Abstract: This disclosure provides systems, methods, and apparatus related to thermal energy storage with phase change materials having an adjustable transition temperature. In one aspect, a method includes providing a device. The devices includes a phase change material, a salt dissolved in the phase change material, and an anode and a cathode disposed in the phase change material. The phase change material changes from a solid to a liquid at a first temperature when the salt is dissolved in the phase change material. A voltage is applied to the anode and the cathode to substantially remove the salt from the phase change material. The phase change material changes from the solid to the liquid at a second temperature when the salt is substantially removed from the phase change material, with the first temperature being a lower temperature than the second temperature.

Abstract: This disclosure provides systems, methods, and apparatus related to surface doping of nanostructures. In one aspect a plurality of nanostructures is fabricated with a solution-based process using a solvent. The plurality of nanostructures comprises a semiconductor. Each of the plurality of nanostructures has a surface with capping species attached to the surface. The plurality of nanostructures is mixed in the solvent with a dopant compound that includes doping species. During the mixing the capping species on the surfaces of the plurality of nanostructures are replaced by the doping species. Charge carriers are transferred between the doping species and the plurality of nanostructures.

Abstract: An approach is provided for presenting soft reminders (e.g., reminders for notes with no triggering criteria). A reminder manager receives an input, from a user, for specifying a note. The note is not associated with triggering criteria. In response to the request, the reminder manager retrieves contextual information from a device associated with the user, and causes, at least in part, presentation of a reminder of the note based, at least in part, on the contextual information.

Abstract: An approach is provided for presenting polymorphic notes in a graphical user interface. A polymorphic note manager receives a request to display a plurality of polymorphic notes on a graphical user interface of a device. In response to the request, the polymorphic note manager determines an order of the plurality of polymorphic notes according to either an associated date or, if there is no associated date, a creation date corresponding to each of the plurality of polymorphic notes.

Abstract: An approach is provided for generating a polymorphic note. A polymorphic note manager receives a request, from a device, to generate a polymorphic note, wherein the polymorphic note includes information of a plurality of application types that is developed over a period of time. The polymorphic note manager then generates the polymorphic note in response to the request and stores the polymorphic note for access by the device.

Abstract: An approach is provided for exploring connections of a polymorphic note. A polymorphic note manager receives a request to display one or more polymorphic notes connected to a selected polymorphic note. In response to the request, the polymorphic note manager determining the one or more connected polymorphic notes and causes, at least in part, actions that result in display of the selected polymorphic note, the one or more connected polymorphic notes, corresponding connections between the selected polymorphic note and the one or more connection polymorphic notes, or a combination thereof.
