Researchers at Politecnico di Torino, BRIN in Indonesia, the Italian Institute of Technology (IIT) and University of Cagliari have recently introduced new composite hydrogel inks based on natural and environment friendly materials, which could be used to 3D print objects. These hydrogels, presented in a paper published in Sustainable Materials and Technologies, are based on acrylated-carboxymethyl cellulose (mCMC).

“We have been working on the development of new printable materials and functional devices since 2015, so in these years different areas were explored, resulting in many publications in the field of 3D printing,” Ignazio Roppolo, one of the researchers who carried out the study, told TechXplore.

The first objective of the work by Roppolo and his colleagues was to develop polymeric hydrogels for 3D printing that are based on natural resources, to increase sustainability and reduce the use of standard synthetic resins. In recent years, the team has been collaborating with Dr. Athanasia Amanda Septevani, a researcher at BRIN’s Research Center for Environment and Clean Technology in Indonesia.

Musk’s focus on asking and answering the right questions has played a major role in the Tesla CEO’s success, as recently reported by Inc.com. With the billionaire’s net worth floating around $200 billion, even critics have to admit that a few different factors put Musk in that position, and his business savvy is definitely one of them.

Beyond being a founder of both Tesla and SpaceX, Musk’s brands have increased mainstream awareness of both EVs, a necessary step forward for the climate, and for space exploration, a huge and growing industry, for lack of a better description.

But asking the right questions is central to Musk’s ethos as a CEO, and he’s revealed this time and time again. Musk’s leadership style has discouraged the chain of command mentality in favor of the free flow of information, and he has used this to encourage anyone to search for the right questions at the right times — a strategy crucial to Musk’s approach.

Plastic bottles, punnets, wrap – such lightweight packaging made of PET plastic becomes a problem if it is not recycled. Scientists at Leipzig University have now discovered a highly efficient enzyme that degrades PET in record time. The enzyme PHL7, which the researchers found in a compost heap in Leipzig, could make biological PET recycling possible much faster than previously thought. The findings have now been published in the scientific journal “ChemSusChem” and selected as the cover topic.

One way in which enzymes are used in nature is by bacteria to decompose plant parts. It has been known for some time that some enzymes, so-called polyester-cleaving hydrolases, can also degrade PET. For example, the enzyme LCC, which was discovered in Japan in 2012, is considered to be a particularly effective “plastic eater”. The team led by Dr Christian Sonnendecker, an early career researcher from Leipzig University, is searching for previously undiscovered examples of these biological helpers as part of the EU-funded projects MIPLACE and ENZYCLE. They found what they were looking for in the Südfriedhof, a cemetery in Leipzig: in a sample from a compost heap, the researchers came across the blueprint of an enzyme that decomposed PET at record speed in the laboratory.

The researchers from the Institute of Analytical Chemistry found and studied seven different enzymes. The seventh candidate, called PHL7, achieved results in the lab that were significantly above average. In the experiments, the researchers added PET to containers with an aqueous solution containing either PHL7 or LCC, the previous leader in PET decomposition. Then they measured the amount of plastic that was degraded in a given period of time and compared the values with each other.

Power-hungry, fossil-fuel dependent Japan has successfully tested a system that could provide a constant, steady form of renewable energy, regardless of the wind or the sun.

For more than a decade, Japanese heavy machinery maker IHI Corp. has been developing a subsea turbine that harnesses the energy in deep ocean currents and converts it into a steady and reliable source of electricity. The giant machine resembles an airplane, with two counter-rotating turbine fans in place of jets, and a central ‘fuselage’ housing a buoyancy adjustment system. Called Kairyu, the 330-ton prototype is designed to be anchored to the sea floor at a depth of 30–50 meters (100−160 feet).

Tested in one of the world’s strongest ocean currents, a prototype generator could herald the start of a new stream of renewable energy.

Lycopene, which makes fruits and vegetables such as tomatoes red, improves the efficiency of perovskite solar cells.

Tesla CEO #elonmusk has said that his company will not put a manufacturing plant in India until it is first allowed to sell, and service imported Tesla cars in the country. When a Twitter asked Musk about #Tesla’s plans to put up a manufacturing plant in India, #Musk responded, “Tesla will not put a manufacturing plant in any location where we are not allowed first to sell and service #cars.”

#India and Telsa haven’t reached an understanding regarding import duties and setting up of the manufacturing plant by Tesla in the #country.

Many criticisms have been leveled against Elon Musk—that he’s part of the elite, that Tesla has been the beneficiary of government handouts and exemptions, that his transhumanist Neuralink is a brain-data-mining operation. Yet his planned purchase of Twitter, his supposed free-speech absolutism, and his subsequent renunciation of the Democratic Party as “the party of hate” have put Musk squarely in the crosshairs of the woke cartel.

Vitriolic Twitter storms, a New York Times-Financial Times biographical exposé, a slew of hit pieces and scaremongering segments in the legacy media, and allegations of sexual harassment have dogged the automobile magnate ever since his Twitter bid. In response, Musk announced on Twitter that he’s assembling a legal crew to sue defamers and defend Tesla (and likely himself) against lawsuits.

But the best indication that the woke cartel has really gone berserk is its removal of Tesla from the S&P 500’s ESG (Environmental, Social, and Governance) Index. This last rebuff proves that “ESG is a scam.”

Biodiversity is on the verge of being devastated due to the inclination towards deforestation these days. The adverse climatic conditions that our Earth is facing nowadays are also the result of this pressing concern. However, to mitigate this climatic distress caused by deforestation, a team of researchers at the MIT Institute has come up with a novel technique to artificially grow wood in a controlled environment in the lab, which can then be used for making furniture and other wooden houses, which are now being made from cutting trees, thereby posing a threat to our natural habitat. Apart from the amazing growth, we can also print “3D custom-designed wooden structures” out of the replicas, which can considerably reduce wood waste as well.

Prior to discussing the mechanism of wood production, an interesting thing to note is that we can easily change the shape and structure of these artificially produced woods according to our requirements. The researchers have demonstrated the whole process through an experiment in which a flowering plant known as “Common zinnia (Zinnia Elegans)” would be taken and the cells are then extracted from its leaves which can then be conserved in a liquid mixture for several days. After it becomes nutritionally embellished, a gel-based material would be utilized to further refine the mixture.

However, these cells would then give birth to new plant cells which will then be treated accordingly as per the lab conditions. Moreover, we can also reform the physical and mechanical properties of the cells by increasing or decreasing the hormonal concentrations as per the needs.
