Forensic scientists use different techniques for porous surfaces, such as paper, and nonporous surfaces, such as glass, metal or plastic. Nonporous surfaces require the dusting process, where fine powder and a brush are used, followed by the application of transparent tape to lift the latent fingerprint off the surface. While the police often describe all partial fingerprints found at a crime scene as latent prints, forensic scientists call partial fingerprints that are readily visible patent prints. Chocolate, toner, paint or ink on fingers will result in patent fingerprints.

Movement is transmitted from traditional nonporous spherical implants through the surface tension at the conjunctival–prosthetic interface and movement of the fornices. Quasi-integrated implants have irregularly shaped surfaces that create an indirect coupling mechanism between the implant and prosthesis that imparts greater movement to the prosthesis. Directly integrating the implant to the prosthesis through an externalized coupling mechanism would be expected to improve motility further. Despite the reasoning stating that hydroxyapatite orbital implants without a motility peg would yield a superior artificial eye motility, when similar surgical techniques are used unpegged porous (hydroxyapatite) enucleation implants and donor sclera- covered nonporous (acrylic) spherical enucleation implants yield comparable artificial eye motility.

There are many different types of implants, classification ranging from shape (spherical vs egg (oval) shaped), stock vs custom, porous vs nonporous, specific chemical make-up, and the presence of a peg or motility post. The most basic simplification can be to divide implant types into two main groups: non-integrated (non-porous) and integrated (porous).

Acetone-Rosin Treatment is used on dense wood that cannot be penetrated by PEG. This would include softwoods that are nonporous. The goal of this treatment is to replace cells of wood with natural rosin. Rosin is a natural resin that is produced within some woods, for example pines naturally produce resin and are considered a softwood.

Ceramic fixtures are being more commonly glazed with 2 part epoxy compounds. The first component is a clear or opaque resin combined with a catalyst or hardener. The proper procedure requires that the nonporous fixture be sand blasted to create a rough surface for the epoxy primer to adhere to. Once the primer has dried the topcoat is applied.

Colloidal silicas are suspensions of fine amorphous, nonporous, and typically spherical silica particles in a liquid phase. Schematic representation of the silica gel surface. The surface of colloidal silica in contact with water is covered by siloxane bonds (≡Si–O–Si≡) and silanol groups (≡Si–OH). This makes colloidal silica very hydrophilic and capable of forming numerous hydrogen bonds.

Tree box filters are designed to accommodate a low volume of rainfall. A filter surface area of forty-eight feet can only cover up to a quarter of an acre of impervious or nonporous surface. As a result, strategically positioning multiple tree boxes around the area of coverage is vital, when trying to reduce costs and work.

Reverse osmosis instead involves solvent diffusion across a membrane that is either nonporous or uses nanofiltration with pores 0.001 micrometers in size. The predominant removal mechanism is from differences in solubility or diffusivity, and the process is dependent on pressure, solute concentration, and other conditions.Crittenden, John; Trussell, Rhodes; Hand, David; Howe, Kerry and Tchobanoglous, George (2005). Water Treatment Principles and Design, 2nd ed.

Synthetic pyrethroids are the main class of insecticides used to control triatominae infestations. Insecticide treatment is more effective on nonporous surfaces, such as hardwood timber, fired bricks, and plastered walls, than on porous surfaces such as mud. A single treatment with insecticide typically protects against triatomine infestation for a year or more on timber walls vs. 2–3 months on adobe walls.

8, pp. 953-983. He described it as “gray to brown, dense, cryptocrystalline limestone.” This description incorrectly implied a nonporous, non-permeable unit that lacks any potential for oil and gas production, which has discouraged until recently the exploration for oil and gas in this unit.Heydari, E. (2010) Hydrocarbon potential of the lower Smackover Formation in the north-central Gulf of Mexico (Arkansas, Louisiana, and Mississippi).

Many plastics, such as polyethylene and polypropylene, have chemically inert and nonporous surfaces with low surface tensions causing them to be non-receptive to bonding with printing inks, coatings, and adhesives. Although results are invisible to the naked eye, surface treating modifies surfaces to improve adhesion. Polyethylene, polypropylene, nylon, vinyl, PVC, PET, metalized surfaces, foils, paper, and paperboard stocks are commonly treated by this method. It is safe, economical, and delivers high line speed throughput.

Using a nonporous ceramic mortar and pestle, a small quantity of the solid sample is ground up until the sample is exceedingly fine and has a glassy appearance. A drop of the mulling agent is added to the ground solid in the mortar. The mixture is further ground up until a uniform paste with the consistency of toothpaste is acquired. The resulting paste is transferred to a salt plate (NaCl) with a small flat spatula.

This mildly photosensitive solution is then applied to a receptive surface (such as paper or cloth) and allowed to dry in a dark place. Cyanotypes can be printed on any surface capable of soaking up the iron solution. Although watercolor paper is a preferred medium, cotton, wool and even gelatin sizing on nonporous surfaces have been used. Care should be taken to avoid alkaline-buffered papers, which degrade the image over time.

Universal precautions refer to the practice, in medicine, of avoiding contact with patients' bodily fluids, by means of the wearing of nonporous articles such as medical gloves, goggles, and face shields. The practice was widely introduced in 1985–88. In 1987, the practice of universal precautions was adjusted by a set of rules known as body substance isolation. In 1996, both practices were replaced by the latest approach known as standard precautions.

A wax pencil resembles both a crayon and a pencil in that it contains a brightly colored wax core within a protective paper casing, but its proportions are closer to that of a standard pencil. Wax pencils are primarily used to write onto nonporous surfaces such as porcelain or glass. Normal pencils, chalk, and crayons all share the characteristic that they cannot "run out". The useful life of these implements is closely linked to their physical existence.

Contaminants applicable to the use of an SPMD include, but are not limited to, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides, dioxins, and furans. The SPMD consist of a thin- walled, nonporous, polyethylene membrane tube that is filled with high molecular weight lipid. These tubes are approximately 90 cm long and wrap around the inside of a stainless steel deployment canister. SMPDs are efficient at absorbing pollutants with a log Kow of 4-8.

The United States Naval Research Laboratory developed nanoporous membrane microbial fuel cells that use a non-PEM to generate passive diffusion within the cell. The membrane is a nonporous polymer filter (nylon, cellulose, or polycarbonate). It offers comparable power densities to Nafion (a well known PEM) with greater durability. Porous membranes allow passive diffusion thereby reducing the necessary power supplied to the MFC in order to keep the PEM active and increasing the total energy output.

These objects have a special varnish that make them useful for cooking, the varnish acting like a coating of Teflon that prevents food from slicking when heated. High fire wares like alta clay and stoneware were introduced to the area by American Ken Edwards and Mexican Jorge Wilmot starting in the 1960s. These are fired at over 1,100C, causing the clay to vitrify and form a nonporous surface. The first stoneware kiln was installed in Tonala and spread from there.

The simple device can be created in the laboratory using a nonporous polymeric tube, such as low-density polyethylene (LDPE) plastic. A sequestration medium within the tube slowly defuses through the membrane, binding to ionic metals creating non-mobile metals species that can later be extracted from the other membrane. The sequestration medium generally consists of a metal binding agent, or chelating agent, and a long chain organic acid, commonly oleic acid. The SLMD tube is flat with a membrane thickness that can vary between 2 and 500 μm depending on the application.

A US Navy hospital corpsman wearing personal protective equipment (PPE) while handling blood samples. Universal precautions refers to the practice, in medicine, of avoiding contact with patients' bodily fluids, by means of the wearing of nonporous articles such as medical gloves, goggles, and face shields. The infection control techniques were essentially good hygiene habits, such as hand washing and the use of gloves and other barriers, the correct handling of hypodermic needles, scalpels, and aseptic techniques. Following the AIDS outbreak in the 1980s the US CDC formally introduced them in 1985–88.

These are fired at over 1,100 °C, causing the clay to vitrify and form a nonporous surface. The main difference between the Wilmot and Edwards styles is that Wilmot maintained the area's traditional decorative styles, focusing on images of suns, birds, eagles, lions and flowers. He also founded a new school of ceramic production which remains to this day, using a traditional green-gray background with images made of small dots, often of double headed eagles, lions and multicolored suns. Edwards' ceramics have a blue-gray backgrounda and delicate decorations with Oriental influence.

Active guiding systems are composed of a sensor, an actuator connected to a guide mechanism, and a controller. The sensor can be any detector, which can reliably pick up the edges of a web. The most common types of sensors are pneumatic (only works with nonporous webs), optical (works well with opaque webs), ultrasonic (works with most material), or paddies (thick webs). Recent developments have introduced to the industry a new sensor technology based on light scattering and spatial filtering that allows the use of an optical sensor to detect the edge of any material.

And although the porous implants have been reported to offer improved implant movement, these clearly are more expensive and intrusive, requiring wrapping, and subsequent imaging to determine vascularization and pegging to provide for better transmission of implant movement to the prosthesis, and also are prone to implant exposure. Age and size of the implant may also affect the motility, since in a study comparing patients with hydroxyapatite implants and patients with nonporous implants, the implant movement appeared to decrease with age in both groups. This study also demonstrated improved movement of larger implants irrespective of material.

An artist's palette A palette , in the original sense of the word, is a rigid, flat surface on which a painter arranges and mixes paints. A palette is usually made of wood, plastic, ceramic, or other hard, inert, nonporous material, and can vary greatly in size and shape. The most commonly known type of painter's palette is made of a thin wood board designed to be held in the artist's hand and rest on the artist's arm. Watercolor palettes are generally made of plastic or porcelain with rectangular or wheel format with built in wells and mixing areas for colors.

The porous nature of integrated implants allows fibrovascular ingrowth throughout the implant and thus also insertion of pegs or posts. Because direct mechanical coupling is thought to improve artificial eye motility, attempts have been made to develop so-called 'integrated implants' that are directly connected to the artificial eye. Historically, implants that directly attached to the prosthesis were unsuccessful because of chronic inflammation or infection arising from the exposed nonporous implant material. This led to the development of quasi- integrated implants with a specially designed anterior surface that allegedly better transferred implant motility to the artificial eye through the closed conjunctiva and Tenon's capsule.

MOXIE collects from the Martian atmosphere, then electrochemically splits the molecules into and CO. A solid oxide electrolysis cell works on the principle that, at elevated temperatures, certain ceramic oxides, such as yttria-stabilized zirconia (YSZ) and doped ceria, become oxide ion (O2–) conductors. A thin nonporous disk of YSZ (solid electrolyte) is sandwiched between two porous electrodes. For oxygen generation from carbon dioxide, CO2 diffuses through the porous electrode (cathode) and reaches the vicinity of the electrode-electrolyte boundary. Through a combination of thermal dissociation and electrocatalysis, an oxygen atom is liberated from the molecule and picks up two electrons from the cathode to become an oxide ion (O2–).

The stabilized liquid membrane device (SLMD) is a passive, integrative sampler that provides an alternative or complementary approach to the conventional water sampling of aqueous metals. The simple device is composed of nonporous low-density plastic lay-flat tubing, which is filled with a chemical mixture containing a chelating agent (metal-binding agent) and a long chain organic acid. The water-insoluble chelating agent-organic acid mixture diffuses in a controlled manner to the exterior surface of the sampler membrane and binds to environmental metals. In practice, the SLMD provides for continuous sequestration of bioavailable forms of trace metals, such as, cadmium (Cd), cobalt (Co), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn).
