Abstract: One or more first magnets and one or more second magnets are separated along an optical axis. A diamagnetic lens droplet is suspended in the paramagnetic medium. Strength, direction, and/or position of the one or more first and second magnets are adjusted to change the shape of the lens droplet or the position of the lens droplet along the axis. The one or more first magnets and one or more second magnets may include pairs of magnets offset from one another along axes that are perpendicular to one another and the optical axis. Pairs of intermediate magnets may be positioned between the one or more first magnets and one or more second magnets and adjust the offset of the lens droplet relative to the optical axis. An interface between layers of diamagnetic and paramagnetic fluids may be shaped by concentric ring magnets in order to implement a tunable lens.

Abstract: Photostimulated luminescence, which allows energy or data to be stored and released using electromagnetic waves as both the input and output, has attracted considerable interest in the fields of biomedical and informatics technologies, but this phenomenon is mostly limited to solid inorganic materials. Here, we report photostimulated luminescence from purely organic blend films composed of electron donor, acceptor, and trap/emitter molecules. In the films, charges are accumulated as radical ions by ultraviolet light irradiation and then extracted by near infrared light irradiation to produce visible light. Films are capable of multiple cycles (>10 times) of organic photostimulated luminescence, which was still observable from films left in the dark at room temperature for one week after excitation, and emission color could be varied by changing the trap/emitter molecules. These findings will broadly impact existing applications and provide new prospects for innovative flexible devices.

Abstract: A LiS battery includes a heterostructure deposited on a sponge of carbon nanotubes followed by annealing. The heterostructure may be performed by depositing layers of TiN and TiO2, such as TiN followed by TiO2. Following annealing, the TIN and TiO2 may be distributed substantially uniformly in the heterostructure. In some embodiments, the TiN layer has a thickness of 10 nm and the TiO2 layer has a thickness of 5 nm.

Abstract: Embodiments of the microwave amplification system are described. In an embodiment, a microwave amplification system includes a microwave amplifier that contains a paramagnetic material with an impurity. The impurity has a plurality of nuclear spin and electron spin-based energy levels. The system includes an input to receive a pumping signal which is transmitted to the microwave amplifier to cause a population inversion in the impurity and excite it to one of the nuclear spin and electron spin-based energy levels. The system further includes another input to receive an input signal to be amplified by the microwave amplifier, the input signal having a lower power than the pumping signal. Once transmitted to the microwave amplifier, the input signal is amplified by the excited state of the impurity in the microwave amplifier thereby generating an amplified signal.

Abstract: The present invention relates to a method for identifying a chemical structure of a wide variety of low molecular weight compounds using mass-to-charge ratio and collision cross section of fragment ions of an analyte compound. The analyte compound is ionized and fragmented, and the fragment ions are measured by a mass spectrometer with an ion mobility spectrometry measurement device. According to the present method, it does not depend on any compound class-specific characteristics or structural features, therefore enabling determinations of any classes of low molecular weight compounds, which does not limit to a specific compound class. The present invention comprises three methods which share a common data structure and s data processing method.

Abstract: Disclosed is a persistent luminescence emitter containing at least 70 mol % of an electron donor molecule and less than 30 mol % of an electron acceptor molecule wherein an electron transfer occurs from the electron donor molecule to the electron acceptor molecule by photo-irradiation of the persistent luminescence emitter, and after photo-irradiation of the persistent luminescence emitter stops, emission intensity decays non-exponentially.

Abstract: Low-cost and robust platforms are key for the development of next-generation 3D micro- and nanodevices. To fabricate such platforms, nanocrystalline diamond (NCD) is a highly appealing material due to its biocompatibility, robustness, and mechanical, electrical, electrochemical, and optical properties, while glass substrates with through vias are ideal interposers for 3D integration due to the excellent properties of glass. A low-cost process—free of photolithography and transfer printing—for fabricating arrays of TGVs that are sealed with suspended portions of an ultra-thin NCD film on one side is presented. These highly transparent structures may serve as a platform for the development of microwells for single-cell culture and analysis, 3D integrated devices such as microelectrodes, and quantum technologies. It is also possible to replace the NCD with silicon nitride or silicon carbide, allowing for the development of complex heterogeneous structures on a small scale.

Abstract: A method for making a plasmonic mushroom array includes: forming a plurality of metal nano-islands each having nanometer-range dimensions on a surface of a glass substrate; and subjecting to the glass substrate having the plurality of metal nano-islands formed thereon to reactive ion etching such that the plurality of metal nano-islands are converted to a plurality of mushroom-shaped structures each having a metal cap supported by a pillar made of a material of the glass substrate and each having dimensions smaller than the dimensions of the nano-islands, the plurality of mushroom-shaped structures being arranged in a substantially regular pattern with intervals smaller than average intervals between the nano-islands, thereby forming the plurality of nano-scale mushroom-shaped structures on the glass substrate that can exhibit localized surface plasmon resonance.

Abstract: A method for fabricating a perovskite film includes the steps of: placing a substrate on a substrate stage in a chamber, the substrate stage configured to rotate around its central axis at a rotation speed; depositing first source materials on the substrate from a first set of evaporation units, each coupled to the side section or the bottom section of the chamber; depositing second source materials on the substrate from a second set of evaporation units coupled to the bottom section, wherein the chamber includes a shield defining two or more zones having respective horizontal cross-sectional areas, which are open and facing the substrate, designated for the two or more evaporation units in the second set. The perovskite film includes multiple unit layers each being formed by one rotation of the substrate stage, and having composition and thickness thereof controlled by adjusting evaporation rates, rotation speed and horizontal cross-sectional areas.
