The recently discovered hypophosphite perovskites are promising functional materials. This contribution is devoted to the structural, thermal, dielectric, Raman and optical studies of a new hybrid organic-inorganic perovskite, [FA]Cd(H2POO)3 (FA = formamidinium, NH2CHNH2+). We also report the thermal, magnetic, dielectric and optical properties of the known perovskite [FA]Mn(H2POO)3. [FA]Cd(H2POO)3 crystallizes in a monoclinic structure, with the space group C2/c, and transforms at 190 K to another monoclinic structure, with the space group P21/n. For both compounds, the FA+ is disordered through the two-fold axis in the high-temperature (HT) phases. However, lowering of the temperature of [FA]Mn(H2POO)3 results in the complete ordering of FA+, while the organic cations still occupy two positions in [FA]Cd(H2POO)3. Raman data provide strong evidence that both FA+ cations have the same or a very similar structure and that the phase transition is triggered by an ordering of the FA+ cations. The dielectric studimperature. Furthermore, the intensity of the observed emissions decreases quickly with increasing temperature, suggesting the possible application of [FA]Mn(H2POO)3 in non-contact optical thermometry.Adenosine triphosphate has been employed as a biomolecular building block to fabricate pH and enzyme responsive compartmentalized supramolecular assemblies sequestering silver nanoparticles (AgNPs) and doxorubicin in the core and increase the therapeutic efficacy. Detailed investigations reveal that meticulous design can integrate chemical enrichment, stimuli responsiveness and targeted delivery within compartmentalized models.Mechanical creep behaviors of natural gas hydrates are of importance for understanding the mechanical instability of gas hydrate-bearing sediments on Earth. Limited by the experimental challenges, intrinsic creep mechanisms of nanocrystalline methane hydrates remain largely unknown yet at the molecular scale. Herein, using large-scale molecular dynamics simulations, mechanical creep behaviors of nanocrystalline methane hydrates are investigated. It is revealed that mechanical creep responses are greatly dictated by internal microstructures of crystalline grain size and external conditions of temperature and static stress. Interestingly, a long steady-state creep is observed in nanocrystalline methane hydrates, which can be described by a modified constitutive Bird-Dorn-Mukherjee model. Microstructural analysis shows that deformations of crystalline grains, grain boundary diffusion and grain boundary sliding collectively govern the mechanical creep behaviors of nanocrystalline methane hydrates. Furthermore, structural transformation also appears to be important in their mechanical creep behaviors. This study provides new insights into understanding the mechanical creep scenarios of gas hydrates.Two new members of highly charged Silverton archetype [NaM12O42]11- were demonstrated in the 3D POM-based frameworks Na3[NaM12O42(Ru(DMSO)3)4]·13H2O (M = Mo (1), W (2)), where the unusual icosahedron coordination of a Na+ ion incubated as a heteroatom is reported for the first time in topical POMs. Furthermore, 23Na NMR was applied to certify the interpretation of X-ray diffraction data concerning Na localization. Additionally, the porous nature of the frameworks 1 and 2 has also been investigated.Due to their broken out-of-plane inversion symmetry, Janus two-dimensional (2D) materials exhibit some exceptional and interesting physical properties and have recently attracted increasing attention. Herein, based on first-principles calculations, we propose a series of Janus 2D titanium nitride halide TiNX0.5Y0.5 (X, Y = F, Cl, or Br, and X ≠ Y) monolayers constructed from 2D ternary compounds TiNX (X = F, Cl, or Br), where the halogen atoms X or Y are located on each side of the monolayer, respectively. Our calculations confirm that the Janus monolayers are both dynamically and thermally stable. As compared with those of perfect TiNX monolayers, the band-structure changes of Janus TiNX0.5Y0.5 monolayers are very limited and the corresponding bandgaps only increase by about 0.1-0.2 eV. Meanwhile, the Janus TiNX0.5Y0.5 monolayers show remarkable out-of-plane piezoelectricity by virtue of their broken centrosymmetry. selleck The calculated out-of-plane piezoelectric coefficient d31 is as high as 0.34 pm V-1, which is larger than those of most 2D piezoelectric materials reported previously. In addition, it is found that the formation of Janus structures could effectively improve the carrier mobility. The hole mobilities along the x-direction (y-direction) of Janus TiNF0.5Cl0.5 and TiNF0.5Br0.5 monolayers reach as high as 5402 (5118) and 5538 (4135) cm2 V-1 s-1 at 300 K, respectively, which is almost twice as large as those of perfect TiNX monolayers. The giant out-of-plane piezoelectricity and high carrier mobility of Janus TiNX0.5Y0.5 monolayers suggest that these novel 2D materials could be promising for applications in electronic and piezoelectric devices.Among the many challenges in medicine, the treatment and cure of cancer remains an outstanding goal given the complexity and diversity of the disease. Nanotheranostics, the integration of therapy and diagnosis in nanoformulations, is the next generation of personalized medicine to meet the challenges in precise cancer diagnosis, rational management and effective therapy, aiming to significantly increase the survival rate and improve the life quality of cancer patients. Different from most conventional platforms with unsatisfactory theranostic capabilities, supramolecular cancer nanotheranostics have unparalleled advantages in early-stage diagnosis and personal therapy, showing promising potential in clinical translations and applications. In this review, we summarize the progress of supramolecular cancer nanotheranostics and provide guidance for designing new targeted supramolecular theranostic agents. Based on extensive state-of-the-art research, our review will provide the existing and new researchers a foundation from which to advance supramolecular cancer nanotheranostics and promote translationally clinical applications.
