Role of Experimental Damage Mechanics for the Circular Economy Implementation in Cotton Industries
Authors: Hussain Abrar , Abbas Muhammad Mujtaba 
Published: December 2021

Objective:
The objective of the current research was to study the effects of tensile properties of post-consumer cotton fabric on mechanical recycling and shredding. The effect of tensile properties like tensile force, effective tensile force, breaking force, elongation, yield strength on cutting and shredding of cotton textile was measured and demonstrated with literature investigations. In this work, we tried to develop the relationship between tensile testing, subjective assessment, and circular economy.

Methods:
In this manuscript, the quality of post-consumer textile cotton was evaluated using American society for testing of materials (ASTM) D5034-95-08 grab test and the ASTM D5034-95-06 strip test. The fabric surfaces before and after mechanical testing were explored using a scanning electron microscope (SEM). Moreover, the subjective assessment was also performed to observe various physical properties at room temperature.

Results:
The initial scanning electron microscope analysis has proved the damage and distortion in weft and warp directions. The tensile, effective tensile, and breaking force were 86 N, 143 N, and 75 N in the weft direction, and those were 180 N, 227 N, and 170 N in the warp direction. The deformation in terms of the extension was in the range of 10% to 27% in weft and 3% to 8% in warp direction. The scanning electron micrographs after testing confirmed the creation of microfibrils. These microfibrils connect with the fibre core through lignin.

Conclusion:
Higher tensile, breaking force, and effective tensile force increase the purity and quality of the recycled product. The higher values play a vital role throughout operational steps of recycling for enhancement of performance and tactical properties. However, lower mechanical properties produced operation problems such as tangling, buckling, and mixing, which downgraded the quality and performance of polymer products. Technically, these investigations can add value to the concept of the circular economy.

Objective:
The synthesis and structural study of a new acid decavanadate compound with a monovalent inorganic cation. This compound makes a contribution to inorganic decavanadate family.

Methods:
The synthesis of the compound was carried out by evaporation at room temperature. Good quality crystals were chosen for single crystal x-ray diffraction using a polarizing microscope. Hirshfeld surface analysis, in particular dnorm surface and fingerprint plots, is used to decode intermolecular interactions in the structure of the studied decavanadate compound.

Results:
A new acid decavanadate compound, Na2[H4V10O28]·14H2O, was synthesized and characterized by single crystal X-ray diffraction. The decavanadate compound crystallizes in the triclinic system and the cell parameters are: a=11.282(5) Å, b=10.424(3) Å, c=8.502(1) Å, α=112.81(2)°, β=87.25(2)°, γ=111.49(5)°, V=852.4(5) Å3 and Z=2. The formula unit of Na2[H4V10O28]·14H2O compound is formed by an acidic decavanadate group [H4V10O28]2-, a Na2(H2O)102+ dimer and four molecules of water. The decavanadate group is formed by ten distorted VO6 octahedra interconnected by edge sharing. Decavanadate groups [H4V10O28]2-, the Na2(H2O)102+ dimers and the water molecules stack in layers parallel to the (010) plane. The cohesion of the structure is ensured by hydrogen bonds and van der Waals interactions. The study of the Hirshfeld surface shows that O…H/H…O and H…H interactions dominate the structure.

Conclusion:
A novel synthesized decavanadate compound decorated by inorganic cations is reported and studied by X-ray diffraction. The cohesion is assured by: O-H…O hydrogen bonds and van der Waals interactions. The Hirshfeld surface analysis confirms the presence of O…H/H…O and H…H contacts in the structure.
Understanding Thai Urban Pedestrian Culture During Noon Break: How Sidewalk Users Experience the Walking Infrastructure in Bangkok, Thailand
Authors: Janpathompong Shusak , Murakami Akinobu 
Published: December 2021

The noon break or lunch hour in Bangkok’s central business district (CBD) is when pedestrians wander around for various activities and purposes, in addition to having a meal, within a limited time frame. It is the only break from their daily working routines for energy recovery or socializing, which, in turn, increases readiness to continue working in the afternoon. Commercial activities preferred by pedestrians during this break contribute to increased economic activity. Since pedestrian behavior depends on the cultural context, this research aims to understand Thai urban pedestrian culture that benefits the public, both socially and economically, and to investigate pedestrians’ experience of the physical quality of their walking infrastructure, reflecting their preferences.
According to the information gained from observation, a field survey of four hundred thirty observations, and descriptive statistics, the urban pedestrian culture in the CBD of Bangkok is a combination of various activities related to a way of life; 69.4% and 44.9% of observed pedestrians have secondary and tertiary purposes. These multi-purpose trips during lunch hours include having meals, shopping, recovery from work, socializing, and taking care of business or running errands. The routine of lunch outings declined only slightly after the start of the pandemic in early 2020 compared to the pre-pandemic level (81.8% compared to 94.9%). Socializing has strong presence in the culture; 90.5% of group outings occur at least once or twice a week.
On the physical side, the walking infrastructure, mainly comprising sidewalks, is used for circulation and as a place for social and economic settings. Using hierarchical cluster analysis, pedestrians’ concerns about the physical environment were divided into five groups, as follows: Cluster 1, people concerned about thermal comfort, surface conditions, and sidewalk obstructions. Cluster 2, people concerned about thermal comfort and walking distance. Cluster 3, people concerned about level changes and walking distance. Cluster 4, people concerned about surface conditions and sidewalk obstructions. Lastly, cluster 5, people concerned about sidewalk obstructions, traffic safety, and level changes.
In conclusion. significant problems experienced or causing concern to pedestrians include sidewalk obstructions of flow due to insufficient width of the walking space as well as blockages caused by utility infrastructure, or social or economic activities, walking distance, surface conditions of sidewalks, level changes, thermal comfort, and traffic safety, respectively. These experiences and concerns reflect pedestrians’ preference for better quality of walking infrastructure. Therefore, inducing walkability is a promising physical strategy for promoting and sustaining Thai urban pedestrian culture.

Published: December 2021

This article aims to establish the principles for the creation of Buddhist sacred places based on primary sources of the three major sects, namely, Theravāda, Mahāyāna, and Vajrayāna, and studied architecture based on promising secondary sources through case studies. The stated research question is to understand the interaction among Buddhist principles, human activities, and Buddhist architecture in order to develop the criteria for creating Buddhist sacred places in the context of the modern world. The results indicate that criteria should be considered in two aspects. First, a method is required to characterize the context and environment that promotes the practice of virtues such as concentration and wisdom, resulting in mental development. Second, and a method is needed for characterization of the context and activities performed that are appropriate for spiritual cultivation. The proposed criteria offer appropriate methods for developing sacred places in various societies, and contexts comprising any circumstances.

There have been some theoretical studies of high pressure phase transition behavior of BaF	<sub>2</sub>, while in most cases the attention is paid mainly to the optical and electrical properties of BaF	<sub>2</sub> under increasing pressure. To date, there has been still a lack of theoretical explanation for the hysteresis phenomenon of high-pressure phase of BaF	<sub>2</sub> when the pressure is released. In addition, the pressure-dependent behavior of the BaF	<sub>2</sub> band gap is still under controversy, and there are few studies of its high-pressure Raman spectra. Therefore, first principle is used to make a supplementary calculation of the high pressure behavior of BaF	<sub>2</sub>. For a given pressure	<i>P</i> and temperature	<i>T</i>, the thermodynamic stable phase has the lowest Gibbs free energy. The calculations are performed at zero temperature and hence, the Gibbs free energy becomes equal to the enthalpy. Thus, the variation of enthalpy is calculated as a function of pressure to study the high-pressure phase stability of BaF	<sub>2</sub> based on density functional theory as implemented in the Vienna ab initio simulation package (VASP). The results show that the BaF	<sub>2</sub> undergoes two structural phase transitions from	<i>Fm</i>3	<i>m</i>(cubic) to	<i>Pnma</i> (orthorhombic) and then to	<i>P</i>6	<sub>3</sub>/	<i>mmc</i>(hexagonal) with increasing pressure, and their corresponding transition pressures are 3.5 and 18.3 GPa, respectively. By calculating the evolution of lattice constant with pressure, it is found that at about 15 GPa (near the second phase transition pressure), the lattice constants of the	<i>Pnma</i> structure show abnormal behavior (a slight increase in	<i>b</i>	<sub>o</sub> and a slight decrease in	<i>a</i>	<sub>o</sub>). We suggest that this behavior leads the band gap to decrease, indicated by analyzing the calculated results of	<i>Pnma</i> structure of other materials. The	<i>Pnma</i> structure completely transforms into	<i>P</i>6	<sub>3</sub>/	<i>mmc</i> structure at about 20 GPa. By analyzing the phonon dispersion curves of BaF	<sub>2</sub> as a function of pressure, the structural stability information of the material can also be obtained. Then the density functional perturbation theory (DFPT) is used to calculate the phonon dispersion curves of BaF	<sub>2</sub> by VASP code and Phonopy code. The hysteresis phenomenon of the	<i>P</i>6	<sub>3</sub>/	<i>mmc</i> structure, when the pressure is released, is explained by the kinetic stability. The results predict that the	<i>P</i>6	<sub>3</sub>/	<i>mmc</i> structure can be stabilized at least to 80 GPa.

AbstractTrinidad and Tobago are home to three endemic species in the anuran genus Pristimantis, of which two (Pristimantis charlottevillensis and Pristimantis turpinorum) occur in Tobago alone and the third (Pristimantis urichi) is present on both islands. Earlier, the IUCN assessed the conservation status of these species as: P. urichi, Endangered (EN); P. charlottevillensis, Least Concern (LC); P. turpinorum, Vulnerable (VU). However, these assessments were based on very little field‐based evidence. Here, we present survey results which contributed to reassessments as LC, VU and Data Deficient for these three species, respectively. Despite the close proximity of Trinidad to northern Venezuela, the islands do not share any Pristimantis species with the mainland, which holds a rich endemicity of Pristimantis regionally. In this study, we used genetic sequencing from several island populations and compared them to northern Venezuelan endemics to assess genetic divergence for the first time. The time tree analyses found that only the northern Tobago species P. turpinorum is closely related to mainland Pristimantis, with a genetic split dating to the Late Miocene, suggesting a vicariant event of mainland and island species. Pristimantis urichi, although identical between the two islands, remains highly divergent from the mainland species. Similar results were found for P. charlottevillensis. In addition, there was a high level of divergence between P. urichi and P. charlottevillensis. These findings indicate different island colonization events by different lineages. Sequencing other Venezuelan species remains pivotal to unravel the complexity of the colonization episodes in the region, likely influenced by the changing topography and multiple connection and isolation episodes of the islands by eustatic sea‐level changes.

ObjectiveThis study’s objective was to test whether an online video intervention discussing appropriate treatment escalation improves willingness to change treatment in people living with rheumatoid arthritis (RA).MethodsWe conducted a controlled, randomized trial among patients with RA enrolled in ArthritisPower, a United States patient registry. We recruited participants by email and surveyed their assessment of disease activity (patient global), satisfaction with disease control (patient acceptable symptom state), attitudes about RA medications, decisional conflict (decisional conflict scale), and willingness to modify RA treatment (choice predisposition scale, higher scores are better) if or when recommended by their rheumatologist. Intervention groups watched educational videos relevant to a treat‐to‐target (T2T) strategy, whereas control groups viewed vaccination‐related videos as an “attention control.” We compared the between‐group difference in patients’ willingness to modify RA treatment (primary outcome) and difference in decisional conflict about changing RA treatment (secondary outcome) after watching the videos using t tests.ResultsParticipants with self‐reported RA (n = 208) were 90% White and 90% women, with a mean (standard deviation) age of 50 (11) years, and 52% reported familiarity with the RA T2T strategy. We found a significant improvement in between‐group difference in willingness to change RA treatment among intervention versus control participants (0.49 [95% confidence interval 0.09‐0.88], P = 0.02). The effect size (Glass’s delta) for the intervention was 0.48. Decisional conflict about treatment change decreased, but the between‐group difference was not significant.ConclusionThis novel educational patient‐directed intervention discussing appropriate treatment escalation was associated with improved willingness to change RA treatment if or when recommended by a rheumatologist. Further studies should evaluate whether this change in patients’ predisposition translates into actual treatment escalation.

AbstractThe development of environmentally friendly plastics is critical to ensure sustainable development. In contrast to polymer plastics derived from petrochemicals, inorganic minerals, which are the most abundant matter in Earth's crust, are environmentally friendly. However, the brittleness of these minerals limits their applications as plastics. Here, because of the advantages of both biomineralization and inorganic ionic polymerization, the calcium phosphate (CaP, a typical geological and biological mineral) oligomers are used for biomimetic mineralization under the regulation of polyvinyl alcohol and sodium alginate, resulting in flexible CaP nanofibers with periodic structural defects. The assembly of CaP nanofibers produces a hierarchically structured bulk hybrid mineral (HM), which overcomes the intrinsic brittleness of minerals and exhibits plasticity characteristics. HM exhibits better hardness and thermostability than classical polymer plastics due to its dominant mineral composition. Notably, HM is environmentally friendly and degradable in nature, as it can potentially participate in geological cycles, indicating that this material is an optimal plastic substitute. The construction of periodic structural defects within flexible minerals expands the current understanding of materials science.
Engineering Strongly Chiral Plasmonic Lattices with Achiral Unit Cells for Sensing and Photodetection

Published: December 2021

AbstractAlthough the concept of chirality has its origin in chemistry, the field of photonics is actively exploring and utilizing it. A new family of 2D chiral lattices constructed from fully achiral unit cells is introduced here. This type of chiral structure differs fundamentally from previously reported arrays made of chiral unit cells. In this system, circular dichroism (CD) appears due to the electromagnetic interaction between unit cells and the formation of lattice plasmons (LP). Importantly, the CD is strongly enhanced for anisotropic rectangular lattices, whereas the chiral signal in square lattices is found to be relatively weak. The results cover two configurations. The first has an index‐matched environment, and the second includes an asymmetric arrangement of refractive indices. The index‐matched model is preferable and supports ultrasharp LP resonances. Overall, excellent control of the spectral position and broadening of the CD peaks is also demonstrated by tuning the geometry and matrix refractive indices. These results can be useful for engineering polarization filters and chiral biosensors.

Published: December 2021

AbstractImplementing fast‐charging lithium‐ion batteries (LIBs) is severely hindered by the issues of Li plating and poor rate capability for conventional graphite anode. Wadsley–Roth phase TiNb2O7 is regarded as a promising anode candidate to satisfy the requirements of fast‐charging LIBs. However, the unsatisfactory electrochemical kinetics resulting from sluggish ion and electron transfer still limit its wide applications. Herein, an effective strategy is proposed to synchronously improve the ion and electron transfer of TiNb2O7 by incorporation of oxygen vacancy and N‐doped graphene matrix (TNO−x@N‐G), which is designed by combination of solution‐combustion and electrostatic self‐assembly approach. Theoretical calculations demonstrate that Li+ intercalation gives rise to the semi‐metallic characteristics of lithiated phases (LiyTNO−x), leading to the self‐accelerated electron transport. Moreover, in situ X‐ray diffraction and Raman measurements reveal the highly reversible structural evolution of the TNO−x@N‐G during cycling. Consequently, the TNO−x@N‐G delivers a higher reversible capacity of 199.0 mAh g−1 and a higher capacity retention of 86.5% than those of pristine TNO (155.8 mAh g−1, 59.4%) at 10 C after 2000 cycles. Importantly, various electrochemical devices including lithium‐ion full battery and hybrid lithium‐ion capacitor by using the TNO−x@N‐G anode exhibit excellent rate capability and cycling stability, verifying its potential in practical applications.
