• Physicists create world's smallest engine
  

  Theoretical physicists at Trinity College Dublin are among an international collaboration that has built the world's smallest engine - which, as a single calcium ion, is approximately ten billion times smaller than a car engine. Work performed by Professor John Goold's QuSys group in Trinity's Schoo more

• Examining puzzling sizes of extremely light calcium isotopes
  

  Michigan State University researchers have measured for the first time the nuclei of three proton-rich calcium isotopes. One of the most fundamental properties of the nucleus is its size. The nuclear radius generally increases with the number of proton and neutron constituents. However, when examine more

• Indented cement shows unique properties
  

  Rice University scientists have determined that no matter how large or small a piece of tobermorite is, it will respond to loading forces in precisely the same way. But poking it with a sharp point will change its strength. Tobermorite is a naturally occurring crystalline analog to the calcium-silic more

• Bearing grease selection

  Rolling-element bearings are used for the precise guidance of moving parts. Frictional losses are extremely small because the bearings rest on rolling elements, enabling very heavy loads to be adsorbed. Rolling-element bearings may be lubricated with more

Group 2 Elements

The second of a series of infographics on the groups of the periodic table, here some general properties of the group 2 elements are examined. As stated previously, these are primarily aimed at secondary school students, hence the relative simplicity and generality of the information presented. more

Testing for Cations

A previous post looked at the colours of transition metals, and the origin of their colours – this graphic, on the other hand, looks at how transition metals (and some non-transition metals) can be identified by the precipitates they form with sodium hydroxide and ammonia solutions. I’m going to kee more

The Dark Side of Fireworks

Many of us enjoyed watching spectacular fireworks displays to usher in the new year. However, the vibrant colours of fireworks belie the effects that they can have on the environment. With this graphic, we take a look at some of the issues that they can cause. more

• Mobility of Hydrous Species in Amorphous Calcium/Magnesium Carbonates

  Amorphous calcium carbonate (ACC) is commonly found in many biological materials. As ACC readily crystallizes into calcite, stabilizers, such as anions, cations or macromolecules often occur to avoid or delay unwanted crystallization. In biogenic ACC, magnesium is commonly present as one of the stab more

• Ultrafast neuronal imaging of dopamine dynamics with designed genetically encoded sensors

  Neuromodulatory systems exert profound influences on brain function. Understanding how these systems modify the operating mode of target circuits requires spatiotemporally precise measurement of neuromodulator release. We developed dLight1, an intensity-based genetically encoded dopamine indicator, more
