Low-Cost Reliable Corrosion Sensors Using ZnO-PVDF Nanocomposite Textiles
This article investigates the reliability and effectiveness of nonwoven zinc(II) oxide-polyvinylidene fluoride (ZnO-PVDF) nanocomposite fiber textiles as an embedded corrosion sensor using an accelerated thermal cyclic method paired to electrochemical impedance spectroscopy (EIS). Results suggest that the flexible sensor is reliable at both monitoring the corrosion and acting as a corrosion barrier.

Effect of amorphous cellulose on the deformation behavior of cellulose composites: molecular dynamics simulation
This article is a study aimed at predicting and enhancing the properties of the blend, as well as exploring the mechanism, of a polylactic acid (PLA)/amorphous cellulose composite system through molecular characterization. The static properties of the amorphous cellulose/PLA blend model and the mechanical response of the material under uniaxial tension were studied by molecular dynamics simulation to establish the structure–property relationship.

Early Oxidative Transformations During the Biosynthesis of Terrein and Related Natural Products
This article combines heterologous expression and in vitro studies to show that the flavin-dependent monooxygenase (FMO) TerC catalyzes the initial oxidative decarboxylation of 6-HM. The results demonstrate that the biosynthetic pathways of terrein and related(polychlorinated) congeners diverge after oxidative decarboxylation of the lactone precursor that is catalyzed by a conserved FMO and further indicate that early dehydration of the side chain is an essential step.

Approaching Bounded Rationality: From Quantum Probability to Criticality
This article discusses the decision-making model (DMM), a paradigmatic instance of criticality, which deals with bounded rationality issues in a similar way as quantum probability (QP), generating choices that cannot be accounted by classical probability (CP). This work may contribute to considering criticality as another possible fundamental pillar in order to improve the understanding of cognition and of quantum mechanics.

A Bayesian Rate Ratio Effect Size to Quantify Intervention Effects for Count Data in Single Case Experimental Research
This article formulates a within-subject Bayesian rate ratio effect size (BRR) for autocorrelated count data that would obviate the need for small sample corrections. The authors illustrate this within-subject effect size using real data for an ABAB design and provide codes for practitioners who may want to compute BRR.

First principles computation of composition dependent elastic constants of omega in titanium alloys: implications on mechanical behavior
Article on the poor mechanical properties of Ti alloys. The study shows that the elastic properties of the ω-phase can be systematically varied as a function of its composition to enhance both the ductility and strength of the Ti-alloy. Furthermore, that ω precipitates are not intrinsically embrittling and detrimental and that Ti-alloys can be created with both good ductility and strength by tailoring ω precipitates' composition instead of completely eliminating them.

Formulating a Scalable Approach to Patron-Requested Digitization in Archives
This article examines how archives were forced to rethink their modes of providing access to physical collections because of the coronavirus of 2019 (COVID-19). Whereas difficult copyright questions raised by reproducing items could previously be skirted by requiring researchers to work with materials in person, the long-term closure of reading rooms and decrease in long-distance travel mean that archives need a workflow for handling user digitization requests that is scalable and requires consulting only easily identifiable information and, assuming full reproduction is off the table, reproducing items in a collection under 17 U.S.C. § 108 or through a strategy of rapid risk assessment. There is a challenge in creating a policy that will work across different formats and genres of archival materials, so this article offers some suggestions for how to think about these parameters according to US copyright law and calls for a committee of experts to work out a model policy that could serve remote users of archival collections even after the COVID-19 crisis has passed.

3D-printed and injection molded polymer matrix composites with 2D layered materials
This article reports on a study where 2D TMDs (MoS₂ and WS₂) and the 3D allotrope of carbon and graphite were incorporated into acrylonitrile butadiene styrene (ABS) and polyethylene terephthalate glycol (PETG) matrices in order to form polymer matrix composites (PMCs). The multipronged analysis described in this study was motivated by the purpose to fuse together topics of low-cost, additive manufacturing with 2D layered materials, and studying their ensuing mechanical and tribological properties.
