Optimal shade distribution technique to mitigate partial shading effects in photovoltaic systems

open access: yes, 2018
Partial Shading (PS) critically reduces the maximum power extractable from a photovoltaic (PV) array, decreasing its efficiency, and creating multiple local peaks (LP) in the characteristic P-V curve of the array. Currently, the electrical connection that minimizes the power loss is the Total Cross Tied (TCT) connection, where each panel in a string is

Chemoselective Sequential Polymerization: An Approach Toward Mixed Plastic Waste Recycling

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by biological protein metabolism, this study demonstrates the closed‐loop recycling of mixed synthetic polymers via ring‐closing depolymerization followed by a chemoselective sequential polymerizations process. The approach recovers pure polymers from mixed feedstocks, even in multilayer formats, highlighting a promising strategy to overcome a

Bio‐Orthogonally Crosslinked Supramolecular Polymer Bottlebrush Hydrogels for Long‐Term 3D Cell Culture

open access: yesAdvanced Functional Materials, EarlyView.
Fibrous benzenetrispeptide (BTP) hydrogels, fabricated via strain‐promoted azide‐alkyne cycloaddition (SPAAC) crosslinking, form robust, bioinert networks. These hydrogels can support 3D cell culture, where cell viability and colony growth depend on the fiber content.
