The effects of performance and emission parameters a mono-cylinder CI engine have been studied using new alternate fuel: Lemongrass oil (LGO) with nano additive (Cerium Oxide). study focuses on novel biosynthesis method (Plant-mediated synthesis) CeO 2 nano-additives from the Azadirachta indica plant, which is less toxic more compatible other chemical methods. simple, high-yielding, environmentally friendly alternative to Recently, green technique based impulsively decreasing elements such...
Multi-wavelength laser sources on silicon photonics can enable large spectral coverage for DWDM optical I/O links and leverage the scalability of a CMOS compatible process simultaneously. In this work, we report array four four-wavelength distributed feedback lasers that produce in total sixteen wavelength channels simultaneously with spacing 200 GHz output power 17 dBm per laser. We show integrated III-V/Si hybrid same die wafer-level bonded epitaxial III-V layer spans nm through 16...
We demonstrate the first quantum dot lasers integrated with 300mm silicon photonics. The measured devices show a linewidth enhancement factor near zero and are resilient to optical feedback up -16dB of back reflection.
We demonstrate a 256Gbps WDM transceiver with eight 200GHz-spaced wavelengths simultaneously modulated at 32Gbps and <1e-12 BER. The system includes silicon photonic PIC integrated lasers, microring modulators, SOAs, Ge photodetectors, co-designed CMOS EIC.
A low-power CMOS linear driver IC, optimized for microring modulator-based co-packaged optics, is presented. This 2.5 V ppd driver, assembled with a photonic achieves 2 dB TDECQ at 106 Gb/s PAM4 1.33 pJ/bit efficiency.
We demonstrate a 4-wavelength DFB laser with >8dBm output power per wavelength, <±0.5dB variations, 140GHz wavelength spacing, and <-140dB/Hz RIN. For data transmission at 64 Gb/s, we obtained comparable performance to benchtop laser.

The improvement of technologies necessitates using a meticulous heat dissipation method to enhance the exergy efficiency small air exchangers. To improve thermal performance, plain tube (PT) exchangers (HX) use passive inserts, such as dimpled twisted turbulator inserts (DTTI) and (TTI) filled with ternary hybrid nanofluid (THNF) based on water. Energy, use, environmental impacts in future are primary foci inquiry THNF replacement inserts. Using water operating fluid, copper oxide (CuO),...
