Although this situation can be improved by utilizing ionic electroactive polymers, additional burdens may also arise from the pursuit of proper additives and their introduction into existing device fabri- cation procedures. Thermal and moisture actuations often rely on the swell and shrink of active materials during variations of tem- perature or humidity, and their performance can be further enhanced by...

Straining induces movements and segmentations of tube aggregates with tube mobility ranging at 0.1e90 nm/s.. Intertube barrier driven sensing mechanism is viscoelasticity related and is therefore interpreted on the basis of spring-dashpot models.. Accordingly, P r is often interpreted on the basis of tube straining which changes R and is here de fi ned as P r-CNT [3]. Movements of...

Visible-light-driven photocatalysis. The facile fabrication of g-C 3 N 4 /SnO 2 S-scheme heterojunctions for photocatalytic removal of NO under visible light is reported. are realized after 30 min of visible light irradiation upon the g-C 3 N 4 /SnO 2 heterojunction with 30% of g- C 3 N 4 addition. This study also shows that the g-C 3 N...

Nickel-cobalt sulfides Hydrothermal method Aerogel nanocomposites Supercapacitors. A three-dimensional reduced graphene oxide/nickel-cobalt sulfide (RGO/NiCo 2 S 4 ) aerogel was fabricated by an efficient and facile one-step hydrothermal approach. The NiCo 2 S 4 needle-like structure consisted of many small nanoparticles well attached to the surface of the RGO sheet. As an active electrode material for supercapacitors, the RGO/NiCo 2...

Wool-coiled bimetallic oxysul fi de MoSrOS catalyst synthesis for catalytic reduction of toxic organic pollutants and heavy metal ions. The MoSrOS reduction activities were also investigated by the reduction of Cr(VI), Rhodamine-B (RhB), Methyl orange (MO), Methylene blue (MB) and 4- nitrophenol (4-NP). Hence, the wool-coiled MoSrOS bimetal oxysulfide catalysts could be used in the detoxification of toxic organic and...

Enhanced magnetocaloric performance in nanocrystalline/amorphous Gd 3 Ni/Gd 65 Ni 35 composite microwires. Magnetocaloric effect Magnetic refrigeration. A novel class of nanocrystalline/amorphous Gd 3 Ni/Gd 65 Ni 35 composite microwires were created directly from melt-extraction through controlled solidification. Higher cooling ef fi ciency, compactness, and environmental friendliness are some of the outstanding advantages of MR tech- nology compared to CGC...

y) employed to address this variability issue and improve the overall performance of the memory device.. In addition, reliable and reproducible multiple resistance states, more specifically different low resistance states, can be achieved in bilayer devices by controlling the pro- gramming current down to 10 m A, which is in contrast to the binary states of the control devices. Furthermore,...
