| | 1. Bringing superconducting nanostructures to 3D19:02[-/+]Категория(?) | The move from two to three dimensions can have a significant impact on how a system behaves, whether it is folding a sheet of paper into a paper airplane or twisting a wire into a helical spring. At the nanoscale, 1,000 times smaller than a human hair, one approaches the fundamental length scales of, for example, quantum materials. Медиа: image / jpg | ↑ |
2. Stability solution brings unique form of carbon closer to practical application18:54[-/+]Категория(?) | Carbyne, a one-dimensional chain of carbon atoms, is incredibly strong for being so thin, making it an intriguing possibility for use in next-generation electronics, but its extreme instability causing it to bend and snap on itself made it nearly impossible to produce at all, let alone produce enough of it for advanced studies. Now, an international team of researchers, including from Penn State, may have a solution. Медиа: image / jpg | ↑ |
3. Self-assembled dodecahedral nanostructure features 60 metal ions and peptide ligands18:46[-/+]Категория(?) | Controlling the topology and structure of entangled molecular strands is a key challenge in molecular engineering, particularly when attempting to create large nanostructures that mimic biological systems. Examples found in nature, such as virus capsids and cargo proteins, demonstrate the remarkable potential of such architectures. However, methods for constructing large hollow nanostructures with precise geometric control have remained elusive—until now. Медиа: image / jpg | ↑ |
9. Revolution in friction: A way to make super-smooth materialsСр, 07 мая[-/+]Категория(?) | Scientists from the Faculty of Physics and Applied Informatics at the University of Lodz have published an article on friction in the journal Small. Their research on "bismuth islands" moving on the surface of graphite confirmed the existence of a totally new form of so-called superlubricity—a friction-free contact between two solid bodies.

12. Micropipette uses targeted ion delivery to activate individual neuronsСр, 07 мая[-/+]Категория(?) | Researchers at Linkoping University have developed a new type of pipette that can deliver ions to individual neurons without affecting the sensitive extracellular milieu. Controlling the concentration of different ions can provide important insights into how individual braincells are affected, and how cells work together. The pipette could also be used for treatments.

15. Deep-trench 3D printing enables next-gen RF devices with unprecedented precisionВт, 06 мая[-/+]Категория(?) | For decades, traditional lithography techniques—such as electron beam lithography and nanoimprinting—have struggled to meet the demand for ultra-fine, high-aspect-ratio structures in general. Similar difficulty also applies to metal-based radio-frequency (RF) components. Issues like poor thickness control, uneven sidewalls, and material limitations have constrained performance and scalability. Медиа: image / jpg | ↑ |
16. It's hard to get meds to the lungs: Breathable algae offers a new pathВт, 06 мая[-/+]Категория(?) | Our lungs are fairly susceptible to diseases. Unlike most other organs, the lungs are in direct contact with the outside world. When we breathe in, our lungs can also take in things besides the oxygen we need, including irritants, pollutants, viruses and bacteria which may cause diseases like pneumonia, bronchitis and cancer.

17. Physicists create ultra-stretchable graphene via an accordion-like rippling effectВт, 06 мая[-/+]Категория(?) | Graphene is a "miracle material": mechanically extremely strong and electrically highly conductive, ideal for related applications. Using a unique method, physicists at the University of Vienna led by Jani Kotakoski have for the first time made graphene drastically more stretchable by rippling it like an accordion. This paves the way for new applications in which certain stretchability is required (e.g. wearable electronics). Медиа: image / jpg | ↑ |
19. Low-coordination Mn single-atom nanozymes enable imaging-guided cancer therapyВт, 06 мая[-/+]Категория(?) | A research team led by Prof. Wang Hui from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS), in collaboration with researchers led by Prof. Qian Junchao from HFIPS and Prof. Qu Songnan from the University of Macau, has successfully developed a novel low-coordination single-atom manganese nanozyme using a unique "molecular carbonization-reduction" strategy.

20. An electronic band-aid that delivers therapy directly to organsВт, 06 мая[-/+]Категория(?) | A team of biomedical engineers from China and the U.S. has developed a thin patch resembling a band-aid that can be applied to an internal organ to directly deliver therapeutic drugs. In their paper published in the journal Nature, the group describes the factors that went into the development of their patch, its construction and its capabilities. Медиа: image / jpg | ↑ |
23. AI-powered electronic nose detects diverse scents for health care and environmental applicationsПт, 02 мая[-/+]Категория(?) | A research team has developed a "next-generation AI electronic nose" capable of distinguishing scents like the human olfactory system does and analyzing them using artificial intelligence. This technology converts scent molecules into electrical signals and trains AI models on their unique patterns. It holds great promise for applications in personalized health care, the cosmetics industry, and environmental monitoring. Медиа: image / jpg | ↑ |
24. Unique molecule may lead to smaller, more efficient computersПт, 02 мая[-/+]Категория(?) | Today, most of us carry a fairly powerful computer in our hand—a smartphone. But computers weren't always so portable. Since the 1980s, they have become smaller, lighter, and better equipped to store and process vast troves of data. Yet the silicon chips that power computers can only get so small. Медиа: image / jpg | ↑ |
25. Precision-engineered surface can enhance silicon solar cell performanceЧт, 01 мая[-/+]Категория(?) | Converting sunlight into electricity is the task of photovoltaic solar cells, but nearly half the light that reaches a flat silicon solar cell surface is lost to reflection. While traditional antireflective coatings help, they only work within a narrow range of light frequency and incidence angles. A new study may have overcome this limit. Медиа: image / jpg | ↑ |
28. Tiny technology that can find pollution in South Africa's water and trap itЧт, 01 мая[-/+]Категория(?) | Nanotechnology is the use of materials that are one-billionth of a meter (a nanometer) in size. One of its potential uses is to clean up whatever is contaminating water supplies. Analytical chemist Philiswa Nomngongo, a leading researcher in nanotechnology for water in South Africa, tells The Conversation Africa what kinds of devices are being produced with nanotechnology and what they can do.
