Dec 25, 2024 (Nanowerk News) A cutting-edge study has propelled the development of covalent organic frameworks (COFs), particularly imine-linked varieties, into the spotlight. Known for their tunable structure and remarkable stability, imine-linked COFs are set to revolutionize industries ranging from gas capture to advanced electronics. By focusing on the design...

Dec 25, 2024 (Nanowerk News) A research team at POSTECH has developed a breakthrough technology that analyzes in real-time the deformation of ‘serpentine’ structures, a critical component of stretchable technology and visualizes the process through color changes. The team, led by Professor Su Seok Choi from the Department of Electrical...

Dec 24, 2024 (Nanowerk Spotlight) Circuit boards form the foundation of modern electronics, but their production relies on materials that persist in the environment for centuries. These boards must meet precise technical requirements: perfectly smooth surfaces for mounting components, specific electrical properties to carry signals without interference, and the ability...

Dec 23, 2024 (Nanowerk News) Quantum sensing is a rapidly developing field that utilizes the quantum states of particles, such as superposition, entanglement, and spin states, to detect changes in physical, chemical, or biological systems. A promising type of quantum nanosensor is nanodiamonds (NDs) equipped with nitrogen-vacancy (NV) centers. These...

Dec 23, 2024 (Nanowerk Spotlight) Metal halide perovskites have attracted substantial research interest since 2009 when their potential for solar cell applications was first demonstrated. These semiconductor materials combine effective light absorption with good electrical conductivity while being simple to manufacture. However, metal halide perovskites degrade rapidly under normal environmental...

Dec 23, 2024 (Nanowerk News) DGIST announced that a team led by Prof. Jang Kyung-In from the Department of Robotics and Mechatronics Engineering has developed a three-dimensional stretchable piezoelectric energy harvester that can harvest electrical energy using body movements. The device is to be used as a wearable energy harvester...

Dec 21, 2024 (Nanowerk News) Researchers at Rice University have made a meaningful advance in the simulation of molecular electron transfer — a fundamental process underpinning countless physical, chemical and biological processes. The study, published in Science Advances ("Trapped-ion quantum simulation of electron transfer models with tunable dissipation"), details the...

Dec 21, 2024 (Nanowerk News) One of the biggest mysteries in science – dark energy – doesn't actually exist, according to researchers looking to solve the riddle of how the Universe is expanding. For the past 100 years, physicists have generally assumed that the cosmos is growing equally in all...

Dec 21, 2024 (Nanowerk News) Monitoring electrical signals in biological systems helps scientists understand how cells communicate, which can aid in the diagnosis and treatment of conditions like arrhythmia and Alzheimer’s. But devices that record electrical signals in cell cultures and other liquid environments often use wires to connect each...

Dec 20, 2024 (Nanowerk Spotlight) A black cotton T-shirt absorbs about 85% of visible light. The darkest paints can capture about 95%. But researchers have now created materials so black they absorb 99.7% of all light that hits them - making them appear as almost perfect voids to human eyes....
