Microfluidic Spinning of PEDOT:PSS Microfibers for Nerve Guidance Conduits

Advanced Materials Technologies, EarlyView.
This publication explores the fabrication of microfluidically spun PEDOT:PSS microfibers for conductive nerve guidance conduits (NGCs). It details the spinning process, fiber characterization, and biocompatibility assessment. The study highlights the fibers' mechanical and electrical properties, non‐cytotoxicity, and potential for nerve regeneration or

The relationship between chlorophyllous spores and mycorrhizal associations in ferns: evidence from an evolutionary approach

American Journal of Botany, Volume 109, Issue 12, Page 2068-2081, December 2022., 2022
Abstract Premise Approximately 14% of all fern species have physiologically active chlorophyllous spores that are much more short‐lived than the more common and dormant achlorophyllous spores. Most chlorophyllous‐spored species (70%) are epiphytes and account for almost 37% of all epiphytic ferns.

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts

Advanced Materials Technologies, EarlyView.
An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

Effects of simulated drought by PEG-6000 on the germination of Hopea chinensis seeds under different temperature conditions

Guangxi Zhiwu
Hopea chinensis is distributed in China and its seeds are typically reclacitrant. In order to investigate the germination adaptability of seeds to temperature and moisture, we carried out an experiment with three different constant temperatures (15, 20 ...

Seed Germination and Vigor

Annual Review of Plant Biology, 2012
Germination vigor is driven by the ability of the plant embryo, embedded within the seed, to resume its metabolic activity in a coordinated and sequential manner. Studies using “-omics” approaches support the finding that a main contributor of seed germination success is the quality of the messenger RNAs stored during embryo maturation on the mother ...

Selective Color Appearance of Liquid‐Crystal‐Aided Laser‐Induced Periodic Surface Structures

Advanced Optical Materials, EarlyView.
Self‐assembled nano trenches on transparent electrodes are produced by irradiating femtosecond laser, and then combined with liquid crystal, showing brilliant selective color, which is electronically switchable. The nano trenches diffract light, and those totally internally reflected light propagates in the liquid crystal cell.

A mathematical model for the germinal center morphology and affinity maturation [PDF]

arXiv, 2002
During germinal center reactions the appearance of two specific zones is observed: the dark and the light zone. Up to now, the origin and function of these zones are poorly understood. In the framework of a stochastic and discrete model several possible pathways of zone development during germinal center reactions are investigated.

Chemical AI in the Limelight: The Contribution of Photochromic Materials and Oscillatory Chemical Reactions

Advanced Optical Materials, EarlyView.
Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...

Physiological Response to Salinity Stress by Primed Seedsof Three Species of Lawn

Tulīd va Farāvarī-i Maḥṣūlāt-i Zirā̒ī va Bāghī, 2015
Salinity is one of the most important ecological stresses which have undesirable effects on seed germination. This study was carried out to evaluate the germination of three species of lawn (Poa pratensis, Lolium perenne, Cynodon dactylon) seeds under ...
