Life‐Cycle Assessment of Mineral and Rapeseed Oil in Mobile Hydraulic Systems
Authors: McManus Marcelle C. , Hammond Geoffrey P. , Burrows Clifford R. 
Published: May 2004

SummaryThe use of rapeseed oil in mobile hydraulic systems has become more widespread over recent years. This is because of concern about the environment in which the systems work and the perceived benefit of using such fluids. This article examines the major segments of the life cycle of mineral and rapeseed oil as used in mobile hydraulic systems, with case studies of a forestry harvester and a road sweeper. It shows that the systems running on rapeseed oil are not necessarily better for the environment. Many of the environmental issues examined in the study were affected more negatively by the use of rapeseed oil than mineral oil. The main exception to this was greenhouse gas emissions, which are consistently higher for systems using mineral oil because of the use of fossil resources.This study examines the production of the machinery, the oils, and their use throughout the machines' lives. The poor environmental performance of the rapeseed oil is due mainly to its poor performance in the field. This is because it does not respond as well to high pressure and temperature as mineral oil, causing it to need more frequent replacement during use. This, in turn, influences the definition of the functional unit used in the life‐cycle assessment that was conducted. Also, the rapeseed oil has more corrosive qualities than the mineral oil, and more hydraulic components need replacing during the life of a machine running on rapeseed oil than one running on mineral oil.
A Sustainability Assessment of a Biolubricant

Published: May 2004

SummaryA sustainability matrix has been developed at Shell Global Solutions to show the environmental, social, and economic impacts of a product. The approach aims to be quicker and more cost‐effective than a conventional life‐cycle assessment by focusing on specific areas of concern through the product life cycle and then comparing products by scaling their impacts relative to one another. It provides a way of making qualitative and quantitative assessment that gives a depth to the assessment beyond data analysis. The tool includes subjective judgment, which tends to reflect current thinking in the company. Once the tool has been fully tested on all product types, the indicators that are central to the process will be assessed by external stakeholders. This article describes the development of the sustainability assessment tool and presents an example that compares the sustainability of a biolubricant (an “environ‐mentally acceptable” hydraulic fluid meeting Swedish Standard SS 15 54 34) with that of a conventional mineral‐oil‐based product. The tool provides a quick decision‐making instrument to help Shell decide which products should be marketed for the business to continue on a sustainable path. The tool also provides a more detailed level of information if a more thorough assessment is necessary.
From Apartheid to the New Dispensation: Evangelicals and the Democratization of South Africa1
Authors: Balcomb Anthony 
Published: May 2004

AbstractIn this article, I attempt to distinguish between five responses to the political situation in South Africa made by evangelicals before and after the end of apartheid in April 1994. I characterize the adherents of these positions as the conservatives, the pragmatists, the protagonists of the Third Way, the protagonists of the 'alternative' community and the liberationists. I then attempt to demonstrate their influence in the transformation of South African society towards democracy by undertaking a series of typological case studies of prominent representatives of these positions. In the process, I attempt to unpack some of the theological and political thinking that underlies and explains each position.
Discontinuity and the Discourse of Conversion
Authors: Engelke Matthew 
Published: May 2004

AbstractThis paper focuses on the conversion narrative of a man in the Johane Masowe weChishanu Church, an apostolic church in Zimbabwe. Taking up recent discussions within anthropology on Pentecostal and charismatic churches, the author shows how apostolics talk about conversion as a distinct break with 'African custom'. It is argued that anthropologists of religion need to take such narratives of discontinuity seriously because they allow us to understand better the dynamics of religious change.
'One Day we Will Sing in God's Home': Hymns and Songs Sung in the Anglican Church in North-East Congo (drc)
Authors: Wild-Wood Emma , Wood Peter 
Published: May 2004

Abstract'Songs preach a lot' claim members of the Anglican Church in North-East Congo (DRC). This article analyses what these songs preach and how they convey their message. It examines the theology of the texts as sung in their musical and social context. The songs fall into two broad categories: western hymns translated by missionaries and contemporary songs often composed locally or nationally. They have different but overlapping theologies and functions within worship. Heaven emerges as a central motif in both categories, presenting an eschatological oral theology, which offers comfort, escape and social comment.

Published: May 2004

Abstract
Der Beitrag behandelt den Einsatz Künstlicher Neuronaler Netze (KNN) zur Modellbildung für nichtlineare dynamische, stationäre und instationäre Systeme. Es wird gezeigt, dass Radiale Basisfunktionsnetze (RBF) in Zusammenhang mit dem neu entwickelten schnellen Mehrschritt-Algorithmus die besten Identifikationsergebnisse liefern. Die Struktur des Netzes wird während des Lernprozesses automatisch so lange erweitert, bis für alle Trainingsdaten eine definierte Fehlerschranke unterschritten wird. Am Beispiel einer nichtlinearen Differenzengleichung erster Ordnung mit einem zeitvarianten Faktor werden die Eigenschaften des neuen Identifikationsverfahrens demonstriert und mit anderen bekannten Verfahren verglichen.

AbstractThe visual system is crucial for human perception and learning, and the retina is responsible for pre‐processing visual information. Mimicking the neurobiological functions of the retina provides the basis for neuromorphic vision hardware. Here, an optogenetics‐inspired prototype capable of modifying neuron‐spiking behavior in a retina‐like manner is demonstrated. In addition to basic information processing, neuronal signal transmission in the retina is bio‐faithfully emulated using optical modulation, that is, neuronal firing is inhibited in the dark and activated upon illumination. The proposed single threshold‐switch field‐effect transistor optoelectronic neuron features an ultra‐compact design by integrating a gate‐modulated 2D MoS2 channel with a volatile threshold switch, and optoelectronic performance is achieved through a multi‐physics resistance‐matching mechanism. This study provides a promising pathway toward highly scalable and hierarchically designed spiking electronics, expanding the spectrum of neuromorphic hardware applications in the emerging field of biomimetic vision.

Published: February 2024

AbstractHypoxia and infection are urgent clinical problems in chronic diabetic wounds. Herein, living Chlorella‐loaded poly(ionic liquid)‐based microneedles (PILMN‐Chl) are constructed for microacupuncture oxygen and antibacterial therapy against methicillin‐resistant Staphylococcus aureus (MRSA)‐infected chronic diabetic wounds. The PILMN‐Chl can stably and continuously produce oxygen for more than 30 h due to the photosynthesis of the loaded self‐supported Chlorella. By combining the barrier penetration capabilities of microneedles, the continuous and sufficient oxygen supply of Chlorella, and the sterilization activities of PIL, the PILMN‐Chl can accelerate chronic diabetic wounds in vivo by topical targeted sterilization and hypoxia relief in deep parts of wounds. Thus, the self‐oxygen produced microneedles modality may provide a promising and facile therapeutic strategy for treating chronic, hypoxic, and infected diabetic wounds.

AbstractDelivery of therapeutics to solid tumors with high bioavailability remains a challenge and is likely the main contributor to the ineffectiveness of immunotherapy and chemotherapy. Here, a catheter‐directed ionic liquid embolic (ILE) is bioengineered to achieve durable vascular embolization, uniform tissue ablation, and drug delivery in non‐survival and survival porcine models of embolization, outperforming the clinically used embolic agents. To simulate the clinical scenario, rabbit VX2 orthotopic liver tumors are treated showing successful trans‐arterial delivery of Nivolumab and effective tumor ablation. Furthermore, similar results are also observed in human ex vivo tumor tissue as well as significant susceptibility of highly resistant patient‐derived bacteria is seen to ILE, suggesting that ILE can prevent abscess formation in embolized tissue. ILE represents a new class of liquid embolic agents that can treat tumors, improve the delivery of therapeutics, prevent infectious complications, and potentially increase chemo‐ and immunotherapy response in solid tumors.

AbstractInjectable scaffold delivery is a strategy to enhance the efficacy of cancer vaccine immunotherapy. The choice of scaffold biomaterial is crucial, impacting both vaccine release kinetics and immune stimulation via the host response. Extracellular matrix (ECM) scaffolds prepared from decellularized tissues facilitate a pro‐healing inflammatory response that promotes local cancer immune surveillance. Here, an ECM scaffold‐assisted therapeutic cancer vaccine that maintains an immune microenvironment consistent with tissue reconstruction is engineered. Several immune‐stimulating adjuvants are screened to develop a cancer vaccine formulated with decellularized small intestinal submucosa (SIS) ECM scaffold co‐delivery. It is found that the STING pathway agonist cyclic di‐AMP most effectively induces cytotoxic immunity in an ECM scaffold vaccine, without compromising key interleukin 4 (IL‐4) mediated immune pathways associated with healing. ECM scaffold delivery enhances therapeutic vaccine efficacy, curing 50–75% of established E.G‐7OVA lymphoma tumors in mice, while none are cured with soluble vaccine. SIS‐ECM scaffold‐assisted vaccination prolonged antigen exposure is dependent on CD8+ cytotoxic T cells and generates long‐term antigen‐specific immune memory for at least 10 months post‐vaccination. This study shows that an ECM scaffold is a promising delivery vehicle to enhance cancer vaccine efficacy while being orthogonal to characteristics of pro‐healing immune hallmarks.

AbstractHollow multishelled structures (HoMSs) are attracting great interest in lithium‐ion batteries as the conversion anodes, owing to their superior buffering effect and mechanical stability. Given the synthetic challenges, especially elemental diffusion barrier in the multimetal combinations, this complex structure design has been realized in low‐ and medium‐entropy compounds so far. It means that poor reaction reversibility and low intrinsic conductivity remain largely unresolved. Here, a hollow multishelled (LiFeZnNiCoMn)3O4 high entropy oxide (HEO) is developed through integrating molecule and microstructure engineering. As expected, the HoMS design exhibits significant targeting functionality, yielding satisfactory structure and cycling stability. Meanwhile, the abundant oxygen defects and optimized electronic structure of HEO accelerate the lithiation kinetics, while the retention of the parent lattice matrix enables reversible lithium storage, which is validated by rigorous in situ tests and theoretical simulations. Benefiting from these combined properties, such hollow multishelled HEO anode can deliver a specific capacity of 967 mAh g−1 (89% capacity retention) after 500 cycles at 0.5 A g−1. The synergistic lattice and volume stability showcased in this work holds great promise in guiding the material innovations for the next‐generation energy storage devices.

Published: February 2024

AbstractCopper iodide (CuI) has garnered considerable attention as a promising alternative to p‐type transparent conducting oxides owing to its low cation vacancy formation energy, shallow acceptor level, and readily modifiable conductivity via doping. Although sulfur (S) doping through liquid iodination has exhibited high efficacy in enhancing the conductivity with record high figure of merit (FOM) of 630 00 MΩ−1, solution‐processed S‐doped CuI (CuI:S) for low‐cost large area fabrication has yet to be explored. Here, a highly conducting CuI:S thin‐film for p‐type transparent conducting electrode (TCE) is reported using low temperature solution‐processing with thiourea derivatives. The optimization of thiourea dopant is determined through a comprehensive acid‐base study, considering the effects of steric hindrance. The modification of active groups of thioureas facilitated a varying carrier concentration range of 9 × 1018–2.52 × 1020 cm−3 and conductivities of 4.4–390.7 S cm−1. Consequently, N‐ethylthiourea‐doped CuI:S exhibited a FOM value of 7 600 MΩ−1, which is the highest value among solution‐processed p‐type TCEs to date. Moreover, the formulation of CuI:S solution for highly conductive p‐type TCEs can be extended to CuI:S inks, facilitating high‐throughput solution‐processes such as inkjet printing and spray coating.

AbstractHybrid vapor deposition is one of the most appealing processes for perovskite photovoltaics fabrication, thanks to its versatile nature. By using sequentially different vapor deposition processes tailored to the inorganic and organic perovskite precursors' peculiarities, this type of process gives access to the full potential of vapor deposition. While vapor deposition of metal halides is well understood and mastered, vapor deposition of organohalide species is much more delicate (degradation of vapors, high vapor pressure, setup‐specific constraints). Here, a novel close space sublimation system is reported and in‐depth insights on the conversion into perovskite of a metal halide template are provided. In this evolution of the process, the substrate coated with metal halide template and the organohalide source are loaded together in a dedicated holder, then transferred into a vacuum chamber on a heating element already at temperature setpoint. The system enables a simple, fast, low‐cost, and easy‐to‐reproduce organohalide vapor deposition process. The formation of the perovskite in situ and identification different conversion regimes are studied. Furthermore, the influence of the chemical environment and chamber design on the process are discussed. Compositional tuning and additive engineering in the process are processed and fabricate proof of concept photovoltaic devices reaching high fill factors of 80% and 17% power conversion efficiency for a bandgap of 1.63 eV.

AbstractThe design of aqueous zinc (Zn) chemistry energy storage with high rate‐capability and long serving life is a great challenge due to its inhospitable coordination environment and dismal interfacial chemistry. To bridge this big gap, herein, we build a highly reversible aqueous Zn battery by taking advantages of the biomass‐derived cellulose nanocrystals (CNCs) electrolyte additive with unique physical and chemical characteristics simultaneously. The CNCs additive not only serves as fast ion carriers for enhancing Zn2+ transport kinetics but regulates the coordination environment and interface chemistry to form dynamic and self‐repairing protective interphase, resulting in building ultra‐stable Zn anodes under extreme conditions. As a result, the engineered electrolyte system achieves a superior average coulombic efficiency of 97.27 % under 140 mA cm−2, and steady charge–discharge for 982 h under 50 mA cm−2, 50 mAh cm−2, which proposes a universal pathway to challenge aqueous Zn chemistry in green, sustainable, and large‐scale applications.
Hierarchical self‐assembly of tannic acid/diethylenetriamine on polypropylene for high‐performance separator

Published: February 2024

AbstractIn lithium‐ion batteries (LIBs), separator is used to provide a barrier between the anode and cathode and provide freedom for the transport of lithium‐ions, which serves a key function in inhibiting internal short circuit and improving the battery safety. The limited wettability of commercial polyolefin separators in electrolytes restricts its utilization in extreme environmental conditions. In our work, we choose polypropylene (PP) as the precursor and can address the issue of poor wettability through suitable modification methods. Tannic acid (TA) and diethylenetriamine (DETA) were utilized to coat PP separator via hierarchical self‐assembly approach, and the coating is further stabilized by taking advantage of the specific oxidizing properties of sodium periodate. This method scarcely increases the separator thickness or sacrifices the microporous structure of the original separator. The improved separator not only exhibits outstanding wetting capability and relatively high ion conductivity (1.24 mS cm−1), but also has the highest lithium‐ion migration number of 0.74. This indicates that when the modified separator is applied to LIBs, its electrochemical performance is significantly enhanced. The enhancement in electrochemical performance of LIBs is attributed to the strong absorption and retention ability of the coating on the separator. The reversible capacity of Li/PP‐TD2 separator/LiFePO4 battery is 144.3 mAh g−1 at 2C, which is higher than that of PP separator (117.1 mAh g−1) under the same current density. Even after 200 cycles, the PP‐TD2 separator with two‐layer assembly modification still maintains a higher coulombic efficiency of 97.55% and a discharge capacity of 96.6%. This hierarchical self‐assembly modification of PP provides an effective approach for fabricating high‐performance separator.

So … are family firms more sustainable? On the economic, social and environmental sustainability of family SMEs
Authors: Herrero Inés , López Cristina , Ruiz‐Benítez Rocío 
Published: February 2024

AbstractIn this work, we address the conflicting results that appear in the literature regarding whether family firms are more or less sustainable than nonfamily firms in each of the three dimensions, by focusing on the group that has been largely disregarded: small‐ and medium‐sized family firms (family SMEs). We set a number of hypotheses, which we test in a sample of Spanish manufacturing firms in the food and beverages sector, using structural equation modelling. We conclude that competing arguments coexist both in favour and against these firms being more or less environmentally and economically sustainable, which finally balance themselves out. However, we found out that family firms tend to take greater care of their closer stakeholders, which, together with the importance given to their social relations with external stakeholders, make them champions in terms of social sustainability. Our results show that family firms are able to be more socially sustainable without having to compromise their economic performance in the long term. Finally, as family firms are not an homogeneous group, we analyse whether our results are firm specific, taking into account the role that the number of generations that the family has run the business and the number of generations currently involved in the business exert on firm sustainability, thereby reaching at very interesting conclusions.
