Perovskites go organic The perovskite structure accommodates many different combinations of elements, making it attractive for use in a wide variety applications. Building perovskites out only compounds is appealing because these materials tend to be flexible, fracture-resistant, and potentially easier synthesize than their inorganic counterparts. Ye et al. describe previously unknown family all-organic perovskites, which they synthesized 23 members (see the Perspective by Li Ji). are as...

Abstract Wearable bioelectronic devices are rapidly evolving towards miniaturisation and multifunctionality, with remarkable features such as flexibility comfort. However, achieving sustainable power supply for wearable is still a great challenge. Triboelectric nanogenerators (TENGs) can efficiently convert irregular, low-frequency bioenergy from the human body into electrical energy. Besides powering of bioelectronics, energy contains rich information sensing. In this conversion process,...

Calcium/calmodulin-dependent kinases play vital roles in protein phosphorylation eukaryotes, yet little is known about the process of calcium/calmodulin-dependent kinase and its role stress signal transduction plants. A novel plant-specific calcium-dependent calmodulin-binding receptor-like (GsCBRLK) has been isolated from Glycine soja. subcellular localization study using GFP fusion indicated that GsCBRLK localized plasma membrane. Binding assays demonstrated calmodulin binds to with an...

Abstract Narrow band gaps and excellent ferroelectricity are intrinsically paradoxical in ferroelectrics as the leakage current caused by an increase number of thermally excited carriers will lead to a deterioration ferroelectricity. A new molecular ferroelectric, hexane‐1,6‐diammonium pentaiodobismuth (HDA‐BiI 5 ), was now developed through gap engineering organic–inorganic hybrid materials. It features intrinsic 1.89 eV, thus represents first ferroelectric with less than 2.0 eV....

Molecular ferroelectrics are attracting tremendous interest because of their easy and environmentally friendly processing, light weight, low acoustical impedance, mechanical flexibility, which viable alternatives or supplements to conventional ceramic ferroelectrics. However, reports ceramic-like molecular that can be applied in the polycrystalline form have been scarce. Here, according "quasi-spherical theory", we successfully synthesized a ferroelectric with an m3mFmm2 type phase...

Introduction: The critical challenge for periodontitis therapy is thoroughly eliminating the dental plaque biofilm, particularly penetrating deep periodontal tissue. Regular therapeutic strategies are insufficient to penetrate without disturbing commensal microflora of oral cavity. Here, we constructed a Fe 3 O 4 magnetic nanoparticle loading minocycline (FPM NPs) biofilm physically and effectively eliminate biofilm. Methods: In order remove effectively, nanoparticles were modified with...
