Lithium-ion Battery Capacity Could Get Boost From Yolk-and-shell Nanoparticle

One big problem with electrodes in rechargeable batteries, going through cycles of charging and discharging, is they must expand and shrink during each cycle, sometimes doubling in volume, and then shrinking back. This leads to repeated shedding and reformation of the electrode’s “skin” layer that irreversibly consumes lithium, degrading the battery’s performance over time. But…Continue readingLithium-ion Battery Capacity Could Get Boost From Yolk-and-shell Nanoparticle

Nanoparticle Spiked Bacteria Emit Hard X-rays

Bacteria that emit intense, hard X-ray radiation have been created by researchers at the Tata Institute of Fundamental Research, and Institute for Plasma Research. Usually when you hear the words X-rays and bacteria in the same sentence, the bacteria are at the receiving end of the X-ray source, being imaged, irradiated for some treatment, or…Continue readingNanoparticle Spiked Bacteria Emit Hard X-rays

Engineered Nanoparticles In Surface Waters Get World’s First Model

The world’s first spatiotemporally accurate model for simulating behaviour and of engineered nanoparticles in surface waters has been created by researchers of Wageningen University. Nanotechnology is developing fast. Emissions of less than 100 nm engineered nanoparticles (ENPs) are also growing as a result. Measuring ENP levls in the environment is very challenging, so exposure evaluations…Continue readingEngineered Nanoparticles In Surface Waters Get World’s First Model

Nanoparticles Protect Myeloma Drug In Blood From Breakdown

A novel drug therapy based on nanoparticles is effectively treating mice with multiple myeloma, a cancer of bone marrow immune cells, Washington University in St. Louis researchers say. Specifically designed to target the malignant cells, the nanoparticles guard their therapeutic load from degrading in the bloodstream, and enhance drug delivery into the cancer cells. In…Continue readingNanoparticles Protect Myeloma Drug In Blood From Breakdown

Nanoparticle Superlattices With DNA-mediated Reprogramming

Dynamic nanomaterials with structures and properties that can be switched on demand have now become one step closer to reality. In a new paper, scientists at Brookhaven National Laboratory detail a method to selectively rearrange nanoparticles in three-dimensional arrays to create different configurations, or phases, from the same nano-components. Study leader Oleg Gang, of Brookhaven’s…Continue readingNanoparticle Superlattices With DNA-mediated Reprogramming

Silver Nanoparticles Antibacterial Activity Holds Promise

For centuries, precious metals such as gold and silver have been thought to have biomedical properties. But do these materials effectively combat cancer and bacteria? And if so, how do they do it without contaminating the patient and the environment with toxins? Peng Zhang, Associate Professor of Chemistry at Dalhousie Univesity, is searching for the…Continue readingSilver Nanoparticles Antibacterial Activity Holds Promise
