Traditional fluorescent dyes to examine bacteria viability are toxic and suffer poor photostability - but using the Vortex Fluidic Device has enabled the preparation of a new generation of aggregation-induced emission dye luminogens using graphene oxide.
A study identified which pairs of atoms in a catalyst nanoparticle are most active in a reaction that breaks down a harmful exhaust gas in catalytic converters. The most active particles contained the biggest proportion of one particular atomic configuration -- one where two atoms, each surrounded by seven neighboring atoms, form pairs to carry out the reaction steps. The results are a step toward engineering cheaper, more efficient catalysts.
Light interacts with itself to form self-sustaining waves in an artificial topological material.
Engineers have created a light-powered catalyst that can break the strong chemical bonds in fluorocarbons, a group of synthetic materials that includes persistent environmental pollutants.
'Janus' nanorods convert light to heat that can destroy pollutants.
Biophysicists have developed a high-throughput super-resolution microscope to probe nanoscale structures and dynamics of mammalian cells, showing in unprecedented detail the twists and turns of an organelle important for cell division.
Researchers discovered a new way to engineer optoelectronic devices by stretching a two-dimensional material on top of a silicon photonic platform.
Researchers report that a fabrication technique may offer a path toward mastering the often chaotic flow of heat carriers at the nanoscale in silicon and other semiconductors.
Researchers create first efficient 2D material photodetector for telecom wavelengths.
When hit with light, the film-thin materials come alive -- bending, rotating and even crawling on surfaces.
Researchers have created a Bose-Einstein condensate with record speed, creating the fascinating phase of matter in about 100 femtoseconds.
Electrons in chiral crystals, solid-state materials with definite handedness, can behave in unexpected ways. An interdisciplinary research team has realized now a theoretically predicted peculiar electronic state in a chiral compound, PtGa, from the class of topological materials.
The particles will be produced using 3D-bioprinting, enabling them to be released at specified intervals, instead of a continuous slow release.
Interactions between hollow silica nanocubes suspended in a solution can be adjusted by varying the concentration of polymer molecules added to the mixture.
Researchers demonstrate a high level of control over a type of colloid in which the suspended particles take the form of hollow, nanoscale cubes. This case has only previously been explored through theoretical calculations.
The new study focuses on a production method, based around mechanical abrasion, where multilayer structures are formed through directly abrading different Van der Waals material powders directly on top of one another.
Ion-based technology may enable energy-efficient simulations of the brain's learning process, for neural network AI systems.
Researchers used single nanoparticles that illuminate single fluorescent molecules to detect ultrafast biochemical reactions.
What does it mean to design a science lab today? What are the new challenges for the architects of science buildings? And what is the best method to study the constantly evolving architectures of science?
Molecular switches are the molecular counterparts of electrical switches and play an important role in many processes in nature. Nanotechnologist now produced a photographic film at the atomic level and thus tracked the motion of a molecular building block. The result was a light-controlled 'pedalo-type motion', going forward and backward.
