TL;DR: This review describes recent efforts on the synthesis, dispersion and surface functionalization of the three dominating oxide nanoparticles used for photocatalytic, UV-blocking and sunscreen applications: titania, zinc oxide, and ceria.

TL;DR: A reason why the success of lightweight steels is strongly dependent on scientific achievements even though alloy development is closely related to industrial applications is provided.

TL;DR: A review on the current state of SFE calculation by computational thermodynamics for the Fe–Cr–Mn–N system is given and the application of a non-constant composition-dependent interfacial energy, бγ/ε, required to consider the effect of nitrogen on SFE in these systems is introduced.

TL;DR: This paper reviews the recent progress in the preparation of oxide-based and heteroatom-doped particles, which are functionalized with organic molecules or doped with heteroatoms, the physicochemical properties of the particles and the possibilities for their photofunctional applications as complex systems.

TL;DR: During the last few decades, much progress has been made in finding and investigating novel solid electrolytes and in using them for the preservation of the authors' environment, in particular in advanced solid state battery systems, fuel cells and sensors.

TL;DR: The synthesis, structure and properties of MoS2 and MoO2 are briefly summarized according to their applications for H2 generation and lithium ion batteries and their applications as electrocatalysts for hydrogen evolution reactions are overviewed.

TL;DR: A paper-based electrochemical biosensor array for multiplexed detection of physiologically relevant metabolic biomarkers and its electrochemical reader will enable the acquisition of high-density, statistically meaningful diagnostic information at the point of care in a rapid and cost-efficient way.

TL;DR: A class of iron alloys has been discovered in which a high density of strong interfaces can be created by heat-treatment alone, and the fact that there is an intrinsic work hardening mechanism in the structure leads to remarkable properties.

TL;DR: In this article, the formation of martensites and their stability under different thermal processing conditions were investigated by a combination of x-ray diffraction, differential scanning calorimetry, dilatometry and electron microscopy.

TL;DR: This work briefly reviews the techniques for determining the amount of hydrogen in materials and for measuring hydrogen permeation through them and a novel scanning probe technique based method is introduced.

TL;DR: Electron tomography was used to understand the interaction between focused ion beam-induced Frank loops and long dislocation structures in nanobeams of Al exhibiting special mechanical behaviour measured by on-chip deposition.

TL;DR: The microstructure is shown to approximate the recently identified ‘classic’ lath martensite structure: prior austenite grains are divided into packets, packets are subdivided into blocks, and blocks contain interleaved laths whose variants are the two Kurjumov–Sachs relations that share the same Bain axis of the transformation.

TL;DR: The results show that the 2.6 nM tuberculosis mycobacterium target sequences extracted from patients can easily be detected, and the turnaround time after the human DNA is extracted from clinical samples was approximately 1 h.

TL;DR: The results obtained revealed that the PDMS surface modification performed did not affect the material's biocompatibility, but decreased their hydrophobic character and bacterial adhesion and growth on its surface.

TL;DR: In vitro and in vivo results suggest that 7/3 PCL/PMMA scaffolds can be used for bone tissue regeneration and are suitable for osteoblast cell proliferation.

TL;DR: M-mode and mechanical interferometry image analyses identify matrix stiffness as an independent factor that instructs not only the maturation of already differentiated cardiomyocytes but also the induction and proliferation of cardiomeocytes from undifferentiated progenitors.

TL;DR: Results show that the Ti-doped barium ferrites (BFTO) exist in single phase and exhibit hexagonal plate-like structure, suggesting that the BFTO powders could be used as microwave absorbing materials with extraordinary properties.

TL;DR: This review focuses on the recent progress of several cancer theranostic strategies using mesoporous silica nanoparticles and carbon-based nanomaterials, which have been promising in cancer-specific theranostics during the past decade.

TL;DR: In vitro chondrocyte culture showed that the CS/MSN composite hydrogels indeed performed much better in supporting chondROcyte growth and maintaining chONDrocytic phenotype compared to the CS hydrogel, suggesting that theCS/MSN composites can be potentially very useful for cartilage regeneration.

TL;DR: Ce3+-activated Gd3Al5O12 garnet, effectively stabilized by Lu3+ doping, has been developed for new yellow-emitting phosphors and has a substantially red-shifted emission band that is desired for warm-white lighting.

TL;DR: The phosphor nanoplates developed in this work may be incorporated in luminescent films and find various lighting and display applications.

TL;DR: The feature of the LSP strengthening mechanism of nickel-based alloy at a high temperature is the co-working effect of the nanocrystalline surface and the residual compressive stress after thermal relaxation.

TL;DR: The processing conditions for preparing well dispersed silica–graphene nanoplatelets and GONP composites were optimized using powder and colloidal processing routes and decreased the hardness and brittleness index (BI) of the composites by ∼30 and ∼50% respectively.

TL;DR: Gelation of tannin–formaldehyde (TF) solutions was systematically investigated by changing pH and concentration of TF resin in water, resulting in an accurate and self-consistent description of these bioresource-based highly porous materials.

TL;DR: The interwoven AgNW/SWCNT structures show potential for use in optoelectronic applications as transparent electrodes and as an ITO replacement.

TL;DR: It is found that the phase transformation of austenite → ε-martensite is more effective in work hardening than that of δ- martensite → α′-Martensite.

TL;DR: The combination of Biosilicate® glass-ceramic and gelatine is attractive for producing novel scaffolds for bone tissue engineering and significantly improved the compressive strength of the scaffolds.

TL;DR: Investigation of the role of TLR3, TLR4 and TLR7 in cellular uptake of titanium dioxide NP (TiO2 NP) agglomerates and the resulting inflammatory responses to these NPs suggests that TLR 4 is involved in the uptake of TiO2 NPs and promotes the associated inflammatory responses.

TL;DR: Variation in ZnO optical bandgap occurring with Ga doping and insertion of additional zinc species has been explained by invoking two competing phenomena, namely bandgap widening and renormalization, usually observed in semiconductors with increasing carrier concentration.

TL;DR: Molecular materials are developed as an optical probe for caesium cation-containing particles with implementation based on simple spray-on reagents and a commonly available fluorescent lamp for naked-eye detection in the solid state that provides a higher spatial resolution than existing radioscopes and gamma-ray cameras.
