“…The toxicity of lead is the most crucial problem to be solved. When lead builds up in our bodies, it causes serious health problems, such as headaches, irritability, reduced sensations, aggressive behavior, difficulty sleeping, and so on . Moreover, lead is even more harmful to children as it affects nerves and brain development.…”

The organic–inorganic halide perovskite solar cells (PSCs) are rapidly developed in just a few years due to its high power conversion efficiency. However, it still faces some critical issues, one of which is the presence of toxic lead (Pb2+). Recent researches show that barium (Ba2+) can partially replace the Pb2+ in perovskite structure and achieve a promising device performance because of its adequate ionic radius. However, the optimal replacement amount of Ba2+ in perovskite is still limited. Herein, the methylammonium (MA)/formamidinium (FA) mixed‐cation perovskite is used as the active layer in PSCs and Pb2+ is partially substituted with Ba2+. Compared with the pure MA system, the best device efficiency can be achieved using higher Ba2+ replacement ratio. In addition, while introducing the appropriate polymer additive, the replacement ratio can be further increased without compromise of device efficiency. Using polyethylene glycol as polymer additive, 10.0 mol% Ba‐doped MA/FA mixed‐cation PSC with an efficiency of 16.1% can be realized. It is believed that this report provides an effective strategy to fabricate high‐performance lead‐reduced PSCs.

In this study, we developed a novel sensing material fabricated using a poly(3-hexylthiophene) (P3HT)/poly(methyl methacrylate) (PMMA) blend fiber on a glass substrate. The sensing materials can easily be used for sensing toluene vapor detected from extinction spectral changes. The extinction spectra variation is noted from the absorption of volatile organic compounds in a highly specific surface area of fibrous coating. An electrospinning technique is applied to generate a nonwoven structure and uniaxial orientation by fibrous coating. The response of the uniaxially orientated fibrous film is even improved at several toluene vapor concentrations. The best detection limit of this well-aligned fibrous film is up to 200 ppm for toluene vapor.

Conductive polymers can stimulate the adhesion and proliferation of several cell types being an interesting material to be applied in the field of tissue engineering. In this application, the addition of a thermosensitive polymer has been pointed out as an attractive strategy to improve mechanical strength and to provide conformation changes at temperature close to human body temperature. The main goal of this work was to evaluate the physical–chemical properties and promotion of cell proliferation and possible application as scaffolds for tissue engineering of blends of poly(N‐vinylcaprolactam) (PNVCL) and poly(N‐vinylcaprolactam‐co‐butylacrylate) (PNVCL‐co‐ABu) with poly(3‐hexylthiophene) (P3HT). Both polymers were synthesized and their chemical structures were confirmed by Fourier Transform Infrared (FT‐IR) and nuclear magnetic resonance (NMR) analyses. The materials were processed in films form for structural characterization, impedance measurements, and thermogravimetric analysis. The in vitro biological assays were performed using the materials as electrospun mats. The FT‐IR was also used to characterize the blends. The addition of P3HT did not change thermal stability and showed low conductivity values of the blends. Comparing the in vitro behavior of the blends and the polymers it was possible to conclude that the presence of P3HT improved cytocompatibility and promoted cell proliferation.
