(Phys.org) —No two biological cells are exactly the same. Even a small biopsied tumor sample contains cells with large variations in their proliferation rate, potential for metastasis, drug responsiveness, etc. However, because ...
(Phys.org) —Today's commercial flash memories usually store data as electric charge in polysilicon layers. Because polysilicon is a single continuous material, defects in the material can interfere with the desired charge ...
(Phys.org) —If the recently released Google Glass and soon-to-be-available Apple iWatch are any indication, wearable electronics may be the next big wave of the future. Although they offer some cutting-edge features, from ...
(Phys.org) —As silicon-based electronics are predicted to reach their absolute limits on performance around 2020, new technologies have been proposed to continue the trend in the miniaturization of electronic devices. One ...
(Phys.org) —It may sound impossible that a 1-nm-thick piece of graphene—made of just a single layer of carbon atoms and containing some chlorine and fluorine atoms—can function as a two-stroke combustion engine. After all, ...
(Phys.org) —Carbon-based electronics are being widely explored due to their attractive electrical and mechanical properties, but synthesizing them in large quantities at low cost is still a challenge.
When imaging at the single-molecule level, small irregularities known as heterogeneities become apparent – features that are lost in higher-scale, so-called ensemble imaging. At the same time, it has until recently been challenging ...
(Phys.org) —Most of today's digital cameras achieve color by using red, green, and blue Bayer color filters through which light passes on its way to the camera's image sensors, which then convert the light into electrical ...
(Phys.org) —Carbon nanomaterials come in many different forms, such as diamond, aerogels, graphene, and soot. Sometimes carbon nanomaterials are even used as building blocks for making more complex nanomaterials. One recent ...
(Phys.org) —Miniaturized bioelectronic probes stand to transform biology and medicine by allowing measurement of intracellular components in vivo. Recently, scientists at Harvard University and Peking University designed, ...
