Enzyme catalysed biofuel cells

Abstract: Biofuel cells are energy conversion devices that use biocatalysts to convert chemical energy to electrical energy. Over the last decade, research in this area has intensified, especially in the area of direct electron transfer between enzymes and electrodes. This review details the fundamentals of enzymatic biofuel cells and reviews characterization techniques that can be used to evaluate and optimize biofuel cells. The review details the advantages and disadvantages of mediated and direct bioelectrocatalysis at electrodes for biofuel cells. It also compares and contrasts different enzyme immobilization techniques and different electrode structures.

Current understanding of tropical cyclone structure and intensity changes – a review

Abstract: Current understanding of tropical cyclone (TC) structure and intensity changes has been reviewed in this article. Recent studies in this area tend to focus on two issues: (1) what factors determine the maximum potential intensity (MPI) that a TC can achieve given the thermodynamic state of the atmosphere and the ocean? and (2) what factors prevent the TCs from reaching their MPIs? Although the MPI theories appear mature, recent studies of the so-called superintensity pose a potential challenge. It is notable that the maximum intensities reached by real TCs in all ocean basins are generally lower than those inferred from the theoretical MPI, indicating that internal dynamics and external forcing from environmental flow prohibit the TC intensification most and limit the TC intensity. It remains to be seen whether such factors can be included in improved MPI approaches.

Patriarchy, Crime, and Justice: Feminist Criminology in an Era of Backlash

Abstract: Feminist criminology, as an outgrowth of the second wave of feminism, came of age during a period of considerable change and political optimism. As a mature field, it now inhabits a social and political landscape radically altered and increasingly characterized by the politics of backlash. Given feminist criminology’s dual focus on gender and crime, it is uniquely positioned to respond to two core aspects of the current backlash political agenda: racism and sexism. To do this effectively, feminist criminology must prioritize research on the race/gender/punishment nexus. This article provides three examples of how such a focus exposes the crucial roles played by constructions of the crime problem as well as current crime-control strategies in the ratification and enforcement of antifeminist and racist agendas. Finally, the field must seek creative ways to blend scholarship with activism while simultaneously providing support and encouragement to emerging feminist criminologists willing to take such risks.

Use of macroalgae for marine biomass production and CO2 remediation: a review

Abstract: Biomass production from macroalgae has been viewed as important mainly because of the need for pollution abatement. Environmental considerations will increasingly determine product and process acceptability and drive the next generation of economic opportunity. Some countries, including Japan, are actively promoting "green" technologies that will be in demand worldwide in the coming decades. Should an international agreement on CO2-reduction be ratified, its effective use for energy production would be of high priority. This report shows that macroalgae have great potential for biomass production and CO2 bioremediation. Macroalgae have high productivity, as great or greater than the most productive land plants, and do not compete with terrestrial crops for farm land. The review focuses on recent data on productivity, photosynthesis, nutrient dynamics, optimization and economics. Biomass from macroalgae promises to provide environmentally and economically feasible alternatives to fossil fuels. Nevertheless, the techniques and technologies for growing macroalgae on a large-scale and for converting feedstocks to energy carriers must be more fully developed.
