Applications in imaging and sensing typically involve the emission of light at a different wavelength than the excitation, or 'secondary light emission'. The interpretation of resonant secondary light emission in terms of fundamental processes has been controversial for 40 years. In this work, researchers found that resonant electronic Raman scattering and resonant fluorescence may both be useful descriptions of the secondary emission.
Researchers at Case Western Reserve University have received a $540,000 federal grant to devise methods for building minute structures tailored to precisely deliver medicines to tumors or carry dyes that help imaging technologies detect disease, create more efficient nanowires and nanoelectonics, and more.
Researchers have constructed a detector, which provides a detailed picture of the waveforms of femtosecond laser pulses. Knowledge of the exact waveform of these pulses enables scientists to reproducibly generate light flashes that are a thousand times shorter - lasting only for attoseconds - and can be used to study ultrafast processes at the molecular and atomic levels.
Researchers have designed a micro-windmill that generates wind energy and may become an innovative solution to cell phone batteries constantly in need of recharging and home energy generation where large windmills are not preferred.
Inventor Nikola Tesla imagined the technology to transmit energy through thin air almost a century ago, but experimental attempts at the feat have so far resulted in cumbersome devices that only work over very small distances. But now, Duke University researchers have demonstrated the feasibility of wireless power transfer using low-frequency magnetic fields over distances much larger than the size of the transmitter and receiver.
A breakthrough technique for super-resolution 3D medical imaging of living cells has been developed by researchers at Swinburne University of Technology. The new technique potentially could aid in minimally-invasive surgery and the early detection of cancer.
With its original publication, the Dekker Encyclopedia of Nanoscience and Nanotechnology immediately became the reference against which all other nano references are measured. Continuing to cover the field as no other resource, the Third Edition describes the fundamentals and advancements of nano-materials, -structures, -devices, and -systems with a broad range of applications to assist readers in mastering the biological, engineering, physical, and technological aspects.
Researchers have developed a nanocarrier with the capability of sustained release for ocular indications. Specifically, the developed nanocarrier demonstrated sustained efficacy and proved to be well tolerated in a diseased nonhuman primate model, making it a prime sustained-release nanomedicine candidate for glaucoma therapy.
A new article presents commonly used models for biological membranes and highlights several techniques that can be employed to investigate the nonspecific interactions between engineered nanoparticles and model cell membranes.
New work opens up the possibility of determining the detailed topology of H-bonded networks at water/solid interfaces with atomic precision, which is only possible through theoretical simulations in the past.
