Published: June 2024

AbstractThe advancement of Zn–Se batteries has been hindered by significant challenges, such as the sluggish kinetics of Se cathodes, limited Se loading, and uncontrollable formation of Zn dendrites. In this study, a bidirectional optimization strategy is devised for both cathode and anode to bolster the performance of Zn–Se batteries. A novel bowl‐in‐ball structured carbon (BIBCs) material is synthesized to serve as a nanoreactor, in which tin‐based materials are grown and derived in situ to construct cathodes and anodes. Within the cathode, the multifunctional host material (SnSe@BIBCs) exhibits large adsorption capacity for selenium, and demonstrates supreme catalytic properties and spatially confined characteristics toward the selenium reduction reaction (SeRR). On the anode, Sn@BIBCs displays triple‐induced properties, including the zincophilic of the internal metallic Sn, the homogenized spatial electric field from the 3D spatial structure, and the curvature effect of the bowl‐shaped carbon. Collectively, these factors induce preferential nucleation of Zn, ensuring its uniform deposition. As a result, the integrated Zn–Se battery system achieves a remarkable specific capacity of up to 603 mAh g−1 and an impressive energy density of 581 W kg−1, highlighting its tremendous potential for practical applications.

AbstractBackgroundIntensive localized therapy is promising for the treatment of rectal cancer. In Japan, chemoradiotherapy (CRT) and neoadjuvant chemotherapy (NAC) are used as preoperative treatments for this disease. Magnetic resonance imaging (MRI) is used to diagnose lateral pelvic node (LPN) metastases, but the changes in LPN findings on MRI following preoperative treatment are unclear. Furthermore, there may be patients in whom LPN dissection can be omitted after CRT/NAC.MethodsPatients who underwent total mesorectal excision with LPN dissection after CRT/NAC at 13 Japanese Society for Cancer of the Colon and Rectum member institutions between 2017 and 2019 were included. Changes in the short diameter of the LPNs after CRT/NAC and the reduction rate were examined.ResultsA total of 101 LPNs were examined in 28 patients who received CRT and 228 in 47 patients who received NAC. Comparison of LPNs before and after CRT/NAC showed that most LPNs shrank after CRT but that the size reduction was variable after NAC. Although some LPNs with a short diameter of <5 mm showed residual metastasis, no metastases were observed in LPNs that were <5 mm in short diameter before and after CRT/NAC and did not shrink after treatment.ConclusionAlthough the short diameter of LPNs was significantly reduced by both CRT and NAC, even LPNs with a short diameter of <5 mm could have residual metastases. However, dissection may be omitted for LPNs <5 mm in short diameter that do not shrink after preoperative CRT or NAC.

Published: June 2024

AbstractSeparation of hydrogen isotopes (D2/H2) attracts wide interest due to its important applications, such as nuclear fusion. Kinetic quantum sieving‐induced separation over tailored nanoporous solids is a promising method; however, the dynamic separation often shows a transient feature, thus a low D2/H2 selectivity even at temperature below 50 K. Herein, we selectively enriched the accessible quantum sieving (AQS) sites in two‐dimensional carbons by chemically growing a pore‐narrowing layer. The spatial density of such AQS sites is 8.5 times higher than that of commercial carbon molecular sieves. The kinetic selectivity of D2/H2 reached 4.6 at 77 K. Column breakthrough experiments revealed that the dynamic D2/H2 separation was enhanced by such a nanopore design. Aspen simulation indicated that D2 was enriched to 93.1% within 11 pressure swing adsorption cycles with a 1% D2/99% H2 mixture as feed.

Published: June 2024

AbstractA phase change microcapsule with n‐octadecane as the phase change core material and melamine formaldehyde resin as the wall material was successfully prepared by in situ polymerization using cellulose nanofibrillar filaments (CNF) as the emulsion stabilizer. The microencapsulation of phase change materials was characterized using scanning electron microscope, Fourier transform infrared spectroscopy x‐ray diffraction, differential scanning calorimetry, and thermogravimetric analysis. The microcapsules had a perfectly spherical morphology with a core‐shell microstructure. The findings revealed that the microcapsules up to the highest efficiency of encapsulation and energy storage of 59.1% and 58.5%, respectively, were achieved when the CNF addition was 0.2 wt%, the core‐to‐wall mass ratio was 3:3.69, and the stirring rate was 1000 r/min. This work uses CNF as an emulsion stabilizer instead of conventional emulsifiers, which reduces the burden on the environment and provides a sustainable method for thermal energy storage and conversion.
Construction and mechanism of efficient flame retardant system for alkali lignin‐enhanced rigid polyurethane foam

Published: June 2024

AbstractThe enhancement of flame resistance and mechanical strength is critical for the utilization of rigid polyurethane foam (RPUF) composites. In this study, the efficient synergistic flame‐retardant system, incorporating dimethyl methylphosphonate (DMMP) and expandable graphite (EG), with the addition of refined alkali lignin (A‐lignin) were aimed to superior fire resistance and mechanical integrity for RPUF. Furthermore, the flame retardancy and charring ability of obtained RPUF were obviously enhanced. Notably, an RPUF mixture containing A‐lignin, DMMP, and EG demonstrated substantial charring at elevated temperatures, improved limiting oxygen index, and met the UL‐94 V‐0 rating. Cone calorimeter test indicated that this formulation produces less heat and smoke than pure RPUF. The flame‐retardant efficacy of obtained RPUF was attributed to the formation of a protective char layer coupled with the free radical neutralization properties of DMMP, collectively enhancing the flame retardancy obtained RPUF. Additionally, this RPUF variant showed significant advancements in both mechanical and thermal performance. This study outlines a successful strategy for developing RPUF composites endowed with enhanced flame retardancy and mechanical strengths.
A novel high reactive initiator system of vinyl‐substituted hydridopolycarbosilane (VHPCS) for lower curing temperature and higher ceramic yields

Published: June 2024

AbstractVinyl‐substituted hydridopolycarbosilane (VHPCS) is widely studied for its low viscosity, abundance of active functional groups, rapid curing, and high ceramic yield. The curing reactions mainly involve the free radical polymerization of vinyl and hydrosilylation reactions, but these reactions typically require high temperatures such as 160–250°C. The curing behavior of VHPCS‐17 with a tert‐butyl peroxybenzoate/Nickel acetylacetonate (TBPB/NIAA) system is investigated using differential scanning calorimetry and in situ Fourier transform infrared. The properties of VHPCS‐17 with different initiator systems and VHPCS with different vinyl contents (under TBPB/NIAA system) are studied using thermogravimetric analysis and x‐ray diffraction. The results demonstrate that the TBPB/NIAA system can facilitate the free radical polymerization of vinyl; moreover, this system decreases the peak temperature of the curing reaction from 251 to 141°C and increases the ceramic yield from 80.49% to 89.88%. The ceramic yield of cured VHPCS increases gradually, reaching 89.88% when the vinyl content is 17%. The grain size of β‐SiC decreases continuously with the increase in vinyl content, while the high‐temperature oxidation‐resistant properties of SiC ceramics obtained from different VHPCSs are not negatively affected.

Published: June 2024

AbstractFlexible strain sensors are attracting attention in areas such as medical monitoring sensing and rehabilitation therapy monitoring due to their powerful ability to sense, process, transmit and display complex information. However, it is an urgent challenge to realize the trade‐off between excellent performances such as high sensitivity, high linearity, wide strain sensing range and high durability. Herein, we prepare stretchable conductive composites with wrinkle composite micro‐crack structure by combining carboxystyrene butadiene rubber (XSBR) layer and carboxymethyl cellulose@Ag nanowire‐CNTs (CMC@AgNWs‐CNTs) conductive layer. Based on interfacial interactions, it can be adapted to different needs by adjusting the thickness of the strain sensing layer. When the thickness of the strain sensing layer is 4 μm, the strain sensor has a wide sensing range (strain capacity up to 300%) and high sensitivity (strain sensing factor of 484). At a thickness of 8 μm, the strain sensing performance exhibits a wide strain range, high linear fit and good cyclic stability. This work provides a new research idea to improve the comprehensive performance of flexible strain sensors and the contradiction between wide sensing range, high sensitivity and high linearity.

AbstractA novel inorganic‐organic‐inorganic ternary bioactive material formulated on antimicrobial peptide‐based polymer has been reported. Supramolecular approach has been employed to incorporate molecularly crowded tyrosine‐based polymer stabilized silver nanoparticles into membrane bound vesicles exploiting polyoxometalate‐triggered surface templating strategy. Utilizing the covalent reversible addition fragmentation chain transfer (RAFT) polymerization and exploiting templated supramolecular architectonics at biopolymer interface, the bioactive ternary polymeric nanohybrids have been designed against Shigellosis leveraging the antibacterial activities of silver nanoparticle, cationic amphiphilic tyrosine polymer and inorganic polyoxometalate. The detail investigation against Shigella flexneri 2a cell line demonstrates that the collaborative mechanism of the ternary hybrid composite enhances the bactericidal activity in comparison to only polyoxometalate and polymer stabilized silver nanoparticle with an altered mechanism of action which is established via detailed biological analysis.
Efficient pricing of path‐dependent interest rate derivatives
Authors: Silva Allan Jonathan da , Baczynski Jack , Vicente José V. M. 
Published: June 2024

AbstractInterest rate derivative pricing is a critical aspect of fixed‐income markets, where efficient methods are essential. This study introduces a novel approach to pricing path‐dependent interest rate derivatives within a broad class of affine jumps. The study's particular setting is the Fourier‐cosine series (COS) method adaptation, which offers an accurate and computationally efficient method for pricing interest rate derivatives. The Fourier‐cosine series approach can be used to compute probability density functions and option pricing with a linear computing complexity and exponential convergence rate. The lack of a quick and precise pricing technique for Asian interest rate options in diverse fixed‐income market scenarios is a research gap that is being addressed. This approach closes this gap by providing quasi‐closed and closed‐form equations for a range of density and characteristic functions, resulting in precise pricing. The results demonstrate the versatility of the COS method in interest rate markets. Similar to what has been previously reported for stock options, the numerical findings demonstrate the extreme precision and computing speed of the pricing and hedging estimations provided here. This method is an innovative approach to interest rate derivative pricing, offering researchers and practitioners a powerful tool for efficiently calculating prices and calibrating options across strikes and maturities.
Introducing reusable food packaging: Customer preferences and design implications for successful market entry
Authors: Noëth Esther , Van Opstal Wim , Du Bois Els 
Published: June 2024

AbstractTo achieve the sustainable development goals and a transition to the circular economy, we need to tackle the problem of single‐use packaging. As reusable packaging options are increasingly available, both from a technical and business perspective, most studies focus on its technical and value chain aspects while largely ignoring customer perspectives. In this paper, we present results from survey data, evaluating customer preferences on reusable food packaging of 40 food product categories, controlling for shopping preferences, personal characteristics and environmental orientation. Our results inform business strategies on market entry for a wide array of food products. Support for reusable food packaging can be mainly found among younger and environmentally conscious customers, which can be identified as first‐mover customer segments. Awareness of the waste problem and the environmental impact of packaging, most specifically on the issue of ‘overpackaging’ food, are shown to be positively related to interest in reusable food packaging. Promising food product markets to introduce reusable packaging are eggs, dry food products and bread‐based products. Reversely, interest in reusable food packaging is low for frozen food products, even among environmentally conscious customers. We formulate recommendations for product managers, designers and policymakers, stressing the importance of social learning by showcasing successful implementations of reusable packaging in classical grocery store outlets.

AbstractThis mixed‐method study of 1,374 Russian‐speaking immigrants living in Finland investigated how different characteristics of their socio‐political integration are reflected in their attitudes towards supporting Ukraine during the war. The results of survey responses showed that trust in Finnish media and engagement with Finnish societal issues predicted stronger ‘pro‐Ukraine’ attitudes (i.e., support for Finland's aid for Ukraine and condemning of Russia's invasion), while experiences of increased hate speech or discrimination of Russian speakers in Finland were related to weaker ‘pro‐Ukraine’ attitudes. Next, person‐centred analysis identified three socio‐political integration clusters. High Integration cluster respondents highly supported Ukraine as compared to Critical and Low Integration clusters. Critical Integration respondents were somewhat more integrated than Low Integration respondents, except they felt that discrimination towards Russian speakers had increased due to the war. Analyses of open‐ended responses confirmed that Critical Integration respondents were most likely concerned with discrimination. Low integration respondents had ambivalent attitudes in that many were opposed to the war but felt that Western countries were also responsible. Our findings highlight the role of socio‐political integration – and especially perceived discrimination – in shaping immigrants' political views during political turmoil. Receiving societies should promote non‐discrimination and inclusiveness to mitigate intergroup conflicts in societies with significant diasporic communities.

AbstractNew 2‐(4‐benzothiazol‐2‐yl‐phenoxy)‐1‐(3,5‐diphenyl‐4,5‐dihydro‐pyrazol‐1‐yl)‐ethanones (9a–o) have been designed and synthesized. All the synthesized compounds were characterized by thin layer chromatography and spectral analysis. The antiepileptic potential of the synthesized compounds has been tested by following standard animal screening models, including maximal electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) models. The neurotoxic and antidepression effects of the synthesized compounds were checked by utilizing rotarod apparatus, and motor impairment test (by actophotometer) respectively. The study concluded that compounds 9c, 9d, 9f, 9i, 9n, and 9o possessed good antiepileptic potential compared to standard drugs like carbamazepine and phenytoin. The results of the rotarod performance test also established them without any neurotoxicity. The motor impairment test revealed that the synthesized compounds are also good antidepressants. In‐silico studies have been performed for calculation of pharmacophore pattern, prediction of pharmacokinetic properties which determine the eligibility of synthesized compounds as orally administered molecules and interactions with the target proteins. The result of in‐silico studies reinforced results obtained by in vivo study of the synthesized compounds and their possible mechanism of antiepileptic action i. e. via inhibiting voltage‐gated sodium channels (VGSCs) and gamma‐aminobutyric acid‐A receptor.

Key Clinical MessageVaginal cuff dehiscence post‐hysterectomy is rare yet significant. Early recognition and prompt surgical intervention are crucial to prevent complications like bowel infarction. Consider second‐look laparotomy in cases of uncertain bowel viability.AbstractVaginal cuff dehiscence (VCD) is a rare but potentially life‐threatening complication following a hysterectomy characterized by the separation of the vaginal vault. This condition, which may result in vaginal evisceration (VE), presents a significant risk of pelvic contents, particularly the small bowel, protruding into the vagina. Early diagnosis and prompt surgical intervention are paramount to prevent severe complications, including bowel infarction, obstruction, and peritonitis. Although VCD and VE are rare, they require urgent surgical management to avoid adverse outcomes. We reported a case of small bowel evisceration in a woman with a history of total abdominal hysterectomy 6 months ago. VCD and VE are very rare but life‐threatening complications of hysterectomy. Discussing the symptoms with patients who have multiple risk factors is crucial to avoid severe sequels following hysterectomy. Based on our experience, performing a second‐look laparotomy is a reliable approach to ensure the viability of the intestinal loop. However, it will likely increase the risk of infection.

Published: June 2024

AbstractA copper‐catalyzed [3+2] annulation reaction of exocyclic enamines/enol ethers with 1,4‐benzoquinone esters has been developed, providing facile access to N,O‐spiroketals and spiroketals under mild conditions with broad substrate scope (26 examples, 71–94 % yields). Gram scale synthesis and chemical transformations demonstrated that this method is potentially useful in the synthesis of natural products and drugs containing a N,O‐ spiroketal moiety. The chiral N,O‐spiroketal could be obtained with 98 % ee after recrystallization, when a chiral SaBOX ligand was employed.

Published: June 2024

AbstractThis paper reports hybrid gels combining a low‐molecular‐weight gelator (LMWG) and a photoinitiated crosslinked polymer gel (PG). The presence of the PG enhanced the stiffness and strength of the gel. The gels were loaded with heparin, and in the hybrid gel, the interpenetrated LMWG and PG networks somewhat restricted its release. In terms of stem cell growth, the hybrid gel significantly improved the performance of the PG because of the presence of the LMWG, which is an excellent substrate for stem cells in its own right. Furthermore, the presence of heparin in the hybrid gels also enhanced stem cell proliferation over longer timescales. Finally, these gels were photopatterned within the well‐plates used for tissue culture, with patterning helping control stem cell proliferation. In summary, these hybrid gels combine the advantageous features of both LMWG and PG: rheological performance is endowed by the PG with stem cell compatibility provided by the LMWG. The hybrid gels also control the release of the bioactive agent heparin and have capacity to be shaped and patterned. Patterned gels such as these, capable of directing stem cell growth, have potential in regenerative medicine.

Published: June 2024

AbstractMussel‐inspired coating is a substrate‐independent surface modification technology. However, its application is limited by time‐consuming, tailoring specific functions require tedious secondary reaction. To overcome those drawbacks, a strategy for the rapid fabrication of diverse coatings by expanding the library of precursors using oxidation coupled with polyamine was proposed. Based on DFT simulations of the reaction pathways, a method was developed to achieve rapid deposition of coatings by coupling oxidation and polyamines, which simultaneously accelerated the oxidation of precursors and polymer chain growth. The feasibility and generalizability of the strategy was validated by the rapid coating of 10 catechol derivatives and polyamines on various substrates. The surface properties of the substrates such as functional group densities, Zeta potential and contact angles can be easily tuned. The tailored surface engineering application of the strategy was demonstrated by the heavy metal adsorbents and superwetting materials prepared through the delicate combination of different building blocks. Our strategy was flexible in terms of diverse surface engineering design which greatly enriched the connotation of mussel‐inspired technique.
