Zeolite interconversion is a widely used strategy due to its unique advantages in the synthesis of some zeolites. By using a long-chain quaternary amine as both a structure-directing agent and porogen, we have produced superior catalysts, which we named Hybrid Zeolites, as their structures are made of building units of different zeolite types. The properties of t...
Continue readingIn order to realize both efficient and stable perovskite solar cells, designing electron transport layer (ETL) is of crucial importance to withstand constant light illumination and thermal stress while maintaining high charge extractability. Herein, commonly used SnO2 nanoparticle-based ETL for perovskite solar cells is modified by ionic-salt ammonium chloride (NH4...
Continue readingAir fabrication of efficient and stable perovskite solar cells with substantial reproducibility is of importance for commercialization of perovskite solar cells. There has been little consensus on which halide is the best selection for thin 2D perovskite layer on 3D perovskite when processing in ambient air. In this work, the influence of humidity and halide ions i...
Continue readingTechnological development is leading to an exponential growth in the implementation of sensors and actuators where the concern about environmental problems is also focusing on electronic waste (e-waste), which is composed of hazardous materials, corresponding to a large part of urban waste, and has a strong environmental impact. Therefore, more environmentally frie...
Continue readingPoly(acrylic acid-co-acrylamide-co-maleic acid) (p(AA-co-AM-co-MA)) superabsorbent polymer was synthesized from acrylic acid (AA), acrylamide (AM), and maleic acid (MA) via free radical copolymerization. Results showed the presence of maleic acid in structure of superabsorbent has the key and superior role in creating a smart superabsorbent. The structure, morpho...
Continue readingThe current investigation deals with the simple and ecological synthesis of CaO, MgO, CaTiO3, and MgTiO3 for the photocatalytic dilapidation of rhodamine B dye. CaO was procured from chicken eggshell waste by calcination process, while MgO was produced by solution combustion method using urea as a fuel source. Furthermore, CaTiO3 and MgTiO3 were synthesized throu...
Continue readingAerogels are of great interest in diverse fields including thermal insulation, environmental protection, liquid separation, electromagnetic shielding, etc. However, the development of renewable and recyclable aerogels, especially synthetic polymer-based ones, remains an enormous challenge, which seriously hinders the practical application of aerogels. Herein, utili...
Continue readingAqueous zinc-ion batteries (AZIBs) based on Zn metal anodes are promising candidates for next-generation energy storage due to their high performance, environmental friendliness, low cost, and high abundance. However, the excessive dendrite growth and continuous hydrogen evolution of Zn metal anodes in aqueous electrolytes severely deteriorate the electrochemical p...
Continue readingVery recently, MXene-based wearable hydrogels have emerged as promising candidates for epidermal sensors due to their tissue-like softness and unique electrical and mechanical properties. However, it remains a challenge to achieve MXene-based hydrogels with reliable sensing performance and prolonged service life, because MXene inevitably oxidizes in water-contain...
Continue readingThe design of additives showing strong and selective interactions with certain target surfaces is key to crystallization control in applied reactive multicomponent systems. While suitable chemical motifs can be found through semi-empirical trial-and-error procedures, bioinspired selection techniques offer a more rationally driven approach and explore a much large...
Continue readingThis work demonstrates the Perylene Diimide (PDI) based multifunctional sensor for breath-sensing and Geriatric Emergency Signalling applications fabricated by an economically viable vacuum filtration deposition technique. The deposition of PDI molecules on the flexible substrate forms a moderately conducting percolating molecular network, exhibiting superior pre...
Continue readingHydrogen peroxide (H2O2) is an important industrial chemical and also a possible energy carrier. Photocatalytic synthesis of H2O2 is an attractive alternative to the anthraquinone process, but current catalyst systems suffer from many problems including: a limited sunlight wavelength response, the need for sacrificial reagents and insufficient activity. Here we r...
Continue readingWhen an electron is removed from a conjugated polymer, such as poly(3-hexylthiophene-2,5-diyl) (P3HT), the remaining hole and associated change in the polymer backbone structure from aromatic to quinoidal are referred to as a polaron. Bipolarons are created by removing the unpaired electron from an already-oxidized polymer segment. In electrochemically-doped P3HT...
Continue readingDeveloping ion-selective membranes with anti-biofouling property and biocompatibility is highly crucial in harvesting osmotic energy in natural environments and for future biomimetic applications. However, the exploration of membranes with these properties in osmotic energy conversion remain largely unaddressed. Herein, a tough zwitterionic gradient double-networ...
Continue readingA high-performance and stable hybrid photodetector (PD) based on a monolayer MoS2/NH2 GQDs/CsPbBr3 triple junction is demonstrated in this work. The NH2 GQDs was introduced between the monolayer MoS2 and CsPbBr3 to enhance carrier transport and separation process, and optical absorption in the triple junction. The MoS2/NH2 GQDs/CsPbBr3 triple junction was charact...
