1. Proton-Conducting Sulfonated Aromatic Ionomers and Membranes by Chemical Modifications and Polycondensations
Abstract : Proton-exchange membrane fuel cells (PEMFC)s are increasingly regarded as promising environmentally benign power sources. Intensive development is today directed towards reducing the cost and increasing the durability of the fuel cell, as well as expanding the operational window for the PEMFC for a range of applications.

2. Durable Polysulfones with Densely Sulfonated Segments for Highly Proton Conducting Membranes
Abstract : Fuel cells are considered as a promising alternative environmentally benign power source to the existing ones depending on petroleum oil. Especially, proton-exchange membrane fuel cells (PEMFCs) have been intensively developed during the last decade because of their wide application windows including various portable, stationary and transportation applications.

3. Development of ring-opening catalysts for diesel quality improvement
Abstract : The global oil refining industry with its present shift inproduct distribution towards fuels such as gasoline and dieselwill most likely hold the fort for many years to come. However,times will change and survival will very much depend onprocessing flexibility and being at the frontiers of refiningtechnology, a technology where catalysts play leading roles. READ MORE

5. The relationship between fly ash chemistry and the thermal formation of polychlorinated pollutants during waste incineration
Abstract : The thermal formation of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), biphenyls (PCBs), and naphthalenes (PCNs) is a major problem in waste incineration. Ideally, rather than relying on air cleaning systems and treatment techniques, their formation should be minimized or, if possible eliminated. READ MORE
