded carbon and hydrogen atoms, such as methane, ethane, and propane, and several other hydrocarbons. Over the years, alkanes have ...
(Phys.org)—It may sound counterintuitive that replacing one of the most photosensitive solar cell materials with a material with less desirable photosensitive properties can improve the solar cell's efficiency, but that's ...
(PhysOrg.com) -- Titania semiconducting nanorods grown on the surface of carbon fibers look more like bristles on a tiny hairbrush than a solar cell, but the novel configuration could have several advantages over conventional ...
(PhysOrg.com) -- There are many ways to generate hydrogen, such as water electrolysis and steam reforming of gas, but the hydrogen produced by these methods tends to be combined with other byproduct and residual gases. For ...
(PhysOrg.com) -- Researchers have found a new use for graphene, the single-atom-thick sheet of carbon atoms that resembles chicken wire. Ever since graphene was first observed in 2004, its large surface area, excellent mechanical ...
(PhysOrg.com) -- Porphyrins are most commonly thought of as the pigment in red blood cells, but now scientists have found that porphyrins can also be used to increase the efficiency of an inexpensive type of solar cell. In ...
(PhysOrg.com) -- Researchers at The Pennsylvania State University have determined a way to use arrays of nanotubes in a solar-based process to convert carbon dioxide and water into methane and other hydrocarbon fuels. Their ...
The hydrocarbon methane is highly abundant on Earth, yet its release is now known to contribute to surges in temperature and climate change. In recent years, researchers have been trying to devise reliable methods to directly ...
Glitter is the bane of every parent and primary school teacher. But beyond its general annoyance factor, it's also made of toxic and unsustainable materials, and contributes to plastic pollution.

Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO2. When used as a pigment, it is called titanium white, Pigment White 6, or CI 77891. It is noteworthy for its wide range of applications, from paint to sunscreen to food colouring, for which it was given E number E171.
