Published: November 2020

Background
Different closed kinematic tasks may present different magnitudes of knee abduction, foot pronation, and foot plantar pressure and area. Although there are plenty of studies comparing knee abduction between different tasks, the literature lacks information regarding differences in foot pronation and foot plantar pressure and area. We compared foot angular displacement in the frontal plane and foot plantar pressure and area among five closed kinematic tasks.

Methods
Forefoot and rearfoot angular displacement and foot plantar pressure and area were collected in 30 participants while they performed the following tasks: stair descent, single-leg step down, single-leg squat, single-leg landing, and drop vertical jump. Repeated-measures analyses of variance were used to investigate differences between tasks with α = 0.05.

Results
Single-leg squat and stair descent had increased foot total plantar area compared with single-leg landing (P = .005 versus .027; effect size [ES] = 0.66), drop vertical jump (P = .001 versus P = .001; ES = 0.38), and single-leg step down (P = .01 versus P = .007; ES = 0.43). Single-leg landing and single-leg step down had greater foot total plantar area compared with drop vertical jump (P = .026 versus P = .014; ES = 0.54). There were differences also in rearfoot and midfoot plantar area and pressure and forefoot plantar pressure.

Conclusions
Differences in foot-striking pattern, magnitude of ground reaction force, and task speed might explain these findings. Clinicians should consider these findings to improve decisions about tasks used during rehabilitation of patients with foot conditions.
The uneasy coexistence between Carpet Pythons and Cane Toads
Authors: Brown Gregory P. , Hemphill Jeremy , Shine Richard 
Published: November 2020

ABSTRACT
We describe a case of a free-ranging Carpet Python Morelia spilota consuming a toxic Cane Toad Rhinella marina, and dying as a result. Such an encounter would not be surprising at the toad invasion front, where predators first confront this novel prey type. However, the encounter we describe occurred at a site near Darwin where toads have been present for fifteen years. Other reports suggest that the behaviour we observed occurs across the snake’s range. Lethal ingestion of toads has been suggested to threaten the viability of populations of Carpet Pythons, but paradoxically, our surveys at this site reveal a twofold increase in abundance of Carpet Pythons since the arrival of toads. Toad invasion likely has favoured pythons by reducing the abundance of large monitor lizards, that are both predators and competitors of Carpet Pythons. That advantage has outweighed occasional cases where a snake is fatally poisoned by consuming a toad. Thus, the overall impact of Cane Toads on Carpet Pythons (and likely, other predator species) is a balance between direct costs and indirect benefits. Negative impacts on individuals may not necessarily translate to a negative impact on the species.

Published: November 2020

Objective: The objective of this study was to carry out a comparative proximate and dietary fibre analysis of some leafy vegetables commonly consumed in the Niger Delta region, Nigeria.
Methodology: The selected vegetables were Ugu leaf (Telfairia occidentalis), Water leaf (Talinum triangulare), Bitter leaf (Vernonia amygdalina), Scent leaf (Ocimum gratissimum) and Green leaf (Spinacia oleracea). These leaves were harvested from the University school farms of University of Uyo, Akwa Ibom, Rivers State University and Delta State University to represent the Niger Delta region of Nigeria. The samples were analyzed for proximate composition and dietary fibres using standard methods.
Results: Moisture, ash, fat, crude protein, crude fibre and carbohydrate contents of the leafy vegetables ranged from 70.95-92.11%, 1.90-5.18%, 0.07-1.47%, 1.54-8.78%, 1.90-7.89% and 1.42-10.54%, respectively. Total dietary and insoluble fibres of the vegetables grown in Niger Delta regions of Nigeria ranged from 4.10-23.12%. Dietary fibre of pumpkin leaves grown in Rivers and Akwa Ibom states as well as scent leaf from Rivers state were significantly (p<0.05) higher than vegetables from other states.
Conclusion: The result of this study therefore reveals that the proximate composition and dietary fibre content of the vegetables were significantly (p<0.05) affected by the locations in which they were harvested.

Cytochromes P450 (CYPs or P450s) comprise a superfamily of heme‐containing monooxygenases that are involved in a variety of biological processes. CYPs have broad utilities in industry, but most exhibit low thermostability, limiting their use on an industrial scale. Highly thermostable enzymes can be obtained from thermophiles in geothermal areas, including hot springs, offshore oil‐producing wells and volcanoes. Here, we report the identification of a gene encoding for a thermophilic CYP from the Binh Chau hot spring metagenomic database, which was designated as P450‐T2. The deduced amino acid sequence showed the highest identity of 73.15% with CYP203A1 of Rhodopseudomonas palustris, supporting that P450‐T2 is a member of the CYP203A subfamily. Recombinant protein expression yielded 541 nm. The optimal temperature and pH of P450‐T2 were 50 °C and 8.0, respectively. The half‐life of P450‐T2 was 50.2 min at 50 °C, and its melting temperature was 56.80 ± 0.08 °C. It was found to accept electrons from all tested redox partners systems, with BmCPR‐Fdx2 being the most effective partner. Screening for putative substrates revealed binding of phenolic compounds, such as l‐mimosine and emodin, suggesting a potential application of this new thermophilic P450 in the production of the corresponding hydroxylated products.

AbstractGiven that it is a potential medium for 3D manipulation of photons in the forward‐looking technology of quantum optics, nonlinear optics, electronics, nanomaterials, and bionics, 3D photonic crystal (PhC) is a promising material of strategic significance and has great impact on scientific development. Blue phase (BP), a liquid crystalline mesophase with unique nanoscaled 3D PhC features, has been shown to contain significant potential values in fundamental studies and technological applications. However, thus far, the environmental stability of BP devices remains a puzzling issue of material exploitation. Therefore, in this study, stretching‐tunable BP elastomer (BPE) photonic bandgap (PBG) free‐standing films are fabricated via full photopolymerization. The BPE films exhibit benefit‐specific features, including sharp PBG with high reflectivity and flexible tunability in the visible region, high thermal stability, and good mechanical ductility and resistance in chemicals. These properties are attributed to the pre‐developed, fully‐reactive mesogenic materials employed, which show BP states in a wide temperature range, including room temperature. Additionally, mirrorless laser applications with flexible tunability are also realized in this study. The freestanding BPE film can be used as a prototype instrumentality to promote the future development of multifunctional intelligent applications in lasers, sensors, displays, intelligent lightings, lidars, micro‐robots and antennas.
Halide Perovskites: A Progress Report on Photon Interconversion
Authors: Wieghold Sarah , VanOrman Zachary A. , Nienhaus Lea 
Published: November 2020

AbstractPhoton interconversion generally describes processes which change the wavelength of the emitted light upon irradiation, with a gain in photon energy (upconversion), or a splitting of the incident photon energy to create multiple photons (downconversion). The focus of this progress report is placed on halide perovskite materials and their role in upconversion by triplet–triplet annihilation and downconversion via singlet fission in organic semiconductors, and a short perspective is given into quantum cutting and lanthanide‐based upconversion applications. The current advances are highlighted regarding halide perovskites and perovskite‐inspired materials with varying framework and material dimensionalities, as relating to photon interconversion processes. The majority of the literature is based on 3D perovskites, which leaves room for growth for perovskite materials with varying dimensionalities. Gaps in the current field are emphasized, leading to a bright outlook on future possibilities of coupling perovskites to photon interconversion mechanisms, which can open the door for future breakthroughs in this field.
Ruthenium Catalyzed C−H Amidation and Carbocyclization using Isocyanates: An Access to Amidated 2‐phenylphthalazine‐1,4‐diones and Indazolo[1,2‐b]phthalazine‐triones

Published: November 2020

AbstractA direct carbocyclization of 2‐aryl‐2,3‐dihydrophthalazine‐1,4‐diones is achieved using isocyanates as carbonyl source via Ru(II)‐catalyzed sequential ortho‐amidation followed by intramolecular nucleophilic substitution, delivering substituted indazolo[1,2‐b]phthalazine‐triones in good‐to‐excellent yields. For ortho‐substituted 2‐aryl‐2,3‐dihydrophthalazine‐1,4‐diones, the corresponding amidated products were also isolated in excellent yields by modifying the reaction parameters. Application of isocyanates as carbonyl source, high functional group tolerance on the two coupling partners and diverse chemical transformation of the synthesized fused and functionalized phthalazinones are the key highlights of the work.magnified image
Biological traits of six sterile oat biotypes in response to planting time
Authors: Mahajan Gulshan , Chauhan Bhagirath S. 
Published: November 2020

AbstractSterile oat (Avena ludoviciana Durieu) is a problematic weed in winter crops of Australia. Biotypes of sterile oat adapted to the local environment may vary in environmental plasticity, which could increase their invasiveness. A 2‐yr (winter growing seasons of 2018 and 2019) study in Australia investigated the influence of planting date (early, mid‐, and late season) on the growth and reproduction potential of six biotypes (AL2/17, AL3/17, AL4/17, AL5/17, AL6/17, and AL9/17) of sterile oat. Averaged across biotypes, the seed production of sterile oat was reduced by 21 and 84% for mid‐ and late planting, respectively, compared with early planting (2,660 seeds plant−1). Seed production was highly correlated with the first panicle emergence for early planting. However, for mid‐ and late‐season planting, seed production was correlated with panicle number and plant biomass. For mid‐season planting, taller plants had more seed number plant−1 than shorter plants. The results of this study imply that biotypes of sterile oat differ in environmental plasticity and that they can complete their life cycle under a wide range of temperatures in the winter season and contribute to its reinfestation. Results also suggest that early and mid‐season cohorts are prolific in seed production; however, late cohorts can also produce sufficient seeds for reinfestation. Therefore, integrated weed management strategies must be focussed on those tactics (manipulation of sowing time and row spacing) that could create a competitive crop environment and to suppress the growth of early cohorts of sterile oat to reduce their seed production.

Published: November 2020

AbstractThe effective non‐precious metal catalysts toward the oxygen evolution reaction (OER) are highly desirable for electrochemical water splitting. Herein, we prepare a novel glass‐ceramic (Ni1.5Sn@triMPO4) by embedding crystalline Ni1.5Sn nanoparticles into amorphous trimetallic phosphate (triMPO4) matrix. This unique crystalline‐amorphous nanostructure synergistically accelerates the surface reconstruction to active Ni(Fe)OOH, due to the low vacancy formation energy of Sn in glass‐ceramic and high adsorption energy of PO43− at the VO sites. Compared to the control samples, this dual‐phase glass‐ceramic exhibits a remarkably lowered overpotential and boosted OER kinetics after surface reconstruction, rivaling most of state‐of‐the‐art electrocatalysts. The residual PO43− and intrinsic VO sites induce redistribution of electron states, thus optimizing the adsorption of OH* and OOH* intermediates on metal oxyhydroxides and promoting the OER activity.

Published: November 2020

AbstractFacilitating the dissociation of water and desorption of hydrogen are both crucial challenges for improving the hydrogen evolution reaction (HER) in alkaline media. Herein, we report the synthesis of heterostructure of Ru2P/WO3@NPC (N, P co‐doped carbon) by a simple hydrothermal reaction using ruthenium and tungsten salts as precursors, followed by pyrolyzing under an Ar atmosphere. The Ru2P/WO3@NPC electrocatalyst exhibits an outstanding HER activity with an overpotential of 15 mV at a current density of 10 mA cm−2 and excellent durability in a 1.0 M KOH solution, outperforming state‐of‐the‐art Pt/C and most reported electrocatalysts. Experimental results combined with density functional calculations reveal that the electron density redistribution in Ru2P/WO3@NPC is achieved by electron transfer from NPC to Ru2P/WO3 and from Ru2P to WO3, which directly promotes the dissociation of water on W sites in WO3 and desorption of hydrogen on Ru sites in Ru2P.
Codoping of Lead‐Free Double Perovskites Promotes Near‐Infrared Photoluminescence
Authors: Wang Chao , Zhao Guangjiu 
Published: November 2020

AbstractIn the rapidly developing smart era, near‐infrared luminescent materials have important applications in various fields that are closely related to people. Nag and co‐workers provided a first codoping strategy to achieve efficient near‐infrared photoluminescence in lead‐free double perovskite materials. Through the introduction of Bi3+ ions, a new energy state is formed that leads to the absorption of lower‐energy light. The excited state formed by this light absorption subsequently excites f‐electrons of Er3+ or Yb3+ ions, and the relaxation of these f‐electrons results in near‐infrared photoluminescence. This may open a new chapter in the application of perovskites for infrared detection and human sensing.
Zinc Metal Energy Storage Devices under Extreme Conditions of Low Temperatures
Authors: Li Fuyun , Hu Xianluo 
Published: November 2020

AbstractZinc‐based energy storage devices have received extensive attention because of their low‐cost and high‐safety characteristics. Numerous breakthroughs have been made in this field in recent years. Some special applications, such as polar inspections, oil exploration, high‐altitude drones, aerospace, and cold regions, place higher requirements on the performance of zinc‐based energy storage devices under extreme conditions of low temperatures. However, aqueous electrolytes will freeze at sub‐zero temperatures, resulting in device failure. Besides, the sluggish kinetics of the electrodes at low temperatures limits their capacity retention and rate performance. During the past several years, considerable efforts have been devoted to circumventing these problems. In this review, we summarize the recent progress on zinc metal energy storage devices under extreme conditions of low temperatures. Three aspects including the design of anti‐freezing electrolytes, low‐temperature‐resistant cathode materials, and zinc anodes are discussed. Finally, a perspective on this field is summarized to guide future researches.

Published: November 2020

AbstractCongenital heart diseases are one of the most common multi‐factorial fetal abnormalities caused by a complex of endo‐ and exogenous factors. It is known that mutations in xenobiotic biotransformation genes can be associated with the pathogenesis of congenital heart diseases. In the presented research, 131 children with congenital heart diseases and 101 women having children with this pathology were included in the study group. In control group, 103 healthy children and their mothers were included. Single‐nucleotide polymorphisms in the xenobiotic biotransformation genes CYP1A1 (rs1048943), CYP1A2 (rs762551), GSTP1 (rs6591256, rs1871042 and rs17593068) were detected by the real‐time polymerase chain reaction. Gene–gene interactions were determined using the Multifactor Dimensionality Reduction method. We obtained no difference in the frequency of CYP1A1, CYP1A2 and GSTP1 between the study and control groups. At the same time, the genetic combinations GSTP1 (rs6591256)—GSTP1 (rs1871042) and GSTP1 (rs6591256)—GSTP1 (rs1871042)—CYP1A1 (rs1048943) in women; and GSTP1 (rs1793068)—GSTP1 (rs6591256)—GSTP1 (rs1871042)—CYP1A1 (rs1048943)—CYP1A2 (rs762551) in children contribute to the pathogenesis of congenital heart diseases.
