Thermal‐Driven Diode Polarity Switching From Competing Helical Superconducting States in WTe2/α‐Fe2O3 Heterostructures

Advanced Materials, EarlyView.
A Nb‐proximitized Josephson junction based on a WTe2/α‐Fe2O3 heterostructure exhibits a robust superconducting diode effect with programmable polarity. The diode direction can be trained by magnetic fields and switched by temperature cycling, revealing tunable finite‐momentum pairing states and competing superconducting states in symmetry‐broken ...

Superstructure assembly 2D by oriented attachment of PbX nanocrystals

, 2018
The current interest in materials with a nanoscopic 2D honeycomb geometry is due to their unique optoelectronic properties. In previous research in our group, we have shown that oriented attachment of colloidal lead selenide (PbSe) nanocrystals can ...

Formation of colloidal copper indium sulfide nanosheets by two-dimensional self-organization

, 2017
Colloidal 2D semiconductor nanosheets (NSs) are an interesting new class of materials due to their unique properties. However, synthesis of these NSs is challenging and synthesis procedures for materials other than the well-known Pb- and Cd ...

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

Advanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Measuring colloidal forces from particle position deviations inside an optical trap

, 2011
We measure interaction forces between pairs of charged PMMA colloidal particles suspended in a relatively low-polar medium (5 ( 3 ( 8) directly from the deviations of particle positions inside two time-shared optical traps.

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Fluorescent colloidal silica rods - synthesis and phase behavior

, 2012
Although the experimental study of spherical colloids has been extensive, similar studies on rod-like particles are rare because suitable model systems are scarce.

Strobes: An Oscillatory Combustion

, 2012
Strobe compositions belong to the class of solid combustions. They are mixtures of powdered ingredients. When ignited, the combustion front evolves in an oscillatory fashion, and flashes of light are produced by intermittence.
