Sentences with word «microdroplet»

However, the most striking observation came while running a control experiment in which they replaced the reducing agent — which ordinarily releases the gold particles — with microdroplets of water.

Indeed, the team observed that gold nanoparticle grew over 100,000 times faster in microdroplets.

It's still unclear why water microdroplets are able to replace a reducing agent in this reaction.

Xiangjia Li, a PhD student on Chen's team and co-first author of the study, says one example of high - performance microdroplet manipulation could lead to more efficient blood analyses for patients.

One possibility is that transforming the water into microdroplets greatly increases its surface area, creating the opportunity for a strong electric field to form at the air - water interface, which may promote the formation of gold nanoparticles and nanowires.

And on the sea floor, animals that strain food from the water, including tube worms, clams, mussels and barnacles, could also be exposed to oil microdroplets in the water or to residues buried in the sediment.

A robotic gripper could move to different stations and dispense microdroplets of blood that are then evenly mixed with different chemicals for various tests.

The key ingredient in «thubber» is a suspension of non-toxic, liquid metal microdroplets.

Whereas fog is made of ready - made microdroplets floating in the air, dew appears following the cooling of a substrate below air temperature.

The WSU research team used a 3 - D printing method to create foglike microdroplets that contain nanoparticles of silver and to deposit them at specific locations.

We work across disciplines and use a variety of techniques including microfluidics, standard microscopies (electron, optical, fluorescence, confocal), spectroscopies (fluorescence, UV, CD), scattering techniques (X-ray, light), protein expression and characterization and cell - free gene expression to investigate the utility of coacervate microdroplets as robust reaction compartments and cellular mimics.

Kennel cough is common in dogs and is spread through microdroplets of saliva and nasal discharge (such as a sneeze or cough).

In addition, the material is capable of «microdroplet manipulation,» or the transfer of miniature volumes of liquid.

But if you turn the water in that beaker into microdroplets, you will get about 3,000 square meters of surface area — about the size of half a football field,» Zare said.

Their inspiration: Drop - Seq, a single - cell RNA - seq (scRNAseq) technique that encapsulates single cells together with DNA barcoded - beads in microdroplets to greatly accelerate expression profiling experiments and reduce cost.

The surprise finding means that pure water microdroplets can serve as microreactors for the production of gold nanostructures.

Another negative mechanism: Microdroplets of oil dispersed in the water might set off a feeding frenzy of microbes able to dine on the hydrocarbons, further reducing oxygen levels.

«Salvinia effect» also has potential for liquid - handling technology that executes «microdroplet manipulation» — a breakthrough where the adhesion of liquid to a robotic arm can be tuned accordingly and result in non-loss transfer for very tiny amounts of liquid.

How large is a microdroplet?

From previous experiments, the scientists knew that some chemical reactions proceed much faster in microdroplets than in larger solution volumes.

«It is like squeezing a perfume bottle and out spritzes a mist of microdroplets,» Zare said.

Both structures were formed using a novel redox reaction involving water microdroplets.

Microdroplets produced in this way in real clouds could merge until they are big enough to fall as a raindrop, or be swept into an updraft and then create microdroplets of their own.

But if you turn the water in that beaker into microdroplets, you will get about 3,000 square meters of surface area - about the size of half a football field,» Zare said.
