The overall concept of NanoBarrier is to develop a new nanotechnology platform based on inorganic-organic hybrid polymers, microfibrillated cellulose, nanocapsules with controlled permeability and additive technology and combine this with resource-efficient processing technologies to realize safe and extended shelf-life and multifunctional biopolymer food packaging solutions. These solutions based on CO2 neutral and renewable resources, should work as an enabling technology for innovative companies to stimulate to further consumption growth of fish and seafood and environmental conscious packaging solutions for meat and dairy products; food sectors of major social, economical and health impact in the European region. The project will also bring forward robust biopolymer formulations, compounding expertise and coating approaches to combine nanoparticle technology with biopolymer formulations. Dedicated demonstrators are planned based on resource-efficient processing technologies, such as blow moulding and film blowing. The demonstrators will be multifunctional barrier films for meat packaging, multifunctional barrier bottles for liquid yoghurt and milk and multifunctional barrier jars for crab packaging. NanoBarrier will include sustainable parameters from the demonstrator design step applying ecodesign methodology to minimize the environmental, social and economic impact from the early development step. An LCA will quantify the impact of the foreseen demonstrators and measures are taken to evaluate safety. The objectives of the project will be achieved by implementing the work organized in four technical work packages (in addition to a coordination work package) where each WP are designed to fulfill one- or several of the specific scientific objectives in the project. The project consortium cover the whole value chain from manufacture and competence of nanoparticle technology to end-use supply and include leading organizations and competences throughout Europ


Compositions containing a biologically active material and a non-ordered inorganic oxide material are disclosed. Methods of making and using compositions containing a biologically active material and a non-ordered inorganic oxide material are also disclosed.


Patent
WR Grace and LBeste Gat Ltd. | Date: 2016-09-23

The present invention provides compositions and methods involving the use of a carboxylate graft polymer having high molecular weight and low ratio of acid-to-polyoxyalkylene groups. Such clay-mitigation is particularly useful for treating clay and clay-bearing aggregates, particularly those aggregates used for construction purposes. The present invention minimizes the need to wash the aggregates, thus preserving fine aggregates (fines) content in construction materials, and thereby beneficiating the performance and/or properties of construction materials containing the clay-bearing aggregates.

The invention provides an aqueously-swellable water stop having an elongate body formed by shaping or extruding a composition mixture comprising water swelling fillers and/or polymers (e.g. Bentonite, super absorbent polymers, hydrophilic polymers), at least one elastomer or polymer, and preferably at least one plasticizer, the composition mixture when formed into an elongate water stop body having a Shore A hardness (durometer) of less than 35 and more preferably in the range of 5-35 (measured at 21C). The water stop body has at least one major face and a layer of pressure-sensitive adhesive attached to the face for bonding to a concrete substrate. The water stop of the invention does not require use of rigid metal and hard plastic inner cores as in prior water stop designs, and avoids curling and snaking that would allow concrete poured against the water stop to invade between the first substrate and the water stop body, and thereby providing full bonding between the water stop and thus protecting against leakage through concrete construction joints.


Disclosed are thermoformed articles comprising a propylene-based polymer comprising a substituted 1,2-phenylene dibenzoate selected from the group consisting of 3-methyl-5-tert-butyl-1,2-phenylene, dibenzoate and 3,5-diisopropyl-1,2-phenylene dibenzoate. The thermoformed articles have high stiffness, good compression strength, excellent processability, and excellent optics.


The present disclosure provides a process. In an embodiment, the process includes producing a propylene-based polymer in a gas-phase polymerization reactor (10) under polymerization conditions. The polymerization conditions include a combined propylene-plus-propane partial pressure from 290 psia to 450 psia. The process further includes maintaining the combined propylene-plus-propane partial pressure in the range from 290 psia to 450 psia while simultaneously: (i) reducing propylene partial pressure in the gas-phase polymerization reactor; (ii) adding propane to the gas-phase polymerization reactor; (iii) introducing at least one C4-C10 comonomer into the gas-phase polymerization reactor (26); and forming a propylene/C4-C10 interpolymer in the gas-phase polymerization reactor (44).

Chromatography devices contain chromatography media and methods of making and methods of using chromatography devices. Chromatography devices enable a more efficient, productive and/or environmentally friendly chromatographic operation due to one or more of the following advantages over conventional chromatographic operations: elimination of a device packing step by the user; elimination of clean-in-place (CIP) steps; elimination of clean-in-place (CIP) steps utilizing sodium hydroxide solution; elimination of any validation steps by the user; and use of a chromatography device comprising biodegradable material. The chromatography media includes porous inorganic particles having a functionalized surface and having a median pore size of at least about 300 Angstroms (A), or at least about 300 A up to about 3000 A. The inorganic particles may have a BET surface area of at least about 20 m2/g, or at least about 25 m2/g, or about 30 m2/g, up to about 2000 m2/g.


Patent
WR Grace | Date: 2014-12-18

Compositions and methods of the present invention comprise the use of at least one alkoxylated fatty compound comprising at least one propylene oxide group, the alkoxylated fatty compound having a turbidity most preferably greater than 1000 NTU (as measured in a 0.2 weight percent aqueous solution) and carbon dispersing compound (e.g., lignosulfonate) to reduce carbon spotting in mortars and concretes containing a carbon-bearing fly ash having a methylene blue (MB) value of at least 1 mg/g or greater (as 10 determined according to ASTM C1777-13). The compositions may, for example, be combined as dry powder with the carbon-bearing fly ash where the fly ash is produced, or in aqueous liquid composition form, such as would be suitable for dispensing at a concrete ready-mix plant. Exemplary additive or admixture compositions may further comprise air entraining agents, alkanolamines, or both.


The process of this invention removes impurities from transesterification products comprising primarily fatty acid alkyl esters (FAAE) that are being processed for final fuel products, such as biodiesel. The inventive process is catalytic, and the resulting ester is suitable for use as biodiesel. Metal oxide and mixed metal oxide catalysts are particularly suitable. The invention is particularly suitable for treating fatty acid alkyl ester compositions comprising impurities such as glycerin, sterol glycosides, and/or triglyceride, diglyceride and/or monoglyceride. The invention is particularly useful in treating FAAE transesterification products made using homogeneous alkali catalysts. The treated ester exhibits improved performance under cold weather conditions, which can be measured by methods such as ASTM 7501 Cold Soak Filtration Test (CSFT).
