Dr. Yomaira Pagán-Torres is a Professor of Chemical Engineering at the University of Puerto Rico at Mayaguez. She received her Ph.D. in Chemical Engineering from the University of Wisconsin-Madison in 2011, under the guidance of Prof. James Dumesic. At UW, her research focused on developing catalytic technologies for biomass conversion. Before her academic position at UPR, she worked as Senior Engineer for The Dow Chemical Company in the Feedstocks, Olefins, Chemicals, and Alternative Technologies Research and Development group in Freeport, Texas. Her research group combines materials synthesis, advanced characterization, and kinetic studies to design bifunctional heterogeneous catalysts for the activation of targeted functional groups within carbon-based feedstocks, such as lignocellulosic biomass, carbon dioxide, and plastic polymers. Her research, teaching, and service contributions have been recognized with the University of Puerto Rico-Mayagüez College of Engineering Distinguished Professor Award (2017 and 2020).
Specifically, insights on the effect of structural, surface, and electronic properties of Cu Ga2O3 ZrO2 catalysts and the role of metal-metal oxide interfaces in increasing methanol yields will be discussed.

"Tuning Heterogeneous Catalyst Surfaces for Chemical Conversions" by Yomaira Pagán-Torres
Lignocellulosic biomass and carbon dioxide have emerged as attractive carbon-based feedstocks for the sustainable production of fuels and chemicals. However, the complex structure of these feedstocks requires the development of catalytic materials that promote selective C-O, C-H, and C-C bond cleavage, while maintaining catalytic stability. Our research group focuses on developing strategies to address this challenge by combining materials synthesis, advanced characterization, and kinetic measurements to elucidate the mechanisms that govern selective C-O, C-H, and C-C bond activation over bifunctional catalysts in the conversion of biomass-derived substrates and carbon dioxide.
In this talk, I will present our work on developing catalytic strategies for deoxydehydration (DODH) and hydrodeoxygenation (HDO) of carbohydrate-derived alcohols and acids to platform chemicals. Specifically, I will discuss the HDO of biomass-derived substrates, such as 1,4-anhydroerythritol, tartaric acid, and glycerol over bifunctional catalysts comprised of a supported hydrogen dissociating metal center (Pd, Rh, Pt) coupled with a redox metal oxide center (MoOx, ReOx, WOx). Our results, based on the combination of catalyst synthesis, kinetic measurements, and advanced characterization highlight the role of the noble metal, metal oxide species, and catalyst support in promoting selective C-O bond cleavage.
In the second part of the talk, I will present our latest efforts on developing Cu-based mixed-metal oxide catalysts for converting carbon dioxide to methanol. Specifically, insights on the effect of structural, surface, and electronic properties of Cu/Ga2O3/ZrO2 catalysts and the role of metal-metal oxide interfaces in increasing methanol yields will be discussed.

Its combination of learning activities, portability, and durability make it a valuable asset for parents and caregivers who want to provide engaging and educational experiences for their young children..
Reviews for "Enhancing Parent-Child Interaction with Playskool Magic Screen Palm Device"
1. Sophie - 2 stars
I was very disappointed with the Playskool magic screen palm device. The educational content seemed outdated and not engaging at all. My child quickly lost interest in it and preferred to play with other toys. Additionally, the screen was quite small and it was difficult for my child to see the images clearly. Overall, I would not recommend this device for educational purposes.
2. Mark - 1 star
I found the Playskool magic screen palm device to be a complete waste of money. The educational games were repetitive and did not provide any real learning value. The device itself felt cheap and the buttons were not very responsive. It also lacked any interactive features, which made it boring for my child to use. I would not recommend this device to anyone looking for an educational toy.
3. Emily - 2 stars
The Playskool magic screen palm device was a disappointment for me and my child. The educational games were too simple and did not challenge my child's learning abilities. The device also had a very short battery life and constantly needed to be recharged. The overall design was also not very user-friendly, with small buttons that were difficult for my child to press. I would not purchase this device again.
