Self‐Assembled Physical Unclonable Function Labels Based on Plasmonic Coupling

open access: yesAdvanced Optical Materials, EarlyView.
This article introduces advanced anti‐counterfeit labels crafted through DNA‐guided self‐assembly of plasmonic nanoparticles. Utilizing nanosphere lithography for dense and precise nanoparticle placement, these labels feature unique, unclonable optical signatures achieved through plasmonic coupling, detectable by an economical 3D‐printed dark field ...

Carbonized Polymer Dots‐Based Spectrally Adaptable Photonic Microbarcodes

open access: yesAdvanced Optical Materials, EarlyView.
This study explores spectrally tunable photonics barcodes using carbonized polymer dots (CPDs) based on whispering gallery mode (WGM) photoluminescence. CPDs offer wavelength‐dependent emission from visible to near‐infrared (NIR), thereby enabling variable WGM emissions.

Effective and Practical Stereoselective Synthesis of Nutlins Precursors by Immobilization of Privileged Chiral Mono‐Amidine Catalyst

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract A strategy for the immobilization of Johnston's Mono(AMidine) catalyst (MAM) onto polystyrene, silica and hybrid silica‐polystyrene nanoparticles is presented. The catalyst activity was evaluated in the stereoselective aza‐Henry reaction leading to the pivotal β‐amino nitroalkane precursors of the anti‐cancer agents Nutlins (with Nutlin‐3a as ...

Market, power, gift, and concession economies: Comparison using four-mode primitive network models [PDF]

open access: yesarXiv
Reducing wealth inequality is a global challenge, and the problems of capitalism stem from the enclosure of the commons and the breakdown of the community. According to previous studies by Polanyi, Karatani, and Graeber, economic modes can be divided into capitalist market economy (enclosure and exchange), power economy (de-enclosure and redistribution)
