Researchers present materials and device design/fabrication strategies for an array of highly stable and uniform SWCNT-based stretchable electronic devices consisting of capacitors, charge-trap floating-gate memory units, and logic gates (inverters and NAND/NOR gates). The researchers’ detailed material, electrical, and mechanical characterizations and theoretical analysis in mechanics provide useful insights in the design…

The most common method for making nanofibers employs electrospinning that uses an electrical charge to draw nanofibers from a polymeric solution. This technique utilizes large voltages and is strongly influenced by the dielectric properties of the material. It is also impossible to electrospin many biopolymers without blending with another polymer. Addressing these drawbacks, a team of researchers report a new method – magnetospinning…

Classical semiconductor physics suggests that a single charge transport CMOS device cannot achieve ultra-high-performance and ultra-low-standby-power at the same time. Nanoelectronics researchers are trying to design devices that hit the ‘sweet spot’, i.e. where a charge transport device can provide its highest performance at its lowest power consumption, especially in its ‘off’ state. In new work, researchers show a unique…

Presently, several techniques for detecting mRNAs are available,which include in situ hybridization and polymerase chain reaction. However, these single-point and end-point techniques require the killing of the cells and are thus unable to capture the expression of mRNA in real time and locality with high precision. In new work, scientists describe a new way of preparing functional DNA nanostructures that can provide accurate…

Counter intuitive to our idea of ‘perfection equals best performance’, researchers have shown that defects in nanocarbons could provide a breakthrough for increasing the quantum capacitance. By subjecting graphene layers to a reactive-ion etching process, the team has poked holes into graphene to create holey graphene, which can change the microscopic distribution of electrons and thereby increase the quantum capacitance of…
