Researchers address battery-life concerns with a new material system that can power a pulse oximeter with body heat alone. In the age of ever-present technology, dead batteries are a common hindrance. But for those relying on a wearable health care device to monitor glucose, reduce tremors or even track heart function, taking time to recharge can pose a big risk.

3D printing offers effective, scalable way to remove harmful chemicals Engineers have invented a new way to remove health-harming 'forever chemicals' from water - using 3D printing. Researchers at the University of Bath say their method, using ceramic-infused lattices (or 'monoliths'), removes at least 75% of perfluorooctanoic acid (PFOA), one of the most common perfluoroalkyl and polyfluoroalkyl substance (PFAS), from water, and could become an important tool in future efforts to eliminate the chemicals from water supplies.

New research on 3D-printed materials could unlock benefits for industry A new analysis of the deformation mechanisms which cause 3D-printed materials to fail under strain could help create future generations of stronger, lighter plastics, unlocking transformative benefits for industry.

Ultrathin material whose properties "already meet or exceed industry standards" enables superfast switching, extreme durability. In 2021, a team led by MIT physicists reported creating a new ultrathin ferroelectric material, or one where positive and negative charges separate into different layers. At the time they noted the material's potential for applications in computer memory and much more.

Developed at EPFL, Heriot-Watt University, and ETH Zurich, PrISMa is a new platform that uses advanced simulations and machine learning to streamline carbon capture technologies, by taking into account the perspectives of diverse stakeholders early in the research process. Mitigating the effects of climate change has become a major focus worldwide, with countries and international organizations developing various strategies to address the problem.

An MIT team uses computer models to measure atomic patterns in metals, essential for designing custom materials for use in aerospace, biomedicine, electronics, and more. The concept of short-range order (SRO) - the arrangement of atoms over small distances - in metallic alloys has been underexplored in materials science and engineering.

Taking advantage of the transformer neural networks that power large language models, engineers can get recipes for materials with the optical properties they need Study: OptoGPT: A foundation model for inverse design in optical multilayer thin film structures (DOI: 10.29026/oea. Solar cell, telescope and other optical component manufacturers may be able to design better devices more quickly with AI.

The approach could help engineers design more efficient energy-conversion systems and faster microelectronic devices, reducing waste heat. It is estimated that about 70 percent of the energy generated worldwide ends up as waste heat. If scientists could better predict how heat moves through semiconductors and insulators, they could design more efficient power generation systems.

Borrowing methods from biology, a team of scientists and engineers designed and tested an electrolyte that keeps battery power delivery high, cycle after cycle Study: Omics-enabled understanding of electric aircraft battery electrolytes (DOI: 10.1016/j.joule. A battery component innovation could help keep power delivery high when electric aircraft land with low charge, according to a study led by Lawrence Berkeley National Laboratory with expertise from the University of Michigan.

A US research team unveils this practice, which was intended to meet the demand in places where amber was scarce. A study by the QUANTAS research group of the University of Seville has revealed that prehistoric communities in Spain and Portugal developed the first known composite to simulate amber, reflecting the development of complex technical systems by these Neolithic artisans in regions where amber was scarce.

Innovative research approach enables the development of new materials and applications in technology and medicine. Researchers at Humboldt-Universität zu Berlin, led Nicola Pinna, have made a groundbreaking advancement in nanotechnology, successfully extending the well-known Stöber method to synthesize amorphous metal-organic frameworks (MOFs) and coordination polymers (CPs).

Investigations with participation by Heidelberg scientists show that later emerging small bodies brought water to the Earth Age data for certain classes of meteorite have made it possible to gain new findings on the origin of small water-rich astronomical bodies in the early solar system. These so-called planetesimals continually supplied building materials for planets - also for the Earth, whose original material contained little water.

Researchers from the University of Basel have looked at how the ferromagnetic properties of electrons in the two-dimensional semiconductor molybdenum disulfide can be better understood. They revealed a surprisingly simple way of measuring the energy needed to flip an electron spin. Ferromagnetism is an important physical phenomenon that plays a key role in many technologies.

In their recent paper , researchers from the University of Twente in the Netherlands have gained important insights into the elementary particles that make up light. These particles, photons , -behavein an amazingly greater variety than electrons surrounding atoms, while also being much easier to control.

A new electrolyte design for lithium metal batteries could significantly boost the range of electric vehicles. Researchers at ETH Zurich have radically reduced the amount of environmentally harmful fluorine required to stabilise these batteries. Lithium metal batteries are among the most promising candidates of the next generation of high-energy batteries.

A national bottle deposit fee could make a dramatic difference in reducing plastic waste, MIT researchers report. While recycling systems and bottle deposits have become increasingly widespread in the U.S., actual rates of recycling are "abysmal," according to a team of MIT researchers who studied the rates for recycling of PET, the plastic commonly used in beverage bottles.

The new design approach could be used to produce metals with exceptional combinations of strength and ductility, for aerospace and other applications. Titanium alloys are essential structural materials for a wide variety of applications, from aerospace and energy infrastructure to biomedical equipment.

Ruben Nicasy defended his PhD thesis at the Department of Applied Physics and Science Education on June 27th. Faster, greener and cheaper. These are currently the keywords within the printing industry, which is undergoing rapid innovations. TU/e researcher Ruben Nicasy developed an innovative method to determine how ink is absorbed by paper or cardboard in order to further improve print quality.

University of Wisconsin-Madison engineers have developed low-cost sensors that allow for real-time, continuous monitoring of nitrate in soil types that are common in Wisconsin. These printed electrochemical sensors could enable farmers to make better informed nutrient management decisions and reap economic benefits.

New findings could help engineers design materials for light and heat management. A butterfly's wing is covered in hundreds of thousands of tiny scales like miniature shingles on a paper-thin roof. A single scale is as small as a speck of dust yet surprisingly complex, with a corrugated surface of ridges that help to wick away water, manage heat, and reflect light to give a butterfly its signature shimmer.
