Argon Cold Plasma Modification of Polyethylene Films to Tailor Surface and Barrier Properties
Journal of Applied Polymer Science, Volume 143, Issue 16, April 20, 2026.Argon cold plasma treatment of low‐density polyethylene (LDPE) and high‐density polyethylene (HDPE) films induces major changes in surface chemistry and morphology. Contact angles decrease significantly while surface energy increases, improving wettability. FTIR confirms the formation of polar functional groups, while pronounced etching, roughness, and

Effect of axial compression ratio and beam end reinforcement ratio on the failure mode of RC frames
Reviews on Advanced Materials ScienceNumerous seismic damage investigations have demonstrated that reinforced concrete (RC) frame structures tend to exhibit a Strong-beam Weak-column failure mechanism, which contradicts the intended Strong-column Weak-beam design philosophy.

Fabrication and testing of an airborne ice particle counter [PDF]
An optical ice particle counter was proposed as a companion instrument to the GSFC laser nephelometer. By counting ice particles and total cloud particles (both ice and liquid water), these two instruments may be used to study the balance between ice and
