polympart :In the future, smart clothing might monitor our posture, communicate with smartphones and manage our body temperature. But first, scientists need to find a way to cost-effectively print intricate, flexible and durable circuits onto a variety of fabrics. Now, researchers reporting in ACS Applied Materials & Interfaces have developed a conductive 3D printing ink made of liquid metal droplets coated with alginate, a polymer derived from algae. Conventional electronics are rigid and unable to withstand the twisting and stretching motions that clothing undergoes during typical daily activities. Because of their fluid nature and excellent conductivity, gallium-based liquid metals (LMs) are promising materials for flexible electronics. However, ...

    polympart: Scientists have built a school of robot fish that are powered through the water by human heart cells. Researchers at Harvard University developed the bio-hybrid fish, which is based on a zebrafish, from plastic, paper, gelatin and two strips of living heart muscle. One strip of the muscle is on the left side of the fish’s body, and another on the right side, so when one side contracts, the other stretches, and vice-versa, causing the tail fin to create a swimming motion. “My interest is in paediatric heart disease,” Kit Parker, a Harvard bioengineer and a lead researcher of the project, told The Daily Beast. “I want to build a tissue engineered heart for a sick kid born with a malformed heart. But I can’t put ...

   polympart :Quantifying the dangers of plastic pollution in the seas and nature, a team of researchers in a new study estimates that about half of the world’s seabirds have ingested plastic additives. The researchers from Japan, the United States and other countries studied 145 seafowls of 32 species from 16 areas of the world. They found brominated flame retardants and ultraviolet absorbers--the latter being used to prevent sunlight-induced degradation of plastics--in 76 of these, including in three streaked shearwaters from Awashima island in Niigata Prefecture, which were found polluted at mild concentrations. Their findings appeared in the English-language journal of the Japan Society for Environmental Chemistry in October In addition ...

New ‘Super Jelly’ that Can Survive Being Run Over by a Car
28 نوامبر 2021

polympart: Scientists have developed a completely new soft-yet-strong, squishy materials that named Super Jelly that is capable of regain its authentic form after being run over by a automobile – or to make use of a extra pure instance, after being walked over by an elephant. Made up of 80 % water, the components of […]

Sugar could help repair artificial joint implants
25 نوامبر 2021

polympart :A sugar-containing polymer coating could one day help repair artificial joint implants, like hip replacements, when they are damaged through wear and tear, according to new research. An international team of chemists and engineers, including Durham and York universities, UK, and Tsinghua University, China, has developed the technique for easily repairing low-friction surfaces. Taking […]

Enhanced triboelectric nanogenerators of polymeric sulfur blends
24 نوامبر 2021

polympart :A triboelectric nanogenerator (TENG) is an energy-harvesting device that converts mechanical energy into electricity through contact separation or relative sliding movements of two opposite tribo-polar materials. Researchers from Inha University previously reported the first example of sulfur backbone polymer-based TENG. The surface of the sulfur copolymer film was directly fluorinated using toxic fluorine gas […]

Microplastic found in Taiwan’s high mountain Jiaming Lake
01 نوامبر 2021

  Microplastic contamination has been found in 100 percent of water samples collected from Jiaming Lake polympart: Taipei, Oct. 31 (CNA) Microplastic contamination has been found in 100 percent of water samples collected from Jiaming Lake in Taitung, the second highest mountain lake in Taiwan and a main source of drinking water for the Formosan […]

Australian beaches littered with plastic
19 اکتبر 2021

  polympart :The overwhelming amount of rubbish on Australian beaches is plastic. plastic comprises 84 per cent of all rubbish littering Australian beaches A UNSW-led study based on one of the largest marine debris databases in the Southern Hemisphere found plastic comprises 84 per cent of all rubbish littering Australian beaches. More than 2000 organisations […]

New Material That Fixes The Biggest Issue With Polymers
12 اکتبر 2021

  An example of the application of polymers in human life polympart: Polymers are ubiquitous in modern daily life. From rubber tires to plastic water bottles, from waterproof jackets to bulletproof vests, and even non-stick ware are all possible thanks to polymer science. Elastomers or elastic polymers are used in applications where the material must […]

plastic pollution and climate crisis are linked
30 سپتامبر 2021

polympart: Despite being frequently described as separate and even competing issues, the climate crisis and plastic pollution are more linked than we used to think, a new study found. Researchers called for governments and policymakers to urgently tackle the two issues together so as to avoid falling short on much-needed solutions. For the first time, […]

  polymeric material combining at the same time two properties polympart: Scientists of Tomsk Polytechnic University jointly with their colleagues from the University of Aveiro (Portugal) and a number of some overseas universities have developed a polymeric material combining at the same time two properties, which are important for further application in medical implants. ,the Biodegradable […]

Why recycling alone won’t solve the plastic crisis
28 سپتامبر 2021

  polympart: About 8 billion tons of plastic has been produced globally since the 1950s, but only 10% has actually been recycled. Recycling is increasingly seen as an unsuitable solution to the growing volume of food waste produced by the world. In addition to reducing our overall consumption levels, addressing the waste crisis will require more […]
