Environmental Impact of Graphene's Adoption into Everyday Life

Description
Graphene has the ability to advance many common fields, including: membranes, composites and coatings, energy, and electronics. For membranes, graphene will be used as a filter for desalination plants which will reduce the cost of desalination and greatly increase water security in developing countries. For composites and coatings, graphene's strength,…

Graphene has the ability to advance many common fields, including: membranes, composites and coatings, energy, and electronics. For membranes, graphene will be used as a filter for desalination plants which will reduce the cost of desalination and greatly increase water security in developing countries. For composites and coatings, graphene's strength, flexibility, and lightweight will be instrumental in producing the next generation of athletic wear and sports equipment. Graphene's use in energy comes from its theorized ability to charge a phone battery in seconds or an electric car in minutes. Finally, for electronics, graphene will be used to create faster transistors, flexible electronics, and fully integrated wearable technology.

Accounting for Uncertainty and Variation in Accessibility Metrics for Public Transport Sketch Planning

Description

Accessibility is increasingly used as a metric when evaluating changes to public transport systems. Transit travel times contain variation depending on when one departs relative to when a transit vehicle arrives, and how well transfers are coordinated given a particular timetable. In addition, there is necessarily uncertainty in the value…

Accessibility is increasingly used as a metric when evaluating changes to public transport systems. Transit travel times contain variation depending on when one departs relative to when a transit vehicle arrives, and how well transfers are coordinated given a particular timetable. In addition, there is necessarily uncertainty in the value of the accessibility metric during sketch planning processes, due to scenarios which are underspecified because detailed schedule information is not yet available. This article presents a method to extend the concept of "reliable" accessibility to transit to address the first issue, and create confidence intervals and hypothesis tests to address the second.

Optimization of a Modified TiO2 Photocatalyst to Improve Converstion of CO2 into Methane with a Short Essay on the Economic and Environmental Impact of NextPotential's X-Doped Photocatalyst

Description
The financial feasibility of NextPotential's X-doped photocatalyst is uncertain, the outcome depends on how much the material cost becomes reduced due to mass production techniques. If carbon taxes continue on the current trend the photocatalyst is highly likely to become financially feasible. Without carbon taxes, it is still likely the…

The financial feasibility of NextPotential's X-doped photocatalyst is uncertain, the outcome depends on how much the material cost becomes reduced due to mass production techniques. If carbon taxes continue on the current trend the photocatalyst is highly likely to become financially feasible. Without carbon taxes, it is still likely the photocatalyst will achieve economical feasibility. The land area required by the photocatalyst is a feasible size. The minimal environmental downsides are that more land will be used and water will be used, but both of these are minimal compared to the benefit of eliminating carbon emissions.
