Actividad 1: Más Fresco Que Yo, Patrick Young

Tema 4: Por favor, pásame la sal

La materia está formada por átomos y moléculas. Aunque no podremos verlas con nuestros ojos, estas pequeñas partículas se mueven constantemente. La temperatura de una sustancia es una medida de su energía cinética promedio (la energía que tiene debido al movimiento de las partículas). A medida que aumenta la temperatura, las partículas adquieren más energía, se mueven más rápidamente y se separan más.

No importa en qué lugar de Illinois viva, el clima invernal nos impacta a todos. El deshielo y la limpieza de nieve representan una gran parte del presupuesto para las carreteras estatales y locales. La sal se …

Actividad 2: Ruta Óptima, Patrick Young

Tema 2: Por la ciudad

Los sistemas de navegación de los vehículos utilizan información de la ubicación para ayudar a los conductores a decidir qué ruta tomar. Muchos de los sistemas de navegación alertan a los conductores de peligros en la carretera. Los cierres de carreteras, los accidentes, el clima y otros peligros afectan tanto los tiempos de viaje como las rutas elegidas. La colaboración y el intercambio de información entre la autopista o carretera, los servicios públicos y los sistemas de navegación son necesarios para informar a los conductores.

Activity 4: High Visibility Signs, Patrick Young

Theme 2: Around Town

Highway signage has evolved over time in response to driving habits and advances in automotive technology and materials science. Although most informational signs have a nondescript appearance, the microscopic structure of their surfaces is complex. Many competing designs attempt to provide advantages when illuminated by headlights.

It is often true that designing a test to evaluate different items is as important and challenging as designing the items themselves. In this activity, students will design both highway signs and a reliable procedure for testing them.

Activity 1: Traffic Jam, Patrick Young, Peg Steffen

Theme 3: Traffic Management

Computer models can be excellent tools for analyzing complex systems. In this activity, students will use a web-based computer model to explore the relationship between the volume of traffic and the time it takes for vehicles to get from point A to point B. Then they will use the model to assess two potential solutions to their particular example of traffic congestion. Students will be comparing small samples with larger samples to appreciate the benefits of using large, random samples.

Architecture Of Heptagonal Metallo-Macrocycles Via Embedding Metal Nodes Into Its Rigid Backbone, A.M.Shashika D. Wijerathna, He Zhao, Qiangqiang Dong, Qixia Bai, Zhiyuan Jiang, Jie Yuan, Jun Wang, Mingzhao Chen, Markus Zirnheld, Rockwell T. Li, Yuan Zhang, Yiming Li, Pingshan Wang

College of Sciences Posters

Metal-organic macrocycles have received increasing attention not only due to their versatile applications such as molecular recognition, compounds encapsulation, anti-bacteria and others, but also for their important role in the study of structure-property relationship at nano scale. However, most of the constructions utilize benzene ring as the backbone, which restricts the ligand arm angle in the range of 60, 120 and 180 degrees. Thus, the topologies of most metallo-macrocycles are limited as triangles and hexagons, and explorations of using other backbones with large angles and the construction of metallo-macrocycles with more than six edges are very rare.

In this study, …

Production Of Lithium Carbonate From Geothermal Brine By Selective Extraction Of Lithium Using A Novel Ion Sieve Method, Ujjwal Pokharel, Sandeep Kumar

College of Engineering & Technology (Batten) Posters

The project implements a novel approach to extract lithium from a geothermal brine with minimal water loss. Production of high-capacity lithium-ion (Li-ion) batteries for electric vehicles (EV) is believed to be the way to reduce dependence on fossil-fuel based vehicles. Currently, most of the lithium in the world comes from the mining of lithium or the evaporative/concentration of the brine. Mining is not environmentally friendly, and the evaporative process takes 12 months for the completion of the extraction process and results in a large amount of water loss which can lead to scarcity of water. The brines constitute 82% of …

Actividad 4: Reduzca La Velocidad, Se Aproximan Curvas, Patrick Young

Tema 2: Por la ciudad

Diseñar una carretera conlleva tomar muchas decisiones. En un mundo ideal, todas las carreteras tendrían una superficie plana y recta. Lamentablemente, no es así porque las carreteras tienen muchos desvíos, intersecciones, numerosos automóviles transitando y semáforos. Los ingenieros eligen la velocidad máxima de la carretera en función de las características de equilibrio del terreno, el tráfico, los obstáculos existentes y, lo que es más importante, la seguridad.

El objetivo principal de una carretera es asegurarse de que los vehículos puedan maniobrar a una velocidad determinada de forma segura. Por ejemplo, no verá un límite de velocidad de 60 millas por …

Actividad 2: Solo De Paso, Patrick Young

Tema 5: ¿Por qué la gallina cruzó la calle?

Los pasos para animales para la fauna silvestre son cada vez más frecuentes. Su objetivo es proporcionar un camino seguro para que los animales crucen las barreras hechas por el hombre, en este caso las carreteras. Las escaleras para peces, patentadas en 1837, son un ejemplo temprano de este tipo de intervención. Además, los pasos proporcionan a los animales el acceso a los recursos del otro lado de la barrera. Los pasos ayudan a conectar los hábitats para evitar la fragmentación de los mismos, lo que puede restringir el acervo genético y dar lugar a poblaciones más bajas y en …

Activity 5: Slow Down, Curves Ahead, David Hernandez, Peg Steffen

Theme 2: Around Town

Highway curves are banked so the outside edge of the roadway is elevated above the inside edge. This provides additional centripetal force to keep the car on the road and following the proper path. The faster a car is moving, the more banking it will need.

Activity 3: Warning!, Elizabeth Martinez

Theme 5: Why Did the Chicken Cross the Road?

More factors than previously mentioned must be considered in the design of an animal crossing structure, such as temperature, precipitation, vehicle traffic, noise, and vehicle exhaust. Consideration of these environmental factors and events will require modifications to the original design. This is a common practice in engineering. The original design might go through several revisions as modeling, testing, and experience reveal the need for modifications.

Actividad 4: Prueba De Las Cubiertas De Hormigón Fabricadas Por Los Estudiantes, Patrick Young

Tema 1: Estructura y proceso

Cuando una viga estructural se carga desde arriba, la fuerza crea compresión en la superficie superior y tensión en la superficie inferior. El hormigón puede soportar la compresión diez veces más que la tensión. Como el hormigón tiene menos capacidad para soportar la tensión, el refuerzo de acero es más importante en la parte inferior.

En esta actividad, los estudiantes realizarán una prueba de carga en 3 puntos para ver cuánto peso pueden soportar sus losas.

Actividad 3: Curva Pronunciada, Patrick Young

Tema 2: Por la ciudad

La forma de una curva afecta la facilidad con la que un automóvil puede circular con seguridad por ella. Las colisiones son más probables cuando la curva es demasiado cerrada. La curva debe ser suave, la transición entre los tramos rectos y curvos de la carretera también deben ser suaves.

En la imagen anterior, el automóvil experimenta una fuerza (llamada “fuerza centrípeta”) que lo empuja hacia el centro del círculo. Se trata de una fuerza de fricción proporcionada por la carretera que actúa sobre los neumáticos. Cuanto más cerrada es la curva, más fricción se necesita para mantenerse en la …

Activity 1: Adela Valley Highway, Patrick Young, David Hernandez

Theme 2: Around Town

If you ask a longtime resident of your neighborhood what the town was like 30 or 40 years ago, they will tell you that there were a lot of empty spaces or fields. Ask them if they are happy with the numerous homes, businesses, roads, and industries that now exist. They may say that they lost part of their community. At the same time, they gained jobs, property value, and infrastructure improvements.

Whether to build more roads through a town is not an easy decision. There has to be a clear implementation plan, local or state funding, city code agreement, …
