Insecticide, Eatable, and Dissolvable Plastic prepared

Pollution is one of the biggest threats to life on Earth, and plastic plays a pivotal role in it. Plastic can't be destroyed. It has tremendous sustainability. It doesn't dissolve even after years; some take hundreds of thousands of years to vanish. With its ruthless use without proper disposal, it has polluted the lands and seas equally. Now, here is good news about plastic pollution.

Plastic pollution has become a problem for the whole world. In this regard, Brazilian scientists have prepared self-dissolvable, even edible, plastic. Professor Marisa Regina Demora of Sao Paulo University in Brazil has prepared a green plastic from a biological polymer, which was named bioplastic. The experts first took plastic already prepared from animals' gelatin, which is called Type B Bovine Gelatin. It is also found in colorless, odorless, and tasteless powder form, but it is less strong and elastic than petroleum plastic. Doctor Marisa mixed it in a special kind of nano clay with sodium (+Na), which increased its strength and elasticity up to 70 megapixels. Nanoemulsion drawn from black pepper was also amalgamated in it. This added taste and odor and increased its storage period. The expert also became aware of its anti-oxidant and anti-microbial characteristics at the end. 

The experts hope that this less expensive and environmentally friendly plastic can be used in plastic bags and packing. It can be more effective than the common plastic and can help eliminate plastic pollution, which is the need of the hour.

The smallest battery in the world equals a salt particle

The experts have made a succinct robot and microscopic sensors of the world, but electrifying them is still the biggest problem. The scientists from the University of GameNuts in Germany have prepared the smallest battery in the world to electrify such sensors. It looks like a salt particle. According to them, it was made in inspiration from Swiss Roll. It comes into being under the rule of self-assembly.

First of all, it can be used in the microbots and sensors present in the body, but giving them electricity is a problem. The experts have made electricity-storing electrodes in the form of roll platters in which polymeric, metallic, and dielectric materials have been used. All these have been installed on a wafer, and this microscopic battery looks like baleen.

This battery can produce 100 microvolts of electricity per square centimeter. It produces electrical layers due to internal pressure. According to scientists, it can provide electricity to many wafer-thin circuits because of its microfabrication.

These devices in the body can measure the blood flow, oxygen level, and quantity of glucose, due to which human lives can be saved. It can also be used in robotic systems and extremely elastic electricals.

Intro of Hybrid and Rechargeable Train

Japan has introduced a train of Fuel cells (cells that convert chemical energy into electricity) and rechargeable batteries which has been named "Hybrid Train". It was made by J.R. East company with the collaboration of other corporations. It has been decided to launch this Hybride Technology by 2030. Untill then the company will carry out different tests of the train. The company is determined to achieve zero carbon emissions with the help of using Hybrid Technology in trains until 2050. 

Hybrid Technology is an environment-friendly technology as it can play a vital role in the reduction of carbon emissions, which improves the vehicle system to use electric and gas power combined while driving. It reduces fuel consumption to save money and causes less harm to the environment, depending on the mode.
