The demand for long-term, sustainable, and durable energy storage devices has been increasing to overcome global challenges and concerns associated with energy and environment conservation. In this context, it is required to develop high performance carbon-based electrode materials for energy storage devices using simple, economical, and green techniques. The present study proposes an environment-friendly approach for facile, large-scale synthesis of onion-like carbon nano-particles (CNOs) for t...

Abstract Despite the advancement in treatment processes, pathogenic bacterial contamination is very common and is a major threat to human health and safety. The limitations of modern detection technologies towards rapid detection and discrimination of bacterial pathogens and early availability of information of their antimicrobial susceptibility underpin the necessity for the continued development of novel bacterial sensors. Revolutions in nanotechnology have led to exceptional accomplishments i...

Abstract Clay-cellulose biocomposite (CCB) was synthesized in the present study. Spin and pressure-induced heating was applied to aggregate exfoliated clay tubules and cellulose using polyethylene glycol as an intermediate. The synthesized CCB was modified in the presence of NaOH at high temperature to obtain negative surface charge on the adsorbent. Physico-chemical properties of CCB were evaluated using different characterization techniques including Fourier transform infrared (FT-IR) and X-ra...

Abstract Carbon-based materials with a controlled pore size distribution are highly desirable to achieve fast diffusion of electrolytes and enhance supercapacitor performance. Here, we report a method to effectively control porosity of the phenol formaldehyde (PF) resin-based carbons along with pore volume and pore size distribution using a combined metal templating and physical/chemical activation approach. The combined metal templating and physical/chemical activation approach allows the preci...

Abstract Although miniaturized energy storage devices have emerging applications in portable and highly integrated electronic circuits, it is still challenging to develop fast and low-cost techniques to fabricate such micro-devices at an industrial scale. In this work, we report a novel, fast and environment-friendly photo-reduction technique to fabricate interdigitated graphene-based microelectrode patterns for in-plane microsupercapacitors (rG-O MSCs). Further selective electrodeposition of Co...

A graphene aerogel (GA) with a three-dimensional (3D) structure, ultra-lightweight nature, and high hydrophobicity was simply fabricated by the one-step pyrolysis of glucose and ammonium chloride. The as-synthesized GA exhibited a 3D interconnected microporous architecture with a high surface area of ~2860 m2∙g–1 and pore volume of 2.24 cm3∙g–1. The hydrophobic GA (10 mg∙100 mL–1) demonstrated rapid and excellent adsorption performance for the removal of food toxins such as various biogenic amin...

Visible-light-driven photocatalysts prepared using renewable resources are crucial but challenging to develop for the efficient degradation of organic pollutants, which is required to solve ever-increasing water deterioration issues. In this study, we report a visible-light-responsive photocatalyst for the efficient degradation of methylene blue (MB) as a model pollutant dye. Green-emissive carbon quantum dots (CQDs) were synthesized from pear juice via a facile, scalable, one-pot solvothermal p...

Nitrogen-doped soluble graphene nanosheets (N-wsGNSs) were synthesized using lentil as a natural source of carbon and nitrogen via a simple pyrolysis and oxidation approach. The as-synthesized N-wsGNSs showed remarkable fluorescence emission over the entire visible range, attributed to the high degree of surface passivation due to the introduction of oxygenated functional groups and heteroatom doping. The significant prospect of this approach is to use N-wsGNSs as multifunctional materials for p...

A new discrete bis-dithiolene complex, [PPh4]2[Zn(DMED)2] (1; DMED = 1,2-dicarbomethoxy-1,2-dithiolate) with sulfur-based radical character was synthesized and structurally characterized. Complex 1 is stable and exhibits a square planar geometry around the zinc metal. 1 forms nanospheres through a one-pot water-induced self-assembly in a mixture of solvents (acetonitrile–water). These nanospheres were further decorated with water-soluble carbon nanotubes (wsCNTs) through hydrogen bonding between...

The utilization of a sustainable and lightweight graphene aerogel (GA), synthesized from crude biomass, as a cell growth promoter and an adsorbent for the efficient removal of histamine (HIS), a food toxicant, from the real food matrix has been explored. Due to the self-supported three-dimensional nanoporous honeycomb-like structure of the graphene framework and the high surface area, the synthesized GA achieved an 80.69 ± 0.89% removal of HIS from red wine (spiked with HIS) after just 60 min un...
