Solution-processed semiconductor and dielectric materials are attractive for satellite technology due to their light-weight, low-voltage operation, and mechanical robustness, but their response to ionizing radiation environments is not well understood.
Solar water splitting converts solar energy into chemical fuels that can be easily stored and transported. Silicon is already used on a large scale for photovoltaics, but it is unstable in the electrolytes used for water oxidation.
The combined results of controlled synthesis, ab-initio molecular-dynamics liquid-quench simulations, thorough structure and property characterization, and accurate density-functional calculations helped identify four major components that govern the electrical, optical, thermal, and mechanical properties of prototype In-based AOSs: (i) deposition temperature; (ii) oxygen stoichiometry; (iii) c
Among all Transparent conducting oxides, Zinc-Indium-Tin Oxides are known for their good chemical stability, smooth surfaces and most importantly, high electrical conductivity. Having access to fundamental information like kinetics parameters is extremely important for processing and fabrication of these materials.
Anisotropic gold nanoparticles have been shown to possess desirable plasmonic and optical properties at the single particle level, but ensemble averaged measurements are compromised by the as-synthesized polydispersity in nanoparticle size and shape.
Multimetallic nanoparticles are useful in many fields, yet there are no effective strategies for synthesizing libraries of such structures with systematic compositional tunability.
Restacked films of exfoliated 2D nanosheets can function as massive nanofluidic channel arrays. Recent research shows that cutting such membranes into asymmetric shapes leads to ionic current rectification.
Optical properties of layered materials can be controlled manipulating the discrete number of atomically-thin two-dimensional crystal layers. Unique amongst the layered transition metal dichalcogenides, ReS2 has optical emission that is linearly polarized and proportional to layer number.
Northwestern University with the Chicago Children’s Museum in prototyping and formative evaluation of the new permanent exhibit, Tinkering Lab, which focuses on the self-guided exploration of materials for K-8 students.
To increase awareness, promote international collaboration, and broaden participation from traditionally underrepresented groups in the NSF-MRSEC program, an NSF-MRSEC booth was featured at the XXV International Materials Research Congress in Cancun, Mexico.
