Reducing delamination of an electron-transporting polymer from a metal oxide for electrochemical applications.

Delamination of the electron-transporting polymer N2200 from indium tin oxide (ITO) in aqueous electrolytes is mitigated by modifying ITO with an azide-functionalized phosphonic acid (PA) which, upon UV irradiation, reacts with the polymer. The optical, electrochemical, and spectroelectrochemical properties of N2200 thin films are retained in aqueous and non-aqueous media.

Maximizing Vanadium Deployment in Redox Flow Batteries Through Chelation.

By tailoring the coordination sphere of vanadium to accommodate a 7-coordinate geometry, a highly soluble (>1.3 M) and reducing (-1.2 V vs Ag/AgCl) flow battery electrolyte is generated from [V(DTPA)] (DTPA = diethylenetriaminepentaacetate).

Use and misuse of opioid after gynecologic surgery.

Postoperative opioid use following gynecologic surgery may be necessary for effective treatment of pain; however, it can result in significant side effects, adverse reactions, and negative health consequences, including prolonged problematic use. Surgeons and healthcare providers of patients recovering from gynecologic procedures should be aware of effective strategies that can decrease the need for opioid use, while providing high-quality pain management. These include adherence to Enhanced Recovery After Surgery Protocols, particularly the use of multimodal analgesia management.

1,4,5,8-Naphthalene tetracarboxylate dianhydride/g-CN van der Waals heterojunctions exhibit enhanced photochemical HO production and antimicrobial activity.

Organic semiconductors, including graphitic carbon nitride (g-CN, CN), represent an important class of materials for the development of novel antimicrobial or biomedical technologies. Of principal interest is the ability of these materials to catalyze the reduction of elemental oxygen to generate reactive oxygen species (ROS), including hydrogen peroxide (HO). Here, we describe the fabrication of photoactive van der Waals heterojunctions incorporating 1,4,5,8-naphthalene tetracarboxylic dianhydride (NTCDA) and CN.

Examining the population level and individual level longitudinal stability of psychosocial measures in the US Army's Global Assessment Tool (GAT).

As a component of the US Army's Comprehensive Soldier and Family Fitness program (CSF2), the Global Assessment Tool (GAT) represents a multidimensional constellation of measures designed to assess characteristics related to resilience. Using a foundation of validated measures from prior research, the GAT has been the vehicle for self-assessment to provide Soldiers, their families, and Army Civilians snapshots of their psychosocial wellness. Despite the long history of the measurement instrument (first implemented in 2009) and widespread use (mandatory for all active-duty Soldiers annually), the longitudinal capabilities of the GAT has received little attention.

Development of Photoactive -CN/Poly(vinyl alcohol) Composite Hydrogel Films with Antimicrobial and Antibiofilm Activity.

Free-standing, composite hydrogels containing the visible-light responsive metal-free semiconductor graphitic carbon nitride (-CN) as an integral component have been fabricated by direct casting techniques. At 0.67% -CN loading, intermolecular interactions between the semiconductor particles and the PVA polymer chains enhance both the mechanical and photophysical properties of the resulting hydrogels.

SOLLID - a single centre study to develop methods to investigate the effects of low radiation doses within nuclear medicine, to enable multicentre epidemiological investigations.

There is continuing debate concerning the risks of secondary malignancies from low levels of radiation exposure. The current model used for radiation protection is predicated on the assumption that even very low levels of exposure may entail risk. This has profound implications for medical procedures involving ionising radiation as radiation doses must be carefully monitored, and for diagnostic procedures are minimised as far as possible.
