Abstract: Provided herein are, inter alia, methods of assaying neuronal progenitor cell populations derived from iPSCs, thereby providing for a user friendly molecular diagnostic tool for neuronal cell types, including dopaminergic neurons. The methods provided are valuable for the efficient and precise characterization of identity and functionality of iPSC-derived dopaminergic neurons prior to their clinical application such as the treatment of Parkinson's disease or Multiple Sclerosis.

Abstract: The invention relates to a method for producing sandwich construction elements for substantially load-bearing and self-supporting building parts. In one embodiment of the invention, a method is provided including a) producing at least one layer of a mechanically bonded fiber nonwoven which is impregnated with a binder based on at least one heat-curable resin system b) curing the heat-curable resin system in order to produce at least one hardened layer of the fiber nonwoven, and fixed thermally, c) bringing a heat-foamable or heat-foamed phenol resin into contact with that surface of at least one hardened layer of the fiber nonwoven which has been modified according to step b), d) possibly annealing the composite produced in a) to c), and e) curing the further binder based on at least one heat-curable resin system.

Abstract: Disclosed are compositions and methods for classifying stem cells. The disclosure provides a way to define cells using a computational analysis.

Abstract: The invention relates to thermoset-bound fiber moldings produced from fiber material based on natural and/or synthetic fibers and bound by means of a thermoset binder. To produce thermoset-bound fiber moldings which combine the good mechanical, acoustical and fire properties of phenolic-bound fiber moldings with an ideally complete absence of any odor due to phenolic resin, at least one adsorbent is embedded in the surface and/or in the interior of the fiber molding during the operation of pre- and/or end-curing the thermosetting binder.

Abstract: The invention relates to a binder mixture based on a pulverulent mix with non-thermoreactive phenolic resin and one or more thermoreactive condensation products, from the group consisting of phenolic resins, amino resins and epoxy resins, and a powder coating material or recycled powder coating material. The mixture can be used as a binder for textile nonwovens, moulding compounds, refractory materials, abrasive materials and friction materials, and also in the foundry industry.

Abstract: Fibrous shaped elements bonded with thermosetting resins comprising a plurality of fiber layers with at least two different thermosetting resins, preferably with inner fiber layers comprising phenolic resins as the bonding agent and the upper and lower outer layers comprising epoxide resins as the bonding agent.

Abstract: An extruder for the extrusion of a material composed of a mixture of substances in which an extruder screw is rotatably mounted in a feed channel of a housing for advancing the material to an outlet, of the channel whereat a screw tip is coaxially mounted on the extruder screw and is disposed with clearance in a distributor channel extending in prolongation of the feed channel to receive the material from the extruder screw and feed the material to a discharge outlet of the distributor channel. The screw tip has a discharge surface at an end thereof remote from the extruder screw, which includes a plurality of surface portions ascending generally helically in the direction of flow of the material. The surface portions can be flat or form a continuous discharge surface.

Abstract: Ethylene glycol is prepared from carbon monoxide and hydrogen under superatmospheric pressure and at an elevated temperature in the presence of a rhodium-containing catalyst together with a cobalt catalyst, the molar ratio of rhodium to cobalt being from about 20:1 to 60:1.
