Abstract: Provided is a toroidal mixed nanoparticle including a first polymer and a second polymer interacting with the first polymer. Also provided is a method for preparing the toroidal mixed nanoparticle, including mixing the first polymer and the second polymer having cleavable hydrophobic groups to form a mixed nanoparticle; and removing a portion of cleavable hydrophobic groups from the second polymer to make the second polymer charged and to form the toroidal mixed nanoparticle. Further provided is a method for delivering a drug or a bioactive agent to a subject in need thereof, including administering to the subject a pharmaceutical composition that includes the toroidal mixed nanoparticle conjugated to an effective amount of the drug or the bioactive agent, and a pharmaceutically acceptable excipient thereof.

Abstract: An integrated circuit (IC) device includes a master latch circuit having a first clock input and a data output, a slave latch circuit having a second clock input and a data input electrically coupled to the data output of the master latch circuit, and a clock circuit. The clock circuit is electrically coupled to the first clock input by a first electrical connection configured to have a first time delay between the clock circuit and the first clock input. The clock circuit is electrically coupled to the second clock input by a second electrical connection configured to have a second time delay between the clock circuit and the second clock input. The first time delay is longer than the second time delay.

Abstract: A display device includes a first substrate, a light-emitting element, a light conversion layer, and a color filter layer. The light-emitting element is disposed on the first substrate. The light conversion layer is disposed on the light-emitting element. In addition, the color filter layer is overlapped the light-emitting element and the light conversion layer.

Abstract: In an embodiment, a method includes: forming a first inter-metal dielectric (IMD) layer over a semiconductor substrate; forming a bottom electrode layer over the first IMD layer; forming a magnetic tunnel junction (MTJ) film stack over the bottom electrode layer; forming a first top electrode layer over the MTJ film stack; forming a protective mask covering a first region of the first top electrode layer, a second region of the first top electrode layer being uncovered by the protective mask; forming a second top electrode layer over the protective mask and the first top electrode layer; and patterning the second top electrode layer, the first top electrode layer, the MTJ film stack, the bottom electrode layer, and the first IMD layer with an ion beam etching (IBE) process to form a MRAM cell, where the protective mask is etched during the IBE process.

Abstract: This invention relates to a method of preparing a first alicyclic compound having a vinyl group on one alkyl ring carbon and an alkoxy, cycloalkoxy, heterocycloalkyoxy, aryloxy, or heteroaryloxy group on the same ring carbon; the method comprising reacting an aliphatic alcohol or an aromatic alcohol with a second alicyclic compound having an exo cyclic carbon-carbon double bond, wherein the non-ring olefinic carbon is substituted with a hydroxymethyl, thiomethyl, alkoxymethyl, aryloxymethyl, acyloxymethyl, alkylsulfonyloxymethyl, arylsulfonyloxymethyl, alkylsulfonylmethyl, arylsulfonylmethyl, halomethyl, or silyloxymethyl group.

Abstract: A syringe includes a barrel with a plunger movably inserted therein and a tube extends from a first end of the barrel and is in communication with a passage in the barrel. A flange extends inward from an inner periphery of the tube. A stopper is connected to the plunger and a rod extends from the plunger and through the stopper. The rod includes engaging protrusion which is engaged with the flange to prevent the plunger from being pulled back when the plunger is pushed into the barrel after injection. The rod includes a groove and the plunger can be broken at the groove.
