  Complex chemistry of carbon nanotubes toward efficient and stable p-type doping

  Doped carbon nanotubes are essential for molecular electronic and energy devices. Here, protonic acids and lithium salts are employed as hole dopants and stabilizers, respectively, to induce thermally stable p-doped states in carbon nanotubes.

  Time gated Fourier transform spectroscopy as a technique for disentangling short- and long-lived luminescence

  Tools for characterizing materials both spectrally and temporally are important to investigate fundamental properties of materials. Here, 2D temporal-spectral maps are shown to be useful for characterizing and discriminating luminescence signals that occur on widely different timescales.

  Microscopic ordering of supercooled water on the ice basal face

  The melt growth of ice - crystallization from supercooled water - has complex anisotropic kinetics, closely related to the rich variety of snowflake crystals. Here, molecular dynamics simulations shed light on its microscopic mechanism, identifying a layer of ultralow density water at the growth interface.

  Manipulation of parity and polarization through structural distortion in light-emitting halide double perovskites

  Halide perovskites recently attracted wide attention for light emitting applications. Here, octahedral distortion in halide double perovskites Cs₂AgMCl₆, induced by the mixture of trivalent M-cations Bi³⁺, In³⁺, and Sb³⁺, gives rise to enhanced white light emissivity and longer photoluminescence lifetimes.

  The moment of initial crystallization captured on functionalized nanoparticles

  Understanding the mechanism of supercooling suppression by crystallization seeds is important for designing semiclathrate hydrates for latent heat storage materials. Here, we show that 10-30 nm cluster formation around silver nanoparticles promotes crystallization of supercooled aqueous solutions.

  Physical and chemical imaging of adhesive interfaces with soft X-rays

  Understanding adhesion mechanisms for polymer composites is challenging due to the bonded interface being buried. Here, soft X-rays are used to probe the chemical and physical nature of the interface, revealing multiscale factors that influence the adhesion mechanism and bond strength.

  Fast in-situ X-ray scattering reveals stress sensitivity of gypsum dehydration kinetics

  Understanding the dehydration of gypsum is important for fluid-triggered earthquakes, and for its use in the construction industry. Here, x-ray scattering reveals that a small elastic load substantially accelerates dehydration kinetics, and is far more effective than applying heat.
