'Growth and yield performance of drought-stressed soybean ( Glycine max L.) treated with neem-mediated silver nanoparticles' - an article in the @EDPSciences UN #SDGs #Research collection on #ScienceOpen:

ScienceOpenGrowth and yield performance of drought-stressed soybean ( <i>Glycine max</i> L.) treated with neem-mediated silver nanoparticles<p xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="first" dir="auto" id="d9219553e162">The utilization of nanotechnology in agriculture has demonstrated significant potential, particularly in enhancing crop resilience to environmental stress. This study investigated the effect of silver nanoparticles (AgNPs) in seed treatment on soybean performance under drought conditions. The study used a factorial CRD with four replicates. The experimental factors included seed treatments (control, AgNP priming, and AgNP coating) and drought stress levels represented by the field water capacity (FWC) of 80%, 60%, and 40%. The results demonstrated that seed treatment with AgNPs significantly increased plant growth in AgNP coatings based on plant height but did not significantly increase all soybean yield variables. FWC of 40-60% showed severe and moderate stress effects on soybean, which significantly decreased the leaf number but increased the leaf green index. In conclusion, AgNP seed treatment had a limited effect on soybean production but could be a potential approach to enhance drought tolerance. </p>

New #nanotechnology entry for the Historical #Dictionary of #ScienceFiction: "gray goo", which I've been sitting on for years because of bibliographical issues.

(Basically, this is always credited to K. Eric Drexler's _Engines of Creation_, but it was used early by a journalist who was embedded in Drexler's group at MIT.)

Does anyone feel like they need the world's smallest violin? Loughborough University in the U.K. can help with that. Physicists there used nanotechnology to create an image of a fiddle that is smaller than the width of a human hair. To do it, the team used a small chip, onto which the design was etched using a machine called a NanoFrazor. Prof. Kelly Morrison, head of the university's physics department, says this work will help with research into everything from the efficiency of computers to new ways of harvesting energy. Here's more from @BBCNews.

nanotechnologyworld · Scientists discover class of crystals with properties that may prove revolutionaryAs described in a report in the science journal Nature Materials, the scientists stacked two ultrathin layers of graphene, each a one-atom-thick sheet of carbon atoms arranged in a hexagonal grid. They twisted them slightly atop a layer of hexagonal boron nitride, a hexagonal crystal made of boron and nitrogen. A subtle misalignment between the layers that formed moiré patterns – patterns similar to those seen when two fine mesh screens are overlaid – significantly altered how electrons moved...

Plastics rivaling steel? 🌟 Advances in polymer nanocomposites, high-performance polymers like PEEK, & biomimetic materials are redefining strength, flexibility & self-healing. Key to industrial innovation. #PolymerScience #MaterialsInnovation #Nanotechnology #Sustainability #Engineering
t.co/LBPSe6MrrV

ZenodoBeyond Metal: The New Age of PlasticsThis comprehensive analysis examines the frontier of high-performance plastic development with mechanical properties approaching or rivaling steel. Our research identifies significant advances in polymer nanocomposites, highly oriented polymer systems, and biomimetic approaches that have collectively narrowed the performance gap between plastics and metals. The incorporation of nanomaterials has enabled unprecedented improvements in tensile strength, with some polymer composites achieving values exceeding 300 MPa. Highperformance polymers like PEEK demonstrate remarkable thermal stability at temperatures above 260°C while maintaining mechanical integrity. Biomimetic approaches have yielded materials with unique combinations of strength, flexibility, and self-healing capabilities. This analysis presents comprehensive mechanical property comparisons, examines scale-up challenges, and evaluates commercial viability across multiple industrial sectors
