Layered Defect-Filling co-Assembled Carbazole-Based SAMs Deliver 20% Organic Solar Cells and 17% Mini-Modules

Abstract Self-assembled monolayers (SAMs) are widely used as hole-transport layers (HTLs) in organic solar cells (OSCs), yet conventional single-component SAMs often form quasi-monolayers with incomplete coverage and interfacial defects that become increasingly detrimental upon d...

Evolution of the Surface Composition of Graphene Oxide Films During Laser-Induced Reduction

Graphene oxide (GO) and reduced graphene oxide (rGO) are widely studied two-dimensional carbon nanomaterials for optoelectronic devices. Because the oxygen content and degree of reduction govern the electronic structure of GO-derived films, controlling the reduction process is es...

Acceleration for Gifted Students in Inclusive Education: Finnish and Swedish Physics and Chemistry Teachers’ Experience

This exploratory survey study examines the use of accelerative practices among lower secondary physics and chemistry teachers in Finland and Sweden (N = 160), where a longstanding emphasis on educational equality and inclusion has limited attention to the needs of gifted students...
