The discovery of a novel enzyme that releases a valuable chemical from agricultural waste could provide an important breakthrough in the upscaling of renewable fuels and chemicals, a new study shows.
Researchers – led by the University of York - have discovered an enzyme in a fungus that can act as a catalyst to bring about a biochemical reaction that breaks down lignocellulose to produce chemicals and fuels.
The Hemp plant has 50,000 different known uses to replace products we use on a daily basis. It is a renewable resource that yields a harvest in 4 to 5 months' time. Let’s list the many things that Hemp is for our people.
Hemp is energy
Hemp biomass can create biofuels such as gasoline, methane, ethanol, and methanol. Hemp can also be used to create electricity. It is a cleaner-burning fuel than of fossil fuels and is a renewable resource that can be harnessed by all people in all places.
Hemp is building materials
Hemp biomass can be used to create hempcrete, hemp insulation, and hemp wood. Hemp is more thermally efficient, fireproof & less susceptible to mold and mildew providing significant sound absorption. One acre of Hemp is equal to up to 4 acres of trees in fiber production
Hemp is economic diversification and development for our planet
The Hemp industry will create a new economy that is plant-based. It provides the answers we have been looking for about how we can stop the pollution that is causing the extinction of wildlife and polluting our oceans, land, and air. It is a new opportunity to give the power back to people to create a self-sustainable future for themselves out of Hemp.
At Linköping University, Sweden, scientists have designed a stable, highly conductive polymer ink. The breakthrough opens the door for novel printed electronics with high energy efficiency.
The study findings have been published in the Nature Communications journal.
Electrically conducting polymers have enabled the growth of lightweight and flexible electronic components like batteries, transistors, light-emitting diodes, solar cells, and organic biosensors.
The electrical properties of such polymers can be tweaked with the help of a technique called “doping.” This technique involves adding several dopant molecules to the polymer to alter its properties. Based on the dopant, the doped polymer has the ability to conduct electricity by the motion of either positively charged holes (a “p-type” conductor) or negatively charged electrons (an “n-type” conductor).
Currently, the p-type conductor PEDOT:PSS is the most common conducting polymer in use. PEDOT:PSS exhibits various convincing features like excellent ambient stability, high electrical conductivity, and most significantly, commercial availability as an aqueous dispersion.
But several electronic devices need a combination of n-types and p-types to function. Right now, there is no n-type comparable with PEDOT:PSS.
Scientists at Linköping University, together with their collaborators from the United States and South Korea, have designed a conductive n-type polymer ink that remains stable in air and even at higher temperatures. This new polymer formulation is called BBL:PEI.
According to Simone Fabiano, senior lecturer in the Department of Science and Technology at Linköping University, “This is a major advance that makes the next generation of printed electronic devices possible. The lack of a suitable n-type polymer has been like walking on one leg when designing functional electronic devices. We can now provide the second leg.”
The latest n-type material is available in the form of ink along with ethanol as the solvent. The ink can be deposited by just spraying the solution onto a surface, which makes organic electronic devices simpler and inexpensive to manufacture.
Moreover, the ink is highly environmentally friendly compared to several other n-type organic conductors that are being developed at present, which contain detrimental solvents. Simone Fabiano is confident that the technology is all set for regular use.
The study was financially supported by the Knut and Alice Wallenberg Foundation, the Swedish Research Council, the Åforsk Foundation, the Olle Engkvist Foundation, Vinnova, and the strategic research area Advanced Functional Materials at Linköping University.

The automaker has said that only electrified vehicles will be rolled out in North America.
Honda has announced its key target plans for the sale of electric and fuel cell electric vehicles (FCEVs) in North America. It intends to make those zero-emission vehicles the only type of vehicles they sell by 2040.
Battery electric and FCEVs will represent 100 percent of Honda’s sales by that year, said the plan.
According to Honda’s timeline for rolling out its zero-emission vehicles, the first major target will be in 2030. By that year, it already expects 40 percent of the vehicles it sells to be electric or fuel cell electric vehicles. Five years later in 2035, that percentage will double to 80 percent of the total vehicles it sells per year. Then, after another five years have passed, in 2040, 100 percent of new Honda vehicle sales in North America will be zero-emission producers.
The automaker sees FCEV technology as a strong component of the complete solution toward decarbonizing transportation. The challenge to achieve carbon neutrality will involve the use of H2, according to the company’s view. They anticipate that hydrogen will rapidly become a considerably more widely adopted renewable energy and fuel source.
The company has stated that they would be leaving Formula 1 (F1) at the close of this year’s season in order to focus on the development and production of fuel cell and battery technologies. Honda has been involved in the research and development of hydrogen fuel and fuel cell technologies, as well as their commercialization. Moreover, it has kept up its collaboration with General Motors with the goal of slashing the cost of producing and using this renewable energy technology.
The automaker has also shared its aims to bring about an H2 powered society by broadening its fuel cell electric vehicle lineup and by using this type of system for an expanded range of applications. This includes everything from passenger vehicles to commercial trucks, in addition to both mobile and stationary power sources.

First Aberdeen and Aberdeen City Council are celebrating this week after their Wrightbus hydrogen double-decker bus fleet notched up its first major milestone of operation.
Since launch in January, the fleet of 15 UK-manufactured Wrightbus buses, has already saved a huge 170,000kg of CO2 from being released into the atmosphere – equivalent of taking 42 cars off the road for a year – a significant improvement in the city’s air quality for its residents.
Michelle Thomson, a hydrogen bus driver at First Aberdeen, said: “Drivers and the public love the new hydrogen buses – sailing smoothly and silently through the city’s streets is a joy."
Knowing a Wrightbus hydrogen bus is not polluting the atmosphere makes it a ride of kudos, as we come together to tackle the climate emergency.
“The buses are so quiet that socially distancing passengers wearing masks can still have a natter from either end of the bus. As drivers, it makes us much more in tune with what’s going on on board, so we’re able to deliver the best in customer service." said Michelle.

Technically a nut, hemp seeds are very nutritious. They have a mild, nutty flavor and are often referred to as hemp hearts. Hemp seeds contain over 30% fat. They are exceptionally rich in two essential fatty acids, linoleic acid (omega-6) & alpha-linolenic acid omega-3
While the fat content in hemp seeds comes primarily from its healthy essential fatty acids, eat them in moderation to meet your recommended daily consumption of fat. Hemp seeds may interact with certain medications including anticoagulants.
