Dissolving batteries Researchers at Iowa State University developed a self-destructing lithium-ion battery capable of delivering 2.5 volts and dissolving or dissipating in 30 minutes when dropped in water. The battery can power a desktop calculator for about 15 minutes. Making such devices possible is the goal of a relatively new field of study called "transient electronics." These transi... » read more

Safer drinking water Two-dimensional materials are gaining steam in the R&D labs. 2D materials include graphene, boron nitride (BN) and the transition-metal dichalcogenides (TMDs). These materials could one day enable future field-effect transistors (FETs). One TMD, molybdenum disulfide (MoS2), is also generating interest in other fields. Molybdenum disulfide consists of two elements--moly... » read more

Using trapped ions as quantum bits MIT researchers reminded that quantum computers are largely hypothetical devices that could perform some calculations much more rapidly than conventional computers can, and instead of the bits of classical computation — which can represent 0 or 1 — quantum computers consist of quantum bits, or qubits, which can, in some sense, represent 0 and 1 simultaneo... » read more

Faster FEBIDs Focused electron beam induced deposition (FEBID) is generating steam in the industry. Still in the R&D stage, FEBID makes use of an electron beam from a scanning electron microscope. Basically, it decomposes gaseous molecules, which, in turn, deposit materials and structures on a surface at the nanoscale. One of the big applications is a futuristic manufacturing technology... » read more

Phase-change memory Researchers at Stanford are working on phase-change memory technology, which could deliver the best of volatile and non-volatile memory. Phase-change materials can exist in two different atomic structures, each of which has a different electronic state. A crystalline, or ordered, atomic structure, permits the flow of electrons, while an amorphous, or disordered, struct... » read more

Helping drones navigate urban environments While it has been widely discussed, Amazon wants to start using drones to deliver packages by 2017, but if you live in a high-rise apartment, you might be waiting a bit longer because because UAVs (Unmanned Aerial Vehicles) use GPS for localization and navigation but in urban areas, high-rise buildings may block the line of sight to GPS satellites, ca... » read more

CMP replacement? For years, chipmakers have used chemical-mechanical-polishing (CMP) tools to smooth or polish the surface of a wafer. CMP works, but the technology is time-consuming and expensive. CMP can also leave unwanted residual patterns and defects near the surface. In response, Russia’s National Research Nuclear University MEPhI (Moscow Engineering Physics Institute) has help... » read more

From sun to hydrocarbon fuel Researchers at the University of Illinois at Chicago have engineered a solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy. Unlike conventional solar cells, which convert sunlight into electricity that must be stored in heavy batteries, the new device converts atmosph... » read more

Mixing topology, spin MIT researchers are studying new compounds, such as topological insulators (TIs), which support protected electron states on the surfaces of crystals that silicon-based technologies cannot as part of the pursuit of material platforms for the next generation of electronics. They report new physical phenomena being realized by combining this field of TIs with the subfiel... » read more

Jumping films Riken and the University of Tokyo have developed a tiny autonomous actuator. The actuator, which is based on a special material, can automatically curl up or straighten out when exposed to ambient humidity. And in certain conditions, the film can even jump into the air by itself. A video can be seen here. Researchers placed a material called guanidinium carbonate into a hig... » read more
