Tracking the chemical life histories of spruce resin-beeswax mixtures through degradation experiments using reflectance-mode FTIR

open access: yesFrontiers in Materials
Within residue analysis, experimental degradation studies provide a critical bridge between pristine, modern-day reference materials and the altered residues encountered archaeologically. Here we report on outcomes of a 3-year burial experiment involving

Enhancing the fastness characteristics of weld‐dyed cotton and recycled nylon 6,6 fabrics via sodium alginate and titanium dioxide

open access: yesColoration Technology, EarlyView.
Abstract This study investigates a sustainable dyeing and finishing strategy for recycled nylon 6,6 and organic cotton fabrics dyed with weld. Following meta‐mordant dyeing using alum under Natural Organic Dye Standard (NODS)‐compliant conditions, the fabrics were subjected to functional finishing with titanium dioxide as a multifunctional ...

Investigation into the dyeing of pre‐mordanted & cationised woven cotton fabric with cochineal

open access: yesColoration Technology, EarlyView.
Abstract Dyeing cotton with natural dyes typically requires the pre‐application of a mordant, which enables better dye exhaustion from solution and ‘fixes’ the colorant in the fibre. The most common application system for cellulosic fibres is a combination of plant‐derived tannins and aluminium salts, such as aluminium sulphate.

Success and failure in England's patent system: New evidence from patent applications, 1783–1834

open access: yesThe Economic History Review, EarlyView.
Abstract Our understanding of the relationship between the English patent system and technical change during the industrial revolution is based entirely on the study of successful patents. We address this feature by providing the first study of unsuccessful patent applications in England during the first industrial revolution.

‘Elbow grease and yellow soap’: Housework time in working‐class households in late‐nineteenth and early twentieth‐century Britain

open access: yesThe Economic History Review, EarlyView.
Abstract Housework is central to feminist calls for recognition of women's work, economic histories explaining the sexual division of labour, and claims regarding the progressive role of scientific knowledge. Yet little is known about the time it actually took. We address this lacuna.

Examining the Role of Artificial Intelligence in Assessment: A Comparative Study of ChatGPT and Educator‐Generated Multiple‐Choice Questions in a Dental Exam

open access: yesEuropean Journal of Dental Education, EarlyView.
ABSTRACT Aim To compare the item difficulty and discriminative index of multiple‐choice questions (MCQs) generated by ChatGPT with those created by dental educators, based on the performance of dental students in a real exam setting. Materials and Methods A total of 40 MCQs—20 generated by ChatGPT 4.0 and 20 by dental educators—were developed based on ...

Mergers and Acquisitions as Navigators of Climate Policy Shocks: Evidence from the NOx Budget Trading Program

open access: yesFinancial Management, EarlyView.
ABSTRACT We examine how mergers and acquisitions (M&As) enable firms to adapt to climate policy shocks. Exploiting the adoption of the Nitrogen Oxides (NOx) Budget Trading Program (NBP) across US states as an exogenous shock, we find that firms with NOx‐emitting plants subject to the NBP are more likely to engage in M&As, particularly through vertical ...

Improving The Tribological Characteristics of In-House Made Acid-Activated Iraqi Bentonite Lubricating Greases Using Graphite and Polytetrafluoroethylene Nanoplatelets as Additives

open access: yesDiyala Journal of Engineering Sciences
Traditional soap-based greases such as lithium and calcium are no longer able to meet the requirements of high-performance lubrication due to their high cost and environmentally harmful nature, thus there is a need for new solid, non-organic and non ...

Comparative evaluation of the attractiveness of new polyethylene screens versus West African tiny target for the control of tsetse flies

open access: yesMedical and Veterinary Entomology, EarlyView.
The material has no significant difference in captures (non‐shiny cotton‐polyester screens vs. the shiny polyethylene screens), but the vertical screen attracted significantly more G. tachinoides for each type of material. Full white horizontal screen was significantly lower than the reference WATT.
