Rice University Research Repository


The Rice Research Repository (R-3) provides access to research produced at Rice University, including theses and dissertations, journal articles, research center publications, datasets, and academic journals. Managed by Fondren Library, R-3 is indexed by Google and Google Scholar, follows best practices for preservation, and provides DOIs to facilitate citation. Woodson Research Center collections, including Rice Images and Documents and the Task Force on Slavery, Segregation, and Racial Injustice, have moved here.

Additive manufacture-assisted method for making structural elements having controlled failure characteristics
(2024-06-18) Sajadi, Seyed Mohammad; Meiyazhagan, Ashok Kumar; Boul, Peter; Rahman, Muhammad; Thaemlitz, Carl; Ajayan, Pulickel; Rice University; Saudi Arabian Oil Company; United States Patent and Trademark Office
A process for making a layered multi-material structural element having controlled mechanical failure characteristics. The process includes the steps of: supplying a cementitious layer and forming a polymer layer on the cementitious layer by additive manufacture such that the polymer layer has a first thickness and the cementitious layer has a second thickness, wherein the polymer layer comprises a polymer and the cementitious layer comprises a cementitious material; and allowing the polymer from the polymer layer to suffuse into the cementitious layer for a period of time to obtain a suffused zone in the cementitious layer such that the suffused zone has a third thickness that is less than half the second thickness.

(2024-06-18) Tour, James M.; Chyan, Yieu; Arnusch, Christopher John; Singh, Swatantra Pratap; Li, Yilun; Luong X, Duy; Kittrell, Carter; Ye, Ruquan; Miller, Jordan; Kinstlinger, Ian; Cofer, Savannah; Rice University; B.G. Negev Technologies and Applications Ltd. at Ben-Gurion University; United States Patent and Trademark Office
Methods that expand the properties of laser-induced graphene (LIG) and the resulting LIG having the expanded properties. Methods of fabricating laser-induced graphene from materials, which range from natural, renewable precursors (such as cloth or paper) to high performance polymers (like Kevlar). With multiple lasing, however, highly conductive PEI-based LIG could be obtained using both multiple pass and defocus methods. The resulting laser-induced graphene can be used, inter alia, in electronic devices, as antifouling surfaces, in water treatment technology, in membranes, and in electronics on paper and food Such methods include fabrication of LIG in controlled atmospheres, such that, for example, superhydrophobic and superhydrophilic LIG surfaces can be obtained. Such methods further include fabricating laser-induced graphene by multiple lasing of carbon precursors. Such methods further include direct 3D printing of graphene materials from carbon precurors. Application of such LIG include oil/water separation, liquid or gas separations using polymer membranes, anti-icing, microsupercapacitors, supercapacitors, water splitting catalysts, sensors, and flexible electronics.

Houston and Harris County Residents' Experiences with Perceived Crimes and Incidents Motivated by Bias and Prejudice
(Rice University Kinder Institute for Urban Research, 2024) Perez, Katherine; Potter, Daniel
Against a backdrop of concern for crime and low levels of hate crime reporting, residents in Houston and Harris County were asked about their experiences being the victim of a crime or other unwanted incident (or both), and whether they perceived those experiences being motivated by bias or prejudice towards one of their actual or perceived characteristics. Additionally, for residents who reported being the victim of a crime or incident they perceived as being motivated by bias or prejudice, they were also asked if they reported the incident to the police or other local law enforcement, and if not, what stopped them from reporting.
