We report on plasmon induced optical switching of electrical conductivity in two-dimensional (2D) arrays of silver (Ag) nanoparticles encapsulated inside nanochannels of porous anodic aluminum oxide (AAO) films. The reversible switching of photoconductivity greatly enhanced by an array of closely
Malignant tumors around fracture fixation implants have been reported sporadically for many years. Recently, however, reports of sarcomatous degeneration around a standard cemented hip arthroplasty and around cobalt-chromium-bearing hip arthroplasties raise new questions of the malignant potential
BACKGROUND
Due to the wide application of engineered aluminum oxide nanoparticles and increased aluminum containing particulate matter suspending in air, exposure of human to nano-scale aluminum oxide nanoparticles (Al2O3 NPs) is becoming inevitable.
METHODS
In the present study, RNA microarray
Unbalanced charge injection is one of the major issues that hampers the efficiency of perovskite light-emitting diodes (PeLEDs). Through engineering the device structure with multiple hole transport layers (HTLs), i.e. poly (9,9-dioctyl-fluorene-co-N-(4-butylphenyl) dipheny-lamine)
OBJECTIVE
An undetermined number of patients with temporomandibular joint (TMJ) symptoms have been treated with intra-articular disc implants composed of Teflon ethylene/propylene or Teflon polytetrafluoroethylene and aluminum oxide (Proplast-Teflon; Vitek, Houston, TX). These implants have shown
OBJECTIVE
We propose a novel method of administration of antiangiogenic and antioxidant drugs, with potential clinical application in the treatment of proliferative diabetic retinopathy (PDR) and age-related macular degeneration (AMD). We suggest the encapsulation of drugs in implantable sustained
Small titanium-aluminum oxide clusters, TiAlO(y) (-) (y=1-3) and TiAl(2)O(y) (-) (y=2-3), were studied by using anion photoelectron spectroscopy. The adiabatic detachment energies of TiAlO(y) (-) (y=1-3) were estimated to be 1.11±0.05, 1.70±0.08, and 2.47±0.08eV based on their photoelectron spectra;
Charge recombination at the photoelectrode/dye/electrolyte interface decreases the energy conversion efficiency of dye-sensitized solar cells (DSSCs). To suppress charge recombination at this interface in DSSCs, an aluminum oxide (Al₂O₃) film can be deposited as an insulating metal oxide layer on
Metal oxide (MO) semiconductor thin films prepared from solution typically require multiple hours of thermal annealing to achieve optimal lattice densification, efficient charge transport, and stable device operation, presenting a major barrier to roll-to-roll manufacturing. Here, we report a highly
To evaluate the influence of different aging techniques on zirconia-composite microtensile bond strength using different surface treatments over a 5-year follow-up period.
Zirconia disks received three surface treatments: airborne-particle abrasion with 50-μm aluminum oxide particles, selective
