Abstract Generation of hydrogen fuel via electrochemical water splitting powered by sustainable energy, such as wind or solar is an attractive path toward the future renewable energy landscape. However, current electrolysis requires desalinated resources, eventually leading to costs and scarcity. The development cost‐effective electrocatalysts capable saline feeds directly can be evident solution. Herein, a surface reconstructed nickel‐iron layered double hydroxide (NF‐LDH) reported...
Abstract Luminescent solar concentrators (LSCs) have the potential to serve as energy-harvesting windows in buildings. Although recent advances nanotechnology led emergence of novel fluorophores such quantum dots, perovskites and others, commercialization functional glass remains immature due an insufficient power conversion efficiency. In other words, improvements alone cannot fully maximize LSCs. Here we introduce a new laminated type LSC structure where patterned low-refractive-index...
Smart biomaterials have significantly impacted human healthcare by advancing the development of medical devices designed to function within tissue, mimicking behavior natural tissues. While intelligence has evolved from inert active over past few decades, smart take this a step further making their surfaces or bulk respond based on interactions with surrounding tissues, imparting outcomes similar tissue functions. This interaction helps in creating stimuli-responsive biomaterials, which can...

The dynamic melt crystallization kinetics of polyaniline (PAni)/poly(vinylidene fluoride) (PVDF) blends different compositions has been investigated to understand the influence PAni on heterogeneous nucleation and phase transition PVDF.
The present study compared the mechanical, electrical, morphological, and piezoresistive characteristics of epoxy-based sensing nanocomposites fabricated with inclusions hybridized networks four different carbon nanomaterials (CNMs), such as nanotube (CNT), graphene, nanofiber (CNF), graphite nanoplatelet (GNP). Enhancements in elastic modulus electrical conductivity were achieved by CNT–graphene composites CNT–CNF composites, these explained morphological observations carried out...
Abstract Fabricating an electron extraction layer (EEL) with a metal doping transition oxide (TMO) in inorganic–organic hybrid perovskite solar cells (PeSCs) and organic (OSCs) is simple efficient process for enhancing photovoltaic properties. Here, the universal benefits common factors that influence both PeSCs OSCs as result of changes Al‐doped TiO 2 properties are investigated. These identified two separate mechanisms. The first involves surface smoothing films, which affects formation...
Abstract A key factor in improving semi‐transparent organic photovoltaics (ST‐OPVs) performance is achieving high light utilization efficiency (LUE). However, device can also be limited by the lack of understanding transmission and reflection within architecture, top electrode particular. Here, highly efficient ST‐OPVs are reported via rational design silver nanowire (Ag NW) electrodes 3D optical simulation. Due to its careful consideration for ST‐OPV effect Ag NW networking structure,...
Inverted structured organic solar cells (OSCs) have recently attracted attention due to their greater stability and performance above conventional OSCs.
