In-situ Crystallization and Morphological Evolution in Multicomponent Indium Oxide Thin Films

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.

Homogeneous Gold Nanostars

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.

Polyelemental Nanoparticle Libraries

Multimetallic nanoparticles are useful in many fields, yet there are no effective strategies for synthesizing libraries of such structures with systematic compositional tunability.

Kirigami Nanofluidics

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.

Anisotropic Polarized Emission from ReS2

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.

NSF-MRSEC Booth at International Materials Research Congress

Education

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.

Understanding Loops in Polymer Networks Results in an Improved Theory for Rubbery Materials

Research

MRSEC researchers have used newly developed loop counting methods to precisely measure the storage moduli and loop fractions of a range of rubbery gels. A new theory, called Real Elastic Network Theory (RENT) was derived that describes how loop defects affect bulk elasticity.

Controlled Fragmentation of Multimaterial Fibers Via Polymer Cold-Drawing

Research
MIT MRSEC researchers have demonstrated for the first time a selective cold drawing process in multi-material fibers in which one material undergoes cold-drawing while the others do not.

Hybrid 2D-Ferroelectric Structures for Information Technology

Research

Nebraska MRSEC researchers have implemented hybrid electronic devices comprising two-dimensional (2D) materials and ferroelectric thin films of barium titanate (BaTiO3) that exhibit polarization-controlled non-volatile modulation of the electronic properties.
