Published: October 2023

AbstractIn the past decade, micro‐ and nanomachines (MNMs) have made outstanding achievements in the fields of targeted drug delivery, tumor therapy, microsurgery, biological detection, and environmental monitoring and remediation. Researchers have made significant efforts to accelerate the rapid development of MNMs capable of moving through fluids by means of different energy sources (chemical reactions, ultrasound, light, electricity, magnetism, heat, or their combinations). However, the motion of MNMs is primarily investigated in confined two‐dimensional (2D) horizontal setups. Furthermore, three‐dimensional (3D) motion control remains challenging, especially for vertical movement and control, significantly limiting its potential applications in cargo transportation, environmental remediation, and biotherapy. Hence, an urgent need is to develop MNMs that can overcome self‐gravity and controllably move in 3D spaces. This review delves into the latest progress made in MNMs with 3D motion capabilities under different manipulation approaches, discusses the underlying motion mechanisms, explores potential design concepts inspired by nature for controllable 3D motion in MNMs, and presents the available 3D observation and tracking systems.

AbstractPhase transformation of cobalt selenide (CoSe2) can effectively modulate its intrinsic electrocatalytic activity. However, enhancing electroconductivity and catalytic activity/stability of CoSe2 still remains challenging. Heterostructure engineering may be feasible to optimize interfacial properties to promote the kinetics of oxygen electrocatalysis on a CoSe2‐based catalyst. Herein, a heterostructure consisting of CoSe2 and cobalt nitride (CoN) embedded in a hollow carbon cage is designed via a simultaneous phase/interface engineering strategy. Notably, the phase transition of orthorhombic‐CoSe2 to cubic‐CoSe2 (c‐CoSe2) accompanied by in situ CoN formation is realized to build the c‐CoSe2/CoN heterointerface, which exhibits excellent/highly stable activities for oxygen reduction/evolution reactions (ORR/OER). Notably, heterostructure can modulate the local coordination environment and increase Co‐Se/N bond lengths. Theoretical calculations show that Co‐site (c‐CoSe2) with an electronic state near Fermi energy level is the main active site for ORR/OER.Energetical tailoring of the d‐orbital electronic structure of the Co atom of c‐CoSe2 in heterostructure by in situ CoN incorporation lowers thermodynamic barriers for ORR/OER. Attractively, a zinc‐air battery with a c‐CoSe2‐CoN cathode displays excellent cycling stability (250 h) and charge/discharge voltage loss (0.953/0.96 V). It highlights that heterointerface engineering provides an option for modulating the bifunctional activity of metal selenides with controlled phase transformation.

Published: October 2023

AbstractZeolites are highly efficient industrial catalysts and sorbents with microporous framework structures. Approximately 10% of the frameworks, but eventually all in the long run, have produced both 3D crystals and 2D layers. The latter can be intercalated and expanded like all 2D materials but proved difficult to exfoliate directly into suspensions of monolayers in solution as precursors for unique synthetic opportunities. Successful exfoliations have been reported recently and are overviewed in this perspective article. The discussion highlights 3 primary challenges in this field, namely finding suitable 2D zeolite preparations that exfoliate directly in high yield, proving uniform layer thickness in solution and identifying applications to exploit the unique synthetic capabilities and properties of exfoliated zeolite monolayers. Four zeolites have been confirmed to exfoliate directly into monolayers: 3 with known structures—MWW, MFI, and RWR and one unknown, bifer with a unit cell close to ferrierite. The exfoliation into monolayers is confirmed by the combination of 5–6 characterization techniques including AFM, in situ and in‐plane XRD, and microscopies. The promising areas of development are oriented films and membranes, intimately mixed zeolite phases, and hierarchical nanoscale composites with other active species like nanoparticles and clusters that are unfeasible by solid state processes.

Published: October 2023

AbstractNanozymes are considered as the promising antimicrobial agents due to the enzyme‐like activity for chemo‐dynamic therapy (CDT). However, it remains a challenge to develop novel nanozyme systems for achieving stimuli‐responsive, and efficient nanozyme catalysis with multimodal synergistic enhancement. In this work, a near‐infrared (NIR) plasmonic‐enhanced nanozyme catalysis and photothermal performance for effective antimicrobial applications are proposed. A Ti3C2 MXene/Fe‐MOFs composite (MXM) with NIR plasmonic‐enhanced CDT combined with photothermal properties is successfully developed by loading metal‐organic framework (MOF) nanozymes onto Ti3C2 MXene. The mechanism of NIR induced localized surface plasmon resonance (LSPR)‐enhanced CDT and photothermal therapy (PTT) is well explained through activation energy (Ea), electrochemical impedance spectroscopy (EIS), X‐ray photoelectron spectroscopy (XPS), fluorescence analysis experiments, and finite element simulation. It reveals that MXene nanosheets exhibit NIR plasmon exciters and generate hot electrons that can transfer to the surface of Fe‐MOFs, promoting the Fenton reaction and enhances CDT. While the photothermal heating of MXene produced by LSPR can also boost the CDT of Fe‐MOFs under NIR irradiation. Both in vitro and in vivo experimental results demonstrate that LSPR‐induced MXM system has outstanding antimicrobial properties, can promote angiogenesis and collagen deposition, leading to the accelerated wound healing.

Published: October 2023

AbstractPhotocatalytic cellulose reforming usually requires harsh conditions due to its sluggish kinetics. Here, a hollow structural S‐scheme heterojunction of ZnSe and oxygen vacancy enriched TiO2, namely, h‐ZnSe/Pt@TiO2, is designed and fabricated, with which the photocatalytic reforming of cellulose for H2 and formic acid is realized in pure water. H2 and formic acid productivity of 1858 and 372 µmol g−1 h−1 and a steady H2 evolution for 300 h are achieved with α‐cellulose. Comparable photocatalytic activity can also be achieved using various cellulose sources. It is experimentally proven that the photogenerated charge transfer follows an S‐scheme mechanism, which not only promotes the charge separation but also preserves the higher reductive and oxidative abilities of the ZnSe and TiO2, respectively. Furthermore, the polyhydroxy species produced during cellulose degradation are favored to adsorb on the oxygen vacancy enriched TiO2 surface, which promotes the photocatalytic reforming process and is accounted to the preservation of formic acid as the major solution‐phase product. In addition, sequential reactions of oxidation of aldehydes and elimination of formic acid of the cellulose degradation process are revealed. This work provides a photocatalytic strategy to sustainably produce hydrogen and value‐added chemicals from biomass under the most environmentally benign condition, i.e., pure water.

Published: October 2023

AbstractIn Chile, there are no validated instruments for the evaluation of quality of life (QoL) of people with Down syndrome (DS). To analyze construct validity and reliability of the KidsLife‐Down scale in Chile to measure QoL in people with DS aged from 4 to 21 years. Families of boys, girls, and young people with DS between 4 and 21 years were invited to participate. The scale was answered by relatives or caregivers. To assess the internal consistency, reliability tests were performed using Cronbach's alpha coefficient. A confirmatory factor analysis was performed. The scale was answered by 531 relatives or caregivers. Cronbach's coefficient was greater than 0.7 in all the items. The confirmatory factor analysis of the scale allowed its validation for clinical use in the Chilean population. “Kids Life Down‐Chile” scale has adequate psychometric properties to be used in clinical practice and to help us improve QoL with better support strategies.

AbstractBackgroundWe describe a case of segmental arterial mediolysis in which a vessel ruptured on two consecutive days.Case PresentationA 69‐year‐old man presented with sudden‐onset abdominal pain. Computed tomography showed a hematoma in the gastric wall. The patient was discharged after the pain was relieved but returned 8 h later with abdominal pain and shock. Repeated computed tomography revealed a massive intra‐abdominal hemorrhage without previous aneurysm formation. Emergency angiography and coil embolization were successfully carried out. Segmental arterial mediolysis was diagnosed after irregular vasodilated lesions were observed in multiple arteries.ConclusionThis case suggests that accurately predicting the next vessel rupture is difficult. For patients experiencing intra‐abdominal bleeding with segmental arterial mediolysis, we suggest treating only ruptured aneurysms and closely following‐up unruptured aneurysms.
New Frontiers in Organosodium Chemistry as Sustainable Alternatives to Organolithium Reagents
Authors: Anderson David E. , Tortajada Andreu , Hevia Eva 
Published: October 2023

AbstractWith their highly reactive respective C−Na and N−Na bonds, organosodium and sodium amide reagents could be viewed as obvious replacements or even superior reagents to the popular, widely utilised organolithiums. However, they have seen very limited applications in synthesis due mainly to poor solubility in common solvents and their limited stability. That notwithstanding in recent years there has been a surge of interest in bringing these sustainable metal reagents into the forefront of organometallics in synthesis. Showcasing the growth in utilisation of organosodium complexes within several areas of synthetic chemistry, this Minireview discusses promising new methods that have been recently reported with the goal of taming these powerful reagents. Special emphasis is placed on coordination and aggregation effects in these reagents which can impart profound changes in their solubility and reactivity. Differences in observed reactivity between more nucleophilic aryl and alkyl sodium reagents and the less nucleophilic but highly basic sodium amides are discussed along with current mechanistic understanding of their reactivities. Overall, this review aims to inspire growth in this exciting field of research to allow for the integration of organosodium complexes within common important synthetic transformations.

Published: October 2023

Study on uranium adsorption materials is crucial in addressing uranium pollution and safeguarding water resources. In this paper, a novel Ni/Co‐LDH@ZIF‐67/8‐MOF (LDH/MOF) composite was fabricated by loading ZIF‐67/8‐MOF on the surface of Ni/Co‐LDH with silane coupling group as bonding agent. The LDH/MOF composite was tested by XRD, FT‐IR, SEM, TGA, and XPS methods. The LDH/MOF composite exhibited exceptional uranium (U (VI)) adsorption capacity, with the Langmuir isotherm model estimating a maximum adsorption capacity of 617.33 mg/g, and the adsorption process followed quasi‐second‐order kinetics. Notably, ultrasonic mixing achieved equilibrium in a mere 5 minutes, outperforming traditional oscillation mixing by a considerable margin, offering new possibilities for enhancing uranium removal efficiency. Furthermore, thermodynamic analysis revealed the spontaneous and endothermic nature of U (VI) adsorption onto LDH/MOF. In addition, XPS investigations provided valuable insights into the adsorption mechanisms, primarily involving surface complexation, chelation, and ion exchange. These innovative findings open new avenues for the development of highly selective and efficient uranium separation methods, highlighting the promising potential of LDH/MOF as a highly prospective material for uranium separation in diverse applications, including environmental remediation and nuclear waste management.

Published: October 2023

AbstractAll industries depend on natural capital assets and ecosystem services, either directly, through their supply chains, or through their investments. Companies are therefore challenged to reorient their production systems and turn the conservation and sustainable use of biodiversity into an opportunity for sustainable economic development. In this paper, we analyze the interest of institutional investors in these corporate policies through the role they play in the disclosure that companies make about them. For a balanced data panel of 8,320 firm‐year observations from 832 global companies operating in different sectors of activity over the period 2011–2020, the results obtained indicate that institutional investors, especially those with investment a long‐term investment horizon, are interested in biodiversity commitments and exercise their demand for information on these initiatives through their representatives on the board of directors. Furthermore, we show that companies are rewarded for disclosing relevant information on business policies, biodiversity management, and the valuation of ecosystem services in the value chain.

AbstractAlzheimer's disease (AD) is a neurodegenerative disease that occurs especially in advanced ages. It reduces the quality of life of both the patient and their relatives. In addition to its primary effects, AD causes metabolic defects and tissues are damaged due to these effects. Oxidative stress damages cells by disrupting antioxidant/oxidant balance in many tissues, especially due to AD. In individuals with AD and the elderly, lens tissue is damaged due to oxidative stress and may cause vision loss. Therefore, it is very important to investigate herbal products that both prevent/cure AD and reduce AD‐related oxidative stress, as they may have fewer side effects. In this study, the protective effects of parsley (Petroselinum crispum) extract on lens tissues of an experimental AD model induced by scopolamine were examined and evaluated through biochemical parameters. The result of biochemical experiments and principal component analysis, was observed that parsley extract had a therapeutic effect by reducing oxidative stress in lens tissues of experimentally induced AD rats. It can be suggested that the phenolic and flavonoid‐rich content of parsley extract may have caused the reduction of oxidative damage in lens tissues and can be used to protect lens tissue against oxidative stress due to AD disease.

Published: October 2023

AbstractPlastic waste is a promising and abundant resource for H2 production. However, upcycling plastic waste into H2 fuel via conventional thermochemical routes requires relatively considerable energy input and severe reaction conditions, particularly for polyolefin waste. Here, we report a tandem strategy for the selective upcycling of polypropylene (PP) waste into H2 fuel in a mild and clean manner. PP waste was first oxidized into small‐molecule organic acids using pure O2 as oxidant at 190 °C, followed by the catalytic reforming of oxidation aqueous products over ZnO‐modified Ru/NiAl2O4 catalysts to produce H2 at 300 °C. A high H2 yield of 44.5 mol/kgPP and a H2 mole fraction of 60.5 % were obtained from this tandem process. The entire process operated with almost no solid residue remaining and equipment contamination, ensuring relative stability and cleanliness of the reaction system. This strategy provides a new route for low‐temperature transforming PP and improving the sustainability of plastic waste disposal processes.

Authors: Agnihotri Mona , Kothari Kanchan , Monteiro Rashmi 
Published: October 2023

AbstractSubacute granulomatous thyroiditis (SGT)/De Quervain's thyroiditis is a rare self‐limiting inflammatory disease, accounting for 3% of all thyroid disorders. Most commonly seen in middle aged women, it shows a characteristic triad of pain in the anterior cervical region, increased ESR and recent history of viral upper respiratory tract infection. The cytomorphological features are not pathognomonic and can also be seen in Hashimoto's thyroiditis, granulomatous infections, sarcoidosis, and papillary thyroid carcinoma. We report four cases of SGT, diagnosed on fine needle aspiration cytology (FNAC). Familiarity with cytomorphology of SGT and awareness of the clinical setting is essential for making an accurate diagnosis.
The diversity of animals identified as keystone species

Published: October 2023

AbstractAlthough the keystone species concept was conceived of over 50 years ago, contemporary efforts to synthesize related literature have been limited. Our objective was to create a list of keystone animal species identified in the literature and to examine the variation in the traits of species and the ecosystem influences they elicit. We documented 230 species considered keystones. A clustering analysis classified them into five archetypes based on combinations of their taxonomic class, body size, trophic level, and role (consumers, modifiers, or prey). Although conservation and public perception of keystones primarily focuses on large vertebrate consumers, our analysis reveals that researchers have defined a wide diversity of keystone species, with large variation in associated ecosystem processes. Future research may confront ambiguity in the definition of keystone status, as well as clarify the type, abundance, and quality of data required to assign the term. Identifying keystones with increased rigor would not only enrich the literature but also inform intervention to safeguard threatened keystones and their associated influences on ecosystems.

AbstractAimsThis study aimed to study the prognostic value of myocardial oxygen consumption (MVO2) and myocardial external efficiency (MEE) from 11C‐acetate positron emission tomography (PET) in cardiac amyloidosis (CA) patients.Methods and resultsForty‐eight CA patients, both transthyretin (ATTR) and immunoglobulin light chain (AL) amyloidosis, and 20 controls were included. All subjects were examined with 11C‐acetate PET and echocardiography. MVO2, forward stroke volume (FSV), and left ventricular mass (LVM) were derived from 11C‐acetate PET and used to calculate MEE. CA patients were followed for survival and the prognostic impact of clinical, echocardiographic, and 11C‐acetate PET parameters was analysed. MVO2 and MEE were reduced in CA compared with controls, but without significant difference between deceased and surviving CA patients. The ratio of 11C‐acetate PET‐derived FSV and LVM was also reduced in CA and significantly lowered in deceased patients compared with survivors. In univariate analysis, New York Heart Association class, N‐terminal pro‐brain natriuretic peptide, and the 11C‐acetate PET parameters FSV/LVM and MEE were the strongest prognostic factors. Of the 11C‐acetate PET parameters, FSV/LVM was the strongest survival predictor with hazard ratio of 0.56 per 0.1 mL/g (95% confidence interval 0.39–0.81, P = 0.002) and independently prognostic in a multivariate model. MEE significantly separated deceased from surviving CA patients with the cut‐off of 15.7% (P = 0.032). Survival was significantly shorter with FSV/LVM below 0.27 mL/g (P < 0.001), also when separating AL‐ and ATTR‐CA.ConclusionsReduced MEE was associated with shorter survival in CA patients, but FSV/LVM was the strongest survival predictor and the only independently prognostic 11C‐acetate PET parameter in multivariate analysis.
