Fundamental study on optical performance of low-melting-point metal mirrors for space telescopes

open access: yesResults in Optics, 2023
The installation of telescopes with larger primary mirrors in outer space is required for the study of the early universe. However, the shipping, assembling and maintenance of the primary mirror are technical challenges.

CONSTRUCTION OF A PARABOLIC SOLAR COLLECTOR AND COMPARATIVE STUDY OF THE PERFORMANCE OF ALUMINUM-COATED PELLICLE FILM AND ALUMINUM FOIL AS REFLECTING SURFACES [PDF]

open access: yesJournal of Sustainable Energy, 2020
Most of the concentrators used in solar thermal systems are made from mirrors or metals with mirror or other highly reflective surfaces. Because mirror is the best reflecting surface for solar collectors and parabolic mirrors are expensive, people in the

Surface plasmon modes and the Casimir energy [PDF]

open access: yes, 2005
We show the influence of surface plasmons on the Casimir effect between two plane parallel metallic mirrors at arbitrary distances. Using the plasma model to describe the optical response of the metal, we express the Casimir energy as a sum of ...

Control of superluminal transit through a heterogeneous medium

open access: yes, 2009
We consider pulse propagation through a two component composite medium (metal inclusions in a dielectric host) with or without cavity mirrors. We show that a very thin slab of such a medium, under conditions of localized plasmon resonance, can lead to ...

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

open access: yesMolecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.
