Silicon Oxycarbide Coatings
In article number 2303079, Stefan Seeger and co‐workers present a bottom‐up synthesis of coatings consisting of silicon oxycarbide micro‐ and nanostructures following the polymer derived ceramics route. In this process, polysiloxane rods, filaments, stars, and other structures are first grown on a variety of substrates then pyrolyzed while retaining their shape. The obtained...
Silicon oxycarbide (SiOC) materials have arisen in the past few decades as a promising new class of glasses and glass‐ceramics thanks to their advantageous chemical and thermal properties. Many applications, such as ion storage, sensing, filtering, or catalysis, require materials or coatings with high surface area and might benefit from the high thermal stability of SiOC. This work reports the first...
Dynamically Shaped Stiff Nanorods
In article number 2203820, Stefan Seeger and co‐workers propose a dynamic droplet assisted growth and shaping (d‐DAGS) synthesis strategy for the one‐step synthesis and in‐situ control of the shape of nanostructures. The obtained bamboo‐shaped silicone nanorods exhibit highly‐regular and tunable structure with ultra‐high aspect ratio, present robust mechanical stiffness...
One‐dimensional silicone nanostructures, such as filaments, wires, and tubes, have attracted significant attention, owing to their remarkable application capabilities in a large range of material and surface science. However, the soft mechanical properties of silicone cause vulnerability and irregularity in the synthesized structures, which limits their applications. Herein, a simple, solvent‐free,...
Self‐cleaning materials, which are inspired and derived from natural phenomena, have gained significant scientific and commercial interest in the past decades as they are energy‐ and labor‐saving and environmentally friendly. Several technologies are developed to obtain self‐cleaning materials. The combination of superhydrophobic and photocatalytic properties enables the efficient removal of solid...
The roughness of superhydrophobic silicone nanofilaments (SNFs) is exploited to enlarge the contact area of conventional filter material. As an efficient wetting of the filter material is crucial for water treatment, the wettability of SNFs is readily modified from superhydrophobic to hydrophilic during the functionalization process. SNFs are coated on glass beads and subsequently modified with biocidal...
