摘要:The present invention refers to a method for the synthesis of an adsorbing material consisting of a single-phase tetravalent manganese feroxyhite (Å?-Fe (1-x) Mn x OOH), in which a percentage of 0.05 to 25% of iron atoms has been isomorphically substituted by Mn(IV) atoms. Its production takes place in a continuous two-stage flow reactor at weakly acidic conditions (pH 4-7) and high redox (300-800 mV). The material can be used for the removal of both pentavalent and trivalent arsenic as well as other heavy metals form water. More specifically, its adsorption capacity and selectivity depending on the trivalent and pentavalent arsenic water content, are determined by the manganese percentage and the compact or hollow morphology of its structural unit which can be both controlled by the parameters of the synthesis procedure.

摘要:The invention provides methods for the synthesis of iron oxide nanoparticles and the particles obtainable by these methods. The particles can be used as tracer materials for magnetic particle imaging and for Magnetic Particle Spectroscopy (MPS). The method for the synthesis of these particles comprises the steps: (i) dissolving at least one water-soluble iron salt and at least one water-soluble stabilizer in water to form a reaction batch, (ii) adding at least one base to the reaction batch to yield a pH of 10 to 13, and (iii) exposing the reaction batch to a reaction temperature T R for a defined period of time DT, wherein T R ≥ 110°C, to obtain the iron oxide nanoparticles.

摘要:Techniques are disclosed for electrochemical synthesis of rechargeable battery cathode precursor materials using a porous carbon element. The porous carbon element acts as an air cathode to reduce oxygen. Reduced oxygen species may oxidize a transition metal anode, thereby facilitating a room temperature redox reaction with transition metals, including those that are generally resistant to corrosion, such as nickel. The transition metal reaction product(s) may be further processed into rechargeable battery cathode materials without also synthesizing hazardous waste products.
