Quick and easy preparation of small-sized metal nanoparticles by microchip laser
Pulsed laser ablation in liquid (PLAL) is a reliable and versatile technique for producing metal nanoparticles (NPs) in solution. Its advantages, including the absence of reducing agents, operational simplicity, high purity without purification steps.....»»
Locusts" sense of smell boosted with custom-made nanoparticles
Our sensory systems are highly adaptable. A person who cannot see after turning off a light in the night slowly achieves superior power to see even small objects. Women often attain a heightened sense of smell during pregnancy. How can the same senso.....»»
Spatial model predicts bumblebee exposure to pesticide use
It has long been known that agricultural pesticides are one of the greatest threats to bees and other essential pollinators. What farmers have lacked is an understanding of how different pesticides, applied at various times on a variety of crops, aff.....»»
Environmental risks of new pesticides with nanoparticles insufficiently examined, say researchers
The environmental risks of new pesticides containing nanoparticles are inadequately researched, according to four Leiden University scientists, who have published an article in the journal Environmental Science & Technology. They call for an examinat.....»»
iPhone app sideloading: Apple reportedly plans to charge fees and review apps downloaded outside of the App Store
Apple will soon announce policy changes to conform to the Digital Markets Act in Europe, with an impending implementation deadline of March. The DMA will force Apple to allow iPhone app sideloading, with the goal of reducing Apple’s monopolistic co.....»»
Researchers uncover molecular mechanisms behind effects of MXene nanoparticles on muscle regeneration
Tissue engineering, which involves the use of grafts or scaffolds to aid cell regeneration, is emerging as a key medical practice for treating volumetric muscle loss (VML), a condition where a significant amount of muscle tissue is lost beyond the bo.....»»
