Three University of Chicago chemistry professors hope that their separate research trajectories will converge to create a new way of assembling what they call "designer atoms" into materials with a broad array of potentially useful properties and functions.
Quantum computing, where bits of information, or 'qubits', are represented by the state of single atomic particles or photons of light, won't be of much use unless we can read the results. Cornell researchers have taken a step in that direction with a device that can measure the presence of just a few photons without disturbing them.
A microscale technique known as optical trapping uses beams of light as tweezers to hold and manipulate tiny particles. Stanford researchers have found a new way to trap particles smaller than 10 nanometers - and potentially down to just a few atoms in size - which until now have escaped light's grasp.
To date, nanoparticle-based drug delivery approaches have been poorly developed for the treatment of childhood leukemia, which comprises 30% of childhood cancers. In the Nemours study, encapsulated dexamethasone ("dex") delivered to pre-clinical models with leukemia significantly improved quality of life and survival compared to the control receiving the unencapsulated drug.
A Monash University study led by Professor Dan Li has established, for the first time, an effective way of forming graphene, which normally exists in very thin layers, into useful three-dimensional forms by mirroring the structure of cork.
