Title: Slippery liquid-infused porous surfaces having improved stability

Abstract

Methods and articles disclosed herein relate to liquid repellant surfaces having selective wetting and transport properties. An article having a repellant surface includes a substrate comprising surface features with re-entrant curvature and an immobilized layer of lubricating liquid wetting over the surface features. The surface features with re-entrant curvature can be designed to provide high repellency even after failure or removal of the immobilized layer of lubricating liquid under certain operating conditions.

  • A solar collector is described including a copper or copper alloy base and a selective solar heat energy-absorptive coating or film of improved stability to liquid water on the base. The selective film is characterized by having a solar absorptivity of 0.90 or higher, infrared emissivity no more than 0.02, and a stability such that its selectivity is not significantly reduced after contact with liquid water condensate over a prolonged, cumulative, non-continuous time in excess of 15,000 hours.
  • A method is given for making graphite or carbon bodies with impermeable surfaces. The method results in bodies covered with a first layer of at least one carbide of the group Ti, Cr, Mo, Si, and Zr and with a second layer of at least one of the elements Mo, Cr, Ti, Zr, and Si and/or of an electrically conducting combination of one of these elements with N, Be, B, Al, Si, P, or C. Various ways of depositing the first and second layers on the bodies are given. (D.L.C.)
  • This patent describes a UHF receiver which converts UHF modulated carrier signals to baseband video signals without any heterodyne or frequency conversion stages. A bandpass filter having a fixed frequency first filters the signals. A low noise amplifier amplifies the filtered signal and applies the signal through further amplification stages to a limited FM demodulator circuit. The UHF signal is directly converted to a baseband video signal. The baseband video signal is clamped by a clamping circuit before driving a monitor. Frequency stability for the receivers is at a theoretical maximum, and interference to adjacent receivers is eliminated due tomore » the absence of a local oscillator.« less
  • The laser is an internal mirror hermetically sealed design, utilizing an envelope made principally of glass. The effects of thermally produced distortion on mirror alignment are minimized by providing a thermally and electrically conductive liner in close contact with the envelope wall. Misalignment of the discharge-confining capillary tube is minimized by supporting its inner end by means of a concentric stiff but resilient spring, thus avoiding an unsupported cantilevered section of the capillary. Reliable starting even in environments where the ambient electromagnetic radiation is inadequate for gas ionization is secured by providing a radioactive source in the region of themore » anode electrode.« less
