This book is written in honor of Prof. Francisco Rodriguez-Reinoso, who has made significant contributions in the area of porous materials such as active carbons and graphenes. It details the preparation of porous materials, including carbonaceous, zeolitic, and siliceous materials, MOFs, aerogels, and xerogels, describing the characterization techniques and the interpretation of the results, and highlighting common errors that can occur during the process. This book subsequently presents the use of modeling based on thermodynamics to describe the materials. Lastly, it illustrates a number of current environmental protection applications in the context of both water and air.

A filtering respiratory protective device combined with a hood for self rescue in the event of a fire or a chemical emission accident. The hood is based on a Sundström silicone half mask, which is mounted in a hood made of flame-resistant material. The hood can be put on quickly and simply without prior adjustment ( Made in USA)

The escape hood is based on the Sundström SR 100 half hood mounted in a flame-retardant and chemicals resistant material. The hood can be put on quickly and simply, without prior adjustment.The hood is vacuum-packed in an aluminum bag.

The SR 77-3 Escape Hood is a filtering respiratory protective device combined with a hood for self rescue in the event of a fire or a chemical emission accident. The hood is based on a Sundström silicone half mask, which is mounted in a hood made of flame-resistant material. The hoods are vacuum-packed in aluminum bags. The hood can be put on quickly and simply without prior adjustment.The hood is equipped with gas filter SR 331-2, ABEK1-CO and particle filter SR 510, P3 , and provides shorttime protection against carbon monoxide and other toxic gases and particles that may be emitted in a fire or in a chemical emission accident. A1, organic gases and vapours, such as solvents, with boiling points above 65 °C. B1, inorganic gases and vapours, such as chlorine, hydrogen sulphide and hydrogen cyanide. E1, acidic gases and vapours such as sulphur dioxide and hydrogen fluoride. K1, ammonia and certain amines, such as ethylene diamine.

Type E1 provides protection against acid gases and vapours, such as sulphur dioxide and hydrogen fluoride. Type K1 provides protection against ammonia and certain amines, such as ethylene diamine. Type Hg provides protection against mercury vapour. Type P3 provides protection against all types of particles, both solid and liquid. Type CO provides protection against carbon monoxide.

Disposable Blue Mask Surgical mask pack of 100 pieces Disposable Masks 3 ply layeonic Use and Throw Masks Pack of 100 Pcs Pin Certified by CE ISO GMP Best for Men Women(100-black)A surgical mask is a disposable device that creates a physical barrier between the respiratory tract openings (nose and mouth) of the wearer and potentially pathogenic contaminants in the immediate environment
Pharmaceutical masks are barriers that inhibit the environmental particulate matter from entering the respiratory orifices and prevent droplets from the nose and mouth from exiting. .
 The most popular masks are the three-layer disposable breathable masks with or without a nose pin for added support. They offer protection from airborne bacteria, fungi, viruses, etc., and other environmental pollutants. 

The Sony Underwater Housing for RX100-Series Cameras is a protective casing featuring dual water-tight gaskets that enables you to photograph in depths down to 130 ft (40 m). The dedicated design maintains access to all camera controls, including a rotary lens-ring dial, zoom lever, push buttons for menu access, and a large lever-type shutter button. The housing also permits the use of the cameras' built-in flash, and an included detachable flash diffuser can be used to lessen vignetting and provide a more even wash of lighting. Additionally, the front of the housing has 67mm filter threads to permit the attachment of color-correction filters or other threaded lens accessories. FEATURES:Dive to 130 ft (40 m) with the RX100 series - Dive to 130 ft (40 m) and shoot in pristine Cyber-shot? RX100 series digital still camera quality. Not only that, it has you covered for snorkeling, a day at the beach, winter sports, or shooting in the snow and rain.Waterproof security - Dual gaskets offer double waterproof reliability-should something get trapped in the first gasket, the second gasket will make sure the camera stays dry. 1: Drip-proof packing 2: O-ringDesigned for perfect fit - High-end design perfectly matches the compact form of the RX100 series while allowing use of the built-in flash.Expand your options - The housing features an accessory shoe to attach an optional flash, a three-holed screw mount to fit an optional stay and grip, and a 2.64" diameter filter mount to add an optional filter or conversion lens.Operation made easy - Large shutter button and zoom levers make operation simple while providing tactile push-button feedback. Adjust camera settings with control dial - Attachment of the housing still allows smooth adjustment of exposure, aperture, shutter speed, and other key camera settings via the lens ring dial.
