Abstract
In this report, we have synthesized three-dimensional and hydrophobic graphene-incorporated carbon aerogel (G-SCA) derived from sugar. G-SCA is being used as a multifunctional sorbent material for removing various advanced water soluble and insoluble pollutants Initially, G-SCA is being explored for the adsorption of nitrophenols, nitroaromatics (3-nitroaniline), insecticide (Phoskill), antibiotic (ciprofloxacin), and pharmaceutical drug precursor (pyridine). Later, same G-SCA is also explored in the absorption of various protic and aprotic organic solvents and oils (including crude oil, waste cooking oil, and waste Mobil oil), with excellent recyclability checked up to 10 cycles. Moreover, oil-water separation experiments are also being done in various industrial wastewater samples and seawater to support the real-life accessibility of present approach. Large-scale applicability of G-SCA is also checked by performing crude oil-seawater separation experiments using a laboratory-scale prototype demonstrating the successful continuous recovery of crude oil.
Explanation of The Research in Layperson’s Terms
This research demonstrates the synthesis of carbon aerogel from edible sugar followed by the incorporation of graphene oxide to make a near superhydrophobic and good water-floating sorbent material. Later, this sorbent material was used to decontaminate wastewater from advanced pollutants such as explosive wastes, expired antibiotics, pharmaceutical waste, insecticides, etc. This report also showed the practical demonstration of crude oil recovery from seawater, thus contributing to the circular economy process.

Practical Implementation or the Social Implications Associated with the Research
This work describes the synthesis of low-cost near superhydrophobic carbon aerogel, displaying its multiple applications in wastewater treatment from water-soluble and water-insoluble pollutants. It is also an alternative and cost-effective approach for recovering valuable oil and organic compounds from water rather than degrading or destroying them so they can be reused.

Unveiling Innovations: Dr Ghosh Publishes Findings on 300 GHz Communication Links
Dr Anirban Ghosh, an esteemed Assistant Professor in the Department of Electronics and Communication Engineering, has recently published a significant research paper titled “Channel Modeling and Characterization of Access, D2D, and Backhaul Links in a Corridor Environment at 300 GHz.” This paper has been featured in the prestigious Q1 Journal, IEEE Transactions on Antenna and Propagation, with an impressive impact factor of 4.6.
Dr Ghosh’s research delves into the intricate aspects of channel modelling and characterisation, focusing on access, device-to-device (D2D), and backhaul links within a corridor environment at a high frequency of 300 GHz. This study is poised to make substantial contributions to the field of wireless communication, particularly in enhancing the understanding and development of next-generation communication systems.
The publication in such a renowned journal underscores the quality and impact of Dr. Ghosh’s work, reflecting the cutting-edge research being conducted at SRM University – AP. The university community extends its heartfelt congratulations to Dr. Ghosh for this remarkable achievement and looks forward to his continued contributions to the field of electronics and communication engineering.
Abstract:
This paper presents comprehensive double-directional channel measurements at 300 GHz across various corridor scenarios, including Access, Device-to-Device (D2D), and Backhaul, using an in-house developed channel sounder. The measurements, validated by ray tracing simulations, reveal that while 300 GHz quasi-optical propagation in corridors can be modeled using ray optics, non-trivial propagation phenomena, such as quadruple-bounce reflections, also occur. To accurately model these mechanisms, a quasi-deterministic (QD) channel model combining deterministic and random components is proposed. The QD model results align well with observations, highlighting similar propagation mechanisms for Access and D2D scenarios, while Backhaul scenarios show Line-of-Sight (LoS) impacts from ceiling reflections. These findings are crucial for designing next-generation THz communication systems.
Explanation of Research in Layperson’s Terms
