Metal carbides have shown great promise in a wide range of applications due to their unique catalytic, electrocatalytic and magnetic properties. However, the scalable production of dispersible metal carbide nanoparticles remains a challenge. Here, we report a simple and scalable route to dispersible iron carbide (Fe3C) nanoparticles. This uses MgO…

We report the ZnO nanoparticle-templated formation of nanoporous carbon (NTC) embedded with TiO2 nanoparticles for the adsorption and photodegradation of organic pollutants in water. Small-angle X-ray scattering (SAXS) studies indicate that NTC and NTC-TiO2 exhibit two types of porosities with average pore diameters of 2.8 and 11.5?nm, while Brunauer-Emmet-Teller (BET)…

Polymer crystals that are good conductors of heat are highly desirable for thermal management applications. Although thermally conductive polymer crystals are well known, the microscopic thermal transport processes that enable these properties have been challenging to probe experimentally. We used an optical method to probe heat conduction at submicrometer length…

Cocoa butter (CB) is the preferred fat for chocolates and confections. However, for technological and economic reasons, there have been strong efforts for partially replacing it. As shea butter (SB) has become an important natural source of symmetrical stearic-rich triacylglycerols (TAG), the aim of this work was to study physical…

Structural modularity of polymer frameworks is a key advantage of covalent organic polymers, however, only C, N, O, Si, and S have found their way into their building blocks so far. Here, the toolbox available to polymer and materials chemists is expanded by one additional nonmetal, phosphorus. Starting with a…

The diffusion mechanism and growth of large-scale domains during the immersion of latex films in water have been thoroughly investigated with scattering techniques in a combination with the gravimetric method. Latex dispersions for film formation studies had identical main monomer compositions and only differ in the hydrophilic comonomers that result…

Achieving good transparency, high strength and superior extensibility simultaneously in autonomic self-healing elastomers remains challenging and fascinating. Herein, a complementary design strategy of combining densely distributed multiple hydrogen bonds (H bonds) and loosely packed spacer units in supramolecular elastomer was reported to address the inherent contradiction of robust strength and
