Summary
Sustainably managed Japanese forest biomass can replace mined materials in electrochemical energy devices. This approach supports biodiversity and regional economies by utilizing underused satoyama resources.
Area of Science:
- Materials Science
- Environmental Science
- Electrochemistry
Background:
- Global forest overuse is a concern, while Japan faces secondary forest underuse, degrading satoyama ecosystems.
- Electrochemical energy technologies heavily rely on mined graphite and precious metals.
Purpose of the Study:
- To investigate the feasibility of using sustainably managed satoyama biomass as a carbon feedstock for electrochemical energy storage and conversion.
- To analyze structure-property-performance relationships of wood-derived carbons in various electrochemical applications.
Main Methods:
- Focus on wood-derived and satoyama-relevant carbons.
- Evaluation in batteries, supercapacitors, electrocatalysis, and bioelectrochemical systems.
- Linking forest management (coppicing, thinning) with carbonization and device fabrication.
Main Results:
- Satoyama biomass can function as activated carbons, hard carbons, graphitized carbons, and catalyst supports.
- Feasibility demonstrated, but bottlenecks in feedstock variability, volumetric performance, standardization, and scale-up exist.
Conclusions:
- Underused satoyama biomass is a viable carbon feedstock for electrochemical applications.
- This framework can reduce mining dependence, promote biodiversity, and support regional material cycles.

The microbial conversion of organic matter into biofuels holds potential as a renewable energy source. Among biofuel sources, microalgae are recognized as a highly efficient and adaptable feedstock for biodiesel production, owing to their rapid biomass accumulation, elevated lipid productivity, and capacity to proliferate in diverse aquatic systems, including freshwater, marine, and wastewater habitats. Unlike terrestrial crops, microalgae do not compete for land and can achieve significantly...

Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side...

01:14The Carbon Cycle
32.8K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

2.7K
Electrodeposition is a technique used to separate an analyte from interferents by electrochemical processes. Here, the analyte is a metal ion that can be deposited on an electrode immersed in the sample solution. The electrochemical setup consists of an anode and a cathode. When an electric current is applied to the setup, oxidation occurs at the anode. At the cathode, which consists of a large metal surface, metal ions undergo reduction and deposit onto the surface.

In humans, the photoreceptor cells of the eye and sensory hair cells of the ear lack stem cells. These cells are thus unrenewable and cannot be replaced when they are damaged or destroyed.
Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of...
