  • Publication number: 20220259677
    Abstract: The present application relates to the field of cancer, particular to hypoxic tumors. It was found that hypoxia is an important driver for hypermethylation of (promoters of) tumor suppressor genes. As this hypermethylation is a stable signature that is also present in circulating tumor DNA in peripheral blood, detecting this methylation pattern is a surrogate marker for tumor hypoxia. This can be used to adapt therapy as well.

  • Patent number: 11414519
    Abstract: A process for making ortho alkoxy bisphenol monomers includes contacting an (alk-1-enyl)alkoxyphenol (type 1) with an alkoxyphenol (type 2) in the presence of an acidic catalyst. Both type of renewable phenols (type 1 and 2) can be generated from lignocellulosic biomass. The use of such alkoxy phenols as a precursor to bisphenol monomers has the potential to reduce the cost and environmental impact of structural materials, while meeting or exceeding the performance of current petroleum-derived polymers, such as thermoplastics and thermoset resins.

  • Publication number: 20220203325
    Abstract: A miniaturized, automated method for controlled printing of large arrays of nano- to femtoliter droplets by actively transporting mother droplets over hydrophilic-in-hydrophobic (“HIH”) micropatches. The technology uses single or double-plate devices where mother droplets can be actuated and HIH micropatches on one or both plates of the device where the droplets are printed. Due to the selective wettability of the hydrophilic micropatches in a hydrophobic matrix, large nano- to femtoliter droplet arrays are created when mother droplets are transported over the arrays. The parent droplets are moved by various droplet actuation principles. Also, a method using two plates placed one top another while being separated by a spacer. One plate is dedicated to confirming and guiding parent droplets by using hydrophilic patches in a hydrophobic matrix, while the other plate contains HIH arrays for printing of the droplets.

  • Patent number: 11362061
    Abstract: A method is disclosed for electrically bonding a first semiconductor component to a second semiconductor component, both components including arrays of contact areas. In one aspect, prior to bonding, layers of an intermetallic compound are formed on the contact areas of the second component. The roughness of the intermetallic layers is such that the intermetallic layers include cavities suitable for insertion of a solder material in the cavities, under the application of a bonding pressure, when the solder is at a temperature below its melting temperature. The components are aligned and bonded, while the solder material is applied between the two. Bonding takes place at a temperature below the melting temperature of the solder. The bond can be established only by the insertion of the solder into the cavities of the intermetallic layers, and without the formation of a second intermetallic layer.
