IIT Mandi researchers comes up with a technique for generating electricity by walking on roads

New Delhi :
Researchers of Indian Institute of Technology, Mandi (IIT Mandi) have come up with a technique of building roads with Piezoelectric Materials to generate electricity on simple human walking. Using these materials, the weight from vehicles can also power up the road lights & traffic signals.

What are Piezoelectric Materials? –

Piezoelectric materials are materials that have the ability to generate internal electrical charge from applied mechanical stress. The term piezo is Greek for “push.” Materials that exhibit the piezoelectric effect also demonstrate the inverse piezoelectric effect (also called the reverse or converse piezoelectric effect). The inverse piezoelectric effect is the internal generation of mechanical strain in response to an applied electrical field.

Proposed the idea of using these piezoelectric materials –

The researchers have been studying and finding piezoelectric materials that can convert mechanical energy into electrical energy. After the research, they have proposed the idea of using these piezoelectric materials in floor tiles to build the roads, which will generate electricity on human walking. Also, the weight from vehicles can power up the road lights and traffic signals.

They are extending their work further for a more accurate –

Dr. Rajeev Kumar, Associate Professor, IIT Mandi, explains, “Piezoelectric materials can generate electrical energy when a force is applied on them, and are thus extremely useful.” Electricity production by these materials is limited in use and their applications yet. According to the researchers, Piezoelectric materials can do the reverse as well – generate mechanical motion in response to electrical energy. Moreover, they are extending their work further for a more accurate prediction of the effects of the proposed ‘poling technique’ on the mechanical properties of the material, which will give better insights into providing the services of this technique in real-life applications. The results of their work have been published in the journal Engineering Reports.

IIT Roorkee prof study finds Fbln7-C can delay programming process

New Delhi :
A study by Indian Institution of Technology, Roorkee (IIT Roorkee) professor Pranita Sarangi has found that Fbln7-C can delay the reprogramming process of macrophages present in the tumor tissues, also known as tumor associated macrophages (TAMs), while directly inhibiting the proliferation of cancer cells. This study will be useful for oncological & immunological cancer research & designing therapeutics.

This study used various in vitro systems –

IIT Roorkee As the cancer progress, the macrophages that are initially recruited into the cancer site to assist in the removal of the cancer cells get reprogrammed to produce certain protein substances that help the cancers to grow and spread to different parts of the body. This study used various in vitro systems and an animal breast tumor model to highlight that Fbln7-C could help the macrophages to resist the reprogramming process and delay the conversion of anti-tumorigenic to pro-tumorigenic TAMs, while directly inhibiting the proliferation of cancer cells.
