The optimization of nonradiative recombination losses through interface engineering is key to the development of efficient, stable, and hysteresis-free perovskite solar cells (PSCs). In this study, for the first time in solar cell technology, we present a novel approach to interface modification by employing one-dimensional lepidocrocite (henceforth referred to as 1DL) TiO-based nanofilaments, NFs, between the mesoporous TiO (mp TiO) and halide perovskite film in PSCs to improve both the efficiency and stability of the devices. The 1DLs can be easily produced on the kilogram scale starting with cheap and earth-abundant precursor powders, such as TiC, TiN, TiB, etc.

Laminating a free-standing carbon electrode film onto perovskite film is a promising method for fabricating HTM (hole transport material)-free carbon electrode perovskite solar cells (c-PSCs), offering more flexibility by decoupling the processes of carbon electrode and perovskite layer formation. However, the power conversion efficiency (PCE) of laminated HTM-free c-PSCs (<16.5 %) remains lower compared to c-PSCs with printed carbon pastes (>20 %), primarily due to poor interfacial contact between the perovskite and carbon layers.

Jt Comm J Qual Patient Saf
February 2025
Background: The coronavirus disease 2019 (COVID-19) pandemic affected quality improvement work that was key to hospital-acquired infection (HAI) prevention efforts for many hospitals. Central line-associated bloodstream infection (CLABSI) standardized infection ratios (SIRs) were highly affected by the pandemic.
Methods: After seeing an increase in CLABSI SIRs through early 2021, a health care system including 12 acute care hospitals in the midwestern United States focused on processes and process measures for CLABSI prevention.
Development of a City-wide Rapid Antiretroviral Therapy Initiation Toolkit for People Newly Diagnosed With HIV in the Southern United States.
Open Forum Infect Dis
December 2024
Department of Medicine, Vanderbilt University Medical Center, Nashville, Tennessee, USA.
Background: Rapid antiretroviral therapy (ART) initiation, in which individuals with HIV start treatment within days of diagnosis, is a key component of the United States (US) Ending the HIV Epidemic initiative. The Memphis Metropolitan Statistical Area ranks second in the US for HIV incidence, yet only ∼60% of individuals link to treatment within 1 month of diagnosis. This study aimed to identify barriers and strategies for implementing rapid ART initiation in Memphis.

Duke University, School of Medicine, Department of Medicine, Durham, NC, USA.
Background: eSource software that transfers patient electronic health record data into a clinical trial electronic case report form holds promise for increasing data quality while reducing data collection, monitoring and source document verification costs. Integrating eSource into multicenter clinical trial start-up procedures could facilitate the use of eSource technologies in clinical trials.
Methods: We conducted a qualitative integrative analysis to identify eSource site start-up key steps, challenges that might occur in executing those steps, and potential solutions to those challenges.
