Stanford engineers create solar panel that can generate electricity at night

Stanford engineers create solar panel that can generate electricity at night

Good News Notes: “A team of engineers at Stanford University have developed a solar cell that can generate some electricity at night. The research comes at a moment when the number of solar jobsand residential installations are rising. While standard solar panels can provide electricity during the day, this device can serve as a “continuous renewable power source for both day- and nighttime,”…

Las lágrimas energéticas

Científicos irlandeses descubrieron que una sustancia, conocida como lisozima, presente en la baba y en las lágrimas de los seres humanos, es capaz de servir como fuente de electricidad. Los resultados de su estudio fueron publicados en la revista Applied Physics Letters. Hay leyendas que afirman que las lágrimas son un ingrediente básico para muchas pociones mágicas ya que estas contienen una enorme potencia curativa. Es poco probable que algún científico quiera comprobar estas aseveraciones dado que la composición de las lágrimas es bien conocida. Pero es bien sabido que no hay nada extraordinario en las lágrimas: solo agua, material inorgánico y varias proteínas.

UCF Scientist Creates Most Efficient Quantum Cascade Laser Ever

UCF Scientist Creates Most Efficient Quantum Cascade Laser Ever

A Team of UCF researchers has produced the most efficient quantum cascade laser ever designed – and done it in a way that makes the lasers easier to manufacture.

Quantum cascade lasers, or QCLs, are tiny – smaller than a grain of rice– but they pack a punch. Compared to traditional lasers, QCLs offer higher power output and can be tuned to a wide range of infrared wavelengths. They can also be…

Tailored Probes for Atomic Force Microscopes

Tailored Probes for Atomic Force Microscopes

Atomic force microscopes make the nanostructure of surfaces visible. Their probes scan the investigation material with finest measurement needles. KIT has now succeeded in adapting these needles to the application. For any measurement task, e.g. for various biological samples, a suitable measurement needle can be produced. For production, 3D laser lithography, i.e. a 3D printer of structures in…

New Metamaterials Can Change Properties with a Flick of a Light-switch

New Metamaterials Can Change Properties with a Flick of a Light-switch

Invisibility cloaks have less to do with magic than with metamaterials. These human-engineered materials have properties that don’t occur in nature, allowing them to bend and manipulate light in weird ways. For example, some of these materialscan channel light around an object so that it appears invisible at a certain wavelength. These materials are also useful in applications such as smaller,…

Graphene key to high-density, energy-efficient memory chips, Stanford engineers say 

Only an atom thick, graphene is a key ingredient in three Stanford projects to create data storage technologies that use nanomaterials other than standard silicon.

The memory chips in phones, laptops and other electronic devices need to be small, fast and draw as little power as possible. For years, silicon chips have delivered on that promise.

But to dramatically extend the battery life of…
