The research project demonstrated a power output of 20 watts using a fiber-optic laser and aims to increase this to kilowatts in the future.

The main goal of the WiPTherm project was to create an innovative wireless energy transfer system that could recharge energy storage components on micro and nano-sized satellites.

The IFIMUP was tasked with developing thermoelectric sensors capable of absorbing light at 1,550 nm and using them to charge energy storage devices.

Researchers have created a smart wound soldering paste called iSolder (intelligent solder).

Nanoparticle-based paste

In a conventional tissue soldering method, the application of heat causes the paste to polymerize, resulting in bonding with the underlying tissue. This efficiently closes the wound and promotes rapid healing.

The research, which was conducted on mice, demonstrates how these tiny nanomachines are propelled by urea present in urine and precisely target the tumor, attacking it with a radioisotope carried on their surface.

Bladder cancer has one of the highest incidence rates in the world and ranks as the fourth most common tumor in men. Despite its relatively low mortality rate, nearly half of bladder tumors resurface within 5 years, requiring ongoing patient monitoring. Frequent hospital visits and the need for repeat treatments contribute to making this type of cancer one of the most expensive to cure.

Putting “socks” on artificial muscles made from inexpensive materials helps them produce 40 times more flex than human muscle, a global research project has found, featuring researchers from the University of Wollongong (UOW) at the ARC Centre of Excellence for Electromaterials Science (ACES).

UOW researchers from ACES joined with international partners from the U.S., China and South Korea to develop sheath-run artificial muscles (SRAMs), that can be used to create intelligent materials and fabrics that react by sensing the environment around them.

It builds on the work over the past 15 years by researchers from UOW and their international colleagues who have invented several types of strong, powerful artificial muscles using materials ranging from high-tech carbon nanotubes (CNTs) to ordinary fishing line.

A recent study published in Nature Electronics discusses stretchable graphene–hydrogel interfaces for wearable and implantable bioelectronics.

Stretchable and conductive nanocomposites with mechanically soft, thin and biocompatible features play vital roles in developing wearable skin-like devices, smart soft robots and implantable bioelectronics.

Although several design strategies involving surface engineering have been reported to overcome the mechanical mismatch between the brittle electrodes and stretchable polymers, it is still challenging to realize monolithic integration of various components with diverse functionalities using the current ultrathin stretchable conductive nanocomposites. This is attributed to the lack of suitable conductive nanomaterial systems compatible with facile patterning strategies.

Scientists uncover new insights on polaritons, showing potential for breakthroughs in light manipulation and nanotechnology applications.

An international team of scientists provides an overview of the latest research on light-matter interactions. A team of scientists from the Fritz Haber Institute, the City University of New York, and the Universidad de Oviedo has published a comprehensive review article in the scientific journal Nature Reviews Materials. In this article, they provide an overview of the latest research on polaritons, tiny particles that arise when light and material interact in a special way.

Understanding Polaritons

Producing photons one at a time on demand at room temperature is a key requirement for the rollout of a quantum internet—and the practical quantum computers that would undergird that network. The photons can be used as quantum bits (qubits), the quantum equivalent of classical computing’s 0s and 1s. Labs around the world have devised various ways to generate single photons, but they can involve complex engineering techniques such as doped carbon nanotubes or costly cryogenically-cooled conditions. On the other hand, less complicated techniques such as using traditional light sources do not provide the necessary level of control over single-photon emissions required for quantum networks and computers.

Now, researchers from Tokyo University of Science (TUS) and the Okinawa Institute of Science and Technology have collaborated to develop a prototype room temperature single-photon light source using standard materials and methods. The team described the fabrication of the prototype and its results in a recent issue of the journal Physical Review Applied.

“Our single-photon light source … increases the potential to create quantum networks—a quantum internet—that are cost-effective and accessible.” —Kaoru Sanaka, Tokyo University of Science.

Background: The Promise of Prime Editing

Prime editing is a promising technology for changing genomic deoxyribonucleic acid (DNA) that has the potential to be used to cure genetic diseases in individuals. Prime editors are proteins that can replace a specific deoxyribonucleic acid sequence with another. PE systems necessitate three distinct nucleic acid hybridizations and are not dependent on double-strand deoxyribonucleic acid breaks or donor deoxyribonucleic acid templates.

Researchers must devise efficient and safe techniques to deliver prime editors in tissues in the in vivo settings to fulfill PE’s objective. While viral delivery techniques such as adenoviruses and adeno-associated viruses (AAVs) can transport PE in vivo, non-viral delivery techniques like lipid nanoparticles can sidestep these concerns by packaging PEs as temporarily expressing messenger ribonucleic acids.
