6:31 PM | Fundamental chemistry findings could help extend Moore's Law
In a bid to continue decreasing transistor size while increasing computation and energy efficiency, chip-maker Intel has partnered with researchers from Lawrence Berkeley National Lab to design an entirely new kind of resist. Results could be easily incorporated by companies that make resist, and find their way into manufacturing lines as early as 2017.

5:58 PM | 3-D boron nitride nanostructure could benefit nanoelectronics, gas storage
A three-dimensional porous nanostructure would have a balance of strength, toughness and ability to transfer heat that could benefit nanoelectronics, gas storage and composite materials that perform multiple functions.

4:18 PM | Dynode Dawdling Lab Book 2014_07_14
Summary:The photomultiplier tube on the NaI detector doesn't seem to be doing quite what it should.  There's a generally held belief, (when I say generally held belief, read, "a professor told me"), that the count rates aren't high enough.  Last week, the case of the tube was arcing to my hand making nice little static shock looking flashes of light.  Consequently, I spent today doing research on the three most likely PMT tubes that are housed within the detector.  Since the […]

3:41 PM | Bubbles Help Your Pancakes Gel
My family was big on Sunday morning breakfasts growing up, and pancakes made a frequent appearance. When I was old enough to learn how to make them, my father shared one common piece of advice: wait to flip the pancakes until bubbles start to burst on the top of the batter and hold their shape.Image Credit: Hedvig on Flickr I always thought the most interesting part of this instruction was waiting for the shape to hold. That precise moment indicates the pancake is in the state of changing […]

2:32 PM | Directly visualizing hydrogen bonds
Using a newly developed, ultrafast femtosecond infrared light source, chemists have been able to directly visualize the coordinated vibrations between hydrogen-bonded molecules - the first time this sort of chemical interaction, which is found in nature everywhere at the molecular level, has been directly visualized.

2:27 PM | Thermoelectric nanomaterials for future green tech devices
Thermoelectric devices, which convert heat to electricity and vice versa, can harness that wasted heat, and possibly provide the green tech energy efficiency that's needed for a sustainable future. A new study shows how porous substances can act as thermoelectric materials - pointing the way for engineering the use of such materials in thermoelectric devices of the future.

1:21 PM | Crepuscular Rays
Crepuscular Rays are rays of sunlight which appear to radiate from the point in the sky where the Sun is located. Most of us have seen these awesome columns of sunlit air as they stream through gaps in clouds, or sometimes between other objects such as trees or buildings.  The cool ‘columns of sunlight’ effect […]

12:54 PM | Researchers develop an extremely simple procedure to obtain nanosized graphenes (w/video)
This method is based on the reactivity of a group of molecules named arynes, which can act as 'molecular glue' to paste graphene fragments together. The clover-shaped nanographenes obtained in this research were deposited on ultrathin insulating films, and imaged with atomic resolution by atomic force microscopy.

12:45 PM | Novel method for growing high-quality oxide thin films on a glass substrate
Researchers succeeded in growing thin film crystals consisting of highly oriented crystal grains, which were as large as a few micrometers or more, by coating a glass substrate with oxide sheets of about one nanometer in thickness, called oxide nanosheets, and using these nanocrystals as seed crystals in solid phase crystallization.

10:43 AM | Fair Play
It was such such an refreshing site to see Dilma Rousseff and Angela Merkel in the VIP box of World Cup final! No, I'm not a fan of either of them. But at least they brought some balance to the otherwise hopelessly male dominant gala fest of power, money and muscle! From players, to coaches, support stuffs, FIFA officials, even the vast majority of reporters and photographers....it was such an

8:31 AM | Science journalists pen Copenhagen Declaration on nanotechnology
The science debate of the European Science Journalists EUSJA revealed many severe misunderstandings and a profound lack of knowledge about nanotechnology, two decades after the topic first emerged. More detailed information and more dialogue is necessary, in particular a broader array of inclusive, participative and collaborative formats, above all in the early phases of research.

8:07 AM | A Swiss cross made of 20 atoms
The manipulation of atoms has reached a new level: Physicists were able to place 20 single atoms on a fully insulated surface at room temperature to form the smallest 'Swiss cross', thus taking a big step towards next generation atomic-scale storage devices.

Blackest is the new black: Scientists have developed a material so dark that you can’t see it… A British company has produced a “strange, alien” material so black that it absorbs all but 0.035 per cent of visual light, setting a new world record. To stare at the “super black” coating made of carbon nanotubes [...]

7:34 AM | Photorealistic plasmonic printing with aluminum nanostructures
Aluminum has gained interest in the field of nanoplasmonics not only because it is abundant and costs a fraction of gold or silver, but also because it allows field-enhancement effects into the ultraviolet. However, it has broader resonances than silver and gold, and forms an oxide layer. Both these effects are undesirable in applications such as biosensing, in which signal strengths are reduced in the presence of resistive losses and oxide barriers. However, color printing based on the plasmon […]
