Abstract: Recent advances in the performance of perovskite solar cells (PSCs) have been strongly linked to advancements in interfacial engineering and the development of charge-selective contact. Self-assembled monolayers (SAMs) play an important role in inverted PSCs due to their distinctive and versatile ability to manipulate chemical and physical interface properties. [..] Read more

Abstract: Semiconductor CsPbBr3 (CPB) perovskite materials exhibit narrow band gap (about 2.5 eV) and possess very fast (hundreds of picoseconds) and strong free exciton luminescence (green at the nanoscale). CPB combination with ZnO microrods can further enhance photoluminescence. [..] Read more

Abstract: Paper deals with the important question of the influence of plasma treatment on the luminescence properties of the ZnO nano- and microrods especially after the annealing in air at 700 ℃. The annealing in air at 700 ℃ significantly suppresses excitonic luminescence (it is practically vanquished). [..] Read more

Abstract: Graphene oxide is a carbonaceous material that has unique physicochemical properties (specific surface area, pollution resistance, conductivity, high mechanical strength) and can be produced in large quantities with relative ease. It is a material formed by the oxidation of graphene, which can be further modified with, for example, ascorbic acid to form reduced graphene oxide (rGO), or with hydrogen peroxide to form holey graphene oxide (HGO).

Here, we report the development of a system of hybrid multilayer materials with a chiral property for light-assisted water splitting. [..] Read more

Abstract: This study demonstrates the use of needle-punched nonwoven fabrics of poplar seed fiber and polyester fiber blends in sensor applications. For this purpose, the surfaces of the produced fabrics were functionalized by coating them with silver nanowires (AgNWs). [..] Read more

Abstract: Poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate (PEDOT-PSS) nanofiber-based materials represent advanced solutions for application in wearable electronics due to their biocompatibility, lightweight, permeability and improved sensitivity related to their large surface area. Since PEDOT is a conductive polymer, the electrospinning process for manufacturing thin, flexible nonwovens made of homogeneous nanofibers is not well-studied yet. [..] Read more

Abstract: Molybdenum oxides form a large group of materials resulting from the ability of Mo to possess different formal oxidation states and local coordinations, which may give rise to mixed-valency oxides indispensable for energy storage, gas sensing, electrochromic or catalytic applications. Nanostructuring and doping molybdenum oxides with foreign elements or mixing with similar or dissimilar metal oxides may substantially advance the properties of the individual oxide, although such an approach typically requires exceptionally high temperatures, high vacuum, and high-budget equipment.
