Abstract: A method includes assessing tumor margins and discriminating between tumor and non-tumor tissues by analyzing the compositional make-up of smoke produced during cautery resection of tissues.

Abstract: Technologies are provided for loading processor-optimized library modules into virtual machines. In some examples, when a virtual machine is to be executed on a processor, the processor may be identified based on one or more processor characteristics. After the processor is identified, one or more library modules loaded into the virtual machine may be replaced with other library modules optimized for the identified processor.

Abstract: The present technology provides an illustrative method for treating air. The method includes providing untreated air and producing an oxygen-enriched sample from the untreated air. The method further includes generating ozone in the oxygen-enriched sample to produce an ozone-enriched sample and contacting the ozone-enriched sample and a fraction of the untreated air to produce a treated sample. The fraction of the untreated sample includes a fraction removed from the untreated air when producing the oxygen-enriched sample. The method also includes removing ozone from the treated sample to form a purified sample of air.

Abstract: Technologies are generally described for devices for detection of a biofilm by a color change in a moisture-indicating substance, such as a chemical or a dye. The moisture indicating material may be supported by a substrate and sealed to keep moisture from the moisture indicating material. Alternatively, the moisture indicating material may be supported in a pouch and sealed by the pouch. The color change results from an ingress of moisture accompanying growth of a biofilm. The moisture-indicating substance may be used with indwelling or other devices to detect a biofilm. When the biofilm has sufficiently degraded the seal, an ingress of moisture and its accompanying pH may cause a color change in the moisture-indicating substance to signify the presence of the biofilm. Methods of manufacture and use of the disclosed devices are also described.

Abstract: A disassembled battery and methods for disassembling the battery are provided. Holes are formed in an enclosure of the battery and a fluid is injected into the battery to inactivate an electrolyte inside the battery. The enclosure of the battery is then cut to define strips in the enclosure that can be peeled back to expose a core inside the battery. The core can be extracted and recycled.

Abstract: Technologies are presented for growing graphene by chemical vapor deposition (CVD) on a high purity copper surface. The surface may be prepared by deposition of a high purity copper layer on a lower purity copper substrate using deposition processes such as sputtering, evaporation, electroplating, or CVD. The deposition of the high purity copper layer may be followed by a thermal treatment to facilitate grain growth. Use of the high purity copper layer in combination with the lower purity copper substrate may provide thermal expansion matching, compatibility with copper etch removal, or reduction of contamination, producing fewer graphene defects compared to direct deposition on a lower purity substrate at substantially less expense than deposition approaches using a high purity copper foil substrate.

Abstract: Techniques and systems for reclaiming metals from articles having one or more components containing or coated with copper are provided. An example technique may include providing an article having one or more components containing or coated with copper, providing a barrel disposed in a container, the container containing an electrolytic solution and a copper starting pole component, positioning a plurality of electrically conductive particles and the article within the barrel, and separating one or more copper ions from at least a portion of the article by electrolysis.

Abstract: Techniques are generally described herein for the removal of sodium tripolyphosphate from a waste liquid. Embodiments include, but are not limited to, methods, apparatuses, systems, and articles of manufacture. Other embodiments may also be disclosed and claimed. Some techniques described herein include adding a phosphate binder to the waste liquid including sodium tripolyphosphate to cause the sodium tripolyphosphate to adsorb to the phosphate binder, and aerating the waste liquid to form bubbles in the waste liquid and to cause particles of the phosphate binder having the sodium tripolyphosphate adsorbed thereto to adhere to the bubbles and rise to a top surface of the waste liquid.

Abstract: A device for storing data includes a sequence generator configured to generate a first number sequence that is a pseudorandom number sequence, a cross-correlation unit configured to produce a second number sequence that is a cross-correlation between the first number sequence and a third number sequence, and a write and read unit configured to write the second number sequence in memory and read the second number sequence from the memory, wherein the cross-correlation unit is further configured to reconstruct the third number sequence by obtaining a cross-correlation between the first number sequence and the second number sequence read from the memory.

Abstract: An oxygen sensor includes a metalloporphyrin for detecting oxygen levels. The oxygen sensors may also include a light source and a detector. The sensors are configured to measure changes in spectra in response to the redox reaction. They can detect a variety of samples for presence and changes in oxygen concentration in both solution and gaseous form.
