The effects of power ultrasound (US) pretreatment on the preparation soy protein isolate hydrolysate (SPIH) prepared at same degree hydrolysis (DH) 12 % were measured. Cylindrical was modified into mono-frequency (20, 28, 35, 40, 50 kHz) ultrasonic cup coupled with an agitator to make it applicable for high density SPI (soy isolate) solutions (14 %, w/v). A comparative study alterations hydrolysates molecular weight, hydrophobics, antioxidants and functional properties change as well their...
A novel hybrid time-frequency domain equalization scheme is proposed and experimentally demonstrated to mitigate the white light emitting diode (LED) nonlinearity in visible communication (VLC) systems based on orthogonal frequency division multiplexing (OFDM). We handle linear nonlinear distortion separately a OFDM system. The part equalized compensated by an adaptive time equalizer (N-TDE). experimental results show that with only small number of parameters can efficiently LED...
Abstract Owing to the superior properties of wide bandgap, high carrier mobility, thermal conductivity and stability, 4H silicon carbide (4H-SiC) holds great promise for applications in electrical vehicles, 5G communications, new-energy systems. Although industrialization 150 mm 4H-SiC substrates epitaxial layers has been successfully achieved, existence a density dislocations is one most severe bottlenecks advancing performance reliability based high-power high-frequency electronics. In...
The role of dopants on deformation and mechanical properties 4H silicon carbide (4H-SiC) is proposed by using nanoindentation. It found that the hardness, elastic modulus, fracture toughness 4H-SiC substrate wafers all decrease order vanadium (V) doping, undoping, nitrogen (N) doping. For three types 4H-SiC, basal plane dislocations (BPDs), threading edge dislocations, cracks are formed during Polymorph transitions from to amorphous SiC 3C-SiC as penetration depth indent increases subsurface...
Interfacial resistance of the charge carriers across TiO2 to cocatalysts is one main limiting factors for realizing high photocatalytic efficiency water oxidation. Herein, an amorphous TiOx layer introduced on surface crystalline catalyst form core–shell structure (am@TiO2) via oxidation corrosion method. Owing disordered Ti–O layer, obtained am@TiO2 exposes abundant −OH groups homogeneous loading nanosized IrOx, while carrier interfacial migration substantially enhanced. The as-prepared...
Abstract In this letter, we optimize the flatness of 4H silicon carbide (4H-SiC) wafers by tuning sequence single-sided lapping, enlightened different mechanical properties Si face and C 4H-SiC. After wire sawing, coarse lapping fine are carried out to rapidly remove surface damage 4H-SiC wafers. From point view controlling values bow warp wafers, coarse-lapping C-face followed Si-face is beneficial, while preferred fine-lapping lapping. Nanoindentation tests indicate that has higher...

An unexpected rearrangement of pyrazolium halides was observed, presenting an efficient approach for the synthesis 1,2-dihydroquinazolines under mild conditions.
Cr and Al coating were respectively deposited on Zr-4 alloy by magnetron sputtering high temperature oxidation (HTO) tests conducted in air environment at 1200 °C for 3 h Cr-coated Al-coated specimens. The morphology phase composition of the specimens detected SEM, EDS XRD. adhesion properties characterized scratch test. XRD results revealed that two coatings crystalline with preferred orientation. testing showed critical load was higher than coating. After HTO test, specimen intact without...
Layered asymmetrically clipped optical orthogonal frequency division multiplexing (LACO-OFDM) has a high spectral efficiency. However, an iterative detection with pair of fast Fourier transform (FFT) and inverse (IFFT) is required for LACO-OFDM, which increases the complexity receiver LACO-OFDM. In this paper, performance single FFT analyzed LACO-OFDM in visible light communications. single-FFT receiver, different layers ACO-OFDM signals are distinguished time domain without FFT/IFFT pair....
An iterative pairwise maximum likelihood (ML) receiver is proposed for asymmetrically clipped optical orthogonal frequency division multiplexing (ACO-OFDM) in visible light communications (VLC). With the aid of ML detection, half received ACO-OFDM samples are forced to zero time domain. However, when signal-to-noise ratio (SNR) low, detection may cause misjudgment. symbols detected domain and SNR gain 3 dB could be available. Simulation results show that without iteration provides...
