    摘要: A composition for hydrogen (H2) storage and generation including lithium aluminum hydride (LAIN is provided. The composition includes a mixture of LiAlH4 and a catalytic metal additive designed to tailor the kinetics of hydrogen release. The LiAlH4 and catalytic metal additive and are gently mixed together in order to physically disperse the LiAlH4 and catalyst powders without causing a detrimental chemical interaction. The hydrogen capacity of the composition is substantially not reduced or decreased (e.g., undergoes less than about 5% reduction) during the mixing process.

    摘要: Some variations provide an alkali metal or alkaline earth metal atom source (e.g., vapor cell) with a solid ionic conductor and a mixed ion-electron conductor electrode. Mixed ion-electron conductor electrodes are used as efficient sources and/or as sinks for alkali metal or alkaline earth metal atoms, thus enabling electrical control over metal atom content in the vapor cell. Some variations provide a vapor-cell system comprising: a vapor-cell region configured to allow a vapor-cell optical path into a vapor-cell vapor phase; a first electrode containing an mixed ion-electron conductor that is conductive for an ion of at least one element selected from Rb, Cs, Na, K, or Sr; a second electrode electrically isolated from the first electrode; and an ion-conducting layer between the first electrode and the second electrode. The ion-conducting layer is ionically conductive for at least one ionic species selected from Rb+, Cs+, Na+, K+, or Sr2+.

    摘要: Some variations provide an alkali metal or alkaline earth metal vapor cell with a solid ionic conductor and intercalable-compound electrodes. The intercalable-compound electrodes are used as efficient sources and/or as sinks for alkali metal or alkaline earth metal atoms, thus enabling electrical control over metal atom content in the vapor cell. Some variations provide a vapor-cell system comprising: a vapor-cell region configured to allow a vapor-cell optical path into a vapor-cell vapor phase; a first electrode; a second electrode electrically isolated from the first electrode, wherein the second electrode contains an intercalable compound intercalated by an element selected from Rb, Cs, Na, K, or Sr; and an ion-conducting layer between the first electrode and the second electrode. The ion-conducting layer is ionically conductive for at least one ionic species selected from Rb+, Cs+, Na+, K+, or Sr2+. The intercalable compound is preferably a carbonaceous material, such as graphite.

    摘要: Some variations provide a multiphase polymer composition comprising a first polymer material and a second polymer material that are chemically distinct, wherein the first polymer material and the second polymer material are microphase-separated on a microphase-separation length scale from about 0.1 microns to about 500 microns, wherein the multiphase polymer composition comprises first solid functional particles selectively dispersed within the first polymer material, and wherein the first solid functional particles are chemically distinct from the first polymer material and the second polymer material. Some embodiments provide an anti-corrosion composition comprising first corrosion-inhibitor particles or precursors selectively dispersed within the first polymer material, wherein the multiphase polymer composition optionally further comprises second corrosion-inhibitor particles or precursors selectively dispersed within the second polymer material. These multiphase polymer compositions may be used for other applications, such as self-cleaning, self-healing, or flame-retardant coatings. Methods of making and using these multiphase polymer compositions are disclosed.
