A copper-coated palladium-containing particle dispersion in which copper-coated palladium-containing particles, which are obtained by coating surfaces of palladium-containing particles with copper, are dispersed is prepared, a platinum ion-containing solution is prepared, and a shell is formed by mixing the copper-coated palladium-containing particle dispersion and the platinum ion-containing solution with each other in a microreactor to displace copper of the copper-coated palladium-containing particle surfaces with platinum. The microreactor includes at least a first supply flow path, a second supply flow path, a joint portion in which the first supply flow path and the second supply flow path are joined to each other, and a discharge flow path. An orifice portion is provided midway in the discharge flow path. A pressure applied to the orifice portion in the displacement step is 2 MPa or higher.

Provided herein are compositions for preventing, ameliorating, and/or reducing tissue ischemia and/or tissue damage due to ischemia, increasing blood vessel diameter, blood flow and tissue perfusion in the presence of vascular disease including peripheral vascular disease, atherosclerotic vascular disease, coronary artery disease, stroke and influencing other conditions, by suppressing CD47 and/or blocking TSP1 and/or CD47 activity or interaction. Influencing the interaction of CD47-TSP1 in blood vessels allows for control of blood vessel diameter and blood flow, and permits modification of blood pressure and cardiac function. Under conditions of decreased blood flow, for instance through injury or atherosclerosis, blocking TSP1-CD47 interaction allows blood vessels to dilate and increases blood flow, tissue perfusion and tissue survival.

An active material useful in an oxidative dehydrogenation reactor system has an active phase, and a mixed metal oxide support phase. The active phase includes a transition metal oxide such as manganese oxide, which is reversibly oxidizable and/or reducible between oxidized and reduced states. The support phase includes a mixed metal oxide of a two or more IUPAC Group 2-14 elements. The active phase can also include a promoter such as Na-WO4 and/or a selectivity modifier such as Al or ceria. Also, a reactor including the active material in a reactor, a method of making the active material, and a method of using the active material in a regenerative reaction process.

Disclosed is a method for preparing a material of plant origin rich in phenolic acids, including at least one metal, including: preparing a material of plant origin chosen from: aquatic plants; materials rich in tannins; materials rich in lignin; and obtaining a material of plant origin, rich in phenolic acids, in which the ratio of the intensity of the vibration band of the C═O bond of the COOH group and the intensity of each of the vibration bands the aromatic ring determined in FT-IR is between 0.5 and 4. The material of plant origin is brought into contact with an effluent including from 0.1 to 1000 mg/l of at least one metal, thus obtaining a material of plant origin rich in phenolic acids including from 1 to 30% by weight of at least one metal relative to the total weight of the material.

The present invention relates to a copper aluminium oxide catalyst for preparing a furfuryl alcohol from a furfural, comprising a copper-alumina spinel structure and having surface area in the range from 0.5 to 5 m.sup.2/g; wherein said catalyst is prepared from a process comprising the following steps: (i) dissolving copper salt and aluminium salt in a solvent; (ii) adding organic acid into mixture obtained from step (i); (iii) heating mixture obtained from step (ii) at the temperature higher than 150° C. until said mixture is combusted into solid; and (iv) calcining the solid obtained from step (iii) at the temperature in the range from 700 to 1,000° C. The catalyst according to the invention gives a high conversion of furfural to furfuryl alcohol and high furfuryl alcohol yield.
