A high-gain and low-noise negative feedback control ('feedback control') system can detect charge transfer in quantum systems at room temperatures. The feedback control system can attenuate dissipative coupling between a quantum system and its thermodynamic environment. The feedback control system can be integrated with standard commercial voltage-impedance measurement system, for example, a potentiostat. In one aspect, the feedback control system includes a plurality of electrodes that are configured to electrically couple to a sample, and a feedback mechanism coupled to a first electrode of the plurality of electrodes. The feedback mechanism is configured to detect a potential associated with the sample via the first electrode. The feedback mechanism provides a feedback signal to the sample via a second electrode of the plurality of electrodes, the feedback signal is configured to provide excitation control of the sample at a third electrode of the plurality of electrode.

Mesoscale system feedback-induced dissipation and noise suppression

Embodiments of the present disclosure provide for systems of enhancing the signal to noise ratio, methods of orienting a nanomaterial (e.g., an antibody), methods of enhancing the signal to noise ratio in a system (e.g., an assay system), and the like.

Methods and systems for orienting nanomaterials

An active microfluidic droplet generation device includes a droplet generation junction joining at least one continuous phase channel for carrying a ferrofluid, and a dispersed phase channel for carrying a dispersed phase (e.g., aqueous) flow. A miniature electropermanent magnet (EPM) upstream from the junction generates a magnetic field to modulate a flow rate of a ferrofluid in the continuous phase channel so that dispersed phase droplets are generated with volumes actively controlled on-demand and under continuous flow.

Electropermanent magnet activated microfluidic droplet size modulation

According to one aspect, the disclosure is directed to an example embodiment in which a circuit-based arrangement includes a circuit-based substrate securing a channel, with an effective width that is not limited by the Debye screening length, along a surface of the substrate. A pair of reservoirs are included in or on the substrate and configured for containing and presenting a sample having bio-molecules for delivery in the channel. A pair of electrodes electrically couple a charge in the sample to enhance ionic current flow therein (e.g., to overcome the electrolyte screening), and a sense electrode is located along the channel for sensing a characteristic of the biological sample by using the electrostatic interaction between the enhanced ionic current flow of the sample and the sense electrode. Actual detection occurs by using a charge-signal processing circuit to process the sensed charge signal and, therefrom, provide an output indicative of a signature for the bio-molecules delivered in the channel.

Electro-diffusion enhanced bio-molecule charge detection using electrostatic interaction

Improved thermionic energy converters are provided by electrodes that include a silicon carbide support structure, a tungsten adhesion layer disposed on the silicon carbide support structure, and an activation layer disposed on the tungsten adhesion layer. The activation layer is a material that lowers the electrode work function, such as BaO, SrO and/or CaO.

Low work-function, mechanically and thermally robust emitter for thermionic energy converters

A thermionic energy converter is provided that includes an anode, a cathode, where the anode is disposed opposite the cathode, and a suspension, where a first end of the suspension is connected to the cathode and a second end of the suspension is connected to the anode, where the suspension moveably supports the cathode above the anode to form a variable gap between the anode and the cathode, where the variable gap is capable of enabling a variable thermionic current between the anode and the cathode, where the thermionic converter is capable of an AC power output.

A technique for forming an encapsulated microelectromechanical system (MEMS) device includes forming an integrated circuit using a substrate, forming a barrier using the substrate, and forming a MEMS device using the substrate. The method includes encapsulating the MEMS device in a cavity. The barrier is disposed between the integrated circuit and the cavity and inhibits the integrated circuit from outgassing into the cavity. The barrier may be substantially impermeable to gas migration from the integrated circuit.

Gas-diffusion barriers for MEMS encapsulation

A method for sealing through-holes in a material via material diffusion, without the deposition of a sealant material, is disclosed. The method is well suited to the fabrication and packaging of microsystems technology-based devices and systems. In some embodiments, the method comprises forming sacrificial material release through-holes through a structural layer, removing the sacrificial material via an etch that etches the sacrificial material through the release through-holes, and sealing of the release through-holes via material diffusion.

Deposition-free sealing for micro- and nano-fabrication

A MEMS coupler and a method to form a MEMS structure having such a coupler are described. In an embodiment, a MEMS structure comprises a member and a substrate. A coupler extends through a portion of the member and connects the member with the substrate. The member is comprised of a first material and the coupler is comprised of a second material. In one embodiment, the first and second materials are substantially the same. In one embodiment, the second material is conductive and is different than the first material. In another embodiment, a method for fabricating a MEMS structure comprises first forming a member above a substrate. A coupler comprised of a conductive material is then formed to connect the member with the substrate.

Various applications are directed to a material stack having a strained active material therein. In connection with an embodiment, an active material (e.g. a semiconductor material) is at least initially and partially released from and suspended over a substrate, strained, and held in place. The release and suspension facilitates the application of strain to the semiconductor material.

Disclosed is an oscillator that relies on redundancy of similar resonators integrated on chip in order to fulfill the requirement of one single quartz resonator. The immediate benefit of that approach compared to quartz technology is the monolithic integration of the reference signal function, implying smaller devices as well as cost and power savings.
