摘要： A sample carrier for in situ transmission electron microscopy (TEM) has a dielectric substrate with a conductive layer that forms a coplanar waveguide. The coplanar waveguide has a first and second leads formed by the conductive layer. The first lead is between an adjacent pair of second leads and is spaced from the second leads by a respective gap. The coplanar waveguide is configured to transmit an electrical signal to a specimen held by the sample carrier, in particular, an electrical signal having a frequency in the radio-frequency (RF) regime (3 kHz-300 GHz), for example, up to 100 GHz. The sample carrier may be mounted to a TEM sample holder, which supports the sample carrier within a vacuum chamber of the microscope and provides electrical connection between the leads of the sample carrier and an RF source external to the vacuum chamber.

摘要： A process for making a superionic conducting salt includes: combining a primary salt and an impact member, the primary salt including an ordered phase and being an ionic conductor; impacting the primary salt with the impact member; and converting the primary salt to the superionic conducting salt in response to impacting the primary salt with the impact member at a conversion temperature to make the superionic conducting salt, the conversion temperature optionally being less than a thermally activated transition temperature that thermally converts the primary salt to the superionic conducting salt in an absence of the impacting the primary salt, and the superionic conducting salt including a superionic conductive phase in a solid state at less than the thermally activated transition temperature.

摘要： An optical meter includes a force member to receive a force and a reflector disposed on the force member to receive radiation and to communicate a pressure of the radiation to the force member. The reflector includes a reflective surface, and the force member is configured to be displaced in response to receiving the force comprising the pressure. The optical meter is configured to measure a power of the radiation, an energy of the radiation, or a combination thereof based on the pressure. A process for measuring a property of radiation includes receiving radiation by the reflector, reflecting radiation from the reflective surface, communicating a pressure from the reflector to the force member, and displacing the force member.
