After double mesa etching a SiO2 passivation is used to insulate the mesa sidewalls from the Al signal contacts.
Inset: Maximum positions Emax of EL spectra as function of the injected electrical power.
The inset shows only the EL intensity at a current density of 510 kA/cm2.
Direct bandgap EL emission at room temperature is clearly shown for all processed LEDs.

Properties of Rolled and Extruded Semiproducts Made of New Al-Cu-Mg-Ag Heat-resistant B-1213 Alloy I.N.
In order to solve this problem, VIAM have performed a R&D work to create heat-resistant alloy based on Al-Cu-Mg system alloyed with Ag.
According to the data of paper [5], extruded AK4-1ch alloy semiproducts have the following properties in longitudinal direction: UTS = 420 MPa, 0.2%YS = 380 MPa, El = 9 %.
The sheets showed a high level of fatigue life, which is typical for long-life Al-Cu-Mg alloys.
Besides the developed heat-resistant Al-Cu-Mg alloys, VIAM had created a range of heat-resistant Al-Cu-Mn alloys (Russian designations - D20, D21) with high content of copper (up to 7 %) and Cu/Mg ratio ≈ 20.

Tool Wear and Form Accuracy in Ultrasonic-Assisted Milling of Soda-Lime Glass Yasmine El-Taybany1,a*, Mohab Hossam1,2,b, Hassan El-Hofy1,c 1Department of Industrial Engineering and Systems Management, School of Innovative Design Engineering, Egypt-Japan University of Science and Technology, P.O.
Shen et al. [4] investigated the wear characteristics of the diamond wheel during UAG of the alumina ceramic.
Fang et al. [7] stated that rotary ultrasonic machining had less tool wear during the side milling of K9 optical glass.
Dahnel et al. [11] concluded that ultrasonic assisted drilling of CFRP and titanium alloys resulted in less tool wear rate compared to conventional drilling.

Experimental Procedure The starting powders were TiC0.6 (<45µm), Si (<70 µmφ), and Al (<45 µmφ), which were mixed with a SPEX shaker mill apparatus for 10 min.
The powder mixture of TiC0.6/Si and TiC0.6/Al were used to synthesize Ti3SiC2 and Ti3AlC2, respectively.

According to [7, 18], intensive absorption bands in the range of 850…1100 сm-1refer to valence vibrations of Si-O-Si and Al-O-Al links, yet, low-frequency bands in the range of 450…600 сm-1 relate to deformation vibrations of Si-O-Si and Al-O-Si links.
