  • Turning pollen into a low-cost fertilizer ۱۳۹۶/۵/۲۵

    As the world population continues to balloon, agricultural experts puzzle over how farms will produce enough food to keep up with demand. One tactic involves boosting crop yields. Toward that end, scientists have developed a method to make a low-cost, biocompatible fertilizer with carbon dots derived from rapeseed pollen. The study, appearing in ACS Omega, found that applying the carbon dots to hydroponically cultivated lettuce promoted its growth by 50 percent. 

  • Nanotechnology gives green energy a green color ۱۳۹۶/۵/۲۴

    Solar panels have tremendous potential to provide affordable renewable energy, but many people see traditional black and blue panels as an eyesore. Architects, homeowners and city planners may be more open to the technology if they could install green panels that melt into the landscape, red panels on rooftops and white ones camouflaged as walls.

  • New ultrathin semiconductor materials exceed some of silicon's 'secret' powers ۱۳۹۶/۵/۲۰

    The next generation of feature-filled and energy-efficient electronics will require computer chips just a few atoms thick. For all its positive attributes, trusty silicon can't take us to these ultrathin extremes.

  • Big impact, tiny element—hydrogen power on the nanoscale ۱۳۹۶/۵/۱۱

    Using hydrogen for energy production is nothing new. But with his research, Carnegie Mellon University Materials Science and Engineering (MSE) Ph.D. candidate Ajay Pisat hopes to unlock its full potential as a primary, mainstream energy storage medium by maximizing the efficiency of hydrogen production through photocatalysis.

  • Spin dynamics of graphene explained through supercomputing ۱۳۹۶/۵/۱۱

    In a previous study, researchers found evidence to suggest that spin-orbit coupling (SOC) was greater in graphene/transition metal dichalcogenide heterostructures than in regular graphene. In principle, this phenomenon is a necessary prerequisite for the spin Hall effect (SHE), yet subsequent tests to measure the system's SHE gave inconclusive results. In a paper published this July in NanoLetters, researchers of the ICN2 Theoretical and Computational Nanoscience Group, led by ICREA Prof. Stephan Roche, were able to confirm the observations of an enhanced SOC, as well as propose a reasonable explanation as to why the SHE could not be measured experimentally.

  • Gold nanostars and immunotherapy vaccinate mice against cancer ۱۳۹۶/۵/۲۶

    By combining an FDA-approved cancer immunotherapy with an emerging tumor-roasting nanotechnology, Duke University researchers improved the efficacy of both therapies in a proof-of-concept study using mice.

  • Going nano in the fight against cancer ۱۳۹۶/۵/۲۶

    Imagine being able to see the signs of cancer decades before we can now. URI Chemical Engineering Assistant Professor Daniel Roxbury and researchers from Memorial Sloan Kettering Cancer Center have invented a technique that could detect a wide range of biomarkers that signal the start of cancer—many years before symptoms surface.

  • Fizzy soda water could be key to clean manufacture of flat wonder material: graphene ۱۳۹۶/۵/۲۶

    Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials—graphene.

  • Boron nitride foam soaks up carbon dioxide ۱۳۹۶/۵/۲۵

    Rice University materials scientists have created a light foam from two-dimensional sheets of hexagonal-boron nitride (h-BN) that absorbs carbon dioxide.

  • Gold shines through properties of nano biosensors ۱۳۹۶/۵/۲۵

    With their remarkable electrical and optical properties, along with biocompatibility, photostability and chemical stability, gold nanoclusters are gaining a foothold in a number of research areas, particularly in biosensing and biolabeling.
