Mercury concentrations in tree rings may enable trees to be ‘witnesses’ of illegal gold mining activities in the Amazon
Mining often happens in artisanal and small-scale mining operations that burn gold-mercury amalgams to extract gold particles. Credit: Simon Topp. For hundreds of years, the Amazon has been exploited for its gold. Today, the precious metal is just as sought after, but the remaining tiny gold particles are much harder …
DNA scaffolds enable self-assembling 3D electronic devices
Chip-integrated 3D nanostructured device fabricated using DNA self-assembly (Left panel). A DNA crystal is grown at a designated substrate location (about 1000 crystals on 5μm pads are shown on a Right panel), then mineralized to silica and volumetrically templated with a semiconductor material before electrodes are attached (Center panel). The …
Photonic processor could enable ultrafast AI computations with extreme energy efficiency | MIT News
The deep neural network models that power today’s most demanding machine-learning applications have grown so large and complex that they are pushing the limits of traditional electronic computing hardware. Photonic hardware, which can perform machine-learning computations with light, offers a faster and more energy-efficient alternative. However, there are some types …
Nanoscale transistors could enable more efficient electronics | MIT News
Silicon transistors, which are used to amplify and switch signals, are a critical component in most electronic devices, from smartphones to automobiles. But silicon semiconductor technology is held back by a fundamental physical limit that prevents transistors from operating below a certain voltage. This limit, known as “Boltzmann tyranny,” hinders …
Stretchable transistors used in wearable devices enable in-sensor edge computing
Credit: Liu et al. Organic electrochemical transistors (OECTs) are neuromorphic transistors made of carbon-based materials that combine both electronic and ionic charge carriers. These transistors could be particularly effective solutions for amplifying and switching electronic signals in devices designed to be placed on the human skin, such as smart watches, …
Proton-conducting materials could enable new green energy technologies | MIT News
As the name suggests, most electronic devices today work through the movement of electrons. But materials that can efficiently conduct protons — the nucleus of the hydrogen atom — could be key to a number of important technologies for combating global climate change. Most proton-conducting inorganic materials available now require …
