Hybrid Two‐Step Inkjet Printing and Dip‐Coating Enable Scalable 30%‐Efficient Perovskite/Silicon Tandem Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Adopting a scalable hybrid two‐step deposition process route, textured perovskite/silicon tandem solar cells achieve over 30% power‐conversion efficiency. The process route replaces all non‐scalable spin‐coating steps, including organic precursor deposition, self‐assembled monolayer formation, and passivation layer deposition, with scalable techniques ...

How Video‐Based Information Affects Farmers' Willingness to Pay for Drone Services

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Professional service for digital technology like agricultural drones lowers transaction costs and scope thresholds for smallholders. Meanwhile, perceptual adoption barriers remain underexplored. We conduct a two‐stage choice experiment with a randomized video‐based information treatment among 384 Chinese crop farmers to measure its effect on ...

Interaction Between Operator and Assistant Certification Is Associated With Local Recurrence After Laparoscopic Rectal Cancer Surgery: An Ancillary Analysis of the EnSSURE Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
A significant synergistic interaction between operator and assistant certification was associated with a lower risk of local recurrence after laparoscopic rectal cancer surgery. Patients treated by both ESSQS‐qualified operators and assistants had the lowest risk of local recurrence, whereas a single qualification alone was not associated with a ...

Current Standards of Monitoring Models in Healthcare Settings

open access: yesAdvanced Intelligent Discovery, EarlyView.
AI/ML‐enabled medical devices are entering clinical practice faster than monitoring standards mature. This review highlights gaps in postmarket surveillance, limited use of predetermined change‐control plans, and the need for ongoing performance tracking, drift detection, explainability, and workflow‐aware governance to support safer, more reliable ...

Extending El Sayed's Rule by 1(n,π*)–3(n,π*) Rotation via Intramolecular Secondary Interaction Enables Room‐Temperature Circularly Polarized Phosphorescence in Solution

open access: yesAngewandte Chemie, EarlyView.
Weak but skilled: Our results highlight the crucial role of intramolecular secondary interactions to induce an efficient ISC between formally identical 1(n,π*) and 3(n,π*) states in chiral thionated phthalimide derivatives. This unprecedented type of inter‐system crossing (ISC) extends the usual thinking of the El‐Sayed principle and enables the ...

Lab‐Scale Fabrication Process Selection for Soft Robotics: Benchmarking, Tradeoffs, and Guidelines for Formative Manufacturing of Soft Silicone Components

open access: yesAdvanced Intelligent Systems, EarlyView.
Fabrication shapes soft robot performance, but benchmarking data and selection guidelines remain scarce. We fabricate silicone actuators using two molding techniques and three mold types, characterizing them with cycle testing, microscopy, profilometry, and 3D imaging. Applying our lab‐scale, soft robotics‐specific fabrication evaluation criteria shows
