Abstract: Composition for additive manufacturing by binder jet printing, comprising a ceramic particulate material subjected to a heat treatment and a binder particulate material, wherein the heat treatment comprises heating a particulate ceramic material from 600 to 1200° C. for 1 to 20 h, to produce the ceramic particulate material subjected to a heat treatment and the binder particulate material is a water-soluble compound. Method for additive manufacturing by binder jet printing of a conformed object comprising repeating the steps of depositing a layer of composition of the invention on a printing bed and depositing a liquid binder. The invention solves the problems of mechanical fragility of objects conformed by binder jet printing and design defects thereof, wherein the heat treatment creates bonds and aggregations between particles of the ceramic material, maintaining them during printing.

Abstract: Ear muffs including a pair of arm members, each arm member provided with a noise suppression portion mounted rotatably thereto adjacent a first end of each arm member and having a first portion of an attachment system located at a second opposite end of each arm member, the first portion of the attachment system attachable to a second portion of the attachment system provided on a carrier portion adapted to be supported on a wearer's head.

Abstract: This invention is based upon the application of compatible solutes to immobilized biological materials or to immobilize in order to improve the technical performance using the same, namely nucleic acid and proteins or biosensors micronets. The above mentioned compatible solutes are selected from a group that includes Mannosylglycerate (MG) and its 3 derivatives manno-sylglyceramide (MGA), -mannosylglycerol (MGOH), and mannosyl-lactate (MGLac), 1,1-di-glycerol phosphate (DGP), ectoin, hydroxyectoin, and or derivatives or combinations thereof. The improved performance of the above mentioned techniques might be due to: a better state of preservation of the material to be immobilized, increasing the life expectancy of the material, and/or decreasing the storage and/or transport requirements, a more efficient and uniform deposition of the material on the support, more efficiency and/or specificity of hybridation of the marked material, all this originating an increase of the signal-to-noise ratio.
