New insights into the energy levels in quantum dots

25 июня, 2020 - 17:25
Researchers have gained new insights into the energy states of quantum dots. They are semiconductor nanostructures and promising building blocks for quantum communication. With their experiments, the scientists confirmed certain energy transitions in quantum dots that had previously only been predicted theoretically: the so-called radiative Auger process.

Scientists home in on pairs of atoms that boost a catalyst's activity

22 июня, 2020 - 22:25
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.

Polymers can fine-tune attractions between suspended nanocubes

19 июня, 2020 - 18:57
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.

Researchers create a photographic film of a molecular switch

18 июня, 2020 - 20:23
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.

Nanoparticle for overcoming leukemia treatment resistance

18 июня, 2020 - 19:01
One of the largest problems with cancer treatment is the development of resistance to anticancer therapies. A research team found that repurposing a commonly used chemotherapy drug using a nanoparticle was more effective than both a solution of the pure drug and other available treatments.
