Optically responsive dry cholesteric liquid crystal marbles
Dry liquid crystal marbles are structures that consist of cholesteric liquid crystal (CLC) droplets prepared by the mixture of chiral-doped thermotropic LCs encapsulated by cellulose nanocrystals (CNCs) that have been dried under ambient conditions. The ch ...
Academic Press Inc Elsevier Science2024Layered metals as polarized transparent conductors
Philip Johannes Walter Moll, Maja Deborah Bachmann, Matthias Carsten Putzke, Chunyu Guo
The quest to improve transparent conductors balances two key goals: increasing electrical conductivity and increasing optical transparency. To improve both simultaneously is hindered by the physical limitation that good metals with high electrical conducti ...
NATURE PORTFOLIO2023Selectively permeable microcapsules
Microcapsules are appealing containers for delivering active ingredients, such as drugs and cosmetics, or conducting chemical and biological reactions on a small scale. To control the timing and location of release of these encapsulants, the shells of micr ...
EPFL2023Enhancement of Pressure-Sensitive Adhesive by CO2 Laser Treatment
Dario Floreano, Vivek Ramachandran, Yegor Piskarev, Jun Shintake, Michael Dickey, Jianhang Yang
Pressure-sensitive adhesives (PSAs) are polymeric films that can be adhered to and detached from surfaces without leaving residue. Researchers are looking to enhance the bond strength between PSAs and different substrates. It can be achieved by tuning PSA' ...
