Nanotechnology news
Calculations confirm that surface flaws are behind fluorescence intermittency in silicon nanocrystalsQuantum dots are nanoparticles of semiconductor that can be tuned to glow in a rainbow of colors. Since their discovery in the 1980s, these remarkable nanoparticles have held out tantalizing prospects for all kinds of new technologies, ranging from paint-on lighting materials and solar cells to quantum computer chips, biological markers, and even lasers and communications technologies. | |
New micro-supercapacitor structure inspired by the intricate design of leavesThere was a time during the early development of portable electronics when the biggest hurdle to overcome was making the device small enough to be considered portable. After the invention of the microprocessor in the early 1970s, miniature, portable electronics have become commonplace and ever since the next challenge has been finding an equally small and reliable power source. Chemical batteries store a lot of energy but require a long period of time for that energy to charge and discharge plus have a limited lifespan. Capacitors charge quickly but cannot store enough charge to work for long enough to be practical. One possible solution is something called a solid-state micro-supercapacitor (MSC). Supercapacitors are armed with the power of a battery and can also sustain that power for a prolonged period time. Researchers have attempted to create MSCs in the past using various hybrids of metals and polymers but none were suitable! for practical use. In more recent trials using graphene and carbon nanotubes to make MSCs, the results were similarly lackluster. | |
NIST 'how-to' website documents procedures for nano-EHS research and testingAs engineered nanomaterials increasingly find their way into commercial products, researchers who study the potential environmental or health impacts of those materials face a growing challenge to accurately measure and characterize them. These challenges affect measurements of basic chemical and physical properties as well as toxicology assessments. |

The cosmic start of lightningEven though lightning is a common phenomenon, the exact mechanism triggering a lightning discharge remains elusive. Scientists at the Dutch national research institute for mathematics CWI, the University of Groningen and the University of Brussels now published a realistic model involving large ice particles and cosmic rays. | |
How oversized atoms could help shrink"Lab-on-a-chip" devices – which can carry out several laboratory functions on a single, micro-sized chip – are the result of a quiet scientific revolution over the past few years. For example, they enable doctors to make complex diagnoses instantly from a single drop of blood. | |
Producing spin-entangled electronsA team from the RIKEN Center for Emergent Matter Science, along with collaborators from several Japanese institutions, have successfully produced pairs of spin-entangled electrons and demonstrated, for the first time, that these electrons remain entangled even when they are separated from one another on a chip. This research could contribute to the creation of futuristic quantum networks operating using quantum teleportation, which could allow information contained in quantum bits—qubits—to be shared between many elements on chip, a key requirement to scale up the power of a quantum computer. The ability to create non-local entangled electron pairs—known as Einstein-Podolsky-Rosen pairs—on demand has long been a dream. | |
Ultra-stable JILA microscopy technique tracks tiny objects for hoursJILA researchers have designed a microscope instrument so stable that it can accurately measure the 3D movement of individual molecules over many hours—hundreds of times longer than the current limit measured inseconds. | |
NASA collaborates with DRS Technologies to create mid-infrared detectorNASA scientist Xiaoli Sun and his industry partner have created the world's first photon-counting detector sensitive to the mid-infrared wavelength bands—a spectral sweet spot for a number of remote-sensing applications, including the detection of greenhouse gases on Earth, Mars and other planetary bodies, as well as ice and frost on comets, asteroids and the moon. | |
Groundbreaking research to help control liquids at micro and nano scalesFrom targeted drug delivery to the self-assembly of nano robots, new research by Northumbria University, Newcastle, is using super-sized atoms to reveal the behaviour of liquids in microscopic channels. | |
Influential interfaces lead to advances in organic spintronicsSpintronics is an emerging field of electronics in which devices work by manipulating the quantum mechanical spin of electrons, in addition to their elementary electric charge. Just as conventional transistors have a source of electrons, a gate to control their movement, and a drain to carry off the charge signal, a spintronic circuit needs a well-controlled source of spin-polarized electrons that are injected into a transport channel material, a well-defined method of controlling the spin through the material, and a system to detect the spin signal. Additionally, it requires a transport channel material with long spin lifetimes because (polarized) spins fade away (i.e., become randomized) and lose their information during transport, unlike electric charges. | |
Improving insulation materials, down to wetting crossed fibersSandcastles are a prime example of how adding a small amount of liquid to a granular material changes its characteristics. But understanding the effect of a liquid wetting randomly oriented fibres in a fibrous medium remains a mystery. Relevant to the building industry, which uses glass wool, for instance, this phenomenon can be better understood by studying the behaviour of a liquid trapped between two parallel fibres. It can either remain in the shape of a drop or spread between the fibres into a long and thin column of liquid. Now, scientists have demonstrated that the spreading of the liquid is controlled by three key parameters: the amount of liquid on the fibres, the fibres' orientation and the minimum distance between them. | |
Clues to inner atomic life from subtle light-emission shiftsAtoms absorb and emit light of various wavelengths. Physicists have long known that there are some tiny changes, or shifts, in the light that gets absorbed or emitted, due to the properties of the atomic nucleus. | |
Restoration of NIST's million-pound deadweight machineRestoration is well underway for NIST's 4.45-million newton (equivalent to one million pounds-force) deadweight machine, the largest in the world.

New method can make cheaper solar energy storageStoring solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems. To accomplish this, traditional solar panels can be used to generate an electrical current that splits water molecules into oxygen and hydrogen, the latter being considered a form of solar fuel. However, the cost of producing efficient solar panels makes water-splitting technologies too expensive to commercialize. EPFL scientists have now developed a simple, unconventional method to fabricate high-quality, efficient solar panels for direct solar hydrogen production with low cost. | |
Scientists unravel elusive structure of HIV proteinHIV, or human immunodeficiency virus, is the retrovirus that leads to acquired immunodeficiency syndrome or AIDS.

Scientists reveal different dynamics of droplet formation on fibersThin fibers play a tremendous role in many areas of our daily life, from the use of glass fibers in ultra-fast data transmission to textile fibers in our clothing. In order to enable special properties of these fibers, they are often coated with a thin liquid layer that is supposed to be stable and homogeneous. However, for the production of drinkable water, the exact opposite features are desired: there, one aims at harvesting water, which is transported along the fiber as a liquid film or as liquid droplets, from fog. Now, scientists have been able to reveal, by means of lacquer films on glass fibers, whether liquid films slowly flow along the fiber or if they can slip faster on the fiber. The team composed of Karin Jacobs and Sabrina Haefner from Saarland University, together with Oliver Bäumchen from the Max Planck Institute for Dynamics and Self-Organization in Göttingen, and colleagues from Canada and France have been able! to show for the first time, by means of novel experiments and mathematical models, how a liquid film moves on a fiber, depending on the fiber coating. | |

Why human egg cells don't age wellWhen egg cells form with an incorrect number of chromosomes—a problem that increases with age—the result is usually a miscarriage or a genetic disease such as Down syndrome. Now, researchers at the RIKEN Center for Developmental Biology in Japan have used a novel imaging technique to pinpoint a significant event that leads to these types of age-related chromosomal errors. Published in Nature Communications, the study shows that as egg cells mature in older women, paired copies of matching chromosomes often separate from each other at the wrong time, leading to early division of chromosomes and their incorrect segregation into mature egg cells. | |

Restaurant meals can be as bad for your waistline as fast food isWhen Americans go out to eat, either at a fast-food outlet or a full-service restaurant, they consume, on average, about 200 more calories a day than when they stay home for meals, a new study reports. They also take in more fat, saturated fat, cholesterol and sodium than those who prepare and eat their meals at home. | |
Lifelong learning is made possible by recycling of histones, study saysNeurons are a limited commodity; each of us goes through life with essentially the same set we had at birth. But these cells, whose electrical signals drive our thoughts, perceptions, and actions, are anything but static. They change and adapt in response to experience throughout our lifetimes, a process better known as learning. | |
Seeing is believing: How brains make sense of the visual worldIf your eyes deceive you, blame your brain. Many optical illusions work because what we see clashes with what we expect to see. | |
Human brain may contain a map for social navigationThe brain region that helps people tell whether an object is near or far may also guide how emotionally close they feel to others and how they rank them socially, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published today in the journal Neuron. The findings promise to yield new insights into the social deficits that accompany psychiatric disorders like schizophrenia and depression. | |
Revised view of brain circuit reveals how we avoid being overwhelmed by powerful odorsYou've just encountered a frightened skunk, which has sprayed a generous quantity of its sulfur-containing scent directly in your path.

New health evidence gives women informed choice in the stress urinary incontinence surgery debateA new Cochrane systematic review published today of surgery for stress urinary incontinence makes an important contribution to an ongoing debate and will help women to make more informed choices about treatment. Inserting a 'mid-urethral sling', a type of tape, to support the muscles of the bladder by either the groin or abdomen results in similar cure rates. However, differences in complications and the long term need for repeat surgery mean that women will need to balance a number of different factors when choosing an operation. | |
Extracurricular sports produce disciplined preteensRegular, structured extracurricular sports seem to help kids develop the discipline they need in order to engage effectively in the classroom, according to a new study led by Linda Pagani of the University of Montreal and its affiliated CHU Sainte-Justine children's hospital. "We worked with information provided by parents and teachers to compare kindergarteners' activities with their classroom engagement as they grew up," Pagani said. "By time they reached the fourth grade, kids who played structured sports were identifiably better at following instructions and remaining focused in the classroom. There is something specific to the sporting environment - perhaps the unique sense of belonging to a team to a special group with a common goal - that appears to help kids understand the importance of respecting the rules and honoring responsibilities." | |

Live imaging reveals how wound healing influences cancerResearchers in the United Kingdom and Denmark have studied the "see-through" larvae of zebrafish to reveal how wound healing leads to skin cancer. Live imaging shows neutrophils, the protective inflammatory cells of the body's immune system, diverted from an induced wound to any nearby precancerous skin cells. The newly arrived neutrophils cause rapid division of these skin cells, which may cause them to progress to melanoma. The results are published in The EMBO Journal. | |
Miniature pump regulates internal ocular pressureElevated or diminished eye pressure impairs our ability to see, and in the worst cases, can even lead to blindness. Until now, there has been no effective long-term treatment.

Researchers develop a computer model to explain how nerve cell connections form in the visual cortexWhen newborn babies open their eyes for the first time, they already possess nerve cells specialized in particular stimuli in the visual cortex of their brains - but these nerve cells are not systematically linked with each other. How do neural networks that react in a particular way to particular features of a stimulus develop over the course of time? In order to better understand the steps of this development and explain the complicated processes of reorganization they involve, an international team of researchers has now developed a computer model that precisely simulates the biological processes. The results of the study by Prof. Dr. Stefan Rotter, Bernstein Center Freiburg (BCF) and Cluster of Excellence BrainLinks-BrainTools of the University of Freiburg, conducted in cooperation with Dr. Claudia Clopath from the Imperial College London, England, have now been published in the journals PLOS Computational Biology and PLOS ONE! . | |

Subcutaneous administration of multispecific antibody makes tumor treatment faster and more tolerableTumor treatment with multispecific antibodies is significantly more tolerable if administered subcutaneously rather than via the bloodstream, which was the standard procedure until now. This was the result of an animal model study undertaken by researchers at Helmholtz Zentrum München in cooperation with the Munich biotech company Trion Research. According to the scientists, the findings published in the journal Molecular Cancer Therapeutics could lead to shorter hospital stays, among other benefits for patients. | |
How the stress hormone cortisol reinforces traumatic memoriesThe stress hormone cortisol strengthens memories of scary experiences. However, it is effective not only while the memory is being formed for the first time, but also later when people look back at an experience while the memory reconsolidates. This has been published by cognition psychologists from the Ruhr-Universität Bochum in the journal Neuropsychopharmacology. They suggest that the results might explain the persistence of strong emotional memories occurring in anxiety and Post-Traumatic Stress Disorder (PTSD). | |

Dagger-like canines of saber-toothed cats took years to growNew research shows that the fearsome teeth of the saber-toothed cat Smilodon fatalis fully emerged at a later age than those of modern big cats, but grew at a rate about double that of their living relatives. The findings, published today in the journal PLOS ONE and based on a new technique that combines isotopic analysis and x-ray imaging, for the first time provide specific ages for developmental events in Smilodon, notably in their teeth. The study estimates that the eruption rate of S. fatalis's permanent upper canines was 6 millimeters per month—double the growth rate of an African lion's teeth. But the extinct cat's dagger-like canines weren't fully developed until about three years of age. | |
