Worldwide chemical industries are concerned towards pollution‐free and green processes. In this regard, alternative energy resource having minimal pollutant and toxins emission would be preferred. Jatropha curcas (JCO) is one of the important and alternative feedstock for biodiesel production. In the present work, JCO with higher (5.5%) free fatty acid (FFA) was used for transesterification using K–Mg composite catalyst. It found that 1:2 ratio of K/Mg was the best combination for efficient conversion of JCO to corresponding methyl esters. Physico‐chemical characterization of this novel catalyst exhibited improved surface area with adequate porosity as well as basicity helping its exceptional catalytic activity. Under optimum condition, 99.5% conversion was achieved using 10:1 ratio of methanol to JCO for 3 h at 70°C using 6 wt% of catalyst. This catalyst was truly heterogeneous in nature and almost retained its activity for subsequent re‐using for next five batches. The developed catalyst is highly efficient and greener in terms of lesser leaching behaviour and retaining the basic catalytic sites in the course of transesterification. The fuel properties of the biodiesel are fully complied with ASTM protocols; thus, research findings are significant to fulfil the demand of biodiesel in present scenario.

Internationally emerging energy trend, depletion of existing fossil fuel reserves along with growing population and alarming pollution all together has diverted the research towards the use of renewable fuels such as biodiesel. Biodiesel being eco‐friendly and climate neutral is a better alternative to vastly depleting petrodiesel fuels. Biodiesel is frequently produced by combining vegetable oil and alcohol with catalyst in a transesterification reaction. Catalyst is a key factor that is known to affect the kinetics and output of a transesterification reaction. Moreover, one of the most critical features of a catalyst‘s catalytic activity is the particle size. The present review is an account of the widely used heterogeneous nanocatalyst for biodiesel synthesis. Heterogeneous nanocatalyst are novel for FAME synthesis as they are economical, recyclable, reusable, readily available, active, selective, non‐corrosive, stable and conveniently separable. Metal oxide (MO), Nano ferrites, Nano zeolites, Nano hydrotalcite and Metal Organic Frameworks (MOFs) based heterogeneous nanocatalyst and their reusability have been discussed. Critical factors like time duration, alcohol‐to‐oil ratio, reaction temperature, intensity of mixing, catalyst loading etc. have also been accounted in this review.

“…19 Among the candidate nanomaterials being utilized to modify electrode, graphene oxide (GO), one of the most important derivatives of graphene, exhibits fascinating properties including large surface area, ease of synthesis and good biocompatibility, 20 and contains various oxygen functional groups providing binding sites for the covalent immobilization of DNA. [21][22][23] To improve the high sheet resistance and poor electronic conductivity and enhance the electrochemical activity, various kinds of nanoparticles were used to functionalize GO, including metal oxides nanoparticles, 24 metal nanoparticles 25 and quantum dots (QDs). 26 Numerous researches based on different GObased nanocomposites used for the development of DNA biosensors have been reported in recent years, [27][28][29] which can impart special and advantageous properties to electrochemical biosensors.…”

Purpose: The PML/RARα fusion gene as a leukemogenesis plays a significant role in clinical diagnosis of the early stage of acute promyelocytic leukemia (APL). Here, we present an electrochemical biosensor for PML/RARα fusion gene detection using carbon dots functionalized graphene oxide (CDs/GO) nanocomposites modified glassy carbon electrode (CDs/GO/GCE). Materials and Methods: In this work, the CDs/GO nanocomposites are produced through π-π stacking interaction and could be prepared in large quantities by a facile and economical way. The CDs/GO nanocomposites were decorated onto electrode surface to improve the electrochemical activity and as a bio-platform attracted the target deoxyribonucleic acid (DNA) probe simultaneously. Results: The CDs/GO/GCE was fabricated successfully and exhibits high electrochemical activity, good biocompatibility, and strong bioaffinity toward the target DNA sequences, compared with only the pristine CDs on GCE or GO on GCE. The DNA biosensor displays excellent sensing performance for detecting the relevant pathogenic DNA of APL with a detection limit of 83 pM (S/N = 3). Conclusion:According to the several experimental results, we believe that the simple and economical DNA biosensor has the potential to be an effective and powerful tool for detection of pathogenic genes in the clinical diagnosis.
