Biodegradable polymers from whey

Serafim L.S., Lemos P.C., Prieto M.A., Reis M.A.M., FCT/UNL, PT

The replacement of synthetic plastics by biodegradable polymers such as polyhydroxyalkanoates (PHA) is urgent. The final price of these polyesters is higher and the production costs should be decreased. Whey, which is the major by-product [...]

Low-Energy, Solventless Coating Processes

Lewis H.P., GVD Corporation, US

GVD Corporation is commercializing solvent-free, chemically-pure polymer coatings formed by chemical vapor deposition (CVD). GVD’s all-dry coatings currently range from fluorocarbons to silicones to electrically-conductive polymers. These novel coatings are deposited from the vapor phase, [...]

Clean Hydrogen Peroxide Synthesis via a Nanocatalyst Process

Zhou B., Headwaters Technology Innovation, US

A nanotechnology platform developed at Headwaters Technology Innovation (HTI) has many applications. A case study based on synthesis of hydrogen peroxide (H2O2) from hydrogen and oxygen will be used as an example and discussed. H2O2 [...]

Micropatterning Layers by Flame Aerosol Deposition – Annealing

Tricoli A., Graf M., Mayer F., Kühne S., Hierlemann A., Pratsinis S.E., PTL, CH

The development of scalable methods, which effectively bind nanoparticles to surfaces and provide precise patterns, is a key step towards the commercial exploitation of the distinctive properties of nanoparticles. In this context, the direct deposition [...]

Deposition and Characterization of Platinum Nanoparticles on Highly Orientated Pyrolytic Graphite

Elizondo-Villarreal N., Novar C., Zhou J.P., Alvarez Contreras L., Tel Vered R., Universidad Autonoma de Nuevo Leon, MX

Platinum is considered one of the best electrocatalyst for low temperature reactions in a H2/O2 fuel cell. Metallic nanoparticles are of great interest because of the modification of properties observed due to size effects, modifying [...]

Production of Renewable Solar Hydrogen using Semiconductor Metal oxides by Water Photoelectrolysis

Misra M., Mohapatra S.K., Mahajan V.K., Das P.P., Raja K.S., University of Nevada Reno, US

Semiconductor metal oxide catalysts are exploited as photoelectro catalyst to generate hydrogen by water photoelectrolysis. A special design is carried to to get high volume of hydrogen for longer time.

Renewable Hydrogen Production Around the Globe

Deason K., Smith A., SENTECH, Inc., US

Survey of demonstration projects involving renewably produced hydrogen around the world.

Domestic hydrogen production by an integrated biomass gasification/sponge iron process

Gerdes T., Willert-Porada M., University of Bayreuth, DE

The share of hydrogen in the energy market is increasing with the implementation of fuel cell systems and the growing demand for zero-emission fuels. One major challenge is a distribution system for hydrogen. This drawback [...]

An Assessment of Renewable Hydrogen Costs, Infrastucture, and Resource Constraints

Lasher S., Marion M., Kromer M., Roth K., TIAX LLC, US

This study uses a hydrogen logistics model to determine the most economic renewable resources and infrastructure to supply hydrogen to demand centers across the U.S. The model minimizes the projected average price for renewable-hydrogen using [...]

Protective Sensor Coatings for High-Throughput Screening of Hydrogen-Producing Microbes

Pryce Lewis H., GVD Corporation, US

Microbe-based hydrogen production is a potentially cost-effective, non-polluting approach to the production of hydrogen. Research efforts are underway to identify, isolate, and enhance microbial strains which facilitate direct sunlight-to-hydrogen conversion. These efforts are hampered by [...]
