Initial dynamic thermal dissipation modes enhance heat dissipation in gold nanoparticle–polydimethylsiloxane thin films

T.V. Howard, K.R. Berry, D.K. Roper. Published in the Journal of Thermal Analysis and Calorimetry

Thermal ablation of cancer tumors using irradiated nanoparticles is one way plasmonic nanoparticles are useful to engineer biology. This article shows hot irradiated plasmonic nanoparticles dissipate energy superlogarithmically, surpassing typical convective and conductive heating. This superheating is optically localized by dielectric properties of surrounding medium.

Augmentation of Granular Anaerobic Sludge with
Algalytic Bacteria Enhances Methane Production from Microalgal Biomass

This study describes an approach to improve conversion of a waste microalgal biomass into a useful resource, biogas. Novel bacteria, isolated from Logan Wastewater Treatment Lagoons, were used to augment anaerobic digestion of microalgal biomass and led to a significant increase in production of biogas. The demonstrated experimental approach is of value to all the areas of biological waste treatment and can be applied to enhance energy recovery with a sustainable resource use.

Activity of Preserved Anaerobic Sludge.

This research investigated how prolonged storage at different temperatures affects activity of anaerobic sludge. Active anaerobic sludge harbors microorganisms that can convert organic waste into biogas, and when bioreactors are shut down for maintenance, microbial activity can be lost. This study compares different methods of sludge storage and concludes that microbial activity is still significant after 6 months of storage. These results have a direct value to all the anaerobic digestion industries that need to store their active microbial consortia.
