Mechanical property enhancement of self-bonded natural fiber material via controlling cell wall plasticity and structure
This article explores self-bonded natural fiber material (SNFM) as a promising alternative for plastic and wood owing to its abundant raw material resources and low environmental impact. In this study, a high-performance SNFM was developed by the comprehensive treatments for the plasticity and structure of fiber cell walls. The self-bonded mechanism for natural fiber materials was also discussed. The SNFM products showed excellent mechanical performance, which was superior to that of natural wood and plastic.

Electrical and Thermal Conductivity of Polylactic Acid (PLA)-Based Biocomposites by Incorporation of Nano-Graphite Fabricated with Fused Deposition Modeling
This article describes a study to improve the electrical and thermal conductivity of the polylactic acid/wood flour/thermoplastic polyurethane composites by Fused Deposition Modeling (FDM). The results showed that, when the addition amount of nano-graphite reached 25 pbw, the volume resistivity of the composites decreased to 10⁸ Ω·m, which was a significant reduction, indicating that the conductive network was already formed. It also had good thermal conductivity, mechanical properties, and thermal stability.

Monitoring Usage of Open Access Long-Form Content
Presentation for NISO Virtual Conference "Long Form Content: Ebooks, Print Volumes and the Concerns of Those Who Use Both." The Andrew W. Mellon Foundation recently funded a study of the landscape of usage data for open-access scholarly monographs and an investigation of the viability of creating a data trust for sharing of usage data among stakeholders in the publishing ecosystem. In spring 2019, the Book Industry Study Group (BISG) will publish a final white paper that takes into account feedback from the community during a consultation period. This presentation, part of a NISO virtual conference (https://www.niso.org/events/2019/03/long-form-content-ebooks-print-volumes-and-concerns-those-who-use-both ), provides a summary of the main findings and proposals of the forthcoming white paper.

Multimodal switching of a redox-active macrocycle
This article looks at molecules that can exist in multiple states with the possibility of toggling between those states based on different stimuli. They have potential for use in molecular switching or sensing applications. The coupling of two different oxidation states with two different charge-transfer states within one macrocyclic scaffold delivers up to five different optical outputs. This molecular switching manifold exploits intramolecular coupling of multiple redox active substituents within a single molecule.

The membrane pacemaker hypothesis: novel tests during the ontogeny of endothermy
Article explores the ‘membrane pacemaker’ hypothesis which proposes a biochemical explanation for among-species variation in resting metabolism, based on the positive correlation between membrane docosahexaenoic acid (DHA) and metabolic rate. The authors tested this hypothesis using a novel model, altricial red-winged blackbird nestlings, predicting that the proportion of DHA in muscle and liver membranes should increase with the increasing metabolic rate of the nestling as it develops endothermy. In support of the membrane pacemaker hypothesis, DHA proportions increased in membranes from pectoralis muscle, muscle mitochondria and liver during post-hatch development. By contrast, elevated dietary DHA had no effect on resting metabolic rate, despite causing significant changes to membrane lipid composition.

Haints & Haunts: Spiritual Correspondence in Harrow County
This presentation was delivered as part of a panel on "Comics and the Epistolary Tradition" at the 2018. Popular Culture Association National Conference. The panel was sponsored by the Comics & Comic Art section of the PCA. It discusses the theme of "correspondence" in the comic series Harrow County, considering the term as part of its narrative and supplementary content, including letters from readers. It argue that the comic creates a shared community of artists, readers, and characters to confront issues of trauma, memory, and childhood.

Rate Coefficient Measurements and Theoretical Analysis of the OH + (E)‑CF₃CH==CHCF₃ Reaction
Rate coefficients, k, for the gas-phase reaction of the OH radical with (E)CF3CHCHCF3 ((E)-1,1,1,4,4,4-hexafluoro-2-butene, HFO-1336mzz(E)) were measured over a range of temperatures (211−374 K) and bath gas pressures (20−300 Torr; He, N2) using a pulsed laser photolysis−laser-induced fluorescence (PLP−LIF) technique. k1(T) was independent of pressure over this range of conditions with k1(296 K) = (1.31 ± 0.15) × 10−13 cm3 molecule−1 s−1 and k1(T) = (6.94 ± 0.80) × 10−13exp[−(496 ± 10)/T] cm 3 molecule−1 s−1, where the uncertainties are 2σ, and the pre-exponential term includes estimated systematic error. Rate coefficients for the OD reaction were also determined over a range of temperatures (262−374 K) at 100 Torr (He). The OD rate coefficients were ∼15% greater than the OH values and showed similar temperature dependent behavior with k2(T) = (7.52 ± 0.44) × 10−13exp[−(476 ± 20)/T] and k2(296 K) = (1.53 ± 0.15) × 10−13 cm3 molecule−1 s−1. The rate coefficients for reaction 1 were also measured using a relative rate technique between 296 and 375 K with k1(296 K) measured to be (1.22 ± 0.1) × 10−13 cm3 molecule−1 s−1, in agreement with the PLP−LIF results. In addition, the 296 K rate coefficient for the O3 +( E)CF3CHCHCF3 reaction …
