Biobutanol production from agricultural residue.
This document summarizes biobutanol production from agricultural residues. It discusses how butanol can be used as a biofuel with properties similar to gasoline. Biobutanol is produced through fermentation of carbohydrates from renewable resources by Clostridium bacteria. Using agricultural residues as substrates can reduce biobutanol production costs. Pretreatment is required to hydrolyze the cellulose in residues to fermentable sugars. Key factors in fermentation include operating pH, nutrients, and the use of continuous bioreactors coupled with product removal systems to improve yields.
Biofuels
The document discusses first generation biofuels. First generation biofuels are derived from sources like starch, sugar, vegetable oils, and animal fats using conventional techniques. Some examples given are ethanol, biodiesel from vegetable oils, and biogas. While they provided early alternatives to fossil fuels, first generation biofuels face sustainability challenges as they compete with food production and may not provide significant environmental benefits over fossil fuels. Future research focuses on second and third generation biofuels from non-food sources like lignocellulosic biomass and algae.
Bioethanol
This document provides an overview of bioethanol, including its production process, feedstocks, fuel properties, advantages, and disadvantages. Bioethanol is produced through sugar fermentation of plants containing sugars and starch, such as corn, sugarcane, or wheat. It is used as a substitute for gasoline in vehicles. While bioethanol production reduces greenhouse gas emissions and reliance on oil, it also requires large amounts of land and water and has lower energy content than gasoline. Brazil is highlighted as the largest producer and user of bioethanol due to its sugarcane crops and government policies supporting ethanol production.

Biofuel-Powerpoint-main
This document discusses different types of biofuels and whether they are an environmental solution or problem. It outlines three main types of biofuels: first generation from starch/sugar/vegetable oil which are not sustainable; second generation from non-food crops; and third generation from algae. While biofuels can be used as fuel substitutes and help reduce global warming, first generation biofuels could damage food supplies if used in large quantities. The document also notes biofuels' advantages like being renewable and sourced from waste, but disadvantages include high costs and overuse of fertilizers in crop production.

Biofuels are liquid fuels produced from biomass rather than fossil fuels. The two main types are bioethanol, produced from crops high in sugar or starch through fermentation, and biodiesel, produced from vegetable oils or animal fats. Biofuels provide environmental benefits like reducing greenhouse gas emissions and decreasing dependence on foreign oil. While biofuels have advantages, their production also has potential drawbacks like requiring significant land and water resources as well as possibly introducing invasive species.
Bioethanol
Bagasse, a waste product of sugarcane processing, can be used to produce bioethanol through fermentation. Bagasse contains cellulose that can be broken down through pretreatment and hydrolysis into glucose, then fermented by bacteria like Clostridium thermocellum into bioethanol. Producing bioethanol from bagasse provides an environmentally friendly alternative fuel and makes use of an agricultural waste product.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
