Development and testing of dry chemicals in advanced extinguishing systems for jet engine nacelle fires [PDF]
The effectiveness of dry chemical in extinguishing and delaying reignition of fires resulting from hydrocarbon fuel leaking onto heated surfaces such as can occur in jet engine nacelles is studied. The commercial fire extinguishant dry chemical tried are

Advanced Science, EarlyView.Lipid metabolic stress triggers ferroptosis in PDLSCs through the GSK3β/NRF2 pathway, thereby aggravating periodontal bone loss. Upregulated GSK3β promotes NRF2 ubiquitination and proteasomal degradation via β‐TrCP, suppressing NRF2 nuclear translocation and antioxidant target expression.

Iterative Synthesis of Pentacene Derivatives with Continuous Boron–Oxygen Bonds
Angewandte Chemie, EarlyView.An iterative synthetic strategy enables the controlled introduction of continuous multiple B–O bonds at the zigzag edge of acenes. A simple two‐step cycle—ipso iodination and Suzuki cross‐coupling/condensation—efficiently constructs BO‐acenes ranging from naphthalene to pentacene.

Iodine value in pregravidal period of a woman’s life [PDF]
Гинекология, 2014 Iodine is an essential trace element, which is essential for the formation and development of a complete organism. Attempts to eliminate iodine deficiency are reduced to mass prevention by iodination of certain foods, but it is not possible to prevent ...

Electronic structure and charge distribution of potassium iodide intercalated single-walled carbon nanotubes [PDF]
, 2004 Recently, potassium iodide was inserted into single-walled carbon nanotubes. We present here a first-principles density-functional theory calculation of the electronic and optical properties of a potassium iodide intercalated (10,10) nanotube.
