Borophene has undergone extensive exploration in recent years for potential applications in sensing, electronics, optoelectronics, and energy storage due to its promising properties. However, the existing synthesis methods, such as molecular beam epitaxy, chemical vapor deposition, and physical vapor deposition, are expensive and challenging to implement. Therefore, it is important to establish simple and scalable synthesis approaches for borophene nanosheets to realize their diverse applications. In this study, we utilized a mixed-solvent-based liquid phase exfoliation strategy using a solvent mixture containing 50% ethanol and 50% water for borophene nanosheet synthesis. Furthermore, we performed surface modifications of these nanosheets using arginine (Arg) molecules, leading to the formation of Arg-functionalized borophene quantum dots (B-Arg). These B-Arg quantum dots were used as a fluorescent probe for detecting folic acid (FA) in various media, including aqueous solutions, human blood serum (HBS), artificial urine (AU), and FA tablet solutions. The observed detection limits were approximately 14.91 nM, 14.22 nM, 14.32 nM, and 14.94 nM for aqueous media, HBS, AU, and FA tablets, respectively, for the linear concentration range of 0–6.66 μM.

With the progress of human civilization there has been a marked development in every aspect of mankind which on the other hand has also resulted in increased number of deaths following unnatural causes. Medico legal autopsies thereby portray not only the causes of death but also reflect the socio economic and demographic profile of that particular region. The present study was conducted at Tezpur Medical College & Hospital, Tezpur, Assam to find out the various patterns of Medico legal autopsies during the period 1st January 2019 to 31st December 2019.

Adsorption-mediated methods for environmental pollution control are suitable as they are cost-effective and easy to use. Porous materials can play an important role in adsorption studies. Herein, we synthesized a p-n heterostructure of phosphorene and metal oxide using a simple hydrothermal approach. The synthesized material is porous in nature, with a surface area of 127.44 m 2 /g and pore volume of about 1.73 nm with appreciable thermal stability. As the material is microporous, we used it for the adsorption of CO 2 gas and dye. For CO 2 adsorption, we determined the CO 2 gas uptake according to the mass balance principle of the ideal gas equation, and it was found to be about 21.478 mol/kg. We have also studied different isotherm models to check the adsorption phenomena. Moreover, for dye adsorption, we have chosen the xanthene-derived rose bengal (RB) dye, which shows a removal percentage of about 92.02%. In the case of dye adsorption, the material shows good reusability and significant adsorption up to five cycles.
