Sunlight-mediated inactivation of health-relevant microorganisms in water: a review of mechanisms and modeling approaches. [PDF]

open access: yes, 2018
Health-relevant microorganisms present in natural surface waters and engineered treatment systems that are exposed to sunlight can be inactivated by a complex set of interacting mechanisms.

Using the Microsoft Excel ‘Solver’ Tool to Perform Non-Linear Curve Fitting, Using a Range of Non-Newtonian Flow Curves as Examples.

open access: yesApplied Rheology, 2001
The Microsoft Excel ‘Solver’ tool is a very simple but powerful procedure, even in the hands of the mathematically disadvantaged. It has very good application for quickly fitting experimental flow-curve data to non-Newtonian flow models with any number ...

Algae Living in Salamanders, Friend or Foe? [PDF]

open access: yes, 2018
Roughly speaking, our bodies use energy from the sun, but we can\u27t use sunlight directly. Instead, plants and algae collect sunlight and store it as chemical energy through the process of photosynthesis.

Challenges and opportunities in continuous flow processes for electrochemically mediated carbon capture

open access: yesiScience, 2022
Summary: Carbon capture from both stationary emitters and dilute sources is critically needed to mitigate climate change. Carbon dioxide separation methods driven by electrochemical stimuli show promise to sidestep the high-energy penalty and fossil-fuel

Solar Sails : Technology and demonstration status [PDF]

open access: yes, 2012
Solar Sail propulsion has been validated in space (IKAROS, 2012) and soon several more solar-sail propelled spacecraft will be flown. Using sunlight for spacecraft propulsion is not a new idea.

A Brief History of the Yield Stress

open access: yesApplied Rheology, 1999
This short article is a summary of a recently published, lengthy review [1] in which the author challenges the often-accepted view that materials have yield stresses, below which no flow takes place.

Plasmonic Nanostructure Design for Efficient Light Coupling into Solar Cells [PDF]

open access: yes, 2008
We demonstrate that subwavelength scatterers can couple sunlight into guided modes in thin film Si and GaAs plasmonic solar cells whose back interface is coated with a corrugated metal film.

An examination of the use of rotational viscometers for the quality control of non-Newtonian liquid products in factories

open access: yesApplied Rheology, 2001
A frequent task undertaken by quality-control personnel in typical consumer-goods factories is the measurement of the viscosity of liquid products. The problem often faced in this task is how to strike the correct balance between the complete rheological

The impact of the Kasatochi eruption on the Moon's illumination during the August 2008 lunar eclipse

open access: yes, 2011
The Moon's changeable aspect during a lunar eclipse is largely attributable to variations in the refracted unscattered sunlight absorbed by the terrestrial atmosphere that occur as the satellite crosses the Earth's shadow.
