Intergenerational Aesthetics: A Future-Oriented Approach to Aesthetic Theory and Practice
No full textThis article introduces the philosophical subspecialty of intergenerational aesthetics, which centers in the study of aesthetic values and aesthetic choices taking into account the aesthetic appreciation of future generations. Acknowledging a temporal dependency between the present and the future in aesthetics offers a new perspective to explore aesthetic values, perception, and judgments as well as practical aesthetic decisions. This essay discusses the main concerns of intergenerational aesthetics, including its theoretical stakes, its disciplinary and interdisciplinary influences, its normative aspect, and the role of intergenerational thinking in theory and practice. It focuses on aesthetic issues of our surroundings and aesthetic practices that go beyond the classical arts, such as architecture, design, and preservation, as they are directly related to current concerns regarding sustainability and the environment. It presents a specific case to illustrate the pressing importance of introducing intergenerational considerations to our current aesthetic practices. It ends by proposing a series of potential avenues of research for further investigations in the field.Peer reviewe
In-situ construction of multifunctional femtosecond laser-induced graphene on arbitrary substrates
No full textThe construction of laser-induced graphene (LIG) on various substrates is important for expanding new applications. However, current LIG transfer technologies are hampered by limited substrates, complicated process, induced graphene defects, and single function. Herein, a facile laser processing method is proposed for in-situ construction of multifunctional femtosecond laser-induced graphene (FsLIG) on arbitrary substrates utilizing femtosecond laser acting on polyimide tape. Unlike previous LIG transfer research, the proposed method is applicable to any substrates without introducing additional graphene defects, while also exhibiting multifunctionality. Raman spectra results confirm successful fabrication of FsLIG on various substrates involving paper, aluminum, ceramic, and silicon. Taking paper for example, the FsLIG demonstrates multifunctional characteristics including high water contact angle (∼153.4°), large absorptance (∼98.8%), low sheet resistance (∼82.0 Ω sq−1), and reliable temperature sensing (∼−0.089% °C−1) properties. Our study provides a reliable pathway for fabricating multifunctional FsLIG on arbitrary substrates.Peer reviewe

Driven polymer translocation through a nanopore from a confining channel
No full textPublisher Copyright: © 2025 Author(s).We consider the dynamics of pore-driven polymer translocation through a nanopore to a two-dimensional semi-infinite space when the chain is initially confined and equilibrated in a narrow channel. To this end, we use Langevin dynamics (LD) simulations and iso-flux tension propagation (IFTP) theory to characterize local and global dynamics of the translocating chain. The dynamics of the process can be described by the IFTP theory in very good agreement with the LD simulations for all values of confinement in the channel. The theory reveals that for channels with a size comparable to or less than the end-to-end distance of the unconfined chain, in which the blob theory works, the scaling form of the translocation time depends on both the chain contour length and the channel width. Conversely, for a very narrow channel, the translocation time only depends on the chain contour length and is similar to that of a rod due to the absence of spatial chain fluctuations.Peer reviewe

Exploring effective thermal energy exchange potential of delta-nabla-trapezoidal channels in heat exchangers
No full textPublisher Copyright: © 2024 Elsevier LtdThe performance and thermal efficiency of a heat exchanger are critical in various industrial applications, necessitating the continuous improvement of the thermal management system. In the present study, a novel heat exchanger which comprises of delta-nabla-trapezoidal (DNT) configurations of flow channels, is investigated and compared with commercially available concentric tube heat exchangers (CTHEs), to address the limitations of conventional design in terms of thermal efficiency and pressure drop. The current study is the first of its kind to explore the thermal energy exchange potential of the delta-nabla-trapezoidal heat exchangers (DNTHEs) with numerical simulations and experimentally validated them using an in-house designed experimental setup. The proposed heat exchanger comprises of triangular and trapezoidal cross-section channels that are arranged such that the hot fluid flows through the delta and nabla channels while cold fluid flows through the trapezoidal channels. The energy exchange between the two fluid streams is experimentally measured, and Nusselt number correlations are developed for various inlet mass flow rates. The numerical simulations are then used to predict local fluid and heat flow patterns with velocity and temperature profiles. Experimental results indicate a reasonable energy balance, revealing a maximum loss of 15% across all sets of experiments. Furthermore, the cold-side temperature increased to its maximum of 22 K, while the hot-side temperature decreased by 25 K across all tested conditions. The simulation results demonstrated an enhanced energy balance, characterized by a maximum loss of 10%. The thermal efficiency of the proposed DNTHE was experimentally assessed and compared to that of a CTHE in parallel and counter flow configurations. Under similar operating conditions, the maximum heat flux in DNTHE and CTHE was 18.35 and 14.26 kW/m2, respectively. Furthermore, the largest difference in temperature drops and gains between DNTHE and CTHE are 15 and 9 K, respectively. These findings confirmed the efficient thermal energy exchange potential of DNTHE in comparison to CTHE, establishing a new industrial standard for heat exchangers.Peer reviewe
Researching with and through Costume: Proposition for a Research Framework
No full textWhat are the research possibilities that costume offers beyond its crucial role in co-creating characters and performances? This contribution focuses on performance costume as a means for new research and on processes of costume creation that enable new research methodologies to be established. When looking at costume not only as an artistic outcome integral to performance making – its most familiar and longstanding dimension – but also as a field for open-ended experimentation, costume’s research potential emerges from its practice. The chapter examines contemporary methods and approaches for costume research through the costume itself as methodological research ‘tool’.Peer reviewe
Stretch to scatter : mechanically tunable haze in silica nanofibers - polymer composite films
No full text| openaire: EC/H2020/742829/EU//DRIVEN | openaire: EC/HE/101142496/EU//Dyna-MatHigh-haze materials have been widely used in optical and photonic applications, yet most exhibit fixed internal structures with static haze levels, limiting their adaptability across different usage scenarios. Here, we report a facile strategy to fabricate strain-dependent tunable high-haze films by blending silica nanofibers (NFs) into a polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene (SEBS) matrix. The composite SEBS/NF films exhibit increasing light scattering and haze with the NF content, reaching up to 94 %. Upon mechanical stretching, the absence of chemical bonding between the rigid NFs and flexible SEBS allows interfacial sliding, generating nanoscale cavities. These cavities significantly amplify the internal refractive index mismatch, leading to a reversible and strain-dependent enhancement of haze. In addition, the inherent hydrophobicity of SEBS promises environmental stability and anti-fouling properties, enabling robust performance in underwater conditions. Together, these features position the SEBS/NF films as promising candidates for multi-functional optical systems, including underwater light diffusers and adaptive light management devices.Peer reviewe
Experimental investigation on freezing point depressions and thermodynamic modelling of NiSO4-H2O and NiSO4-H2SO4-H2O systems using Pitzer equations from eutectic point up to 523.15 K
No full textPublisher Copyright: © 2025 The Author(s)One previous study developed a consistent Pitzer model by employing nine terms of virial coefficients for NiSO4-H2O system and four additional terms for the NiSO4-H2SO4-H2O system. The present work incorporates five additional experimental datasets that had not been previously utilized and re-evaluates the entire datasets to refine the NiSO4-H2O and NiSO4-H2SO4-H2O models. The NiSO4-H2O system was modelled from the eutectic point up to 523.15 K, utilizing eight terms of Pitzer parameters. Due to the scarcity of freezing point data beyond 0.2 mol·kg−1 of NiSO4, fifty-six experimental data points were generated in the current study, extending from 0.0015 to 1.56 mol·kg−1. The root-mean-square deviations for the models were determined to be 0.09 for solubility, 0.0001 for water activity on freezing curve, 0.0009 for isopiestic water activity, 0.026 for mean activity coefficients of NiSO4, and 115 J·mol−1 for the apparent relative molal enthalpy of solution. The NiSO4-H2O model was then utilized to develop two types of NiSO4-H2SO4-H2O models based on the Pitzer parameter combination: β0-β1-Cϕ and β0-β1-ψ. While the first type is generally consistent up to 523 K, the latter is exceptionally well for low temperature predictions. A comprehensive analysis and screening of each dataset is provided.Peer reviewe
