Advanced Engineering Materials, EarlyView.In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...

Advanced Engineering Materials, EarlyView.Mesoporous bioactive glass nanoparticles (MBGNs) are investigated for bone regeneration given their remarkable structural and functional properties. MBGNs are functionalized with Mn and Cu and incorporated with quercetin, a natural flavonoid exhibiting antioxidant, anti‐inflammatory, and antimicrobial properties.

Advanced Engineering Materials, EarlyView.A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.

Advanced Engineering Materials, EarlyView.A shape‐morphing, porous polyurethane film combines passive radiative cooling with folding to deliver multilevel heating‐and‐cooling control. High solar reflectance and midinfrared emissivity keep surfaces up to 3.5 °C cooler in direct sunlight, while photothermal triggering folds the film to absorb solar heat.

Influence of headphone position in pure-tone audiometry
, 2012 International audiencePure-tone audiometry (measurement of absolute thresholds using pure tones) is the main test for the diagnosis of hearing loss. It can be achieved by using either air conduction (with headphones or loudspeakers) or bone conduction ...

Advanced Functional Materials, EarlyView.Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...
