Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow
Advanced Functional Materials, EarlyView.Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.

Controllability of a viscoelastic plate using one boundary control in displacement or bending [PDF]
arXiv, 2016 In this paper we consider a viscoelastic plate (linear viscoelasticity of the Maxwell-Boltzmann type) and we compare its controllability properties with the (known) controllability of a purely elastic plate (the control acts on the boundary displacement or bending). By combining operator and moment methods, we prove that the viscoelastic plate inherits

Effect of Viscoelasticity on the Natural Frequencies of Axially Moving Continua
Advances in Mechanical Engineering, 2013 Linear models of axially moving viscoelastic beams and viscoelastic pipes conveying fluid are considered. The natural frequencies of the models are calculated. For both models, viscoelasticity terms are assumed to be of order one.

Advanced Functional Materials, EarlyView.A series of ultraviolet‐ and near‐infrared radiation sensitive photoactivatable hydrogels are developed that can be controlled spatiotemporally down to µm precisions using one‐ and two‐photon uncaging. The latent hydroxylamine‐, hydrazine‐, and amine uncaged moieties are used to photopattern a series of diverse proteins displaying complimentary ...

Linear and nonlinear viscoelastic arterial wall models: application on animals [PDF]
arXiv, 2016 This work deals with the viscoelasticity of the arterial wall and its influence on the pulse waves. We describe the viscoelasticity by a non-linear Kelvin-Voigt model in which the coefficients are fitted using experimental time series of pressure and radius measured on a sheep's arterial network.

Delayed instabilities in viscoelastic solids through a metric description [PDF]
arXiv, 2017 While determining the stability of an unconstrained elastic structure is a straightforward task, this is not the case for viscoelastic structures. Seemingly elastically stable conformations of viscoelastic structures may gradually creep until stability is lost, and conversely, creeping does not necessarily imply that a structure will eventually become ...

All‐Cellulose‐Based Photonic Glitters
Advanced Functional Materials, EarlyView.Uniform, disc‐shaped photonic CNC glitters with adjustable structural colors and diameters are fabricated on hydrophilic ethyl cellulose films using electrospray deposition. By employing patterned ethyl cellulose films with pre‐designed hydrophilic regions, photonic patterns can be created with these all‐cellulose‐based glitters, demonstrating their ...

Singular viscoelastic perturbation to soft lubrication
Physical Review ResearchSoft lubrication has been shown to drastically affect the mobility of an object immersed in a viscous fluid in the vicinity of a purely elastic wall. In this theoretical article, we develop a minimal model incorporating viscoelasticity, carrying out a ...

Nonlinear viscoelasticity of Hydrothane�
Journal of Materials Science: Materials in Medicine, 1996 The nonlinear viscoelastic behaviour of Hydrothane®, a hydrophilic polyurethane used for biomedical applications, has been studied. The material has been tested in stress-relaxation experiments in a range of deformation up to 25%. Isochrone curves have been predicted by using the rubber elasticity theory and separating strain and time effect.
