Portraits of clinicians quickly became emblematic of what the COVID-19 pandemic has demanded of everyone, especially caregivers who witnessed deaths likely unprecedented in number during their careers. This article describes an arts-based research protocol exploring portraiture as a medium for representing and understanding clinicians' experiences, mostly during the first year of the pandemic. This article presents , a large oil on canvas portrait commissioned by the to commemorate the American Medical Association's 175th year. The article also includes , a charcoal study drawing for that portrait, and , a 3 by 3 collection of 9 smaller oil on canvas portraits.

The degummed wastewater from silk processing contains a huge amount of amino acids and polypeptides from sericin. The silk degumming water is far from being exploited fully. Sericin in the degumming water is generally wasted and causes environmental pollution.

Water pollution seriously affects the development of society and human life. There are various kinds of pollutants, including soluble pollutants and insoluble floaters on the water surface. Herein, the photocatalyst semiconductor BiOCl and superhydrophobic functional particles Mg(OH) were deposited on the surfaces of canvas and polyester felt to construct superhydrophobic canvas and polyester felt.

Fungi are important contaminants of historic canvas paintings worldwide. They can grow on both sides of the canvas and decompose various components of the paintings. They excrete pigments and acids that change the visual appearance of the paintings and weaken their structure, leading to flaking and cracking.

This study starts from the need to remove a mix of proteins, oils and natural resin, called in the Italian literature, from the back of canvas paintings. The aim of this study is to develop and evaluate the effectiveness of two different agarose/enzyme gels containing, respectively, a trypsin derived from porcine pancreas and a lipase from , both in an aqueous solution of deoxycholic acid-triethanolamine soap. Enzymes were selected because of their action on peptide and ester bonds, effectiveness at maintaining a weak alkaline pH and low cost.

We describe a new, safe, and effective method for removing wax resin adhesive from the canvases of paintings conserved by the once widely used Dutch Method, which involved attaching a new canvas to the back of a painting using an adhesive made of beeswax and natural resin. First, a low-toxicity cleaning mixture for dissolving the adhesive and removing it from the canvases was developed, and then a nanocomposited organogel was obtained. The ability of the organogel to remove the adhesive from canvases was investigated on the lining of the 1878 painting "Battle of Grunwald" by Jan Matejko, with promising results.
