Electrochemistry behind rechargeable lithium ion batteries

Batteries exist by the grace of people who want to be mobile at all times. Lithium ion batteries are especially popular because of their high energy density – up to 200 Watts of energy per kilogram of battery. But also because they can be recharged over and over again without deteriorating significantly. And that’s why […]

Data faster through glass fibre or copper?

You can download digital files from the internet via your glass fibre optic cable or through copper wire – coax cables, telephone cables (such as ADSL) or network cables (‘twisted pair’). One bit of information goes nearly as fast through copper as through glass, with two-thirds of the speed of light. This information is carried […]

Molecular dynamics computer simulations of yttria-stabilized zirconia

Computer simulations on an atomic or molecular scale give a direct link between the microscopic details of a system (atomic masses, molecular geometry, etc.) on the one hand, and macroscopic properties that are of experimental interest (energies, transport coefficients etc.) on the other. By comparing the outcome of the simulation with experimental results, understanding can […]

The hidden use of piezo technology in applications all around us

What is the common denominator in inkjet printers, parking sensors for cars, gas lighters and ultrasound imaging for babies? The answer: all these applications make use of piezoelectric materials. This material has something special: it has the capability to change shape – for example become shorter or wider – by applying an electric voltage over […]

iPolyCond – European knowledge transfer project

Between 1 October 2009 and 30 September 2011, Betase participated in the European knowledge transfer project iPolyCond, together with other European partners and partly funded by the European Commission. The booklet iPolyCond conductive polymers as well as the book An introduction to conductive polymer composites are results of the project, aiming at developing training materials […]
