A printable recording media containing a substrate; a pre-coat layer including more than about 60 wt % of one or more inorganic pigments by total dry weight of the pre-coat layer; a topcoating layer including more than about 60 wt % of one or more inorganic pigments; up to 25 wt % of binders and up to about 5 wt % of a combination of natural and synthetic rheology modifiers, by total weight of the top-coating layer, wherein the ratio of the amount of natural rheology modifiers to the amount of synthetic rheology modifiers is from about 90:10 to about 50:50. Also disclosed herein is a method for making such printable recording media.
Abstract:
An inkjet recording medium includes a substrate, an intermediate layer disposed on the substrate, and an ink receiving layer disposed on the intermediate layer. The intermediate layer includes a binder, an inorganic pigment, and a pigment ink fixing agent chosen from divalent salts, multivalent salts, and combinations thereof. The ink receiving layer includes a non-film forming polymer, a binder chosen from any of water dispersible binders or water soluble binders, and a pigment.
Abstract:
The invention provides a process for the production of a cementious material. The process comprises mixing cement starting materials and a particulate healing agent to provide the cementious material. The healing agent comprises coated particles, wherein the coated particles comprise bacterial material and additive. The bacterial material is selected from the group consisting of a bacterium, a lyophilized bacterium and a bacterial spore of a bacterium. The present invention solves these problems, as (substantially leakage-proof) tablets containing the actual healing agent may neither interfere with either the workability of the liquid mixture ("cementious material") nor negatively affect properties of either mixture or final material (hardened concrete), even when applied in large quantities. During crack formation in cementious based constructions, the particles also crack, and healing agent is released.

Abstract:
The invention relates to a vibro-acoustically effective granular aggregate for materials, e.g. concrete and similar building materials, comprising an external shell (3) with a filler made of a phase transition material (5) that can be switched using internally or externally effective fields, e.g. mechanical stress states, acoustic, electric, or magnetic fields, and at least one compact material which is embedded therein and can vibrate in said filler according to the physical condition of the phase transition material (5), whereby the mechanical state of the surrounding material is characterized and the vibro-acoustic behavior of the surrounding material is influenced.
Abstract:
A method of preparing a light weight concrete composition using expanded polymer particles that includes a) replacing from about 10 to about 50 volume percent of the coarse aggregate in the concrete composition with prepuff particles; and b) preparing the concrete composition by combining ingredients comprising 3 - 40 volume percent cement, 1 - 50 volume percent fine aggregate, 0 - 40 volume percent coarse aggregate, 10 - 22 volume percent water, and 5 - 40 volume percent of prepuff particles. The prepuff particles have an average particle diameter of from 0.2 mm to 5 mm, a density of from 0.02 g/cc to 0.56 g/cc, an aspect ratio of from 1 to 3. The concrete composition has a density of from about 90 to about 135 lb./ft3 and after it is set for 28 days, has a compressive strength of at least 1800 psi as tested according to ASTM C39.

Abstract:
The present invention relates to chemically bonded ceramic precursor material of aluminates and silicates exhibiting a controlled release rate and properties that make the material suitable as a carrier material used in drug delivery. According to the invention, this is accomplished by selecting a micro structure based on pre- reacted phases and/or reacting phases, which contains the drugs. The present invention also relates to a cured ceramic material and a method of manufacturing said cured material. The precursor and the cured ceramic material according to the present invention can suitably be used for different types of drug intake and delivery.
