Exploring the COVID-19 Landscape and Our Path Forward Using a Formalized SWOT Analysis.

Objective: This study aimed to share the results of a formalized SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis focusing on perceptions and the long-term impact of the COVID-19 pandemic.

Methods: The study used a parallel mixed-methods approach. This included a quantitative component, which used presurvey descriptive data, and a qualitative component, which involved SWOT analysis via focus groups.

Investigating the association of acute kidney injury (AKI) with COVID-19 mortality using data-mining scheme.

COVID-19 has caused significant challenges in kidney research and disease management. Data mining techniques such as logistic regression (LR) and decision tree (DT) were used to model data. All analyses were performed using SPSS 25 and Python 3.

Building an Iron Chromophore Incorporating Prussian Blue Analogue for Photoelectrochemical Water Oxidation.

Invited for the cover of this issue is the Ferdi Karadas and Ekmel Ozbay groups at Bilkent University and co-workers. The image presents an utopic city in Iron Age, which is powered by an iron photosensitizer that bridges semiconductor buildings (TiO nanowires) and the catalyst (cobalt site).

Building an Iron Chromophore Incorporating Prussian Blue Analogue for Photoelectrochemical Water Oxidation.

The replacement of traditional ruthenium-based photosensitizers with low-cost and abundant iron analogs is a key step for the advancement of scalable and sustainable dye-sensitized water splitting cells. In this proof-of-concept study, a pyridinium ligand coordinated pentacyanoferrate(II) chromophore is used to construct a cyanide-based CoFe extended bulk framework, in which the iron photosensitizer units are connected to cobalt water oxidation catalytic sites through cyanide linkers. The iron-sensitized photoanode exhibits exceptional stability for at least 5 h at pH 7 and features its photosensitizing ability with an incident photon-to-current conversion capacity up to 500 nm with nanosecond scale excited state lifetime.

Strong Light-Matter Interactions in Au Plasmonic Nanoantennas Coupled with Prussian Blue Catalyst on BiVO for Photoelectrochemical Water Splitting.

Invited for this month's cover is the group of Ferdi Karadas and Ekmel Ozbay at Bilkent University. The image proposes a hybrid architecture, in which the semiconductor photoactive host is coupled to a plasmonic particle and a catalyst, to significantly substantiate the photoactivity of the cell. The Full Paper itself is available at 10.

Strong Light-Matter Interactions in Au Plasmonic Nanoantennas Coupled with Prussian Blue Catalyst on BiVO for Photoelectrochemical Water Splitting.

A facial and large-scale compatible fabrication route is established, affording a high-performance heterogeneous plasmonic-based photoelectrode for water oxidation that incorporates a CoFe-Prussian blue analog (PBA) structure as the water oxidation catalytic center. For this purpose, an angled deposition of gold (Au) was used to selectively coat the tips of the bismuth vanadate (BiVO ) nanostructures, yielding Au-capped BiVO (Au-BiVO ). The formation of multiple size/dimension Au capping islands provides strong light-matter interactions at nanoscale dimensions.

Angstrom Thick ZnO Passivation Layer to Improve the Photoelectrochemical Water Splitting Performance of a TiO Nanowire Photoanode: The Role of Deposition Temperature.

In this paper, we demonstrate that angstrom thick single atomic layer deposited (ALD) ZnO passivation can significantly improve the photoelectrochemical (PEC) activity of hydrothermally grown TiO NWs. It is found that this ultrathin ZnO coating can passivate the TiO surface defect states without hampering the carrier's transfer dynamics. Moreover, a substantial improvement can be acquired by changing the deposition temperature of the ZnO layer (80 °C, and 250 °C) and named as 80 °C TiO-ZnO, and 250 °C TiO-ZnO.
