Microwave Ultrafast Heating on Iron‐based Nanogap Catalysts for CO2 Reduction Coupling with Coke Removal

open access: yesAdvanced Science, EarlyView.
This study employs a nanogap‐induced microwave discharge strategy to pretreat coke deposits on iron‐based catalysts with engineered nanogaps, causing ultrarapid heating to 1990 K within seconds, selectively eliminating >70% surface carbon deposits and converting waste plastics and greenhouse gases into syngas.

Extraction and identification of the main compound present in Elaeis guineensis flower volatiles [PDF]

open access: yes, 1985
The main compound contained in the volatile oils of the oil palm flowers was identified as l-methoxy-4 (2-propenyl) benzene or estragole. The same compound was extracted from the anthesizing male and female flowers of the oil palm (Elaeis guineensis ...

Ambient Stable Triboelectric Nanogenerator Based on Conductive Filler Modified Silicone Rubber with Gas Barrier Encapsulation for Footstep Energy Conversion

open access: yesAdvanced Science, EarlyView.
A humidity‐tolerant triboelectric nanogenerator is developed using conductive carbon black‐modified silicone rubber and a flame‐retardant gas barrier layer. The device efficiently harvests footstep energy while maintaining stable output under 30–90% RH and over 1 million cycles.

Creating Cell‐Based Hybrid Noodles for Sustainable and Nutrient‐Balanced Diets via a Serum‐Free and Animal‐Free 3D Co‐Differentiation System

open access: yesAdvanced Science, EarlyView.
This study develops a 3D co‐culture and co‐differentiation system for porcine muscle stem cells (pMuSCs) and mesenchymal stem cells (pMSCs) on edible starch‐based scaffolds. The system simultaneously generates myotubes and adipocytes without using serum or chemical inducers.

USO DE ÓLEO VOLÁTIL DE Piper amalago L. NA ATRAÇÃO DE MORCEGOS FRUGÍVOROS

open access: yesCiência Florestal, 2016
The use of volatile oils extracted from chiropterochoric fruits has been investigated so that the great number of seeds spread by fruit-eating bats in degraded areas may be potentialized.

Evaporation‐Driven Solutal Marangoni Control of Rayleigh–Taylor Instability in Inverted Films

open access: yesAdvanced Science, EarlyView.
ABSTRACT Inverted liquid films are inherently unstable: gravity amplifies perturbations through the Rayleigh–Taylor instability (RTI), causing rupture and dripping. We show that selective evaporation in volatile binary mixtures can suppress, delay, or transform this instability by inducing solutal Marangoni stresses.

Monolithic 3D Printing of Origami‐Inspired Soft Robotics from Sustainable Bio‐Based Resin

open access: yesAdvanced Science, EarlyView.
This work develops a photocurable, bio‐based resin from soybean oil for the monolithic fabrication of sustainable soft robots via Digital Light Processing. An origami‐inspired, vacuum‐actuated soft gripper is designed and fabricated, enabling reliable operation despite the material's lower elongation.
