Evolution of wind turbine over the years

Image
  Evolution of wind turbine heights and outputs.: For conventional generators, such as a coal plant, a megawatt of capacity will produce electricity that equates to about the same amount of electricity consumed by 400 to 900 homes in a year. https://lnkd.in/gyMsFXxf In the near future, one wind turbine can power 5200-13,500 homes!

Indian EV passenger vehicle quarterly sales in Q1-2022

Image
Indian EV passenger vehicle mass-market has posted the highest-ever quarterly sales in Q1-2022. This is largely contributed by Tata products namely – Nexon EV and Tigor EV. The introduction of the right BEV products at the right price is fueling the EV demand in India. With a 95% market share, Tata continues to be the market leader with the right product at the right price, way ahead of competitors. Tata Nexon EV has even outsold Nexon diesel in 2022!

UBC team discovers ‘silver bullet’ to keep medical devices free of bacteria

Image
University of British Columbia researchers have found a ‘silver bullet’ to kill bacteria and keep them from infecting patients who have medical devices implanted. The team from UBC and the Vancouver Coastal Health Research Institute has developed a silver-based coating that can easily be applied to devices such as catheters and stents. Their novel formulation, discovered by screening dozens of chemical components, overcomes the complications of silver that have challenged scientists for years. “This is a highly effective coating that won’t harm human tissues and could potentially eliminate implant-associated infections. It could be very cost-effective and could also be applicable to many different products,” said Dr. Jayachandran Kizhakkedathu (he/him), professor in UBC’s department of pathology and laboratory medicine, Centre for Blood Research and Life Sciences Institute and co-senior author of the study published today in ACS Central Science. Implanted medical devices can save lives

how processing conditions are impacting crystallinity and as a consequence the performance of plastic parts.

  🔥Rule of thumb post - how processing conditions are impacting crystallinity and as a consequence the performance of plastic parts. Crystallinity only plays a role with semi-crystalline polymers such as polyamides and polyolefins. High-density polyethylene can achieve crystallinity levels of 85% and ranges among the polymers with the highest crystallinity. Allover, for most semi-crystalline polymers crystallinity, ranges below 50%. 📌Mechanism of crystallinity The main drivers for crystallinity are time and temperature. The formation of crystallinity starts below the melting point and stops below the glass transition area. As long the material is above the glass transition point, molecule mobility is given to form regions of crystallinity within the amorphous regions. Therefore, the most effective temperature window is below the melting point and above the glass transition point. Crystal formation and growth vary for each semi-crystalline polymer and there is an optimum temperature f

Sumitomo Chemical’s New Facility to Commercialize Sustainable Polyolefin

Image
  Sumitomo Chemical completed the construction at its Chiba Works (Ichihara, Chiba, Japan) of a pilot facility to manufacture ethylene using renewable ethanol as a raw material. The Company will verify an ethylene manufacturing technology at this new facility to commercialize polyolefin products that are environmentally sustainable and compatible with a circular economy and will provide samples to develop the market, with the aim of contributing to creating a circular economy. Plastics such as polyolefin are essential materials for everyday life and are widely used in a variety of applications, such as automobiles, electronic devices, and packages and containers. Meanwhile, it has become a pressing global issue to recycle plastic products made from fossil resources and reduce the greenhouse gas emissions generated over their lifecycle, from production to disposal after use. Circular Economy Initiatives The new pilot facility at Chiba Works will produce ethylene from ethanol produced fr

Scientists discover how salt in tumors could help diagnose and treat breast cancer

Image
  Analyzing sodium levels in breast cancer tumors can give an accurate indication of how aggressive a cancer is and whether chemotherapy treatments are taking effect, new research has shown. In a study, by the universities of York and Cambridge and funded by charities Cancer Research UK and Breast Cancer Now, researchers developed a technique using sodium  magnetic resonance  imaging (MRI) to detect salt levels in  breast cancer tumors  in mice. Using this technique, the researchers looked at  breast cancer  tumors and discovered that salt (sodium) was being accumulated inside  cancer cells  and that more active tumors accumulate more sodium. The researchers then took a group of 18 tumors and targeted some of them with chemotherapy treatment. When they scanned the tumors a week later they found that  sodium levels  had reduced in the tumors treated with chemotherapy. There are currently around 55,920 new cases of breast cancer diagnosed in the UK each year and it is the leading cause o

TGA

Image
  Thermogravimetric analysis (TGA) is a common thermal analysis technique that provides composition information for polymeric materials. Most often, we associate TGA with quantitative data. However, I was reminded during a recent material analysis that TGA can also provide insight into the qualitative analysis. I was analyzing a rubber O-ring. My first test, as usual, was Fourier transform infrared spectroscopy (FTIR). The FTIR indicated that the material was a nitrile rubber (NBR) compound. Additional absorption bands associated with aluminum silicate clay were also present. Weak bands indicated an ester-based plasticizer. The general form of the spectrum was suggestive of a moderate loading of carbon black. I conducted the TGA analysis and found all of the expected weight loss events for the quantification of the plasticizer, polymer, and carbon black, as well as the residue for the mineral filler. However, one additional weight loss stood out. A weight loss of 4.4% centered at appro

Study shows everyday plastic products release trillions of microscopic particles into water

Image
Plastics surround us, whether it's the grocery bags we use at the supermarket or household items such as shampoo and detergent bottles. Plastics don't exist only as large objects, but also as microscopic particles that are released from these larger products. These microscopic plastics can end up in the environment, and they can be ingested into our bodies. Now, researchers at the National Institute of Standards and Technology (NIST) have analyzed a couple of widely used consumer products to better understand these microscopic plastics. They found that when the plastic products are exposed to hot water, they release trillions of nanoparticles per liter into the water. The NIST researchers published their findings in the scientific journal Environmental Science and Technology. "The main takeaway here is that there are plastic particles wherever we look. There are a lot of them. Trillions per liter. We don't know if those have bad health effects on people or animals. We
