The new technique enables 3D mapping of crystal structures inside nanomaterials with nanometer resolution, allowing for the study of their special properties and behavior under different conditions. This has significant implications for understanding and optimizing material properties in various applications.
Trapping prostate cancer stem cells with self-assembling nanomaterials inhibits colony formation and cell division in vitro. The approach may offer a new treatment strategy for metastatic hormone-refractory prostate cancer by targeting cancer stem cells, which are thought to be the origin of tumor metastasis.
A new report highlights the potential benefits of nanomaterials in construction, including improved strength, durability, and energy efficiency. However, concerns about adverse health and environmental effects also exist, emphasizing the need for guidelines to regulate their use.
Researchers analyzed over 140 studies on nanomaterials in construction and found benefits including increased strength and durability, as well as improved energy efficiency. However, concerns about potential health and environmental effects exist, highlighting the need for guidelines to regulate their use.
A new study by Rice University researchers highlights the vast potential of nanomaterials in the construction industry, from making more durable concrete to self-cleaning windows. The study also identifies potential adverse health and environmental effects, emphasizing the need for responsible lifecycle engineering.
The University of Nevada, Reno has developed a new curriculum that combines nanotechnology with skiing, aiming to prepare mechanical engineers for emerging challenges. Students will design and manufacture innovative materials and technologies to create extraordinary ski designs, including energy-efficient systems and dynamic structures.
The NIEHS has awarded 13 grants to develop better methods to assess exposure and health effects associated with nanomaterials. This research is essential for harmonizing results, forming a scientifically sound basis for hazard assessment.
ASU professors Stuart Lindsay and Paul Westerhoff will lead two innovative projects to tackle challenges in rapid DNA sequencing and nanotechnology health risks. The projects aim to simplify DNA sequencing like the invention of the transistor simplified electronics.
The new bill (H.R. 554) aims to improve federal risk research and oversight of engineered nanomaterials to protect the public and encourage safe commercial development. A National Research Council report highlighted serious shortfalls in the Bush administration's strategy, prompting Congress to take action.
A new report highlights the need for better toxicity data and private-sector outreach strategies to manage nanowaste. The EPA must conduct outreach to the private sector about how RCRA and CERCLA apply to nanomaterials, while firms and investors must consider emerging liabilities and environmental risks.
The FDA's Nanotechnology Task Force report highlights the challenges of regulating nanotechnology across various product categories. With over 500 manufacturer-identified nanotechnology consumer products being sold annually, the agency must ensure the safety of novel products before they enter the market.
The report emphasizes the need for life cycle assessments to ensure sustainable nanotechnology commercialization, citing limited data on nanomaterial toxicity and environmental impacts. LCA can still be useful, but uncertainties must be clearly stated to address critical unknowns.
The nanotechnology sector is expected to employ over 2 million workers by 2015, but risk research funding is limited, leading to a need for targeted studies on worker exposures. A 'control banding' approach could provide a middle ground between inaction and banning all nanomaterials as hazardous.
The US Department of Defense has funded the Texas Nanotechnology Consortium to develop and commercialize revolutionary nanomaterials for defense aerospace applications. The consortium will partner with the Air Force Research Laboratory to create next-generation composites and smart materials, ensuring US air superiority.
The International Council on Nanotechnology (ICON) has reviewed existing efforts to develop best practices for handling nanomaterials in the workplace. The Phase 1 report highlights the need for better information on industry practices, with some documents not publicly available.
The ICON-funded study aims to identify current nanotechnology standards and practices, with a focus on enhancing environmental and health safety. The research will provide essential data for companies in the US, Europe, and Asia, shedding light on new safety models and identifying areas where they are needed.
