Home > Spotlight September 2021: Wood, the raw material of the future?

One of the greatest challenges facing humanity is to produce clean drinking water under the given circumstances of global warming, population growth and increasing littering. In September, we would like to present a review article that believes one approach to solve this problem is the use of nanoscale wood. In the review, “Advanced Nanowood Materials for the Water-Energy Nexus,” published in the journal Advanced Materials, methods for using wood for water treatment are outlined based on the structure of wood, bottom up or top down. Using the approaches described, wood can be used for water purification, desalination, or chemical removal.
Many examples are shown of how the basic building block of wood, cellulose (a natural polymer), can be processed into nanofibers or polymer matrices, enabling filtration of ultra-small particles.
In contrast, top-down approaches preserve the fundamental structure of wood. For example, naturally occurring channels and mesopores open up the possibility of binding chemicals or applying catalysts. Research with palladium, titanium dioxide, or iron oxide nanoparticles applied to wood showed very good separation of chemicals from water. By chemically modified wood, it was possible to selectively remove copper ions, separate oils and organic solvents, or filter out heavy metals from water.
Wood is an indispensable, climate-neutral raw material due to its ability to bind CO2. In combination with nanoparticles, it may be possible in the future to extend the versatile properties of wood and thus provide a solution approach to water scarcity and environmental pollution.

Spotlight September: A methodology for the automatic evaluation of data quality and completeness of nanomaterials for risk assessment purposes

This paper describes a method for automatically assessing the quality and completeness of nanosafety data for the purpose of risk assessment. Steps to develop the methodology for assessing data completeness and the methodology for assessing quality are presented. The methodology is tailored to physicochemical and hazard (meta) data, but can also be configured with appropriate […]

Spotlight February 2022: Probabilistic risk assessment – the keystone for the future of toxicology

The basics of toxicology are constantly being reconsidered, and the approach to risk assessment is therefore constantly being put to the test, because, as William Osler is cited in this publication, “Medicine (toxicology) is a science of uncertainty and an art of probability“. In this recent paper, the team around Thomas Hartung (Johns-Hopkins University/University of […]
