Patent number: 10408786Abstract: A distributable sampling and sensing instrument for chemical analysis of consumable foods and other agricultural products. The distributable sampling system is used to separate and concentrate the chemicals of interest obtained from samples at remote locations via thermal desorption onto a detachable target substrate that can be analyzed on-site or off-site. The volatile components adsorbed onto the target substrate can be analyzed with specific sensors (e.g., electrochemical sensors) or the assembly can be sent to a central lab and analyzed with conventional chemical instrumentation (e.g., GC-MS). This instrument provides the capability to enable chemical analysis of a wide range of chemical species of interest in a wide range of environments and conditions.Type: GrantFiled: June 7, 2017Date of Patent: September 10, 2019Assignee: Chemisensor, LLPInventors: Werner G.

Patent number: 10375835Abstract: The present invention relates to methods of treating metal surfaces to enhance adhesion or binding to substrates, and devices formed thereby. In some embodiments of the present invention, methods of achieving improved bonding strength without roughening the topography of a metal surface are provided. The metal surface obtained by this method provides strong bonding to resin layers. The bonding interface between the treated metal and the resin layer exhibits resistance to heat, moisture, and chemicals involved in post-lamination process steps, and therefore can suitably be used in the production of PCB's. Methods according to some embodiments of the present invention are especially useful in the fabrication of high density multilayer PCB's, in particular for PCB's having circuits with line/spacing of equal to and less than 10 microns. Methods according to other embodiments of the present invention are particularly useful in the coating of metal surfaces in a wide variety of applications.Type: GrantFiled: August 17, 2016Date of Patent: August 6, 2019Assignee: Atotech Deutchland GmbHInventors: Jen-Chieh Wei, Zhiming Liu, Steven Z.

Patent number: 7826250Abstract: This invention provides approaches to improve the signal to noise ratio (S/N) in electrochemical measurements (e.g., amperometry, voltammetry, etc.). In particular, a method is described wherein the faradaic current is temporally dissociated from the charging current associated with reading the charge of a redox-active species (e.g., a self-assembled monolayer (SAM)). This method, designated herein as open circuit potential amperometry (OCPA), quantitatively reads the charge of the redox species bound to (electrically coupled to) an electrode surface, while discriminating against both charging current(s) and amperometric signal(s) that arise, e.g., from diffusion-based species in solution.Type: GrantFiled: April 7, 2005Date of Patent: November 2, 2010Assignee: North Carolina State UniveristyInventors: Werner G.
