Two-dimensional (2D) materials have attracted tremendous interest ever since the isolation of atomically thin sheets graphene in 2004 due to specific and versatile properties these materials. However, increasing production use 2D necessitate a thorough evaluation potential impact on human health environment. Furthermore, harmonized test protocols are needed with which assess safety The Graphene Flagship project (2013-2023), funded by European Commission, addressed identification possible...
The key remaining physics design issue for the ITER tungsten (W) divertor is question of monoblock (MB) front surface shaping in high heat flux target areas actively cooled targets. Engineering tolerance specifications impose a challenging maximum radial step between toroidally adjacent MBs 0.3 mm. Assuming optical projection parallel loads, magnetic shadowing these edges required if quasi-steady state melting to be avoided under certain conditions during burning plasma operation and...
A new insight into photoinduced charge transfer processes across carbon nanotube@TiO2 interfaces has been gained based on experimental details from transient absorption spectroscopy. We show that photoinduced, interfacial hole to carboxylic acid-functionalized multiwalled nanotubes (oxMWCNTs) TiO2 results in hole-doped oxMWCNTs and reduced TiO2. The latter is inferred femto- nanosecond spectroscopy performed with oxMWCNT@TiO2 dispersions complemented investigations using methyl viologen...
Diphenylalanine is an amyloidogenic building block that can form a versatile array of supramolecular materials. Its shortcomings, however, include the uncontrolled hierarchical assembly into microtubes heterogeneous size distribution and well-known cytotoxicity. This study rationalized heterochirality as successful strategy to address both these pitfalls it provided unprotected heterochiral dipeptide self-organized homogeneous optically clear hydrogel with excellent ability sustain...
Self-assembling peptides are being applied both in the biomedical area and as building blocks nanotechnology. Their applications closely linked to their modes of self-assembly, which determine functional nanostructures that they form. This work brings together two structural elements direct nanoscale self-association divergent directions: proline a β-breaker β-structure-associated diphenylalanine motif, into single tripeptide sequence. Amino acid chirality was found resolve tension inherent...
Short peptide hydrogels are attractive biomaterials but typically suffer from limited mechanical properties. Inclusion of other nanomaterials can serve the dual purpose hydrogel reinforcement and conferring additional physicochemical properties ( e. g., self-healing, conductivity), as long they do not hamper self-assembly. In particular, nanocarbons ideal candidates, their have demonstrated great potential in nanocarbon-polymer gel for tissue engineering or drug delivery. Recently,...

The assembly of aligned carbon nanotubes (CNT) into fibers (CNTF) is a convenient approach to exploit and apply the unique physico-chemical properties CNTs in many fields. CNT functionalization has been extensively used for their implementation composites devices. However, CNTF still its infancy, due challenges associated with preservation morphology. Here, we report thorough study gas-phase fabrics using ozone that was generated situ from UV-source. By contrast liquid-based oxidation...

Abstract Organic photodetectors displaying efficient photoelectric response in the near-infrared are typically based on narrow bandgap active materials. Unfortunately, latter require complex molecular design to ensure sufficient light absorption region.

An unreported d,l-tripeptide self-assembled into gels that embedded FeII4 L4 metal-organic cages to form materials were characterized by TEM, EDX, Raman spectroscopy, rheometry, UV/Vis and NMR circular dichroism. The cage type concentration modulated gel viscoelasticity, thus the diffusion rate of molecular guests through nanostructured matrix, as gauged 19 F 1 H spectroscopy. When two different added spatially separated layers, gel-cage composite material enabled spatial segregation a...
Graphitized carbon black (GCB) has been employed for extraction of several classes analytes, due to the large surface area and unique chemistry its groups that allows extracting a wide range including polar, acidic compounds. Despite fact structurally related materials, such as graphene, found application hybrid-components in phosphoproteomics, surprisingly, GCB never used selective enrichment phosphopeptides. For this purpose, present work we prepare magnetic composite with TiO2 (mGCB@TiO2)...
Abstract Studies of macroscopic melt motion induced by fast transient power loads and the ensuing damage to plasma-facing components are critical for ITER. Based on state-of-the-art experiments, heat transfer is argued be strongly entangled with fluid dynamics. The physics model MEMOS-U code introduced.

Aerosols can act as cloud condensation nuclei and/or ice-nucleating particles (INPs), influencing properties. In particular, INPs show a variety of different and complex mechanisms when interacting with water during the freezing process. To gain fundamental understanding heterogeneous mechanisms, studies proxies for atmospheric must be performed. Graphene its derivatives offer suitable model systems soot particles, which are ubiquitous aerosols in atmosphere. this work, we present an...

We report a new synthetic approach for the preparation of small FeOx nanoparticles, formed on surface hollow N,O-doped carbon nanoshells through an "inside-out" mechanism. By control pyrolysis conditions, iron species can ex-solve from inside onto external surface, where they form stable nanoparticles. The location (endo- or exohedral) is correlated with observed switch product selectivity (from H2O2 to H2O) in electrocatalytic oxygen reduction reaction.
