Health in a post-COVID-19 world

In the previous article in this issue (S Afr J Sci. 2022;118(11/12), Art. #13165), the emergence and spread of COVID-19 pari passu with climate change and planetary degradation were interpreted as late manifestations in the trend towards gradual decline into disorder (entropy) in an unstable and ecologically threatened planet. In this article, as we contemplate a post- COVID world, the question is whether new insights could generate courageous, prescient leadership towards new paradigms of health, politics, economics, society, and our relationship with nature. A gloomy prognosis is postulated because of the power of many impediments to such changes, both in an increasingly polarised world and in South Africa as a microcosm. Despite many squandered opportunities and a decline in local and global cooperation between all who have a stake in the future, some hope is retained for innovative shifts towards sustainable futures. Significance: Precarious local and global instabilities are vivid reminders of our interconnectedness with each other and with nature. Insights into local and global threats and opportunities, call for paradigm shifts in thinking about and taking action towards a potentially sustainable future in a country that has its own unique history and problems but is also a microcosm of the world. The impediments to making appropriately constructive paradigm shifts in many countries with their tendencies to authoritarianism that threaten peace and democracy, are even more complex in South Africa, where opportunities for dialogue and cooperation are diminishing. Retaining some hope, with vision and courage for innovative shifts towards a sustainable economic/ecological paradigm locally and globally, is arguably essential

The Divine Pedagogy: Theological Explorations of Intelligent Extraterrestrial Life

Abstract Speculation regarding the plurality of worlds and its closely related subject of the existence of intelligent extraterrestrials has remained an important question for Christian theology from antiquity until the modern age. Advancements in space science of the twentieth and twenty-first centuries have revealed a vast universe containing trillions of galaxies, as well as new discoveries of exoplanets, which has provided an unprecedented greater context and perspective in consideration of the place of humanity, possible intelligent extraterrestrials, and the role of divinity in relation to creatures. This has led to increased importance to the question regarding the relation of extraterrestrials to the Christian doctrines of the Incarnation and Redemption, which for centuries has evaded theological resolution. Historically, a handful of theologians have given limited attention to the question of the redemption of possible extraterrestrials, and since early Christianity have proposed several possible solutions, which are categorized according to four types: an exclusive view, asserting a single divine incarnation and salvation provided solely for humans on Earth, without access to potential extraterrestrials; an inclusive view, which includes extraterrestrials within the redemptive sacrifice of Christ on Earth; a multiple view, which posits multiple incarnations of the Logos in extraterrestrial civilizations for their redemption; and a varied view, which argues for the total freedom of divine plans in the salvation of intelligent extraterrestrials. This thesis will argue for the varied view in consideration of intelligent extraterrestrials, which allows for the ‘omni-properties’ of divinity in the creation and redemption of intelligent creatures according to divine prerogative. Examination of the history of developments in scientific and theological thought on extraterrestrials, from antiquity to the twenty-first century will demonstrate a consistent pattern of theological formulations of extraterrestrials and their relation to Christian Christology and Soteriology. In the discussion of this subject, an extraterrestrial ‘anthropology’, psychology, morphological possibilities, sociological compositions, extraterrestrial religions, implications of contact, and a ‘divine pedagogy’ of potential modalities of extra-mundus supernatural presence and action will be considered

New Designs for Wearable Technologies: Stretchable e-Textiles and e-Skin

This dissertation comprises research efforts in addressing the challenges of integration of different materials with mechanical mismatches in stretchable e-textiles and e-skin, with a major focus on the design and fabrication of stretchable e-textiles. Chapter 2 describes the solution-based metallization of a knitted textile that conformally coats individual fibers with gold, leaving the void structure intact. The resulting gold-coated textile is highly conductive, with a sheet resistance of 1.07 ohm/sq in the course direction. The resistance decreases by 80% when the fabric is stretched to 15% strain and remains at this value to 160% strain. This outstanding combination of stretchability and conductivity is accompanied by durability to wearing, sweating, and washing. Low-cost screen printing of a wax resist is demonstrated to produce patterned gold textiles suitable for electrically connecting discrete devices in clothing. The fabrication of electroluminescent fabric by depositing layers of device materials onto the gold-coated textile is furthermore demonstrated, intimately merging device functionality with textiles for imperceptible wearable devices. Chapter 3 presents a new textile-centric design paradigm in which we use the textile structure as an integral part of wearable device design. Coating the open framework structure of an ultrasheer knitted textile with a conformal gold film using solution-based metallization forms gold-coated ultrasheer electrodes that are highly conductive (3.6 ± 0.9 ohm/sq) and retain conductivity to 200% strain with R/R0 \u3c 2. The ultrasheer electrodes produce wearable, highly stretchable light-emitting e-textiles that function to 200% strain. Stencil printing a wax resist provides patterned electrodes for patterned light emission; furthermore, incorporating soft-contact lamination produces light-emitting textiles that exhibit, for the first time, readily changeable patterns of illumination. Chapter 4 demonstrates the strategic use of a warp-knitted velour fabric in an “island-bridge” architectural strain-engineering design to prepare stretchable textile-based lithium ion battery (LIB) electrodes. The velour fabric consists of a warp-knitted framework and a cut pile. We integrate the LIB electrode into this fabric by solution-based metallization to create the warp-knitted framework current collector “bridges”, followed by selectively deposition of the brittle electroactive material CuS on the cut pile “islands”. As the textile electrode is stretched, the warp-knitted framework current collector elongates, while the electroactive cut pile fibers simply ride along at their anchor points on the framework, protecting the brittle CuS coating from strain and subsequent damage. The textile-based stretchable LIB electrode exhibited excellent electrical and electrochemical performance with a current collector sheet resistance of 0.85 ± 0.06 ohm/sq and a specific capacity of 400 mAh/g at 0.5 C for 300 charging-discharging cycles, as well as outstanding rate capability. The electrical performance and charge-discharge cycling stability of the electrode persisted even after 1000 repetitive stretching-releasing cycles, demonstrating the protective functionality of the textile-based island-bridge architectural strain-engineering design. Chapter 5 demonstrates the engineering of metal cracking patterns using the topography from acid-oxidized PDMS. Oxidizing the surface of PDMS with aqueous acid mixture created hierarchical topographies. Coating the surface of acid-oxidized PDMS with copper using electroless deposition produced stretchable conductors with a sheet resistance of ~1.2 ohm/sq. The cracking patterns of copper films with strain were tuned by simply adjusting the composition of acid mixture to change the topography of PDMS, which affects the resistance change of copper films with strain. The Cu films with an optimal cracking pattern on acid-treated PDMS remain conductive to 85% strain with R/R0 less than 20
