Qualitative analysis of a 3D multiphysics model for nonlinear ultrasonics and vibration induced heating at closed defects

Kevin Truyaert, Vladislav Aleshin, Koen van den Abeele

Upon exciting a material using elastic waves, the locally induced deformation at the interfaces of internally closed defects may cause nonlinear wave mechanics and dynamics in the form of clapping and friction. As a result, both phenomena instigate spectral broadening of the excitation spectrum as…

Facile and secure synthesis of porous partially fluorinated graphene employing weakly coordinating anion for enhanced high-performance symmetric supercapacitor

Ning Cao, Teng Wang, Rabah Boukherroub, Yinghui Cai, Yijiang Qin, Fashun Li, Peng Liu, Qingguo Shao, Mingle Liu, Xiaobei Zang

In this paper, porous partially fluorinated graphene (PFG) for supercapacitors (SCs) was fabricated by a mild and secure one-pot hydrothermal method utilizing weakly coordinating anion BF4− as the fluorine source. The hydrolysis rate of sodium fluoroborate was adjusted by controlling the reaction…

Exceptional Points and Skin Modes in Non-Hermitian Metabeams

Runcheng Cai, Yabin Jin, Yong Li, Timon Rabczuk, Yan Pennec, Bahram Djafari-Rouhani, Xiaoying Zhuang

We present a non-Hermitian metabeam exhibiting an exceptional point (EP) induced by enforcing parity-time (PT) symmetry through applied external forces. The EP is formed by the hybridization of two flexural wave modes and its output displacement is enhanced by attaching two pillars on top of the…

Plasticity of Conducting Polymer Dendrites to Bursts of Voltage Spikes in Phosphate Buffered Saline

Corentin Scholaert, Kamila Janzakova, Yannick Coffinier, Fabien Alibart, Sébastien Pecqueur

The brain capitalizes on the complexity of both its biochemistry for neurons to encode diverse pieces of information with various neurotransmitters and its morphology at multiple scales to route different pathways for neural interconnectivity. Conducting polymer dendrites can show similar features…

Perception of loudness changes induced by a phononic crystal in specific frequency bands

Arthur Paté, Nicolas Côté, Charles Croënne, Jerome O. Vasseur, Anne-Christine Hladky-Hennion

To study the influence of classical phononic crystal (PC) structures on the acoustical characteristics of a sound source, a combined acoustics/perceptual analysis is conducted on a PC specially designed to exhibit several spectral and wave vector properties in different audible frequency ranges.…

Modeling of access resistances and channel temperature estimation for GaN HEMT

Shariful Islam, Mohammad Abdul Alim, Abu Zahed Chowdhury, Christophe Gaquière

Accurate prediction of resistances at the transistor’s access zone and their temperature dependency are very important, since the current flow to the device depends on that region. In this paper, we have modeled the access resistances and have verified their temperature dependency with the…
