The present disclosure relates to a method for the purification of a human IgG-CH1 domain comprising molecule using an antigen-binding protein that is capable of binding to an epitope that is comprised in the CH1 domain of each of human IgG1, human IgG2, human IgG3 and human IgG4. The disclosure further relates to the antigen-binding proteins that can be used in the method of the disclosure. The frame-work regions of the antigen-binding proteins of the invention preferably correspond to those of antibodies that naturally are devoid of light chains as may e.g. be found in camelids. The disclosure further relates to nucleic acids that encode such antigen-binding proteins, to immunoadsorbent materials that comprise such proteins, and to the uses of such immunoadsorbent materials for the purification of IgG-CH1 domain containing molecules from a variety of species.

Sub-micrometer to centimeter scale rough symmetric and asymmetric structures are incorporated onto objects (e.g. tubes and fms). Asymmetric and hierarchically structured slippery structures can be applied to a broad range of materials and shapes of surfaces for manufacturing heat exchangers, dew harvesting devices, desalination devices, de-humidifiers, distillation towers, evaporation coils, anti-cavitation coatings, etc.

The present invention provides novel ruthenium or osmium based complex structures with a unique combination of ligands comprising a Schiff-base type ligand, a N-heterocyclic carbene ligand and a CO ligand which can be prepared according to two different routes involving easily accessible starting materials and which represent excellent catalysts for hydrogenating unsaturated compounds, oligomers and polymers, in particular at unforeseeably low temperatures. ##STR00001##

A rechargeable lithium cell comprising a cathode, an anode, an optional ion-permeable membrane disposed between the anode and the cathode, a non-flammable salt-retained liquefied gas electrolyte in contact with the cathode and the anode, wherein the electrolyte contains a lithium salt dissolved in or mixed with a liquefied gas solvent having a lithium salt concentration greater than 1.0 M so that the electrolyte exhibits a vapor pressure less than 1 kPa when measured at 20° C., a vapor pressure less than 60% of the vapor pressure of the liquefied gas solvent alone, a flash point at least 20 degrees Celsius higher than a flash point of the liquefied gas solvent alone, a flash point higher than 150° C., or no flash point, wherein the liquefied gas solvent is selected from methane, fluoromethane, difluoromethane, chloromethane, dichloromethane, ethane, fluoroethane, difluoroethane, tetrafluoroethane, chloroethane, dichloroethane, tetrachloroethane, propane, fluoropropane, chloropropane, ethylene, fluoroethylene, chloroethylene, or a combination thereof.

A method for preparing photoactive perovskite materials. The method comprises the steps of: introducing a lead halide and a first solvent to a first vessel and contacting the lead halide with the first solvent to dissolve the lead halide to form a lead halide solution, introducing a Group 1 metal halide a second solvent into a second vessel and contacting the Group 1 metal halide with the second solvent to dissolve the Group 1 metal halide to form a Group 1 metal halide solution, and contacting the lead halide solution with the Group 1 metal halide solution to form a thin-film precursor ink. The method further comprises depositing the thin-film precursor ink onto a substrate, drying the thin-film precursor ink to form a thin film, annealing the thin film; and rinsing the thin film with a salt solution.

A mutant hydrolase optionally fused to a protein of interest is provided. The mutant hydrolase is capable of forming a bond with a substrate for the corresponding nonmutant (wild-type) hydrolase which is more stable than the bond formed between the wild-type hydrolase and the substrate. Substrates for hydrolases comprising one or more functional groups are also provided, as well as methods of using the mutant hydrolase and the substrates of the invention. Also provided is a fusion protein capable of forming a stable bond with a substrate and cells which express the fusion protein.
