The refractive index of silicone oil (ne = 1.40) is close to that of living cells or cultured tissue slices (ne = 1.38), enabling super resolution imaging of internal cellular structures at
tens of micrometers in depth with minimal spherical aberration.
Thanks to the extraordinary light absorption capability of the plastics, the active plastics layer is extremely thin - only a few tenth
of micrometer thick, i.e. less than 1/1000 of silicon cell.
To produce miniscule rings?tens
of micrometers in diameter?that guide and enhance light with ultralow loss, the team used silicon nitride, a glass - like material they have perfected specifically for this purpose.
Five years ago, a team led by Jeffrey Cleland of the biotech firm Genentech in San Francisco set out to simplify the procedure with microspheres, plastic balls just a few tens
of micrometers across that slowly release drugs as they dissolve inside muscle or other tissue.
A paper in Science Advances by Rice engineers Ashok Veeraraghavan, Jacob Robinson, Richard Baraniuk and their labs describes a wide - field microscope thinner than a credit card, small enough to sit on a fingertip and
capable of micrometer resolution over a volume of several cubic millimeters.
In addition, the researchers integrated the sensor into a microfluidic system
made of micrometer - sized channels containing nanoliters of liquids.
This enabled researchers to generate serial images that went deeper into the tissue as each top slice was removed — to follow fine neural processes for
hundreds of micrometers.
We only use less than a couple
of micrometers for everything else,» says UW - Madison electrical and computer engineering professor Zhenqiang «Jack» Mas.
The most important of these are two layers of tungsten oxide and nickel oxide, both about a
third of a micrometer thick.
Nanowires are very small — about 2 micrometers high (1 micrometer is a thousandth of a millimetre) and 10 - 500 nanometers in diameter (1 nanometer is a
thousandth of a micrometer).
Ph.D. student Aaron O'Connell was able to induce and measure quantum effects in the
motion of a micrometer - sized mechanical oscillator.
With a diameter in the
region of a micrometer and a genome incorporating more than 1,100 genes, these giant viruses, which infect amoebas of the Acanthamoeba genus, had already largely encroached on areas previously thought to be the exclusive domain of bacteria.
To prove the «skin cloak» works, they built one to hide a
landscape of micrometer - sized hills and valley and make it appear mirror flat.
The infrared radiation from these regions revealed copious
amounts of micrometer - sized crystalline grains.
Working with the IIS Applied Microfluidic Laboratory of Professor Teruo Fujii, they developed a platform to generate a
myriad of micrometer - sized droplets containing random concentrations of reagents and then sandwich a single layer of them between glass slides.
Simple sensors can tell a machine whether it is in contact with something, but detectors that also sense texture tend either to be too complicated and delicate for commercial use or lack the spatial resolution needed to detect details
dozens of micrometers across.
Pierre Wiltzius, a physicist at the University of Illinois, Urbana - Champaign, says that if researchers can further reduce the voltages and increase the temperature range, the effect might be useful in a wide
variety of micrometer - scale technologies.
They found that their conductive paste
consisting of micrometer - sized silver (Ag) flakes, fluorine rubber, fluorine surfactant — commonly known as a substance that reduces surface tension in liquid — and organic solvent to dissolve the fluorine rubber markedly outperformed the elastic conductor they had previously developed in 2015.
The device can capture depths as small as a
fraction of a micrometer, allowing printed letters, like these ones, to show up as 3D.
To concentrate the energy of laser light to an even finer area, the team patterned aluminum dots of various sizes, from tens
of micrometers down to 30 nanometers, across the surface of silicon, silicon germanium alloy, gallium arsenide, gallium nitride, and sapphire.
When there's a
snowfall of a micrometer or more, the snow stays on the road until hundreds of Michiganders have driven across it and forced it into dingy snowbanks on the shoulders of the asphalt.
By employing the same physical - chemical process that transports water in trees, the researchers say they have solved a problem conventional production methods encounter: getting enough electrolyte into the huge
number of micrometer - sized pores in battery electrodes.
A geoscientist whose own research uses meteorites to trace the history of the solar system, Kita is director of the Wisconsin Secondary Ion Mass Spectrometer Laboratory, the National Science Foundation — funded facility that houses the $ 6 million instrument, the first of its kind in the world
capable of micrometer - scale geochemical measurements.
Saturn's E ring,
made of micrometer - sized particles, is suspected of having been created by ice geysers on Enceladus.
The scientists synthesized the sponges by a chemical vapor deposition (CVD) process during which the CNTs (multi-walled nanotubes with diameters in the range of 30 to 50nm and lengths of tens to
hundreds of micrometers,) self - assembled into a porous, interconnected, three - dimensional framework.
When the target is
tens of micrometers thick, such as in hESC colonies, there is a large z - range of equally good focus, and hence the autofocus is not recommended.
Just as a song's bass thumps in your chest at a concert, Mary's lamb caused minute vibrations — just
tenths of a micrometer — in the chip bag.
They drift in Earth's atmosphere from the stratosphere to the surface and range in size from a few nanometers — less than the width of the smallest viruses — to several several tens
of micrometers — about the diameter of human hair.
And they come in very different sizes, ranging from a few nanometers to tens
of micrometers.
