Oxidation of Native and Modified Hemoglobin and Myoglobin by Sodium Nitrate. Effect of Inositol Hexaphosphate [PDF]

, 1981
Native and modified hemoglobin, myoglobin and a and phemoglobin subunits were oxidized by sodium nitrite at pH 6. The experiments were carried out under oxy and deoxy conditions with and without inositol hexaphosphate (IHP).

Effect of particle size on the surface properties and morphology of ground flax [PDF]

, 2013
Flax fibers were ground with a ball-mill and four fractions with different size ranges were collected by sieving. These were tested for water sorption, degree of polymerization (DP), copper number, hydroxyl number and analyzed by X-ray diffraction (XRD),

Oxidized Cellulose and Thrombin

Experimental Biology and Medicine, 1944
SummaryOxidized cellulose injures thrombin due to its acidity. After neutralization with sodium bicarbonate it can be mixed with thrombin without altering activity. Highly oxidized cellulose contains products capable of destroying thrombin even in neutral solutions.

Sustainable Synthesis of Bio‐Based Magnetic and Conductive Wood for Electromagnetic Interference Shielding Applications

Advanced Engineering Materials, EarlyView.
A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation
