A variable pressure (up to 10 atm) powder/gas/liquid injection inductively coupled plasma system has been developed and used to produce high-quality boron nitride nanotubes (BNNTs) at continuous production rates of 35 g/h. Under suitable conditions, collapsed BN nanotubes (i.e., nanoribbons), and closed shell BN capsules (i.e., nanococoons) are also obtained. The process is adaptable to a large variety of feedstock materials.

Perovskite-like multiferroic metal-organic frameworks (MOFs) with the general formula ABX 3 were synthesized by a microwave assisted protocol, resulting in >100-fold increase in the effi ciency of synthesis. The parameters of the synthesis were used to realize control over the size and morphology of the particles formed. The evolution of magnetic and electric properties was studied as a function of particle size. Recently, attempts at utilizing photo-injected carriers and excitons have been made to overcome diffi culties in the mobility measurement of diamond, which suffers carrier freezing at deep impurity levels. This article highlights a wealth of intriguing observations by time-resolved spectroscopy that deepens the understanding of intrinsic diamond transport properties toward the realization of high-performance devices. Rasool et al. demonstrate new liquid cell architectures utilizing graphene-sealed Si or SiN cavities for in-situ electron microscopy. While previous graphene liquid cell techniques have shown graphene to be an ideal sealing layer and electron-transparent viewing window, they trap irregular geometries of liquid with unknown sample volumes. The authors' new technique allows for a leak-proof confi nement of liquids of precise volume in the tens of attoliter range while maintaining the benefi ts of graphene as a viewing window. The utility of this new cell architecture is demonstrated by imaging the dynamics of gold nanoparticles in three dimensions with atomic resolution under a transmission electron microscope.
