Eco and Eco trend in life

WHAT IS ECO?

Today, the world is facing heavy pollution due to the destruction of ecosystems over a long period of time due to waste discharge and unplanned exploitation. Eco has become a trend of enthusiastic support from the community thanks to the many benefits it brings: limiting waste which adversely affects the environment, balancing the ecosystem, preventing many natural disasters and harassment. yards ... So what is Eco?

Eco is an abbreviated state of the word ecology. Ecology means ecology is the science that studies the distribution and life of living organisms and the interactions between organisms and their habitats. So, all activities in the fields of curving life in particular are operated according to the above rules ie expressing eco style. Eco style (translated as ecological trend) appeared in the early years of the 20th century, calling for a lifestyle that shows a high sense of responsibility to the environment, limiting bad impacts on the environment to protect the system. Global ecological sustainability.

APPLICATION OF ECO MATERIALS TO LIFE

Many countries in the world started to have many research projects and application of eco-materials (raw materials originating from nature) into the production process to gradually replace industrial materials that in the process of declaration Falls lose the balance of the ecosystem.

Leading today in countries adopting ecological trends into everyday life can be mentioned in France. According to the Associated Press, France is the first country to ban all plastic cups and plates in a law that will be in full force in 2020. Measures were passed last month, but businesses have time to come. 2020 to fully implement.

All disposable plates in France will instead have to be made of biologically sourced materials. Since July, France has banned the use of all types of plastic bags, some countries have made this move, but France is the first country to expand sanctions to all kinds of dishes.

In Thailand, a team of Naresuan University created and developed a dish from leaves. They are biodegradable and waterproof. The professors of the university have spent more than a year studying and producing these dishes, which are absolutely useful to be able to replace the styrofoam foam-filled food containers. Through a process of research, 3 types of bastard teak, teak and banyan plants were chosen as the best materials to make dishes, they could hold hot water without leaking to the outside and would completely disintegrate. after use. The researchers used starch to make the dish more shiny and beautiful.

Professor Samorn Hiranpraditsakul said the idea for the project came after she visited a temple in northern Thailand, she witnessed the "horrific" scene of porous dishes with the risk of being polluted. mountain.

During a study of a leather material replacement solution in the Philippines, Carmen Hijosa - a Spanish leather designer, discovered the use of pineapple leaves, thanks to her traditional Barong Tagalog outfit. Mr. Philippines. She collaborated with local weavers to test and eventually created Pinatex faux leather, made from cellulose fibers from pineapple leaves.

Producing fake leather from pineapple leaves

This material is both durable, cheap, beautiful and environmentally friendly, promising to become a sustainable material to replace materials such as polyurethane and PVC fibers for the garment industry, limiting dynamic abuse. Things of the fashion industry. Currently, Pinatex yarns are used by some famous fashion brands such as Puma or Camper to successfully produce many highly aesthetic "vegetable skins" similar to products from real leather. Dr. Carmen is still in the process of considering the direction of development of Pinatex fibers for wider application in other areas such as making anti-bacterial medical bandages and building insulation materials.

Meanwhile, recently in Vietnam, 2 grade 11 students specializing in Gia Dinh, Le Duy Khang and Nguyen Hoang Dung high schools have inherited many researches on producing plastic from potato starch and bringing it into application. Successful production of potato starch plastic bags. This bio-plastic bag product is much less biodegradable than the products made from industrial materials, contributing to protecting the environment greener, more beautiful and raising community awareness about environmental Protection.

calculate pH of phosphoric acid

Question: adding 1/4 teaspoon of 10% phosphoric acid  to 19 litres of water, what will be the pH? Let's go through the calculations step by step. Step 1. Convert mass ( or volume) of 10% phosphoric acid to mole per litre ( mol/L) The above calculation shows that 1/4 tsp of H3PO4 acid is 6.97e-5 mol/L Step 2. Input this value to BATE (or other app) to calculate pH The answer: pH = 4.16, ie too acidic !? If you use pipette instead of teaspoon,  1 drop = 0.05ml. So 1/4 TSP means roughly 25 drops If you actually aim for pH 5.6 (which is optimum pH for mashing), conc will be 2.51 e-6, or 1/100 tsp , 0.044 ml, roughly 1 drop Let's roll back a bit. From  recipes of   BarleyWine , summer rye , hefe Gordon Strong suggested to use 1/4 teaspoon of 10% phosphoric acid, which is targeting pH of 5.5..... Discussion on  homebrewtalk  forum. However using online BF water calc , Sparge pH would be 4.6. but he also added 1 tsp of CaCl2. 2H20. Mash pH change from 5.7 t...
