Effect of environmental humidity on the ionic transport of poly(ethylene oxide) thin films by local dielectric spectroscopy
(RSC, 2020-03-03)
The effect of humidity on the ionic transport in the amorphous phase of poly(ethylene
oxide) thin films has been studied by via local dielectric spectroscopy. We explored a
controlled humidity range between 15 %RH and ...
Gold nanoparticles endowed with low-temperature colloidal stability by cyclic polyethylene glycol in ethanol
(The Royal Society of Chemistry, 2021-09-07)
The colloidal stability of metal nanoparticles is tremendously dependent on the thermal behavior of polymer brushes. Neat polyethylene glycol (PEG) presents an unconventional upper critical solution temperature in ethanol, ...
Overcoming the Exciton Binding Energy in Two-Dimensional Perovskite Nanoplatelets by Attachment of Conjugated Organic Chromophores
(Nature, 2020-04-20)
In this work we demonstrate a novel approach to achieve efficient charge separation in dimensionally and dielectrically confined two-dimensional perovskite materials. Two-dimensional perovskites generally exhibit large ...
Conditional Wave Function Theory: A Unified Treatment of Molecular Structure and Nonadiabatic Dynamics
(American Chemical Society, 2021-11-09)
[EN] We demonstrate that a conditional wave function theory enables a unified and efficient treatment of the equilibrium structure and nonadiabatic dynamics of correlated electron-ion systems. The conditional decomposition ...
Nematicity Arising from a Chiral Superconducting Ground State in Magic-Angle Twisted Bilayer Graphene under In-Plane Magnetic Fields
(American Physical Society, 2021-09-13)
Recent measurements of the resistivity in magic-angle twisted bilayer graphene near the superconducting transition temperature show twofold anisotropy, or nematicity, when changing the direction of an in-plane magnetic ...
Light-Driven Extremely Nonlinear Bulk Photogalvanic Currents
(American Physical Society, 2021-09-13)
We predict the generation of bulk photocurrents in materials driven by bichromatic fields that arc circularly polarized and corotating. The nonlinear photocurrents have a fully controllable directionality and amplitude ...
Influence of Backbone Curvature on the Organic Electrochemical Transistor Performance of Glycolated Donor-Acceptor Conjugated Polymers
(Wiley, 2021-09-01)
Two new glycolated semiconducting polymers PgBT(F)2gT and PgBT(F)2gTT of differing backbone curvatures were designed and synthesised for application as p-type accumulation mode organic electrochemical transistor (OECT) ...
Polycaprolactone Adsorption and Nucleation onto Graphite Nanoplates for Highly Flexible, Thermally Conductive, and Thermomechanically Stiff Nanopapers
(American Chemical Society, 2021-12-15)
[EN] Free-standing nanopapers based on graphene and its related materials have been widely studied and proposed for flexible heat spreader applications. Given that these materials are typically brittle, this work reports ...
TMDs as a platform for spin liquid physics: A strong coupling study of twisted bilayer WSe2
(American Institute of Physics, 2022)
[EN] The advent of twisted moire heterostructures as a playground for strongly correlated electron physics has led to a plethora of experimental and theoretical efforts seeking to unravel the nature of the emergent ...
Crystallization and Morphology of Triple Crystalline Polyethylene-b-poly(ethylene oxide)-b-poly(ε-caprolactone) PE-b-PEO-b-PCL Triblock Terpolymers
(MDPI, 2021-09-16)
The morphology and crystallization behavior of two triblock terpolymers of polymethylene, equivalent to polyethylene (PE), poly (ethylene oxide) (PEO), and poly (ε-caprolactone) (PCL) are studied: PE227.1-b-PEO4615.1-b-PCL3210.4 ...
