A microscopic ‘pen’ that is able to write structures small enough to trap and harness light using a commercially available printing technique could be used for sensing, biotechnology, lasers, and studying the interaction between light and matter.
A smart material that switches back and forth between transparent and opaque could be installed in buildings or automobiles, potentially reducing energy bills by avoiding the need for costly air conditioning.
Researchers have built a nano-engine that could form the basis for future applications in nano-robotics, including robots small enough to enter living cells.
Researchers from the University of Cambridge have designed a new type of pixel element and demonstrated its unique switching capability, which could make three-dimensional holographic displays possible.
Intensely coloured low-cost films made from cellulose could be used in place of toxic dyes, or to detect counterfeit materials.
A breakthrough in the use of carbon nanotubes as optical projectors has enabled scientists to generate holograms using the smallest ever pixels.
