School of Engineering Department of Chemical and Biological Engineering 85 Development of Shower Pills (Instead of Gel or Soap) Supervisor: LUO Zhengtang and LIU Y.S. Marshal / CBE Student: TSANG Hoi Lam Tammy / CHEM WONG Yung Tat Vincent / SENG Course: UROP1000, Summer UROP1000, Summer This report will focus on the development of shower pills including the selection of chemical ingredients based on literature review, the formation of shower pills based on different trials, the shortcomings and merits of the shower pills, the problem we face and the improvements we can make. Overall, the development of shower pills is not very successful. Only two out of eight trials can form a pill successfully and the pill becomes sticky when pressure is applied to it. This is because of the chemicals' characteristics, which leads to a paste-like texture performed by the shower pills and a long dissolving time. We believe that a change in chemicals and improvement in equipment can ease the problems we face. Advanced Catalysts for Water Splitting and Hydrogen Production Supervisor: SHAO Minhua / CBE Student: KIM Hyeongwoo / CENG Course: UROP1100, Fall As the movement for the decrease in carbon footprint rises, alternative fuels for various applications are available and investigated in modern society. Electrochemical hydrogen evolution reaction (HER) is considered a renewable and feasible way of generating hydrogen fuels for the future. Various types of catalysts used for the reaction have been extensively discussed for previous decades. Pt/Ru bimetallic catalyst is well known for its promising performance, but the effects of annealing temperature, which is used for pyrolysis of catalyst production, on HER performance has not been discussed in the literature. In this project, Pt/Ru bimetallic catalysts are produced with different annealing temperatures, and its electrochemical active sites and HER performances are discussed through cyclic voltammetry and linear sweep voltammetry. Advanced Catalysts for Water Splitting and Hydrogen Production Supervisor: SHAO Minhua / CBE Student: YANG Jianbo / CENG Course: UROP1100, Fall Carbon dioxide is one of the greenhouse gases causing global warming due to its ability to absorb infrared light from the Earth and return some of it, causing the Earth to heat up. Researchers nowadays pay more attention to electrochemical reduction of carbon dioxide for solving problems like means of energy storage or environmental issues. Advanced catalysts design is a popular research topic since different compositions and structures will have different effects on products. Therefore, finding an economical and efficient catalyst is significant to current research, even to industrial production. In this program, my supervisor and I focused on synthesizing Pd/C nanoporous catalysts loaded with pyridine-derivatives and analyzing their performances under a series of voltages in electrochemical reduction reaction.
