Abstract: A carbene-coated metal foil is produced by applying an N-heterocyclic carbene (NHC) compound to one or more surfaces of a metal foil (e.g., an electrodeposited copper foil having a surface that is smooth and non-oxidized). The NHC compound contains a matrix-reactive pendant group that includes at least one of a vinyl-, allyl-, acrylic-, methacrylic-, styrenic-, amine-, amide- and epoxy-containing moiety capable of reacting with a base polymer (e.g., a vinyl-containing resin such as a polyphenylene oxide/triallyl-isocyanurate (PPO/TAIC) composition). The NHC compound may be synthesized by, for example, reacting a halogenated imidazolium salt (e.g., 1,3-bis(4-bromo-2,6-dimethylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride) and an organostannane having a vinyl-containing moiety (e.g., tributyl(vinyl)stannane) in the presence of a palladium catalyst. In some embodiments, an enhanced substrate for a printed circuit board (PCB) is produced by laminating the carbene-coated metal foil to a substrate that includes glass fiber impregnated with the base polymer.

Abstract: Techniques are disclosed for restoring register data in a processor. In one embodiment, a method includes receiving an instruction to flush one or more general purpose registers (GPRs) in a processor. The method also includes determining history buffer entries of a history buffer to be restored to the one or more GPRs. The method includes creating a mask vector that indicates which history buffer entries will be restored to the one or more GPRs. The method further includes restoring the indicated history buffer entries to the one or more GPRs. As each indicated history buffer entry is restored, the method includes updating the mask vector to indicate which history buffer entries have been restored.

Abstract: A process of providing matrix-bonding abrasion resistant CNTs (MBARCs) includes reacting functionalized carbon nanotubes (f-CNTs) and Janus particles, wherein each of the Janus particles is a silica particle having a surface with a first portion containing a CNT-bonding functionality and a second portion containing a matrix-bonding functionality. The CNT-bonding functionality may include, for example, one or more hydroxyl groups. The matrix-bonding functionality may be, for example, selected from a group consisting of vinyl functionalities, amine functionalities, epoxy functionalities, allyl functionalities, acrylate functionalities, sulfur functionalities, isocyanate functionalities, halogen functionalities, and combinations thereof. In some embodiments, the MBARCs are processed to produce fibers that, in turn, may be blended into a polymeric resin to produce a fiber reinforced polymer composite.

Abstract: A flame-retardant aconitic acid-derived monomer, a process for forming a flame-retardant polymer, and an article of manufacture comprising a material that contains a flame-retardant aconitic acid-derived monomer are disclosed. The flame-retardant aconitic acid-derived monomer can have at least one phosphoryl or phosphonyl moiety with functional groups that can participate in a polymerization reaction, such as allyl, epoxy, or propylene carbonate functional groups. The process for forming the flame-retardant polymer can include forming an aconitic acid derivative, forming a phosphorus-based flame-retardant molecule, and reacting the aconitic acid derivative with the phosphorus-based flame-retardant molecule to form a flame-retardant aconitic acid-derived monomer, which is then polymerized. The aconitic acid derivative can be synthesized from aconitic acid obtained from a bio-based source. The material in the article of manufacture can be a resin or adhesive, and the article of manufacture can further comprise an electronic component.

Abstract: Embodiments generally relate to devices and methods for production of fibers and threads for use in electronic device manufacturing. Described here, fibers can be produced and manipulated using a dual-surfaced sizing material. The dual-surfaced sizing material has a surface which binds a fiber and a surface which binds a resin. Thus, the dual-surfaced sizing material can be left attached to the fibers without adversely affecting the resin binding in later production steps.

Abstract: Predictive monitoring of a rotational machine of a cooling apparatus is provided by integrating a predictive vibration analyzer into an electronics rack being cooled by the cooling apparatus. The integrating includes associating at least one sensor of the predictive vibration analyzer with the rotational machine of the cooling apparatus. The analyzer includes a predetermined harmonics table of one or more base operational frequencies and associated rotational speed harmonics for the rotational machine indicative of one or more rotational faults, and the predictive vibration analyzer automatically evaluates vibration of the rotational machine during operation of the machine by analyzing vibration data therefor, and automatically ascertains, based on the vibration data, and the predetermined harmonics table, whether the rotational machine is predicted to possess a rotational fault of the one or more rotational faults.

Abstract: Embodiments of the present invention provide moisture measuring systems and methods. According to one embodiment of the present invention, a sealable compartment is used in which a specimen containing liquid can be inserted, such that all of the specimen is contained within the compartment. The relative humidity in the compartment is measured over a duration of time, which can be used to calculate the amount of liquid leaked by the specimen. Embodiments of the present invention can be utilized, for example, to calculate the leakage rate of water-carrying hardware of a cooling system, without having to create a membrane or other isolated sample of materials.
