Abstract: The frequency and intensity of wildfires has increased over the past few decades. Wildfires represents an acute perturbation to watersheds, and the impacts include changes in ecosystems, sediment mobilization and overall water quality. The changes in water quality are a particular concern to drinking water utilities. The changes in water quality can have profound effects on the ability of a drinking water utility to produce water that meets US EPA regulations. Over the past, 6 years, my group has studied the impacts that wildfires can have on water quality and treatment operations. One of the concerns regarding wildfires is the changes that are observed to the soil matrix and the resulting enhancement in the mobilization of dissolved organic matter (DOM). In this presentation, a general discussion regarding the effects of wildfires on water quality will be presented, followed by a detailed discussion regarding the specific effects that thermal alteration has on DOM mobilization.

Biography: Dr. Fernando L. Rosario-Ortiz is an Associate Professor of Environmental Engineering at the University of Colorado-Boulder. Dr. Rosario received his BS and MS in Chemistry from the University of Puerto Rico and the California Institute of Technology, respectively. He received his doctoral degree from UCLA in environmental science and engineering in 2006. His current research focuses on environmental photochemistry, impact of watershed perturbations on water quality and characterization of organic matter in different environments.


Richard C. Tolman Award Dinner Meeting

“Multifunctional Mesoporous Silica Nanoparticles Controlled by Nanomachines for
Biomedical Targeting, Imaging and Drug Delivery”

Professor Jeffrey Zink
UCLA Department of Chemistry and Biochemistry

UCLA Faculty Center
480 Charles E. Young Drive, East
Los Angeles, CA 90095

6:00 p.m. Check-in and Hosted Social Hour
7:00 p.m. Dinner
8:00 p.m. Presentation

The Award: The Richard C. Tolman Medal is awarded each year by the Southern California Section of the American Chemical Society in recognition of outstanding contributions to chemistry in Southern California. The Tolman Medal recognizes broad accomplishments in chemistry rather than a single fundamental discovery. These contributions may be of several kinds, including seminal research of widely regarded influence, achievements of broad impact in chemical technology, significant contributions to chemical education, and outstanding leadership in science on a national level. To be eligible for the Medal, the recipient must have accomplished a major portion of his or her work while a resident of Southern California.

Abstract: The subjects of this talk are multifunctional nanoparticles controlled by nanomachines for targeting, imaging and drug delivery in cells and in vivo. The nanoparticles are designed to 1) trap therapeutic molecules inside of nanocarriers, 2) carry therapeutics to the site of the disease with no leakage, 3) release a high local concentration of drugs, 4) release only on autonomous or external command, and 5) kill the cancer or infectious organism. The most important functionality is the ability to trap molecules in the pores and release them in response to desired specific stimuli. Two types of external stimuli will be discussed: light and oscillating magnetic fields. Activation by internal biological stimuli such as pH changes, redox potential changes and enzymes will also be presented. Molecular machines based on molecules that undergo large- amplitude motion when attached to mesoporous silica – impellers, snap-tops and valves – will be described. Derivatized azobenzene molecules, attached to the interior pore walls function as impellers that can move other molecules through the pores. Nanoparticles containing anticancer drugs in the mesopores are taken up by cancer cells, and optical stimulation of the impellers drives out the toxic molecules and kills the cells. Snap-tops with cleavable stoppers release cargo molecules when the stopper is removed from the pore entrance. Nanovalves consisting of rotaxanes and pseudorotaxanes placed at pore entrances can trap and release molecules from the pores in response to stimuli. Activation of these nanodevices by the five types of stimuli in solution, in living cells, and in animal models will be discussed. Applications to treatments of cancers (including pancreatic and breast) and of intracellular infectious diseases (including tuberculosis and tularemia) will be presented.

Cost: There is a choice of dinner entrees of Marinated Grilled Rib-Eye Steak with veal demi glaze, potatoes and asparagus ($44) or Pan Roasted Salmon with herbs and grilled asparagus ($48) or Moroccan Spiced Vegetable Tagine—Saffron couscous, squash, celery root, garbanzo beans and tomatoes ($38). All options include a hosted social hour, salad, dessert, wine with dinner and tax and tip, payable at the door with cash or check. Please RSVP to Nancy in the Section Office at by Monday, April 16, 2018.

High School Chemistry Olympiad

The Southern California Section of the American Chemical Society has been offering the Chemistry Contest since 1914, at which time Nordhoff High School was the top scoring school. It became the High School Chemistry Olympiad in 1968 when National ACS began sponsoring it. In 2008, the Section won a National award for 25 years of continuous support of the Chemistry Olympiad. In 2014, we celebrated 100 years of offering the High School Contest. The Southern California Section has the longest running contest in American Chemical Society history.

This year, the Southern California Section will hold the High School Chemistry Olympiad on Wednesday, March 21st and Thursday, March 22nd at over 35 schools in the Los Angeles area. The test is designed to test a student’s knowledge of a wide variety of topics in chemistry. If you know of a school or student that would like to participate, please direct them to our website, to download the letter and participation form. We now offer the option to pay with a credit card online. The top scorers on the local exam are nominated to compete in the National Exam which will take place on April 21st, 2018. The top 20 national winners are invited to attend an all expense paid two-week study camp at the U. S. Air Force Academy in Colorado Springs, Colorado. The top four finalists are then selected to represent the United States at the International Chemistry Olympiad which will be held in Bratislava, Slovakia and Prague, Czech Republic, July 19-29, 2018.

We will recognize the top local students at our Educational Awards Banquet to be held on May 18th, 2018 with monetary awards and certificates. The Banquet will take place at the Mount Saint Mary’s University Doheny campus. For more information, please contact Dr. Jerry Delker at or Nancy Paradiso in the Section Office at
