The effect of the duration of hypoxia on phenolic accumulation in roots of clonal Eucalyptus marginata and their subsequent infection with Phytophthora cinnamomi [PDF]

, 1997
Roots of E. marginata exposed to hypoxia show increased resistance to infection by P. cinnamomi. A more rapid production of phenolics has previously been shown to be related to increased resistance in clonal E. marginata.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics

Advanced Functional Materials, EarlyView.
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Chemical composition, antinociceptive and free radical-scavenging activities of geopropolis from Melipona subnitida Ducke (Hymenoptera: Apidae: Meliponini)

Sociobiology, 2014
Like many stingless bee species, Melipona subnitida Ducke uses geopropolis (a mixture of wax, plant resins, pollen grains and mud) for sealing small crevices in their nest cavities, in order to avoid the entry of air, and for defense against pathogenic ...

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

Advanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...
