Page 35: Research news on Functional materials

Functional materials are physical systems engineered so that their intrinsic properties—such as electrical conductivity, magnetization, optical response, ionic mobility, or mechanical deformation—can be deliberately modulated by external stimuli (e.g., electric or magnetic fields, light, temperature, stress, or chemical environment) to perform specific tasks. They encompass classes such as ferroelectrics, piezoelectrics, magnetoresistive and thermoelectric materials, shape-memory alloys, solid electrolytes, and stimuli-responsive polymers. In research and device design, functional materials serve as active components enabling sensing, actuation, energy conversion, information storage, and signal processing, with performance governed by their structure–property relationships across atomic, mesoscale, and macroscopic length scales.

Graphene dust is not harmful, study finds

Graphene-related materials (GRMs) are often used to reinforce polymers. In small concentrations of up to five weight percent, GRMs can significantly enhance the strength, electrical conductivity and thermal transport of composites ...

Promising new materials mimic muscle structure and function

Inspired by the structure of muscles, an innovative new strategy for creating fiber actuators could lead to advances in robotics, prosthetics, and smart clothing, according to a Penn State led team of scientists who discovered ...

New route to build materials out of tiny particles

Researcher Laura Rossi and her group at TU Delft have found a new way to build synthetic materials out of tiny glass particles—so-called colloids. Together with their colleagues from Queen's University and the University ...

Decoding the lifecycle of photogenerated charges

New materials will enable novel technologies to turn sunlight into electricity and fuels. Combinations of molecules and tiny nanoparticles make these materials a reality. The molecules in these materials are very good at ...

Real-time ultrafast humidity sensing optical sensor

The Hercules beetle native to South America has a fascinating trait of changing its shell colors depending on the external humidity conditions. This is because the inside of the beetle's shell consists of porous lattice structure ...
