Published: March 2024

AbstractLithium metal battery has been regarded as promising next‐generation battery system aiming for higher energy density. However, the lithium metal anode suffers severe side‐reaction and dendrite issues. Its electrochemical performance is significantly dependant on the electrolyte components and solvation structure. Herein, a series of fluorinated ethers are synthesized with weak‐solvation ability owing to the duple steric effect derived from the designed longer carbon chain and methine group. The electrolyte solvation structure rich in AGGs (97.96 %) enables remarkable CE of 99.71 % (25 °C) as well as high CE of 98.56 % even at −20 °C. Moreover, the lithium‐sulfur battery exhibits excellent performance in a wide temperature range (−20 to 50 °C) ascribed to the modified interphase rich in LiF/LiO2. Furthermore, the pouch cell delivers superior energy density of 344.4 Wh kg−1 and maintains 80 % capacity retention after 50 cycles. The novel solvent design via molecule chemistry provides alternative strategy to adjust solvation structure and thus favors high‐energy density lithium metal batteries.

AbstractThe homoleptic magnesium bis(aluminyl) compound Mg[Al(NON)]2 (NON=4,5‐bis(2,6‐diisopropylanilido)‐2,7‐di‐tert‐butyl‐9,9‐dimethylxanthene) can be accessed from K2[Al(NON)]2 and MgI2 and shown to possess a non‐linear geometry (∠Al−Mg−Al=164.8(1)°) primarily due to the influence of dispersion interactions. This compound acts a four‐electron reservoir in the reductive de‐fluorination of SF6, and reacts thermally with polar substrates such as MeI via nucleophilic attack through aluminium, consistent with the QT‐AIM charges calculated for the metal centres, and a formal description as a Al(I)−Mg(II)−Al(I) trimetallic. On the other hand, under photolytic activation, the reaction with 1,5‐cyclooctadiene leads to the stereo‐selective generation of transannular cycloaddition products consistent with radical based chemistry, emphasizing the covalent nature of the Mg−Al bonds and a description as a Al(II)−Mg(0)−Al(II) synthon. Consistently, photolysis of Mg[Al(NON)]2 in hexane in the absence of COD generates [Al(NON)]2 together with magnesium metal.

Published: March 2024

AbstractSelf‐repairing materials aim to replicate nature's repair mechanisms, but their current properties are inadequate for commercialization due to the trade‐off between repair and mechanical properties. An environmentally responsive low‐temperature self‐healing aqueous polyurethane with different sequence structures was developed in which the WPU‐MD/APDS system exhibited excellent performance. Statically, the incorporation of MD (1,8‐diamino‐P‐menthane) enhances hydrogen bonding within the system and facilitates reversible weak dynamic bonding; microphase separation enables aggregation of disulfide bonds in the hard‐phase domain, thereby improving disulfide bond exchange rates. Dynamically, the inclusion of MD introduces a rigid ring structure and promotes microphase separation with increased hydrogen bonding, leading to enhanced mechanical properties of the materials. The material exhibited tensile strength of 27.37 MPa, elongation at break of 1353%, excellent elastic recovery ability, and high tensile toughness of 136 MJ m−3; a sample with thickness of 0.2 mm lifted weight greater than its own weight into 40,000 times without damage recovery at 40°C. Rheological analysis confirmed its self‐healing property at room temperature.
Unsupervised tail modeling via noisy cross‐entropy minimization
Authors: Bee Marco 
Published: March 2024

AbstractEstimation of dynamic mixture distributions is a difficult task, because the density contains an intractable normalizing constant. To overcome this difficulty, we develop an approach that maximizes, by means of the cross‐entropy method, a Monte Carlo approximation of the log‐likelihood function. The proposed noisy cross‐entropy approach is unsupervised, since it does not require the specification of a threshold between the distributions. Moreover, it bypasses the evaluation of the normalizing constant, combining good statistical properties with a modest computational burden. Both simulation‐based evidence and empirical applications suggest that noisy cross‐entropy estimation is comparable or preferable to existing methods in terms of statistical efficiency, but is less demanding from the computational point of view.
New developments in cosmetic applications of electromagnetic fields: Client and occupational hazard assessment
Authors: Stam Rianne 
Published: March 2024

AbstractEnergy‐based devices are used to improve features of appearance for aesthetic reasons while avoiding more invasive methods. Examples of treatment targets are the reduction of wrinkles, sagging, unwanted skin lesions, body hair and excess fatty tissue, and the enhancement of muscle tissue. One treatment modality is the use of electromagnetic fields (EMF, 0‒300 GHz). The present work aims to give an up‐to‐date survey of cosmetic applications of EMF for professional use with an assessment of client and worker exposure and possible adverse effects. A systematic search was conducted for peer‐reviewed articles (2007–2022), patents, premarket notifications, manufacturer data, and adverse effects reports. Five categories of cosmetic EMF device with increasing frequency were identified: sinusoid low frequency magnetic fields for lipolysis; pulsed low frequency magnetic fields for skin rejuvenation; pulsed low frequency magnetic fields for muscle building; radiofrequency EMF for lipolysis or skin rejuvenation; microwaves for hair removal or hyperhidrosis. In the vicinity of the last four device categories, there is a potential for exceeding the occupational exposure limits in the European Union EMF Directive, which could lead to nerve or muscle stimulation, burns or overheating. There are also potential hazards for clients or workers wearing active or passive medical devices. The severity of reported adverse effects increases with EMF frequency.
Investigating the effect of Zn doping and temperature on the photoluminescence behaviour of CuLaSe2 quantum dots

Published: March 2024

AbstractIn this study, CuLaSe2 and ZnCuLaSe2 quantum dots (QDs) with a mean size of ~4 nm were synthesized and characterized, and their temperature‐dependent photoluminescence (PL) properties were studied in the temperature range from 90 to 300 K for the first time. The results show that the obtained QDs were spherical and revealed excitonic band gaps. The PL intensity for both types of materials decreased when increasing the temperature to 300 K, which was attributed to the nonradiative relaxation and thermal escape mechanisms. As the temperature was increased, the PL linewidths broadened, and PL peak energies were red shifted for both types of QDs due to the exciton–phonon coupling and lattice deformation potential mechanisms. In addition, we found that as the temperature was decreased, the PL spectrum of ZnCuLaSe2 QDs contained two extra components, which could be attributed to the shallow defect sites (low energy peak) and the crystal phase transition process (high energy peak). The spectrum of CuLaSe2 QDs contained one extra component, which could be attributed to the crystal phase transition process.
Gender diversity and environmental activism: Gender discrimination or socialisation?
Authors: Yu Jialing , Liu Yang Stephanie 
Published: March 2024

AbstractThis paper empirically investigates the association between different executive roles taken by women and environmental shareholder activism at the shareholder proposal filing stage and the withdrawal stage. Building on gender socialisation theory and the managerial power perspective, and with 2350 firm‐year observations from Standard and Poor's (S&P) 1500 companies in the United States for the years 2010–2018, we find that environmental activists display a greater propensity to target firms led by women CEO–Chairs at the shareholder proposal filing stage, while no significant preference is observed towards general women directors or CEOs. To explore the rationale behind this preference—whether it stems from gender discrimination or socialisation—we extend our investigation to the withdrawal stage and identify a significantly positive influence from both women CEOs and CEO–Chairs, with the influence from CEO–Chairs being more pronounced. We postulate that both the managerial power and women's socialised traits (such as being more altruistic, collaborative and communicative) are plausible explanations for this gender effect, and women without substantial legitimate power in environmental matters are unable to exert a significant impact.
FACULTY OF PSYCOLOGY OF MÁLAGA, SPAIN. COMPOSITE STEEL‐CONCRETE STRUCTURE IN A SINGULAR BUILDING
Authors: Gómez Javier , Sáez Isabel , Bernabeu Alejandro 
Published: March 2024

AbstractThe paper presents the design and construction of the new Faculty of Psychology in Málaga, Spain, by LLPS Architects. The project offers an interesting example of the relation between structure and architecture, based on a singular configuration of a composite steel‐concrete structure, which responds in a coherent and attractive way to the architectural configuration. The building is formed by a massive and compact three‐heights volume of 90x100 m. Two main architectural features determine the structural configuration: the interior courtyards, that measure 18x3 m., and are disposed in staggered arrangement to allow the entrance of natural light; and the cantilever of the above‐ground volume, that creates a large column‐free covered space.

Published: March 2024

AbstractIn recent years, the focus on reducing the environmental impact of construction has shifted from operational carbon emissions to embodied carbon or materials due to the constant decarbonization of the energy sector. This paper compares the life‐cycle assessment (LCA) of a collective housing building in Portugal, examining four structural solutions: composite steel and concrete, light steel framing, prefabricated reinforced concrete, and cross‐laminated timber load‐bearing walls. This study aims to aid construction professionals in making environmentally informed decisions by comparing design options composed of different materials and highlighting potential improvements in environmental performance.
STEEL PLATE GIRDERS: RESIDUAL STRESSES FROM THE MANUFACTURING PROCESS
Authors: Ferreira Sebastião Gomes , Nascimento Sérgio , Pedro José Oliveira 
Published: March 2024

AbstractThe manufacturing process of steel plate girders generates residual stresses and geometrical imperfections in the flange and web plates that constitute them. These imperfections must respect the manufacturing tolerances that are presented in the regulation. In the present work several stages of the manufacturing process are studied, being these the thermal cutting of the plates, the assembling of the beam and the flange‐web welding process. This work is also accompanied by several results in terms of residual stresses and geometric imperfections of an experimental study and is made the confrontation of those results with the theoretical information available on the prEN 1993‐1‐14 and with the results obtained by numerical models that simulate the thermal processes of the plates cutting and welding.

Authors: Fiorini Cesare , Craveiro Hélder D. , Santiago e Aldina C. 
Published: March 2024

AbstractFires at the Wildland‐Urban Interface (WUI) have a strong detrimental impact on the built environment. This study evaluates the effect of fire in the WUI on steel sandwich panels in a prescriptive fire field experience. The heat transfer mechanisms are obtained using a computational fluid dynamic (CFD) simulation, more specifically the adiabatic surface temperatures (AST) of the structure. The ASTs were applied in a finite element model (FEM) as boundary conditions in the thermal field in order to quantify the heat transfer processed by the FEM. In conclusion, it is identified which area of the structure is most affected due to the temperatures in the panels.
A Halogen Bonding [2]Rotaxane Shuttle for Chloride‐Selective Optical Sensing
Authors: Tay Hui Min , Docker Andrew , Taylor Andrew J. , Beer Paul D. 
Published: March 2024

AbstractThe first example of a [2]rotaxane shuttle capable of selective optical sensing of chloride anions over other halides is reported. The rotaxane was synthesised via a chloride ion template‐directed cyclisation of an isophthalamide macrocycle around a multi‐station axle containing peripheral naphthalene diimide (NDI) stations and a halogen bonding (XB) bis(iodotriazole) based station. Proton NMR studies indicate the macrocycle resides preferentially at the NDI stations in the free rotaxane, where it is stabilised by aromatic donor‐acceptor charge transfer interactions between the axle NDI and macrocycle hydroquinone moieties. Addition of chloride ions in an aqueous‐acetone solvent mixture induces macrocycle translocation to the XB anion binding station to facilitate the formation of convergent XB⋅⋅⋅Cl− and hydrogen bonding HB⋅⋅⋅Cl− interactions, which is accompanied by a reduction of the charge‐transfer absorption band. Importantly, little to no optical response was induced by addition of bromide or iodide to the rotaxane, indicative of the size discriminative steric inaccessibility of the interlocked cavity to the larger halides, demonstrating the potential of using the mechanical bond effect as a potent strategy and tool in chloride‐selective chemo‐sensing applications in aqueous containing solvent environments.

Published: March 2024

AbstractTwo phenothiazine‐based electroactive compounds were synthesized by Buchwald‐Hartwig cross‐coupling reaction. The compounds consist of pyridine‐ or benzonitrile accepting moiety and phenothiazine donor fragments linked through tertiary amino linkage. The resulting electroactive compounds showed high thermal stability with 10 % weight loss temperatures of 270 and 308 °C. Both the compounds showed reversible oxidation after repeated scans of cyclic voltammetry. Experimental results in combination with the outcomes of TD‐DFT calculations, were employed to examine the emission nature of the target compounds. By demonstrating the correct choice of acceptor moiety and linking topology, the synthesized compounds were found to be emitters exhibiting efficient RTP. With emission lifetime reaching 26.04 ms and spin‐orbit coupling value of the triplet states with the singlet ground state of 18.72 cm−1, the radiative recombination of the triplet state is ensured. Having lifetimes of 26 ms and strong sensitivity to oxygen, the benzonitrile‐containing phenothiazine derivative demonstrated fast oxygen response with the quenching constant of 4.97*10−4 ppm−1 at low oxygen concentrations that is comparable to the corresponding characteristics of reported RTP‐based sensors.
Comparison of Vinyldimethylaniline and Indolizine Donor Groups on Si‐Substituted Xanthene Core Shortwave Infrared Fluorophores

Published: March 2024

AbstractSmall organic molecules absorbing and emitting in the shortwave infrared (SWIR, 1000–2000 nm) region are desirable for biological imaging applications due to low auto‐fluorescence, reduce photon scattering, and good tissue penetration depth of photons which allows for in vivo imaging with high resolution and sensitivity. Si‐substituted xanthene‐based fluorophores with indolizine donors have demonstrated some of the longest wavelengths of absorption and emission from organic dyes. This work seeks to compare an indolizine heterocyclic nitrogen with dimethyl aniline nitrogen donors on otherwise identical Si‐substituted xanthene fluorophores via optical spectroscopy, computational chemistry and electrochemistry. Three donors are compared including an indolizine donor, a ubiquitous dimethyl aniline donor, and a vinyl dimethyl aniline group that keeps the number of π‐bonds consistent with indolizine. Significantly higher quantum yields and molar absorptivity are observed in these studies for a dimethylamine‐based donor relative to a simple indolizine donor absorbing and emitting at similar wavelengths (~1312 nm emission). Substantially longer wavelengths are obtainable by appending aniline‐based groups to the indolizine donor (~1700 nm) indicating longer wavelengths can be accessed with indolizine donors while stronger emitters can be accessed with anilines in place of indolizine.
On the analytical modeling of fractal memelement and inverse memelement
Authors: Banchuin Rawid 
Published: March 2024

SummaryIn this work, an improved analytical model of fractal memelement in which the pinched point shifting has been considered and the original analytical model of fractal inverse memelement have been proposed. These fractal circuit elements are the memelement, and inverse memelement operates based on the principle of electromagnetic in fractal time/space, which must be applied whenever the current flows through fractal media. These models are important because these memory elements can be realized based on the porous material, which is a fractal media. In addition, they can employ self‐similarity, which is hard to be simulated by using the traditional models. This is because such self‐similarity can be well explained by the fractal set‐based model, yet those traditional models are based on the set of real values. Therefore, for deriving the proposed models, the fractal calculus, which is oriented to the fractal set, has been adopted as the mathematical basis. From the analytical and numerical analyses based on the derived models, it has been found that both memelement and inverse memelement can retain their unique frequency characteristics despite being operated based on the abovementioned principle. In addition, their input–output relationships are mathematically differentiable albeit the inputs and outputs themselves are not.

AbstractBackgroundInflammatory bowel diseases (IBDs) pose significant challenges in terms of treatment non‐response, necessitating the development of novel therapeutic approaches. Although biological medicines that target TNF‐α (tumour necrosis factor‐α) have shown clinical success in some IBD patients, a substantial proportion still fails to respond.MethodsWe designed bispecific nanobodies (BsNbs) with the ability to simultaneously target human macrophage‐expressed membrane TNF‐α (hmTNF‐α) and IL‐23. Additionally, we fused the constant region of human IgG1 Fc (hIgG1 Fc) to BsNb to create BsNb‐Fc. Our study encompassed in vitro and in vivo characterization of BsNb and BsNb‐Fc.ResultsBsNb‐Fc exhibited an improved serum half‐life, targeting capability and effector function than BsNb. It's demonstrated that BsNb‐Fc exhibited superior anti‐inflammatory effects compared to the anti‐TNF‐α mAb (infliximab, IFX) combined with anti‐IL‐12/IL‐23p40 mAb (ustekinumab, UST) by Transwell co‐culture assays. Notably, in murine models of acute colitis brought on by 2,4,6‐trinitrobenzene sulfonic acid（TNBS) and dextran sulphate sodium (DSS), BsNb‐Fc effectively alleviated colitis severity. Additionally, BsNb‐Fc outperformed the IFX&UST combination in TNBS‐induced colitis, significantly reducing colon inflammation in mice with colitis produced by TNBS and DSS.ConclusionThese findings highlight an enhanced efficacy and improved biostability of BsNb‐Fc, suggesting its potential as a promising therapeutic option for IBD patients with insufficient response to TNF‐α inhibition.Key points
A bispecific nanobody (BsNb) was created to target TNF‐α and IL‐23p19, exhibiting high affinity and remarkable stability.
BsNb‐Fc inhibited the release of cytokines in CD4+T cells during co‐culture experiments.
BsNb‐Fc effectively alleviated colitis severity in mouse model with acute colitis induced by DSS or TNBS, outperforming the IFX&UST combination.
Wi‐Fi 6‐based home area network for demand response in smart grid

Published: March 2024

SummaryThe past decade has brought prolific developments to power systems that range from large‐scale renewable integration to digital twins. Modern power systems consist of highly variable generation clusters. Hence, monitoring and prediction of power generation has become a vital part of today's power systems. On the other hand, detailed real‐time information of power usage is also a key parameter for the control algorithms used for the demand side management. With this information flow, power systems become smart grids which offer improved service and enable many advanced operations. In this regard, the home area network (HAN), which collects the power consumption/generation of household devices, plays a key role. So far, a number of technologies such as ZigBee, Z‐Wave, and Power Line Communication (PLC) have been considered for the HAN. Yet, widely used wireless local area network (WLAN) technology, Wi‐Fi, was not identified as a prominent candidate due to the limitations in its latency and reliability. However, with the introduction of the IEEE 802.11ax standard, Wi‐Fi 6 was developed, and it demonstrates guaranteed latency and reliability for its users. Thus, with its widespread deployment in households, Wi‐Fi is becoming a natural candidate for HAN. In this article, we present a comprehensive HAN protocol based on Wi‐Fi 6 which can achieve guaranteed latency and reliability for HAN users. The results show that when an efficient resource allocation mechanism is in place, using Wi‐Fi for HAN does not adversely affect the other Wi‐Fi users in the normal WLAN.
