چکیده
Biogas and biohydrogen, due to their renewable nature zero carbon footprint, are considered two of the gaseous biofuels that will replace conventional fossil fuels. from anaerobic digestion must be purified converted into high-quality biomethane prior use as a vehicle fuel or injection natural gas networks. Likewise, enrichment biohydrogen dark fermentation requires removal CO2, which is main pollutant this new biofuel. Currently, CO2 both biogas carried out by means physical/chemical technologies, exhibit high operating costs corrosion problems. Biological technologies for biogas, such photosynthetic hydrogenotrophic enrichment, still in an experimental development phase. In context, membrane separation has emerged only technology with potential improve performance reduce investment costs, result recent advances field nanotechnology materials science. This review focus on fundamentals, limitations H2 technologies. The latest purification systematically reviewed.

Recent Advances in Hemophilia Gene Therapy
Heterogeneous loss of function mutations at F8 and F9 genes causes X-linked recessive bleeding disorders, hemophilia A (HA) and hemophilia B (HB), respectively. HA is clinically indistinguishable from HB and accounts for more than 80% of hemophilia cases; the former affects 1/5000 and the latter 1/25000 male births worldwide. In Iran, it is estimated that around 4300 HA and 900 HB patients are ...
متن کاملSelected Methods of Advanced Biogas Upgrading
The upgrading of biogas for the production of biomethane to be injected to the natural gas grid has gained significant importance in recent years. It is often considered to be superior to the production of electricity and district heat with internal combustion engines mainly because of better energy utilisation, higher flexibility and beneficial economic prospects. Biogas upgrading is commonly ...
متن کاملRecent Advances in Pd-Based Membranes for Membrane Reactors.
Palladium-based membranes for hydrogen separation have been studied by several research groups during the last 40 years. Much effort has been dedicated to improving the hydrogen flux of these membranes employing different alloys, supports, deposition/production techniques, etc. High flux and cheap membranes, yet stable at different operating conditions are required for their exploitation at ind...
