Published: September 2022

AbstractThe porous polymeric membranes prepared by conventional nonsolvent‐induced phase separation (NIPS) suffer from notorious fouling pollution during oil/water separation. Herein, an improved one‐step NIPS strategy is proposed to fabricate anti‐fouling polyethersulfone (PES) based membranes that bear hierarchically spherical structures on the interface and an internalized gel network. More specifically, the hydrogen bonding between hydrophilic additives of polyvinylpyrrolidone (PVP) and tannic acid (TA), as well as Fe3+‐TA coordination interaction are orchestrated to modulate their surface segregation behaviors during NIPS, leading to in situ generation of the interfacial assembled nanospheres and embedded gel networks in the PES matrix. Thanks to the synergistic effect of these dual antifouling barriers, the optimized membrane exhibits super‐hydrophilic/underwater super‐oleophobic properties, and displays high efficiency as well as good recyclability in separating surfactant stabilized oil‐in‐water emulsions. In addition, this improved NIPS methodology allows dip coating of various porous substrates to separate diverse oil/water mixtures, which also exhibits good anti‐fouling ability. Basically, this study will provide new insights for design of anti‐pollution oil/water separation materials by the phase inversion method.

AbstractAn efficient water oxidation photocatalyst is imperative for the realization of artificial photosynthesis. Herein, a cooperative strategy is represented that enables 2D structure tailoring and lattice distortion engineering simultaneously over a BiVO4 photocatalyst for efficient visible‐light‐driven oxygen evolution reaction (OER). Specifically, the lattice distortion engineering is achieved through the introduction of a sodium (Na+) additive during the ion exchange process. Structural characterizations suggest the formation of ultrathin 2D monoclinic BiVO4 nanoflakes with shrank VO and elongated BiO bonds. Mechanistic investigations reveal the advantages of ultrathin 2D features for exposing more (010) active facets and shortening the required migration distance for charge carriers to reach the catalytic surface. More importantly, the lattice distortion effect is found to crucially govern the charge carrier dynamics and catalytic surface behavior of BiVO4 photocatalyst, endowing the optimized sample with an outstanding photocatalytic OER performance triggering up to 69.4% apparent quantum efficiency over Fe3+ sacrificial solution. These findings highlight the functional application of morphology and dimensional modification, as well as lattice distortion engineering in synthesizing superior monoclinic BiVO4 photocatalyst for efficient visible‐light‐driven water oxidation.

AbstractNerve‐related fluorophores generally locate in the visible or near‐infrared region with shallow penetration depth and easy uptake by surrounding tissues. Prolonging the optical window promotes resolution by minimizing photoscattering and eliminating autofluorescence for NIR‐II (second near infrared; 1000–1700 nm) and photoacoustic bioimaging. In addition, combination of the two could help in colocalization of targets at the 3D level. Catheter‐based renal sympathetic denervation (RDN), an alternative treatment recently finishing its clinical evaluation for treating resistant hypertension, is highly dependent on experience and in urgent demand for in vivo guidance in locating the nerve over the renal artery. Here, an NIR‐II and photoacoustic bioimaging system based on a dye‐modified anti‐tyrosine‐hydroxylase antibody (TH‐ICGM) to illustrate the peritoneal sympathetic nerve‐related region are combined. With high resolution (0.15 mm) in NIR‐II region for both absorbance (λex = 925 nm) and fluorescence (bioimaging in λem ≥ 1300 nm), TH‐ICGM succeeds in providing 3D coordinates of procedure position with a precision in 0.1 mm. As the first nerve‐related NIR‐II immunoprobe, TH‐ICGM has great clinical potential as assistance for nerve‐related interventions.

AbstractFlexible scintillator screens with environmental stability, high sensitivity, and low cost have emerged as candidates for X‐ray imaging applications. Here, a large‐scale and cost‐efficient solution synthesis of the vacancy‐ordered double perovskite Cs2ZrCl6, which is characterized by thermal activation delayed fluorescence (TADF) dominated by triplet emission under X‐ray irradiation, is demonstrated. The large Stokes shift and efficient luminescence collection of TADF effectively ensure the light outcoupling efficiency. Further, flexible X‐ray scintillator screens with an area of 400 cm2 are prepared using poly(dimethylsiloxane) (PDMS) as the carrier, exhibiting excellent scintillation properties with light yields as high as 49 400 photons MeV−1, spatial resolutions up to 18 lp mm−1 and detection limits as low as 65 nGy s−1. Finally, the high‐quality imaging results of non‐planar and dynamic objects by such screens are demonstrated. It is believed that the explored Cs2ZrCl6@PDMS flexible scintillator screens would offer a big step toward expanding the application range of scintillators in different environments.

AbstractSensory nerves are long being recognized as collecting units of various outer stimuli; recent advances indicate that the sensory nerve also plays pivotal roles in maintaining organ homeostasis. Here, this study shows that sensory nerve orchestrates intervertebral disc (IVD) homeostasis by regulating its extracellular matrix (ECM) metabolism. Specifically, genetical sensory denervation of IVD results in loss of IVD water preserve molecule chondroitin sulfate (CS), the reduction of CS bio‐synthesis gene chondroitin sulfate synthase 1 (CHSY1) expression, and dysregulated ECM homeostasis of IVD. Particularly, knockdown of sensory neuros calcitonin gene‐related peptide (CGRP) expression induces similar ECM metabolic disorder compared to sensory nerve denervation model, and this effect is abolished in CHSY1 knockout mice. Furthermore, in vitro evidence shows that CGRP regulates nucleus pulposus cell CHSY1 expression and CS synthesis via CGRP receptor component receptor activity‐modifying protein 1 (RAMP1) and cyclic AMP response element‐binding protein (CREB) signaling. Therapeutically, local injection of forskolin significantly attenuates IVD degeneration progression in mouse annulus fibrosus puncture model. Overall, these results indicate that sensory nerve maintains IVD ECM homeostasis via CGRP/CHSY1 axis and promotes IVD repair, and this expands the understanding concerning how IVD links to sensory nerve system, thus shedding light on future development of novel therapeutical strategy to IVD degeneration.

AbstractIt remains unclear to what extent cerebrovascular burden relates to amyloid beta (Aβ) deposition, neurodegeneration, and cognitive dysfunction in mixed disease populations with small vessel disease and Alzheimer's disease (AD) pathology. In 120 subjects, we investigated the association of vascular burden (white matter hyperintensity [WMH] volumes) with cognition. Using mediation analyses, we tested the indirect effects of WMH on cognition via Aβ deposition (18F‐AV45 positron emission tomography [PET]) and neurodegeneration (cortical thickness or 18F fluorodeoxyglucose PET) in AD signature regions. We observed that increased total WMH volume was associated with poorer performance in all tested cognitive domains, with the strongest effects observed for semantic fluency. These relationships were mediated mainly via cortical thinning, particularly of the temporal lobe, and to a lesser extent serially mediated via Aβ and cortical thinning of AD signature regions. WMH volumes differentially impacted cognition depending on lobar location and Aβ status. In summary, our study suggests mainly an amyloid‐independent pathway in which vascular burden affects cognitive function via localized neurodegeneration.Highlights
Alzheimer's disease often co‐exists with vascular pathology.
We studied a unique cohort enriched for high white matter hyperintensities (WMH).
High WMH related to cognitive impairment of semantic fluency and executive function.
This relationship was mediated via temporo‐parietal atrophy rather than metabolism.
This relationship was, to lesser extent, serially mediated via amyloid beta and atrophy.
Local ecological knowledge from Andros Island, The Bahamas, reveals new insights on the distribution and use of the Critically Endangered smalltooth sawfish, Pristis pectinata

Abstract

The Bahamas is among the last remaining refuges for the Critically Endangered smalltooth sawfish, Pristis pectinata, and the presence of a distinct ‘beacon of hope’ population on Andros Island may prove critical to their recovery. Although legislation in The Bahamas protects sharks from exploitation, no such national protection exists for rays, which include sawfishes. Targeted efforts to protect essential habitats coupled with community‐led conservation actions provide a path forward for sawfish conservation and recovery.
Structured interviews were conducted in 2021 (n = 77) with community members that frequent Andros waters to describe the temporal and spatial patterns of sawfish distribution in Andros, and to identify key regions or habitats for sawfish‐specific monitoring and potential protection.
Sawfish encounters (n = 99) included all life stages and were located throughout coastal and tidal waters of Andros. Comparable numbers of animals were encountered along both coastlines, predominantly on shallow (<2 m), muddy flats close to shore (<1 km). Most notable were encounters with young‐of‐the‐year sawfishes in new regions of Andros, indicating the potential discovery of undocumented nursery habitats. Although most encounters were sightings, 22% (n = 20) of the sawfishes were caught, with just under half of these harvested for food, bait, and/or to keep the rostrum as a decorative item.
There is an urgent need for more expansive protection and monitoring of smalltooth sawfishes across their range in Andros and improved education and outreach to prevent further harvest. Recommendations include: (i) the formal development of a national strategy for sawfish conservation; (ii) adding sawfish to the existing shark sanctuary to provide national protective measures; and (iii) community‐led outreach and education activities to develop and lead conservation initiatives, including ecotourism and wildlife guiding and a Bahamian sawfish reporting network.

Published: August 2022

AbstractLithium‐oxygen batteries have received great research interest owing to their ultrahigh theoretical energy density and are considered as one of the promising secondary batteries. However, there are still some challenges in their practical application, like liquid organic electrolyte evaporation in the semi‐open system and instability in the high‐voltage oxidizing environment. In this work, a cellulose acetate‐based gel polymer electrolyte (CA@GPE) is proposed, whose cross‐linked microporous structure ensures the ultrahigh liquid electrolyte uptake of 2391%. The prepared CA@GPE exhibits a high lithium‐ion transference number of 0.595, a satisfying ionic conductivity of 0.47 mS cm−1 and a wide electrochemical stability window up to 5.0 V. The Li//Li symmetric cell employing CA@GPE could cycle stably over 1200 h. The lithium‐oxygen battery with CA@GPE presents a superb cycling lifetime of 370 cycles at 0.1 mA cm−2 under 0.25 mAh cm−2. This work offers a possible strategy to realize long‐cycling stability lithium‐oxygen batteries.
Recent Advances in Transition‐Metal‐Catalyzed C−H Functionalization of Ferrocene Amides
Authors: Mou Qi , Zhao Ruyuan , Sun Bo 
Published: September 2022

AbstractDuring the past decades, in synthetic organic chemistry, directing‐group‐assisted C−H functionalization is found to be a key tool for the expedient and site‐selective construction of C−C and hybrid bonds. Among C−H functionalization of ferrocene derivatives, the directed group strategy is undoubtedly the most commonly used method. Compared to the other directing groups, ferrocene amides can be synthesized easily and are now recognized as one of the most efficient tools for the selective functionalization of certain positions because its metal centre permits fine, tuneable and reversible coordination. The family of amide directing groups mainly comprises monodentate and bidentate directing groups, which are categorized on the basis of coordination sites. In this review, various C−H bond functionalization reactions of ferrocene using amide directing groups are broadly discussed.

The implications of geopolitical, socioeconomic, and regulatory constraints on European bioenergy imports and associated greenhouse gas emissions to 2050

Published: August 2022

AbstractModern sustainable bioenergy can contribute toward mid‐century European energy decarbonization targets by replacing fossil fuels. Fulfilling this role would require access to increased volumes of bioenergy, with extra‐EU imports projected to play an important part. Access to this resource on the international marketplace is not governed by Europe's economic competitiveness alone. This study investigates geopolitical, socioeconomic, and regulatory considerations that can influence Europe's bioenergy imports but that are so far underexplored. The effect of these constraints on European import volumes, sourcing regions, mitigation potential, and their implications for European and global emissions is projected to the year 2050 using a global integrated assessment model. The projections show that Europe can significantly increase imports from 1.5 EJ year−1 in 2020 to 8.1 EJ year−1 by 2050 whilst remaining compliant with Renewables Energy Directive recast II (RED II) greenhouse gas (GHG) criteria. Under these conditions, bioenergy could provide annual GHG mitigation of 0.44 GtCO2eq. in 2050. However, achieving this would require a structural diversification of trading partners from the present. Furthermore, socioeconomic and logistical concerns may limit the feasibility of some of the projected major sourcing regions, including Africa and South America. Failure to overcome these challenges within supplying regions could limit European imports by 60%, reducing annual mitigation to 0.16 GtCO2eq. in 2050. From a global perspective, regions with a comparatively carbon‐intense energy system offer an alternative destination for globally traded biomass that could increase the mitigative potential of bioenergy. © 2022 The Authors.

AbstractIn this study, an organic nonlinear optical salt crystal, 4‐(4‐methoxystyryl)‐1‐methylpyridinium 4‐bromobenzenesulfonate (MOS‐BBS), is newly reported. MOS‐BBS crystals exhibit perfectly parallel molecular ordering of 4‐(4‐methoxystyryl)‐1‐methylpyridinium (MOS) cationic chromophores with noncentrosymmetric P1 space group symmetry, which provides an optimal configuration for maximizing the macroscopic second‐order optical nonlinearity. The macroscopic optical nonlinearity of the MOS‐BBS crystals is very large, with the diagonal effective first hyperpolarizability of 160 × 10−30 esu. Furthermore, the MOS‐BBS crystals exhibit a high thermal crystal‐phase stability. The lowest phase transition temperature of the MOS‐BBS crystals is 265°C, which is ~90°C higher than that of previously reported MOS‐based crystals.

Published: August 2022

AbstractThis article reports a session from the virtual international 2021 IUBMB/ASBMB workshop, “Teaching Science on Big Data.” The awareness of using publicly available research data sets for undergraduate training is low in certain parts of the world. Final year projects always revolve around wet‐lab based projects. The challenges occur during COVID‐19 pandemic when it forces full lockdown to the nation, but at the same time faculty members need to provide consistent training to the students and projects to work with. We aim to identify supervisors in the faculty that are ready to convert their proposed project from wet‐lab to an online‐based project. As coordinators of the course we created an online survey to identify projects that can be converted into dry‐lab/online projects. Our surveys identified only 32.5% projects implemented dry‐lab/online based projects. Most academicians described that they are not ready or familiar to apply changes for their research design. With the unknown future of the world living with COVID‐19 and directional changes of life science research toward big data driven research indeed we should be ready to adopt such changes. Awareness on reusing public data sets as tools for research should be provided to strengthen undergraduate training. Life science undergraduates should be exposed to reusing public data sets as these materials are readily available case studies that allow in depth exploration to answer specific research questions. Members of the faculty should take part to pave the way for them, ensuring that they understand that life science research revolves around a multidisciplinary field.
