Human Gut Bacteria and Lipidic Nanoparticles: Particle Composition Predicts Structural Transformation and Bacterial Biocompatibility

Advanced Functional Materials, EarlyView.
Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

Finite element simulation of ironing process under warm conditions

Journal of Materials Research and Technology, 2014
Metal forming is one of the most important steps in manufacturing of a large variety of products. Ironing in deep drawing is done by adjusting the clearance between the punch and the die and allow the material flow over the punch.

Local Scale Thermal Environment and Limited Gene Flow Indicates Vulnerability of Warm Edge Populations in a Habitat Forming Macroalga

Frontiers in Marine Science, 2020
Species inhabiting warm-edge populations of their distribution are suggested to be at the forefront of global warming due to reduced fitness, limited gene flow and living close to their physiological thermal limits.

Pickering‐Engineered Microparticles for Magnetically Guided Motion and Light‐Triggered Catalysis

Advanced Functional Materials, EarlyView.
Magnetically responsive wax microparticles stabilized by hematite cubes through the Pickering emulsification strategy are developed, showing controlled size, motion, and light‐activated catalytic activity. Annealing under a magnetic field enhances their mobility and steering.

Artery‐on‐Chip Demonstrates Mechanical and Functional Features of Healthy and Diseased Living Smooth Muscle Tissue

Advanced Functional Materials, EarlyView.
This article details the development of an artery‐on‐chip platform for in vitro arterial disease modeling and therapeutic discovery. It describes the fabrication of a fibrin biomaterial scaffold seeded with iPSC‐derived smooth muscle and endothelial cells, mimicking native artery properties. Two genetic disease models showcase the platform's ability to

Application of CaCO3 as Anti-Friction Lubricant Additive to Improve Robustness in Sheet Metal Forming of High-Strength Aluminum

Tribology Online
High-strength aluminum is a good candidate for use in light-weighting applications, but forming it is difficult due to its low formability. Elevated temperatures are therefore necessary to improve formability, but this reduces lubricant performance.

Spatially Decoupling Heating and Evaporation for Convection‐Enhanced 3D Solar Evaporation With Continuous Salt Harvesting

Advanced Functional Materials, EarlyView.
An architecture‐enabled bottom‐heated 3D solar convective evaporator spatially decouples photothermal heating from evaporation, triggering natural convection that intensifies sidewall vapour removal and heat transfer. The system achieves significantly enhanced evaporation rates over 2D and conventional 3D designs while confining salt precipitation to ...
