Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, is a silicone polymer with a wide variety of uses, from cosmetics to industrial lubrication and passive daytime radiative cooling. [1] [2] [3] PDMS is particularly known for its unusual rheological (or flow) properties.
PDMS is treated with oxygen plasma and placed in contact with the functionalized thermoplastic surface. A stable, covalent bond forms within 2 minutes. Silsesquioxane synthesis
n R 2 Si(OH) 2 → (R 2 SiO) n + n H 2 O. The linear products, polydimethylsiloxane (PDMS), are of great commercial value. Their production requires the production of dimethylsilicon dichloride. Starting from trisilanols, cages are possible, such as the species with the formula (RSi) n O 3n/2 with cubic (n = 8) and hexagonal prismatic (n = 12
It is called "soft" because it uses elastomeric materials, most notably PDMS. Soft lithography is generally used to construct features measured on the micrometer to nanometer scale. According to Rogers and Nuzzo (2005), development of soft lithography expanded rapidly from 1995 to 2005. Soft lithography tools are now commercially available. [2]
RIFLE - Risk, injury, failure, loss and end-stage kidney classification [2] has 3 severity levels (risk, injury and failure) and 2 possible outcomes (loss and end-stage) CP - Child–Pugh score [2] for patient with liver failure. used also outside of the ICU.

PDMS (Plant Design Management System) as it is known in the 3D CAD industry, is a customizable, multi-user and multi-discipline, engineer controlled design software package for engineering, design and construction projects in offshore and onshore.
0-2: A score of 0-2 indicates no change in a child's status and regular rounding is acceptable. The plan of care will be continued as is. [35] 3-4: Indicates that a child's care is worsening, but they do not need immediate assistance. The plan of care may change or continued close monitoring will be initiated. [35]
