20140084151 | Matrix Assisted Laser Desorption Ionisation Mass Spectrometry Imaging (MALDI-MSI) - A method of preparing a sample for matrix assisted laser desorption ionisation mass spectrometry imaging analysis by a two-step process. Firstly, a MALDI matrix is dusted on to the sample followed by a spray of a suitable solvent onto the dusted sample. The present method has been successfully applied to the detection and mapping of several analyte classes in latent fingermarks. Using the present two-step method, fingermark enhancement, recovery and analysis from different substrate surfaces is now possible enabling visual and chemical information to be obtained simultaneously via remote testing. | 03-27-2014 |
20130165810 | RESPIRATION MONITORING DEVICE - A respiration monitoring device configured to provide quantitative data output of respiration cycles of a human or animal. The device may be configured to output a respiration rate and/or a respiration waveform expressed as temperature verses time. The device comprises a temperature modifier to heat or cool a flow of exhaled air. This heated or cooled air then flows past a temperature sensor to determine a temperature change associated with each exhaled air cycle. | 06-27-2013 |
20120025068 | Mass Spectrometry - Matrix-assisted laser desorption/ionisation mass spectrometry imaging (MALDI-MSI) apparatus and method comprising a laser and a multimode optical fiber to deliver a laser beam to a MADLI ion source. A vibration coupling is provided at a region along the length of optical fiber to impart an oscillatory vibrational motion at the optical fibre to move the irradiation intensity maxima at the sample to increase the effective irradiation surface area. The present apparatus and method provide increased imaging sensitivity and a corresponding reduction in data acquisition times. | 02-02-2012 |
20110311591 | Antimicrobial Coating - A substrate (100) comprising a sol-gel derived coating (101). The coating, is chemically bonded to the substrate (100) and is derived from a polysiloxane to form a network of silicon-carbon and silicon-oxygen bonds. An antimicrobial is releasably captured within the network and is capable of defusing from the coating in vivo in response to introduction of a fluid into the coating. | 12-22-2011 |
20110293957 | BARRIER MATERIAL AND METHOD FOR MAKING THE SAME - The present invention relates to a biopolymer based barrier coating composition wherein said biopolymer based barrier coating composition comprises a plasticizer, a nano-sized clay and a biopolymer comprising a native starch and/or a de-graded starch and/or a chemically modified starch. The present invention also relates to a method for preparing the biopolymer based barrier coating composition as well as to a method for coating a cellulose based substrate with the biopolymer based barrier coating composition. Finally, the present invention relates to a cellulose based substrate coated with said biopolymer based barrier coating composition. | 12-01-2011 |

20090200158 | HIGH POWER IMPULSE MAGNETRON SPUTTERING VAPOUR DEPOSITION - Method and apparatus for physical vapour deposition (PVD) and in particular high power impulse magnetron sputtering (HIPIMS) deposition is described. The present apparatus and process provide for the creation of a weaker magnetic field in the region of the cathode which reduces the confinement of a significant part of the plasma near the target surface. By weakening the magnetic field in the region of the target, the deposition rate of materials at a substrate has been found to increase by a factor of 9 relative to that of conventional HIPIMS processes employing typical magnetic field strengths. | 08-13-2009 |
20090075114 | Method for the manufacture of a hard material coating on a metal substrate and a coated substrate - A method for the manufacture of a hard material protective coating on a substrate consisting of a metal or of a electrically conductive ceramic material, e.g. a coated tool for use in a machine tool, or components exposed to high temperature wherein, prior to the deposition of the hard protective material coating, the substrate is pretreated by bombardment with metal ions of at least one rare earth element thereby resulting in implantation of some of said ions into said substrate. | 03-19-2009 |
