Ground tire rubber and coffee silverskin as sustainable fillers in EPDM compounds for rubber‐to‐steel bonded systems in roofing applications
Authors: Bragaglia Mario , Paleari Lorenzo , Nanni Francesca 
Published: March 2024

AbstractIn this paper two waste fillers, namely ground tire rubber (GTR) and coffee silverskin (CSS, a waste bio‐product from the coffee‐making process), have been used to produce sustainable ethylene‐propylene‐diene monomer (EPDM) rubber compounds vulcanized on steel sheets to fabricate rubber‐to‐steel bonded systems for industrial roofing applications. The compounds have shown good mechanical performances, with elastic moduli in the range of 13–16 MPa, tensile strength of 13–20 MPa and elongation at break >400%, and strong adhesion to the metal substrate. Moreover, the rubber‐to‐steel bonded systems present good sound insulation properties (mean sound transmission loss [STL] of 39 dB and noise level reduction in simulated hailstones impact tests of 62 dB with respect to bare steel 73 dB). Accelerated UV‐ and thermal‐aging tests have shown excellent adhesion of the compounds to the metal substrate with the CSS acting as an antioxidant agent preventing excessive polymer degradation. The selected waste‐derived materials result in promising fillers for more sustainable rubber compounds.Highlights

AbstractThe combined application of ultrasound (US) and plasma microbubble (PMB) is a promising technology against glioblastoma (GBM). Here, we determined the effects of US and PMB (alone and combined) on U‐251 MG GBM and A431 epidermoid carcinoma spheroids under different conditions. The synergistic treatment of US‐ and PMB‐induced tumor sphere cell death in a time‐, dose‐, treatment frequency‐, and reactive oxygen species dependent manner, while multiple treatments augmented this effect. Synergistic treatments significantly reduced three‐dimensional GBM spheroid regrowth and cell proliferation while inducing cytotoxicity, spheroid shrinkage, and damage to the tumor microenvironment. PMB‐induced cytotoxicity throughout the tumor sphere, likely via long‐lived reactive oxygen and nitrogen species (H2O2, NO2−, and NO3−) and other reactive species.
Event‐triggered differential private distributed fusion estimation for sensor networks with unknown cross‐correlations

Published: March 2024

AbstractRecently, preserving privacy and reducing energy consumption become important concerns of sensor networks. However, existing privacy‐preserving estimation methods cause many needless data transmissions, which results in energy waste. Besides, these methods generates fusion estimates with heavy computational burdens, due to needing calculating cross‐covariance matrices of each pair of local estimation errors. Worse still, these cross‐covariances are often unavailable in actual sensor networks. In view of these problems, a novel framework of event‐triggered (ET) differential private distributed fusion estimation is proposed. Within this framework, an ET mechanism is designed to schedule transmissions of local estimates for reducing communication consumptions. Then, with using local perturbation mechanism, conditions for achieving differential privacy and dealing with eavesdroppers which can eavesdrop and fuse local estimates are provided. Based on covariance intersection fusion rule, an ET differential private fusion method is developed, which can guarantee fusion results uniformly stable in spite of completely unknown cross‐covariances. Finally, simulation results verify that the proposed method can preserve privacy and reduce communication consumptions without using cross‐covariances, at the cost of only slight decline of estimation performance.

AbstractRecently, aqueous zinc ion batteries (AZIBs) with the superior theoretical capacity, high safety, low prices, and environmental protection, have emerged as a contender for advanced energy storage. However, challenges related to cathode materials, such as dissolution, instability, and structural collapse, have hindered the progress of AZIBs. Here, a novel AZIB is constructed using an oxidized 2D layered MnBi2Te4 cathode for the first time. The oxidized MnBi2Te4 cathode with large interlayer spacing and low energy barrier for zinc ion diffusion at 240 °C, exhibited impressive characteristics, including a high reversibility capacity of 393.1 mAh g−1 (0.4 A g−1), outstanding rate performance, and long cycle stability. Moreover, the corresponding aqueous button cell also exhibits excellent electrochemical performance. To demonstrate the application in practice in the realm of flexible wearable electronics, a quasi‐solid‐state micro ZIB (MZIB) is constructed and shows excellent flexibility and high‐temperature stability (the capacity does not significantly degrade when the temperature reaches 100 °C and the bending angle exceeds 150°). This research offers effective tactics for creating high‐performance cathode materials for AZIBs.

AbstractDeveloping new approaches amenable to the measurement of neuronal physiology in real‐time is a very active field of investigation, as it will offer improved methods to assess the impact of diverse insults on neuronal homeostasis. Here, the development of an in vitro bio platform is reported which can record the electrical activity of cultured primary rat cortical neurons with extreme sensitivity, while simultaneously tracking the localized changes in the pH of the culture medium. This bio platform features passive vertical nanoprobes with ultra‐high signal resolution (several mV amplitude ranges) and Chem‐FinFETs (pH sensitivity of sub‐0.1 pH units), covering an area as little as a neuronal soma. These multi‐sensing units are arranged in an array to probe both chemically and electrically an equivalent surface of ≈ 0.5 mm2. A homemade setup is also developed which allows recording of multiplexed data in real‐time (10 ps range) from the active chem‐sensors and passive electrodes and which is used to operate the platform. Finally, a proof‐of‐concept is presented for a neuro‐relevant application, by investigating the effect on neuronal activity of Amyloid beta oligomers, the main toxic peptide in Alzheimer's Disease, which reveals that exposure to amyloid beta oligomers modify the amplitude, but not the frequency, of neuronal firing, without any detectable changes in pH values along this process.

Published: March 2024

AbstractElectroluminochromic (ELC) materials have garnered significant research interest because of their potential applications in lighting, displaying, and sensing. These materials exhibit reversible modulation of photoluminescence under low‐voltage stimuli. Here five phosphorescent iridium(III) complexes are reported featuring viologen‐substituted 2‐phenylpyridine (Vppy) ligands acting as electroactive components. Four of the complexes are bis‐cyclometalated and coordinated with either neutral bipyridine derivatives or negatively charged 2‐picolinate. The remaining complex is heteroleptic tris‐cyclometalated, containing one Vppy and two 2‐phenylquinoline ligands. Upon photoexcitation, the bis‐cyclometalated complexes exhibit orange to red phosphorescence originating from mixed triplet metal‐to‐ligand charge transfer (3MLCT) and intraligand (3IL) dπ(Ir)/π(Vppy) → π*(Vppy) state, whereas the tris‐cyclometalated complex is non‐emissive due to a low Ir(IV/III) oxidation potential favoring oxidative quenching by the viologen pendants. When the cationic viologens are electrochemically reduced to their neutral form, the bis‐cyclometalated complexes show a remarkable blue‐shift in their phosphorescence maxima due to increased energy levels of the Vppy molecular orbitals. In the case of the tris‐cyclometalated complex, reduction of the viologen groups interrupts the quenching process, leading to a luminescence turn‐on. These complexes are used to develop ELC devices, which exhibit reversible luminescence response in terms of color or on‐off switching under a low voltage of 2 V.

Published: March 2024

AbstractThis study examines the effects of annealing process (temperature 50 °C, moisture content of 80%, for 20 h) on physicochemical characteristics (proximate composition, content of resistant starch (RS) and amylose, degree of starch digestibility, shape and size of starch granules, crystallinity, and starch gelatinization profile) of corn flour and corn starch. Two stages of experiment are as follows: 1) verifying the results of the meta‐analysis of corn starch and flour modification by annealing method and 2) analyzing their physicochemical properties. As a result, annealing significantly improves RS content in both groups, reaching 14.18% in annealed corn flour (AF) (compared to 3.27% in native corn flour (NF)) and 21.87% in annealed corn starch (AS) (compared to 3.82% in native corn starch (NS)). The present work also confirms that the treatment unaltered birefringence properties of all samples. Moreover, pasting properties of corn starch and flour demonstrate remarkable changes. The peak viscosity of AS and NS is higher than AF and NF. In addition, gelatinization seems to occur at similar temperature, but needs extra time for starting gelatinization. XRD analysis reveals A‐type crystalline for all samples, while FTIR analysis evidenced that annealing process alters the regions of amorphous and crystalline.
Elias Magnus Fries's fungus exsiccatiScleromyceti Sueciae: New light on the obscure “fascicle nine”
Authors: Karakehian Jason M. , Pfister Donald H. , Miller Andrew N. 
Published: March 2024

AbstractElias Magnus Fries's fungus exsiccatiScleromyceti Sueciaedocuments specimens cited in several of Fries's publications that are now considered sanctioning works in the nomenclature and taxonomy of several groups of fungi. The first eight fascicles of the first edition of theScleromyceti Sueciaewere issued periodically during the years 1819–1822. Each fascicle was issued as a bound booklet that included, among other information, a printed title page with a date, and an index followed by 30–40 specimens. A ninth fascicle that concluded the first edition was issued without a date. Scholars of theScleromyceti Sueciaeinferred an approximate date of issuance of mid‐1825 based on Fries's correspondence, but they were uncertain whether fascicle nine was issued as a booklet or on loose sheets. In addition, the location of the printed index to fascicle nine that they studied was unclear. We obtained images of a complete, original copy of fascicle nine from the collections of the Natural History Museum of Denmark of the University of Copenhagen. This copy proves that fascicle nine was issued as a bound booklet like the previous eight fascicles and contained a printed index and printed specimen labels. Because of the apparent rarity of a complete, original copy of fascicle nine, we describe the copy at the Natural History Museum of Denmark and provide images of the index. We discuss potential problems in typifying names from material issued in theScleromyceti Sueciaesecond edition. Using an example from fascicle nine, we discuss Fries's omissions, errors, and lapses in citing specimens.
Synergistic enhancement of toughness and flame retardation for cyanate ester composites through hyperbranched polyborosiloxane

Published: March 2024

AbstractExcellent flame resistance is supposed to be taken into consideration for electronic packaging materials due to the spontaneous combustion of short circuits, except for good mechanical and dielectric properties. Herein, a hyperbranched polyborosiloxane (HPSiB) flame retardant was synthesized via a simple one‐pot transesterification as a multifunctional additive for cyanate ester (CE) resin. The HPSiB with many active terminals features good compatibility with the resin matrix, while catalyzing the curing reaction that conducts at a lower temperature. With as little as 2 wt% HPSiB incorporated, the HPSiB/bisphenol A cyanate ester (BADCy) resin achieves a UL‐94 V0 rating and 32.4% LOI value, and its peak heat release and total smoke production are simultaneously reduced. Its flexural strength and impact strength were significantly enhanced by 30.0% and 85.4%. Besides, the minimum values of dielectric constant and loss can reach 2.77 and 0.0024 at 10 GHz, which are, respectively, reduced by 7.9% and 88.5%. The integration of unique hyperbranched SiOB backbone of HPSiB with CE crosslinked network was responsible for the enhanced overall performance. This work paves a facile strategy to develop multifunctional flame retardant as a promising candidate for the high‐performance electronic packaging materials.Highlights
A novel hyperbranched polyborosiloxane flame retardant was synthesized.
HPSiB shows good compatibility and catalyzes the curing reaction of CE resin.
HPSiB/CE resin with significantly enhanced flame retardancy was obtained.
Simultaneously high toughness and low dielectric loss were achieved.
Hyperbranched structure containing SiOB chains led to the great enhancement.
Development of thermally assisted OH PLIF temperature measurement method based on a single femtosecond laser

Published: March 2024

AbstractRecently, OH planar laser-induced fluorescence (PLIF) using the broadband, ultrashort femtosecond-duration (fs-duration) and the thermally assisted vibrational transfer in excited state has been investigated in flames. In this present work, we first measured temperature by thermally assisted OH laser-induced fluorescence (TALF) method with a single ultrashort broadband fs laser. In the experiment, the fs excitation of OH at ultraviolet wavelength is followed by fluorescence detection from two different vibrational bands. The ratio of two measured (1–0) and (0–0) band fluorescence is calibrated with calculated temperature using Chemkin PRO PRIMIX. The calibrated results are used in measuring temperature distributions in different laminar flames. It is found that TALF method using the fs laser can detect 2D temperature distribution in the burnt area with high OH fluorescence signal. However, OH chemiluminescence brings inevitable noise at the flame front that the TALF method does not perform well. And because (1–0) band fluorescence is so weak, the noise from the camera sensor and imaging intensifier (I.I.) remains at the measured temperature imaging. In conclusion, quantitative temperature measurement based on OH TALF based on a single broadband, ultrashort fs laser can be applied in laminar flames with high frequency by a simple experiment setup.

AbstractThis contribution presents the first record of the invasive non-native red swamp crayfish Procambarus clarkii (Girard, 1852) in Greece and the Balkans. The crayfish was found during a fish monitoring expedition in the lower reaches of the Vosvozis River, near the city of Komotini, Thrace (northeastern Greece). The finding of P. clarkii in Greece expands the southernmost geographical range of the species in the Balkans and calls for immediate actions in preventing its further expansion to other water bodies and towards strict control of aquarium trade.
Role of albumin infusion in cirrhosis-associated complications
Authors: Heybe Mohamed A. , Mehta Kosha J. 
Published: March 2024

AbstractCirrhosis is an advanced-stage liver disease that occurs due to persistent physiological insults such as excessive alcohol consumption, infections, or toxicity. It is characterised by scar tissue formation, portal hypertension, and ascites (accumulation of fluid in the abdominal cavity) in decompensated cirrhosis. This review evaluates how albumin infusion ameliorates cirrhosis-associated complications. Since albumin is an oncotic plasma protein, albumin infusion allows movement of water into the intravascular space, aids with fluid resuscitation, and thereby contributes to resolving cirrhosis-induced hypovolemia (loss of extracellular fluid) seen in ascites. Thus, albumin infusion helps prevent paracentesis-induced circulatory dysfunction, a complication that occurs when treating ascites. When cirrhosis advances, other complications such as spontaneous bacterial peritonitis and hepatorenal syndrome can manifest. Infused albumin helps mitigate these by exhibiting plasma expansion, antioxidant, and anti-inflammatory functions. In hepatic encephalopathy, albumin infusion is thought to improve cognitive function by reducing ammonia concentration in blood and thereby tackle cirrhosis-induced hepatocyte malfunction in ammonia clearance. Infused albumin can also exhibit protective effects by binding to the cirrhosis-induced proinflammatory cytokines TNFα and IL6. While albumin administration has shown to prolong overall survival of cirrhotic patients with ascites in the ANSWER trial, the ATTIRE and MACHT trials have shown either no effect or limitations such as development of pulmonary oedema and multiorgan failure. Thus, albumin infusion is not a generic treatment option for all cirrhosis patients. Interestingly, cirrhosis-induced structural alterations in native albumin (which lead to formation of different albumin isoforms) can be used as prognostic biomarkers because specific albumin isoforms indicate certain complications of decompensated cirrhosis.
Structures Supporting Virtuous Moral Agency: An Empirical Enquiry
Authors: Vriens Dirk , de Wit Riki A. M. , Groß Claudia 
Published: March 2024

AbstractIt has been argued that organizational structures (the way tasks are defined, allocated, and coordinated) can influence moral agency in organizations. In particular, low values on different structural parameters (functional concentration, specialization, separation, and formalization) are said to foster an organizational context (allowing for relating to the goals and output of the organization, moral deliberation, and social connectedness) that is conducive to moral agency. In this paper, we investigate the relation between the organizational structure and moral agency in the case of a.s.r. (a large Dutch insurance company). While our empirical results fit the thesis that low values on structural parameters positively relate to moral agency, they also refine our understanding of the influence of structural parameters. In particular, our data suggest that the influence of functional concentration not only depends on whether it is low, but also on the type of criterion used for identifying business units; they suggest that the specific organizational context may put a limit to lowering design parameters and points at several non-structural factors that have an influence on the relation between structure and moral agency. In all, the paper contributes to a more detailed understanding of the conditions conducive to moral agency in organizations.

Prym representations of the handlebody group
Authors: Bader Philipp 
Published: March 2024

AbstractLet S be an oriented, closed surface of genus g. The mapping class group of S is the group of orientation preserving homeomorphisms of S modulo isotopy. In 1997, Looijenga introduced the Prym representations, which are virtual representations of the mapping class group that depend on a finite, abelian group. Let V be a genus g handlebody with boundary S. The handlebody group is the subgroup of those mapping classes of S that extend over V. The twist group is the subgroup of the handlebody group generated by twists about meridians. Here, we restrict the Prym representations to the handlebody group and further to the twist group. We determine the image of the representations in the cyclic case.
Higher resonance schemes and Koszul modules of simplicial complexes

Published: March 2024

AbstractEach connected graded, graded-commutative algebraAof finite type over a field$$\Bbbk $$kof characteristic zero defines a complex of finitely generated, graded modules over a symmetric algebra, whose homology graded modules are called the(higher) Koszul modulesofA. In this note, we investigate the geometry of the support loci of these modules, called theresonance schemesof the algebra. When$$A=\Bbbk \langle \Delta \rangle $$A=k⟨Δ⟩is the exterior Stanley–Reisner algebra associated to a finite simplicial complex$$\Delta $$Δ, we show that the resonance schemes are reduced. We also compute the Hilbert series of the Koszul modules and give bounds on the regularity and projective dimension of these graded modules. This leads to a relationship between resonance and Hilbert series that generalizes a known formula for the Chen ranks of a right-angled Artin group.
