Advanced Functional Materials, EarlyView.A reconfigurable RRAM platform utilizing thermally pre‐formed filaments (TPFs) is developed to realize robust hardware security. By exploiting the thermodynamic stochasticity of TPFs, exceptionally reliable physically unclonable functions (PUFs) are achieved.

A Ring Silencer Design for Reducing Noise of Axial Fan
, 2014 [[abstract]]In this paper, a ring silencer design for reducing the noise of axial fans is presented. The noise sources on axial fans are usually caused by the fluctuating pressure distribution on the surface of fan blade. Most of the sources are near the

Advanced Functional Materials, EarlyView.Rutile GeO2${\rm GeO}_{2}$ exhibits orientation‐dependent heat transport with temperature‐dependent anisotropy, showing higher cross‐plane thermal conductivity along [001] than along the equivalent in‐plane [100] and [010] directions. Temperature‐dependent TDTR measurements and first‐principles phonon calculations identify the microscopic phonon ...

Unsteady simulation of tonal noise from isolated centrifugal fan
, 2018 In this study, tonal noise from an isolated centrifugal fan is investigated using unsteady Reynolds-averaged Navier-Stokes (URANS) simulations. Isolated centrifugal fans are often used in ventilation systems and play an important role in producing tonal ...

Advanced Healthcare Materials, EarlyView.This work introduces a microsphere‐templated strategy to fabricate reprocessable PEDOT:PSS syntactic foams with tunable porosity, stable conductivity, and 3D printability. In situ PEDOT:PSS coatings create a conductive network that maintains electrical performance at high void fractions.

The Journal of the Acoustical Society of America, 1971 The two traditional broad-band fan noise generation mechanisms are “noise due to incident turbulence” and “noise due to vortex shedding.” These might be called “aerodynamicists' mechanisms,” since they are both rooted in fluctuating lift concepts derived from two-dimensional incompressible unsteady aerofoil theory.

The Noise Problem in the Application of Fans [PDF]
The Journal of the Acoustical Society of America, 1935 This paper stresses the noise elements in the application of fans, particularly those of the propeller type, where the apparatus must operate in quiet surroundings. The sources of such noise are divided into the inherent noise of the fan, and the five classes of noise which tend to modify this inherent noise as follows: (1) Noise increase due to ...

Acoustic liner optimisation and noise propagation through turbofan engine intake ducts
, 2013 The research in this thesis explores the prediction of fan noise propagation through turbofan engine intakes and its radiation to the far-field. The performance of acoustic liners installed in intakes to attenuate noise is the focus of the study.
