Abstract Cyber hybrid warfare has been known since antiquity, it is not a new terminology nor a new practice. It can have an effect even more than a regular conventional war. The implementation of the cyber hybrid war aims to misinform, guide and manipulate citizens, disorganize the target state, create panic, overthrow governments, manipulate sensitive situations, intimidate groups, individuals and even shortened groups of the population, and finally to form an opinion according to the enemy’s beliefs. Creating online events designed to stimulate citizens to align with the strategy of governments or the strategy of the enemy government is a form of cyber hybrid warfare. The cyber hybrid warfare falls under the category of asymmetric threats as it is not possible to determine how, and the duration of the cyber invasion. The success or not of a cyber hybrid war depends on the organization, the electronic equipment, and the groups of actions they decide according to the means at thei...

  Abstract As populations grow, global energy consumption in the next 30 years is predicted to rise by nearly 50%. Nowadays and many years before, the most energy worldwide is provided by fossil fuel which leads to severe pollution and contributes to the greenhouse effect. Hydrogen is the most ideal alternative clean energy, but currently, there is no significant hydrogen production from renewable sources. Hence, there is an urgent need for the development of new photocatalysts which will allow a water splitting for hydrogen production. The photocatalytic water splitting using TiO 2 offers a promising approach for clean, low-cost, and environmentally friendly production of hydrogen as a sustainable fuel. This paper reviews some recently used methods of synthesis such as hydrothermal, rapid breakdown anodization method, impregnation method, and sol-gel synthesis for the preparation of modified TiO 2 materials. These methods of synthesis provide the production ...

 

Brief on Catalytic Reactions to Maximize Production and Minimize Pollution (MPMP) by SSEH Elnashaie* in Crimson Publishers: Peer Reviewed Material Science Journals   One of the main techniques for pollution control and achieving green technology is to achieve MPMP. Almost all catalytic reactions in the Petroleum refining and petrochemical industry are reversible and therefore their conversion is limited by the thermodynamic equilibrium. This conservative limitation can be broken by using selective membranes to remove one of the products. In this couple of pages editorial this revolutionary concept leading to MPMP is used for the dehydrogenation reaction where the selective membranes are used for the perm-selective removal of hydrogen [1-3]. These membranes have 100% selectivity for the removal of hydrogen. Most efficient configuration is when in the other side of the membrane is a hydrogenation reaction and the flows in the two sides of the membrane are counter-current. Such MPMP...
