Antibiotics are extensively used in health sectors, animal husbandry, and agriculture, which raises serious concerns nowadays due to their presence in surface water, groundwater, soil, sediment, and plants. Antibiotics in water can cause the accumulation and spread of antibiotic-resistant genes that have a serious impact on the environment. Moreover, due to the refractory and persistent nature of antibiotics, conventional wastewater treatment technologies including physio-chemical and biological treatments are inefficient for antibiotic wastewater treatment. In recent times, Electrochemical Advanced Oxidation Processes (EAOPs) have been reported to be effective in the treatment of antibiotic-contaminated wastewater. These specialized techniques produce very reactive and oxidizing intermediate •OH radicals which readily degrade the antibiotics. In this article three most important EAOPs, Electro Oxidation (EO), Photo Electro Catalytic Oxidation (PEC), and Electro Fenton (EF) are reviewed along with their classification, performance in different antibiotics, influencing factors e.g., anode-cathode materials, pH, current density, initial concentration, temperature, and supporting electrolytes. These processes offer eco friendly, sustainable, cost-effective methods for treating antibiotics. Moreover, the feasibility of EAOPs in industrial wastewater treatment has not been properly established due to toxic intermediates, high cost, incapable to handle a large volume of wastewater, its performance only at ideal conditions, degrade only a few antibiotics, and mass transfer limitations. Consequently, combining membrane separation and conventional biological treatments as pre- or post-treatments of EAOPs can effectively address toxicity reduction and the handling of large volumes of wastewater. In addition, the energy consumption in a single EO process is higher than the combined processes. To constructively write this review, data have been collected from renowned publishers e.g., ScienceDirect, Springer, Willey, American Chemical Society Publications, etc. The possibilities, challenges, and future outlooks for the scale-up and commercialization of existing lab-based EAOPs have been discussed for the sustainable use of EAOPs in treating toxic and bio persistent antibiotic compounds from wastewater. Furthermore, the research gaps mentioned in this paper can encourage future researchers to utilize the merits of EAOPs and combined processes for achieving high degradation efficiency of antibiotics at low cost and establishing it commercially.

Today, textile-based wearable electronic devices (textronics) have been developed by taking advantage of nanotechnology and textile substrates. Textile substrates offer flexibility, air permeability, breathability, and wearability, whereas, using nanomaterials offers numerous functional properties, like electrical conductivity, hydrophobicity, touch sensitivity, self-healing properties, joule heating properties, and many more. For these reasons, textronics have been extensively used in many applications. Recently, new emerging two-dimensional (2D) transition metal carbide and nitride, known as MXene, nanomaterials have been highly considered for developing textronics because the surface functional groups and hydrophilicity of MXene nanoflakes allow the facile fabrication of MXene-based textronics. In addition, MXene nanosheets possess excellent electroconductivity and mechanical properties as well as large surface area, which also give numerous opportunities to develop novel functional MXene/textile-based wearable electronic devices. Therefore, this review summarizes the recent advancements in the architectural design of MXene-based textronics, like fiber, yarn, and fabric. Regarding the fabrication of MXene/textile composites, numerous factors affect the functional properties (e.g. fabric structure, MXene size, etc.). All the crucial affecting parameters, which should be chosen carefully during the fabrication process, are critically discussed here. Next, the recent applications of MXene-based textronics in supercapacitors, thermotherapy, and sensors are elaborately delineated. Finally, the existing challenges and future scopes associated with the development of MXene-based textronics are presented.

(Scopus, 2024-04-18) Uddin, Md. Ripaj; Khandaker, Mayeen Uddin; Ahmed, Shamim; Abedin, Md Jainal; Hossain, Syed Md. Minhaz; Mansur, Muhammad Abdullah Al; Akter, Shakila; Akbor, Md. Ahedul; Jamal, AHM Shofiul Islam Molla; Rahman, Mohammed M.; Kazi, Mohsin; Siddique, Md. Abu Bakar; Idris, Abubakr M.
Saltwater intrusion in the coastal areas of Bangladesh is a prevalent phenomenon. However, it is not conducive to activities such as irrigation, navigation, fish spawning and shelter, and industrial usage. The present study analyzed 45 water samples collected from 15 locations in coastal areas during three seasons: monsoon, pre-monsoon, and post-monsoon. The aim was to comprehend the seasonal variation in physicochemical parameters, including water temperature, pH, electrical conductivity (EC), salinity, total dissolved solids (TDS), hardness, and concentrations of Na+, K+, Mg2+, Ca2+, Fe2+, HCO3-, PO43-, SO42-, and Cl-. Additionally, parameters essential for agriculture, such as soluble sodium percentage (SSP), sodium absorption ratio (SAR), magnesium absorption ratio (MAR), residual sodium carbonate (RSC), Kelly’s ratio (KR), and permeability index (PI), were examined. Their respective values were found to be 63%, 16.83 mg/L, 34.92 mg/L, 145.44 mg/L, 1.28 mg/L, and 89.29%. The integrated water quality index was determined using entropy theory and principal component analysis (PCA). The resulting entropy water quality index (EWQI) and SAR of 49.56% and 63%, respectively, indicated that the samples are suitable for drinking but unsuitable for irrigation. These findings can assist policymakers in implementing the Bangladesh Deltaplan-2100, focusing on sustainable land management, fish cultivation, agricultural production, environmental preservation, water resource management, and environmental protection in the deltaic areas of Bangladesh. This research contributes to a deeper understanding of seasonal variations in the hydrochemistry and water quality of coastal rivers, aiding in the comprehension of salinity intrusion origins, mechanisms, and causes.

In recent years, a new class of highly crystalline advanced permeable materials covalent-organic frameworks (COFs) have garnered a great deal of attention thanks to their remarkable properties, such as their large surface area, highly ordered pores and channels, and controllable crystalline structures. The lower physical stability and electrical conductivity, however, prevent them from being widely used in applications like photocatalytic activities and innovative energy storage and conversion devices. For this reason, many studies have focused on finding ways to improve upon these interesting materials while also minimizing their drawbacks. This review article begins with a brief introduction to the history and major milestones of COFs development before moving on to a comprehensive exploration of the various synthesis methods and recent successes and signposts of their potential applications in carbon dioxide (CO2) sequestration, supercapacitors (SCs), lithium-ion batteries (LIBs), and hydrogen production (H2-energy). In conclusion, the difficulties and potential of future developing with highly efficient COFs ideas for photocatalytic as well as electrochemical energy storage applications are highlighted.

(Elsevier, 2023-09-01) Rahman, Tanzim Ur; Roy, Hridoy; Fariha, Athkia; Shoronika, Afrina Zaman; Al-Mamun, Md. Rashid; Islam, Syed Z.; Islam, Md. Shahinoor; Marwani, Hadi M.; Islam, Aminul; Alsukaibi, Abdulmohsen K.D.; Rahman, Mohammed M.; Awual, Md. Rabiul
In recent years, solar energy-driven photocatalysis materials have drawn significant attention to addressing the global energy and environmental crisis. However, many of the semiconductor photocatalysts are unable to absorb the visible light of the solar spectra due to their wide band gap. The incorporation of a foreign element such as a dopant in the lattice of these photocatalysts was shown to reduce their band gap and enhance visible light absorption. The doping of semiconductors can be performed using several techniques such as sol–gel, hydrothermal, solvothermal, and plasma-based doping. However, plasma-based doping has been considered a highly efficient approach due to the reduction of the band gap to a large extent, enhancement of visible light absorption, and remarkable photocatalytic activities under visible light illumination. The plasma-based doping approach offered many advantages such as high reactivity, process simplicity, scalability, energy efficiency, homogeneous doping, no chemical inventory, low pressure, and low-temperature operation, and flexibility of operation under gas and liquid phase media. Further advancement of plasma-based doping can be achieved through more theoretical studies allowing an in-depth understanding of the mechanisms and interactions of the species involved. This will facilitate the synthesis and application of doped photocatalysts in a cost-effective manner. This review surveyed recent advances in a wide range of semiconductor photocatalysts doped with various dopants using plasma treatment. Various plasma methods for doping semiconductor photocatalysts and their fundamental mechanisms were discussed. The performance characteristics of the plasma-doped photocatalysts were compared to other methods in terms of energy and environmental applications including degradation of environmental contaminants and solar fuel production such as hydrogen production from water splitting using visible light-driven solar energy. Finally, potential future research directions were recommended for the applications of the efficient photocatalysts developed by plasma treatment.

(Elsevier, 2023-07-29) Suhan, Md. Burhan Kabir; Al-Mamun, Md. Rashid; Farzana, Nawshin; Aishee, Sirazam Munira; Islam, Md. Shahinoor; Marwani, Hadi M.; Hasan, Md. Munjur; Asiri, Abdullah M.; Rahman, Mohammed M.; Islam, Aminul; Awual, Md. Rabiul
Rapid industrialization and urbanization emphasized water purification and the production of carbon-neutral fuels. State-of-the-art technology that is low-cost, long-lasting, and easy to implement is required to address these issues. In this context, substantial developments in green synthesis technology have provided a more efficient, effective, and affordable procedure. One possible paradigm worth considering is a circular system that purifies water and produces biomass. Titanium dioxide-based photocatalysts (TPs) can be a great tool due to their outstanding properties, which can be modified for improving photocatalytic activities in various advanced oxidation process applications. In recent years, there has been a significant increase in the attention given to the development of environmentally sustainable TPs. A comprehensive analysis of nearly 300 academic articles in this study has revealed significant shortcomings in effectively utilizing TPs. The primary objective of this paper was to address these gaps that need to be filled in order to ensure the efficient and sustainable utilization of TPs in wastewater treatment. Accordingly, this paper comprehensively reviewed TiO2’s features, including structure, properties, synthesis methods, photocatalytic activities, mechanism, structure modifications, applications, treatment cost analysis, and catalysts reuse in wastewater treatment. Finally, in order to ensure the sustainability of this wastewater treatment technique and achieve the goal of the circular economy, the concept of waste-to-resource has been introduced. The implementation of the aforementioned approach may serve as a valuable means of achieving environmentally sustainable outcomes in the field of wastewater treatment.
