Phosphorus

Yellow phosphorus (white phosphorus) is a significantly more hazardous form of the element and may be present as a contaminant in red phosphorus This allotrope of phosphorus is extremely toxic and the estimated human lethal dose is 50 - 100 mg This form must be stored under water as it burns rapidly and is spontaneously combustible upon exposure to air

Unravelling the Photoprotection Properties of

Photoprotection from harmful ultraviolet (UV) radiation exposure is a key problem in modern society Mycosporine-like amino acids found in fungi cyanobacteria macroalgae phytoplankton and animals are already presenting a promising form of natural photoprotection in sunscreen formulations Using time-resolved transient electronic absorption spectroscopy and guided by complementary ab initio

Phytofuse Rejuvenate

Phytofuse Rejuvenate is a natural alternative for the current carbohydrate chemistry seen in the medical industry for the creation of synthetic scaffolding that promotes wound healing The isolated polysaccharides extracted from the Salvia hispanica seed have demonstrated their ability to aid in cell proliferation and thus impart wound healing and anti-inflammatory properties to the skin

Innate immune receptor NOD2 mediates LGR5

The intestinal epithelium represents the most vigorously renewing adult tissue in mammals The renewal process is supported by the presence of intestinal stem cells (ISCs) Here we decipher a pathway of ISC cytoprotection mediated by a microbiota-derived product the muramyl dipeptide (MDP) During stress conditions recognition of MDP by the cytosolic sensor NOD2 which is expressed at high

Regarding the radiation protection I believe that it depends on how the the dark layer absorbs light in all spectral range of the sun light i e absorption coefficient and thickness of the material+dye It also depends on how the reflective layer reflects the light i e reflectance I believe that the radiation protection does not depend on the arrangement so both schemes protect from

Silicon Microspheres as UV Visible and Infrared Filters

Silicon microspheres are described as UV visible and infrared (IR) radiation filters Parameters of these spheres including shape smoothness refractive index and size are examined for their potential benefits in cosmetic formulations Finally the ability of the spheres to block IR radiation is evaluated for thermo-regulatory effects

Pitting Corrosion

Pitting corrosion is a localized form of corrosion by which cavities or holes are produced in the material Pitting is considered to be more dangerous than uniform corrosion damage because it is more difficult to detect predict and design against Corrosion products often cover the pits A small narrow pit with minimal overall metal loss can lead to the failure of an entire engineering
