Synthesis and Characterization of Vanadium Nitride/Carbon Nanocomposites.

Int J Mol Sci

June 2024

School of Earth Environmental and Marine Sciences, University of Texas Rio Grande Valley, 1 West University Blvd., Brownsville, TX 78521, USA.

The present work focuses on the synthesis of a vanadium nitride (VN)/carbon nanocomposite material via the thermal decomposition of vanadyl phthalocyanine (VOPC). The morphology and chemical structure of the synthesized compounds were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), Fourier transformed infrared spectroscopy (FTIR), X-ray diffraction (XRD), and X-ray photoemission spectroscopy (XPS). The successful syntheses of the VOPC and non-metalated phthalocyanine (HPC) precursors were confirmed using FTIR and XRD.

Synthesis and Characterization of Titanium Nitride-Carbon Composites and Their Use in Lithium-Ion Batteries.

Nanomaterials (Basel)

April 2024

School of Earth Environmental and Marine Sciences, University of Texas Rio Grande Valley, 1 West University Blvd., Brownsville, TX 78521, USA.

This work focuses on the synthesis of titanium nitride-carbon (TiN-carbon) composites by the thermal decomposition of a titanyl phthalocyanine (TiN(TD)) precursor into TiN. The synthesis of TiN was also performed using the sol-gel method (TiN(SG)) of an alkoxide/urea. The structure and morphology of the TiN-carbon and its precursors were characterized by XRD, FTIR, SEM, TEM, EDS, and XPS.

Memory interference theories hold that exposure to more similar information to a target item impairs memory of the target item. The dud effect refers to the finding in eyewitness lineup identification that fillers dissimilar to the suspect cause more false identification of the suspect than similar fillers, contrary to the interference concept. Previous studies on the Deese-Roediger-McDermott false memory typically showed a testing priming effect that a larger number of studied items presented at test leads to a higher level of false recognition of the critical lure (CL).

Department of Chemistry, PERL-Photonic and Energy Research Laboratory, The University of Texas Rio Grande Valley, 1201 West University Dr, Edinburg, TX, 78539, USA.

Due to unique photovoltaic properties, the nanostructured morphologies of TiO on flexible substrate have been studied extensively in the recent years for applications in dye sensitized solar cells (DSSCs). Microstructured electrode materials with high surface area can facilitate rapid charge transport and thus improve the light-to-current conversion efficiency. Herein we present an improved photoanode with forest like photoactive TiO hierarchical microstructure using a simple and facile hydrothermal route.

Evaluation of social and health risk factors of preschool children living along the Texas-Mexico border provides feedback to design health interventions.

Methods: South Texas Early Prevention Study-PreK (STEPS-PreK) is a cluster randomized trial designed to assess the effect of the Bienestar coordinated school health program on children's health outcomes.

Protozoan pathogen Trypanosoma cruzi (Chagas, 1909) is the etiologic agent of Chagas disease, which affects millions of people in Latin America. Recently, the disease has been gaining attention in Texas and the southern United States. Transmission cycle of the parasite involves alternating infection between insect vectors and vertebrate hosts (including humans, wildlife, and domestic animals).

Poly(lactic acid) (PLA) nanofiber scaffold has received increasing interest as a promising material for potential application in the field of regenerative medicine. However, the low hydrophilicity and poor ductility restrict its practical application. Integration of hydrophilic elastic polymer onto the surface of the nanofiber scaffold may help to overcome the drawbacks of PLA material.

This article demonstrates the use of hybrid nanofibers to improve the biodegradation rate and biocompatibility of AM50 magnesium alloy. Biodegradable hybrid membrane fiber layers containing nano-hydroxyapatite (nHA) particles and poly(lactide)(PLA) nanofibers were coated layer-by-layer (LbL) on AM50 coupons using a facile single-step air jet spinning (AJS) approach. The corrosion performance of coated and uncoated coupon samples was investigated by means of electrochemical measurements.

A biocompatible coating consists of a poly(vinyl acetate)/hydroxyapatite (PVAc/HA) composite nanofiber mat was applied to NaOH-treated titanium metal by means of a novel, facile and efficient air jet spinning (AJS) approach. Results showed that HA nanoparticles (NPs) strongly embedded onto the AJS single fiber surface resulting in a strong chemical interfacial bonding between the two phases due to the difference in kinetic energies. It was proven that AJS membrane coatings can provide significant improvement in the corrosion resistance of titanium substrate.

Aedes aegypti and Aedes albopictus Habitat Preferences in South Texas, USA.

Environ Health Insights

December 2014

University of Texas Pan - American, Department of Biology, 1201 West University Dr., Edinburg, Texas, USA.

The South Texas region has a historical record of occasional dengue outbreaks. The recent introduction of chikungunya virus to the Caribbean suggests that this disease may be a concern as well. Six different cities and three field habitat types (residential, tire shops, and cemeteries) were examined for evidence of habitat and longitudinal preference of two vector species, Aedes aegypti and Aedes albopictus.

How are false memories distinguishable from true memories in the Deese-Roediger-McDermott paradigm? A review of the findings.

Psychol Res

Department of Psychology, University of Texas-Pan American, 1201 West University Dr, Edinburg, TX, 78539-2999, USA,

This article reviewed the literature comparing true and false memories. Although false memory experience is typically characterized as compellingly similar to true memory experience, research also indicates many distinctions between these two types of memory. The primary focus of this article was on comparing these two types of memory in the Deese-Roediger-McDermott paradigm on a number of independent and dependent measures.

Department of Psychology, University of Texas–Pan American, 1201 West University Dr., Edinburg, TX 78539-2999, USA.

This study investigated whether the encoding and retrieval of plurality information and letter-case information of words in recognition memory can be inhibited. Response-deadline experiments (Hintzman & Curran, 1994) using single words have indicted a controlled processing mode, whereas studies using meaningful sentences (e.g.

Conscious and unconscious discriminations between true and false memories.

Conscious Cogn

September 2011

Department of Psychology & Anthropology, University of Texas-Pan American, 1201 West University Dr., Edinburg, TX 78539-2999, USA.

When subjects give higher confidence or memory ratings to a test word in a recognition test, do they simply raise their criterion without making better discrimination, or do they raise both criterion and true discrimination between the studied words (SW) and the lures? Given that previous studies found subjects' false alarm responses to lures slower than to SW, and recognition latency inversely correlated with the confidence rating, can the latency difference between the lures and SW be accounted for by confidence or memory ratings? The present results showed that when subjects gave higher confidence or memory ratings, both their bias and sensitivity were raised, indicating that they could consciously distinguish the lures from the SW. However, a latency difference between true and false recognitions persisted after confidence and memory ratings were held constant, suggesting an unconscious source of discrimination between the two types of memory.
