Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract A new compilation of the complex refractive index of liquid water is presented, spanning temperatures from 240 $240$ (near homogeneous freezing) to 300 $300$ K and wavelengths from 0.034 $0.034$ μm to 10 m. The real part of the refractive index is derived using the Kramers–Kronig relation, where the imaginary part is constrained by ...

Advanced Engineering Materials, Volume 28, Issue 5, 4 March 2026.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
