Whole-cell response to nitrogen deprivation in the diatom Phaeodactylum tricornutum

Journal of Experimental Botany, 2015
Highlight An integrated transcriptomics and metabolomics analysis of the nitrogen-deprivation response in the diatom Phaeodactylum tricornutum uncovered remobilization of internal nitrogen-containing resources, and remodelling of carbon and lipid ...

Metalens‐Enabled Double‐Helix Point Spread Function for Multifunctional Imaging

Advanced Physics Research, EarlyView.
A single metalens is employed to generate a double‐helix point spread function (DH‐PSF). At the design wavelength, the PSF rotation angle varies linearly with depth, while the lobe spacing follows an inverse dependence on axial position. At a fixed depth, the lobe spacing further exhibits a linear dependence on wavelength due to dispersion.

Designer diatom episomes delivered by bacterial conjugation

Nature Communications, 2015
Eukaryotic microalgae hold great promise for the bioproduction of fuels and higher value chemicals. However, compared with model genetic organisms such as Escherichia coli and Saccharomyces cerevisiae, characterization of the complex biology and ...

Fear of grazing rivals the toxin‐inducing effects of nutrients in two marine harmful algae – a meta‐analysis

Biological Reviews, EarlyView.
ABSTRACT One of the major subfields of chemical ecology is the study of toxins and how they mediate interactions between organisms. Toxins produced by harmful algae (phycotoxins) impact a wide variety of organisms connected to the marine food web. Significant research efforts have thus aimed to identify the ecological and evolutionary drivers behind ...

Partners or passengers? Revisiting the association between diatoms and aquatic animals

Biological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Carbon‐Supported Dual‐Nickel Atom Catalysts With Stabilized Ni─N3 Active Sites for Efficient CO2 Electroreduction

Carbon Energy, EarlyView.
Dual‐nickel atom catalysts (Ni‐DACs) are developed to stabilize unsaturated Ni─N3 atomic sites by constructing N3Ni─NiN3 dual‐atom structures from coal. Benefiting from the modulated electronic structure that optimizes intermediate adsorption, Ni‐DACs outperform Ni‐SACs in CO2 electroreduction, achieving a max FECO of 98.6% at −0.8 V vs RHE and a TOF ...

Comparative analysis of organelle genomes provides conflicting evidence between morphological similarity and phylogenetic relationship in diatoms

Frontiers in Marine Science
Diatoms (Bacillariophyta) are abundant phytoplankton groups in marine environments, which contribute approximately 20% of global carbon fixation through photosynthesis.

Diatoms Green Nanotechnology for Biosilica-Based Drug Delivery Systems

Pharmaceutics, 2018
Diatom microalgae are the most outstanding natural source of porous silica. The diatom cell is enclosed in a three-dimensional (3-D) ordered nanopatterned silica cell wall, called frustule.

Tailoring Se‐Mediated Co‐Co Dual‐Atom Sites for Oxygen and Iodide Electrocatalysis Toward High‐Efficiency and Ultradurable Zinc‐Air/Iodide Hybrid Batteries

Carbon Energy, EarlyView.
A Se‐mediated Co dual‐atom catalyst replaces sluggish oxygen evolution with efficient iodide oxidation in zinc‐air/iodide hybrid batteries. Se‐induced d‐p orbital hybridization optimizes adsorption, enabling a low 0.365 V voltage gap and superior durability, fundamentally overcoming conventional kinetic bottlenecks.
