Nonreciprocity in Uniform Time-Varying Materials Using Spatial Dispersion

Xiaoqiang Wang, Mohammad Sajjad Mirmoosa

Conventionally, nonreciprocity in time-varying systems is achieved by exploiting both temporal and spatial modulations. In this paper, we introduce a concept of magnetless bianisotropic time-modulated systems that support nonreciprocal wave propagation at ...

Exploring Perovskite-Metal Nanoassemblies for Photocatalytic Applications

Seryio Saris

The development of sustainable, renewable and economic chemical processes lies in the centre of todayâ s global energy challenge. Like in plants, artificial photosynthesis offers an auspicious solution in harvesting solar energy and storing it in chemical ...

CsPbBr3 QD/AlOx inorganic nanocomposites with exceptional stability in water, light and heat

Raffaella Buonsanti, Emad Oveisi, Duncan Thomas Lindsay Alexander, Anna Loiudice, Seryio Saris

Herein, the assembly of CsPbBr3 QD/AlOx inorganic nanocomposites, by using atomic layer deposition (ALD) for the growth of the amorphous alumina matrix (AlOx), is described as a novel protection scheme for such QDs. The nucleation and growth of AlOx on the ...

A greedy non-intrusive reduced order model for fluid dynamics

Jan Sickmann Hesthaven

We introduce a greedy non-intrusive reduced order method(ROM) for parameterized time-dependent problems with an emphasis on problems in fluid dynamics. The non-intrusive ROM is based on two-level proper orthogonal decomposition(POD) to extract temporal and ...

Accessible triple-phase boundary length: A performance metric to account for transport pathways in heterogeneous electrochemical materials

Jan Van Herle, Marco Cantoni, Arata Nakajo

The performance of materials for electrochemical energy conversion and storage depends upon the number of electrocatalytic sites available for reaction and their accessibility by the transport of reactants and products. For solid oxide fuel/electrolysis ce ...

Modelling occupants’ personal characteristics for thermal comfort prediction

Darren Robinson, Frédéric Haldi

Based on results from a field survey campaign conducted in Switzerand, we show that occupants’ variations in clothing choices, which are relatively unconstrained, are best described by the daily mean outdoor temperature and that major clothing adjustments ...

On the analytic-numeric treatment of weakly singular integrals on arbitrary polygonal domains

Juan Ramon Mosig, Athanasios Polymeridis, Sergio Lopez Pena

An alternative analytical approach to calculate the weakly singular free-space static potential integral associated to uniform sources is presented. Arbitrary oriented flat polygons are considered as integration domains. The technique stands out by its mat ...

Three-dimensional (3D) polypyrrole microstructures with high aspect ratios fabricated by localized electropolymerization

Giorgio Margaritondo

We present the three-dimensional (3D) growth of polypyrrole (PPy) microstructures with high aspect ratios (HAR) by a localized electropolymerization. The radicals formed by an oxidation of Py monomer is localized on the targeting area due to a confinement ...

A new look at atomic broadcast in the asynchronous crash-recovery model

André Schiper, Sergio Mena

Atomic broadcast in particular, and group communication in general, have mainly been specified and implemented in a system model where processes do not recover after a crash. The model is called crash-stop. The drawback of this model is its inability to ex ...
