Abstract Solar absorber is required to absorb most of the energy of the solar spectral irradiance.We propose a graphene-based solar absorber design with two different metasurfaces to improve this absorption and increase the efficiency of the solar absorber.The metasurfaces are selected based on their symmetrical/asymmetrical nature (O-shape and L-s

Protonic pump inhibitors (PPIs) are the most prescribed drugs for acute and maintenance therapy of gastroesophageal reflux disease, H.pylori-eradication (in association with antibacterial therapy), for ulcers prevention and cure and, recently, for prevention of NSAIDs-induced gastropathy.The high prevalence of these acid-related disorders induces a

Since Facebook was renamed Meta, a lot of attention, debate, and exploration have intensified about what the Metaverse is, how it works, and the possible ways to exploit it.It is anticipated that Metaverse will be a continuum of rapidly emerging technologies, usecases, capabilities, and experiences that will make it up for the next evolution of the

Abstract A convenient and efficient solvent-free, facile, one-pot three-component graphene oxide catalysed Medical Thermometers approach has been described for the synthesis of chromeno-[4,3-b]quinolin-6-one derivatives from 4-hydroxycoumarin with aldehydes and aromatic amines.Graphene oxide (GO) has proved to be a new class of heterogeneous carboc
