Published: June 2023

Aims: Effect of tree species composition and food selectivity on the population density of the Sclater’s guenon was carried out to determine how habitat composition and food preferences affect population density of the Sclater’s monkeys in the study area.
Place and Duration of Study: The study was carried out in forest patches of Lagwa community in Aboh-Mbaise Local Government Area, Imo State (December 2019-November 2021).
Study Design: The point centered quarter method was used to collect data on trees species, while the visual observation and line transect methods was used to collect data on food preference and population density of the monkeys.
Methodology: The research was carried out within the wet and dry season. Faecal examination was used for collecting information on plant and fruit species consumed.
Results: The most dominant tree species were Khaya ivorensis and Treculia africana with important value index (IVI) of 35.13 and 26.73 respectively, while Bosqueia angolensis was the least dominant species with IVI of 0.99. Tree species with diameter at breast height class of 41cm and above were absent in Eziudo, Obo and Umunekere communities. Dacryodes edulis, Elaeis guinensis, Mangifera indica and Musa balbisiana were the most consumed plant species. The mean troop sizes were 3.21±1.42 for the dry season and 2.78±1.25 for the wet season, with troop density for both seasons as 0.03±0.02.
Conclusion: The findings presents the relationship between the Sclater’s monkey’s diet and their habitat, and how habitat changes can cause changes in the feeding pattern, type of food and meals consumed. Sensitization campaigns and provision of alternative food sources for humans can reduce disturbance of the habitat and further sustain the population of the monkeys.

Published: June 2023

AbstractHerein, a self‐charging mechanism of rechargeable aluminum (Al) batteries with Chevrel phase molybdenum sulfide (Mo6S8) cathode is reported. The results unambiguously reveal that the self‐charging is a spontaneous disproportionation of Al intercalated Mo6S8 originated from the dynamic shift of Al between occupied sites during Al intercalating and resting. The theoretical study indicates that the fully Al intercalated Mo6S8 in the format of Al4/3Mo6S8 is kinetically accessible driven by electrochemical overpotential but thermodynamically unstable due to the repulsion between Al3+ cations. This mechanism is a true self‐charging with no input of any form of energy, thus distinctly superior to the previously reported self‐charging mechanisms. Based on this discovery, a semi‐flow AlMo6S8 battery is designed and demonstrated with long‐lasting discharge capability and high capacity.

AbstractThe design of pseudocapacitive electrodes that exhibit high‐rate and high volumetric capacitances is a big challenge, since it requires subtle modulation of ion‐intercalation structures that are able to achieve high electrochemical activity, fast ion transport, and facilitated electron transfer, simultaneously. Herein, controllable and selective etching of B atoms from B‐doped Ti3AlC2 precursors is reported, which generates boron‐vacancy doped MXene (B‐V‐MXene) nanosheets with finely‐regulated, ion‐intercalation structures. Electrochemical studies and density‐functional‐theory calculations demonstrate that Ti around vacancies possess higher surface‐redox activity with protons than those on pristine MXenes for the improvement of capacitances. In addition, interlayer spacing can be optimized on B‐V‐MXenes in promoting proton intercalation. More importantly, the dopant B atoms can increase the electron density on Ti, facilitating the adsorption of the intercalated protons; and further, B 2p‐Ti 3d hybridized band sits closer to the Fermi energy than that of C 2p bands, which bridges the energy gap for electron transfer in the pseudo‐capacitive reaction. With synergy of all these effects, the novel B‐V‐MXene compact electrodes can deliver the previously unmatched high volumetric capacitances of 807 F cm−3 at 1,000 mV s−1 and 1,815 F cm−3 at 5 mV s−1, with excellent cycle stability over 10,000 cycles.

Published: June 2023

AbstractPhotothermal conversion, heat localization and water supply are the keys to achieving efficient solar‐driven interfacial evaporation. However, effective coupling between the three aspects at the air/liquid interface remains challenging. Herein, Au@Ag‐Pd trimetallic nanostructure/polystyrene (PS) microsphere Janus structures are designed as the solar absorber and thermal insulator. The Janus structures deposited on a water supply layer act as a 2D interfacial solar evaporator. The PS microsphere localizes heat at micrometer scale and enhances plasmonic absorption of the Au@Ag‐Pd nanocrystals supported on the microsphere. Meanwhile, the Janus structures divide the surface of water supply layer into multiple regions with sub‐micrometer depths, lowering the evaporation enthalpy. Owing to the synergic effects of these components, the evaporator realizes a solar‐to‐vapor conversion efficiency of 99.1% and an evaporation rate of 3.04 kg m−2 h−1 in pure water under 1 sun illumination. The efficient solar‐driven evaporation can last for over 40 h. Furthermore, the solar evaporator shows high‐performance seawater desalination with salt removal ratios of near 100%. This study brings new insights for controlling evaporation thermodynamics and kinetics. The Janus nano‐micro structure design can be extended to other systems for various solar‐thermal applications.
Granular Hydrogels in Biofabrication: Recent Advances and Future Perspectives
Authors: Daly Andrew C. 
Published: June 2023

AbstractGranular hydrogels, which are formed by densely packing microgels, are promising materials for bioprinting due to their extrudability, porosity, and modularity. However, the multidimensional parameter space involved in granular hydrogel design makes material optimization challenging. For example, design inputs such as microgel morphology, packing density, or stiffness can influence multiple rheological properties that govern printability and the behavior of encapsulated cells. This review provides an overview of fabrication methods for granular hydrogels, and then examines how important design inputs can influence material properties associated with printability and cellular responses across multiple scales. Recent applications of granular design principles in bioink engineering are described, including the development of granular support hydrogels for embedded printing. Further, the paper provides an overview of how key physical properties of granular hydrogels can influence cellular responses, highlighting the advantages of granular materials for promoting cell and tissue maturation after the printing process. Finally, potential future directions for advancing the design of granular hydrogels for bioprinting are discussed.

Published: June 2023

AbstractAs an efficient alternative for harnessing the energy from human's biofluid, a wearable energy harvesting–storage hybrid supercapacitor–biofuel cell (SC‐BFC) microfluidic system is established with one multifunctional electrode. The electrode integrates metal–organic framework (MOF) derived carbon nanoarrays with embedded Au, Co nanoparticles on a flexible substrate, and is used for the symmetric supercapacitor as well as the enzyme nanocarriers of the biofuel cell. The electrochemical performance of the proposed electrode is evaluated, and the corresponding working mechanism is studied in depth according to the cyclic voltammetry and density functional theory calculation. The multiplexed microfluidic system is designed to pump and store natural sweat to maintain the continuous biofuel supply in the hybrid SC‐BFC system. The biofuel cell module harvests electricity from lactate in sweat, and the symmetric supercapacitor module accommodates the bioelectricity for subsequent utilization. A numerical model is developed to validate the normal operation in poor and rich sweat under variable situations for the microfluidic system. One single SC‐BFC unit can be self‐charged to ≈0.8 V with superior mechanical durability in on‐body testing, as well as energy and power values of 7.2 mJ and 80.3 µW, respectively. It illustrates the promising scenery of energy harvesting–storage hybrid microfluidic system.

AbstractFor bone defect repair, it is critical to utilize biomaterials with pro‐angiogenic properties to enhance osteogenesis. Hydroxyapatite (HA)‐based materials widely used in clinical applications have shown much potential for bone repair. However, their predominant calcium phosphate (CaP) composition and poor biodegradability limit their angiogenic potential and hence osteogenic efficiency of HA‐based materials. Here, a magnesium ion‐doped calcium silicate/HA composite microscaffold (Mg‐CS/HA) is fabricated to enhance angiogenesis and osteogenic efficiency for bone repair. Incorporation of CS improved the biodegradability of the Mg‐CS/HA microscaffold, which could simultaneously release Si and Mg bioactive ions during the early stage of implantation, synergistically enhancing angiogenesis and osteogenic efficiency. In co‐culture systems, the synergistic effects of Si and Mg ions promote the “osteogenesis‐angiogenesis coupling effect.” In vivo, the Mg‐CS/HA microscaffold could significantly promote reconstruction of the vascular network and bone regeneration. This study thus provides a new strategy for coordinated release of bioactive ions to achieve synergistic effects on vascularized bone regeneration by HA‐based bone implant materials.

Published: June 2023

AbstractPrinting or patterning particle‐based liquid metal (LM) ink is a good strategy to overcome poor wettability of LM for its circuits’ preparation in flexible and printed electronics. Subsequently, a crucial step is to recover conductivity of LM circuits consisting of insulating LM micro/nano‐particles. However, most widely used mechanical sintering methods based on hard contact such as pressing, may not be able to contact the LM patterns' whole surface conformally, leading to insufficient sintering in some areas. Hard contact may also break delicate shapes of the printed patterns. Hereby, an ultrasonic‐assisted sintering strategy that can not only preserve original morphology of the LM circuits but also sinter circuits on various substrates of complex surface topography is proposed. The influencing factors of the ultrasonic sintering are investigated empirically and interpreted with theoretical understanding by simulation. LM circuits encapsulated inside soft elastomer are successfully sintered, proving feasibility in constructing stretchable or flexible electronics. By using water as energy transmission medium, remote sintering without any direct contact with substrate is achieved, which greatly protect LM circuits from mechanical damage. In virtue of such remote and non‐contact manipulation manner, the ultrasonic sintering strategy would greatly advance the fabrication and application scenarios of LM electronics.

Published: June 2023

AbstractPremiseMany tropical plants are bat‐pollinated, but these mammals often carry copious, multispecific pollen loads making bat‐pollinated plants susceptible to heterospecific pollen deposition and reproductive interference. We investigated pollen transfer between sympatric bat‐pollinated Burmeistera species and their response to heterospecific pollen deposition from each other.MethodsWe quantified conspecific and heterospecific pollen deposition for two populations of B. ceratocarpa, a recipient species in heterospecific pollen transfer interactions, that co‐occur with different donor relatives (B. borjensis and B. glabrata). We then used a cross‐pollination scheme using pollen mixtures to assess the species' responses to heterospecific pollen deposition in terms of fruit abortion and seed production.ResultsBurmeistera ceratocarpa received significantly more heterospecific pollen from its relatives at both sites than its own pollen was deposited on its relatives. However, heterospecific pollen deposition only affected seed production by B. borjensis and B. glabrata, but not by B. ceratocarpa, suggesting that early acting post‐pollination barriers buffer the latter against reproductive interference. Crosses between sympatric and allopatric populations suggest that the study species are fully isolated in sympatry, while isolation between allopatric populations is strong but incomplete.ConclusionsWe did not observe evidence of reproductive interference among our study species, because either heterospecific pollen deposition did not affect their seed production (B. ceratocarpa) or they receive heterospecific pollen only rarely (B. borjensis and B. glabrata). Frequent heterospecific pollen deposition might favor the evolution of barriers against foreign pollen (as in B. ceratocarpa) that alleviate the competitive costs of sharing low fidelity pollinators with co‐occurring species.

AbstractBackgroundSeveral biological processes are regulated by miR‐200a‐3p, including cell proliferation, migration, and epithelial–mesenchymal transition (EMT). In this study we aimed to uncover the diagnostic value and molecular mechanisms of miR‐200a‐3p in chronic rhinosinusitis with nasal polyps (CRSwNP).MethodsThe expressions of miR‐200a‐3p were detected by quantitative real‐time polymerase chain reaction (qRT‐PCR), Zinc finger E‐box binding homeobox 1 (ZEB1) levels were examined by qRT‐PCR and immunofluorescence staining. The interaction between miR‐200a‐3p and ZEB1 was predicted by TargetScan Human 8.0 and confirmed by dual‐luciferase reporter assays. In addition, the effect of miR‐200a‐3p and ZEB1 on EMT‐related makers and inflammation cytokines was assessed by qRT‐PCR and Western blotting in human nasal epithelial cells (hNEpCs) and primary human nasal mucosal epithelial cells (hNECs).ResultsWe found that miR‐200a‐3p was downregulated in non‐eosinophilic and eosinophilic CRSwNP patients when compared with controls. The diagnostic value of miR‐200a‐3p in serum is reflected by the receiver operating characteristic curve and the 22‐item Sino‐Nasal Outcome Test. Bioinformatic analysis and luciferase reporter assay identified ZEB1 as a target of miR‐200a‐3p. ZEB1 was more highly expressed in CRSwNP than in controls. Furthermore, miR‐200a‐3p inhibitor or ZEB1 overexpression significantly suppressed the epithelial marker E‐cadherin; promoted the activation of vimentin, α‐spinal muscle atrophy, and N‐cadherin; and aggravated inflammation in hNEpCs. Knockdown of ZEB1 significantly alleviated the cellular remodeling caused by miR‐200a‐3p inhibitor via the extracellular signal‐regulated kinase (ERK)/p38 pathway in hNECs.ConclusionsmiR‐200a‐3p suppresses EMT and inflammation by regulating the expression of ZEB1 via the ERK/p38 pathway. Our study presents new ideas for protecting nasal epithelial cells from tissue remodeling and finding a possible target for disease.

Published: June 2023

AbstractIn situ pyroelectric calorimetry and spectroscopic ellipsometry were used to investigate surface reactions in atomic layer deposition (ALD) of zirconium oxide (ZrO2). Calibrated and time‐resolved in situ ALD calorimetry provides new insights into the thermodynamics and kinetics of saturating surface reactions for tetrakis(dimethylamino)zirconium(IV) (TDMAZr) and water. The net ALD reaction heat ranged from 0.197 mJ cm−2 at 76 °C to 0.155 mJ cm−2 at 158 °C, corresponding to an average of 4.0 eV/Zr at all temperatures. A temperature dependence for reaction kinetics was not resolved over the range investigated. The temperature dependence of net reaction heat and distribution among metalorganic and oxygen source exposure is attributed to factors including growth rate, equilibrium surface hydroxylation, and the extent of the reaction. ZrO2‐forming surface reactions were investigated computationally using DFT methods to better understand the influence of surface hydration on reaction thermodynamics.

Published: June 2023

AbstractAntimony corrole cations have been prepared by one‐electron oxidation of antimony(III) congeners with silver(I) and copper(II) salts. Isolation and crystallization was successful for the first time, and the X‐ray crystallographic investigation unraveled structural similarities with antimony(III)corroles. EPR experiments showed strong hyperfine interactions of the unpaired electron with the 121Sb (I=5/2) and 123Sb nuclei (I=7/2). A DFT analysis supports the description of the oxidized form as a SbIII corrole radical with less than 2 % SbIV character. In the presence of water or a fluoride source like PF6−, the compounds undergo a redox disproportionation to yield known antimony(III)corroles and either difluorido‐antimony(V)corroles, or bis‐μ‐oxido‐di[antimony(V)corroles] via novel cationic hydroxo‐antimony(V) derivatives.

Published: June 2023

AbstractPiezo‐catalytic self‐Fenton (PSF) system has been emerging as a promising technique for wastewater treatment, while the competing O2 reductive hydrogen peroxide (H2O2) production and FeIII reduction seriously limited the reaction kinetics. Here, we develop a two‐electron water oxidative H2O2 production (WOR−H2O2) coupled with FeIII reduction over a FeIII/BiOIO3 piezo‐catalyst for highly efficient PSF. It is found that the presence of FeIII can simultaneously initiate the WOR−H2O2 and reduction of FeIII to FeII, thereby enabling a rapid reaction kinetics towards subsequent Fenton reaction of H2O2/FeII. The FeIII initiating PSF system offers exceptional self‐recyclable degradation of pollutants with a degradation rate constant for sulfamethoxazole (SMZ) over 3.5 times as that of the classic FeII‐PSF system. This study offers a new perspective for constructing efficient PSF systems and shatters the preconceived notion of FeIII in the Fenton reaction.

Published: June 2023

AbstractWe disclose a Ni‐catalyzed regioselective dialkylation reaction of alkenylarenes with α‐halocarbonyls and alkylzinc reagents. The reaction produces γ‐arylated alkanecarbonyl compounds with the generation of two new C(sp3)−C(sp3) bonds at the vicinal carbons of alkenes. This reaction is effective for the use of primary, secondary and tertiary α‐halocarboxylic esters, amides and ketones in conjunction with primary and secondary alkylzinc reagents as the sources of two C(sp3) carbons for the dialkylation of terminal and cyclic internal alkenes.
