Simulation and Analysis of Biogas operated Double Effect GAX Absorption Refrigeration System

A thermodynamic simulation of a double effect generator heat exchanger absorption refrigeration cycle using biogas as source of energy has been carried out. The binary mixture considered in the present investigation was NH3 – H2O (Ammonia - Water). This simulation was performed in order to investigate the effect of the temperature and pressure of the high temperature generator and the pressure of evaporator have over the Coefficient of Performance (COP) for a constant condenser and absorber temperatures. The basic parameters at various state points of the cycle was computed using standard correlations. The solution circulation rates and volume of biogas required for operation of the cycle are analysed for the variations in operating parameters at the high temperature generator and evaporator

Bimetallic Pd–Au/TiO2 Nanoparticles: An Efficient and Sustainable Heterogeneous Catalyst for Rapid Catalytic Hydrogen Transfer Reduction of Nitroarenes

Anilines are one of the important chemical feedstocks and are utilized for the preparation of a variety of pharmaceuticals, agrochemicals, pigments, and dyes. In this context, the catalytic reduction of nitro functionality is an industrially vital process for the synthesis of aniline derivatives. Herein, we report an efficient nanosized bimetallic Pd–Au/TiO2 nanomaterial which is proved to be quite efficient for rapid catalytic hydrogen transfer reduction of nitroarenes into corresponding amines. Significantly, the reduction process is successful under solvent-free and mild green atmospheric conditions. Bimetallic Pd–Au nanoparticles served as the active center, and TiO2 played as a support in hydrogen transfer from the source hydrazine monohydrate. Typical results highlighted that the reactions were very rapid and the products were obtained in good to excellent yields. Significantly, the process was successful in the presence of a very low amount catalyst (0.1 mol %). Furthermore, the reaction showed good chemoselectivity and compatiblity with double or triple bond, aldehyde, ketone, and ester functionalities on the aromatic ring. Typical results indicated the true heterogeneous nature of the Pd–Au/TiO2 nanocatalyst, where the catalyst retained the activity, without loss of its activity

Article 09415

ABSTRACT INTRODUCTION Today's there square measure a growing range of moveable applications requiring small-area low-power highoutturn electronic equipment. Therefore, circuits with low power utilization grow to be the foremost vital candidates for style of microprocessors and system mechanism. The battery technology doesn't advance at constant rate because the electronics technology and there's a imperfect amount of power on the market for the mobile systems. The goal of extending the battery lifetime of moveable natural philosophy is to cut back the energy consumed per mathematical process, however low power consumption doesn't primarily imply low energy. To execute associate mathematical process, a circuit will acquire through low power by continuance at terribly low frequency however it's going to take a really lasting to complete the operation. Adder is a standout amongest the most fundamental segments of a CPU ( Central processing unit), Arithmetic logic unit (ALU), and coasting point unit and location era like store or memory access unit. Then again, expanding interest for versatile supplies Such as phones, personal digital assistant (PDA), and Notebook PC, emerge the need of utilizing zone and Power proficient VLSI circuits. Conventional adder is one in all the chief essential components of a processor that decides its out turn, and for address era just if there should be an occurrence of reserve or operation the complete adder execution would have an impact on the system as a whole. a spread of full adders. Abuse static or dynamic logic gates are accounted within the literature. In this paper, have a tendency to propose a logical methodology to style 10-transistor full adders and 28t full adders. Our new adders even have the limit misfortune issue; in any case, the adders square measure supportive in bigger circuits like multipliers regardless of the edge misfortune disadvantage. a substitution full adder known as static energy recovery full adder utilizes exclusively 10 transistors that has the most modest sum scope of transistors and has reduces the power dissipation, for every Power decline is one in all the first issues in today's VLSI style techniques as a consequence of a few reasons one is that the long battery in operation life interest of movable gadgets and second is owing to expanding scope of transistors on one chip brings about high power dissipation. The power consumption for CMOS circuits is described by the following equation: P avg = P dynamic + P short circuit + P leak Pavg =fclkCLαiV 2 dd + fclkI short V dd + I leak V dd Clearly see that the power depends on different parameters as well as on supply voltage (Vdd). Lowering Vdd would significantly reduce the power consumption of the circuit. This basic concept would be utilized to improve the power performance of the adder in this paper
