Redox active bio-ionic liquid electrolyte for high energy density Zn-ion capacitor
No full text
Zinc-ion capacitors are gaining a lot of interest due to its safety, recyclability and high theoretical capacity (820 mAh g-1). Aqueous electrolytes are mainly studied in Zn-ion capacitors which limits their electrochemical window and often leads to dendrite formation. In comparison, aprotic ionic liquid electrolytes although increases the electrochemical window, the slow diffusion kinetics of the Zn species often reduces its power density. Here, we show a sustainable and biocompatible redox electrolyte based on bio-ionic liquids (Choline acetate and Choline iodide) for Zn-graphene capacitor which results in a high storage capacity of 350 F g-1 at a current density of 0.5 A g-1. Experimental and DFT-based theoretical studies showed that choline in the electrolyte interacts with graphene and changes its local electronic structure, which results in obtaining a higher capacity. Stability tests performed at 3 A g-1 showed an initial capacity of 160 F g-1 which decreased to 130 F g-1 after 5000 cycles showing a capacity retention of 81.5%. The current study opens up new avenues of using biocompatible hybrid capacitors for various applications. </p
Tackling gambling harm requires a public health approach
No full textHarmful gambling is a global public health issue that is attributable to the rapid expansion of commercial gambling industries which has driven population exposure to high intensity gambling products and commercial practices of the gambling industry.In January 2025, NICE issued guidelines for commissioners and providers of healthcare and social care services, as well as gambling support services, which focus on improving the identification, assessment, and management of gambling harms. This editorial points out that the guidelines focus on the individual, while the gambling industry escapes scrutiny.</p

Toil & Trouble: How We Find Out Who We Are
No full textToil & Trouble challenges the usual exhibition format by inviting guests to change it mid-way through the show!Opening with artworks made and curated by Lucy Renton, Sue Withers and Anna Fairchild.Intended to explore ideas of creativity, control, unpredictability, risk, and trust, the show offers visitors (and participants) thought-provoking ‘before’ and ‘after’ experiences.It also invites fellow artists to think about, and publicly discuss how the uncertainty of the studio can contribute to an exhibition; if critical dialogue between artists can involve actions as well as words; whether exhibiting and curating should be more fluid processes, and how it benefits an artist to swap self-definition for self-discovery.February 28th – Live Disruption by General PracticeHalfway through the show, Lincoln-based artist collective General Practice, have been given carte blanche to rearrange the exhibition. Moving or subtracting works of the original artists, adding works of their own, or introducing other objects, sounds, performances, scents or whatever they consider appropriate as a non-linguistic response to alter the experience of the exhibition for visitors.</p
Impact of credit constraints on adoption of biofortified food crop among farming households in Nigeria
No full text The prevalence of credit constraints has a significant effect on the adoption of biofortified cassava; hence, low productivity on farms. This research, therefore, investigates the effect of credit constraints on the adoption of biofortified cassava (BC) among farming households. A multistage sampling procedure is employed to select 300 cassava farming households for this study. Data is analyzed using descriptive statistics, seemingly unrelated regression, and endogenous switching regression model. The results show that most of the household heads (78%) are not constrained by credit while 22% of respondents are constrained by credit. Out of the 22% that are constrained by credit, 7% are ‘quantity’ constrained (they receive partial credit) while 7.5% are both ‘risk’ (they choose not to submit their applications due to concerns about losing their collateral) and ‘price’ (they do not apply because of high interest rate) constrained. The seemingly unrelated regression model reveals that marital status, household size, years of education and farming experience significantly influenced quantity constraint status; while age, relationship with household head, farming experience and access to information are factors that contribute to the risk constraint status of farming households. The conditional treatment effect (ATT), which assesses the effect of credit constraints on the adoption of BC among farming households, is approximately -11.4 and is statistically significant at 1 %. The study finds that credit constraint has a negative impact on the adoption of BC among farming households in Nigeria after adjusting for both observable and unobserved factors. Therefore, the study recommends that innovative financing mechanisms should be leveraged to help promote the adoption of agricultural technologies such as BC. This will help to improve the nutrition, food security and income of farming households. </p
Embodied Objectivity or Affective History?: Remembering the Early Medieval English and Scandinavians via the Medium of Reenactment and Living History
No full textThis thesis examines how the early medieval English and Scandinavians are remembered among the reenactors and living historians who perform as them, as part of their leisure time activities. It questions how such individuals come to understand and learn about these figures from the early medieval past, as well as how they deem them to be of significance for contemporary society. These research questions were examined via an innovative research model employing focus groups consisting of tasks and discussion topics. Five focus groups were conducted with a total of 21 participants recruited from a diverse set of early medieval reenactment and living history (RLH) societies operating in England.The study found that the majority of participants employed historical modes of memory when remembering the early medieval English and Scandinavians. Over the course of their focus group discussions, participants regularly employed critical and self-reflexive frames of thought, and they engaged with a range of difficult historiographical concepts. Moreover, participants were united in holding empathetic relationships with the early medieval past whereby they felt a deep sense of respect for the shared humanity of the early medieval English and Scandinavians. Utilising these historically empathetic modes of memory led participants to develop detailed and nuanced perceptions of the early medieval pasts they perform. In addition, they led many participants to form constructive bonds between past, present, and future, which help them to make sense of the complex nature of the world around them. In tandem with identifying the historical ways in which the participants remember the early medieval English and Scandinavians, the thesis makes the significant observation that participants achieved their historical modes of memory via a spectrum of both objective and subjective interaction with the early medieval past which, despite their differences, produced historical insights of equal quality and credibility.The findings of the study bear significant implications for the understanding of RLH as a legitimate medium through which to practice history. They present RLH as a multifaceted method of embodied historical enquiry which is highly adept at nurturing empathetic modes of historical memory for its practitioners. They also highlight the potential of RLH as a non?formal learning environment, with several participants being seen to have developed historical modes of memory without any formal direction from history professionals.</p

[Review] The maternal, digital subjectivity, and the aesthetics of interruption by E. L. Putman, London, Bloomsbury, 2022, £66.50 (hardback), £20.29 (paperback), £18.26 (ebook), ISBN: 978-1-5013-9213-9
No full textReview of El Putnam’s The Maternal Digital: Subjectivity and the Aesthetics of Interruption (2022) critically examines the intersections of maternal subjectivity, digital technologies, and artistic performance. Central to Putnam’s argument is the concept of ‘interruption’, a force that disrupts identity, time, and agency, shaping the uncanny realities of contemporary motherhood. Drawing on feminist theory, performance studies, and digital media analysis, Putnam explores how artists such as Fatimah Tuggar, Amanda Coogan, and Mary Kelly navigate the tensions between care, identity, and digital mediation. She critiques the commodification of maternal subjectivity within digital capitalism while also recognising the potential for alternative modes of self-expression and community-building. While the book’s breadth can feel overwhelming, its combination of theoretical rigour, artistic case studies, and personal narrative makes it a vital contribution to feminist digital studies and maternal aesthetics.</p
MAP Indonesia: GENPEACE song video :Yang Berkurang Harus Sampai Hilang"
No full textThis song was created through a collaboration between artists and young participants of the GENPEACE project, from creating the messages (voices) to planning the final performance entitled “Panca Sora” (five voices). This is combined with youth-led identification of children’s issues according to five child rights clusters. This song is one of the artistic outputs that is used in combination with other art forms, i.e., traditional dance, bamboo angklung, wayang (puppet show), and operetta, to collectively reinforce the delivery of children’s voices related to five clusters of the Convention on the Rights of the Child (CRC). The lyrics of the songs represent a particular voice of concern and are embedded with the positive values and philosophy of angklung. The lyrics of the songs reflect on children’s concerns and hopes in relation to their rights.https://doi.org/10.24385/lincoln.28451129</p
