Recent Patents on Engineering - Volume 7, Issue 3, 2013

A state of the art search was conducted of novel applications for flexible photovoltaics (PV) in portable and niche markets. Flexible PV modules are thinner and lighter weight than traditional rigid modules, allowing them to expand into the mobile device market and areas where traditional rigid modules would be impractical. A variety of new applications are currently being developed in this technical field, with 40% of developme Read More

In the present paper we have focused on the adsorption of surfactant molecules on solid surfaces, and their further application to adsolubilization of organic molecules and heavy metal ions. The emphasis is given on the materials and surfactants used, the organics removed and the processes employed for engineering applications. The batch studies, column studies, effect of pH and other parameters are discussed briefly. Finall Read More

This work reviews the scope of the international and Brazilian inventions in the area of biopesticides. The search for patents allowed the design of a graphical evaluation of the number of patents registered each year and a description of the key patents published. An analysis of each patent allowed them to be classified into groups which resulted in a better understanding of characteristics and trends in the patenting of biope Read More

The paper overviews recent developments and research work for stiffened plates and shells in all the engineering applications. The first part reviews the analytical, numerical and modelling procedures that were developed for analysis of stiffened plates and shells. The review covers analysis of defective stiffened panels (i.e., with cracks, corrosion, material, geometric imperfections...etc). The structural idealization, th Read More

The paper presents new polyphase ceramic waste forms (matrices) of aluminosilicate-phosphate type synthesized from natural bauxites and apatite ore tailings. This ceramic material is named “geoceramics” by the authors. The optimum composition of the waste matrix is selected (Cs2O, P2O5, SiO2, and Al2O3) and a cost-saving method for synthesis of matrices capable to accommodate up to 12 wt. % of cesium and 6 wt Read More

Building sector is one of the largest primary energy consuming sectors and contributes substantial atmospheric emissions. With growth and improvement in technology, the energy consumption and comfort levels have increased exponentially. Minimizing energy consumption in all energy consuming sectors have become progressively imperative worldwide because of the many important issues, such as; increase in energy Read More
