Abstract: Provided herein are assays utilizing oxygen-sensitive fluorescent materials for the detection of oxygen. In particular, oxygen-sensitive fluorescent particles are provided for monitoring the oxygen consumption rate and metabolic fitness of living cells.

Abstract: A radiofrequency coil (1) for use in magnetic resonance to transmit or receive an oscillating magnetic field. The radiofrequency coil (1) comprises a plurality of conducting elements (2) connected together to form a continuous conducting path. Each conducting element (2) of the plurality of conducting elements are arranged in substantially parallel surfaces such that the area bounded by each conducting element (2) overlaps with at least 20% of the area bounded by another of the conducting elements (2) in another parallel surface.

Abstract: A heat sink clip comprises a connecting member (12), two pressing members (14) connecting to the connection member, each of the pressing members comprising a pressing portion (141) and two spring portions (142, 143) extending from opposite ends of the pressing portion, a first locking portion (144) depending from one of the spring portions of each pressing member, two operating members (16) each having spaced first and second pivot means, the second pivot means being below the first pivot means, the operating members respectively pivotably connected to the other one of the spring portions, and two second locking portions (18) respectively pivotably connected to the operating members. When the operating members are rotated downwardly, the first and second locking portions are raised, adapted for engaging with a retention frame and securing a heat sink to an electronic package.

Abstract: A clip (1) is used to attach a heat sink (2) onto a central processing unit (3). The clip includes a main body (10) and an operating body (20). The main body includes a central pressing portion (101), a pair of first and second spring arms (103, 102) extending from the pressing portion, and a first leg (104) depending from the first spring arm. Two pins (106) extend outwardly from opposite sides of a free end of the second spring arm. The operating body includes a handle (201), and a second leg (202) depending from the handle. The second leg defines an opening (212) bounded by two side walls (204). A slideway (205) is defined in an inner surface of each side wall, the slideway slidably receiving a corresponding pin therein. When the handle is pressed downwardly, the pins slide downwardly to be retained at bottoms (206) of the slideways.
