Laser-induced graphene is what researchers at Rice University call their new material. They created flexible, patterned sheets of multilayer graphene from a cheap polymer (polyimide) by burning it with a computer-controlled laser.
The growth process of platinum nanocubes was monitored directly by Berkeley Lab researchers for the first time.
The growth process of platinum nanocubes was monitored directly by Berkeley Lab researchers for the first time. The observations of how facets form and develop on platinum nanocubes point the way towards more sophisticated and effective nanocrystal design and reveal that a nearly 150 year-old scientific law describing crystal growth breaks down at the nanoscale.
Having started off in the electronics industry and material sciences, nanotechnology is now increasingly taking a foothold in our daily lives. One topic currently under discussion is the use of nanomaterials in food, food packaging and kitchen utensils. To explore the opportunities and risks and for the purposes of monitoring labelling requirements, it is necessary to develop methods for the detection and characterization of nanomaterials in the food sector.
Biomimetic Engineering: "Learning from nature" - this fundamental idea has been followed by scientists, inventors and engineers for a long time. Within 3.8 billion years of evolution nature has developed a huge number of solutions, which could be used for solving problems in various fields of engineering. The implementation of ideas from nature into engineering in a creative way is called ‘biomimetics' [1,2].
Every great structure, from the Empire State Building to the Golden Gate Bridge, depends on specific mechanical properties to remain strong and reliable. Rigidity-a material's stiffness-is of particular importance for maintaining the robust functionality of everything from colossal edifices to the tiniest of nanoscale structures. In biological nanostructures, like DNA networks, it has been difficult to measure this stiffness, which is essential to their properties and functions.
EMBL image: As spring arrives, flowers seem to bloom everywhere - even under the microscopes at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany. But the ‘flowers' in this picture actually help an animal, not a plant, to pass on its genes. The image, which has been false-colored for artistic effect, shows a slice through the tails of mouse sperm. Each ‘flower' is the tail that a sperm cell wags to swim.
EMBL: In this video (click here), a protein called myomesin does its impression of Mr. Fantastic, the leader of the Fantastic Four of comic book fame, who performed incredible feats by stretching his body.
FEI and Oregon Health & Science University (OHSU) announced a partnership to create the OHSU/FEI Living Lab for Cell Biology that will provide researchers with several state-of-the-art electron microscopes to advance the understanding and treatment of complex diseases such as cancer and AIDS.
The OHSU/FEI Living Lab will be equipped with a variety of high-performance equipment including a Titan Krios transmission electron microscope (TEM) and a Helios NanoLab DualBeam.
Bacteria like salmonellae infect their host cells by needle-shaped extensions which they create in large numbers during an attack. A group of Vienna-based scientists headed by Thomas Marlovits employed recently developed methods of cryo-electron microscopy and have been able to clarify the structure of this infection apparatus on the near-atomic scale.
