Design and Electro-Thermo-Mechanical Behavior Analysis of Au/Si3N4 Bimorph Microcantilevers for Static Mode Sensing

Sensors, 2017
This paper presents a design optimization method based on theoretical analysis and numerical calculations, using a commercial multi-physics solver (e.g., ANSYS and ESI CFD-ACE+), for a 3D continuous model, to analyze the bending characteristics of an ...

Microfabricated Anisotropic Myobundles for the Scalable Production of Cardiac Tissue Grafts

Advanced Functional Materials, EarlyView.
Controlling the anisotropy of cardiac tissue remains an outstanding challenge in the field of cardiac tissue engineering. Here, we introduce an approach to generate anisotropic cardiac myobundles using cell‐adhesive, synthetic, electrospun fibers and stem cell‐derived cardiac fibroblasts.

Development of low noise cantilever deflection sensor for multienvironment frequency-modulation atomic force microscopy [PDF]

, 2005
We have developed a low noise cantilever deflection sensor with a deflection noise density of 17fm/√ Hz by optimizing the parameters used in optical beam deflection (OBD) method.

Charged regular black holes in quantum gravity: from thermodynamic stability to observational phenomena

European Physical Journal C: Particles and Fields
We investigate the thermodynamic, astrophysical, and observational properties of charged nonsingular black holes within the framework of quantum gravity and nonlinear electrodynamics.

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

Advanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...

Deflection range of water in heterogeneous permeable media

, 2015
Knowledge of mode of transport of fluid in soil is the basis for soil environmental engineering especially in transport of contaminants in groundwater. The study investigates the possible minimum and maximum angle of deflection of water through media of ...

Kaluza-Klein Multidimensional Models with Ricci-Flat Internal Spaces: The Absence of the KK Particles

Advances in High Energy Physics, 2013
We consider a multidimensional Kaluza-Klein (KK) model with a Ricci-flat internal space, for example, a Calabi-Yau manifold. We perturb this background metrics by a system of gravitating masses, for example, astrophysical objects such as our Sun.

First observation of scattering of sub-GeV electrons in ultrathin Si crystal at planar alignment and its relevance to crystal-assisted 1D rainbow scattering

Physics Letters B, 2018
Here we report on the first measurements of 255 MeV electron scattering by an ultrathin 0.58 μm Si(111) crystal at angles of incidence less than the Lindhard critical angle.

Dye‐Initiated Chirped Cholesteric Polymer Networks Exhibiting Broadband Dissipative Chiral Photonic Bands

Advanced Functional Materials, EarlyView.
A dye‐based photoinitiator acting as a structure‐directing element, guides the formation of a cholesteric polymer network that behaves as a chirped photonic structure with dissipative chiral coupling. Photopolymerization freezes a depth‐dependent helical pitch, broadening the Bragg resonance spectrum.

Concerning the Direction of the Aharonov-Bohm Deflection

, 2023
The interaction of a solenoid with a passing charged particle can be treated within classical or quantum physics. If charged particles pass around both sides of a solenoid, there is an experimentally-observed Aharonov-Bohm deflection of the double-slit ...
