Abstract null null The Photovoltaic generation inherits the instability due to the variability and non-availability of solar irradiation at times. Such unstable generation will cause grid management, planning, and operation issues. Researchers have proposed several classical and advanced algorithms to forecast the power generation of photovoltaic plants to avoid such unsuitability issues. Artificial Neural Networks advancement has pushed them in power forecasting, ranging from yearly to hourly p...

Abstract null null Herein, 3D flower-like δ-MnO2, MXene and δ-MnO2/MXene in-situ hybrid (IH) composites were prepared (via hydrothermal and solution treatment methods) for the effective removal of Cr (VI) from the contaminated water. The effect of various experimental parameters including contact time, pH levels and initial Cr (VI) ions concentration was determined and compared under static conditions. The kinetics of Cr (VI) adsorption onto δ-MnO2, MXene, and IH confirmed the existence of a pse...

Abstract MnO2 nanostructures with three distinct architectures, namely flower, balk and tube-like, have been synthesized through a single step microwave assisted hydrothermal method at different reaction temperatures (110 °C, 140 °C and 180 °C). The characterization of as prepared MnO2 samples were performed by means of Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The N2 adsorption-desorption isotherms revealed th...

Herein, we report terahertz (THz) shielding of flexible MXene (Ti3C2Tx)/MWCNT/PVA polymer composite films by using THz time-domain spectroscopy (THz-TDS) in 0.1–2.0 THz frequency range. The polymer composite with 42 µm thickness exhibited an excellent shielding effectiveness of 36 dB at 2 THz which is much higher than most of the reported materials for THz shielding with comparable thickness. The absorption coefficient increases from 100 cm−1 for pristine PVA to ~ 600 cm−1 for 20 wt% MXene/1.5 w...

In this paper, we presented an autonomous control framework for the wall following robot using an optimally configured Gated Recurrent Unit (GRU) model with the hyperband algorithm. GRU is popularly known for the time-series or sequence data, and it overcomes the vanishing gradient problem of RNN. GRU also consumes less memory and is computationally more efficient than LSTMs. The selection of hyper-parameters of the GRU model is a complex optimization problem with local minima. Usually, hyper-pa...

Industrial utilization of nuclear resources greatly depends on the effective treatment of nuclear waste. The efficient removal of radioactive nuclides from liquid effluents by using different adsorbents has thus become crucial. Herein, for the first time, two-dimensional transition metal carbides (MXenes) are investigated as scavengers of cesium (Cs+) from contaminated water. Due to the combined advantages of the layered structure and the presence of heterogeneous sites (hydroxyl, oxygen and flu...

Abstract Penicillin fermentation is a batch process used for the industrial production of penicillin. In this paper, a fault detection scheme is designed for this process for a reliable operation. Since practical systems are subjected to disturbances and noises, designed scheme might be unreliable. To cope with this problem, optimization is also considered in the design by identifying an optimized parity vector directly from the process data without going into the details of system model using s...
