Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Tunable Interlayer Interactions in 2D van der Waals Frameworks [PDF]

Two-dimensional materials can be isolated as monolayer sheets when interlayer interactions involve weak van der Waals forces. These rigorously atomically thin structures enable novel topological physics and open chemical questions of how to tune the ...

Giant chiral magnetoelectric oscillations in a van der Waals multiferroic

Nature
Helical spin structures are expressions of magnetically induced chirality, entangling the dipolar and magnetic orders in materials1–4. The recent discovery of helical van der Waals multiferroics down to the ultrathin limit raises prospects of large ...

Van der Waals Interactions and Exciton Condensation [PDF]

Proceedings of the National Academy of Sciences, 1971
It is shown that the van der Waals interaction can lead at low temperatures to a condensed state of excitons with properties in qualitative agreement with the observations of exciton droplets. Our calculation gives a binding energy of the correct sign and magnitude for the exciton condensate.

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

A General Method for Synthesizing van der Waals and Non-van der Waals Moiré Superlattices from Molecular Crystals [PDF]

Quantum materials have received a lot of interest in recent years because of their unusual and remarkable properties. Angular stacking of two-dimensional (2D) nanoscale crystalline sheets into interacting superstructures, such as moiré superlattices, can

Preserving the Surface Activity of Lung Surfactant Using Soft Nebulization

Small Science
Inhalable aerosols produced by nebulization offer a promising noninvasive route for lung drug delivery. Yet, high shear stresses during nebulization are highly detrimental to many complex biopharmaceuticals, such as lung surfactants, leading to ...

Theory of coherent van der Waals matter [PDF]

Physical Review E, 2014
We explain in depth the previously proposed theory of the coherent Van der Waals(cVdW) interaction - the counterpart of Van der Waals (VdW) force - emerging in spatially coherently fluctuating electromagnetic fields. We show that cVdW driven matter is dominated by many body interactions, which are significantly stronger than those found in standard Van

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces
