Researchers can now convert CO2 from the air directly into methanol fuel - 2 views

  •  
    For the first time, researchers have shown that they can capture CO2 from the air, and convert it directly into methanol, which can then be used as an alternative fuel, as well as for hydrogen storage, in fuel cells, or as a building block for plastic.
  •  
    Solar power to suck out co2 during the day and make it fuel finally solves global warming?

Trends in Biomimetics - 0 views

  •  
    "The field of biomimicry mostly involves chemists, engineers and materials scientists. Fewer than 8% of the nearly 300 studies on biomimetics published in the past 3 months and indexed in the Thomson Reuters Web of Science had an author working in a biology department - a crude proxy for 'a biologist'."

Caltech Researchers Find Evidence of a Real Ninth Planet | Caltech - 0 views

  •  
    Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun at an average distance of 2.8 billion miles).

Material could harvest sunlight by day, release heat on demand hours or days later - 5 views

  •  
    Imagine if your clothing could, on demand, release just enough heat to keep you warm and cozy, allowing you to dial back on your thermostat settings and stay comfortable in a cooler room. Or, picture a car windshield that stores the sun's energy and then releases it as a burst of heat to melt away a layer of ice.
  •  
    interesting indeed: Such chemically-based storage materials, known as solar thermal fuels (STF), have been developed before, including in previous work by Grossman and his team. But those earlier efforts "had limited utility in solid-state applications" because they were designed to be used in liquid solutions and not capable of making durable solid-state films, Zhitomirsky says. The new approach is the first based on a solid-state material, in this case a polymer, and the first based on inexpensive materials and widespread manufacturing technology.

New theory allows drones to see distances with one eye - 2 views

  •  
    Inspired by the work that was done at the ACT, I continued working on optical flow landing at TU Delft. Today Bio & Bio published my article on a new theory that allows drones to see distances with a single camera. It shows that drones approaching an object with an insect-inspired vision strategy become unstable at a specific distance from the object. Turning this weakness into a strength, drones can actually use the timely detection of that instability to estimate distance. The new theory will enable further miniaturization of autonomous drones and provides a new hypothesis on flying insect behavior.

The physics of life - 2 views

  •  
    Research in active-matter systems is a growing field in biology. It consists in using theoretical statistical physics in living systems such as molecule colonies to deduce macroscopic properties. The aim and hope is to understand how cells divide, take shape and move on these systems.
    Being a crossing field between physics and biology "The pot of gold is at the interface but you have to push both fields to their limits." one can read
  •  
    Maybe we should discuss about this active matter one of these days?

    "These are the hallmarks of systems that physicists call active matter, which have become a major subject of research in the past few years. Examples abound in the natural world - among them the leaderless but coherent flocking of birds and the flowing, structure-forming cytoskeletons of cells. They are increasingly being made in the laboratory: investigators have synthesized active matter using both biological building blocks such as microtubules, and synthetic components including micrometre-scale, light-sensitive plastic 'swimmers' that form structures when someone turns on a lamp. Production of peer-reviewed papers with 'active matter' in the title or abstract has increased from less than 10 per year a decade ago to almost 70 last year, and several international workshops have been held on the topic in the past year."

Scientists teach bacterium a new trick for artificial photosynthesis - 1 views

  •  
    Berkeley Lab researchers are using M. thermoacetica to perform photosynthesis - despite being non-photosynthetic - and also to synthesize semiconductor nanoparticles in a hybrid artificial photosynthesis system for converting sunlight into valuable chemical products.

The Worlds Smallest Thermometer - 0 views

  •  
    By attaching a diamond crystal to an AFM tip, researcher at New York City University managed to measure the heat flows at atomic levels in resistors.
    The method works due to a vacancy in the carbon lattice, two spots are empty of which one is filled with a nitrogen atom. The energy state of the vacancy is temperature dependent and can actually be read out spectroscopically.

CO2 capture from humid gases - 0 views

  •  
    Researchers have managed to create a materials that can extract CO2 from a humid environment, which was up to now not possible due to water blocking the absorption. With this hurdle taken, it may be possible to extract CO2 in large quantities from the atmopshere. This would then either be stored or possible even processed with H2 to form carbohydrates. Marsian atmosphere?

Researchers find new phase of carbon, make diamond at room temperature - 1 views

  •  
    Researchers from North Carolina State University have discovered a new phase of solid carbon, called Q-carbon, which is distinct from the known phases of graphite and diamond. They have also developed a technique for using Q-carbon to make diamond-related structures at room temperature and at ambient atmospheric pressure in air.

    It turns out this configuration is harder than diamond, plus the material has a very low work function. The latter might be very interesting for electronics or as electrode material.
  •  
    Maybe* this is the wonder material with very low workfunction needed in the Photon Enhanced Thermionic Emitter future prototype :)

Can physical exercise enhance long-term memory? - 1 views

  •  
    Exercise can enhance the development of new brain cells in the adult brain, a process called adult neurogenesis. These newborn brain cells play an important role in learning and memory. A new study has determined that mice that spent time running on wheels not only developed twice the normal number of new neurons, but also showed an increased ability to distinguish new objects from familiar objects.

    wow ... time to start running again ...

Experimental evidence for new Flexo-electric nanomaterial - 1 views

  •  
    A new experiment proved the existence of a new effect in nanomaterials: flexo-electric effect. The material has built-in mechanical tension that changes shape when you apply electrical voltage, or that generates electricity if you change its shape and was theorized some decades ago.
    Now, SrTiO3 allowed to observe this new effect, being comparable with piezoelectric effect.

New derivation of pi links quantum physics and pure math - 5 views

  •  
    In 1655 the English mathematician John Wallis published a book in which he derived a formula for pi as the product of an infinite series of ratios. Now researchers from the University of Rochester, in a surprise discovery, have found the same formula in quantum mechanical calculations of the energy levels of a hydrogen atom.

Kilogram conflict resolved at last - 3 views

  •  
    Apparently it's time for retirement of the Le Grand K, if all goes well until the middle of next year...
  •  
    "One method (...) involves counting the atoms in two silicon-28 spheres that each weigh the same as the reference kilogram."
    Sounds like a lengthy task, but someone must keep those physics PhD students busy, I guess...

Watch Uranium Emit Radiation - 2 views

  •  
    You've heard of the catastrophic effects of radiation on environments, animals and humans. A seemingly silent and invisible destroyer, radiation can make whole cities inhabitable for hundreds of years. But have you ever wondered what radiation actually looks like? There may be one image that jumps to mind.

    We saw the same detector setup in the room opposite to ours during the Open Day! Using uranium is just cooler. :)
