One aspect of the present disclosure includes a turbine vane assembly comprising a vane made from ceramic matrix composite material having an outer wall extending between a leading edge and a trailing edge and between a first end and an opposing second end; an endwall made at least partially from a ceramic matrix composite material configured to engage the first end of the vane; and a retaining region including corresponding bi-cast grooves formed adjacent the first end of the vane and a receiving aperture formed in the endwall; wherein a bond is formed in the retaining region to join the vane and endwall together.

Described herein are three-dimensional (3-D) paper fluidic devices. The entire 3-D device is fabricated on a support layer formed from a single sheet of material and assembled by folding the support layer. The folded structure may be enclosed in an impermeable cover or package. Chemically sensitive particles may be disposed in the support layer for use in detecting analytes.

A dynamic support apparatus having a frame, a dynamic interface, a temperature control mechanism, and a control system. The dynamic interface is capable of changing its geometry and is disposed on the top surface of the frame. The control system is operably connected to the dynamic interface and controls the changing geometry of the dynamic interface. There is also a temperature control mechanism disposed on the top surface of the frame for maintaining a comfortable temperature and moisture environment between the apparatus and the user's body.

A method for manufacturing a shoe part includes: the first mixing step, the standing step, the second mixing step, the setting step, and the hot press forming step. The invention mainly uses the waste coffee grounds material as raw material to manufacture the shoe part. In addition to the aroma of coffee, the shoes have the functions of deodorization and dehumidification while being worn by the user, thereby achieving multiple objectives of environmentally friendly materials, low cost, strong structure and environmentally friendly after-use treatment.

A continuous casting and rolling apparatus according to one embodiment of the present invention provides: a continuous caster for generating a steel sheet; a first rolling unit associated with the continuous caster; and a second rolling unit which is spaced apart in the outlet of the first rolling unit and comprises: a rolling mill for pressing down the steel sheet; and a cutter for cutting a portion of the steel sheet, wherein the cutter is spaced from the second rolling unit by a length corresponding to the length of the steel sheet discharged in an at least discontinuous rolling mode, and may comprise a cut withdrawal unit provided between the first rolling unit and the second rolling unit. In addition, a continuous casting and rolling method according to another embodiment of the present invention is a continuous casting and rolling method in which a continuous rolling mode and a discontinuous rolling mode are switched to and from each other, and may comprise: a continuous casting step for generating a steel sheet; a rolling step for pressing down the steel sheet to a rolling mill after the continuous casting step; and a cutting step for cutting the steel sheet between the continuous casting step and the rolling step in a discontinuous rolling mode, and cutting the steel sheet with a cutter provided by being spaced apart from the rolling mill at an interval corresponding to the length of the steel sheet being cut and discharged in an at least discontinuous rolling mode.

A method of manufacturing a surgical device can include generating a first internal frame defining an internal structure of an instrument tip; covering at least a portion of the first internal frame with a first coating to define an exterior surface of the instrument tip; and generating an instrument body such that a proximal end of the instrument tip is positioned at a distal end of the instrument body. An ophthalmic surgical instrument can include an instrument body; and an instrument tip disposed at a distal end of the instrument body, the instrument tip including a first section linearly extending along a longitudinal axis of the instrument body and a second section extending obliquely from the first section, the second section being arcuately shaped; and wherein the instrument tip comprises a first internal frame and a first coating covering the first internal frame.

Incorporating hard particles in a matrix forming the surface of a member can significantly increase wear resistance. Hard particles can degrade when they come in contact with a molten matrix material releasing constituent elements. These elements can locally degrade the matrix material on solidification. Coating the hard particles to limit contact with the matrix material and introducing an alloying element proximate the hard particles improve retention of the particles in the matrix.
