Image-dipole distortionsjqi fellow Edo Waks and his colleagues have performed nanoscopic mappings of the electromagnetic field profile around silver nanowires by positioning quantum dots (the emitter) nearby.
namely that an"image dipole"induced in the surface of the nanowire was distorting knowledge of the quantum dot's true position.
This uncertainty in the position of the quantum dot translates directly into a distortion of the electromagnetic field measurement of the object.
The distortion results from the fact that an electric charge positioned near a metallic surface will produce just such an electric field
but it does have a net electrical dipole, a slight displacement of positive and negative charge within the dot.
the wire develops an"image"electrical dipole whose emission can interfere with the dot's own emission.
the presence of light coming from the"image dipole"can interfere with light coming directly from the dot.
The JQI experiment successfully measured the image-dipole effect and properly showed that it can be corrected under appropriate circumstances.
The resulting work provides a more accurate map of the electromagnetic fields surrounding the nanowire. The JQI scientists published their results in the journal Nature Communications.
or high-dielectric structure image-dipole effects can cause errors. Because these effects can distort the measurement of the nano-emitter's position they are important to consider for any type of super-resolved imaging that performs spatial mapping.""

#Drexel Univ. materials research could unlock potential of lithium-sulfur batteries Drexel researchers, along with colleagues at Aix-Marseille University in France, have discovered a high performance cathode material with great promise for use in next generation lithium-sulfur batteries that could one day be used to power
mobile devices and electric cars. Lithium-sulfur batteries have recently become one of the hottest topics in the field of energy storage devices due to their high energy density
--which is about four times higher than that of lithium-ion batteries currently used in mobile devices.
One of the major challenges for the practical application of lithium-sulfur batteries is to find cathode materials that demonstrate long-term stability.
An international research collaboration led by Drexel's Yury Gogotsi, Phd, Distinguished University and Trustee Chair professor in the College of Engineering and director of its Nanomaterials Research Group, has created a two-dimensional carbon/sulfur nanolaminate that could be a viable candidate for use as a lithium-sulfur
Distinguished professor in Drexel's Department of Materials science & Engineering, has been used as the basis for much of Drexel's materials research intended to find better materials for batteries.
This structure is key to their potential for being used as electrode materials for lithium-sulfur batteries.
Currently, sulfur infiltrated carbon nanomaterials have demonstrated to be the most promising cathode materials for Li-S batteries.
This may have a significant impact on increasing the life-span of next generation batteries.""We have enough evidence to show that that the electrochemical etching can be a powerful method to selectively extract the'M'elements from the MAX phases,
Gogotsi estimates that odds are with the MAX phase's new"AX"progeny becoming the materials that find use in next-generation electrical storage devices."

#Researchers synthesize new thin-film material for use in fuel cells: Article in the journal APL Materials shows how to grow Bi2pt2o7 pyrochlore, potentially a more effective cathode for future fuel cells Abstract:
Researchers from Cornell University have synthesized a new thin-film catalyst for use in fuel cells. In a paper published March 10 in the journal APL Materials, from AIP Publishing, the team reports the first-ever epitaxial thin-film growth of Bi2pt2o7 pyrochlore,
which could act as a more effective cathode--a fundamental electrode component of fuel cells from which positive current flows through an external circuit delivering electric power."
"Up to now, research on oxygen catalysts in thin film form for clean energy applications has been focused on the perovskite-structured oxides
and their structural derivatives,"said lead researcher Araceli Gutierrez-Llorente.""The much less studied cubic pyrochlore structure is an appealing alternative to perovskites for such applications as fuel cell cathodes."
"The pyrochlore in question--Bi2pt2o7--has previously been synthesized successfully as a nanocrystalline powder. Epitaxial thin films can actually act as more efficient fuel cell catalysts than nanocrystalline powder,
but growing Bi2pt2o7 directly as a film requires oxidizing the platinum metal--a challenging step.
The team used pulsed laser deposition to co-deposit epitaxial? -Bi2o3 and disordered platinum. Annealing the film in air forced the platinum to oxidize
thought to be one of the most promising oxide catalysts for fuel cell applications, "said Gutierrez-Llorente.
The cathode of a solid oxide fuel cell electrochemically reduces oxygen. Bi2pto7's oxygen-deficient structure makes it an ideal catalyst for the process.
Synthesizing the material as a thin film instead of as a bulk powder opens up new possibilities for fuel cell technology."

a development that could mean faster charging time and longer battery life in electric vehicles and portable electronics.
As a novel energy storage device, supercapacitors have attracted substantial attention in recent years due to their ultra-high charge
while supercapacitors have the potential to charge faster and last longer than conventional batteries, they also need to be much larger in size
and mass in order to hold the same electric energy as batteries. Thus, many scientists are working to develop green, lightweight, low-cost supercapacitors with high performance.
In energy storage devices, storing an electrical charge is called"energy density,"a distinction from"power density, "which refers to how quickly energy is delivered.
Conventional capacitors have high power density but low energy density, which means they can quickly charge
and discharge and release a burst of electric power in a short time, but they can't hold a large amount of electric charges.
Conventional batteries on the other hand, are the opposite. They have high energy density or can store a lot of electric energy, but can take hours to charge and discharge.
Supercapacitors are a bridge between conventional capacitors and batteries, combining the advantageous properties of high power, high energy density and low internal resistance,
which may replace batteries as a fast, reliable and potentially safer power source for electric and portable electronic devices in future, said Singh.
In supercapacitors, high capacitance, or the ability to store an electrical charge, is critical to achieve higher energy density.
Meanwhile, to achieve a higher power density it is critical to have a large electrochemically accessible surface area, high electrical conductivity and short ion diffusion pathways.
and transporting ions through another material at the interface between electrode and electrolyte. Larger redox reaction surfaces are essential for achieving a higher power density for supercapacitors."

Simple design mimics pumping mechanism of life-sustaining proteins found in living cells The new machine mimics the pumping mechanism of life-sustaining proteins that move small molecules around living cells to metabolize and store energy
For its food, the artificial pump draws power from chemical reactions, driving molecules step-by-step from a low energy state to a high-energy state--far away from equilibrium.
"Our molecular pump is radical chemistry--an ingenious way of transferring energy from molecule to molecule,
The artificial pump is able to syphon off some of the energy that changes hands during a chemical reaction
but the researchers believe it won't be long before they can extend its operation to tens of rings and store more energy.
"This is non-equilibrium chemistry, moving molecules far away from their minimum energy state, which is essential to life,
"Ultimately, they intend to use the energy stored in their pump to power artificial muscles and other molecular machines.
They are used also in other industries to manufacture fuel cells, batteries, filters and light-emitting screens."
"Currently, the most common nanofiber manufacturing technique--electrospinning--uses high-voltage electricity and specially designed equipment to produce the polymer strings.

"Ionics, ion-based data processing and energy conversion, is the electronics of the future, "says Jennifer Rupp, a professor of Electrochemical Materials at ETH Zurich,
for example, in lambda sensors of automotive catalytic converters and solid oxide fuel cells. The ETH professor is convinced that the industrial importance of these materials will even further increase-for example, in gas sensors, new classes of data storage and computer circuits,
and in the conversion of chemical energy into electrical energy and vice versa. One of the most important research questions in Rupp's field currently is how to optimise these materials,
Shi attached microelectrodes to small pieces of these membranes to create tiny components that can be used to generate electricity from hydrogen or organic compounds and from oxygen in the air.
"Even in earlier experiments, scientists noticed that power generation in micro solid oxide fuel cells varies greatly depending on the structure of such cells.
This supports the development of future gas sensors, ion-based data storage and micro energy converters, such as fuel cells-and potentially a range of other as yet unknown applications in the promising field of ionics.##

#Sweeping lasers snap together nanoscale geometric grids: New technique creates multilayered, self-assembled grids with fully customizable shapes and compositions Down at the nanoscale,
where objects span just billionths of a meter, the size and shape of a material can often have surprising and powerful electronic and optical effects.
Now, scientists at the U s. Department of energy's Brookhaven National Laboratory have developed a new technique to rapidly create nano-structured grids for functional materials with unprecedented versatility."

and overlap shapes the grid. We then apply the functional materials after each layer forms.
"For example, a single layer of platinum nanowires conducts electricity in only one direction, but a two-layer mesh conducts uniformly in all directions."
