Scientists have discovered highly conductive polymer behavior occurring at a polymer/nanocrystal interface. The composite organic/inorganic material is a thermoelectric and has a higher performance than either of its constituent materials. The results may impact not only thermoelectrics research, but also polymer/nanocrystal composites being investigated for photovoltaics, batteries, and hydrogen storage.

University of Illinois researchers have developed a new way to produce highly uniform nanocrystals used for both fundamental and applied nanotechnology projects.

From this week's C&EN, the President of the United States is skeptical about current data about chemical weapons use in Syria (article by Glenn Hess):Although “some evidence” has surfaced that chemical weapons have been used in Syria’s prolonged and intense civil war, it isn’t enough to warrant action, President Barack Obama said last week at a news briefing. Obama said more facts must be known before he is willing to consider any kind of escalation or U.S. involvement in

Seven years ago, Duke University engineers demonstrated the first working invisibility cloak in complex laboratory experiments. Now it appears creating a simple cloak has become a lot simpler.

A consortium of scientists from across the country has found that breathing ultrafine particles from a large family of materials that increasingly are found in a host of household and commercial products, from sunscreens to the ink in copy machines to super-strong but lightweight sporting equipment, can cause lung inflammation and damage.

RTI is expanding the utility of its Nanomaterial Registry by partnering with research organizations, universities, and industry in the nanomaterial research community to answer important questions on the connections between nanomaterial physical and chemical characteristics and nanomaterial benefits and risks.

Plants are amazing chemical factories. They take sunlight and use it and carbon dioxide to make energy for themselves. They also make oxygen, which we breathe. But they also make substances that can help heal us. Traditional Chinese medicine, for instance, makes use of herbs that are thought to have healing properties. And some drug companies use plant substances to make medicines — the breast cancer drug tamoxifen comes from the bark of the Pacific Yew tree. Now comes word that

Being able to control protein activity with respect to time and location with pulses of laser light has become an increasingly important scientific pursuit to understand how proteins work together. In a paper just out in the Journal of the American Chemical Society, researchers demonstrated a new fluorescent marker based on the well-known luciferase method. [...]

Columbia Engineering researchers have developed a technique to isolate a single water molecule inside a buckyball and to drive motion of the so-called 'big' nonpolar ball through the encapsulated 'small' polar H2O molecule, a controlling transport mechanism in a nanochannel under an external electric field. They expect this method will lead to an array of new applications, including effective ways to control drug delivery.

Most of the research efforts on developing synthesis methods for graphene has focused on flat substrates. However, direct growth of graphene layers on prepatterned substrates has remained elusive. In new work, resarchers have grown graphene in prepatterned copper-coated substrates, and they apply this protocol for the fabrication of MEMS devices, in particular, atomic force microscope probes. This layer of graphene improves the functionality of the probes by making them conductive and more […]

Researchers were able to detect for the first time a major contributing factor to this limitation: trace residues of catalyst material left over from the development process prevent the organic photovoltaics from converting the maximum amount of sunlight to electricity.

In the microscopic world, everything is in motion: atoms and molecules vibrate, proteins fold, even glass is a slow flowing liquid. And during each movement there are interactions between the smallest elements and their neighbours. To make these movements visible, scientists at the Paul Scherrer Institute have developed a special model system.

For the first time, researchers from institutions around the country have conducted an identical series of toxicology tests evaluating lung-related health impacts associated with widely used engineered nanomaterials (ENMs). The study provides comparable health risk data from multiple labs, which should help regulators develop policies to protect workers and consumers who come into contact with ENMs.

University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient photovoltaic solar cells and LED lights, biological sensors and systems to convert waste heat to electricity.

Every time a firefighter braves an inferno, a scientist wonders if a new material or special flame-resistant coating could be created to protect him. Today, armed with nanocomposite techniques and insights into bio-based materials, new classes of smart, adaptable super-surface coatings are possible, according to European researchers.

RBD Instruments recommends that you measure and also document the voltages on your card rack power supplies (located on the back right-hand electronic bay on most PHI systems) at least once per year. By monitoring these voltages you can notice … Continue reading →The post Card rack power supplies appeared first on RBD TechSpot.

My ebook, "Planetary Formation and Biogenesis" was first published on Amazon 1 year ago, it argues that quite a lot of the standard theory needs rethinking, in particular that initial accretion is dependent on chemistry, not gravity, and while I have found a number of otherwise puzzling observations for the standard theory, as far as I can tell, nothing I have found contradicts my propositions. Readers may forgive me, but I find that rather satisfying. Part of the reason, of course, […]
