The present work was carried out in order to evaluate the world's scientific production with respect to the topic of biomass, based on articles published from 2007 onwards. The data were obtained from the Web of Science data collection, and analyzed, through the HitsCite metadata processor, within which indicators were highlighted, such as the number of total publications, the countries that publish the most, in different periods of years, to establish the trend graphically and in the future, to be able to predict the behavior that will occur. The results show that of the 874 articles published to date, 168 were published by the United States, which is equivalent to 19.2%, followed by China, Italy and finally the United Kingdom with 65 articles published (7.4%), 64 articles (7.3%) and 56 articles published (6.4%) respectively. In addition, a PEST analysis was developed to analyses the behavior of the number of publications in relation to the political, economic, social and technological fields for each country studied, in order to be able to create means of prediction in the future.

In order to improve the learning process about the unit operation of Liquid Extraction, it is presented a GUI in Matlab® for designing extracting systems with different types of contact, where the stages reach the equilibrium between both liquid phases. The program called ExtractING is an application of theoretical studies and material balances presented in highly relevant documents and popular academic books, which has a general procedure that initiates by introducing feed and solvent quantities with their respective compositions, and a raffinate exit condition for multistage equipment. It is necessary to introduce the ternary system (solute, dissolvent, diluent) and an operating temperature to calculate equilibrium conditions with Van Laar activity model equations. Material balances, multiple iterative routines, and equilibrium diagrams were used to calculate raffinate and extract conditions in all the stages as well as the minimum number of stages needed for the required separation allowing the user to get the approximate size and cost of the equipment, making this software a powerful academic tool. With the program, it was compared the maximum separation for specified conditions between counter-current and crosscurrent equipment, the separation percentage behavior with an increasing feed quantity, and the separation behavior with variations of temperature.

With the aim to enhance the learning process of the unit operation of Leaching, it is presented a GUI in Matlab® for designing systems with different types of contact where the stages reach the equilibrium between the solid and liquid phase. The program called LeachING is an application of theoretical studies and material balances presented in highly relevant documents and popular academic books, which has a general procedure that initiates by introducing the feed and solvent quantities with their respective compositions, and a raffinate exit condition for multistage equipment. Finally, material balances and multiple iterative routines were used to calculate raffinate and extract exit conditions, and the minimum number of stages necessary to reach them, allowing the user to get the approximate size and cost of the equipment making this software a powerful academic tool. With the program, it was compared the maximum separation for given conditions between countercurrent and crosscurrent equipment, the behavior of the percentage of separation when increasing feeding with constant solvent, and the behavior of the maximum feeding for the different types of contact.

Currently, CO2 capture and storage is a method approved by many countries to combat CO2 emissions, taking power and oil plants as study areas. According to many climate agreements made in the last decade, developed countries have implemented capture and storage projects in several countries, resulting in a reduction of CO2 emissions and being a key player in reducing global temperatures by 2050 using protocols, research centres and government support for future capture projects. The study conducted research on the countries with the largest number of publications on CO2 capture, considering the actions taken by different governments on issues related to politics, economics, society and technology with the help of a PEST analysis.
