A cathode and a battery including a cathode active material including a layer-structured material having a composition of xLi 2 MO 3 -(1-x)LiMeO 2 ; and a metal oxide having a perovskite structure. The cathode active material may have improved structural stability by intermixing a metal oxide having a similar crystalline structure with the layer-structured material, and thus, life and capacity characteristics of a cathode and a lithium battery including the metal oxide may be improved.

Provided are nonvolatile memory transistors and devices including the nonvolatile memory transistors. A nonvolatile memory transistor includes a channel element, a gate electrode corresponding to the channel element, a gate insulation layer between the channel element and the gate electrode, an ionic species moving layer between the gate insulation layer and the gate electrode, and a source and a drain separated from each other with respect to the channel element. A motion of an ionic species at the ionic species moving layer occurs according to a voltage applied to the gate electrode. A threshold voltage changes according to the motion of the ionic species. The nonvolatile memory transistor has a multi-level characteristic.

Methods, sensors, and systems for determining a concentration of glucose in a medium of a living animal are disclosed. Determining the glucose concentration may involve emitting excitation light from a light source to indicator molecules, generating a raw signal indicative of the amount of light received by a photodetector, purifying and normalizing the raw signal, and converting the normalized signal to a glucose concentration. The purification may involve removing noise (e.g., offset and/or distortion) from the raw signal. The purification and normalization may involve tracking the cumulative emission time that the light source has emitted the excitation light and tracking the implant time that has elapsed since the optical sensor was implanted. The purification and normalization may involve measuring the temperature of the sensor. The purification, normalization, and conversion may involve using parameters determined during manufacturing, in vitro testing, and/or in vivo testing.

Methods of forming scribe vents in a strengthened glass substrate having a compressive surface layer and an inner tension layer are provided. In one embodiment, a first and second defect is formed to partially expose the inner tension layer. A first scribe vent may be generated in a first scribing direction by translating a laser beam and a cooling jet on a surface of the strengthened glass substrate at a first scribing speed. A second scribe vent intersecting the first scribe vent may be generated in a second scribing direction by translating the laser beam and the cooling jet on the surface of the strengthened glass substrate at a second scribing speed that is greater than the first scribing speed. The defects may be perpendicular to the scribing directions. In another embodiment, the first scribe vent may be fused at an intersection location prior to generating the second scribe vent.
