Substrate defects key to growth of 2D materials
14-May-2019
Creating two-dimentional materials large enough to use in electronics is a challenge despite huge effort but now, Penn State researchers have discovered a method for improving the quality of one class of 2D materials, with potential to achieve wafer-scale growth in the future. The field of 2D ...
New sensor detects rare metals used in smartphones
25-Apr-2019
A more efficient and cost-effective way to detect lanthanides, the rare earth metals used in smartphones and other technologies, could be possible with a new protein-based sensor that changes its fluorescence when it binds to these metals. A team of researchers from Penn State developed the ...
Tiny fibers create unseen plastic pollution
18-Feb-2019
While the polyester leisure suit was a 1970s mistake, polyester and other synthetic fibers like nylon are still around and are a major contributor to the microplastics load in the environment, according to a Penn State materials scientist, who suggests switching to biosynthetic fibers to solve ...
Antireflection coating makes plastic invisible
31-Jan-2019
Antireflection (AR) coatings on plastics have a multitude of practical applications, including glare reduction on eyeglasses, computer monitors and the display on your smart-phone when outdoors. Now, researchers at Penn State have developed an AR coating that improves on existing coatings to the ...
Bacterial protein could help find materials for your next smartphone
21-Dec-2018
A newly discovered protein could help detect, target, and collect from the environment the rare-earth metals used in smartphones. Two new studies by researchers at Penn State describe the protein, which is 100 million times better at binding to lanthanides--the rare-earth metals used in ...
Sintering atomically thin materials with ceramics now possible
03-Jul-2018
For the first time, researchers have created a nanocomposite of ceramics and a two-dimensional material, opening the door for new designs of nanocomposites with such applications as solid-state batteries, thermoelectrics, varistors, catalysts, chemical sensors and much more. Sintering uses high ...
Capturing light in a waveguide array
07-Jun-2018
Cheaper and more efficient photonic devices, such as lasers, optical fibers, and other light sources may be possible with confined light that is unaffected by imperfections in the material that confines it, according to new research. A team of physicists from Penn State, the University of ...
Flexible, highly efficient multimodal energy harvesting
23-May-2018
A 10-fold increase in the ability to harvest mechanical and thermal energy over standard piezoelectric composites may be possible using a piezoelectric ceramic foam supported by a flexible polymer support, according to Penn State researchers. In the search for ways to harvest small amounts of ...
A simple method etches patterns at the atomic scale
27-Apr-2018
A precise, chemical-free method for etching nanoscale features on silicon wafers has been developed by a team from Penn State and Southwest Jiaotong University and Tsinghua University in China. In standard lithography, a photosensitive film is deposited on a silicon wafer and a pattern called a ...
New sodium-ion electrolyte may find use in solid-state batteries
11-Apr-2018
A newly discovered structure of a sodium-based material allows the materials to be used as an electrolyte in solid-state batteries, according to researchers from Penn State and Pacific Northwest National Laboratory (PNNL). The team is fine-tuning the material using an iterative design approach ...
