Super-resolution atom-by-atom laser machining method allows for making nanoscale devices

March 11, 2014


Australian researchers have discovered how to use laser light to pick apart a substance atom by atom, allowing for creating new nanoscale diamond devices.

“Lasers are known to be very precise at cutting and drilling materials on a small scale — less than the width of a human hair, in fact — but on the atomic scale they have notoriously poor resolution,” says lead researcher Associate Professorread more

Super-resolution electron microscopy of soft materials like biomaterials

Breakthrough technique allows for noninvasive nanoscale imaging with electron beams, bypassing optical microscopy limitations
June 5, 2015

CLAIRE image-ft

Soft matter encompasses a broad swath of materials, including liquids, polymers, gels, foam and — most importantly — biomolecules. At the heart of soft materials, governing their overall properties and capabilities, are the interactions of nano-sized components.

Observing the dynamics behind these interactions is critical to understanding key biological processes, such as protein crystallization and metabolism, and could help accelerate the development of important new technologies, such as artificial… read more

Super-resolution microscopy takes on a third dimension

February 3, 2009

Howard Hughes Medical Institute scientists have developed a new interferometry-based imaging technology that produces the best three-dimensional resolution ever seen with an optical microscope, pinpointing fluorescent labels in their images to within 10-20 nanometers.

Super-Resolution X-ray Microscopy unveils the buried secrets of the nanoworld

July 21, 2008

A novel super-resolution X-ray microscope developed by Paul Scherrer Institut and EPFL researchers combines the high penetration power of x-rays with high spatial resolution with raster scanning, making it possible to non-destructively view the detailed interior composition of sub-hundred-nanometer semiconductor devices or biological samples without requiring a vacuum.

Super-sensors To Discover What Happened In First Trillionth Of A Second After Big Bang

May 5, 2009

Super-sensitive microwave detectors built at the National Institute of Standards and Technology (NIST) will look for faint polarization signals from primordial gravitational waves in the cosmic microwave background next year.

If found, these waves would be the clearest evidence yet in support of the inflation theory, which suggests that all of the currently observable universe expanded rapidly from a subatomic volume, leaving in its wake the telltale cosmic background… read more

Super-stretchy skin-like sensor uses nanotube springs

October 25, 2011

Super-Stretchy Skin-Like Sensor

Stanford University’s Zhenan Bao, associate professor of chemical engineering, has developed a transparent film of single-walled carbon nanotubes that act as tiny springs that accurately measure the force applied.

The sensors could be used in making touch-sensitive prosthetic limbs or robots, in touch screens on computers, or for various medical applications such as pressure-sensitive bandages.

“This sensor can register pressure ranging from a firm pinch between your thumb… read more

Super-stretchy, self-healing material could lead to artificial muscle

Stanford researchers have developed a new material that can stretch to 100 times its original length by exposing it to an electric field, and even repair itself if punctured, making it potentially useful as an artificial muscle.

Artificial muscles currently have applications in some consumer technology and robotics, but small holes or defects in the materials currently used make them less resilient, and they can’t self-repair if punctured or scratched,… read more

‘Super-TB’ Created by Scientists

January 13, 2004

A virulent form of tuberculosis was created in a laboratory by experts trying to alter its genetic structure. They disabled the collection of genes thought to give TB some of its virulence and expected to find a weakened form of TB as a result. Instead, the organism grew in virulence.

Computer scientist Hava Siegelmann of the Biologically Inspired Neural & Dynamical Systems (BINDS) Laboratory at the University of Massachusetts Amherst, an expert in neural networks, has taken Alan Turing’s work to its next logical step.

She is translating her 1993 discovery of what she has dubbed “Super-Turing” computation into an adaptable computational system that learns and evolves, using input from the environment in a way much more like our… read more

SuperAger brains yield new clues to their remarkable memories

SuperAgers, aged 80 and above — but with memories that are as sharp as those of healthy persons decades younger — have distinctly different looking brains than those of normal older people, according to new Northwestern Medicine research.

Understanding Superagers’ unique “brain signature” may enable scientists to decipher the genetic or molecular source and develop strategies to protect the memories of normal aging persons, as well as… read more

Superantibodies target diseases by entering cells

April 15, 2004

Superantibodies that can bind to targets within cells, rather than on their surface, could lead to a new range of treatments for diseases, InNexus Biotechnology of Vancouver claims.

Superantibodies could be used to target bacteria and viruses (including HIV) inside cells, for instance, or abnormal proteins that turn cells cancerous. In theory, they could do everything that the small molecules of most conventional drugs do, and more.

The… read more

Superbug genome sequenced

May 8, 2008

University of Bristol and Wellcome Trust Sanger Institute researchers have sequenced the genome of a newly emerging superbug commonly known as Steno.

The bacteria has strains that are resistant to all available antibiotics. It flourishes in moist environments, and can form a “biofilm” on hospital catheters or ventilation tubes that protects the bacteria and makes it difficult to sterilize equipment.

Having the genome should help researchers combat these… read more

Supercapacitor “battery” could lead to instant charging, long charge life

September 5, 2007

EEStor claims to have developed a car battery based on capacitors that can be charged quickly and is ready for large-scale production.

The patent specifies charge storage that is much higher than anything achieved in an academic lab: 52 kilowatt-hours in a 2,000 cubic inch capacitor array — more than 10 times the power density of standard lead-acid batteries.

Supercapacitors from ‘crumpled graphene’ could power flexible electronic devices

October 7, 2014

To form the crumpled graphene, a sheet of polymer material is stretched in both dimensions, then graphene paper is bonded to it. When the polymer is released in one direction, the graphene forms pleats, as shown in the bottom left image, taken with a scanning electron microscope (SEM). Then, when released in the other direction, it forms a chaotic crumpled pattern (top left). At top right, an SEM image shows the material in a partially crumpled state.

MIT researchers have found that crumpling a piece of graphene “paper” — a material formed by bonding together layers of the two-dimensional form of carbon — can yield new properties that could be useful for creating extremely stretchable supercapacitors to store energy for flexible electronic devices.

The finding is reported in the journal Scientific Reports (open access) by MIT’s Xuanhe Zhao, an assistant professor of mechanical engineering and civil and… read more

Supercentenarian Research Foundation Plans Tissue Sampling of Supercentenarians

September 5, 2006

The Los Angeles Gerontology Research Group has created a tax-exempt Supercentenarian Research Foundation to fund tissue sampling of all living Supercentenarians (persons 110 years or older) worldwide.

The aim of the Foundation is “to develop a rigorous, statistically significant database of the most important SNPs (Single Nucleotide Polymorphisms) of ‘gerontic’ (longevity) genes,” said Los Angeles Gerontology Research Group Co-founder L. Stephen Coles, M.D., Ph.D.… read more
