  • Patent number: 11964058
    Abstract: A process can be used for preparing nanoparticles containing at least one bio-resorbable polyester. The nanoparticles are in the form of a powder with a Z-Average particle size Dz in the range of 1 to 450 nm, and with a polydispersity index PDI in the range of 0.01 to 0.5. The process involves emulsion-solvent extraction or emulsion-solvent evaporation, and application of ultrasonic sound.

  • Publication number: 20230241816
    Abstract: Prepared is a laminate including: a first layer formed of a first resin composition containing a first resin; and a second layer formed of a second resin composition containing a second resin, the first layer and the second layer being in contact with each other and integrated. The first resin includes an alicyclic polyamide resin having 20 mmol/kg or greater of amino groups, and the second resin includes an acid-modified (meth)acrylic resin. The second resin may have 100 mmol/kg or greater of carboxyl groups. The acid-modified (meth)acrylic resin may be an acid-modified polymethylmethacrylate resin. An average thickness of the first layer may be 0.15 times or more of an average thickness of the second layer. The average thickness of the first layer may be 200 ?m or greater. When a weight is dropped onto the second layer side, the laminate may have a DuPont impact strength of 500 N/inch or greater. The laminate has excellent transparency, lightness, light resistance, and impact resistance.

  • Publication number: 20220134274
    Abstract: A device for separating a gas stream which has a compressor and three membrane separation units in series, connected to pass the retentate stream of each of the first two units to the subsequent membrane separation unit, comprises conduits for recycling the permeate streams of the second and the third membrane separation unit to upstream of the compressor and a control device controlling the fraction of the second permeate stream which is recycled. Adjusting which fraction of the second permeate is recycled can be used to maintain a target composition of the retentate obtained in the third membrane separation unit when the flow rate or the composition of the gas stream changes.
