As the nature and quantity of new/novel nanomaterials continue to expand to meet industrial, medical, and domestic demands, their accidental or intentional release becomes inevitable. To this end, an evolving understanding of the interaction dynamics between nanomaterials and naturally occurring geomaterials is central to supporting continued sustainable development and use of nanomaterials. The current study explores the chemodynamics of the organic nanomaterial, polyamidoamine (PAMAM) dendrimers, binding to (and debinding from) ferrihydrite. Specific focus is placed on how PAMAM size and pH affects the reaction between three carboxyl-terminated PAMAMs (Gx.5-COOH) sorbing/desorbing to/from the variably-charged ferrihydrite (FFH). Since both ferrihydrite and PAMAM exhibit pH-dependent variation of speciation, it is expected that binding/debinding dynamics of differing sizes of PAMAM will vary. Investigating the quantity, rate, and dynamics of these reactions provides insight into the type of bonding occurring (physiosorption, electrostatic bonding, or hydrogen bonding) and the location of bonding (surface versus micropore spaces). The information gained from this study will help to develop a more holistic picture of the environmental fate of synthetic nanomaterials.

This research will examine the change in size of local aquifers in Texas to determine how drought affects crop yield in Texas, for the aquifers scattered about Texas are the major source of irrigation for farmers in the state. This will be demonstrated by assessing conditions in the San Antonio area (as a case study) due to the severe drought that has affected the area for the past couple of months. Several spatial datasets including remote sensing datasets and results derived using different analysis tools in GIS will be utilized to demonstrate the change in aquifer size and volume during the investigated period.

More meteorites are found in North-West Africa every year than in any other location on the earth’s surface. These meteorites are sold and will either enter a scientific collection, or that of a private collector. In the latter case, a meteorite may never be officially classified, which means that it is not recognized by the scientific community as a new meteorite find.. The meteorite classification process is led by the Meteoritical Society, who nominate meteorite researchers to serve on the Meteorite Nomenclature Committee. This committee is responsible for the peer review of all meteorite classification submissions, and to ensure the donation of a scientific repository sample. After this, an official name is assigned and the meteorite is entered into the Meteoritical Bulletin Database (MetBull). MetBull is an archive of all meteorites recognized by the Meteoritical Society and contains basic information about each meteorite; for example, its classification, the location it was found, and a brief description of the sample studied.

The Monnig Meteorite Collection at TCU contains a number of unclassified meteorite samples. In this study, we will examine three unknown meteorites and determine the meteorite type in terms of: (1) the type of body they come from, (2) the minerals and textures they contain, (3) their mineral compositions and, (4) their thermal history. This data will then be submitted to the Meteorite Nomenclature Committee for official classification.

Crafts & Conversations was established to foster community among TCU students and the residents of a local retirement facility, Trinity Terrace. During monthly meetings, students and residents share their stories while collaborating on engaging craft activities, including murals, cross-stitching, snow globes, suncatchers, pillows, and upcycled terrariums. TCU students who volunteer in these monthly meetings build meaningful friendships, combat stereotypes against the elderly, and improve communication and leadership skills. In addition, each event opens with a performance by TCU music students, enabling them to cultivate their craft and share their talent. Even throughout the pandemic, Crafts & Conversations nurtured memories and connections through Zoom and masked in-person meetings. With a commitment to sustainability, this project will continue to enrich the lives of Trinity Terrace residents and provide dedicated student volunteers with opportunities to strengthen the Fort Worth community.

Mercy Clinic of Fort Worth is a free health clinic that provides care to the underserved population, largely comprised of uninsured adults, in south Fort Worth. Services at Mercy Clinic include wellness checkups, sick visits, and well-woman visits, as well as some dental procedures, labs, and prescription services. TCU students of the Pre-Health Professions Institute consistently volunteer at Mercy Clinic, and TCU’s relationship with Mercy Clinic has continued to grow especially with the new addition of TCU’s Burnett School of Medicine to the Fort Worth community. A current collaboration between Mercy Clinic and the Burnett School of Medicine is aimed at providing clinics for women to get well-women exams such as pap smears and breast exams. Funds provided by the Experiential Projects to Impact the Community (EPIC) Grant were used to assist with the cost of supplies, such as speculums and drape sheets, for these women’s clinics. The goals of this community project are to serve the Fort Worth community by providing Mercy Clinic with materials and volunteers, to emphasize the importance of women’s health and knowledge about it, and to grow TCU Pre-Health’s relationship with the Burnett School of Medicine and Mercy Clinic.
