The electrical and the optical properties of tandem organic light-emitting devices (OLEDs) with stacked electroluminescence units were investigated to clarify the charge-generation mechanisms due to the existence of a charge-generation layer (CGL). The current density of the current limited devices with an 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile (HAT-CN) CGL was 35% higher than that of devices with a tungsten-oxide (WO3) CGL. The maximum current density of the current limited devices with a HAT-CN CGL was as high as 259 mA/cm2. The brightness of the tandem OLEDs with a HAT-CN CGL was 15% higher than that of the tandem OLEDs with a WO3 CGL due to an increase in the current density. The charge-generation mechanisms of tandem OLEDs with a CGL were described on the basis of the experimental results.

Experimental study on the laser direct fabrication (LDF) of stainless steel powder is carried out. Microstructure and properties of the deposited components are analyzed and tested with optical microscopy (OM), scanning electron microscopy (SEM) and electron probe microanalysis (EPMA) etc. Cracking generation mechanisms of this material are investigated, corresponding cracking control strategies have been proposed. Finally, fully dense stainless steel components free of defects and with perfect comprehensive mechanical properties have been produced.

Fill Level

Liquid sloshing is becoming a major source of noise in hybrid and high-end luxury cars, especially during acceleration/deceleration driving conditions. This is due to the reduction in noise from other sources, namely, engine, transmission system, road–tyre interaction and so on. Sloshing noise is highly dependent on fluid motion in the containers. Based on the fluid motion in the containers, sloshing is classified into different regimes. The present experimental study discusses the noise generation mechanisms for various sloshing regimes. It is done by emulating different sloshing regimes in a partially filled rectangular tank by imposing longitudinal periodic excitation. The effect of fill level on noise generation phenomenon in each regime is analysed, individually, using dynamic response parameters and high-speed camera images. In this study, the measured dynamic response parameters are pressure, force, acceleration and sound pressure levels as a function of time. The fundamental reasons for the cause of sloshing noise in partially filled rectangular tanks are identified in terms of fluid motion and its interaction with the surrounding objects. The excitations upto the sloshing resonance condition cause hydraulic jumps along the tank walls leading to hit noise. Excitations beyond the sloshing natural frequency cause the predominant interaction of surface waves with surrounding fluid leading to splash noise.

Impact Damping

In this article, an experimental study of a vertical particle impact damper under free excitation is investigated. Specific impact damping is determined for a primary structure (clamped-free beam) with an enclosure attached to its free end and containing a lead particle. The influence of some system parameters such as clearance and intensity of excitation are investigated. An analytical model based on the concept of an equivalent system with impacting mass is presented and used to compute the specific impact damping. Driven by the experimental observation, it has been shown that a high value of specific damping capacity was reached with a particle impact damper. The obtained results prove the efficiency of this process for achieving high structural damping.
