摘要:
While facing polluted environments one does not need extreme breath filtering protection all the time. Methods of the art hardly focus on breathability aspect while working on smart masks. Embodiments of the present disclosure provide a system and method for context aware networked mask with dynamic air impedance for optimum breathability. The system provides a smart mask that regulates the air inlet (by modulating the position / pore size of filtering membrane or by using resizable gel) as per the prevalent risk at that instance. The context aware mask with a mesh network, disclosed herein, comprises sensors and processing unit, which use contextual information and Artificial Intelligence to develop models for generating alerts along with mechanism of dynamically regulating the pore size to ensure breathability by adjusting air impedance.

Dans un procédé de séparation d'argon par distillation cryogénique dans lequel un débit (2) contenant de l'argon, de l'oxygène et de l'azote, plus riche en argon que l'air, est envoyé à une colonne de distillation (1),un débit gazeux riche en argon (3) est soutiré en tête de la colonne, une partie du débit gazeux riche en argon (11) est mélangée avec des billes ayant un diamètre inférieur à 5mm pour former un mélange gazeux (15) contenant des billes, les billes étant en matière adsorptive capable d'adsorber de l'oxygène en présence d'argon aux températures d'opération de la colonne, la partie du débit gazeux riche en argon mélangée avec les billes est condensée puis est envoyée en tête de la colonne et un liquide de cuve (19) contenant des billes est soutiré de la colonne et traité pour enlever les billes, les billes enlevées sont régénérées pour enlever l'oxygène adsorbé et sont de nouveau mélangées avec la partie du débit gazeux riche en argon.

Disclosed herein are finished products, methods, compositions and kits for derivatizing plastic (e.g., "polymer") surfaces in a manner that renders the surfaces appropriate for various downstream applications. For example, flow cells incorporating modified plastic surfaces provide greatly enhanced stability for retention of attached chemical species such as polypeptides and nucleic acids.
摘要:
The present invention relates to a method for treatment and/or purification of water, in particular wastewater or drinking water, preferably for the adsorptive removal of inorganically based or organic, in particular organically-based, impurities, such as trace substances and/or micropollutants, wherein, in a counterflow filter device, in particular a counterflow adsorption filter column, the water that is to be treated and/or that is to be purified firstly, and, secondly, an, in particular particulate, adsorption material are conducted in counterflow and/or in opposite direction to one another. In particular, in this case, a procedure is followed in such a manner that the water that is to be treated and/or that is to be purified is passed through a bed of the adsorption material present in the counterflow filter device for the adsorptive removal of impurities and the bed is exchanged and regenerated by preferably continuous removal and supply of the adsorption material in counterflow to the water that is to be treated and/or that is to be purified.
摘要:
A method of preparing a separation column, or channel in a microfabricated device, includes the steps of: providing an unfilled column, or channel in a microfabricated device; activating the inner wall of the column or channel with an activating agent; filling the column with a polymerization solution including a mixture of monomers, at least one porogen and at least one polymerization initiator; and polymerizing the mixture to form a rigid porous monolithic polymer plug in the column or channel. The monomers include a mixture of divinylbenzene as major monomer and isodecylacrylate, and the at least one porogen includes isobutanol.
