The impact of environmental sustainability on willingness to invest in startups: A survey among private investors
Authors: Voß Lasse , Cordes Henning , Lueg Rainer 
Published: November 2024

AbstractThis study investigates the impact of environmental sustainability on willingness to invest (WTI) in startups vs. established companies. Using data from a survey among private investors, we compare measures of WTI and the perceived return–risk ratio (RRR) for both environmentally sustainable and non‐environmentally sustainable startups and established companies. The results indicate that environmental sustainability significantly and positively influences WTI for both startups and established companies, with a notably stronger effect for startups. Non‐environmental sustainability significantly decreases WTI. Environmental sustainability has a significantly positive impact on the perceived RRR for both startups and established companies, although startups are rewarded more than established companies for environmentally sustainable practices. This highlights that entrepreneurs have a financial incentive to prioritize environmental impact, and the demand for environmental sustainability can provide startups with an advantage in capital raising. This research contributes to the limited literature regarding sustainable entrepreneurship and environmental sustainability's specific impact on WTI.

AbstractIn this study, veratrylidenehydrazide was isolated from Wedelia biflora, and compounds (1a, 2a, and 3a–j) were synthesised to evaluate their larvicidal and antifeedant activities. Veratrylidenehydrazide 1a was verified using GC‐MS. The veratrylidenehydrazide analogues 2a and 3a–j were synthesised via a condensation method with yield range 71%–92%. The compounds (1a, 2a, and 3a–j) were synthesised and characterised through FT–IR, 1H NMR, 13C NMR, mass spectrometry, and elemental analysis. Veratrylidenehydrazide 1a was verified using GC‐MS analysis. Natural veratrylidenehydrazide compound 1a and the synthesised veratrylidenehydrazide analogues (2a, 3a–j) were screened for larvicidal activity against Culex quinquefasciatus. The larvicidal activity of compound 3g was found to be highly active, while low toxicity was observed against Oreochromis mossambicus nontarget aquatic species compared to natural veratrylidenehydrazide. Compound 3g exhibited a higher binding affinity (−8.8 kcal/mol) compared to standard of temephos (−4.5 kcal/mol), equipotential binding affinity against permethrin (−9.1 kcal/mol), and diflubenzuron (−8.5 kcal/mol). Lead molecules have larvicidal properties, and their use as insecticides makes them important.

AbstractThe discovery of ferroelectricity in hafnia‐based materials has revitalized interest in realizing ferroelectric field‐effect transistors (FeFETs) due to its compatibility with modern microelectronics. Furthermore, low‐temperature processing by atomic layer deposition offers promise for realizing monolithic three‐dimensional (M3D) integration toward energy‐ and area‐efficient computing paradigms. However, integrating ferroelectrics with channel materials in FeFETs for M3D integration remains challenging due to the dual requirement of a high‐quality ferroelectric‐channel interface and low‐power operation, all while maintaining back‐end‐of‐line (BEOL)‐compatible fabrication temperatures. Recent studies on 2D semiconductors and metal oxide channels highlight these challenges. Polycrystalline silicon (poly‐Si), a channel material long integrated into the semiconductor industry, presents a promising alternative; however, its high fabrication temperature has hindered its applications to M3D integration. To overcome this challenge, we demonstrates a BEOL‐compatible FeFET platform using poly‐Si channels fabricated via locally‐confined laser thermal processing and hafnia‐based ferroelectrics by low‐temperature atomic layer deposition with wafer‐scale uniformity. The local nature of the laser processing mitigates the trade‐off between the high‐temperature crystallization for the quality of the interface and BEOL thermal budget constraints. The laser‐processed FeFETs boast the largest effective memory widow for all BEOL‐compatible FeFETs. Moreover, the fabricated FeFETs are integrated into wafer‐scale synaptic arrays for neuromorphic computing, achieving record‐high energy efficiency. Therefore, this work establishes a promising BEOL‐compatible FeFET materials platform toward M3D integration.

Published: November 2024

AbstractHigh‐performance fiber‐reinforced composite materials demonstrate great potential for manufacturing diaphragms in human‐engineered acoustic loudspeakers. However, the notable scarcity of high‐quality fibers and the uncontrollable nature of the diaphragm structure limit the production of high‐quality sound that conforms to human hearing. In this study, a novel composite diaphragm material is devloped by integrating the swelling carboxymethyl cellulose microfiber (CMF) with the hot‐melted sheath‐core fiber (SCF) based on the “interpenetrating polymeric network” (“IPN”) strategy. Simulation methods and Flory‐Huggins theory are applied to explain the mechanism of fiber‐structure‐property interaction in composite diaphragm materials. Owing to the distinct microstructure, this bio‐based diaphragm material shows superior mechanical characteristics, including low density (≈0.92 g cm−3), high tensile strength (≈235 MPa), and high modulus (≈9.73 GPa). Moreover, the loudspeaker mounted with bio‐based diaphragm material exhibits enhanced sensitivity (≈82.6 dB) and stable performance across a broad frequency spectrum. This study not only elucidates the multiphysics working principles of loudspeakers but also establishes a crucial connection between the physical properties of diaphragms and loudspeaker performance. It opens up new avenues for the design of high‐performance bio‐based loudspeaker diaphragms in high‐fidelity (Hi‐Fi) acoustic devices.

AbstractProducing hydrogen via seawater electrolysis is pivotal for addressing both energy and environmental crises. An industrial‐current‐density electrocatalyst consisting of Mo‐doped FeCoP nanorods decorated with MnOx nanosheets is elaborately designed and grows in situ on nickel foam forming hierarchical Mo‐FeCoP@MnOx/NF (M‐FCP@MnOx/NF) for seawater electrolysis. Density functional theory calculations demonstrate that MnOx species remarkably reduce the adsorption capacity of Cl−, which enhances the corrosion resistance and selectivity of M‐FCP@MnOx/NF during seawater electrolysis. Moreover, incorporating high‐valence Mo species forms a superficial electrostatic layer on electrocatalysts to repel Cl−. Owing to its enhanced double protection mechanism and unique self‐healing characteristics, M‐FCP@MnOx/NF requires overpotentials of only 209 mV (HER) and 270 mV (OER) to reach a current density of ≈1.0 A cm−2 and maintains stable operation over 120 h during alkaline electrolysis of seawater. The colorimetric analysis indicates negligible ClO− production post stability test, indicating that the OER selectivity approaches 100%.
Intermetallic Compounds for Hydrogen Storage: Current Status and Future Perspectives
Authors: Paul Amrit Raj , Mehla Sunil , Bhargava Suresh 
Published: November 2024

AbstractIntermetallic compounds are an emerging class of materials with intriguing hydrogen activation and storage capabilities garnering attention for their application in low‐temperature hydrogen storage and metal hydride batteries. However, none of the existing intermetallic compounds have met the gravimetric hydrogen storage capacity target of 5.5 wt.%. Some A2B‐type intermetallic compounds, like Mg2Ni, Mg2Co, and Mg2Fe, approach this target but require high temperatures for hydrogen desorption limiting their use in low‐temperature hydrogen storage and automotive applications. Conversely, some intermetallic compounds like ZrV2 and LaNi5, exhibit hydrogen desorption at ambient conditions but with comparatively lower hydrogen storage capacities. This review article provides a comprehensive account of the different types of intermetallic compounds, their synthesis using different solidification‐based and solid‐state diffusion‐based approaches, and their metallurgical and structural properties. It examines the complex interdependencies between the structural parameters of intermetallic compounds and hydrogen storage performance. A definitive but non‐linear correlation is identified between void volume and gravimetric hydrogen storage capacities while lattice structure, evolution of lattice structure with hydrogen absorption, enthalpy of hydride formation, and hydrogen activation reactivities of intermetallic compounds are identified as critical parameters governing hydrogen storage performance.
JumpBackHash: Say Goodbye to the Modulo Operation to Distribute Keys Uniformly to Buckets
Authors: Ertl Otmar 
Published: November 2024

ABSTRACTIntroductionDistributed data processing and storage systems require efficient methods to distribute keys across buckets. While simple and fast, the traditional modulo‐based mapping is unstable when the number of buckets changes, leading to spikes in system resource utilization, such as network or database requests. Consistent hash algorithms minimize remappings but are either significantly slower, require floating‐point arithmetic, or are based on a family of hash functions rarely available in standard libraries. This work introduces JumpBackHash, a consistent hash algorithm that overcomes those shortcomings.MethodologyJumpBackHash applies the concept of active indices borrowed from consistent weighted sampling, which inherently leads to consistency. It generates the active indices in reverse order, which avoids floating‐point operations, enables the minimization of consumed random values and the use of a standard pseudorandom generator, and finally leads to a very efficient algorithm.ResultsTheoretical analysis shows that JumpBackHash has an expected constant runtime. The expected value and the variance of the number of consumed random values perfectly agree with the experiments. Empirical tests also confirm the consistency.ConclusionJumpBackHash offers a fast and efficient solution for uniformly distributing keys across buckets in distributed systems. Its simplicity, performance, and the availability of a production‐ready Java implementation as part of the Hash4j open source library make it a viable replacement for the modulo‐based approach for improving assignment and system stability.

ABSTRACTIn this paper, an innovative damper made of low yield point (LYP) steel compound of double corrugated plate and flange plates to form an I‐shaped damper was considered parametrically and numerically. This damper pertain to easy fabrication and replacement after a severe earthquake. The proposed damper is expected to yield while elements outside the damper remain elastic. Consequently, it acts as a ductile fuse that was confirmed in this study. Results indicated that changing the damper from conventional steel to LYP steel improves the damper's performance. Because dampers with the same exhibited different responses, classification of the damper response based on the is not approritae. Of course, considering the fact that it has shear behavior with can be used in the initial design, but it is an incomplete criterion. Also, for dampers with , the ultimate strength is increased related to the from 2.64 to 4.50 times whereas for and is reached 1.35 to 3.84 times and 1.34 to 3.80 times, respectively. It confirms that on the , the most effective on the ultimate strength is obtained by changing the A36 steel to LYP steel. It should be noted that by increasing the by two to four times, the energy dissipation is enhanced 1.44 to 5.64 times for LYP dampers and 1.15 to 2.02 times for A36 dampers.

AbstractIn this paper the Eringen–Cattaneo–Christov–Straughan linearized model is investigated, studying for it in particular: (i) the well‐posedness in Hadamard's sense of the related initial‐boundary value problem, by resorting to the semigroup theory; and (ii) the type of decay the solutions are subject to. This study contributes to strengthening the theoretical basis of a recent model capable of describing thermoporoacoustic phenomena.
Looking for Dark Matter Credit: Exploring Notarial Credit Markets in Antwerp and Its Surroundings ca. 1835
Authors: Peeters Ruben , van Kooten Rogier 
Published: November 2024

AbstractThis chapter investigates the notarial credit markets in Antwerp and its environs during the early nineteenth century, with a focus on their structure, functioning, and flows. Prior to the twentieth century, notarial credit markets played a significant role in supplying substantial investment capital to both firms and households. However, knowledge regarding these markets, particularly outside of France, is limited. Leveraging a newly compiled dataset of notarized loans, we employ descriptive statistics, geographical mapping, and social network analysis to analyze the dynamics of the credit market. Our findings indicate a sizable and expansive urban credit market, wherein affluent creditors dominated, yet the middling classes also actively participate as debtors. Credit transactions primarily circulated within the city or its surrounding countryside, while the city was well connected to surrounding municipalities and more distant large cities. Contrasting with village notaries, those situated in Antwerp showed a broader geographical reach, engaging in credit transactions not only within Belgium but also extending internationally. This research contributes to a nuanced understanding of notarial credit markets beyond the scope of nineteenth-century France.
Credit and Social Networks in Late Fourteenth-Century Tyrol: The Village of Laas
Authors: Nicolussi-Köhler Stephan 
Published: November 2024

AbstractThis paper delves into the functioning of credit markets during the late fourteenth century in Tyrol, using a notarial register from a rural area and applying a social network analysis approach. Particular focus is directed toward the individuals involved in the credit market within the village of Laas. The findings indicate that credit transactions, typically backed by collaterals, predominantly circulated within the confines of the local community and its immediate vicinity, spanning roughly a 50-kilometer radius, as interregional capital markets were relatively underdeveloped. Both the notary and the village officeholders played critical roles in organizing and mediating issues arising from asymmetric information within the credit market.
Moneychangers and the Local Credit Market in Late Renaissance Florence. A Social Network Analysis
Authors: Pompermaier Matteo 
Published: November 2024

AbstractThis chapter studies the structure and functioning of the interpersonal credit network in fifteenth-century Florence, focusing particularly on intermediation. To this end, the research centers on a specific professional group, the moneychangers. They were trained accountants and among the few individuals in the city with ready cash, which allowed them to be very active in the credit market. The sources show that they were not only lenders, but also intermediaries and guarantors. The chapter uses social network analysis (SNA) to investigate the main characteristics of the credit network and uses a multilevel algorithm to identify and study the communities that compose it. The analysis confirms the strength of professional and geographical homophily in network formation. Moreover, it suggests that moneychangers might have had an important bridging role in the Florentine credit market and highlights the ways through which they linked various communities of the network with each other. The paper confirms quantitatively and qualitatively the important contribution of moneychangers to the efficiency of the local credit market—identified here as the capacity of the market to match debtors and creditors.

Published: November 2024

AbstractWe present a study on femtosecond laser treatment of amorphous hydrogen-containing carbon coatings (a-C:H). The coatings were deposited on silicon wafers by a plasma-assisted chemical vapour deposition (PA-CVD), resulting in two different types of material with distinct properties (referred to as “absorbing” and “semi-transparent” coatings in the following). The samples were laser-treated with single fs-laser pulses (800 nm center wavelength, 35 fs pulse duration) in the ablative regime. Through a multi-method approach using topometry, Raman spectroscopy, and spectroscopic imaging ellipsometry, we can identify zones and thresholds of different fluence dependent effects and have access to the local dielectric function. The two coating materials react significantly different upon laser treatment. We determined the (non-ablative) modification threshold fluence for the absorbing coating as $$3.6\times {10}^{-2}$$

Jcm−2 and its ablation threshold as 0.22 Jcm−2. The semi-transparent coating does not show such a low-fluence modification but exhibits a characteristic interference-based intra-film ablation mechanism with two distinguishable ablation thresholds at 0.25 and 0.28 Jcm−2, respectively. The combination of tailored layer materials and correlative imaging spectroscopic methods delivers new insights into the behaviour of materials when treated with ultrashort-pulse laser radiation.

Abstract
Objectives
This study aimed to assess the prognostic value of routinely collected laboratory parameters, specifically lactate, troponin-T, and CK-MB, in predicting mortality in patients with surgically treated endocarditis. Additionally, the study evaluated the effectiveness of two mortality scores, EuroSCORE II and ACEF II Score, in this clinical context.

Methods
We retrospectively analyzed data from 130 patients diagnosed with endocarditis who underwent surgery at a single tertiary center over nine years. The study utilized preoperative mortality scores and laboratory parameters collected within the first 24 h post-surgery. Statistical analyses included AUROC curves, Kaplan–Meier survival analyses, and correlation analyses to determine predictive values and associations with patient outcomes.

Results
Among the 130 patients, 28 (21.5%) died within one year post-surgery. Elevated postoperative lactate levels were significantly associated with increased short- and long-term mortality, with AUROC values indicating strong predictive capability. The ACEF II Score also demonstrated significant predictive value for mortality at various time points, outperforming EuroSCORE II. Higher lactate levels and ACEF II Scores correlated with increased hazard ratios for mortality. Kaplan–Meier analyses revealed significant survival differences based on lactate and ACEF II Score thresholds.

Conclusion
Postoperative lactate levels and the ACEF II Score are robust predictors of mortality in patients undergoing cardiac surgery for endocarditis. Integrating these parameters into clinical practice can enhance risk stratification and guide therapeutic decisions, improving patient outcomes through personalized care. Further studies are needed to validate these findings across diverse populations and explore additional biomarkers for refined predictive accuracy.
