A bioanode for glucose based biofuel cell have been fabricated by combining glucose oxidase and highly ordered Palladium (Pd) nanowire array electrode. The Pd nanowires were 5.57 μm in length and 64.28 nm in diameter. The hydrogel composite modified Pd nanowire array bioanodes were characterized with cyclic voltammetry in the presence of different scan rates and different substrate concentratio...

Chlamydomonas reinhardtii is widely used to study many biological processes including biofuel production. Here, we present a rapid transformation technique for cell-walled Chlamydomonas strains without cell-wall removal using a square electric pulses-generating electroporator. This method could be applied to transformation of other industrially useful algae by optimizing the electric conditions.

In this study, the opportunity to invest in combined heat and power (CHP) plants and second-generation biofuel production plants in Europe is investigated. To determine the number and type of production plants, a mixed integer linear model is used, based on minimization of the total cost of the whole supply chain. Different policy scenarios are studied with varying values of carbon cost and bio...

Despite a rapid worldwide expansion of the biofuel industry, there is a lack of consensus within the scientific community about the potential of biofuels to reduce reliance on petroleum and decrease greenhouse gas (GHG) emissions. Although life cycle assessment provides a means to quantify these potential benefits and environmental impacts, existing methods limit direct comparison within and be...

In recent years the popularity of biofuels has been transformed from a sustainable option for transportation to a questionable and criticized method. Many reports have therefore been produced to view biofuel production from a life cycle perspective; though results may be misleading. In a number of the reports, biofuel production is viewed in a linear manner, i.e. crops and energy in and biofuel...

The productive cellulosic crops switchgrass and Miscanthus are considered as viable biofuel sources. To meet the 2022 national biofuel target mandate, actions must be taken, e.g., maize cultivation must be intensified and expanded, and other biofuel crops (switchgrass and Miscanthus) must be cultivated. This raises questions on the use efficiencies of land and water; to date, the demand on thes...

Single-walled carbon nanohorns (SWNHs), a new type of carbon nanomaterials, possess excellent catalytic properties, high-purity, and low toxicities, which make them suitable for bioelectrochemical application. Here a biofuel cell anode has been developed by using SWNHs as the support for redox mediator and biocatalyst for the first time. Cyclic voltammetric results show SWNHs promotes the elect...

Biofuel cells are devices that convert biochemical energy directly into electrical energy. They are distinguished from conventional fuel cells by the use of biocatalysts (enzymes/microbes) to generate electricity from organic substrates such as carbohydrates. Microfluidic biofuel cells exploit the difficulty of mixing at low Reynolds number to eliminate the use of membranes, which are commonly ...
