Ultraviolet renormalon reexamined [PDF]
Physical Review D, 1996 We consider large-order perturbative expansions in QED and QCD. The coefficients of the expansions are known to be dominated by the so called ultraviolet (UV) renormalons which arise from inserting a chain of vacuum-polarization graphs into photonic (gluonic) lines.

Performance Enhancement of Silver Nanowire-Based Transparent Electrodes by Ultraviolet Irradiation
Nanomaterials, 2022 Silver nanowires (AgNWs) are used as transparent electrodes (TE) in many devices. However, the contact mode between the nanowires is the biggest reason why the sheet resistance of silver nanowires is limited.
