University of Toronto professor turns hemp into auto parts

30.09.2003


If Mohini Sain has his way, cars of the future may be fitted with tough, durable and completely biodegradable bumpers made of hemp.



Sain, a professor in the University of Toronto’s Faculty of Forestry and Department of Chemical Engineering and Applied Chemistry, creates biocomposites from processed plant fibres. His latest research, published in the August issue of Materials Research Innovations and the July issue of Macromolecular Materials and Engineering, describes a way to create a material from hemp (a member of the cannabis family) that is both strong and lightweight. "We hope to develop this technology for automotive interior parts like instrument panels, structural applications for buildings and sports equipment and, ultimately, for medical devices such as cardiac devices and blood bags," says Sain.

In the studies, Sain treated stalks of hemp with chemicals to break down the "glue" that holds clumps of fibres together. The plant material was then combined with synthetic plastics. However, if it is mixed with plastics made from soy beans or pulp and paper sludge, researchers can create tough biocomposites that are completely biodegradable. Finally, using a combination of heat and pressure, they compressed the material into a variety of shapes. While these studies used hemp, the process also works with flax, wheat and corn.


Sain says these "green" materials could ultimately help Canada reduce its greenhouse gas emissions. "One of the greatest benefits of this technology is that we will not harm our environment by overproducing these natural fibres," says Sain. "It’s a step towards reducing petrochemical-based material consumption and living in a bio-based economy."

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
