Abstract:
The invention provides antagonists and agonists of dynein mediated activity, for example specific inhibitory RNAs and dominant negative cDNAs which function as antagonists of LIS1 and dynein, and compositions comprising such antagonist and agonists. Provided are also methods for treating unwanted cell proliferation of neural progenitor cells such as cancers of the CNS, including gliomas, by administering the antagonists of the invention.
Abstract:
The present disclosure is directed to charge generating compositions and methods of making the charge generating compositions. The composition may comprise one or more polymers comprising styrene units and allyl alcohol units, and one or more photoconductive particles. Electrophotographic devices employing the compositions, including methods of making the devices, are also disclosed.
Abstract:
A method for treating a metal substrate or a metallized substrate of an imaging member including providing a metal or metallized substrate of an imaging member; treating the metal or metallized substrate with a sol-gel composition comprising a rare earth metal to form a passivation layer on the metal or metallized substrate using a sol-gel process.
Abstract:
The presently disclosed embodiments relate in general to electrophotographic imaging members, such as layered photoreceptor structures, and processes for making and using the same. More particularly, the embodiments pertain to a photoreceptor additive to improve impermeability to gases and moisture so as to minimize environment variation of photoreceptor performance.

Abstract:
A composition that finds particular utility in forming a charge generating layer of an imaging member includes at least one charge generating material, at least one polymer binder and at least one oxidized polyolefin polymer or copolymer. The oxidized polyolefin is able to impart a thixotropic rheology to the composition, and also is able to act as an anti-settling and anti-sagging agent in the composition.
Abstract:
An imaging member containing a substrate, and an outer layer containing a thiophosphate, and an image forming apparatus for forming images on a recording medium including the imaging member above, a development component to apply a developer material to said charge-retentive surface to develop said electrostatic latent image to form a developed image on said charge-retentive surface; a transfer component for transferring said developed image from said charge-retentive surface to another member or a copy substrate; and a fusing member to fuse said developed image to said copy substrate.
