Popeye would be proud According to physicists at Purdue University, spinach holds the promise of being able to convert sunlight into a clean, efficient alternative fuel. The Purdue team is part of an international group using spinach to study the proteins involved in photosynthesis, the process by which plants convert the sun’s energy into carbohydrates used to power cellular processes. ... » read more

Cool Magnets MIT researchers believe that magnets on the outside of the refrigerator may someday be used for cooling. Magnons, which are essentially a collective spin wave or quasi-particle, are also conductors of heat. MIT researchers found that when exposed to a magnetic field gradient, magnons can be driven from one end of a magnet to another, carrying heat with them. “You can p... » read more

Making flexible carbon nanotube circuits more reliable and efficient Engineers would love to create flexible electronic devices, such as e-readers that could be folded to fit into a pocket with one such approach involving designing circuits based on electronic fibers known as carbon nanotubes (CNTs) instead of rigid silicon chips -- but reliability is essential. Given that most silicon chip... » read more

Self-completing programs Since he was a graduate student, Armando Solar-Lezama, an associate professor in MIT’s Department of Electrical Engineering and Computer Science, has been working on a programming language called Sketch -- which allows programmers to simply omit some of the computational details of their code – and then automatically fills in the gaps. If it’s fleshed out and ... » read more

MoS2 FETs Two-dimensional materials are gaining steam in the R&D labs. The 2D materials include graphene, boron nitride (BN) and the transition-metal dichalcogenides (TMDs). One TMD, molybdenum diselenide (MoS2), is an attractive material for use in future field-effect transistors (FETs). MoS2 has several properties, including a non-zero band gap, atomic scale thickness and pristine int... » read more

Lasers From Nano Wires A few weeks ago, Semiconductor Engineering published a special report about silicon photonics and concentrated on the integration of the laser onto the silicon surface. Growing III-V materials on silicon is problematic because of the lattice mismatch, but researchers at the Technische Universität München (TUM) may have found a way around that problem. Thread-like semic... » read more
