Surface cleaning of 2D materials : Boron Nitride Nanosheets (BNNS) and exfoliated Graphite Nanoplatelets (GNP)

Surface impurities such as water and surfactants can significantly affect the properties of 2D materials. They disrupt the 2D material lattice structure and surface chemistry and also promote electron and phonon scattering. Strategies to clean the surfaces of 2D materials are therefore critical to achieving optimal properties. Boron nitride nanosheets (BNNS) and exfoliated graphite nanoplatelets (GNP) are treated using three procedures: washing with ethanol, water‐assisted freeze‐drying, and freeze‐drying without addition of water in an attempt to remove two impurities—water and an ionic surfactant (sodium cholate, SC). There is total removal of water from BNNS when the starting material is treated using either freeze drying method whereas some water (≈40%) and traces of ethanol are detected in BNNS when washed with ethanol. It is not possible to exclude the presence of SC on BNNS and GNP post treatment; however, the relatively high amount of sodium (from SC) in the samples after freeze‐drying suggests the process contributed to the separation of BNNS and GNP aggregates. The BNNS flakes separate when washed with ethanol or freeze‐dried in the absence of water. The crystalline structure of BNNS and GNP is retained post treatments. This approach provides a route to cleaning and separating 2D materials

Fused deposition modelling (FDM) of composites of graphene nanoplatelets and polymers for high thermal conductivity : a mini-review

Composites of polymers and the graphene family of 2D materials continue to attract great interest due their potential to dissipate heat, thus extending the in-service life of electronic and other devices. Such composites can be 3D printed using Fused Deposition Modelling into complex bespoke structures having enhanced properties, including thermal conductivity in different directions. While there are controversial opinions on the limitations of FDM for large-scale and high volume production (e.g. long production times, and expensive printers required), FDM is an innovative solution to the manufacture of small objects where effective thermal management is required and it is a valid alternative for the manufacture of (micro)-electronic components. There are few papers published on the FDM of functional composite materials based on graphene(s). In this mini-review, we describe the many technical challenges that remain to successful printing of these composites by FDM, including orientation effects, void formation, printing and feeding rates, nozzle and printing bed temperatures and the role each has in determining the thermal conductivity of any composite product made by FDM. We also compare these initial reports with those on FDM of other and related carbonaceous fillers, such as multi-walled carbon nanotubes and carbon fibre

2D boron nitride nanosheets (BNNS) prepared by high-pressure homogenisation : structure and morphology

2D Boron Nitride Nano-sheets (BNNS) were prepared using a high-pressure homogenisation process to exfoliate bulk hexagonal boron nitride (h-BN). The effectiveness of this process was studied by characterising bulk h-BN and BNNS post-processing using numerous techniques. The BNNS produced was composed of a mixture of sheets having lengths on the nanometre (nm) scale, but lateral thicknesses on the micron (μm) length scale. The product was a macro-porous material containing slit-like pores with a surface area of 170 m2 g−1. It had a polycrystalline structure with d002 = 0.335 nm and L002 = 2 nm. From the sharp E2g peak in the Raman spectrum at 1360 cm−1 (FWHM = 12.5 cm−1), the sheets had a low defect density and were highly exfoliated. X-Ray photoelectron spectroscopy (XPS) studies detected B–OH and N–H groups on the BNNS surface and the presence of residual surfactant. Contact angle measurements (60° ± 3° (0 s); 40° ± 2° (10 s)) confirmed a hydrophilic surface. The BNNS was thermally stable under oxidative conditions up to 323 °C

Addressing cervical cancer disparities in Texas: Expansion of a community-based prevention initiative for medically underserved populations

Although cervical cancer is preventable, significant disparities exist in access to screening and prevention services. In medically underserved areas (MUAs) of Texas, these rates are 55% higher compared to the remainder of the US. In 2019, we expanded a multicomponent, comprehensive program to improve cervical cancer prevention in partnership with 13 clinics and mobile vans in MUAs of Texas. Our multicomponent intervention program consists of community education and patient navigation coupled with a training/mentoring program for local medical providers to perform diagnostic procedures and treatment for patients with abnormal screening results. Hands-on training courses to learn these skills are coupled with biweekly telementoring conferences using Project ECHO® (Extension for Community Healthcare Outcomes). This program was implemented in 2015 and expanded to other MUAs in Texas in 2019. From March 2019 to August 2022, 75,842 individuals were educated about cervical cancer screening and HPV vaccination. A total of 44,781 women underwent screening for cervical cancer, and 2,216 underwent colposcopy and 264 underwent LEEP. High-grade cervical dysplasia was diagnosed in 658 individuals and invasive cervical cancer in 33 individuals. We trained 22 providers to perform colposcopy and/or LEEP. In addition, 78 Project ECHO telementoring sessions were held with an average of 42 attendees per session, with 72 individual patient cases discussed. Our comprehensive community-based prevention initiative for medically underserved populations has led to a significant number of individuals undergoing cervical cancer screening in MUAs, as well as improved access to colposcopy and LEEP services

Comportamiento agroindustrial de cuatro variedades de arroz (Oriza sativa, l) cultivadas en suelo salino y no salino en la Unidad Empresarial de Base “La Gabina” (Original)

The work was developed in areas to the UEB La Gabina, belonging to the Agroindustry Company of Grains Fernando Echenique (EAIG), in 8 lots, with soil saline (four)and not saline (four), in the campaign of cold 2019-2020, with the objective of evaluating the industry behavior of four varieties cultivated in saline and not saline soil.

Skunk River Review 2010-11, vol 23

Welcome to the 2010-2011 edition of The Skunk River Review! As the new editor of this publication, I was excited to see the number of submissions and the overwhelming enthusiasm of the students. This year\u27s publication includes work from Composition I, Composition II, Literature, and College Resources courses. Whereas The Skunk River Review is academic work that begins in the classroom, it also reflects student\u27s interests. The essays are not edited for MLA format or general errors because the publication is used as a teaching tool in many classrooms.https://openspace.dmacc.edu/skunkriver/1002/thumbnail.jp
