Ultra‐High‐Throughput Discovery of Multifunctional Polyphenolic Coatings on Droplet Microarrays

Advanced Materials, EarlyView.
An ultra‐high‐throughput (UHT) combinatorial strategy enables the miniaturized synthesis and screening of ≈30 000 polyamine‐polyphenolic (PaPp) coatings using droplet microarrays (DMA). This approach reveals hundreds of previously unknown fluorescent, redox‐active, and antibacterial materials, including multifunctional, cell‐compatible surfaces ...

Carotenoids of Lettuce (Lactuca sativa L.) Grown on Soil Enriched with Spent Coffee Grounds

Molecules, 2012
The impact of spent coffee grounds on carotenoid and chlorophyll content in lettuce (Lactuca sativa L. var. capitata) was evaluated. A greenhouse pot experiment was conducted with spent coffee amounts ranging from 0% to 20% (v/v).

All‐Polyimide‐Mediated Liquid Metal Assembly on Aerogels for Breathable and Robust Electronic Skins

Advanced Materials, EarlyView.
An all‐polyimide‐mediated assembly strategy resolves the fundamental conflict between physiological breathability and electromechanical robustness in wearable electronics. By integrating a polyamic acid‐encapsulated liquid metal ink onto an ultralight polyimide aerogel, imidization‐induced contraction enables low‐temperature conductive activation and ...

Spin‐On SiOx‐Assisted Inkjet Printing for Interdigitated n+ and p+ Poly‐Si/SiOx Contacts in Silicon Solar Cells With Suppressed Unintended Doping

Advanced Materials Technologies, EarlyView.
This work presents an innovative spin‐on SiOx‐assisted inkjet‐printed approach to form localized n+ and p+ poly‐Si/SiOx passivating contacts for high‐efficiency silicon solar cells within a single‐annealing step. The developed process results in a well‐defined interdigitated doping pattern, with unintended doping and cross‐doping concentrations ...
