Closed N=2 Strings: Picture-Changing, Hidden Symmetries and SDG Hierarchy
, 1999 We study the action of picture-changing and spectral flow operators on a ground ring of ghost number zero operators in the chiral BRST cohomology of the closed N=2 string and describe an infinite set of symmetry charges acting on physical states.

Nanoporous Microelectrodes for Neural Electrophysiology Recordings in Organotypic Culture
Advanced Materials Technologies, EarlyView.The highly porous microelectrodes have been designed and printed on culture membranes, allowing to record electrophysiological neural activity for rodent brain slices. To keep the biocompatible nanoporous structure, the microelectrodes and insulative layer are fabricated on the bottom of culture membranes with only small connector pads added on the top.

Advanced Synthesis &Catalysis, EarlyView.Chiral potassium base catalysts featuring 1,1´‐bi‐2‐naphthol‐derived chiral crown ethers as ligands promote a tandem allylic isomerization/asymmetric aldol‐Tishchenko reaction of allylic alcohols and aldehydes. This method provides enantioenriched 1,3‐diols with excellent diastereoselectivity and high enantioselectivity, thereby expanding the synthetic

Advanced Sustainable Systems, EarlyView.This study analyses the uncertainty and variability existing in the economic performance of polylactic acid (PLA) production, via integrating techno‐economic analysis with process models and Monte Carlo simulation enabled by artificial intelligence. The results show that the minimum selling price varies from $2,107 to $3076/t PLA.
