Osmosis-driven stiffening of structured hydrogels
Esther Amstad, Ran Zhao, Alexandra Thoma
Plant cells harness osmotic pressures to stiffen their leaves through strong turgor pressures. Key to this osmosisdriven stiffening is the confinement of liquids within semipermeable membranes that can regulate the transport of water molecules and ions. In ...
Elsevier2024Tree diversity reduces variability in sapling survival under drought
Charlotte Grossiord, Jingjing Liang, Xiaojuan Liu
Enhancing tree diversity may be important to fostering resilience to drought-related climate extremes. So far, little attention has been given to whether tree diversity can increase the survival of trees and reduce its variability in young forest plantatio ...
Wiley2024Confinement-Controlled Crystallization of Guanine
Guanine crystals are frequently encountered in nature in the beta-polymorph to create structural colors, to enhance the vision of creatures, and for camouflage. Unfortunately, it is challenging to control the crystallization of guanine in aqueous condition ...
Amer Chemical Soc2024In situ quantification of osmotic pressure within living embryonic tissues
Sangwoo Kim, Antoine Claude Jean Vian
Mechanics is known to play a fundamental role in many cellular and developmental processes. Beyond active forces and material properties, osmotic pressure is believed to control essential cell and tissue characteristics. However, it remains very challengin ...
2023Selectively permeable microcapsules
Microcapsules are appealing containers for delivering active ingredients, such as drugs and cosmetics, or conducting chemical and biological reactions on a small scale. To control the timing and location of release of these encapsulants, the shells of micr ...
EPFL2023Interactions between beech and oak seedlings can modify the effects of hotter droughts and the onset of hydraulic failure
Charlotte Grossiord, Eugénie Isabelle Mas, Hervé Cochard, Margaux Clara Lou Didion-Gency, Janisse Deluigi, Fernando Valladares
center dot Mixing species with contrasting resource use strategies could reduce forest vulnerability to extreme events. Yet, how species diversity affects seedling hydraulic responses to heat and drought, including mortality risk, is largely unknown. Using ...
Hoboken2023Stability of tropical forest tree carbon-water relations in a rainfall exclusion treatment through shifts in effective water uptake depth
Increasing severity and frequency of drought is predicted for large portions of the terrestrial biosphere, with major impacts already documented in wet tropical forests. Using a 4-year rainfall exclusion experiment in the Daintree Rainforest in northeast A ...
WILEY2021Aerodynamic study of a Hyperloop pod equipped with compressor to overcome the Kantrowitz limit
This paper describes an investigation of the aerodynamic performance of a Hyperloop pod equipped with an axial compressor using CFD simulation. The compressor is expected to reduce the drag if the operational speed of the pod exceeds the Kantrowitz Limit ( ...
2021Time-lapse high-resolution microscopy to study the morphogenesis of microorganisms
Mélanie Thérèse Marie Hannebelle
Mycobacterium tuberculosis, the etiological agent for the tuberculosis disease, is a bacterial pathogen thought to infect about a quarter of the global human population. It is the first cause of death among infectious diseases, and is most prevalent in low ...
EPFL2020Microfluidic Production of Capsules-in-Capsules for Programed Release of Multiple Ingredients
Capsules with thin shells have a high‐loading capacity and are thus well‐suited containers for reagents that must be stored in confined volumes. Capsules contained in larger capsules, so‐called double capsules, allow the encapsulation of distinct reagents ...
