Single-step preparation of mono-dispersed sulfur nanoparticles for detention of copper

Shevchenko, Natalia; Steinhart, Milos; Tomšík, Elena

Application of sulfur nanoparticles results from biocompatibility, biodegradability, and non-toxicity of the shell that covers sulfur nanoparticles. However, to prepare uniform sulfur nanoparticles still remains a challenge; particularly in aqueous medium when the size of sulfur nanoparticles is not more than 20 nm. In the current work, the detailed investigation…

Probing the Nanostructure and Arrangement of Bacterial Magnetosomes by Small-Angle X-Ray Scattering

Rosenfeldt, Sabine; Riese, Cornelius N.; Mickoleit, Frank; Schüler, Dirk; Schenk, Anna S.

Magnetosomes are membrane-enveloped single-domain ferromagnetic nanoparticles enabling the navigation of magnetotactic bacteria along magnetic field lines. Strict control over each step of biomineralization generates particles of high crystallinity, strong magnetization, and remarkable uniformity in size and shape, which is particularly interesting for many biomedical and biotechnological…

Atomically precise thiolate-gold nanoclusters with well-defined structures attract attention for use in various applications. However, most of the recently reported synthetic methods rely on prolonged synthesis times (a few hours to days) in order to produce high purity materials with a single cluster size. Such extended synthesis times make these…

Niobium dioxide (NbO2) features a high theoretical capacity and an outstanding electron conductivity, which makes it a promising alternative to the commercial graphite negative electrode. However, studies on NbO2 based lithium-ion battery negative electrodes have been rarely reported. In the present work, NbO2 nanoparticles homogeneously embedded in a carbon matrix…

Tuning Pore Dimensions of Mesoporous Inorganic Films by Homopolymer Swelling

Reid, Barry; Alvarez-Fernandez, Alberto; Schmidt-Hansberg, Benjamin; Guldin, Stefan

The functionality and applications of mesoporous inorganic films are closely linked to their mesopore dimensions. For material architectures derived from a block copolymer (BCP) micelle coassembly, the pore size is typically manipulated by changing the molecular weight corresponding to the pore-forming block. However, bespoke BCP synthesis is often a costly…

Nanoporous gold is of great interest for many applications due to its three dimensional interconnected porosity at nanoscale. Among all currently use techniques to obtain nanoporous gold, dealloying is one of the most used method to create a well-controlled nanoporous morphology. Only few studies report on the creation of nanoporous…

Biomimetic Mineralized Organic–Inorganic Hybrid Macrofiber with Spider Silk-Like Supertoughness

Yu, Yadong; He, Yan; Mu, Zhao; Zhao, Yueqi; Kong, Kangren; Liu, Zhaoming; Tang, Ruikang

Spider silk fibers (SSF) have a hierarchical structure composed of proteins with highly repetitive sequences and biomineralization is sophisticated in hierarchical organic–inorganic constructions. By using inorganic hydroxyapatite (HAP) and organic polyvinyl alcohol (PVA) to simulate the rigid crystalline and flexible amorphous protein blocks of SSF, respectively, biomimetic mineralization is…

Lu, Zijie; Rébiscoul, Diane; Causse, Jeremy; le Goff, Xavier; Mollard, Nicolas; Deschanels, Xavier

Microporous ceria thin films having nanocrystallites network were synthesized by evaporation-induced self-assembly process, using P123 amphiphilic copolymer as structure-directing agent. The impact of key experimental parameters, i.e., the sol ageing, the relative humidity (RH), the thermal treatment, on the thin layer elaboration were investigated. The results show that the organization…
