A novel proposition for a citrate-modified photo-Fenton process against bacterial contamination of microalgae cultures

César Pulgarin, Christian Ludwig, Stefanos Giannakis, Adrian Pulgarin, Dominik Refardt

This study reports the first attempt of a citrate-modified photo-Fenton (PF) application at near-neutral pH (7.5–8.5, tap water) to disinfect Escherichia coli (as model bacterium), in Chlorella vulgaris cultures. The conditions are aimed towards bacterial ...

Reconstruction of image sequences from ungated and scanning-aberrated laser scanning microscopy images of the beating heart

Michael Stefan Daniel Liebling, Olivia Mariani

Fluorescence laser-scanning microscopy is a well-established imaging technique in biology, available in many imaging facilities to investigate structures within live animal embryos such as zebrafish. Laser scanning microscopes (LSM) are limited when used t ...

Imaging cellular ultrastructures using expansion microscopy (U-ExM)

Michaël Unser, Davide Gambarotto, Paul Guichard, Virginie Hamel, Denis Fortun

Determining the structure and composition of macromolecular assemblies is a major challenge in biology. Here we describe ultrastructure expansion microscopy (U-ExM), an extension of expansion microscopy that allows the visualization of preserved ultrastruc ...

Microsphere-assisted microscopy allows the limit of the diffraction of light to overcome while being non-invasive, full-field, label-free, and easy-to-implement. However, the observation of translucent samples remains difficult using a classical bright-fie ...

Neuronal morphology, long-distance transport and signalling critically depend on the organization of microtubules in the cytoskeleton. Second harmonic generation (SHG) imaging has been recognized as a potentially powerful tool for in situ label-free neuroi ...

We apply a high-resolution interference microscope with spectral resolution to investigate the scattering response of isolated meta-atoms in real space. The final meta-atoms consist of core-shell clusters that are fabricated using a bottom-up approach. The ...

Improved Alkali Intercalation of Carbonaceous Materials in Ammonia Solution

László Forró, Bálint Náfrádi, Péter Szirmai, Ferenc Simon, Bence Gábor Márkus, Sándor Kollarics

Alkali-intercalated graphite compounds represent a compelling modification of carbon with significant application potential and various fundamentally important phases. The intercalation of graphite with alkali atoms (Li and K) using liquid ammonia solution ...

Impact of iron reduction on the metabolism of Clostridium acetobutylicum

Vassily Hatzimanikatis, Karin Lederballe Meibom, Zhaleh Hosseini, Cornelia List

Iron is essential for most living organisms. In addition, its biogeochemical cycling influences important processes in the geosphere (e.g., the mobilization or immobilization of trace elements and contaminants). The reduction of Fe(III) to Fe(II) can be ca ...

In the last few years, ecofriendly malic acid production has received a potential platform for the bio-based chemicals to replace the dependency of fossil based resources. The main goal of this paper is to explore the feasibility of efficient production of ...

Compact lensless digital holography

Manon Rostykus

Microscopy is of high interest for biology since it allows imaging features that are too small to be seen with naked eyes. However, cells are mostly transparent to visible and infrared light which makes it difficult to see with a traditional microscope. To ...
