The Challenge of Water Competition in Physical Adsorption of CO2 by Porous Solids for Carbon Capture Applications – A Short Perspective
Authors: Rajendran Arvind , Shimizu George K. H. , Woo Tom K. 
Published: July 2023

AbstractWith ever‐increasing efforts to design sorbent materials to capture carbon dioxide from flue gas and air, this perspective article is provided based on nearly a decade of collaboration across science, engineering, and industry partners. A key point learned is that a holistic view of the carbon capture problem is critical. While researchers can be inclined to value their own fields and associated metrics, often, key parameters are those that enable synergy between materials and processes. While the role of water in the chemisorption of CO2 is well‐studied, in this perspective, it is hoped to highlight the often‐overlooked but critical role of water in assessing the potential of a physical adsorbent for CO2 capture. This is a challenge that requires interdisciplinarity. As such, this document is written for a general audience rather than experts in any specific discipline.

AbstractThe development of flexible lithium‐ion batteries (LIBs) imposes demands on energy density and high mechanical durability simultaneously. Due to the limited deformability of electrodes, as well as the flat and smooth surface of the metal current collectors, stable/durable/reliable contact between electrode materials and the current collectors remains a challenge, in particular, for electrodes with high loading mass and heavily deformed batteries. Binders play an essential role in binding particles of electrode materials and adhering them to current collectors. Herein, inspired by spider silk, a binder for flexible LIBs is developed, which equips a cross‐linked supramolecular poly(urethane‐urea) to the polyacrylic acid. The binder imparts super high elastic restorability originating from the meticulously engineered hydrogen‐bonding segments as well as extraordinary adhesion. The developed binder provides excellent flexibility and intact electrode morphologies without disintegration even when the electrode is largely deformed, enabling a stable cycling and voltage output even when the batteries are put under tough dynamic deformation tests. The flexible LIBs exhibit a high energy density of 420 Wh L−1, which is remarkably higher than reported numbers. The unique binder design is greatly promising and offers a valuable material solution for LIBs with high‐loading mass and flexible designs.

AbstractFe‐based battery‐type anode materials with many faradaic reaction sites have higher capacities than carbon‐based double‐layer‐type materials and can be used to develop aqueous supercapacitors with high energy density. However, as an insurmountable bottleneck, the severe capacity fading and poor cyclability derived from the inactive transition hinder their commercial application in asymmetric supercapacitors (ASCs). In this work, driven by the “oxygen pumping” mechanism, oxygen‐vacancy‐rich Fe@Fe3O4(v)@Fe3C@C nanoparticles that consist of a unique “fruit with stone”‐like structure are developed, and they exhibit enhanced specific capacity and fast charge/discharge capability. Experimental and theoretical results demonstrate that the capacity attenuation in conventional iron‐based anodes is greatly alleviated in the the Fe@Fe3O4(v)@Fe3C@C anode because the irreversible phase transition to the inactive γ‐Fe2O3 phase can be inhibited by a robust barrier formed by the coupling of oxygen vacancies and Fe─C bonds, which promotes cycle stability (93.5% capacity retention after 24 000 cycles). An ASC fabricated using this Fe‐based anode is also observed to have extraordinary durability, achieving capacity retention of 96.4% after 38 000 cycles, and a high energy density of 127.6 W h kg−1 at a power density of 981 W kg−1.

Published: July 2023

AbstractGas nanobubbles are directly linked to many important chemical reactions. While they can be detrimental to operational devices, they also reflect the local activity at the nanoscale. Here, supercrystals made of highly monodisperse Ag@Pt core–shell nanoparticles are first grown onto a solid support and fully characterized by electron microscopies and X‐ray scattering. Supercrystals are then used as a plasmonic photocatalytic platform for triggering the hydrogen evolution reaction. The catalytic activity is measured operando at the single supercrystal level by high‐resolution optical microscopy, which allows gas nanobubble nucleation to be probed at the early stage with high temporal resolution and the amount of gas molecules trapped inside them to be quantified. Finally, a correlative microscopy approach and high‐resolution electron energy loss spectroscopy help to decipher the mechanisms at the origin of the local degradation of the supercrystals during catalysis, namely nanoscale erosion and corrosion.

AbstractN2 electroreduction reaction (NRR) enables an eco‐friendly NH3 synthesis under mild conditions, which is regarded as a carbon‐neutral alternative technology to the traditional Haber–Bosch process. However, its practical applications are seriously impeded by the difficulty in N2 adsorption and activation over catalysts, as well as the competing hydrogen evolution reaction (HER). In this work, a novel bismuth molybdate nanocatalyst with sufficient oxygen vacancies and high Biconcentration (41.9 at%), BiMoO‐OVs, is synthesized and demonstrated as an excellent NRR electrocatalyst. Benefiting from synergistic effect of the adequate Bi active centers with inert HER activity provided by the high concentration of Bi, and the reinforced N2 adsorption and activation ability of oxygen vacancies, the as‐synthesized BiMoO‐OVs presents a high Faradaic efficiency of 16.38% with a NH3 yield rate of 3.65 µg h−1 cm−2 at −0.4 V (vs RHE) in neutral electrolyte, which outperforms those of most Bi‐based NRR nanocatalysts. Noticeably, it also presents excellent electrochemical durability for at least 24 h. The present work provides a simple and effective strategy for designing low‐cost and high‐performance Bi‐based catalysts.

AbstractPre‐eclampsia is a major cause of maternal and fetal mortality. Low molecular weight heparin sodium (LMWH) reduced the incidence of pre‐eclampsia, may be an effective treatment of pre‐eclampsia. But the underlying mechanism of LMWH is unknown. To improve the molecular utilization rate, chitosan‐LMWH nanoparticles (CHsN) are purchased for the study. The prague of pregnancy Sprague‐Dawley rats are injected with nitroso l‐arginine methyl ester to construct a pre‐eclampsia model. Trichotrophoblast cells HTR‐8/SVneo are cultured under Hypoxia/reoxygenation injury (H/R) simulation conditions to construct the cell model. CHsN ameliorates the integrity of fetal membrane tissue. Administration of CHsN results in decreased urine protein and HB‐EGF levels, accompanied by increased numbers of pups and placenta. Treatment with CHsN increases the proportion of Treg cells and decreases the proportion of Th17 cells. After treatment with CHsN, the levels of LPS, TNF‐α, rank1, slp1, Foxo, NF‐κB, and HIF‐1α are down‐regulated, while the levels of IL‐2, Foxp3, and TGFβ1 are up‐regulated. CRM197 reverses the effect of CHsN. The CHsN improves H/R‐induced HTR‐8/SVneo cells apoptosis through HB‐EGF and affected CD4+T cell differentiation. CHsN ameliorates pre‐eclampsia by regulating Treg/Th17 immune balance and inflammation at the maternal‐fetal interface through HB‐EGF. This provides a theoretical reference for relieving pre‐eclampsia by CHsN.

AbstractSperm‐induced Ca2+ rise is critical for driving oocyte activation and subsequent embryonic development, but little is known about how lasting Ca2+ oscillations are regulated. Here it is shown that NLRP14, a maternal effect factor, is essential for keeping Ca2+ oscillations and early embryonic development. Few embryos lacking maternal NLRP14 can develop beyond the 2‐cell stage. The impaired developmental potential of Nlrp14‐deficient oocytes is mainly caused by disrupted cytoplasmic function and calcium homeostasis due to altered mitochondrial distribution, morphology, and activity since the calcium oscillations and development of Nlrp14‐deficient oocytes can be rescued by substitution of whole cytoplasm by spindle transfer. Proteomics analysis reveal that cytoplasmic UHRF1 (ubiquitin‐like, containing PHD and RING finger domains 1) is significantly decreased in Nlrp14‐deficient oocytes, and Uhrf1‐deficient oocytes also show disrupted calcium homeostasis and developmental arrest. Strikingly, it is found that the mitochondrial Na+/Ca2+ exchanger (NCLX) encoded by Slc8b1 is significantly decreased in the Nlrp14mNull oocyte. Mechanistically, NLRP14 interacts with the NCLX intrinsically disordered regions (IDRs) domain and maintain its stability by regulating the K27‐linked ubiquitination. Thus, the study reveals NLRP14 as a crucial player in calcium homeostasis that is important for early embryonic development.
Electron‐deficient covalent organic frameworks anchored on melamine sponges for visible‐light‐driven H2O2 evolution

Published: July 2023

AbstractA series of covalent organic frameworks (COFs) with β‐ketoenamine linkages named TpTt‐COF, TAPT‐COF, and TpPa‐1 were constructed for photocatalytic H2O2 generation in pure water and ambient air under visible light. Among them, TpTt‐COF performed striking H2O2 yield of 2647 μmol L−1, which is 3.5, 17.5, and 176.5‐fold those of TAPT‐COF, TpPa‐1, and bulk g‐C3N4, respectively, attributing to the electron‐deficient trait, short charge diffusion distance, and the narrowest bandgap of TpTt‐COF. Additionally, to achieve the facile recovery, TpTt‐COF was firmly and evenly anchored on melamine sponges (MS) because plenty of amino groups on the surface of MS could be involved in the β‐ketoenamine formation and guide the synthesis of TpTt‐COF on MS. The corresponding H2O2 evolution over this photocatalyst monolith is also respectable and can be well repeated at least four times. This work is quite instructive for photocatalyst construction based on covalent organic frameworks and facile photocatalytic applications.
Current practice of placental cord insertion documentation in Australia – A sonographer survey
Authors: Ward Samantha , Sun Zhonghua , Maresse Sharon 
Published: July 2023

AbstractIntroductionDuring pregnancy, the umbilical cord attaches to the placenta in a central, eccentric, marginal or velamentous location. Maternal and fetal complications are associated with marginal and velamentous cord insertions, the most clinically significant being perinatal mortality due to undiagnosed vasa praevia. Current literature describes a wide variation regarding regulation of placental cord insertion (PCI) documentation during antenatal ultrasound examinations. This prospective cross‐sectional study aimed to assess the current practice of antenatal PCI documentation in Australia.MethodsMembers of the Australian Sonographer Accreditation Registry were invited to participate in an online survey which was distributed between February and March 2022.ResultsFour hundred ninety sonographers met the inclusion criteria for the study of which 330 (67.3%) have more than 10 years' experience as a sonographer and 375 (76.5%) are employed primarily in a public or private setting offering general ultrasound. Most respondents (89.6%) indicated documentation of the PCI site is departmental protocol at the second trimester anatomy scan (17–22 weeks gestation), but PCI documentation is protocol in less than 50% of other obstetric ultrasound examinations listed in the survey. The PCI site is included in the formal ultrasound report at a rate significantly less than inclusion in the departmental protocol and the sonographer's worksheet.ConclusionsConsidering the potential maternal and fetal complications associated with abnormal PCI and the ease at which the PCI site is identified in the first and second trimesters, we believe that standard inclusion of the PCI site in departmental protocol and in the formal ultrasound report from 11 weeks gestation, regardless of whether it is normal or abnormal, would prove invaluable.

AbstractINTRODUCTIONChronic cerebral hypoperfusion is one of the assumed pathophysiological mechanisms underlying vascular cognitive impairment (VCI). We investigated the association between baseline cerebral blood flow (CBF) and cognitive decline after 2 years in patients with VCI and reference participants.METHODSOne hundred eighty‐one participants (mean age 66.3 ± 7.4 years, 43.6% women) underwent arterial spin labeling (ASL) magnetic resonance imaging (MRI) and neuropsychological assessment at baseline and at 2‐year follow‐up. We determined the association between baseline global and lobar CBF and cognitive decline with multivariable regression analysis.RESULTSLower global CBF at baseline was associated with more global cognitive decline in VCI and reference participants. This association was most profound in the domain of attention/psychomotor speed. Lower temporal and frontal CBF at baseline were associated with more cognitive decline in memory.DISCUSSIONOur study supports the role of hypoperfusion in the pathophysiological and clinical progression of VCI.Highlights
Impaired cerebral blood flow (CBF) at baseline is associated with faster cognitive decline in VCI and normal aging.
Our results suggest that low CBF precedes and contributes to the development of vascular cognitive impairment.
CBF determined by ASL might be used as a biomarker to monitor disease progression or treatment responses in VCI.

ObjectiveInvestigations of cerebrospinal fluid (CSF) flow aberrations in Huntington's disease (HD) are of growing interest, as impaired CSF flow may contribute to mutant Huntington retention and observed heterogeneous responsiveness to intrathecally administered therapies.MethodWe assessed net cerebral aqueduct CSF flow and velocity in 29 HD participants (17 premanifest and 12 manifest) and 51 age‐ and sex matched non‐HD control participants using 3‐Tesla magnetic resonance imaging methods. Regression models were applied to test hypotheses regarding: (i) net CSF flow and cohort, (ii) net CSF flow and disease severity (CAP‐score), and (iii) CSF volume after correcting for age and sex.ResultsGroup‐wise analyses support a decrease in net CSF flow in HD (mean 0.14 ± 0.27 mL/min) relative to control (mean 0.32 ± 0.20 mL/min) participants (p = 0.02), with lowest flow in the manifest HD cohort (mean 0.04 ± 0.25 mL/min). This finding was explained by hyperdynamic CSF movement, manifesting as higher caudal systolic CSF flow velocity and higher diastolic cranial CSF flow velocity across the cardiac cycle, in HD (caudal flow: 0.17 ± 0.07 mL/s, cranial flow: 0.14 ± 0.08 mL/s) compared to control (caudal flow: 0.13 ± 0.06 mL/s, cranial flow: 0.11 ± 0.04 mL/s) participants. A positive correlation between cranial diastolic flow and disease severity was observed (p = 0.02).InterpretationsFindings support aqueductal CSF flow dynamics changing with disease severity in HD. These accelerated changes are consistent with changes observed over the typical adult lifespan, and may have relevance to mutant Huntington retention and intrathecally administered therapeutics responsiveness.

Liquids with Permanent Macroporosity
Authors: Egleston Benjamin D. , Greenaway Rebecca L. 
Published: July 2023

AbstractPermanent macropores (>50 nm) had not been reported in the liquid state until a recent report by Tao Li and co‐workers describing a synthetic strategy to form a porous liquid with dual micro‐macroporosity. This is prepared by producing hierarchically porous particles that are surface coated and fluidised by dispersion. Surface micropores enable permanent porosity by steric exclusion of the fluid phase. The material has a considerable water uptake capacity (27 % w/w) due to large (480 nm) unoccupied macropores. This also enables switching of thermal conductivity on uptake of water. These are new properties translated from porous solids to the liquid state.

AbstractMagnetic monolayers show great promise for future applications in nanoelectronics, data storage, and sensing. The research in magnetic two‐dimensional (2D) materials focuses on synthetic iodides and tellurides, which suffer from a lack of ambient stability. So far, naturally occurring layered magnetic materials have been overlooked. These minerals offer a unique opportunity to explore complex air‐stable layered systems with high concentration of magnetic ions. Magnetic ordering in iron‐rich phyllosilicates is demonstrated, focusing on minnesotaite, annite, and biotite. These naturally occurring layered materials integrate local moment baring ions of iron via magnesium/aluminum substitution in their octahedral sites. Self‐inherent capping by silicate/aluminate tetrahedral groups enables air stability of ultra‐thin layers. Their structure and iron oxidation states are determined via Raman and X‐ray spectroscopies. Superconducting quantum interference device magnetometry measurements are performed to examine the magnetic ordering. Paramagnetic or superparamagnetic characteristics at room temperature are observed. Below 40 K ferrimagnetic or antiferromagnetic ordering occurs. In‐field magnetic force microscopy on exfoliated flakes confirms that the paramagnetic response at room temperature persists down to monolayers. Further, a correlation between the mixture of the oxidation states of iron and the critical ordering temperature is established, indicating a path to design materials with higher critical temperatures via oxidation state engineering.

AbstractLithium‐ion capacitors (LICs) represent promising high‐power energy storage devices, most commonly composed of a lithium‐ion intercalation anode (e. g., graphite or hard carbon), a supercapacitor activated carbon (AC) cathode, and an electrolyte with 1 M LiPF6 in carbonate solvents. LiPF6 is susceptible to hydrolysis, forming HF, which leads to challenges for disassembly and recycling, risks during hazardous events, and extensive energy consumption during production. Here, we report on the feasibility of replacing LiPF6 with the non‐hydrolysing salt LiFSI for use with AC electrodes. Based on voltage hold measurements in a half‐cell setup, good long‐term stability is achieved with an upper cut‐off voltage of 3.95 V vs. Li/Li+, potentially enabling cell voltages of ~3.8 V when combined with graphite or silicon‐based anodes (operating at ~0.1 V vs. Li/Li+) in LIC full cells. The lower cut‐off voltage was determined to be 2.15 V vs. Li/Li+. The systematic comparison of CV, leakage current analysis and capacity retention upon voltage hold highlights the importance of the latter method to provide a realistic assessment of the electrochemical stability window (ESW) of LiFSI on a commercial AC electrode. The morphological and surface‐chemical post‐mortem analysis of AC electrodes used with LiFSI revealed that the oxidation of the FSI anion, as evidenced by the presence of new S 2p and N 1s features in the XPS spectra, and an increasing number of oxygenated species on the AC were the main processes causing capacity fade at positive polarization.
