Phyllotaxis diversity in Lycopodium clavatum L. and Lycopodium annotinum L.

open access: yesActa Societatis Botanicorum Poloniae, 2014
In shoots of Lycopodium microphyllous phyllotaxis is extremely diverse. 24 various patterns were found in anisotomous L. clavatum and "only" 11 in isotomous L. annotinum. Spiral patterns expressed by k:(k+1 ) parastichy numbers were present together with

Magnetic and Dyed Microcapsules From the Spores of Clubmoss

open access: yesFrontiers in Physics, 2022
In this article we describe the preparation of bioavailable microcapsules derived from spores of clubmoss (Lycopodium clavatum) that are composed of protein-free, non-allergenic, and porous sporopollenin, often described as nature’s most robust polymeric

A Pollen‐Enhanced Bionic Mechanoreceptor Induced by Asymmetric Ionic Convection in Hydrogel for Sensory‐Augmented Prostheses

open access: yesAdvanced Science, EarlyView.
This work proposed a pollen‐enhanced bionic mechanoreceptor based on ionic convection. Leveraging the ion anchoring effect of the pollen particle, the output performance could be ∼12 times higher than the original state. By employing deep learning models as AI brains, the feasibility of a sensory‐augmented prosthesis consisting of a pollen‐enhanced ...
