Wave mitigation in ordered networks of granular chains [PDF]

open access: yes, 2013
We study the propagation of stress waves through ordered 2D networks of granular chains. The quasi-particle continuum theory employed captures the acoustic pulse splitting, bending, and recombination through the network and is used to derive its ...

Decoding Proton‐Coupled Electron Transfer Mechanism of Nicotine for Multi‐Scenario Portable Electrochemical Sensing

open access: yesAdvanced Science, EarlyView.
A key challenge in nicotine electroanalysis is the unresolved complexity of its interface process, which directly determines sensor metrics. Herein, the proton‐coupled electron transfer mechanism of nicotine is decoded for multi‐scenario portable electrochemical sensing.

On the Limiting Stokes' Wave of Extreme Height in Arbitrary Water Depth

open access: yes, 2018
As mentioned by Schwartz (1974) and Cokelet (1977), it was failed to gain convergent results of limiting Stokes' waves in extremely shallow water by means of perturbation methods even with the aid of extrapolation techniques such as Pad\'{e} approximant.

Special solutions to a compact equation for deep-water gravity waves [PDF]

open access: yes, 2012
Recently, Dyachenko & Zakharov (2011) have derived a compact form of the well known Zakharov integro-differential equation for the third order Hamiltonian dynamics of a potential flow of an incompressible, infinitely deep fluid with a free surface ...

Integrated Experimental and Theoretical Insights into Defect‐Induced Functionalities of Cobalt Doped NiO for Multifunctional Solar‐Driven Applications

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Rational defect engineering in Co‐doped NiO nanostructures, synthesized via a sustainable green route, enables precise bandgap modulation and defect‐state tailoring. Combined experimental–density functional theory analysis identifies 15% Co doping as the optimal threshold for maximizing photocatalytic degradation, photothermal response, and hydrogen ...

Tsunami generation by paddle motion and its interaction with a beach: Lagrangian modelling and experiment [PDF]

open access: yes, 2013
A 2D Lagrangian numerical wave model is presented and validated against a set of physical wave-flume experiments on interaction of tsunami waves with a sloping beach. An iterative methodology is proposed and applied for experimental generation of tsunami-

Interaction of highly nonlinear solitary waves with rigid polyurethane foams

open access: yesInternational Journal of Solids and Structures, 2018
Abstract Experiments and simulations are performed to study the interaction of solitary waves in a granular crystal with a plastically compressible and rate-sensitive test medium in the form of rigid polyurethane (PU) foam. We study the effects of the foam's compressive strength and elastic modulus on the nonlinear wave dynamics near the interface ...

Suprathermal Soliton Solutions to Nonlinear Schrödinger Equation

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Maxwell distributions are very difficult to find in the low‐pressure environment far away the Earth atmosphere, permeated by high temperatures, various types of radiation, highly energetic particles, space debris, and subjected to microgravity, presenting crucial challenges for spacecraft design and operations, and affecting astronaut's health.

Wave Propagation in a Strongly Nonlinear Locally Resonant Granular Crystal

open access: yes, 2017
In this work, we study the wave propagation in a recently proposed acoustic structure, the locally resonant granular crystal. This structure is composed of a one-dimensional granular crystal of hollow spherical particles in contact, containing linear ...

Recent Advances on Self‐Powered Metal Halide Perovskite Photodetectors

open access: yesEcoEnergy, EarlyView.
This review outlines that metal halide perovskites, with high absorption coefficient and carrier mobility, enable self‐powered photodetectors. These devices operate without external power, with improvements via structural optimization, film engineering, and defect passivation, showing promise in smart sensors and Internet of Things applications ...
