Epiphytic diatoms of the Tisza River, Kisköre reservoir and some oxbows of the Tisza River after the cyanide and heavy metal pollution in 2000 [PDF]

, 2005
The Tisza River is a large tributary of the Danube River. The largest reservoir of the river is the Kisköre reservoir, and there are furthermore a great number of oxbows in the vicinity of the river.

Beyond the Oxo‐Wall: Synthesis and Reactivity of a Six‐Coordinate Formally CoIV‐Oxo Complex

Angewandte Chemie, EarlyView.
We present the first example of a six‐coordinate formally Co(IV)‐oxo complex, [Co(TQA)(O)(OH)]+ (1), which exists as an admixture of CoIV‐oxo and CoIII‐oxyl resonance structures. Complex 1 is capable of performing oxygen atom transfer reactions and abstracting moderately strong hydrogen atoms at rates faster than other characterized CoIV‐oxo compounds.

Sub‐Diffraction and Irreversibly Tunable Imaging With Potato Starch Lenses

Advanced Optical Materials, EarlyView.
Native potato starch granules function as sustainable birefringent microlenses that enable polarization‐controlled conventional and vortex lensing via spin‐to‐orbital angular momentum conversion. They provide sub‐diffraction and spiral‐contrast imaging, support vortex‐array generation with controllable topological‐charge sign, exhibit irreversible ...

Applications of Diatoms as Potential Microalgae in Nanobiotechnology

BioImpacts, 2012
Introduction: Diatoms are single cell eukaryotic microalgae, which present in nearly every water habitat make them ideal tools for a wide range of applications such as oil explora­tion, forensic examination, environmental indication, biosilica pattern ...

Cell‐Based Biohybrid Micro/Nanorobots for Biotherapy

Advanced Robotics Research, EarlyView.
This review systematically evaluates cell‐based biohybrid micro/nanorobots (CB‐BMRs), highlighting their cell selection criteria, fabrication strategies, and diverse actuation modes. Furthermore, it surveys the promising therapeutic applications of CB‐BMRs in targeted cancer, thrombosis, and inflammation treatments, while comprehensively discussing ...

High‐Throughput Screening and Interpretable Machine Learning for Rational Design of Bimetallic Catalysts for Methane Activation

Advanced Science, EarlyView.
ABSTRACT Methane's efficient catalytic removal is vital for sustainable development. Bimetallic catalysts, though promising for methane activation, pose a design challenge due to their complex compositional space. This work introduces an integrated framework that combines high‐throughput density functional theory (DFT) and interpretable machine ...

Auxosporulation in Paralia guyana MacGillivary (Bacillariophyta) and Possible New Insights into the Habit of the Earliest Diatoms.

PLoS ONE, 2015
BACKGROUND:Diatoms are one of the most ecologically important aquatic micro-eukaryotes. As a group unambiguously recognized as diatoms, they seem to have appeared relatively recently with a limited record of putative remains from oldest sediments.

Culturing Diatoms

, 2023
In this chapter, we provide information on cultures of diatoms, starting with a brief introduction of the history of diatom culture collections. We present a synopsis of diatom strains currently available in culture collections and their representation in terms of habitat diversity, geographical distribution, phylogeny and taxonomic diversity.
