Highly Porous 3D Ni-MOFs as an Efficient and Enzyme-Mimic Electrochemical Sensing Platform for Glucose in Real Samples of Sweat and Saliva in Biomedical Applications.

Nickel-based metal-organic frameworks, denoted as three-dimensional nickel trimesic acid frameworks (3D Ni-TMAF), are gaining significant attention for their application in nonenzymatic glucose sensing due to their unique properties. Ni-MOFs possess a high surface area, tunable pore structures, and excellent electrochemical activity, which makes them ideal for facilitating electron transfer and enhancing the catalytic oxidation of glucose. This research describes a new electrochemical enzyme-mimic glucose biosensor in biological solutions that utilizes 3D nanospheres Ni-TMAF created layer-by-layer on a highly porous nickel substrate.

Promotional effect of silver nanoparticle embedded Ga-Zr-codoped TiO as an alternative anode for efficient blue, green and red PHOLEDs.

Efficient blue, green and red phosphorescent OLEDs have been harvested from silver nanoparticles embedded at a glass:Ga-Zr-codoped TiO interface. The embedded silver nanoparticles at the interface removed the non productive hole current and enhanced the efficiencies. The blue emitting device (456 nm) with emissive layer Ir(fni) exhibits a maximum luminance () of 40 512 cd m (ITO - 37 623 cd m), current efficiency ( ) of 41.

Tailoring the molecular design of twisted dihydrobenzodioxin phenanthroimidazole derivatives for non-doped blue organic light-emitting devices.

Three fused polycyclic aryl fragments, namely, naphthyl, methoxynaphthyl, and pyrenyl have been used to construct blue-emissive phenanthroimidazole-functionalized target molecules, , 1-(2,3-dihydrobenzo[][1,4]dioxin-6-yl)-2-(naphthalen-1-yl)-1-phenanthro[9,10-]imidazole (1), 1-(2,3-dihydrobenzo[][1,4]dioxin-6-yl)-2-(1-methoxynaphthalen-4-yl)-1-phenanthro[9,10-]imidazole (2), and 1-(2,3-dihydrobenzo[][1,4]dioxin-6-yl)-2-(pyren-10-yl)-1-phenanthro[9,10-]imidazole (3). The up-conversion of triplets to singlets a triplet-triplet annihilation (TTA) process is dominant in these compounds due to 2 > .
