When it comes to installing solar cells, labor cost and the cost of the land to house them constitute the bulk of the expense. The solar cells – made often of silicon or cadmium telluride – rarely cost more than 20 percent of the total cost. Solar energy could be made cheaper if less land had to be purchased to accommodate solar panels, best achieved if each solar cell could be coaxed to generate more power.
A huge gain in this direction has now been made by a team of chemists at the University of California, Riverside that has found an ingenious way to make solar energy conversion more efficient. The researchers report in Nano Letters that by combining inorganic semiconductor nanocrystals with organic molecules, they have succeeded in “upconverting” photons in the visible and near-infrared regions of the solar spectrum.

A team of students from the University of California, Riverside’s Bourns College of Engineering recently won two awards at an international design competition for a material composed of rice husks that they created as a less costly and more environmentally friendly alternative to particleboard.
In the students’ design, the rice husks, which contain termite-resistant silica, replace wood chips found in traditional particleboard. The students then use environmentally friendly binding materials instead of traditionally used glues that contain formaldehyde, known to emit harmful gases into the air.
Initial cost estimates compiled by the students show four-by-eight-foot rice husk boards would cost about $18. Currently, four-by-eight-foot particleboard sheets sell for about $25 in the United States. While the main focus of the project is to create a building material for relief structures in the Philippines, the students believe there could be a market in the United States to use the boards for furniture.
“What we are creating is a really a win-win situation,” said Joel Sanchez, a senior chemical engineering major and a member of the team. “It will last longer, be environmentally friendly and cost less.”
In addition to Sanchez, the team consists of Lamees Alkhamis, Colin Eckerle, Jeniene Abugherir and Chris Yang. All except Eckerle expect to graduate in June. They are advised by Kawai Tam, a lecturer at the Bourns College of Engineering; Michael Rust, a distinguished professor at the Department of Entomology; and David Kisailus, an associate professor at the Department of Chemical and Enviornmental Engineering.
The team, called Husk-to-Home, won two awards, including the Intel Environmental Innovation Award, the top award, and $5,000 at the WERC: A Consortium for Environmental Education and Technology Development competition in Las Cruces, N.M.
The idea for the project came from one of Tam’s former students, whose father-in-law’s brother runs a nonprofit, the International Deaf Education Association, in the Philippines that builds temporary housing after natural disasters.
One problem the nonprofit has is that its building materials, such as coconut wood, bamboo and plywood, are susceptible to termite damage.
Since the Philippines is one of the world’s largest producers of rice and previous research has shown that rice husks and rice straw are termite resistant the idea was to develop a particleboard-like material with the waste products of rice.
Initially, this was a makeshift project, in large part because the students didn’t have much money to put into it.
That wasn’t a problem with regard to the rice husks, which they purchased at a feed store. A 45-pound bag sells for $12. The rice husks are typically used as bedding for farm animals.
But the students needed $10,000 for a hot press that would allow them to assemble the risk husk boards in a uniform manner. They improvised, using a combination of nine-by-thirteen baking pans, spring form baking pans, ovens and blow torches.
They also built a makeshift humidity chamber to simulate conditions in the Philippines. The team built the chamber using a plastic container the size of a large shoebox, small fan, heating lamp, humidifier and humidity and temperature sensors. They drilled holes for air and the sensors.
The other challenge the students faced was acquiring termites. They said they were more expensive than expected – $1 to $1.50 per termite – if ordered through the mail and there was no guarantee they would arrive alive.
So the students worked with Rust to collect termites. But, they faced an additional problem: termites are dormant from roughly November to March.
Initially, the students used epoxy, a not-so-environmentally-friendly material, as the binding agent. Now, they are focused on using tannin, a compound naturally found in plants, and casein, a protein found in milk. For the casein experiments they use nonfat instant dry milk they buy at a grocery store.
By March, the students had raised $10,000 to buy the hot press. Once the press arrived, they immediately began experimenting with risk husk boards made with tannin and casein.
Initial results show that tannin boards are strong enough but not water resistant, while casein boards are water resistant but not strong enough.
The students are experimenting with adding coatings or other materials to the mixture. Options include adding shrimp shells, which are abundant in the Philippines. They also plan to add a water resistive coating to eliminate problems with the particleboard falling apart in the humid environment. In addition, they want to incorporate rice straw, which could increase strength and flexibility.
Creating a new way to make particle board is a great example of Seizing Our Destiny’s catalyst for innovation pillar. The people and educational institutions of Riverside cultivate and support useful and beneficial idea, research, products, and scholars.

“I love the Wood Streets because of the traditional design and landscape.” These are the kinds of comments received on postcards written by City residents for the Neighborhood Postcard Project – a global participatory art project that fosters community connection through storytelling exchange. Residents share personal positive stories about their neighborhood on a postcard and those postcards are delivered to random people in different neighborhoods within the same city.
TheUnified City pillar group of Seizing Our Destiny has been collecting these postcards since the NeighborFest event held on May 16th. The City of Riverside has 26 neighborhoods. They are being collected two ways: via a handwritten postcard with a blank space on the back for creativity and through the Seizing our Destiny website. The ones collected on the website are being shared via social media.
The goal of the project is to build community connections, awareness and pride in our local treasures – our neighborhoods.
Art and history come together as several utility boxes in the downtown area are “wrapped” with art reproductions from the early 1900s reflecting our singular history. Themes include our citrus heritage, social justice exemplified in the preserving of the Harada House, military history remembered by Camp Anza, the Gage Canal, and Riverside’s thriving business and educational interests. All art work is derived from the Library’s archives. Sponsored by a local business, each box displays a digital code referring the viewer back to our website detailing the background of the historical images represented on each box. Each box displays a small map showing the location of the other box’s in the area. An online map enables virtual and actual walking tours. The exhibit is planned to be unveiled in November 2015—just in time for the Festival of Lights. An inventive addition to this project is the creation of a “how-to manual” for others who may be interested in creating similar thematic box art in Riverside. This project will serve as a 3-year pilot to pave the way for beautiful public art throughout Riverside, enhancing a lasting and attractive sense of place.
The mantis shrimp is able to repeatedly pummel the shells of prey using a hammer-like appendage that can withstand rapid-fire blows by neutralizing certain frequencies of “shear waves,” according to a new research paper by University of California, Riverside and Purdue University engineers.
The club is made of a composite material containing fibers of chitin, the same substance found in many marine crustacean shells and insect exoskeletons but arranged in a helicoidal structure that resembles a spiral staircase.
This spiral architecture, the new research shows, is naturally designed to survive the repeated high-velocity blows by filtering out certain frequencies of waves, called shear waves, which are particularly damaging.
The findings could allow researchers to use similar filtering principles for the development of new types of composite materials for applications including aerospace and automotive frames, body armor and athletic gear, including football helmets.
The “dactyl club” can reach an acceleration of 10,000 Gs, unleashing a barrage of impacts with the speed of a .22 caliber bullet.
“The smasher mantis shrimp will hit many times per day. It is amazing,” said Pablo Zavattieri, an associate professor in the Lyles School of Civil Engineering and a University Faculty Scholar at Purdue University.
The researchers modeled the structure with the same mathematical equations used to study materials in solid-state physics and photonics, showing the structure possesses “bandgaps” that filter out the damaging effects of shear waves traveling at the speed of sound.
Findings were detailed in a research paper published online in the journal Acta Biomaterialia. The paper will appear in a future print issue of the journal.
The paper’s lead author was Purdue doctoral student Nicolás Guarín-Zapata and it was co-authored by Juan Gomez, a researcher from the Civil Engineering Department, Universidad EAFIT, Medellín, Colombia; doctoral student Nick Yaraghi from UC Riverside; Kisailus; and Zavattieri.
The research, which is ongoing and also will include efforts to create synthetic materials with filtering properties, has been funded by the National Science Foundation and the U.S. Air Force Office of Scientific Research.

Innovation and expression will take center stage when the Riverside Community College Dance Department presents Celebrate Dance, the annual student-choreographed showcase, at 7 p.m. Thursday through Saturday, May 28, 29 and 30.
The concert features pieces choreographed by RCC Dance students, as well as guest artist Daniel Cruz, from Seattle. The event features original music by Odesza with remixes by Ambassadeurs, Mazde & Hermitude. Cruz was a guest teacher and adjudicator in February, and returned in April to set the new work on the eager choreographers.
The students based their choreography on responses to the questions: What inspires you? What makes you move? What pushes you back? What stops you in your tracks?
Tickets are available at the box office, 951-222-8100, or at landispac.com. General admission tickets are $15. The price for students, senior citizens, RCC staff and faculty, and children, 3 and older, is $10. Parking on campus requires a permit, however, park-by-hour spots are available.
Events like this help make Riverside a location of choice for people seeking a city that supports that arts. Our community provides an abundance of opportunities to be amazed, inspired and entertained, including arts and cultural offerings.
Competing in the WGI Independent Marching World Division, RCC bettered Rhythm X from Columbus, OH and Pulse Percussion from Westminster, CA. The national championship competition concluded an undefeated 2015 season for the Tigers.
The 41-member team of percussionists presented an ecologically themed show titled Guardians of the Breath, which Gary Locke, director of the Marching Tigers, called “a kind of musical wake-up call,” a warning of the dangers of the human lifestyle habits killing off trees.
“It was an amazing, sophisticated (performance), yet accessible to spectators, fans and judges,” said Locke. “The production often moved at break-neck speed. The performance included the felling of futuristic-looking steel trees and ended on a hopeful note with the introduction of a new, young tree.”
RCC’s constant achievements help make the college and Riverside a location of choice for students seeking the best education for a reasonable price and a college that supports their passion.
Two of California Baptist University’s campus publications, The Banner newspaper and Pursuitmagazine, took home top national awards at recent journalism conferences in Los Angeles and New York City.
The Associated College Press awarded 1st place “Best of Show” awards to both The Bannernewspaper and Pursuit magazine, in those respective categories, and The Banner Onlineearned the 5th place award in the Best Website category. The 31st Annual ACP National College Journalism Convention was held in Los Angeles Feb. 26 to March 1. A complete list of winners is available by clicking here.
“This is really unprecedented in my experience that one program would be awarded 1st place Best of Show in both the newspaper and magazine categories,” said Dr. Michael Chute, director of the journalism & new media and public relations program. “It is the third year in a row that The Banner has been named the top ‘Best of Show’ newspaper at the ACP convention. This really speaks to the quality work our students do on the campus publications and the top honor three years in a row shows how consistent our students have been in producing quality publications.”
CBU’s constant achievements help make the university and Riverside a location of choice for students seeking the best education for a reasonable price.
In the California College Media Association convention Feb. 28, CCMA awarded seven CBU students for outstanding achievement in writing, photography and design. The Pursuit staff also earned an honorable mention in the Best Magazine category.
At its Spring National College Media Convention in New York City March 11-14, the College Media Association awarded Pursuit magazine 2nd place in Best Magazine Spread, as well as 3rd place in Best Overall Design for another magazine spread, which competed against design entries from newspapers, magazines, yearbooks and advertising.
Colleges and universities from across the U.S. enter publications in the ACP and College Media Association competitions each year.
Brain cancer. Not the diagnosis Cassie Nguyen was expecting as a sophomore at Riverside’s Martin Luther King High School. Neither was the debilitating surgery that saved her life.
Today, Nguyen is an honor student and School of Public Policy ambassador at the University of California, Riverside, where she will graduate in June. She is a 10-year cancer survivor, American Cancer Society advocate, and the creator of Spotlight On Hope Film Camp, a free film making program for pediatric cancer patients that until now has been held only in Los Angeles.
Nguyen hopes to bring the film camp to UC Riverside and the Inland Empire, and is screening short films written and produced by pediatric cancer patients in the program on Thursday, April 2, from 3:30 to 6:30 p.m. in Highlander Union Building 367. The event is free and open to the public. Parking is free in Lot 1; pick up parking permits at the Kiosk on West Campus Drive at the University Avenue entrance to the campus. Reservations are requested as seating is limited and may be made online. The screening is co-sponsored by University Honors and the Women’s Resource Center.
The Riverside resident said she hopes the screening will generate support to expand the program to the Inland Empire. She hopes eventually to establish a nonprofit foundation and offer film camps across the country.
Approximately 13,500 children are diagnosed with cancer each year in the U.S., and about 25 percent of them die, Nguyen said. Although Spotlight On Hope Film Camp does not reduce the death rate, it does provide a therapeutic outlet for pediatric cancer patients, she explained.
“I know how boring the hospital scene is,” Nguyen said, recalling the surgery to remove the tumor from her brain, a year of radiation and chemotherapy, and physical therapy to learn to write with her left hand and regain mobility to address on-going balance and difficult vision issues. “I wanted to do something to help kids take their minds off what was happening to them and give them something to look forward to.”
Nguyen suggested the film camp for young cancer patients while working as an intern for Think Ten Media Group, a production company based in Castaic that aims to use the power of media to create change and spread awareness of key issues.
She raised $700 to cover production costs of the first camp, held in September 2013, by selling plastic cancer bracelets to UCR faculty and students, family and friends in her junior year. She dedicated the first film camp to a younger cousin who died of sarcoma cancer at age 14.
Think Ten Media Group co-founders and filmmakers Ramon Hamilton and Jennifer Fischer helped Nguyen develop the Spotlight On Hope Film Camp for pediatric cancer patients at Children’s Hospital Los Angeles as part of their company’s arts education program. The UCLA School of Theater, Film and Television hosts the camp in Los Angeles.
When the film camp proved to be successful, Nguyen applied for and won a $10,000 scholarship from the Donald A. Strauss PublicService Scholarship Foundation in 2014, which funded 10 more film camps at UCLA. The foundation awards $10,000 scholarships to as many as 15 California college juniors annually to support public-service projects that the students carry out during their senior year.
Spotlight On Hope Film Camp allows patients to explore the art of green screen and special effects film-making while working in groups to create a short, green screen and special effects film. The participants, who range in age from 8 to 22, also learn about story/character development, camera technique, video and FX editing during three days of weekend classes.
“Being a pediatric patient myself, I understand how valuable a creative therapeutic outlet can be in the midst of your long, dreadful and difficult journey battling cancer,” Nguyen explained. “Spotlight On Hope Film Camp can help children live in a fantasy world that allows them to get away from all their troubles and create lasting memories.”
Nguyen efforts to put smiles on pediatric cancer patients faces is a great example of Seizing Our Destiny’s unified city pillar, she demonstrates that we’re a caring community that has compassion for all of its inhabitants, and engages with one another for a better life for all.
Viewpoints received a Best of Show Award March 1 at the Associated Collegiate Press National College Journalism Convention in Universal City, placing fourth among community college newspapers.
