Advanced Materials, EarlyView.As‐spun carbon materials produced from Lignosulfonate, gelatin, and alginate, selected for water solubility, and ability to produce templated sustainable carbon nanostructures. Gelatin and alginate are sacrificial during thermal processing, allowing the production of engineered high surface area nanostructures, which are further characterized for ...

Gelechiidae Moths Are Capable of Chemically Dissolving the Pollen of Their Host Plants [PDF]
, 2011 Background: Many insects feed on pollen surface lipids and contents accessible through the germination pores. Pollen walls, however, are not broken down because they consist of sporopollenin and are highly resistant to physical and enzymatic damage. Here

Collapsing pollen grains [PDF]
, 2019 Pollen grains come in all sorts of shapes - they can be spherical, ellipsoidal, lobate, prismatic, polyhedral, and then, there are some which escape easy qualification in terms of geometry. The sizes also differ very much, from less than 10 micrometers (e.g.

Pollen dimorphism and androgenesis in Hordeum vulgare
Acta Societatis Botanicorum Poloniae, 2014 Dimorphism of binucleate pollen grains of Hordeum vulgare has been confirmed. It is considered, however, in contrast to the accepted opinions, that some of the large pollen grains with dense cytoplasm lying close to the tapetum are the outset forms for ...

Segmenting 20 Types of Pollen Grains for the Cretan Pollen Dataset v1 (CPD-1)
Applied Sciences, 2021 Pollen analysis and the classification of several pollen species is an important task in melissopalynology. The development of machine learning or deep learning based classification models depends on available datasets of pollen grains from various plant

Agent-Based Modeling of Pollen Competition [PDF]
, 2018 Non-random mating in Arabidopsis Thaliana is, at least in part, due to intense competition between pollen grains to fertilize the limited number of ovules.

Multifunctional Bracts in the Dove Tree Davidia involucrata (Nyssaceae:Cornales) [PDF]
, 2008 Although there has been much experimental work on floral traits that are under selection from mutualists and antagonists, selection by abiotic environmental factors on flowers has been largely ignored.
