Oxidative redispersion at elevated temperatures has long been utilized in heterogeneous catalysis for the regeneration of sintered metal catalysts and the synthesis of metal single atom and cluster catalysts. These redispersion processes require a considerable energy input. Therefore, the quest for eco-friendly and energy-saving redispersion strategies remains an urgent priority.

In order to better understand fundamental processes in life science at the molecular level, the precise observation of single molecule dynamics is of utmost interest. However, current techniques based on fluorescence measurements in aqueous solutions are unable to track changes in molecular structure with sufficient temporal resolution.

By exploiting a smart learning algorithm that fuses two microscopy signals, University of Michigan researchers have accomplished high-resolution, efficient 3D chemical imaging for the first time at the one-nanometer scale. For context, a nanometer is one-millionth of a millimeter, or one-hundred-thousandth the width of a human hair.

In a new discovery, researchers have revealed novel insights into the behavior of water molecules confined within nanostructures. Their study, published in Science Advances on April 24, delves into how terahertz (THz) waves influence the dynamics of water molecules confined in two-dimensional (2D) spaces within nanoresonators.

Traditional semiconductors such as Si, GaAs, and HgCdTe seem unable to meet the development trend of electronic devices that feature ultra-small volume, lightweight, and low power consumption. These limitations of traditional semiconductors mainly stem from complex growth conditions and low-temperature working environments.

Inexpensive and readily available copper-based catalysts are considered ideal for the electrochemical CO2 reduction reaction (CO2RR) to produce multi-carbon products. The presence of copper oxides is crucial for generating high-value-added products in CO2RR.

Engineered protein filaments originally produced by bacteria have been modified by scientists to conduct electricity. In a study published recently in the journal Small, researchers revealed that protein nanowires—which were modified by adding a single compound—can conduct electricity over short distances and harness energy from moisture in the air.

A team of researchers led by Nanyang Technological University, Singapore (NTU Singapore) has created tiny droplets that, when activated by laser light, can detect viral protein biomarkers indicating the presence of certain diseases.

A research team led by the late Professor Liang Haojun from the Hefei National Laboratory for Physical Sciences at the Microscale of University of Science and Technology of China (USTC) has developed a facile enthalpy-mediated strategy to precisely control the replication and catalytic assembly of DNA-functionalized colloids in a time-dependent manner, facilitating the creation of large-scale ordered nanomaterials. The study was published in Angewandte Chemie International Edition.

A collaborative research team from NIMS and Tokyo University of Science has successfully developed an artificial intelligence (AI) device that executes brain-like information processing through few-molecule reservoir computing. This innovation utilizes the molecular vibrations of a select number of organic molecules.

Traditional memory devices are volatile and the current non-volatile ones rely on either ferromagnetic or ferroelectric materials for data storage. In ferromagnetic devices, data is written or stored by aligning magnetic moments, while in ferroelectric devices, data storage relies on the alignment of electric dipoles.

Self-assembling molecules that spontaneously organize themselves to form complex structures are common in nature. For example, the tough outer layer of insects, called the cuticle, is rich in proteins that can self-assemble.

An unexpected discovery surprised a scientist at the Max Planck Institute for Intelligent Systems in Stuttgart: Nanometer-sized diamond particles, which were intended for a completely different purpose, shone brightly in a magnetic resonance imaging experiment—much brighter than the actual contrast agent, the heavy metal gadolinium.

Using an ultrasensitive photonic crystal, TU/e researchers were able to detect single particles down to 50 nanometers in diameter. The new research has just been published in the journal Optica.

A new imaging technique developed by engineers at Washington University in St. Louis can give scientists a much closer look at fibril assemblies—stacks of peptides that include amyloid beta, most notably associated with Alzheimer's disease.

Researchers have found that tiny particles present in cows' milk could offer, for the first time, an effective method for the oral delivery of RNA drugs.

Researchers at the University of São Paulo (USP) in Brazil have developed a bioelectronic chip that simultaneously detects vitamins C and D in body fluids. It is flexible and easy to see and can be adapted for use in a wearable device to assist with a personalized diet. Details are described in an article published in ACS Applied Nano Materials.

As a typical two-dimensional material, MoS2 exhibits unique optical and electrical properties due to its atomic thickness in the vertical dimension, making it a research hotspot in the field of optoelectronic detection.

The need for sustainable and environment-friendly solutions has accelerated the global demand for green and renewable technologies. In this regard, semiconductor photocatalysts have emerged as an attractive solution, owing to their potential in mitigating pollutants and harnessing solar energy efficiently. Photocatalysts are materials that initiate chemical reactions when exposed to light.

Molecular computer components could represent a new IT revolution and help us create cheaper, faster, smaller, and more powerful computers. Yet researchers struggle to find ways to assemble them more reliably and efficiently.
