Design And Perspective Of Amorphous Metal Nanoparticles From Laser Synthesis And Processing, Shun-Xing Liang, Lai-Chang Zhang, Sven Reichenberger, Stephan Barcikowski

Research outputs 2014 to 2021

Amorphous metal nanoparticles (A-NPs) have aroused great interest in their structural disordering nature and combined downsizing strategies (e.g. nanoscaling), both of which are beneficial for highly strengthened properties compared to their crystalline counterparts. Conventional synthesis strategies easily induce product contamination and/or size limitations, which largely narrow their applications. In recent years, laser ablation in liquid (LAL) and laser fragmentation in liquid (LFL) as "green"and scalable colloid synthesis methodologies have attracted extensive enthusiasm in the production of ultrapure crystalline NPs, while they also show promising potential for the production of A-NPs. Yet, the amorphization in such methods still lacks sufficient rules …

Garden Helper Robot (Ghr), Tye Foster, Matthew Jacques, Joshua Mecham

Electrical and Computer Engineering

Engineer Joshua Mecham's grandfather Jerry Hansen loves to garden; however, Jerry's arthritis prevents him from pursuing his passion.

There had to be some way to incorporate an ordinary hose box into a mobile gardening bench. This solution would simultaneously water Jerry’s plants as well as provide a seat Jerry could use instead of getting on his hands and knees.

For this reason, the GHR was designed with people like Jerry in mind that want to continue their hobbies despite disabilities/sickness/age troubles.

Infant Earmuff System, Beth Powell

Electrical and Computer Engineering

The Infant Earmuff System allows caretakers to prevent hearing damage in infants when wearing the device.

• Infants have smaller ear canals and are therefore more susceptible to hearing damage than adults
• Hearing damage in infants is permanent but infants are bad at communicating if the noise level is too loud.
• The Infant Earmuff System allows caretakers to understand the level of noise an infant is hearing and whether that level is dangerous.

Real Life Jrpg, Jacob Wilson

Electrical and Computer Engineering

JRPG is a very popular video game genre, it’s turn based battle system allows the player to create interesting strategies impossible to find in real time games.

The goal of Real Life JRPG is to bring that experience away from the TV. Fight a dragon by actually swinging a sword.

Up to 3 players will work together to defeat the dragon, attacking it will Lower it’s health points and if the Dragons health points reach 0 the players win. But the Dragon will retaliate and if all players lose their health points, the dragon win.

Making Loud Noises Quiet, Logan Voigt, Nicholas Williams

Electrical and Computer Engineering

Guns are loud. Putting on ear protection takes time. Hunters need to listen for animals, so they can not wear ear protection constantly. Hunters have limited time to react when they see their target. They do not have time to put on ear protection. The Shot Silencer protects hunters’ hearing by actively noise cancelling the sound of the gunshot.

Walkmatic, Chaz Cornwall, Ryan Berg

Electrical and Computer Engineering

The Walkmatic is a baby push toy with automated steering to keep babies from pushing the toy into walls or down the stairs. Parents who are anxious to watch their child learn how to walk will often buy push toys to help their child stand up while they learn to walk. Unfortunately, parents must constantly guide the push toy to prevent the baby from pushing it into obstacles. This can take a toll on parents’ backs and knees. With the Walkmatic, parents can relax while they watch their baby play with their fun new toy.

When the Walkmatic is first …

Preconstruction Plan For Stairs At West Cerro Vista Apartments, Kian D. Kemp

Construction Management

Students at California Polytechnic University have created an unsafe dirt trail down a hillside west of the Cerro Vista Apartment Complex on the university’s campus. This heavily traveled trail is a shortcut to an existing pedestrian pathway which connects Village Drive to Poly Canyon Village, as well as the R-3 and R-4 parking structures. The use of this trail raises alarm for potential safety concerns for students using it, especially during winter months when the hillside becomes very slippery. This paper outlines the design and preconstruction plan for the West Cerro Vista Stair Project, which proposes replacing the current trail …
