Abstract: The present invention discloses methods of neutralizing apatite surfaces, for example during chromatography and before protein elution.

Abstract: Disclosed are compositions and methods for regenerating or reducing the deterioration of an apatite solid surface during, or subsequent to, a chromatographic procedure for purifying a target molecule from a sample, by treating the apatite solid surface with a buffered calcium solution, followed by a phosphate buffered solution, followed by an alkaline hydroxide. The buffered calcium solution, phosphate buffered solution, and alkaline hydroxide can be applied subsequent to a bind and elute or flow through purification procedure. The methods provide an increase in resin mass and/or particle strength compared to prior methods.

Abstract: A dye-sensitized solar cell with internal microlens array includes an anodic electrode, a cathodic counter-electrode, and an electrolyte. The anodic electrode includes a porous nano-structured active metal oxide layer having a sensitizer dye adsorbed thereon. In one embodiment, a microlens array comprising a plurality of microlens elements is disposed between the electrodes, and preferably between a transparent substrate of the anodic electrode and active metal oxide layer for dispersing light incident on the substrate to the active oxide layer. In some embodiments, the microlens elements may be convex or concave in configuration. The microlens array improves solar conversion efficiency of the solar cell. A method for forming a microlens array is further provided.

Abstract: An outside mirror lighting assembly (100) and method includes a housing (108) and a first glass panel (101) where one or more light-emitting devices (107) are positioned at an edge of the first glass panel (101). Light rays from the at least one light-emitting device (107) propagate within the glass panel for illuminating its outer periphery. Words, logos, or other indicia (125) may be also be illuminated by direct or indirect light emitted into an etched area of the glass. The mirror assembly supplies a soft illuminated glow around the outer periphery and/or the indicia for providing a unique and pleasing appearance to the user.

Abstract: A vehicular mirror assembly (100) includes a first bezel (107) for housing an electrochromic (EC) glass element and a second bezel (109) for housing a spotter glass (111) element. A spotter glass heating element (113) is positioned behind the spotter glass element (111) for heating the spotter glass (111) above an ambient temperature.

Abstract: In an affinity-type purification, ligands dissociated from the stationary phase that would otherwise leach into the species being purified are captured by a second ligand that is also incorporated into the stationary phase, the second ligand exhibiting an affinity-type interaction with the dissociated first ligand with sufficient specificity to avoid the undesired retention by the second ligand of species from the liquid sample or source liquid other than the species sought to be purified in the affinity column.

Abstract: In an axial-flow preparative chromatography column that contains a piston, commonly termed an adaptor, that is lowered over the top of the resin, the ability to lower the piston in a controlled manner to minimize the chances of damage to the resin is achieved by use of an aperture either in the piston head itself or in a compound bolt that secures the upper column frit to the piston head. The aperture is closed with a removable plug during storage and use of the piston head and column. During packing of the bed, however, the plug is replaced by a graduated rod operating as a dipstick to allow the operator to determine the distance between the bottom face of the piston head and the upper surface of the column packing.
