Tumour Patch Uses Three Tools To Fight Cancer

Medgadget reports on the development by MIT researchers of an implanted cancer fighting patch that uses three elements to tackle tumours.

MIT researchers have created an implantable patch for the administration of three completely different therapies to tumor sites in order to kill and prevent the recurrence of cancer. The hydrogel patch is embedded with gold nanorods that are able to heat up and ablate nearby tissue when illuminated by infrared light. The same rods are also infused with a chemotherapy agent, which is also released when infrared light causes the temperature of the nanorods to rise. In addition to thermal and chemotherapy, the patch also releases RNA gene therapy that targets oncogenes active in the cancer being targeted.

Converting CO2 pollution into carbon for batteries

MIT Technology Review details a new approach to battery making that could utilise carbon dioxide from the air for conversion into carbon nanotubes to be used in high-performance battery production. The research – a collaboration between George Washington University and Vanderbilt University – could both reduce the costs of creating carbon nanotubes and play a part in battling climate change. From the article:

“Capturing and sequestering carbon dioxide is expensive and unproven at the scale needed to significantly reduce emissions. The deployment of carbon capture and storage (CCS) technology is well behind schedule if it is to play the role that the governments behind the recent Paris climate agreement are betting it can play. In the absence of climate policies like a cap-and-trade system or carbon tax, the economics just don’t work.”

“That might change if the gas could be turned into a valuable product. Researchers have previously devised methods for using carbon dioxide to make liquid fuels like methanol, but those products have been relatively low-value commodities. Given the cost of today’s batteries, the new method makes a kilogram of carbon dioxide six times more valuable than one that is converted into methanol, says Stuart Licht, a professor of chemistry at George Washington.”

“Replacing commonly used graphite anodes with carbon nanotubes can boost the storage capacity of advanced batteries. In proof-of-concept lab tests, Licht and his colleagues showed that nanotubes made with their process gave a small boost to the capacity of small lithium-ion batteries and almost quadrupled the capacity of sodium-ion batteries, an emerging energy storage technology.”

Nano Material Draws Water From The Air

FastCoExist reports on research at Harvard, where a nano-material is showing great promise in drawing water from the air. Inspired by a mix of natural features from desert beetles and cactus spines, the material could have industrial applications – e.g. speeding up condensation at thermal power plants – as well as harvesting water from the air in arid or rain-starved places.

Carbon nanotube film is stronger than kevlar and carbon fibre

Engadget reports that researchers in China have developed carbon nanotube film that  offers greater strength, flexibility and electrical conductivity than other carbon nanotube materials produced to date, as well as kevlar and carbon fibre, “making the new material ideal for use as a structural coating on vehicles and aerospace components or as next-generation electrodes.”
