摘要： Stabilized layered lithium metal oxide cathode materials are described which include excess lithium, Ni, Mn, and at least one other metal ion. The materials comprise a layered LiMO2-type material in which M comprises a combination of Ni, Mn, and at least one other metal ion that includes less than about 6 mol % Co; and which has about 1 to 6 percent excess lithium. In one embodiment, the stabilized lithium metal oxide cathode material comprises a composition having the empirical formula xLi2MnO3·(1−x)LiNi0.5+δ/2Mn0.5−δCoδ/2O2, wherein 0

摘要： A heat transfer module can include an envelope sealed to define an internal volume that contains a working fluid and a wick disposed on an internal surface of the envelope. The wick and envelope each has a first portion extending through an evaporator region and a second portion extending through adiabatic and condenser regions. The first portion of the wick is a metal hydride. The first portion of the envelope includes a metal liner surrounding the first portion of the wick, a first diffusion barrier layer disposed between the first portion of the wick and the metal liner, and a ceramic matrix composite cladding surrounding the metal liner. The second portions of the wick and envelope each includes a refractory metal and/or stainless steel.

摘要： Spectroscopy systems require a crystal having specific properties for analyzing a spectrum of a sample, which is typically performed for measuring the presence of one element at a time. A two-dimensional (2D) crystal mount for performing simultaneous spectroscopy measurements includes a crystal holder having multiple rows of crystal mounts. Each crystal mount is positioned and orientated to physically support a crystal at a fixed position and fixed orientation relative to an optical axis. A sample provides radiation to analyzer crystals disposed in the crystal mounts, and a detector may detect radiation reflected from the analyzer crystals, for performing multiple simultaneous spectroscopy measurements.

摘要： Optical gain mediums are required for lasing devices and high intensity optical systems across a wide range of applications. A method for achieving optical gain includes an optical gain medium having colloidal quantum fountains includes providing pump radiation to the gain medium. The electrons of the colloidal quantum fountains are promoted from a valence band to an excited state in a conduction band of the colloidal quantum fountains. Seed radiation is provided to the gain medium and electrons of the quantum fountains are de-excited by the seed radiation through stimulated emission from the excited state to a lower energy state of the conduction band, thereby providing optical gain.

摘要： A secondary electron emissive layer resistant to infiltration and fouling. A barrier layer is formed by atomic layer deposition. The barrier layer may be an emissive layer and/or an interlayer. The barrier layer may form an interlayer that is a part of an electron amplifier positioned between an emissive layer and a resistive layer. The barrier layer is resistive to fluorine migration from either the emissive layer or the resistive layer.

摘要： The present disclosure relates to a flexure mechanism that includes a plurality of thin material structures, each thin material structure including a weak-link portion and a separable constraint portion. The separable constraint portion is linked to the weak-link portion and configured to stabilize the weak-link portion. Additionally, the plurality of thin material structures are stacked and secured together to form a laminar structure.

摘要： A composition includes a silicon nanoparticle having surface-attached groups, and the silicon nanoparticle is represented by the formula:
[Si]-[linker]-[terminal group].
In the formula [Si] represents the surface of the silicon nanoparticle; [terminal group] is a moiety that is configured for further reaction or is compatible with the electrolyte; and [linker] is a group linking the surface of the silicon nanoparticle to the [terminal group].
