“…The present study on utilization of agro‐waste like sugarcane bagasse for the removal of Optilan yellow and Lanasyn brown showed a significant reduction (maximum 98%) in dye concentration in all the cases in a column‐based system ( Figure and Tables 1 and 2 ). However, in an earlier investigation, Sharma and Nandi reported 95% removal of Malachite green dye in a batch system using sugarcane bagasse particles as an adsorbent. Sadaf and Bhatti studied the potential application of sugarcane bagasse as cost‐effective biomass for the treatment of real textile effluents and observed maximum chemical oxygen demand (COD) removal of 72.4–80.8% from dye effluents.…”

“…The untreated dye‐house wastewater poses a threat to the terrestrial and aquatic ecosystem and therefore, requires a pretreatment process for dye‐containing wastewater before its discharge to the surrounding. The synthetic dyes consist of azo, methane, nitro, and carbonyl groups which make them comparatively more recalcitrant to biological degradation processes . It is estimated that globally 280 000 tons of textile dyes are discharged in the dye‐containing industrial effluents every year .…”

“…Utilization of agricultural wastes for wastewater treatment is a novel and environment‐friendly approach which could be helpful in providing a solution for the problem of solid waste disposal. Several researchers used sugarcane bagasse as an adsorbent to remove different dyes from wastewater, especially in the batch study . A higher quantity of discarded sugarcane bagasse and adsorptive nature of sugarcane bagasse have increased its desirability for the remedy of environmental pollution in different ways .…”

The performance of a newly designed column bed device packed with chemically modified agro‐waste (sugarcane bagasse) is evaluated for efficient removal of two textile dyes, Optilan yellow and Lanasyn brown and textile industry dye effluent. The parameters used for performance evaluation are removal efficiency (R%), adsorption capacity (q), and breakthrough (Ce/C0). The column exhibits >90% removal of both the dyes and >80% removal of textile industry dye effluent. The experimental data are fitted to three models, viz., Thomas, Adams–Bohart, and Yoon–Nelson for understanding the kinetic behavior of adsorption. The results reveal that the Yoon–Nelson model is the best‐fitted model for both the dyes with R2 values 0.995 and 0.905 for Optilan yellow and Lanasyn brown, respectively. However, Thomas and Yoon–Nelson fit the best for textile industry effluent. Overall, this investigation provides baseline information about the column mode removal of textile dyes using the agro‐waste material as an adsorbent. The Fourier transform infrared spectroscopy spectra show the characteristic vibrational mode of CH stretching of hydroxyl group around 2800–3000 cm−1. The change in the vibrational pattern is evident after alginic acid treatment, indicating delignification of the bagasse after treatment.

“…where, I D is the current through the terminal between the drain to the source, V eff is the effective gate to source voltage [15] and is given by [15] for undoped GFET and is equal to 0.308 V [14] for 12% Bdoped GFET (latter is elaborated in the following paragraphs). C OX is equal to 3.6 mF/m 2 [15] with gate dielectric constant of 3.5. q is the charge of electron which is given by 1.6 � 10 −19 (c) The lattice structure of the pristine graphene has been preserved by B-or N-substitution doping [13,16]. In addition to it, substitution doping affects the effective mass (m*) of the carriers, which further increases with increase in dopant concentration.…”

An accurate electrical equivalent circuit model for boron-substitution doped graphene field effect transistor (GFET) is proposed to analyse the effects of memoryless nonlinearity on transconductance. The proposed equivalent circuit model is verified with the simulated results of an industry-standard circuit simulation tool. The fundamental figures of merit (FOMs), such as the second-and third-order harmonic distortion terms (HD 2 and HD 3), gain compression point (A in,1dB), second-and third-order intermodulation distortion terms (IM 2 and IM 3), and second-and third-order input intercept points (A IIP2 and A IIP3) are mathematically modelled for B-substitution doped GFET to examine the linear behaviour of the device. The expressions are validated by performing the single tone and double tone simulation test to the proposed equivalent circuit model using the industry-standard circuit simulator. The proposed model is compatible and predicts accurate results for both B-substitution doped and undoped GFET. The simulation results are having an excellent agreement with the mathematical model, which are also compared with the undoped GFET and conventional MOSFET. It is also observed that by Bsubstitution doping the graphene sheet significantly induces the bandgapt and hence enhances the linear behaviour of the B-substitution doped GFET and promises highly desirable linearity requirement in the analog/RF applications.

Graphene, a two-dimensional (2D) layered material has attracted much attention from the scientific community due to its exceptional electrical, thermal, mechanical, biological and optical properties. Hence, numerous applications utilizing graphene-based materials could be conceived in next-generation electronics, chemical and biological sensing, energy conversion and storage, and beyond. The interaction between graphene surfaces with other materials plays a vital role in influencing its properties than other bulk materials. In this review, we outline the recent progress in the production of graphene and related 2D materials, and their uses in energy conversion (solar cells, fuel cells), energy storage (batteries, supercapacitors) and biomedical applications.
