A method for producing a cellulose product from a multi-layer cellulose blank structure, wherein the method comprises the steps; forming the multi-layer cellulose blank structure from at least a first layer of dry-formed cellulose fibres and a second layer of a cellulose fibre web structure, through arranging the at least first layer and second layer in a superimposed relationship to each other and in the superimposed relationship arranging the at least first layer and second layer in contact with each other; arranging the multi-layer cellulose blank structure in a forming mould; heating the multi-layer cellulose blank structure to a forming temperature in the range of 100 C. to 300 C., and forming the cellulose product from the multi-layer cellulose blank structure in the forming mould, by pressing the heated multi-layer cellulose blank structure with an isostatic forming pressure of at least 1 MPa, preferably 4-20 MPa, wherein the multi-layer cellulose blank structure is shaped into a two-dimensional or three-dimensional fibre composite structure having a single-layer configuration.

Methods and systems of fabrication of high resolution, high-throughput electrochemical sensing circuits on a substrate. High resolution electrochemical sensing circuits are printed by an effective additive technique to the substrate. Optionally, post-print annealing converts electrochemically inactive printed graphene into one that is electrochemically active. The printing can be by aerosol jet printing, but is not necessarily limited thereto. An example is inkjet printing and then the post-print annealing. Ink formulation would be adjusted for effectiveness with inkjet printing. Optionally biorecognition agents can be covalently bonded to the printed graphene for the purpose of electrochemical biosensing. High throughput fabrication of high-resolution graphene circuits (feature sizes in the tens of microns <50 m) for electrochemical biosensing is possible by chemical functionalization of the graphene surface with a biological agent.

A capsule for temporarily storing consumable materials can be manufactured from a composition containing a mixture of hydroypropyl-methyl-cellulose (HPMC) and cellulose nanocrystals (CNC) dissolved in a solvent containing a mixture of water and isopropyl alcohol. This composition exhibits non-Newtonian fluid dynamics and at least one layer of the composition can be deposited onto an elastomeric dipping pin for creating the capsule. Multiple layers of the composition can also be used to create a laminate capsule. The formed capsule can be removed from the dipping pin by axially extending the elastomeric dipping pin to cause radial contraction thereof and separating the formed capsule from the elastomeric dipping pin.
