“You Need to Make it as Easy as Possible for Me”: Creating Scholarly Communication Reports for Liaison Librarians
Authors: Lange Jessica , Hanson Carrie 
Published: May 2020

INTRODUCTION The typical trifecta of liaison librarian positions (collections, reference, and teaching) is shifting to include additional skillsets and competencies, particularly scholarly communications. While liaison librarians adapt to these changing roles, the question of how to upskill and train liaison librarians in scholarly communications is timely and still in flux. The lack of time required to improve these competencies and skills is an oft-cited challenge. DESCRIPTION OF PROJECT To address the challenge of lack of time, this article describes a pilot project undertaken with the aid of a Master of Information Studies practicum student to create scholarly communications reports for liaison librarians. These reports provide background knowledge and discipline-specific information about the scholarly communications landscape, particularly within the institutional context. The goal of the reports is to provide liaison librarians with greater contextual knowledge of their disciplines and the publishing patterns within their departments. This article will discuss the methodology behind creating these reports as well as feedback from liaison librarians on their relevance and potential use. NEXT STEPS The initial pilot was promising, however using a practicum student to create such reports may not be sustainable. Other possibilities include holding “research report retreats” for liaisonlibrarians to complete their own reports with a scholarly communications expert on hand. Additionally, institutions without a master’s program in library and information studies could consider the creation and updating of such reports as a backup project for existing fulltime or student staff.

Aims: The study is intended to compare the freshly collected henna (Lawsonia inermis L.) and the market henna in term of microscopical key elements and heavy metals contamination. Moreover, this study is aimed to investigate the effect of henna and its oily additives on kidney histology in female mice.
Study Design: Department of Pharmacognosy, Faculty of Pharmacy, University of Tripoli and Animals House, Biotechnology Research Center in 2010.
Methodology: The powders of collected and market henna have been subjected to a microscopical study with magnification of 5x then 40 x to investigate the henna key elements, which are calcium oxalate clusters, anomocytic stomata, starch grains and fibers. Three elements: arsenic (As), mercury (Hg) and lead (Pd) were analyzed by atomic absorption spectroscopy (AAs) for the collected and market henna. For histopathological study, an aqueous extracts of L. inermis leaves and L. inermis leaves-oils were prepared by maceration. Eighteen female Albino Wister mice (3-4-months, 20-25 gm) were injected with the prepared extracts subcutaneously by dose 50 ml/kg/day for 5 days. Kidneys were collected and subjected to histopathological study.
Results: From this study, the microscopical investigation exhibited the presence of some elements which are never mentioned as the henna key elements. Both market and collected henna were contaminated with a high level of heavy metals specially lead (Pd). The histopathological findings implied that there are many histological changes on the kidney tissues such as aggregation of round cells and congestion of blood vessels.
Conclusion: The market henna might be adulterated with other types of plant. The presence of a high concentration of lead (Pd) in the collected henna as well as the market henna might be considered as the cause of some L. inermis adverse effects. L. inermis leaves and L. inermis leaves-oils aqueous extracts implied many abnormalities in the kidney tissues.

Published: May 2020

Background: The world is now in an emergency of preventing the drastic spread of COVID-19. After the infection was first reported in December 2019, almost every country did not pay attention to this highly contaminated disease and failed to react swiftly. Now the whole planet is in an vulnerable state, resulting to increase the mortality rate and facing difficulties in all socio-economic aspects. That is why we have the urge to develop an efficient mathematical model (quarantine) based on social consciousness to control the epidemic.
Methods: This is a quarantine mathematical model. The outcome of the system is dependent on social consciousness. We have calculated the awareness level by considering various socio-economic factor of each country. In our model, the parameters are Education Index, Gross Domestic Product (GDP) per capita, population density, high literacy and stable economy. To maximize the efficiency of the model, it has to be implemented in initial stage. However, strictapplication of the method in vigorous stage of epidemic will also bring a satisfactory outcome.
Results: In Spain, quarantine was effected on March 14, 2020. Spain experienced an increase in reported cases for 13 days of quarantine enforcement and from the 14th day, daily reported cases started to decrease with small fluctuation. Government ensured the social isolation through quarantine. After imposition of a quarantine on March 9, 2020 in Italy, within 13 days of lock-down, the maximum number of infection started to decrease. Similar results observed in France. Higher social consciousness would decrease the number of infected population dramatically while minimal or lower awareness will do a outburst.
Conclusion: Outbreak will be in control of health care system which yields to reduce the death rate and will ensure social and economic stability.

Published: May 2020

Aims: To determine the toxic effect of refinery industrial effluents using three toxicity bioassays.
Study Design: Five treatments and the controls designs were set up in triplicates containing 6.25%,12.5%, 25%, 50%, 100% and 0% of the industrial effluents and incubated at 24°C for 0 - 96 h. The five treatments and control set ups designated as PH, Warri and Control (Without effluent) were used to determine the toxic effect of industrial effluents.
Place and Duration of Study: Department of Microbiology, Faculty of Natural Sciences, Chukwuemeka Odumegwu Ojukwu University, Uli Nigeria between September, 2019 and December, 2019.
Methodology: A laboratory scale study was carried on two composite samples of the produced water samples from the two studied areas using physicochemical analyses, microalgal toxicity test, mollusk toxicity and Zea mays test.
Results: The results revealed that Port Harcourt refinery effluent contains higher quantities of physicochemical parameters than the Warri effluent sample. Warri sample had the most harmful effects on Selenastrum capricornutum, Lymnaea stagnalis and Zea mays, with ErC50 values of 47.62%, LC50 of 51.86% and EC50 of-32.68%, respectively. Inhibition (%) and mortality (%) of all species used were found to be concentration dependent with a significant (P < 0.05) strong positive correlation at increasing concentrations of industrial effluents.
Conclusion: Thus, these raw industrial effluents from Port Harcourt and Warri refineries are toxic and induced growth inhibition, mortality and phytotoxicity and adequate measures should be taken by these industries to minimize their negative environmental impacts.
Nucleus‐to‐Plastid Phytochrome Signalling in Controlling Chloroplast Biogenesis
Authors: Yoo Chan Yul , Han Soeun , Chen Meng 
Published: May 2020

Abstract
The biogenesis of photosynthetically active chloroplasts in flowering plants (angiosperms) is initiated by light through the red and far‐red photoreceptors, phytochromes, which activate photosynthesis‐associated genes encoded by both the nuclear and plastid genomes. Because photoactivated phytochromes localize to the nucleus but not the plastids, phytochromes ought to control plastid transcription through nucleus‐to‐plastid or anterograde signalling. However, the mechanism of anterograde signalling remains poorly understood. Recent advances in our understanding of phytochrome signalling and plastid transcription led to the discovery of the framework of an anterograde signalling pathway, which links light‐dependent regulation of nuclear repressors of chloroplast biogenesis to the control of the assembly and activity of the bacterial‐type plastidial RNA polymerase for transcribing plastid‐encoded photosynthesis genes.
This article is aimed to gather and reanalyze the evidence in the literature relevant to the phytochrome control of chloroplast biogenesis to forge a model of anterograde signalling mechanisms for the regulation of plastid transcription by light.

Published: May 2020

AbstractBone marrow (BM) organoids provide powerful tools to study the vital interplay between the BM microenvironment and resident cells. Current biomaterials, however, are limited in terms of versatility for independently studying the biochemical and biophysical properties that regulate BM function. Here, a transglutaminase (TG) crosslinked system that seamlessly incorporates poly(ethylene glycol) (PEG) and hyaluronic acid (HA) into hybrid hydrogels for the formation of BM analogues is presented. By combining features of PEG and HA, these novel biomaterials are tunable to optimize their physical and biological properties for BM organoid formation. Utility of the TG‐PEG/HA hybrid hydrogels to maintain, expand, or differentiate human bone marrow‐derived stromal cells and human hematopoietic stem and progenitor cells in vitro is demonstrated. Even more compelling, TG‐PEG/HA hybrid hydrogels are superior to currently used natural biomaterials in forming humanized BM organoids in a xenograft model. Hybrid hydrogels in comparison to pure PEG or pure HA afford the ideal attributes of both regarding material handling, structural integrity, and minimizing macrophage infiltration in vivo. The engineered humanized BM organoids presented here may be effective tools for the study of this intricate organ.
3D Printed Meta‐Helmet for Wide‐Angle Thermal Camouflages

Published: May 2020

AbstractThermal camouflage utilizes the manipulation of heat fluxes to conceal an arbitrary object in various environments from being detected via thermography. In the past decade, the field of thermal metamaterials and the technique of 3D printing have been rapidly developed, which makes nonintuitive heat flux manipulation feasible. However, when thermal metamaterials are applied to the thermal camouflaging, their conductivities are dependent on the properties of background, leading to the damage of background integrality. Moreover, previous thermal camouflaging schemes have mostly worked in the 2D regime, largely restricting their functional angles and application scenarios, especially in complex environments. Here, wide‐angle radiative thermal camouflaging is realized by using a 3D‐printed meta‐helmet of extremely anisotropic thermal conductivities. Based on 3D coordinate transformation, this meta‐helmet directly maps temperature distributions from the background to the metamaterial surface without damaging background integrity. The non‐invasive device is efficient in wide‐angle thermal camouflage by rendering the same emissivity to the background medium and can self‐adjust to various even unknown background thermal fields, which is demonstrated in numerical simulations and experiments. This work opens a door to the 3D transformation‐thermotics‐based devices for versatile practical applications in thermal infrared stealth of macro‐sized objects and others.

AbstractMetal halide perovskite quantum dots (Pe‐QDs) are of great interest in new‐generation photovoltaics (PVs). However, it remains challenging in the construction of conductive and intact Pe‐QD films to maximize their functionality. Herein, a ligand‐assisted surface matrix strategy to engineer the surface and packing states of Pe‐QD solids is demonstrated by a mild thermal annealing treatment after ligand exchange processing (referred to as “LE‐TA”) triggered by guanidinium thiocyanate. The “LE‐TA” method induces the formation of surface matrix on CsPbI3 QDs, which is dominated by the cationic guanidinium (GA+) rather than the SCN−, maintaining the intact cubic structure and facilitating interparticle electrical interaction of QD solids. Consequently, the GA‐matrix‐confined CsPbI3 QDs exhibit remarkably enhanced charge mobility and carrier diffusion length compared to control ones, leading to a champion power conversion efficiency of 15.21% when assembled in PVs, which is one of the highest among all Pe‐QD solar cells. Additionally, the “LE‐TA” method shows similar effects when applied to other Pe‐QD PV systems like CsPbBr3 and FAPbI3 (FA = formamidinium), indicating its versatility in regulating the surfaces of various Pe‐QDs. This work may afford new guidelines to construct electrically conductive and structurally intact Pe‐QD solids for efficient optoelectronic devices.

Published: May 2020

AbstractLocalized surface plasmon resonance (LSPR) is shown to be effective in trapping light for enhanced light absorption and hence performance in photonic and optoelectronic devices. Implementation of LSPR in all‐inorganic perovskite nanocrystals (PNCs) is particularly important considering their unique advantages in optoelectronics. Motivated by this, the first success in colloidal synthesis of AuCu/CsPbCl3 core/shell PNCs and observation of enhanced light absorption by the perovskite CsPbCl3 shell of thickness in the range of 2–4 nm, enabled by the LSPR AuCu core of an average diameter of 7.1 nm, is reported. This enhanced light absorption leads to a remarkably enhanced photoresponse in PNCs/graphene nanohybrid photodetectors using the AuCu/CsPbCl3 core/shell PNCs, by more than 30 times as compared to the counterparts with CsPbCl3 PNCs only (8–12 nm in dimension). This result illustrates the feasibility in implementation of LSPR light trapping directly in core/shell PNCs for high‐performance optoelectronics.

AbstractA facile pathway of the electrocatalytic nitrogen oxidation reaction (NOR) to nitrate is proposed, and Ru‐doped TiO2/RuO2 (abbreviated as Ru/TiO2) as a proof‐of‐concept catalyst is employed accordingly. Density functional theory (DFT) calculations suggest that Ruδ+ can function as the main active center for the NOR process. Remarkably doping Ru into the TiO2 lattice can induce an upshift of the d‐band center of the Ru site, resulting in enhanced activity for accelerating electrochemical conversion of inert N2 to active NO*. Overdoping of Ru ions will lead to the formation of additional RuO2 on the TiO2 surface, which provides oxygen evolution reaction (OER) active sites for promoting the redox transformation of the NO* intermediate to nitrate. However, too much RuO2 in the catalyst is detrimental to both the selectivity of the NOR and the Faradaic efficiency due to the dominant OER process. Experimentally, a considerable nitrate yield rate of 161.9 µmol h−1 gcat−1 (besides, a total nitrate yield of 47.9 µg during 50 h) and a highest nitrate Faradaic efficiency of 26.1% are achieved by the Ru/TiO2 catalyst (with the hybrid composition of RuxTiyO2 and extra RuO2 by 2.79 wt% Ru addition amount) in 0.1 m Na2SO4 electrolyte.

AbstractTin selenide (SnSe) nanosheets, as 2D materials, exhibit many excellent optical and electronic properties and can be widely utilized in various potential applications, such as photodetectors, photovoltaic cells, optical sensors, and nonlinear optical devices. Herein, the 2D SnSe nanosheets are synthesized by the method combining lithium ion intercalation and sonication‐assisted liquid phase exfoliation. The morphology, structures, and chemical composition of as‐prepared 2D SnSe sample are systemically analyzed. Interestingly, the 2D SnSe nanosheets are successfully fabricated as a saturable absorber (SA) by depositing on a microfiber, which shows excellent nonlinear absorption property in a wide band. By incorporating SnSe‐based SA into the fiber lasers, stable mode‐locked pulses can be realized at 1.5 and 2 µm with a pulse duration of 0.542 and 2.12 ps, respectively. Additionally, harmonic mode locking of bound solitons is generated in the 1.5 µm fiber laser. Furthermore, dual‐wavelength mode‐locked pulses at 1897.3 and 1910.5 nm are also obtained in the 2 µm fiber laser. These results validate that 2D SnSe materials show great potential in nonlinear photonic devices for broadband ultrafast photonics.

Published: May 2020

AbstractThe shift of Fano resonances has been widely exploited to realize biomedical sensing, optical filtering, and optical switching. Here, the formation of Fano resonances in the scattering spectra of silicon nanoparticles excited by surface plasmon polaritons is reported and the modification of Fano lineshapes is demonstrated. It is revealed that the subradiant and superradiant modes responsible for the formation of Fano resonance originate from the coherent interaction of the electric and magnetic dipoles excited in the silicon nanoparticle with their mirror images induced by a thin metal film. The modification of the asymmetry parameter q can be realized by simply adjusting the angle of the incident light or by slightly varying the environment refractive index. The tuning of the q value is accompanied by the variation of the field enhancement factors and manifested in the color change of the scattered light. The strongest enhancement of both electric and magnetic fields can be achieved at the point of contact between the silicon nanoparticle and the metal film for the symmetric Fano lineshape (q ≈ 0). These findings indicate the potential applications of such a hybrid metal–dielectric system in sensing, color display, and strong light–matter interaction.

AbstractEngineering dynamic systems or materials to respond to biological process is one of the major tasks in synthetic biology and will enable wide promising applications, such as robotics and smart medicine. Herein, a super‐soft and dynamic DNA/dopamine‐grafted‐dextran hydrogel, which shows super‐fast volume‐responsiveness with high sensitivity upon solvents with different polarities and enables creation of electric circuits in response to microbial metabolism is reported. Synergic permanent and dynamic double networks are integrated in this hydrogel. A serials of dynamic hydrogel‐based electric circuits are fabricated: 1) triggered by using water as switch, 2) triggered by using water and petroleum ether as switch pair, 3) a self‐healing electric circuit; 4) remarkably, a microbial metabolism process which produces ethanol triggering electric circuit is achieved successfully. It is envisioned that the work provides a new strategy for the construction of dynamic materials, particularly DNA‐based biomaterials; and the electric circuits will be highly promising in applications, such as soft robotics and intelligent systems.

AbstractSjögren's syndrome is an autoimmune disease that may cause inflammation of exocrine glands, including the salivary glands. Some patients with Sjögren's syndrome also have gastrointestinal disease, such as gastroesophageal reflux disease. A few studies have shown that an association might exist between Sjögren's syndrome and esophageal motility disorder, but the results have been inconsistent. This study aimed to investigate the relationships between clinical symptoms and esophageal motility function in patients with Sjögren's syndrome. Fifty‐six patients with suspected esophageal reflux or motility disease who had undergone esophagogastroduodenoscopy and esophageal manometry were retrospectively enrolled. Thirteen patients were diagnosed as having Sjögren's syndrome according to the American‐European Consensus Criteria. Forty‐three patients without any rheumatic disease or esophageal motor disorder were designated as the control group. We compared the clinical symptoms and endoscopic and esophageal manometric findings between the Sjögren's syndrome and the control groups. Acid regurgitation was more prevalent in the Sjögren's syndrome group (53.8%) than in the control group (11.6%) (P = .003), but the endoscopic findings of reflux esophagitis were similar in both groups (Sjögren's: 38.5%; control: 39.5%; P = .945). Barrett's esophagus was more prevalent in the Sjögren's syndrome group than in the control group (15.4% vs 0%, respectively; P = .051). The upper esophageal sphincter was shorter in the Sjögren's syndrome group than in the control group (2.38 ± 0.65 cm vs 3.07 ± 0.74 cm, respectively; P = .003). More reflux symptoms and distinct motility patterns were found in the Sjögren's syndrome group as compared with the control subjects.
