  • Patent number: 10201802
    Abstract: A method of making heteroatom-doped activated carbon is described in this application. Specifically, it describes a process that utilizes liquid furfuryl-functional-group compounds as starting materials, which are then used to dissolve the heteroatom containing source compounds, before being polymerized into solids using catalysts. The polymerized solids are then carbonized and activated to make the heteroatom-doped activated carbon. Electric double-layer capacitors (EDLC) were fabricated with activated carbons doped with boron and nitrogen, and tested for performance. Also, the boron and nitrogen content in the activated carbons was confirmed by chemical analysis.

  • Publication number: 20180375093
    Abstract: A non-amorphous hard carbon material, synthesized from Furan-ring containing compounds, is described. These non-amorphous hard carbon materials have a d002 peak in their X-ray diffraction patterns, corresponding to an interlayer spacing of >3.6 ?, along with a prominent D-band peak in their Raman spectra. BET surface area values between 2 m2/gm and around 100 m2/gm can be obtained by controlling the processing parameters of temperature, time and heating rate. The higher surface area HCs—in Li-ion and Na-ion anode configurations—are capable of high charging rates up to 100C with a cycle life of up to 100C cycles. Composites of these non-amorphous hard carbons with silicon and lithium compounds are also disclosed.

  • Patent number: 9975778
    Abstract: A method is described to make a chemically activated carbon by first immersing a suitable carbonized material into a neutral aqueous solution of inorganic salts that constitutes the chemical activating agent. The carbonized material is then removed and forms a chemically loaded activatable material that is separately heated at temperatures up to 1000° C. to form the chemically activated carbon. An additional CO2 or steam activation step is implemented to increase the surface area up to ˜3000 m2/gm. The chemical activating agents are nitrate salts in aqueous solutions, and may be reused since they are not directly heated as part of the activation process. The carbonized precursor materials include naturally occurring sources of carbon, synthetic polymeric materials and petroleum based sources.

  • Patent number: 9825978
    Abstract: Lateral movement detection may be performed by employing different detection models to score logon sessions. The different detection models may be implemented by and/or utilize counts computed from historical security event data. The different detection models may include probabilistic intrusion detection models for detecting compromised behavior based on logon behavior, a sequence of security events observed during a logon session, inter-event time between security events observed during a logon session, and/or an attempt to logon using explicit credentials. Scores for each logon session that are output by the different detection models may be combined to generate a ranking score for each logon session. A list of ranked alerts may be generated based on the ranking score for each logon session to identify compromised authorized accounts and/or compromised machines. An attack graph may be automatically generated based on compromised account-machine pairs to visually display probable paths of an attacker.

  • Publication number: 20170044466
    Abstract: The present disclosure relates to cleaning compositions in general, and cleaning compositions that are well suited for use by individuals, who experience adverse health effects that may occur upon exposure to certain chemicals. This condition, characterized as multiple chemical sensitivities (MCS), makes it virtually impossible for certain individuals to use commercially available cleaning products without inducing immunological responses. The instant disclosure presents and describes protocols for the formulation and evaluation of a variety of cleaning products using a combination of 14C assay, head space analysis and screening of ingredients and products by highly sensitized individuals. The methods and compositions newly presented herein avoid causing adverse health responses in individuals and are suitable for use by any person, particularly individuals who experience MCS.

  • Publication number: 20140261673
    Abstract: Coating compositions disclosed herein include silane-based precursors that are used to form coatings through a sol-gel process including a hydrolyzed organosilane-based sol and a hydrolyzed tetraalkoxysilane-based sol. The coatings are characterized by anti-reflective, abrasion resistant, and anti-soiling properties and the tunability of those properties with respect to different glass substrates, solar cells or geographic locations of the solar panels.

  • Patent number: 8668960
    Abstract: Disclosed is a flow coating apparatus, comprising a slot that can dispense a coating material in an approximately uniform manner along a distribution blade that increases uniformity by means of surface tension and transfers the uniform flow of coating material onto an inclined substrate such as for example glass, solar panels, windows or part of an electronic display. Also disclosed is a method of flow coating a substrate using the apparatus such that the substrate is positioned correctly relative to the distribution blade, a pre-wetting step is completed where both the blade and substrate are completed wetted with a pre-wet solution prior to dispensing of the coating material onto the distribution blade from the slot and hence onto the substrate. Thereafter the substrate is removed from the distribution blade and allowed to dry, thereby forming a coating.
