Effects of Growth Media on the Diversity of Culturable Fungi from Lichens

open access: yesMolecules, 2017
Microscopic and molecular studies suggest that lichen symbioses contain a plethora of associated fungi. These are potential producers of novel bioactive compounds, but strains isolated on standard media usually represent only a minor subset of these ...

Interfacial Bioengineering of Dynamic Networks Hybrid Hydrogel for Programmed Intervention in Oral Precancerous Epithelial States

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops a dual‐bioinspired hydrogel, MSA@PGel (macrophage membrane‐coated and salvianolic acid B/5‐aminolevulinic acid co‐loaded liposomes embedded in a polydopamine‐based gel), that integrates macrophage membrane‐mediated active targeting and mussel‐inspired wet adhesion for programmed intervention in oral precancerous lesions.

Endolichenic fungi: the lesser known fungal associates of lichens

open access: yesMycology, 2017
Lichens are the result of a stable mutualism between a fungal and a photosynthesising partner (alga or cyanobacterium). In addition to the fungal partner in this mutualism, lichens are associated with endolichenic fungi which reside inside their thalli ...

Harnessing Transformation of Metal‐Ligand Coordination in Dinuclear Ni(II)‐Schiff Base Coordination Polymer for Promoting Electrochemical Oxygen Evolution

open access: yesAdvanced Science, EarlyView.
Ni–Schiff base coordination polymer [Ni2(tmd)2]n was synthesized and applied to enhance alkaline OER by virtue of its transformation between 5‐ and 6‐coordinate Ni sites along with the spin state exchange. ABSTRACT One of the major challenges in overall water splitting is improving the sluggish kinetics of the anodic oxygen evolution reaction (OER ...
