Clay aerogels are foam-like materials with potential to combine high mechanical performance with fire retardancy. However, the compression strength of these aerogels is much lower than theoretically predicted values. High-strength aerogels with more than 95% porosity were prepared from a ternary material system based on poly(vinyl alcohol), montmorillonite clay platelets, and cellulose nanofibrils. A hydrocolloidal suspension of the three components was subjected to freeze-drying so that a low-density aerogel foam was formed...

BACKGROUND: Surgical wounds (incisions) heal by primary intention when the wound edges are brought together and secured, often with sutures, staples, or clips. Wound dressings applied after wound closure may provide physical support, protection and absorb exudate. There are many different types of wound dressings available and wounds can also be left uncovered (exposed). Surgical site infection (SSI) is a common complication of wounds and this may be associated with using (or not using) dressings, or different types of dressing...

Most stoma flanges are made of hydrocolloid material. Hydrocolloid is a hydrophilic material that attracts water, potentially resulting in moisture becoming trapped between the flange and skin. Also, as hydrocolloids are absorbent, the material breaks down over time, and there is a risk that some of the adhesive can remain on the skin on removal. Unlike hydrocolloids, silicone comprises fully cross-linked silicone polymers whose properties have been engineered to manage moisture without breaking down (i.e. manage the transepidermal water loss (TEWL))...
