COVID-19 Living Overview of Evidence repository is highly comprehensive and can be used as a single source for COVID-19 studies.

Background And Objective: The coronavirus disease 2019 Living OVerview of Evidence (COVID-19 L·OVE) is a public repository and classification platform for COVID-19 articles. The repository contains more than 430,000 articles as of September 20, 2021 and intends to provide a one-stop shop for COVID-19 evidence. Considering that systematic reviews conduct high-quality searches, this study assesses the comprehensiveness and currency of the repository against the total number of studies in a representative sample of COVID-19 systematic reviews.

Millimeter-Scale Zn(3-ptz) Metal-Organic Framework Single Crystals: Self-Assembly Mechanism and Growth Kinetics.

The solvothermal synthesis of metal-organic frameworks (MOFs) often proceeds through competing crystallization pathways, and only partial control over the crystal nucleation and growth rates is possible. It challenges the use of MOFs as functional devices in free-space optics, where bulk single crystals of millimeter dimensions and high optical quality are needed. We develop a synthetic protocol to control the solvothermal growth of the MOF [Zn(3-ptz)] (MIRO-101), to obtain large single crystals with projected surface areas of up to 25 mm in 24 h, in a single reaction with in situ ligand formation.
