Scientists created the first practical bioresorbable 3D-printed airway stent

Various injuries and diseases cause the main bronchi or the trachea to narrow, which then makes breathing very difficult and people may suffer from the lack of oxygen. Surgical methods can bring quick relief, but metal or silicone stents usually require other surgeries. New study showed that 3D printable bioresorbable airway stents could be the answer in these situations.

These stents are 3D printed using a new light-activated resin. They disappear in the body in 6-7 weeks. Image credit: ETH Zurich

Metal airway stents have to be surgically removed, which is another invasive surgery, while silicone ones sometimes move away

New fiber optic temperature sensing approach to keep fusion power plants running

The pursuit of fusion as a safe, carbon-free, always-on energy source has intensified in recent years, with a number of organizations pursuing aggressive timelines for technology demonstrations and power plant designs. New-generation superconducting magnets are a critical enabler for many of these programs, which creates a growing need for sensors, controls, and other infrastructure that will allow the magnets to operate reliably in the harsh conditions of a commercial fusion power plant.

A collaborative group led by Department of Nuclear Science and Engineering (NSE) doctoral student Erica Salazar recently took a step forward in this area with a promising new

SDU researchers and Abena join forces to create face masks that neutralise and alert about corona

Nanoscientists from SDU and Abena, a production and trading company, want to create a face mask that not only neutralises the coronavirus but also alerts the user when the face mask comes in contact with the virus.

“We believe so much in the technology that we are embarking on the initial trials so that we can hopefully get the face mask on the market as soon as possible. A face mask that encapsulates and neutralises the corona, and at the same time alerts the user when your face mask is exposed to the virus.

3D-printed bioresorbable airway stent | Technology Org

Narrowing of the trachea or the main bronchi due to injury or illness can end very badly. If patients get too little oxygen, they risk suffocating and often need medical help as quickly as possible.

Surgeons insert stents made of medically usable silicone or metal as a way of treating these patients. Although they quickly bring relief, the implants also have disadvantages: Metal stents have to be removed surgically with some effort, which is a burden for the patients, while silicone stents often migrate away from the insertion site. The reason for this is that the implants are not adapted

New drone from SDU is ready to inspect powerlines

A team of researchers from the Maersk Mc-Kinney Moller Institute at the University of Southern Denmark has developed an intelligent drone with AI that can inspect high-voltage cables for faults and corrosion.

Denmark has over 7,000 kilometers of high-voltage cables. To ensure power in the sockets, the cables must be inspected regularly for faults and corrosion.

Today, the inspection task is performed by employees in lift trucks or helicopters, but that is expensive and involves risks due to the height.

Now, researchers from the Maersk Mc-Kinney Moller Institute at the University of Southern Denmark

An origami-inspired medical patch for sealing internal injuries

Many surgeries today are performed via minimally invasive procedures, in which a small incision is made and miniature cameras and surgical tools are threaded through the body to remove tumours and repair damaged tissues and organs. The process results in less pain and shorter recovery times compared to open surgery.

While many procedures can be performed in this way, surgeons can face challenges at an important step in the process: the sealing of internal wounds and tears.

MIT engineers have design paper-like medical tapes (shown here) that can fold around surgical tools and transform into soft, strong adhesives when pressed
