First paper of Romain Lavoipierre 👏 (LEPMI phD student, cosupervised by Lara Perrin, Emilie Planes, Lionel Flandin): Electrodeposition is being investigated as an alternative method for developing large-area perovskite active layers for carbon-based solar cells. This study focuses on incorporating the 5-ammonium valeric acid iodide (5-AVAI) additive into the established MAPbI3 perovskite. Previous research has shown that 5-AVAI can enhance the performance and stability of similar solar cells produced via spin-coating, drop-casting, or inkjet printing. However, its impact on solar cells with electrodeposited active layers remains unexplored. This research investigated the synthesis and characterization of mixed 3D–2D perovskites in the (MAPbI3)1–x((AVA)2PbI4)x family processed by electrodeposition. By varying both the conversion times and 5-AVAI concentrations, we analyzed the structural, optical, and photovoltaic properties of these novel perovskites. An intricate interplay between the conversion parameters and the perovskite properties is evident. Notably, photovoltaic devices with a specific quantity of 5-AVAI showed a 65% enhancement in the power conversion efficiency after 150 h of post-treatment at 40 °C under vacuum. These findings open the way to the improved performance of electrodeposited MAPbI3 perovskites.

#Review Application of Functionalized Graphene Oxide Based Biosensors for Health Monitoring: Simple Graphene Derivatives to 3D Printed Platforms by Agnivo Gosai, Kamil Reza Khondakar, Xiao Ma and Md. Azahar Ali https://lnkd.in/e8978qZN MDPI Florida International University New York University Carnegie Mellon University #graphene #functionalizedgraphene #grapheneoxide #biosensor #3DPrinting #openaccess #Abstract Biosensors hold great potential for revolutionizing personalized medicine and environmental monitoring. Their construction is the key factor which depends on either manufacturing techniques or robust sensing materials to improve efficacy of the device. Functional graphene is an attractive choice for transducing material due to its various advantages in interfacing with biorecognition elements. Graphene and its derivatives such as graphene oxide (GO) are thus being used extensively for biosensors for monitoring of diseases. In addition, graphene can be patterned to a variety of structures and is incorporated into biosensor devices such as microfluidic devices and electrochemical and plasmonic sensors. Among biosensing materials, GO is gaining much attention due to its easy synthesis process and patternable features, high functionality, and high electron transfer properties with a large surface area leading to sensitive point-of-use applications. Considering demand and recent challenges, this perspective review is an attempt to describe state-of-the-art biosensors based on functional graphene. Special emphasis is given to elucidating the mechanism of sensing while discussing different applications. Further, we describe the future prospects of functional GO-based biosensors for health care and environmental monitoring with a focus on additive manufacturing such as 3D printing.

Incorporation of polymer chain entanglements within a single network can synergistically improve stiffness and toughness, yet attaining such dense entanglements through vat photopolymerization additive manufacturing [e.g., digital light processing (DLP)] remains elusive. Burdick et al. report a facile strategy that combines light and dark polymerization to allow constituent polymer chains to densely entangle as they form within printed structures. This generalizable approach reaches high monomer conversion at room temperature without the need for additional stimuli, such as light or heat after printing, and enables additive manufacturing of highly entangled hydrogels and elastomers that exhibit fourfold- to sevenfold-higher extension energies in comparison to that of traditional DLP. The researchers used this method to print high-resolution and multimaterial structures with features such as spatially programmed adhesion to wet tissues.

To test a 3D printing material she’s been working on, Lynn Stevens made this octopus with bulbous head and tentacles thinner than 1 mm. Stevens, a PhD student in Zachariah Page’s lab at the University of Texas at Austin, researches methods for printing objects useful in biotech, medicine, and manufacturing. In this case, the octopus is made of a hydrogel resin containing mostly cell media, a material that one day could support living cells in therapeutic implants. Because Stevens hardened the hydrogel using a fluorescent, light-triggered catalyst, the little guy glows under ultraviolet light. https://lnkd.in/emd4w_mr #CENChemPics submitted by Lynn Stevens
