Electronic Effect Of Platinum Alloy Catalysts On Olefin Hydrogenation Kinetics, Colin Reedy, Jeff Miller, Stephen Purdy Aug 2018

#### Electronic Effect Of Platinum Alloy Catalysts On Olefin Hydrogenation Kinetics, Colin Reedy, Jeff Miller, Stephen Purdy

##### The Summer Undergraduate Research Fellowship (SURF) Symposium

Dehydrogenation of alkanes is the first step in transforming light hydrocarbons into liquid fuels and chemicals. This process has traditionally used platinum alloys as catalysts. Alloys are used industrially because they have a greater selectivity than monometallic platinum. Alloying platinum with an inactive promoter modifies the crystalline structure of the surface (geometric effect), and the 5d electrons in platinum responsible for chemistry (electronic effect); both have been suggested to be primarily responsible for dehydrogenation selectivity in platinum alloys. Alloy catalysts have been synthesized using early 3d transition metal promoters with the same Pt3M crystal structure. X-Ray Absorption Spectroscopy ...

Thermoelectrics And Thermoelectric Devices, Benjamin T. Erck May 2018

#### Thermoelectrics And Thermoelectric Devices, Benjamin T. Erck

##### Senior Theses

The field of thermoelectrics has many applications, and more are found in everyday systems. From its current studies, it is apparent that improving the figure of merit zT (which defines a good thermoelectric material) is important in the effectiveness of power generation. Another important part of thermoelectrics is the duality of these devices. They can both move heat and generate power, depending on their role in the system. In this thesis research, a process was made to test these thermoelectric relationships for a few Peltier devices in order to understand their efficiencies and what systems they can be applied to.

These calculations are discussed for simple examples and then extended to ﬁt the general wave equation with Robin boundary conditions. Ideas from Sobolev space theory are used to provide justiﬁcation of the method.

Saving Olivet Money With Creation Care, Nicholas Boros Apr 2018

#### Saving Olivet Money With Creation Care, Nicholas Boros

##### Scholar Week 2016 - present

Universities throughout the United States are searching for ways to reduce overhead costs, to help combat rises in tuition costs. Typically, one would think that installing solar panels on campus to help generate electricity would cost Olivet money, especially since the University is located in the Midwest. While such an undertaking would require an upfront investment, we will discuss how solar panels could save the University as much as $500,000 to$800,000 per year after an approximate 10 year break even point. We will also briefly discuss how similar approaches could be applied to other businesses and homes ...

#### Sustainability-Efficiency Paradox: The Efficacy Of State Energy Plans In Building A More Sustainable Energy Future, Austin Zimmerman

##### Pitzer Senior Theses

State energy plans are created at the request of a sitting governor or State Legislature in order to provide guidance set goals for the state’s energy sector. These plans will be critical indicators of energy trends such as the future market share of coal, natural gas, and renewables. If the future of energy in the United States is to be remotely sustainable, low-carbon policies must headline state plans. The strength of a state’s energy plan in terms of sustainability is directly related to that state’s willingness to prioritize and commit to incorporating energy sources that produce negligible ...

#### An Examination Of Ash Elutriation From A Fluidized Bed Regenerator, Dane Erickson

The danger of climate change looms in the minds of researchers across the world. To combat this threat, many have focused efforts on the development of clean energy. In this study, the renewable resource that is investigated is biomass, specifically red oak. Energy can be extracted from biomass by fast pyrolysis, where the feedstock is rapidly heated within a reactor to approximately 500℃ in the absence of oxygen. This produces biochar, ash, and condensable gases that, once cooled, become a bio-oil. To optimize economic feasibility, the process must operate continuously. This presents a problem—the presence of ash as a ...

#### Efficiency

##### Activities

The previous two activities in this module have shown us the importance of conservation laws. These laws provide extra “tools” that allow us to analyze certain aspects of physical systems and to be able to predict the motion of objects in the systems without using more complicated analysis. Even in situations wherein we cannot exactly solve the motion, these laws are incredibly useful. For instance, if someone shows us an incredibly complicated device that can seemingly produce electricity with no energy input whatsoever, we know not to invest money in this device, as it must be a sham since it ...

#### First Law Of Thermodynamics

##### Activities

In last week’s activity, we calculated the motion of objects by studying the forces on them. Using Newton’s Second Law of Motion, we were able to relate the forces on an object to the acceleration it experienced. The presence of constant forces led to constant accelerations, which corresponded to linearly-increasing velocities with respect to time. Comparisons made between the velocities we measured and those calculated from a study of the forces on the objects allowed us to validate Newton’s equation F = ma. In this week’s activity, we are going to investigate almost the same experimental setup ...

#### Newton's Second Law

##### Activities

There are two ways to study the dynamics of a system in which there is motion. One of these is to study the kinematics of the system to see if there is any acceleration. If there is an acceleration, then this implies that there is a net force on some part of the system. If there is no acceleration, then this means that either there are no forces on the system, or that the forces within the system are all balanced. The other way to study the system is from an energy standpoint. Energy can flow from potential to kinetic ...

#### Home Energy Capstone

##### Activities

The other three weeks of the Home Energy Module study energy flow and usage in our homes. In the R-Factor activity, we observed that the material used in the construction of our homes has a tremendous impact on the rate at which heat flows through its exterior surfaces. In Home Audit and Home Analysis activities, we performed an energy audit of our homes to estimate the amount of money that it costs to power it. As you have seen during our studies, there are many factors that affect the cost of energy in our homes. The right choices of materials ...

#### Home Energy Audit

##### Activities

In the 1800's, scientists found, empirically, that rules exist that determine how energy can be transferred. The first of these rules is called the First Law of Thermodynamics. This law is usually stated as, "Energy can neither be created nor destroyed; it can only be transferred from one form to another." This often leads to the re-titling of this law as the Conservation of Energy Principle since it says that energy must be conserved. This statement of the First Law does not say anything about how energy can be transferred, though. It turns out that there are only two ...

#### Gravitationally Induced Quantum Superposition Reduction With Large Extra Dimensions, Jonas R. Mureika

##### Jonas Mureika

A gravity-driven mechanism (objective reduction'') proposed to explain quantum state reduction is analyzed in light of the possible existence of large extra dimensions in the ADD scenario. By calculating order-of-magnitude estimates for nucleon superpositions, it is shown that if the mechanism at question is correct, constraints may be placed on the number and size of extra dimensions. Hence, measurement of superposition collapse times ({\it e.g.} through diffraction or reflection experiments) could represent a new probe of extra dimensions. The influence of a time-dependent gravitational constant on the gravity-driven collapse scheme with and without the presence of extra dimensions is ...
