Density functional theory study of the styrylbenzoquinoline dyad and the related dibenzoquinolylcyclobutane formed in the [2 + 2] photocycloaddition reaction
Authors: Budyka Mikhail F. 
Published: October 2023

AbstractThe structure and electronic properties of the biphotochromic dyad with two styrylbenzo[f]quinoline photochromes, as well as the corresponding cyclobutane with two benzo[f]quinoline (BQ) substituents, are studied by DFT at the M06‐2X/6‐31G* level, the cyclobutane being a product of the [2 + 2] photocycloaddition (PCA) reaction of the dyad. According to calculations, the dyad forms π‐stacked folded conformers, which, when excited, can form excimers that are precursors of cyclobutane. TD DFT calculations and natural transition orbital (NTO) analysis indicated that the lowest singlet excited S1 state in the dyad is localized on the SBQ photochrome, including the ethylene group that undergoes PCA. Thus, the conditions for concerted electrocyclic reactions are satisfied, and the direct PCA follows the Woodward–Hoffmann rules. In contrast, in cyclobutane, the S1 state is localized on the BQ substituent rather than on the cyclobutane core. Therefore, the reverse ring‐opening (retro‐PCA) reaction cannot follow the Woodward‐Hoffmann rules and inevitably involves a step of excitation energy transfer from BQ to cyclobutane, which means the predissociation mechanism.

AbstractNanoscale superlattice (SL) structures have proven to be effective in enhancing the thermoelectric (TE) properties of thin films. Herein, the main phase of antimony telluride (Sb2Te3) thin film with sub‐nanometer layers of antimony oxide (SbOx) is synthesized via atomic layer deposition (ALD) at a low temperature of 80 °C. The SL structure is tailored by varying the cycle numbers of Sb2Te3 and SbOx. A remarkable power factor of 520.8 µW m−1 K−2 is attained at room temperature when the cycle ratio of SbOx and Sb2Te3 is set at 1:1000 (i.e., SO:ST = 1:1000), corresponding to the highest electrical conductivity of 339.8 S cm−1. The results indicate that at the largest thickness, corresponding to ten ALD cycles, the SbOx layers act as a potential barrier that filters out the low‐energy charge carriers from contributing to the overall electrical conductivity. In addition to enhancing the scattering of the mid‐to‐long‐wavelength at the SbOx/Sb2Te3 interface, the presence of the SbOx sub‐layer induces the confinement effect and strain forces in the Sb2Te3 thin film, thereby effectively enhancing the Seebeck coefficient and reducing the thermal conductivity. These findings provide a new perspective on the design of SL‐structured TE materials and devices.

Published: October 2023

AbstractHigh power conversion efficiencies (PCEs) in perovskite solar cells (PSCs) have always been awe‐inspiring, but perovskite films scalability is an exacting precondition for PSCs commercial deployment, generally unachievable through the antisolvent technique. On the contrary, in the two‐step sequential method, the perovskite's uncontrolled crystallization and unnecessary PbI2 residue impede the device's performance. These two issues motivated to empower the PbI2 substrate with orthorhombic RbPbI3 crystal seeds, which act as grown nuclei and develop orientated perovskites lattice stacks, improving the perovskite films morphologically and reducing the PbI2 content in eventual perovskite films. Thence, achieving a PCE of 24.17% with suppressed voltage losses and an impressive life span of 1140 h in the open air.
Carbon Dots‐Embedded Silica Tubes: An Excitation‐Independent Yellow‐Emitting Turn‐On Probe for Simultaneous Detection and Removal of Inorganic Arsenic with In Vivo Tracking in Living Organisms
Authors: Yadav Sanjay , Choudhary Nishu , Sonpal Vasavdutta , Paital Alok Ranjan 
Published: October 2023

AbstractThe environmental monitoring and remediation of highly toxic inorganic arsenic species in natural water are needed for the benefit of the ecosystem. Current studies on arsenic detection and removal often employ separate materials, which exhibit blue luminescence with fluorescence quenching, making them unsuitable for biological and environmental samples. In this study, carbon dot‐embedded mesoporous silica tubes functionalized with melamine are synthesized to address these limitations and enable specific and turn‐on probing of inorganic arsenic. The newly synthesized material demonstrates excitation‐independent yellow luminescence and can effectively detect both As (III) and As (V) at low detection limits (11 × 10−9 m, 11.2 × 10−9 m), well below the prescribed threshold limits in drinking water. It also exhibits a high adsorption capacity (≈125, 159 mg g−1) with fast kinetics. The material's applicability in environmental samples is validated through the successful quantification of arsenic in real samples with satisfactory recoveries. Moreover, the material shows recyclability for reuse, as demonstrated by its arsenic adsorption and desorption for several cycles under basic conditions. Additionally, the material's capability for monitoring arsenic in a biological sample (Artemia salina) is demonstrated through fluorescence imaging. The encouraging outcomes underscore the material's potential use in monitoring and mitigating arsenic in aqueous systems.
Implementation guide for process safety management

Published: October 2023

AbstractA general guide how to implement process safety management (PSM) is missing in the literature. This article provides general procedure to implement PSM which any industry in underdeveloped, developing and developed countries can adopt to start PSM implementation. PSM implementation can be initiated through the proposed framework consisting of four steps: (1) PSM introduction, (2) Assigning departmental wise PSM duties, (3) Trainings and (4) Audits and improvements. Trainings include process hazard analysis (PHA) using Integrated What‐If/HAZOP analysis, quantitative risk assessments using ALOHA or equivalent software, PSM forms developments and other trainings. In a case study, ammonia release is estimated and quantified using ALOHA. Nine various forms for PSM are required to be developed for industry implementing PSM. Various trainings should be arranged including specific learning outcomes and few examples are discussed in this article. An audit scheme is proposed for any new industry implementing PSM. PSM elements implementation sequence is discussed. New established industries can adopt this procedure to implement PSM following suggested forms and sequences, which can help engineers in understanding PSM implementation. This PSM implementation proposed framework is being implemented in the fertilizer industry and caustic industry.
Profiling wind LiDAR measurements to quantify blockage for onshore wind turbines

Published: October 2023

AbstractFlow modifications induced by wind turbine rotors on the incoming atmospheric boundary layer (ABL), such as blockage and speedups, can be important factors affecting the power performance and annual energy production (AEP) of a wind farm. Further, these rotor‐induced effects on the incoming ABL can vary significantly with the characteristics of the incoming wind, such as wind shear, veer, and turbulence intensity, and turbine operative conditions. To better characterize the complex flow physics underpinning the interaction between turbine rotors and the ABL, a field campaign was performed by deploying profiling wind LiDARs both before and after the construction of an onshore wind turbine array. Considering that the magnitude of these rotor‐induced flow modifications represents a small percentage of the incoming wind speed (
), high accuracy needs to be achieved for the analysis of the experimental data and generation of flow predictions. Further, flow distortions induced by the site topography and effects of the local climatology need to be quantified and differentiated from those induced by wind turbine rotors. To this aim, a suite of statistical and machine learning models, such as k‐means cluster analysis coupled with random forest predictions, are used to quantify and predict flow modifications for different wind and atmospheric conditions. The experimental results show that wind velocity reductions of up to 3% can be observed at an upstream distance of 1.5 rotor diameter from the leading wind turbine rotor, with more significant effects occurring for larger positive wind shear. For more complex wind conditions, such as negative shear and low‐level jet, the rotor induction becomes highly complex entailing either velocity reductions (down to 9%) below hub height and velocity increases (up to 3%) above hub height. The effects of the rotor induction on the incoming wind velocity field seem to be already roughly negligible at an upstream distance of three rotor diameters. The results from this field experiment will inform models to simulate wind‐turbine and wind‐farm operations with improved accuracy for flow predictions in the proximity of the rotor area, which will be instrumental for more accurate quantification of wind farm blockage and relative effects on AEP.
A Simple TLS-Treatment of the Partial EIV-Model as One with Singular Cofactor Matrices I: The Case of a KRONECKER Product for $$Q_A = Q_0\otimes Q_x$$
Authors: Jazaeri Shahram , Schaffrin Burkhard , Snow Kyle 
Published: October 2023

AbstractFollowing the pioneering work in the PhD dissertation by Snow (PhD thesis, Rep. No. 502, Div. of Geodetic Sci, School of Earth Sciences, The Ohio State University, Columbus, OH, USA, 2012), the two articles by Schaffrin et al. (J Geodetic Sci 4(1):28–36, 2014) and by Jazaeri et al. (Z für Vermessungswesen 139(4):229–240, 2014) provided a broad overview of the Total Least-Squares (TLS) adjustment within EIV-Models with singular cofactor matrices. Around the same time, Xu et al. (J Geodesy 86:661–675, 2012) proposed a specific algorithm to find the TLS solution within a partial EIV-Model, which has been improved by various authors since, including Shi et al. (J Geodesy 89(1):13–16, 2015), Wang et al. (Cehui Xuebao/Acta Geodaet et Cartograph Sinica 46(8):978–987, 2017), Zhao (Surv Rev 49(356):346–354, 2017), and Han et al. (Surv Rev 52(371):126–133, 2020), to name a few. On the other hand, it is easy to see that the partial EIV-Model is a special case of the general EIV-Model with singular cofactor matrices and thus does not need a separate class of algorithms unless they are more efficient than the standard algorithms. This, however, does not seem to be guaranteed as will be shown in this contribution for the straight-line adjustment under
$$Q_A = Q_0 \otimes Q_x$$

Published: October 2023

AbstractSuperconducting gravimeters are the most sensitive instruments for monitoring gravitational changes. At the Metsähovi Geodetic Research Station in southern Finland, a superconducting gravimeter has been operating since 1994. It can be used to monitor crustal loading effects affecting the other geodetic measurements made at the station. Gravimeters iGrav-013 and iOSG-022 replaced the old gravimeter SG-T020 at Metsähovi in 2016. The first step was to do a new local tidal gravity modelling for Metsähovi Geodetic Research Station based on the first 5.5 years of iGrav-013 and iOSG-022 superconducting gravimeter data. Here we present the first analysis of the gravity data and the results of tidal analysis of Earth body tides and ocean tidal loading.
Composing the Incomprehensible: A Cinematic Inquiry into Anthroposcenic Proximity
Authors: Vola Joonas 
Published: October 2023

AbstractThis work presents a post-qualitative inquiry into using cinema as a method for studying proximity. The vastness of spatiotemporal dimensions makes the comprehension of the Anthropocene through the lens of closeness a major dilemma. One can try to perceive this epoch in terms of a landscape: a ‘scopic’ scenery seen from a distance or, in contrast, a shape composed from the land by repeated acts and mass of actors. This dominant human influence from the network of actors invested in this geological era in the making is visible in an experimental documentary film,Koyaannisqatsi—The world out of balance(1982). The film utilises timelapse and slow motion to de- and rehumanise the mass and speed of human movement, strategies implemented alongside its musical score, a soundscape of repetitive phrases and shifting layers. These cinematic techniques reveal the ‘anthroposcenic’ in mundane life, locating the hyperobject of the Anthropocene as a perceivable ANThroposcenery.
Suggestions for Future Wanders
Authors: Höckert Emily , Kinnunen Veera , Rantala Outi 
Published: October 2023

AbstractIn this book, we have been messing up and speculating rather than classifying, offering accurate representations or nailing things down. Instead of providing clear answers or claiming to solve the ecological crisis, we have tested different ways of attending to our proximate relations with a curiosity about what might happen or become. In this spirit, the last pages of the book provide suggestions that can help us continue to engage with the mode of wonder in the Anthropocene.
Inquiring with Hospitable Methodologies
Authors: Höckert Emily , Grimwood Bryan S. R. 
Published: October 2023

AbstractIn ‘Inquiring with hospitable methodologies,’ Emily Höckert and Bryan Grimwood engage with postcolonial philosophies of hospitality that approach ethical subjectivity as openness to alterity and ‘the other.’ Following especially in the footsteps of Emmanuel Levinas and Jacques Derrida, the chapter explores what research would be or become, and what research would do, if oriented around the metaphor of hospitality. Through slow thinking with proximate relations and the exchange of letters and postcards, they reflect the different ways hosts and guests—both human and non-human—make space for otherness and negotiate the conditions of hospitality in different kinds of homes. The chapter serves as an invitation to engage in proximate relations with other-oriented ethics of generosity and preparedness to be unprepared.
Becoming Fragile
Authors: Jutila Salla , Höckert Emily , Rantala Outi 
Published: October 2023

AbstractOur chapter springs from discussions about our roles as tourism researchers in the Arctic in the midst of ecological crisis. We see this chapter as an opportunity to become and stay proximate with the idea of fragility as a collective space where we recognise our weaknesses, dependencies, and solidarities—the fragility of life. We approach fragility as a relational notion helping us to gain new understandings of our entanglements with the more-than-human world and as a vital element of carefull research orientations. As our inspiration, we use memory recalling, looking back, and writing about our experiences as tourism researchers at the University of Lapland. The feminist memory-work method highlights the collective construction of memories through sharing, discussing, and theorising about them as a whole. Applying collective memory work on and with fragility offers us a research method that we have started to call a collective fragility work. Our stories underline the importance of recognising our shared fragilities in relational approaches of becoming—of being and living in the damaged world and engaging in research from those premises.
Composition of Weakly Nonlinear Time Invariant Systems
Authors: Beffa Federico 
Published: October 2023

AbstractWhen building large systems, it’s common to construct them by combining smaller subsystems. To gain the ability to investigate such systems, in this section we study the fundamental operation of cascading two systems, that is, of connecting the output of one system to the input of another one. In our treatment we are going to assume that this connection doesn’t change the behavior of the involved systems. This is not always the case. Therefore, before applying what follows, we must carefully ponder this aspect.
Introduction
Authors: Farnsworth Brandon , Grüny Christian 
Published: October 2023

AbstractThe introduction contextualises the question of institutional critique in New Music in three steps: first, it proposes an understanding of institutions that accounts for the fundamental and pervasive character of institutions in human society, their tenaciousness, and their mechanisms of exclusion, drawing on Arnold Gehlen and Sara Ahmed. On this view, denormalisation and/or displacement are a prerequisite for critique. Second, it traces the development of institutional critique in the arts guided by the development of the avant-garde and the questions of critique’s relation to its object, its possible complicity and radicality, and the relation of the different arts. Third, it considers the specific situation of New Music, finding it relatively isolated and fixated on the dispositive of the concert but still identifying numerous artistic and institutional initiatives that point towards a more open understanding of musical practice and call for or practice institutional change.
“We Started Expanding the ‘Us,’ Rather Than Including Someone Else”—Peter Meanwell and Tine Rude Interviewed by Brandon Farnsworth
Authors: Meanwell Peter , Rude Tine , Farnsworth Brandon 
Published: October 2023

AbstractThe festival Borealis—a festival for experimental music in Bergen, Norway, whose artistic director Peter Meanwell and former managing director Tine Rude are being interviewed by Brandon Farnsworth, works with an expanded definition of experimentation in both programming and how it is organised. It focusses on including artists pushing boundaries in a variety of contexts, trying to move beyond being a festival for any one genre. The festival also extends its concept of experimentation to include how it is organised, linking the act of hearing other’s perspectives that experimental music demands of its listeners with fostering a sense of community among marginalised people and groups. This approach has led the festival to implement a number of accessibility and inclusion measures, creating a unique mix of forms of musical experimentation and community-building that materialise many other contributors’ calls for modelling change in both form and content.
“Positioning Myself Between Stools”—Hannes Seidl Interviewed by Christian Grüny
Authors: Seidl Hannes , Grüny Christian 
Published: October 2023

AbstractSeidl discusses with Christian Grüny the limitations of the New Music institution today through the lens of some of his recent work. His approach bears similarities to Reinholdsten’s artist institution, creating ad hoc coalitions of curious collaborators rather than rely on existing customs and defaults, which lead to creating works that mostly re-actualise the structures they are contained within. In doing this, Seidl discusses how much of his artistic practice unfolds in between the institutional norms and expectations of the venues that host his work, revealing further complex puzzles of audience expectations, working methods, and affordances of spaces themselves.
“Framing Europe”—meLê yamomo Interviewed by Theresa Beyer
Authors: yamomo meLê , Beyer Theresa 
Published: October 2023

AbstractYamomo is interviewed by Theresa Beyer about his views on efforts to decolonise New Music, issues of critique that this raises, and how his biographical experience being Dutch and Filipino causes him to reflect on his status in between coloniser and colonised. For Yamomo, decolonialism, as with feminism and queerness before it, has already been eaten up by capitalism and now serves as a way of acquiring more capital. He argues that within contemporary music, the goal must not be to replace one system with another, but rather to focus on understanding the methods through which hierarchies and power positions are perpetuated in order to inform our decision-making as practitioners.
Gender Issues as Criticism Within (New) Music Institutions
Authors: Brüstle Christa 
Published: October 2023

AbstractWhy is the thematisation of gender linked to social criticism and criticism of music institutions as well as criticism of music as institution? Institutions and institutionalised organisations should be regarded as intermediate instances located between society as a whole and the individual. In them, gender relations are created and reproduced, discussed, and transformed. The thematisation of gender and the associated criticism within institutions then means, above all, dealing with gender-specific power relations. Moreover, the spectrum of approaches in art and art studies for thematising gender ranges from criticism of the exclusion of women from history to criticism of the dominance of certain discourses. Therefore, the integration of gender in the field of music implies aspects and measures of institutional gender equality policy as well as fundamental perspectives critical of music discourses, music theory, and musicology, and thus also institutionally critical perspectives.
Darmstadt and Its Discontents
Authors: Iddon Martin 
Published: October 2023

AbstractThough the Darmstadt New Music Courses have often been the site of critique, relatively few of those critiques have brought about concrete change. This might be illustrated in its fullest form in the history of the courses in the 1970s. A sequence of protests appear, on the superficial level, to have been the proximate cause for a gradual transformation of the institution, in its move away from the authority of its earlier senior figures in favour of a more egalitarian model, where different approaches can co-exist. Yet this history belies the ways in which that apparent diversity both repeats the ways in which the territory of new music was historically divided up and that territorial disputes actually prevent criticism of the institution itself, critiques which were being undertaken by a small group of composers who arguably represented a very different possible, unrealised future for new music in the 1980s: Fernando Grillo, Moya Henderson, Christina Kubisch, and Davide Mosconi.
