Researchers at Stanford have developed a new technique to pack molecules closer together in organic semiconductors, more than doubling the speed of electrical charge movement. This breakthrough enables faster electronics for foldable devices and solar-powered energy harvesting.
Researchers developed an economical method to detect groundwater in semi-arid hard rock areas by analyzing electrical conductivity logs. The approach revealed differences in subterranean rock fissures and correlated with regions of underground water. This technique may be useful for identifying the most abundant sources of groundwater.
Researchers at MIT have found a way to manipulate the electrical and thermal properties of materials by changing external conditions such as temperature. The technique can change electrical conductivity by over 100 times and heat conductivity by threefold, making it suitable for various applications including electronic circuitry and t...
The new study creates a detailed image of the Yellowstone plume's electrical conductivity, showing it dips more gently and extends farther east-west. The geoelectric image suggests the plume may be enveloped by a broader sheath of partly molten rock and liquids.
Scientists at Lawrence Berkeley National Laboratory found that introducing oxygen impurities into highly mismatched alloys can substantially enhance thermoelectric performance. This approach allows for the creation of materials with high thermopower and electric conductivity, promising a breakthrough in green energy production.
Researchers at Lawrence Livermore National Laboratory discovered a series of pressure-induced structural and electronic transitions in molten sodium, leading to a threefold drop in electrical conductivity. This unexpected behavior challenges traditional expectations of metals under extreme conditions.
Physicists simulated gases in optical lattices to study the behavior of electrons in materials. They found that electron blocking occurs even when the lattice would normally be a good conductor, and interference effects form natural fractal patterns.
Researchers at the University of Pennsylvania have created a method to mix single-walled carbon nanotubes into polymers for enhanced strength, conductivity, and thermal stability. The technique uses coagulation to disperse nanotubes evenly, achieving significant improvements in material properties.
A new approach suggests using nitrification inhibitors to reduce nitrate leaching to groundwater. Researchers developed management zones based on soil properties and crop yield maps, showing increased yield in wet seasons without affecting grain yield or nitrate leaching in dry seasons.
Research reveals DNA's chaotic movements limit its electrical conductivity, making it challenging for scientists to develop new molecular microelectronics. A fixed double-helix structure would improve DNA's ability to initiate reactions through charge transfer.
Researchers at UC Irvine have created a new method for producing metal nanowires with desired conductivity, strength, and length. The step-edge decoration process allows for the growth of long, uniform wires needed for emerging nanotechnologies like diodes and transistors.
The Sandia chuck uses a thin layer of helium gas to cool silicon wafers, utilizing electrostatic attraction to seal the wafer to a bottom plate. The device features a patterned silicon wafer with tiny islands that support the wafer and allow for rapid clamping and release.
Researchers at Johns Hopkins University Applied Physics Laboratory find auroras occur predominantly in darkness, between sunset and midnight, and mainly during spring, winter, and fall months. Their study provides strong support for an existing theory explaining aurora formation, which correlates to ionospheric electrical conductivity.
