The use of an abbreviated GaN growth mode on nano-patterned AGOG sapphire substrates, which utilizes a process of using 15 nm low temperature GaN buffer and bypassing etch-back and recovery processes during epitaxy, enables the growth of high-quality GaN template on nano-patterned AGOG sapphire. The GaN template grown on nano-patterned AGOG sapphire by employing abbreviated growth mode has two orders of magnitude lower threading dislocation density than that of conventional GaN template grown on planar sapphire. The use of abbreviated growth mode also leads to significant reduction in cost of the epitaxy. The growths and characteristics of InGaN quantum wells (QWs) light emitting diodes (LEDs) on both templates were compared. The InGaN QWs LEDs grown on the nano-patterned AGOG sapphire demonstrated at least a 24% enhancement of output power enhancement over that of LEDs grown on conventional GaN templates.

Abbreviated epitaxial growth mode (AGM) method for reducing cost and improving quality of LEDs and lasers

A method is disclosed for forming a single crystal relaxor based material, including the following steps: providing a seed single crystal plate, providing a first and second polycrystalline structure, bonding the top surface of the seed crystal plate to the outer surface of the first polycrystalline structure, bonding the bottom surface of the seed crystal plate to the outer surface of the second polycrystalline structure, and annealing the bonded structure.

A surgical ligaturing and restraining device for small animals comprises an elongated tubular body member (10) having a noose (28) at the front end (18) operable from the rear end (12) of the body. The body front end is fitted with a cap (20) with two holes (22) (24) through its face. The noose is formed by a flexible and elastic cable (26), one end (25) of the cable is looped around passing through the holes in the cap. Said cable end (25) is attached to the cable itself around cable middle portion by attachment means (30). The cable runs through the inside of the body and emerges substantially from the body rear end (12). The body rear end has two short longitudinally extending slots (14) (16), each slot has one extremity open to the rear end. The slots are diametrically opposite each other, dividing the tubular body into two sides (32) (34). One side (32) is made shorter than the opposite side (34 ), so as to facilitate the locking action. The device is applied by placing the noose around an object. The noose is tightened by pulling on the cable out of the body rear end. The tightened noose is locked by passing the cable through one of the slots, and wrapped around the body several times, before passing said cable through both slots, to complete the locking procedure.

Surgical ligaturing and animal restraining device

A device for restraining an avian animal, or other small animals, so as to restrict the movements of its body, while leaving its head, legs, and its rear region exposed for various treatments. The restrainer comprises a substantially flat sheet of pliable material, to which are attached a plurality of fastener members, the fastener members having fastening surfaces adapted for releasable attachment to each other, in conjunction with a pliable strap having fastening surface adapted for releasable attachment to the corresponding fastener members on the restrainer. The sheet is folded into an approximate funnel or truncated cone shape with two openings, and retained in this shape by the engagement of the releasable fastener members. It is held above the head of an animal, with the larger opening facing downwards, and rapidly placed over it until its head protrudes out of the smaller opening, the strap is then placed around the bottom or the rear of the animal, and attached at both ends to the corresponding fastener members on the restrainer. The size as well as the shape of the present restrainer are adjustable to accommodate animals of different sizes.
