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

open access: yes
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 ...

Ground‐State Charge‐Transfer Doping in Donor–Acceptor Semiconducting Polymers

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates controlled ground‐state charge‐transfer complex formation (GS‐CTC) and doping in a series of diketopyrrolopyrrole‐based donor–acceptor semiconducting polymers paired with a π‐conjugated penta‐t‐butylpentacyanopentabenzo[25]annulene “cyanostar” macrocycle. Complementary experimental techniques show how subtle molecular, electronic,

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

open access: yes
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

Desert Plant Inspired Hierarchical Nanofibrous Membranes for Integrated Solar Desalination and Heavy Metal Remediation

open access: yesAdvanced Functional Materials, EarlyView.
An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...

Dynamics and wave analysis in longitudinal motion of elastic bars or fluids

open access: yesAin Shams Engineering Journal
We look at the bifurcation analysis, chaotic behavior, multistability, and sensitivity analysis of the van der Waals equation, which is used in science and engineering to study the dynamics of various structures. The variant van der Waals equation covers

Density functional theory for van der Waals complexes: Size matters [PDF]

open access: yes
Over the past 25 years there has been remarkable progress towards accurate description of nonbonded interactions within the context of density functional theory (DFT).

An Adaptive Inhibitory WSe2 Transistor for Retinomorphic In‐Sensor Image Processing

open access: yesAdvanced Functional Materials, EarlyView.
Conventional retinomorphic devices typically require deliberate gate‐bias tuning for each illumination condition. In this paper, we demonstrate an adaptive inhibitory WSe2 transistor that uses photo‐induced regime shift between the subthreshold and accumulation modes to achieve decision‐free, intensity‐adaptive image processing within a single pixel ...

Effects of van der Waals Force and Thermal Stresses on Pull-in Instability of Clamped Rectangular Microplates

open access: yesSensors, 2008
We study the influence of von Karman nonlinearity, van der Waals force, and a athermal stresses on pull-in instability and small vibrations of electrostatically actuated mi-croplates.
