Confinement-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 ...

In 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 ...

Variations of intracellular density during the cell cycle arise from tip-growth regulation in fission yeast

Emrah Bostan, Pascal Damian Odermatt

Intracellular density impacts the physical nature of the cytoplasm and can globally affect cellular processes, yet density regulation remains poorly understood. Here, using a new quantitative phase imaging method, we determined that dry-mass density in fis ...

Anion Selection Criteria for Water-in-Salt Electrolytes

Corsin Battaglia, David Reber, Maximilian Becker

Water-in-salt electrolytes have enabled the development of novel high-voltage aqueous lithium-ion batteries. This study explores the reasons why analogous sodium electrolytes have struggled to reach the same level of electrochemical stability. Solution str ...

Automated phenotyping of Caenorhabditis elegans embryos with a high-throughput-screening microfluidic platform

Martinus Gijs, Matteo Cornaglia, Raphaël Etienne Jean Trouillon, Hüseyin Baris Atakan, Tunç Alkanat

The nematode Caenorhabditis elegans has been extensively used as a model multicellular organism to study the influence of osmotic stress conditions and the toxicity of chemical compounds on developmental and motility-associated phenotypes. However, the sev ...

Triboelectric effect to harness fluid flow energy

Danick Briand, Rubaiyet Iftekharul Haque, Amr Yehia Hussien Mahmoud Arafat

We are reporting energy scavenging from fluid flows inside tubular structures using triboelectric effects. Two separate designs of triboelectric generators are proposed. A tubular design that uses liquid-solid interaction mechanism for water, and freestand ...

Guanidinium can both Cause and Prevent the Hydrophobic Collapse of Biomacromolecules

Halil Ibrahim Okur

A combination of Fourier transform infrared and phase transition measurements as well as molecular computer simulations, and thermodynamic modeling were performed to probe the mechanisms by which guanidinium (Gnd(+)) salts influence the stability of the co ...

To What Extent Do Food Preferences Explain the Trophic Position of Heterotrophic and Mixotrophic Microbial Consumers in a Sphagnum Peatland?

Edward Mitchell, Vincent Eric Jules Jassey, Caroline Meyer

Although microorganisms are the primary drivers of biogeochemical cycles, the structure and functioning of microbial food webs are poorly studied. This is the case in Sphagnum peatlands, where microbial communities play a key role in the global carbon cycl ...

On the Thermodynamics of Framework Breathing: A Free Energy Model for Gas Adsorption in MIL-53

Berend Smit

When adsorbing guest molecules, the porous metal-organic framework MIL-53(Cr) may vary its cell parameters drastically while retaining its crystallinity. A first approach to the thermodynamic analysis of this "framework breathing" consists of comparing the ...
