Russian president demanded that exports of Russian gas to "unfriendly" countries be settled in rubles. The demand has raised concerns in Germany about possible supply disruptions and the impact on industry and households if utilities do not pay in robles. Europe gets about 40% of its gas from Russia. Last year, Europe imported about 155 billion cubic meters. Germany, Europe's largest economy, depends heavily on Russian gas.
The chief executive of Germany's E.ON said the German economy would face "significant damage, which should be avoided if possible" without Russian supplies. He also said it would take Germany three years to wean itself off Russian gas.
In the event of a supply disruption, Germany's gas network regulator would prioritize home heating over industrial use, so energy-hungry manufacturers such as steelmakers would be the first to suffer, he said.
The volatile international situations will continue to affect the markets and prices of many commodities like the Cellular Concrete Foaming Agents.
Introduction to Cellular Concrete:
Cellular concrete or cellular lightweight concrete (clc) consists of cement, water, and preformed foam. Foam allows a relatively high proportion of stable air voids to mix into the mixture, and thus a cellular or porous solid can be produced after curing of the mixture. The air content in cellular concrete is between 10% and 70%. When cellular concrete hardens, it can reach an oven-dry density of 50 lb/ft3 (8 t/m3).
Production Process of Cellular Concrete:
The production process is divided into two steps. In the first stage, a foam generator is used to make microscopic stable foam: solution of the foaming agent is fed into the foam generator to generate a dense foam. In the second stage, the foam is mixed with a cement slurry. Normally, the dry density of such mixture is between 250 and 1600 kilograms per cubic meter. When the cellular lightweight concrete is used for insulation or filling purposes, the density is between 400 and 800 kilograms per cubic meter.
Applications of Cellular Concrete:
Flat top heat shield;
Fire prevention of wood flooring and steel structure works;
Fabrication of light beams, blocks and panels;
Fill old underground pipes, abandoned tunnels, sewers, cisterns, shelters and basements, repair ditches;
The properties of the cellular concrete, like the thermal resistance and sorptivity coefficient, are strongly influenced by the type of foaming agent used. Currently, there are two types of foaming agents available, protein based foaming agents and synthetic foaming agent.

Researchers at the Centre for Translational Atomic Materials at Swinburne University of Technology, Melbourne, Australia have developed a new graphene film that absorbs more than 90% of sunlight while eliminating most of the infrared thermal emission losses, a highly efficient A solar-heated metamaterial capable of rapidly heating to 83 degrees Celsius (181 degrees Fahrenheit) in an open environment with minimal heat loss. Proposed applications for the film include thermal energy harvesting and storage, solar thermal power generation, and seawater desalination.
