New bolometer is faster, simpler, and covers more wavelengths

Bolometers, devices that monitor electromagnetic radiation through heating of an absorbing material, are used by astronomers and homeowners alike. But most such devices have limited bandwidth and must be operated at ultralow ...

A new radiation detector made from graphene

Graphene is a remarkable material: light, strong, transparent and electrically conductive. It can also convert heat to electricity. Researchers have recently exploited this thermoelectric property to create a new kind of ...

Prototype developed to detect dark matter

A team of researchers from the University of Zaragoza (UNIZAR, Spain) and the Institut d'Astrophysique Spatiale (IAS, in France) has developed a "scintillating bolometer", a device that the scientists will use in efforts ...
