Inhibition of lithium dendrites and dead lithium by an ionic liquid additive toward safe and stable lithium metal anodes

The uncontrolled growth of lithium dendrites and accumulation of "dead lithium" upon cycling are among the main obstacles that hinder the widespread application of lithium metal anodes. Herein, an ionic liquid(IL)consisting of 1-methyl-1-propylpiperidinium cation(Pp_(13)~+)and bis(fluorosulfonyl)imide anion(FSI~-), was chosen as the additive in propylene carbonate(PC)-based liquid electrolytes to circumvent the shortcoming of lithium metal anodes. The optimal 1% Pp_(13)FSI acts as the role of electrostatic shielding, lithiophobic effect and participating in the formation of solid electrolyte interface(SEI)layer with enhanced properties. The in-situ optical microscopy records that the addition of IL can effectively inhibit the growth of lithium dendrites and the corrosion of lithium anode. This study delivers an effective modification to optimize electrolytes for stable lithium metal batteries.
A bi-component polyoxometalate-derivative cathode material showed impressive electrochemical performance for the aqueous zinc-ion batteries

Rechargeable aqueous zinc-ion batteries are recently gaining incremental attention because of low cost and material abundance, but their development is plagued by limited choices of cathode materials with satisfactory cycling performance. The polyoxometalates perform formidable redox stability and able to participate in multi-electron transfer, which was well-suited for energy storage. Herein, a bicomponent polyoxometalate-derivative KNiVO(K_2[Ni(H_2O)_6]_2[V_(10)O_(28)]·4H_2O polyoxometalates after annealing)is firstly demonstrated as a cathode material for aqueous ZIBs. The layered KV_3O_8(KVO)In the bi-component material constitutes Zn~(2+) migration and storage channels(K~+ were substantially replaced by Zn~(2+) in the activation phase), and the three-dimensional NiV_3O_8(NiVO)part acts as skeleton to stabilize the ion channels, which assist the cell to demonstrate a high-rate capacity and specific energy of 229.4 mAh/g and satisfactory cyclability(capacity retention of 99.1% after 4500 cycles at a current density of 4 A/g). These results prove the feasibility of POM as cathode materials precursor and put forward a novel pattern of the Zn~(2+) storage mechanism in the activated-KNiVO clusters, which also provide a new route for selecting or designing high-performance cathode for aqueous ZIBs and other advanced battery systems.
Sandwich-like QDs/MOFs films for selective sensing and multicolor emitting

A novel type sandwich-like composite films composed of ZIF-8 and CdTe QDs were successfully constructed through facile layer-by-layer assembly strategy and their potential applications were also explored. Based on the limitation effects of the aperture of ZIF-8, CdTe QDs/ZIF-8 fluorescent composite films exhibit obvious selective optical response toward hydrogen peroxide and folic acid. Furthermore, tunable colorful light emission composite films in the red-green region are obtained through incorporating two different sized QDs and ZIF-8 films into one composite films.
N, O co-doped porous carbon with rich pseudocapacitive groups exhibiting superior energy density in an acidic 2.4 V Li_2SO_4 electrolyte

Designing a carbon material with a unique composition and surface functional groups for offering high specific capacity in a wide voltage window is of great significance to improve the energy density for the supercapacitor in a cheap and eco-friendly aqueous electrolyte. Herein, we develop an efficient strategy to synthesize a N, O co-doped hierarchically porous carbon(NODPC-1.0)with moderate specific surface area and pore volume as well as rich heteroatoms using a deep eutectic solvent(DES)as an activator. It is found that NODPC-1.0 with a large proportion of pseudocapacitive functional groups(pyrrole-N, pyridine- N and carbonyl-quinone)can work stable in an acidic 2 mol/L Li_2SO_4(pH 2.5)electrolyte, exhibiting specific capacities of 375 and 186 F/g at the current densities of 1.0 and 100 A/g, respectively. Also, the assembled symmetric capacitor using the NODPC-1.0 as the active material and 2 mol/L acidic Li_2SO_4(pH 2.5)as the electrolyte shows an outstanding energy density of 74.4 Wh/kg at a high power density of 1.44 kW/kg under a broad voltage window(2.4 V). Relevant comparative experiments indicate that H~+of the acidic aqueous electrolyte plays a crucial part in enhancement the specific capacity, and the abundant pseudocapacitive functional groups on the surface of the NODPC-1.0 sample play the key role in the improvement of electrochemical cycle stability under a broad voltage window.
Hierarchical metal-phenolic-polyplex assembly toward superwetting membrane for high-flux and antifouling oil-water separation

Superwetting membranes have emerged as promising materials for the efficient treatment of oily wastewater. Typically, superwetting membranes can be developed by ingeniously chemical modification and topographical structuration of microporous membranes. Herein, we report the hierarchical assembly of metal-phenolic-polyplex coating to manipulate membrane surface superwettability by integrating metal-phenolic(Fe~(III)-tannic acid(TA))assembly with polyplex(tannic acid-polyethylenimine(PEI))assembly. The proposed Fe-TA-PEI coating can be deposited on microporous membrane via simply dipping into Fe~(III)-TA-PEI co-assembly solution. Based on the catechol chemistry, the coordination complexation of Fe~(III)and TA develops metal-phenolic networks to provide hydrophilic chemistries, and the electrostatic complexation of TA and PEI generates nanoconjugates to impart hierarchical architectures. Benefiting from the synergy of hydrophilic chemistries and hierarchical architectures, the resulting PVDF/Fe-TA-PEI membrane exhibits excellent superhydrophilicity(~0°), underwater superoleophobicity(~150°)and superior anti-oil-adhesion capability. The superhydrophilicity of PVDF/Fe-TA-PEI membrane greatly promotes membrane permeability, featuring water fluxes up to 5860 L m~(-2) h~(-1). The underwater superoleophobicity of PVDF/Fe-TA-PEI membrane promises potential flux(3393 L m~(-2) h~(-1)), high separation efficiency(99.3%)and desirable antifouling capability for oil-in-water emulsion separation. Thus, we highlight the reported hierarchical metal-phenolic-polyplex assembly as a straightforward and effective strategy that enables the synchronous modulation of surface chemistry and topography toward superwetting membranes for promising high-flux and antifouling oil-water separation.
New exact solutions to the Eddingtoninspired- Born-Infeld equations for a relativistic perfect fluid in a Bianchi type I spacetime

We consider a Bianchi type I physical metric g, an auxiliary metric q and a density matter ρ in Eddington-inspired-Born-Infeld theory. We first derive a system of second order nonlinear ordinary differential equations. Then, by a suitable change of variables, we arrive at a system of first order nonlinear ordinary differential equations. Using both the solution-tube concept for the first order nonlinear ordinary differential equations and the nonlinear analysis tools such as the Arzela-Ascoli theorem, we prove an existence result for the nonlinear system obtained. The resolution of this last system allows us to obtain new exact solutions for the model considered. Finally, by studying the asymptotic behaviour of the exact solutions obtained, we conclude that this solution is the counterpart of the Friedman-Lemaitre-Robertson-Walker spacetime in Eddington-inspired-Born-Infeld theory.
Four-family N = 1 supersymmetric Pati- Salam models from intersecting D6-branes

We investigate the construction of four-family N = 1 supersymmetric Pati-Salam models from Type IIA T~6/Z_2 × Z_2 orientifold with intersecting D6-branes. Utilizing the deterministic algorithm introduced in He W, Li T and Sun R(2021 arXiv: hep-th/2112.09632), we obtain 274 types of models with three rectangular tori and distinct gauge coupling relations at string scale, while 6 types of models with two rectangular tori and one tilted torus. In both cases, there exists a class of models with gauge coupling unification at string scale. In particular, for the models with two rectangular tori, one tilted torus and gauge coupling unification, the gaugino condensations are allowed, and thus supersymmetry breaking and moduli stabilization are possible for further phenomenological study.
Luminescence Dating and Bracketing Time of the Youngest Toba Tuff Deposits in the Quaternary Sediments of Purna Alluvial Basin, Central India

Light gray to yellowish brown youngest Toba tuff (YTT) ash, preserved in the Quaternary sediments of India, have been used as a tool to know depositional and bracketing time period of the same in the sediments through applications of luminescence dating to interpret age connotation of various geological events. Pre- and post-tephra sediments of YTT ash beds from Hudki and Sukali areas of Purna alluvial basin, Central India have been optically dated to interpret the depositional age and bracketing time of the tephra within sedimentary sequences. These sediments are yellowish brown, thinly bedded, laminated, silty clay and host laterally extend discontinued beds of 0.15–0.20 m thickness. The ash is light gray, fine grained and powdery in nature, massive to structureless and lacks any sign of retransportation and redeposition, hence, considered as primary in nature. Total four sediment samples, one each from pre- and post-tephra lithounits of both the localities have been dated through optically stimulated luminescence technique (OSL) equipped with single aliquot regenerative (SAR) procedure on the feldspar grains. It shows pre- and post-tephra ages of 57 ± 5 and 70 ± 4 ka respectively for Hudki and 66 ± 5 and 67 ± 4 ka for Sukali localities. These depositional ages suggest that the ash was bracketed within sediments thousands years after YTT eruption. It is correlatable with the previously reported depositional and absolute ages for the YTT ash from the localities of Ghoghara and Khuntheli, Son Valley; Tejpur, Madhumati River Basin and Jwalapuram, Jurreru Valley. These ages also provide an idea about the period of existence of biological communities represented by the remains of faunal and vegetational activities before and during settlement of the YTT ash in the basin area.
An elliptical blade is not a true ellipse, but a superellipse–Evidence from two Michelia species

The shape of leaf laminae exhibits considerable diversity and complexity that reflects adaptations to environmental factors such as ambient light and precipitation as well as phyletic legacy. Many leaves appear to be elliptical which may represent a ‘default' developmental condition. However, whether their geometry truly conforms to the ellipse equation (EE), i.e., (x/a)~2 + (y/b)~2 = 1, remains conjectural. One alternative is described by the superellipse equation (SE), a generalized version of EE, i.e., | x/a |~n +| y/b |~n = 1. To test the efficacy of EE versus SE to describe leaf geometry, the leaf shapes of two Michelia species (i.e., M. cavaleriei var. platypetala, and M. maudiae), were investigated using 60 leaves from each species. Analysis shows that the majority of leaves (118 out of 120) had adjusted root-mean-square errors of < 0.05 for the nonlinear fitting of SE to leaf geometry, i.e., the mean absolute deviation from the polar point to leaf marginal points was smaller than 5% of the radius of a hypothesized circle with its area equaling leaf area. The estimates of n for the two species were < 2, indicating that all sampled leaves conformed to SE and not to EE. This study confirms the existence of SE in leaves, linking this to its potential functional advantages, particularly the possible influence of leaf shape on hydraulic conductance.
Dimensional Reduction of Eu-Based Metal-Organic Framework as Catalysts for Oxidation Catalysis of C(sp~3)-H Bond

Developing new catalysts for highly selectivity and conversion of saturated C(sp~3)-H bonds is of great significance. In order to obtain catalysts with high catalytic performance, six Eu-based MOFs with different structural characteristics were obtained by using europium ions and different organic acid ligands, namely Eu-1~Eu-6. Eu-1, Eu-2 and Eu-3 featured three-dimensional structures, while Eu-4 and Eu-5 featured two-dimensional structures. Differently, a one-dimensional chain structure of Eu-6 was obtained by changing the ligand. All the six MOFs were applied to the catalytic reaction of C(sp~3)-H bond, and it was found that the catalytic effect was gradually enhanced with the decrease of dimension and the increase of the size of channels. As expected, Eu-6 showed the highest selectivity(~99%) and conversion(~99%). Moreover, catalytic cycling and stability tests showed Eu-6 can be a reliable catalyst.
Dynamics of COVID-19 pandemic in India and Pakistan: A metapopulation modelling approach

India has been the latest global epicenter for COVID-19, a novel coronavirus disease that emerged in China in late 2019.We present a base mathematical model for the transmission dynamics of COVID-19 in India and its neighbor, Pakistan. The base model was rigorously analyzed and parameterized using cumulative COVID-19 mortality data from each of the two countries. The model was used to assess the population-level impact of the control and mitigation strategies implemented in the two countries (notably non-pharmaceutical interventions). Numerical simulations of the basic model indicate that, based on the current baseline levels of the control and mitigation strategies implemented, the pandemic trajectory in India is on a downward trend. This downward trend will be reversed, and India will be recording mild outbreaks, if the control and mitigation strategies are relaxed from their current levels. By early September 2021, our simulations suggest that India could record up to 460,000 cumulative deaths under baseline levels of the implemented control strategies, while Pakistan (where the pandemic is comparatively milder) could see over 24,000 cumulative deaths at current mitigation levels. The basic model was extended to assess the impact of back-and-forth mobility between the two countries. Simulations of the resulting metapopulation model show that the burden of the COVID-19 pandemic in Pakistan increases with increasing values of the average time residents of India spend in Pakistan, with daily mortality in Pakistan peaking in mid-August to mid-September of 2021. Under the respective baseline control scenarios, our simulations show that the backand-forth mobility between India and Pakistan could delay the time-to-elimination of the COVID-19 pandemic in India and Pakistan to November 2022 and July 2022, respectively.
Synthesis of Axially Chiral Anilides Enabled by a Palladium/Ming-Phos-Catalyzed Desymmetric Sonogashira Reaction

Atropisomeric anilides are one of important C-N axially chiral compounds. Compared with the N-terminal functionalization to prepare such compounds, C-terminal functionalization strategies have been rarely reported. We describe herein an efficient synthesis of axially chiral anilides enabled by Pd-catalyzed desymmetric Sonogashira cross-coupling reactions with the use of a newly identified Ming-Phos. Moderate to high yields with high enantioselectivities (up to 98% ee) were obtained.
SCHISTOX: An individual based model for the epidemiology and control of schistosomiasis

A stochastic individual based model, SCHISTOX, has been developed for the study of schistosome transmission dynamics and the impact of control by mass drug administration. More novel aspects that can be investigated include individual level adherence and access to treatment, multiple communities, human sex population dynamics, and implementation of a potential vaccine. Many of the model parameters have been estimated within previous studies and have been shown to vary between communities, such as the age-specific contact rates governing the age profiles of infection. However, uncertainty remains as there are wide ranges for certain parameter values and a few remain relatively unknown.We analyse the model dynamics by parameterizing it with published parameter values. We also discuss the development of SCHISTOX in the form of a publicly available open-source GitHub repository. The next key development stage involves validating the model by calibrating to epidemiological data.
Strategic options for syphilis control in Papua New Guineae impact and cost-effectiveness projections using the syphilis interventions towards elimination (SITE) model

Objectives: Papua New Guinea (PNG) has among the highest rates of sexually transmitted infections (STIs) globally and is committed to reducing their incidence. The Syphilis Interventions Towards Elimination (SITE) model was used to explore the expected impact and cost of alternative syphilis intervention scale-up scenarios. Methods: SITE is a dynamical model of syphilis transmission among adults 15-49 years. Individuals are divided into nine groups based on sexual behaviour and into six stages of infection. The model was calibrated to PNG using data from routine surveillance, biobehavioural surveys, research studies and program records. Inputs included syphilis prevalence, risk behaviours, intervention coverage and service delivery unit costs. Scenarios compared different interventions (clinical treatment, contact tracing, syphilis screening, and condom promotion) for incidence and cost per infection averted over 2021-2030.
Graph modelling for tracking the COVID-19 pandemic spread

The modelling is widely used in determining the best strategies for the mitigation of the impact of infectious diseases. Currently, the modelling of a complex system such as the spread of COVID-19 infection is among the topical issues. The aim of this article is graphbased modelling of the COVID-19 infection spread. The article investigates the studies related to the modelling of COVID-19 pandemic and analyses the factors affecting the spread of the disease and its main characteristics. We propose a conceptual model of COVID-19 epidemic by considering the social distance, the duration of contact with an infected person and their location-based demographic characteristics. Based on the hypothetical scenario of the spread of the virus, a graph model of the process are developed starting from the first confirmed infection case to human-to-human transmission of the virus and visualized by considering the epidemiological characteristics of COVID-19. The application of graph for the pandemic modelling allows for considering multiple factors affecting the epidemiological process and conducting numerical experiments. The advantage of this approach is justified with the fact that it enables the reverse analysis the spread as a result of the dynamic record of detected cases of the infection in the model. This approach allows for to determining undetected cases of infection based on the social distance and duration of contact and eliminating the uncertainty significantly. Note that social, economic, demographic factors, the population density, mental values and etc. affect the increase in number of cases of infection and hence, the research was not able to consider all factors. In future research will analyze multiple factors impacting the number of infections and their use in the models will be considered.
The Fold-Illuminator: A low-cost, portable, and disposable incubator-illuminator device

Fluorescent reporters have revolutionized modern applications in the fields of molecular and synthetic biology, enabling applications ranging from education to point-of-care diagnostics. Past advancements in these fields have primarily focused on improving reaction conditions, the development of new applications, and the broad dissemination of these technologies. However, field and classroom-based applications have remained limited in part due to the nature of fluorescent signal detection, which often requires the use of costly lab equipment to observe and quantify fluorescence readouts. Users without access to laboratory equipment rely on qualitative assessments of fluorescence, a process that remains highly variable from user-to-user even within the same classroom. To overcome this challenge, we have developed a foldable illuminator and incubator device to support field-applications of synthetic biology-based biosensors for education and diagnostics. The Fold-Illuminator is an affordable, portable, and recyclable device that allows for the visible detection of fluorescent biomolecules. The Fold-Illuminator’s design allows for assembly in under 10 min, a user can then utilize the optional heating element to incubate biochemical reactions and visualize fluorescence outputs in a defined and light-controlled environment. Interchangeable LED strips and light-filtering screens provide modularity to pair with the fluorescence wavelengths of interest. The user can then unfold the device for convenient storage, transport, or even recycling. The cost for the Fold-Illuminator is $5.58 USD and is compatible with an optional heating element for an additional $3.98 cost, with potential for further reductions in cost for larger quantities. Open-source templates for cutting device parts from paper stock are provided for both printing and cutting by hand; cutting can also be achieved with consumer-grade smart cutting machines such as the Cricut®. Combined with the broad applications of fluorescent reporters, the Fold-Illuminator has the potential to improve access to fluorescence visualization and quantification for new users as well as emerging field applications.

腹腔镜手术老年患者术前痛阈与术后谵妄的相关性

术后谵妄(postoperative delirium,POD)是一种短暂性非特定的实质器官脑部综合征,常见于老年患者。POD会增加坠床、呼吸困难、心肌梗死等其他并发症的发生,从而明显延长住院时间、增加医疗费用、升高死亡率[1]。研究[2-3]表明,发生POD的老年患者6个月内的死亡率高达25%。优化术后疼痛管理可降低POD风险[4]。目前,关于POD和术后疼痛的研究取得一定的进展,但由于二者均受多因素共同影响,其发生机制及病理生理未完全明确,关于术前痛阈和POD的关系亦不清楚。知觉痛觉定量分析仪是目前广泛应用的测量疼痛指标的仪器,它利用电刺激,测定患者对不同强度电流的感知程度,进一步定量测得疼痛敏感度指标数值,简单客观,可重复操作,对组织损伤较少[5]。因此,本研究拟对行腹腔镜手术的老年患者术前测定痛阈,分析术前痛阈与POD的相关性。
甲基苯丙胺与乙醇联合作用中毒致死1例

甲基苯丙胺类药物致死案需结合案情、法医学检查,特别是毒物检验,判断毒药物之间是否有协同作用,排除其他可能致死的因素,全面分析并最终得出正确结论。此外,死后再分布的影响,心血中毒物浓度在死后短时间内会出现上升,因此怀疑中毒死亡的案例,应尽早进行尸体解剖并提取外周血进行毒物检验。
