Buyer’s Guide

Cleantech

A look at how nanotechnology benefits solar cells, water treatment, wind turbines and other clean energy applications

Technology update

Nanomagnetic effects find a cool application

(with audio) The observation of the magnetocaloric effect in readily fabricated thin films suggests nanostructures may be exploited in refrigeration.

Top-grade perovskite boosts solar cells

A hot-casting solution-processing technique produces perovskite crystals with millimetre size grain cells.

Protons penetrate graphene

Although theory suggests graphene is impermeable to protons, recent experiments show proton conductance of a single layer may be high.

Plasmons excite hot carriers

New theory could help enhance solar-energy conversion in photovoltaic devices and make better photocatalysts.

Lab talk

Tailoring nanowire diameter and density for improved light absorption

Accurately designing high efficiency photovoltaic devices without complicated fabrication steps.

An anisotropic self-powered directional sensor

Fabricating flexible nanogenerators with zinc oxide nanowires.

Highly active sea urchin-like catalysts

Constructing magnetic double-shelled Au catalysts with high stability and reusability.
