Platinum (Pt)-based-nanomaterials are currently the most successful catalysts for oxygen reduction reaction (ORR) in electrochemical energy conversion devices such as fuel cells and metal-air batteries. Nonetheless, Pt have serious drawbacks, including low abundance nature, sluggish kinetics, very high costs, which limit their practical applications. Herein, we report first rationally designed nonprecious Co–Cu bimetallic metal–organic framework (MOF) using a low-temperature hydrothermal...

Abstract Copper‐based halide perovskite, as an ideal alternative to lead‐based has attracted much attention in many applications owing its earth‐abundant element, non‐toxicity, and excellent optical properties. In this report, magnetic Mn‐incorporated lead‐free copper perovskite (Cs 3 Cu 2 Br 5 ) nanocrystal (NC) is for the first time designed prepared using a one‐pot hot‐injection route, resulting new emission band at ≈540 nm accompanied with self‐trapped exciton (STE) centered ≈445 from Cs...
There is no doubt that cancer now one of the most formidable diseases in world; despite all efforts and research, common treatment routes, including chemotherapy, photodynamic therapy, photothermal suffer from different limitations terms their efficiency performance. For this reason, strategies are being explored to improve traditional drugs reported date. In study, we have redirected function these (5-fluorouracil, 5-FU) by combining it with a graphene-gold nanocomposite molar ratios has...
This article thanks to recent advancements in nanofabrication and 3-D packaging, typical Internet of Things devices can now be wirelessly controlled using millimeter-scale sensors known as Tiny devices. Since these low-power may exposed low indirect solar irradiation, we demonstrate a novel mesosuperstructured cell (MSSC) that allows flux light harvested from both its top bottom sides. Our is based on either dye-sensitized (DSSC) or perovskite (PSC). The active layer the proposed MSSCs was...
