    Abstract: A resistive memory device includes a bottom electrode and a top electrode sandwiching a switching layer. The device also includes a field enhancement (FE) feature that extends from the bottom electrode either into the switching layer or is covered by switching layer and that is to enhance an electric field generated by the two electrodes to thereby confine a switching area of the device at the FE feature. The device further includes a planar interlayer dielectric surrounding the device, for supporting the top electrode. A method of making a resistive memory device, employing in-situ vacuum deposition of all layers, is also provided.

  • Patent number: 9333295
    Abstract: The disclosure provides a thermotherapy needling instrument with tissue injection, including: a casing, an outer needle, an inner needle and a working needle. The casing has an inlet, an outlet and an inner channel. The outer needle is connected to the casing, and is in communication with the inner channel. The inner needle is disposed in the inner channel of the casing and the outer needle, and the inner needle has at least one opening. The at least one opening is in communication with the inner channel so that the cooling agent flows in circulation. The working needle is connected to the outer needle so as to receive the injectant for injection and tissue ablation. By using the thermotherapy needling instrument, when sampling or injection is required during thermotherapy, the injection efficacy can be achieved by withdrawing the inner needle only. Therefore, efficacy of tissue injection and ablation thermotherapy can be achieved.

    Abstract: According to an example, methods for forming three-dimensional (3-D) nano-particle assemblies may include depositing surface-enhanced spectroscopy (SES) elements onto respective tips of nano-fingers, in which the nano-fingers are arranged in sufficiently close proximities to each other to enable the tips of groups of adjacent ones of the nano-fingers to come into sufficiently close proximities to each other to enable the SES elements on the tips to be bonded together when the nano-fingers are partially collapsed. The methods also include causing the nano-fingers to partially collapse toward adjacent ones of the nano-fingers to cause a plurality of SES elements on respective groups of the nano-fingers to be in relatively close proximities to each other and form respective clusters of SES elements, introducing additional particles that are to attach onto the clusters of SES elements, and causing the clusters of SES elements to detach from the nano-fingers.
