Low or zero thermal expansion porous ceramics are required for several applications. In this work near zero thermal expansion porous ceramics were fabricated by using SiC and ZrW2O8 as positive and negative thermal expansion materials, respectively, bonded by soda lime glass. The mixture of SiC, ZrW2O8 and soda lime glass was sintered by Pulsed Electric Current Sintering (PECS, or sometimes called Spark Plasma Sintering, SPS) at 700 °C. Sintered samples with ZrW2O8 particle size smaller than 25 μm have high thermal expansion coefficient, because ZrW2O8 has the reaction with soda lime glass to form Na2ZrW3O12 during sintering process. The reaction between soda lime glass and ZrW2O8 is reduced by increasing particle size of ZrW2O8. Sintered sample with ZrW2O8 particle size 45-90 μm shows near zero thermal expansion.

Accidentally, it was found that triphenylamine (TPA) from commercial sources shows ultralong yellow-green room temperature phosphorescence (RTP) like commercial carbazole, which however disappears for lab-synthesized TPA with high purity. Herein, we for the first time identify the impurity types that cause RTP of commercial TPA, which are two N , N -diphenyl-naphthylamine isomers. Due to similar molecular polarity and very trace amount (≈0.8 ‰, molar ratio), these naphthyl substituted impurities can be easily overlooked. We further show that even at an extremely low amount (1000000 : 1, mass ratio) of impurities, RTP emission is still generated, attributed to the triplet-to-triplet energy transfer mechanism. Notably, this doping strategy is also applicable to the triphenylphosphine and benzophenone host systems, of which strong RTP emission can be activated by simply doping the corresponding naphthyl substituted analogues into them. This work therefore provides a general and efficient host/guest strategy toward high performance and diverse organic RTP materials.

2D Dion-Jacobson (DJ) perovskite single crystals (PSCs) usually demonstrate better X-ray detection performance than Ruddlesden-Popper (RP) PSCs. However, the mechanism of the improved performance is still elusive. Here, by the aid of strong interactions between dimethylbiguanide (DGA) and PbI , a novel DJ-perovskitoid (DGA)PbI is designed. From the comparison of (DGA)PbI to other 2D PSCs, it is discovered that the tiniest lattice distortion and increased hydrogen bonds in the atom-scaled analysis strengthen lattice rigidity and weaken electron-phonon coupling to suppress disordered scattering of carriers, resulting in significantly improved carrier transport and stability. Therefore, high carrier mobility (78.1 cm V s ) and a pronounced sensitivity of 4869.0 µC Gy cm are achieved using (DGA)PbI , which are the best in 2D Pb-based PSC devices to date. Finally, the (DGA)PbI devices exhibit good spatial resolution in X-ray imaging and excellent long-term stability to work as a promising candidate for medical diagnostics and nondestructive determination.

Hierarchical structures are ubiquitous in both animals and plants. The coordination of the hierarchical structures and functions makes living organisms function efficiently. This explains why hierarchical metal oxide (HMO)-based micro/nanostructures have recently received huge attention as anodes for application in highly efficient lithium-ion batteries (LIBs). Indeed, hierarchy in such micro/nanostructured HMOs offers high specific surface area, stable structure, short path length, and improved higher packing density to improve the reaction kinetics and Li + /e − transport kinetics, resulting in highly enhanced rate capability and cycling stability for LIBs. This report focuses on the hierarchical design from structural, morphological, porous, and component levels to engineer the HMOs as anodes for LIBs. The advantages of micro/nanostructured HMO-based on three reaction mechanisms (intercalation/deintercalation, conversion, and alloying/dealloying), important challenges ahead, and future perspectives on designing advanced electrode materials for next-generation high-performance LIBs are discussed.
