Electro-oxidation of CNT Joule heaters can be eliminated through the application of sufficiently high a.c. frequencies, which enables their use as self-heating membranes in membrane distillation.
The implementation of bio-inspired sparse coding algorithms aimed at image processing is demonstrated by exploiting 32 × 32 crossbar arrays of analogue memristors.
An optical non-linearity at the single-photon level is reported with a semiconductor quantum dot–cavity device. The device performs as an efficient single-photon filter that strongly suppresses the multiphoton components of incident coherent pulses.
Optical waveguides patterned with gradient metasurfaces have compact footprints and broad wavelengths of operation thanks to tight control of the scattered light.
The transitional link from robust clearance of intravenously injected nanoparticles by strategically placed macrophages in systemic circulation to adverse haemodynamic reactions can be overcome by changing nanoparticle geometry or by prior nanoparticle attachment to erythrocytes
The electron gas confined onto a charged head-to-head domain wall in the ultrathin ferroelectric tunnel layer of a multiferroic tunnel junction drives the overall transport processes through the whole device.
Graphene nanoconstrictions achieved via mechanical exfoliation of highly oriented pyrolytic graphite evidence clear signatures of one-dimensional transport via zigzag edges.
A DNA probe that translocates from one anchor site to another by toehold-mediated DNA strand displacement is used to monitor transient molecular encounter events on live cell membranes.
Nonmagnetic colloidal nanocrystals demonstrate magnetic properties due to spins of dangling bonds at their surface resulting in formation of dangling-bond magnetic polarons.
The high output voltage of triboelectric nanogenerators enables well-controlled ion pulses for nanoelectrospray molecular mass spectrometry and surface modification.
