摘要:
A micromechanical device having a deflectable member which contacts a stationary member. An antireflective coating is applied to portions of the micromechanical device to limit undesired reflection from the device. A passivation or lubrication layer is applied to the device to reduce stiction between the deflectable member and the stationary member. An insulator layer is utilized between the antireflective coating and the lubrication layer to prevent photoelectric-induced breakdown of the lubrication layer.
摘要:
A vacuum insulated glass unit (VIGU) comprises a first pane of a transparent material and a second pane of a transparent material. The second pane is spaced apart from the first pane to define a cavity therebetween. At least one of a spacer and an array of stand-off members is disposed between the first and second panes to maintain separation therebetween. A first adhesive layer forms at least a portion of a gas-tight connection between the first pane and the second pane. A highly hermetic coating is disposed over the adhesive layer, where the coating is an inorganic layer.
摘要:
Technologies are generally described for a membrane that may incorporate a graphene layer perforated by a plurality of nanoscale pores. The membrane may also include a gas sorbent that may be configured to contact a surface of the graphene layer. The gas sorbent may be configured to direct at least one gas adsorbed at the gas sorbent into the nanoscale pores. The nanoscale pores may have a diameter that selectively facilitates passage of a first gas compared to a second gas to separate the first gas from a fluid mixture of the two gases. The gas sorbent may increase the surface concentration of the first gas at the graphene layer. Such membranes may exhibit improved properties compared to conventional graphene and polymeric membranes for gas separations, e.g., greater selectivity, greater gas permeation rates, or the like.

Technologies are generally described for perforated graphene monolayers and membranes containing perforated graphene monolayers. An example membrane may include a graphene monolayer having a plurality of discrete pores that may be chemically perforated into the graphene monolayer. The discrete pores may be of substantially uniform pore size. The pore size may be characterized by one or more carbon vacancy defects in the graphene monolayer. The graphene monolayer may have substantially uniform pore sizes throughout. In some examples, the membrane may include a permeable substrate that contacts the graphene monolayer and which may support the graphene monolayer. Such perforated graphene monolayers, and membranes comprising such perforated graphene monolayers may exhibit improved properties compared to conventional polymeric membranes for gas separations, e.g., greater selectivity, greater gas permeation rates, or the like.

The present application is directed to a reservoir for use with a micro-electromechanical device having a first surface area to be lubricant. The reservoir comprises a solid component with a porous structure having a second surface area. The second surface area is greater than the first surface area. The reservoir also comprises a lubricant capable of reversibly reacting with either the solid component or the first surface area of the micro-electromechanical device.

Technologies are generally described for a method and system configured effective to detect a defect in a sample including graphene. An example method may include receiving a sample, where the sample may include at least some graphene and at least some defects in the graphene. The method may further include exposing the sample to a gas under sufficient reaction conditions to produce a marked sample, where the marked sample may include marks bonded to at least some of the defects. The method may further include placing the marked sample in a detector system. The method may also include detecting at least some of the marks with the detector system.
