Art of paper-cutting inspires self-charging paper device

Despite the many advances in portable electronic devices, one thing remains constant: the need to plug them into a wall socket to recharge. Now researchers have developed a light-weight, paper-based device inspired by the Chinese and Japanese arts of paper-cutting that can harvest and store energy from body movements.

Triple treatment for heat-exchangers: New nano-coatings have an anti-adhesive, anti-corrosive and antimicrobial effect

When processing milk and juice, the food industry is using heat exchangers in numerous steps throughout the process. To have no risk to the consumers, heat exchangers have to be free from microbes. Especially in the numerous grooves and recesses of the heat exchanger, persistent biofilms can remain stuck. As a result, heat exchangers must be cleaned at regular intervals using aggressive chemicals. These increase the sensitivity for corrosion, especially if mild steel is used as heat exchanger material.

Fast capture of cancer markers will aid in diagnosis, treatment

A nanoscale product of human cells that was once considered junk is now known to play an important role in intercellular communication and in many disease processes, including cancer metastasis. Researchers have developed nanoprobes to rapidly isolate these rare markers, called extracellular vesicles (EVs), for potential development of precision cancer diagnoses and personalized anticancer treatments.

Major breakthrough in smart printed electronics

Researchers have fabricated printed transistors consisting entirely of 2-dimensional nanomaterials for the first time. This breakthrough could unlock the potential for applications such as food packaging that displays a digital countdown to warn you of spoiling, wine labels that alert you when your white wine is at its optimum temperature, or even a window pane that shows the day’s forecast.

Physicists develop ultrathin superconducting film

Experimental physicists have developed a thin nanomaterial with superconducting properties. Below about -200 °C these materials conduct electricity without loss, levitate magnets and can screen magnetic fields. The particularly interesting aspect of this work is that the research team has succeeded in creating superconducting nanowires that can be woven into an ultra-thin film that is as flexible as cling film.

Carbon nanotubes self-assemble into tiny transistors

Carbon nanotubes can be used to make very small electronic devices, but they are difficult to handle. Scientists have developed a method to select semiconducting nanotubes from a solution and make them self-assemble on a circuit of gold electrodes.
