Element 32 in our International Year of the Periodic Table series is germanium. Found in some camera lenses and guitar effects pedals, it’s also present in some LCD TVs. Germanium oxide has a high index of refraction, meaning light travels through it particularly fast. This gives it applications in wide angle lenses for cameras and microscope …

As you might have picked up from previous pregnancy-related posts on the site (here and here), my wife and I have been expecting our first child. During labour and birth, terms like ‘epidural’, ‘gas and air’ and ‘induction of labour’ get thrown around, but what specific drugs do these involve? How do they work? What …
Element 31 in our International Year of the Periodic Table series is gallium. Gallium is a low melting point metal; combined with arsenic it is used in some types of solar cells, and it’s also a key component of the lasers that read from Blu-ray discs. Though it’s solid at room temperature, gallium’s melting point …
Recent experiments have shown that the elastic deformation behaviors of a polymeric material are consistent with the Cosserat elasticity under nonuniform deformation at a millimeter scale. Thus, an elastohydrodynamic lubrication model in the framework of the Cosserat continuum theory is proposed to explore the lubrication performance that deviates from the classical elastohydrodynamic lubrication theory for …
Cu-based brake pads applied in high-speed railway trains containing Ni-coated graphite flake and uncoated graphite flake were fabricated by powder metallurgy. The braking properties of the brake pads were investigated by a scaled down testing apparatus with the pad-on-disk configuration under various braking speeds and braking pressures. Compared with the brake pads containing uncoated graphite …
Element 29 in our International Year of the Periodic Table series is zinc. Commonly used to galvanise other metals, it’s found in cars and streetlights. Its compounds are used in sunscreens, cosmetics, and medicines. Galvanising is the process of coating iron and steel in a thin coating of zinc. This coating prevents oxidation by itself corroding …
Element 29 in our International Year of the Periodic Table series is copper. Though it might not have copper’s characteristic orange-red colour, the Statue of Liberty is made of this metal, and it’s also found in our everyday lives in the wiring and electronic devices in our homes. The Statue of Liberty is coated in …
The mystery concerning Matt Reeves’ The Batman film has had fans scratching their heads for months, particularly after Ben Affleck left the role. But it seems Warner Bros have made a massive steps in regards to who will don the cowl. According to Variety, Twilight‘s Robert Pattinson is in negotiations to play Batman in the spin-off …
Sheldon, Amy, Leonard, and Penny stay up to wait for a call from the Nobel Prize Committee to see if ShAmy won. Barry Kripke prank calls them (not cool) but Amy eventually gets the call. They won. Thinking they might be dreaming, Leonard finally gets to slap Sheldon awake. A lot of dreams are coming …
