Water Absorbing Plantation Clay for Vertical Greenery System

Synthesis of graphene oxide / polydopamine composite for coating on clay substrate for water treatment

Water purification is a vital and essential thing for human life. The presence of pollutants in water is a major threat to the environment and human health. Various materials have been proposed and used for water treatment in recent years. Recent research has shown the potential of two-dimensional materials such as graphene oxide and its composites for water purification. The goal of this proje...

Water-absorbing balls: a "growing" problem.

Foreign body ingestion is a potentially serious clinical problem in children. We report a case of an 8-month-old infant who developed complete bowel obstruction requiring laparotomy due to ingestion of a superabsorbent polymer ball with advertised growth up to 400 times its original size. Most ingested foreign bodies that pass through the pylorus will make it safely through the gastrointestinal...

Low-temperature Phases of Interfacial Water in Clay-water Systems

New absorbing layers conditions for short water waves

We develop a new PML formulation for the linearized shallow-water equations including the Coriolis force. The construction process is based on the uncoupling of the velocity components with the depth of water. Then the damping effect is only applied to the propagative modes just as was formerly done by Nataf [1] to the linearized Euler equations to enforce the long-time stability. We assess num...

Clay settling in fresh and salt water

To gain insight into the process of sedimentation occurring when clay-laden estuaries and deltas entermarinewater, we perform laboratory experiments tomeasure the settling rate of initially unflocculated kaolin clay in fresh and salt water. In fresh water, sedimentation is a slow process with the clay particle concentration gradually decreasing nearly uniformly over hours, consistent with the t...
