A cellulose nanocrystal composite containing a sulfuric acid group and/or a sulfo group and an anionic functional group, and supporting fine metal particles. The total amount of the sulfuric acid group and/or the sulfo group and the anionic functional group is more than 0.17 mmol/g and not more than 4.0 mmol/g. Also disclosed is a method for producing the cellulose nanocrystal composite which includes treating a cellulose material with sulfuric acid to prepare cellulose nanocrystal containing a sulfuric acid group and/or a sulfo group; subjecting the cellulose nanocrystal to a hydrophilization treatment to prepare cellulose nanocrystal containing a sulfuric acid group and/or a sulfo group and an anionic functional group; and allowing the cellulose nanocrystal to support fine metal particles.

A system and method of automated downtime scheduling and control is disclosed. A failure of at least one component of at least one bare-metal server associated with a client is detected and a first notification is transmitted to a client system associated with the client. The notification includes a request to schedule downtime. A response including a selected downtime is received from the client system and the at least one bare-metal server is transitioned to an offline state at the selected downtime. A ticket is generated in a ticketing system for repair of the bare-metal server. The ticket identifies the at least one component.

A sulfated cellulose fiber having a cellulose I crystal structure is provided. A chemically modified cellulose fiber which has a cellulose I crystal and in which some hydroxyl groups of cellulose are substituted with a substituent represented by formula (1). An amount of the substituent introduced is 0.1 mmol to 3.0 mmol per 1 g of the chemically modified cellulose fiber, and an average degree of polymerization is 350 or more. (In formula (1), M represents a monovalent to trivalent cation.) In the production of the chemically modified cellulose fiber, a cellulose fiber is treated with sulfamic acid while maintaining a cellulose fiber shape to allow sulfamic acid and a cellulose fine fiber which is a constituent of the cellulose fiber to react with each other. ##STR00001##

Phosphoethanolamine cellulose and methods of making and using it are disclosed. In particular, the invention relates to a method of producing a phosphoethanolamine cellulose biosynthetically using a BcsG phosphoethanolamine transferase for cellulose modification. Recombinant constructs encoding BcsG are described, including constructs encoding BcsG by itself or in combination with BcsE and BcsF, which increase the extent of cellulose modification and the amount of modified cellulose produced. Production of phosphoethanolamine cellulose in cell culture and derivatization of phosphoethanolamine cellulose are also described.
