AbstractWe present a second near‐infrared (NIR‐II) self‐checking molecule, LET‐1052, for acidic tumor microenvironment (TME) turn‐on photothermal therapy (PTT), followed by viscosity based therapeutic efficacy evaluation by itself in two independent channels, denoted as “self‐checking” strategy. In acidic TME, LET‐1052 was protonated and turned on NIR‐II absorption for PTT under 1064 nm laser irradiation. Subsequently, PTT‐induced cellular death increases intracellular viscosity, which inhibited the intramolecular rotation of LET‐1052, resulting in the enhancement of NIR‐I fluorescence for real‐time evaluation of PTT efficacy. After PTT of tumor‐bearing mice for different periods of NIR‐II laser irradiation, NIR‐I fluorescence in the tumor region showed positive correlation with tumor growth inhibition rate, demonstrating reliable and prompt prediction of PTT efficacy. The strategy may be expanded for instant evaluation of other therapeutic modalities for personalized medicine.

AbstractThe synthesis of long n‐peri‐acenes (n‐PAs) is challenging as a result of their inherent open‐shell radical character, which arises from the presence of parallel zigzag edges beyond a certain n value. They are considered as π‐electron model systems to study magnetism in graphene nanostructures; being potential candidates in the fabrication of optoelectronic and spintronic devices. Here, we report the on‐surface formation of the largest pristine member of the n‐PA family, i.e. peri‐heptacene (n=7, 7‐PA), obtained on an Au(111) substrate under ultra‐high vacuum conditions. Our high‐resolution scanning tunneling microscopy investigations, complemented by theoretical simulations, provide insight into the chemical structure of this previously elusive compound. In addition, scanning tunneling spectroscopy reveals the antiferromagnetic open‐shell singlet ground state of 7‐PA, exhibiting singlet–triplet spin‐flip inelastic excitations with an effective exchange coupling (Jeff) of 49 meV.

Published: February 2022

AbstractBiobased flame‐retardant polylactic acid composites were prepared using ammonium polyphosphate (AP), lignin, and a raw montmorillonite (ANa) as the intumescent formulation. The concentration of AP and of ANa was varied in order to study its influence on the flammability properties of the composites. The samples were submitted to cone calorimeter test, thermogravimetric analysis coupled to Fourier‐transform infrared spectroscopy (TGA‐FTIR), limiting oxygen index (LOI), and UL‐94 vertical burn. The cone calorimeter residues were analysed through scanning electronic microscopy, X‐ray diffraction, and FTIR. The results show that the combined addition of the intumescent formulation and the ANa leads to an improvement in the fire behavior of the composites, compared with that of the neat polymer. The best fire‐retardant performance was achieved by using the highest AP concentration (17%) and the lowest ANa concentration (1.2%), reaching a LOI value of 39%.

AbstractThe present work aims to investigate the potentiality of reinforcing coconut tree peduncle fiber an agro‐waste with unsaturated polyester resin, optimizing its mechanical properties and promote as an alternative reinforcement to harmful synthetic fiber polymer composites. It was found that polymer composites with 40 wt% fiber content exhibited maximum mechanical properties and started to decline on further addition of fibers due to lack of sufficient resin to wet the fibers leading to fiber pull‐out and debonding under applied loads. This was also evidenced from the observed micrograph of specimen undergone tensile failure. In addition, the chemical bonding between the fiber and matrix was confirmed through Fourier transform infrared analysis. Also, the thermal stability was ascertained by the degradation temperature obtained through thermo‐gravimetric analysis. Moreover, the water absorption study in fresh and seawater exposed the pseudo‐Fickian behavior and aquatic properties of the developed composite, which was further confirmed by the crystalline size obtained through X‐ray diffraction analysis. The above holistic analysis of the fabricated composite ensures its sustainable use in automotive and marine industries.

Abstract

Incidental catch of marine species can create ecological and economic issues, particularly for endangered species. The smalltooth sawfish (Pristis pectinata) is endemic to the Atlantic Ocean and listed as Endangered in the US Endangered Species Act. One of its major threats is bycatch mortality in commercial fisheries.
Despite the protection afforded by the US Endangered Species Act, smalltooth sawfish are still captured as bycatch in commercial fisheries. Acoustic and satellite tag data collected on 59 sawfish between 2011 and 2019 were analysed to assess commercial fishery bycatch risk for large juveniles and adults off Florida. This study focused on shrimp trawl, south‐east coastal gillnet, and shark bottom longline fisheries, as these were identified in the recovery plan as having the greatest potential threats to recovery.
Bycatch risk associated with the shrimp trawl fishery was significantly higher than the other fisheries, indicating that this fishery currently poses the greatest threat to recovery.
Bycatch risk was concentrated in all seasons in the Gulf of Mexico adjacent to the lower Florida Keys for the shrimp trawl fishery, off Cape Canaveral in the south‐east coastal gillnet fishery, and in the Atlantic Ocean adjacent to the Florida Keys in the shark bottom longline fishery.
Tagging location and sex were predictors of bycatch risk. Individuals tagged in Charlotte Harbor had the highest shrimp trawl bycatch risk. Females tagged in south Florida tended to reside in the deepest water, which is where shrimp trawl effort is highest. Therefore, females may be at more risk in these deeper waters.
Results from this study indicate a year‐round closure of waters off south‐west Florida to the shrimp trawl fishery between Charlotte Harbor and the western Florida Keys would reduce sawfish bycatch, and thus mortality, which is in line with recovery plan goals.
New tools suggest a middle Jurassic origin for mammalian endothermy
Authors: Newham Elis , Gill Pamela G. , Corfe Ian J. 
Published: February 2022

AbstractWe suggest that mammalian endothermy was established amongst Middle Jurassic crown mammals, through reviewing state‐of‐the‐art fossil and living mammal studies. This is considerably later than the prevailing paradigm, and has important ramifications for the causes, pattern, and pace of physiological evolution amongst synapsids. Most hypotheses argue that selection for either enhanced aerobic activity, or thermoregulation was the primary driver for synapsid physiological evolution, based on a range of fossil characters that have been linked to endothermy. We argue that, rather than either alternative being the primary selective force for the entirety of endothermic evolution, these characters evolved quite independently through time, and across the mammal family tree, principally as a response to shifting environmental pressures and ecological opportunities. Our interpretations can be tested using closely linked proxies for both factors, derived from study of fossils of a range of Jurassic and Cretaceous mammaliaforms and early mammals.
Extraction, isolation, purification, derivatization, bioactivity, structure–activity relationship, and application of polysaccharides from White jellyfungus
Authors: Lin Bobo , Huang Gangliang 
Published: February 2022

AbstractWhite jellyfungus is one of the most popular nutritional supplements. The polysaccharide (WJP) is an important active component of White jellyfungus, it not only has a variety of biological activities but also is nontoxic to humans. So, many scholars have carried out different research on WJP. However, the lack of a detailed summary of WJP limits the scale of industrial development of WJP. Herein, the research progress of WJP in extraction, isolation, structure, derivatization, and structure–activity relationship was reviewed. Different extraction methods were compared, the activity and application of WJP were summarized, and the structure–activity relationship of WJP was emphasized to provide effective theoretical support for improving the utilization of WJP and promoting the application of related industries.
Recent progress in computational discovery of Heusler alloys
Authors: Jin Taewon , Jung Yousung 
Published: February 2022

AbstractHeusler alloy is an intermetallic alloy with a wide range of compositional space. Due to this compositional tunability, novel Heusler alloys have been studied for a variety of applications including permanent magnets, thermoelectric, and catalysis. Recently, computational approaches have been actively used to aid the fast discovery of novel Heusler alloys by identifying stable compositions with desired properties. In this mini‐review, we briefly overview several computational approaches used for Heusler alloys, namely, density functional theory (DFT) calculations, high‐throughput virtual screening (HTVS), and machine learning (ML) to further accelerate these screening processes. Future directions for the computational screening of Heusler alloy in other application fields are discussed.
Global modern slavery and sustainable development goals: Does institutional environment quality matter?
Authors: Moussa Tantawy , Allam Amir , Elmarzouky Mahmoud 
Published: February 2022

AbstractModern slavery is a persistent human tragedy and a growing organisational risk. The United Nations' sustainable development goals highlight the significance of governments in shaping firms' sustainability agenda and combating modern slavery. However, little is known about the effects of the institutional environment on modern slavery risk. This study, therefore, investigates the crucial policy question of whether the quality of the institutional environment has any effect on modern slavery and whether sustainable human development reinforces this relationship. Using data from 167 countries, we find that institutional environment quality is negatively associated with the prevalence of and vulnerability to modern slavery and positively associated with its modern slavery risk mitigation. Our results suggest that democratically elected governments operating in politically stable societies with higher quality of voice and accountability, higher levels of control of corruption, and stricter rule of law are more accountable and responsive to modern slavery risks. We also find that sustainable human development (HDI) has a moderating effect on the relationship between institutional environment quality and modern slavery, and this effect is mainly noticeable in low HDI countries. These results imply that governance reforms alone might not yield the desired effects for all countries and, hence, have significant implications for policymakers, companies, and societal stakeholders.
From materialism to hedonistic shopping values and compulsive buying: A mediation model examining gender differences
Authors: Tarka Piotr , Harnish Richard J. , Babaev Jasurbek 
Published: February 2022

AbstractAlthough prior research has extensively focused on explaining the direct mechanisms of the materialism‐compulsive buying relationship or stressed selected indirect variables such as consumers' social status, money attitudes, well‐being, emotions and identity, little research has examined how materialism impacts compulsive buying via hedonistic shopping values in a former communist economy that has transitioned to a democratic economy. Thus, we examined the materialism‐compulsive buying relationship in term of a mediational model that includes the theoretical construct of hedonistic shopping values. Additionally, the model's postulated relationships are explained from the perspective of gender differences, through the agency of moderated effects. Data for study were obtained from the Polish Household Survey resulting in a nationally representative sample (N = 1245). Results imply that materialism is related to compulsive buying, but the strongest effect occurs indirectly via hedonistic shopping values. Compulsive buyers appear to shop obsessively not only out of their materialistic orientations, but also out of hedonic joy, pleasure, and the 'emotional euphoria' they obtain during shopping. An in‐depth examination between female and male consumers revealed group differences such that the tendency to compulsively buy, which assumed a joint influence of materialism and hedonistic shopping values, is stronger in women than men. Results of this study are discussed in terms of gender and cross‐cultural differences and their theoretical and practical importance to understanding compulsive buying.
Effects of mindfulness‐based interventions on psychological distress and mindfulness in incarcerated populations: A systematic review and meta‐analysis
Authors: Han Areum 
Published: February 2022

AbstractBackgroundAs incarcerated populations report significantly higher prevalence rates for psychological distress than community populations, it is important to have an evidence‐based perspective on what reduces psychological distress among people in prison or jail.AimsTo examine effects of mindfulness‐based interventions (MBIs) on psychological distress, including anxiety, depressive symptoms, stress and overall psychological distress, and on mindfulness in incarcerated populations.MethodsThis systematic review and meta‐analysis of randomised controlled trials (RCTs) involved a comprehensive search within the PubMed, CINAHL, PsycINFO, and SCOPUS databases to identify relevant RCTs. The quality of the included RCTs was assessed using the Cochrane Collaboration risk of bias tool. Depending on I2 statistic values for heterogeneity, either a random effects model or fixed effects model was used. Subgroup analyses for each outcome were conducted to see whether effects differed when compared MBIs to active control groups, provided with other comparable interventions, or passive control groups, provided with no intervention (i.e., treatment as usual [TAU] control groups or waiting list controls).ResultsThirteen RCTs met the eligibility criteria. Meta‐analyses showed moderate effects of MBIs on depressive symptoms and overall psychological distress, large effects on stress, and small effects on anxiety and mindfulness. The overall risk of bias across studies was unclear. Fewer studies were conducted to compare effects of MBIs to other interventions than TAU.ConclusionsFuture high‐quality studies comparing MBIs to other active interventions are needed to understand better whether the former are comparable or superior to other evidence‐based treatments in decreasing distress and improving mindfulness in incarcerated populations and/or in which circumstances one may be preferable to the other.

Using poly(acrylamide‐co‐lauric acid) to remediate oil spills on water
Authors: da Silva Marco A. , Soares João B. P. 
Published: February 2022

AbstractMany methods have been used to reduce the destructive impact of oil spills on the environment. Herding agents added to the periphery of an oil slick cause it to contract into a thicker oil layer with a more uniform thickness covering a much smaller area, thus making it easier to remove the oil by mechanical means or by in situ burning. In this article, we evaluated how a series of poly(acrylamide‐co‐lauric acid) copolymers performed as chemical herders for oil spills. These polymers were tested with diluted bitumen spilled on fresh and artificial seawater. An increase in oil slick thickness of 363% was observed for the copolymer made with an acrylamide/lauric acid ratio of 70/30 in less than 10 min for a loading of 5 g polymer/100 g diluted bitumen. In addition, the final thickness of about 3.0 mm was higher than the requirement to initiate and maintain in situ burning. These easy‐to‐make and inexpensive poly(acrylamide‐co‐lauric acid) copolymers are attractive compounds for the remediation of oil spills.

Published: February 2022

AbstractThe randomness, diversity, and complexity of the high‐speed particle crushing process bring great difficulties to the theoretical analysis of powder engineering. In this paper, the discrete element method is used to simulate the collision of spherical particles, which provides a reference for studying the process and mechanism of crushing between particles under impact load. The Hertz–Mindlin with bonded contact model is used as the particle–particle contact model. The central collisions of particles with different diameter ratios under different high‐speed motions and the eccentric collisions with different eccentricities are discussed. The results show that the bond damage increases with the increase of relative velocity in both centre impact and eccentric impact. In centre collisions, particles of smaller objects are more fragmented than particles of larger objects. For smaller target particles, the larger the diameter ratio is, the more particle elements are detached from the target particles, and the greater the bond breakage rate. For larger target particles, the larger the diameter ratio is, the less the particle element falls off and the smaller the bond breakage rate. This provides guidance for the collision and crushing of particles with different particle size ratios and different eccentricities during high‐speed motion in engineering applications in the future.

AbstractBackgroundMelatonin, the major secretion of the pineal gland, has beneficial effects on the cardiovascular system and might advantage heart failure with reduced ejection fraction (HFrEF) by attenuating the effects of the renin–angiotensin–aldosterone and sympathetic system on the heart besides its antioxidant and anti‐inflammatory effects.HypothesisWe hypothesized that oral melatonin might improve echocardiographic parameters, serum biomarkers, and a composite clinical outcome (including quality of life, hospitalization, and mortality) in patients with HFrEF.MethodsA placebo‐controlled double‐blinded randomized clinical trial was conducted on patients with stable HFrEF. The intervention was 10 mg melatonin or placebo tablets administered every night for 24 weeks. Echocardiography and measurements of N‐terminal pro‐B‐type natriuretic peptide (NT‐Pro BNP), high‐sensitivity C‐reactive protein, lipid profile, and psychological parameters were done at baseline and after 24 weeks.ResultsOverall, 92 patients were recruited, and 85 completed the study (melatonin: 42, placebo: 43). Serum NT‐Pro BNP decreased significantly in the melatonin compared with the placebo group (estimated marginal means for difference [95% confidence interval]: 111.0 [6.2–215.7], p = .044). Moreover, the melatonin group had a significantly better clinical outcome (0.93 [0.18–1.69], p = .017), quality of life (5.8 [0.9–12.5], p = .037), and New York Heart Association class (odds ratio: 12.9 [1.6–102.4]; p = .015) at the end of the trial. Other studied outcomes were not significantly different between groups.ConclusionsOral melatonin decreased NT‐Pro BNP and improved the quality of life in patients with HFrEF. Thus it might be a beneficial supplement in HFrEF.
