BackgroundInfant development is adversely affected in the context of postnatal depression. This relationship may be mediated by both the nature of early mother-infant interactions and the quality of the home environment.AimsTo establish the usefulness of the Global Ratings Scales of Mother–Infant Interaction and the Infant–Toddler version of the Home Observation for the Measurement of the Environment (IT–HOME), and to test expected associations of the measures with characteristics of the social context and with major or minor depression.MethodBoth assessments were administered postnatally in four European centres; 144 mothers were assessed with the Global Ratings Scales and 114 with the IT–HOME. Affective disorder was assessed by means of the Structured Clinical Interview for DSM–IV Disorders.ResultsAnalyses of mother–infant interaction indicated no main effect for depression but maternal sensitivity to infant behaviour was associated with better infant communication, especially for women who were not depressed. Poor overall emotional support also reduced sensitivity scores. Poor support was also related to poorer IT–HOME scores, but there was no effect of depression.ConclusionsThe Global Ratings Scales were effectively applied but there was less evidence of the usefulness of the IT–HOME.

BackgroundLittle is known about the availability and uptake of health and welfare services by women with postnatal depression in different countries.AimsWithin the context of a cross cultural research study, to develop and test methods for undertaking quantitative health services research in postnatal depression.MethodInterviews with service planners and the collation of key health indicators were used to obtain a profile of service avail ability and provision. A service use questionnaire was developed and administered to a pilot sample in a number of European study centres.ResultsMarked differences in service access and use were observed between the centres, including postnatal nursing care and contacts with primary care services. Rates of use of specialist services were generally low. Common barriers to access to care included perceived service quality and responsiveness. On the basis of the pilot work, a postnatal depression version of the Service Receipt Inventory was revised and finalised.ConclusionsThis preliminary study demonstrated the methodological feasibility of describing and quantifying service use, highlighted the varied and often limited use of care in this population, and indicated the need for an improved understanding of the resource needs and implications of postnatal depression.

Published: January 2024

Abstract2D materials, with outstanding optical, thermal, and electric properties, are emerging as promising candidates for fabricating high‐performance photodetectors. Recently, impressive progresses have been made in this area and some challenges are remaining to improve the properties of photodetectors. As one important part in the mainstream photodetection mechanisms, photothermoelectric (PTE) effect is showing unique priorities in fabricating advanced photodetectors, especially broadband detection operating in the mid‐infrared and terahertz spectral regime. Here, recent progress on PTE photodetectors based on layered 2D materials is reviewed. The physical mechanism of PTE effect is first discussed and then the optical and thermoelectric properties of various 2D materials are analyzed. Furthermore, strategies to improve the photodetection performance of PTE detectors are summarized in two major categories including enhanced photothermal conversion and thermoelectric conversion processes. Finally, the challenges and prospects for future research in 2D thermoelectric materials and PTE detectors are also provided.

AbstractNatural blood vessels have completed functions, including elasticity, compliance, and excellent antithrombotic properties because of their mature structure. To replace damaged blood vessels, vascular grafts should perform these functions by simulating the natural vascular structures. Although the structures of natural blood vessels are thoroughly explored, constructing a small‐diameter vascular graft that matches the mechanical and biological properties of natural blood vessels remains a challenge. A hierarchical vascular graft is fabricated by Electrospinning, Braiding, and Thermally induced phase separation (EBT) processes, which could simulate the structure of natural blood vessels. The internal electrospun structure facilitates the adhesion of endothelial cells, thereby accelerating endothelialization. The intermediate PLGA fabric exhibits excellent mechanical properties, which allow it to maintain its shape during long‐term transplantation and prevent graft expansion. The external macroporous structure is beneficial for cell growth and infiltration. Blood vessel remodeling aims to combine a structure that promotes tissue regeneration with anti‐inflammatory materials. The results in vitro demonstrated that it EBT vascular graft (EBTVG) has matched the mechanical properties, reliable cytocompatibility, and the strongest endothelialization in situ. The results in vitro and replacement of the resected artery in vivo suggest that the EBTVG combines different structural advantages with biomechanical properties and reliable biocompatibility, significantly promoting the stabilization and regeneration of vascular endothelial cells and vascular smooth muscle cells, as well as stabilizing the blood microenvironment.

AbstractPulmonary air leak is the most common complication of lung surgery, contributing to post‐operative morbidity in up to 60% of patients; yet, there is no reliable treatment. Available surgical sealants do not match the demanding deformation mechanics of lung tissue; and therefore, fail to seal air leak. To address this therapeutic gap, a sealant with structural and mechanical similarity to subpleural lung is designed, developed, and systematically evaluated. This “lung‐mimetic” sealant is a hydrofoam material that has alveolar‐like porous ultrastructure, lung‐like viscoelastic properties (adhesive, compressive, tensile), and lung extracellular matrix‐derived signals (matrikines) to support tissue repair. In biocompatibility testing, the lung‐mimetic sealant shows minimal cytotoxicity and immunogenicity in vitro. Human primary monocytes exposed to sealant matrikines in vitro upregulate key genes (MARCO, PDGFB, VEGF) known to correlate with pleural wound healing and tissue repair in vivo. In rat and swine models of pulmonary air leak, this lung‐mimetic sealant rapidly seals air leak and restores baseline lung mechanics. Altogether, these data indicate that the lung‐mimetic sealant can effectively seal pulmonary air leak and promote a favorable cellular response in vitro.

AbstractIron oxide nanoprobes exhibit substantial potential in magnetic resonance imaging (MRI) of kidney diseases and can eliminate the nephrotoxicity of gadolinium‐based contrast agents (GBCAs). Nevertheless, there is an extreme shortage of highly sensitive and renal clearable iron oxide nanoprobes suitable for early kidney damage detection through MRI. Herein, a renal clearable ultra‐small ferrite nanoprobe (UMFNPs@ZDS) is proposed for highly sensitive early diagnosis of kidney damage via structural and functional MRI in vivo for the first time. The nanoprobe comprises a ferrite core coated with a zwitterionic layer, and possesses a high T1 relaxivity (12.52 mm−1s−1), a small hydrodynamic size (6.43 nm), remarkable water solubility, excellent biocompatibility, and impressive renal clearable ability. In a rat model of unilateral ureteral obstruction (UUO), the nanoprobe‐based MRI can not only accurately visualize the locations of renal injury, but also provide comprehensive functional data including peak value, peak time, relative renal function (RRF), and clearance percentage via MRI. The findings prove the immense potential of ferrite nanoprobes as a superior alternative to GBCAs for the early diagnosis of kidney damage.

AbstractBandstructure engineering using alloying is widely utilized for achieving optimized performance in modern semiconductor devices. While alloying has been studied in monolayer transition metal dichalcogenides, its application in van der Waals heterostructures built from atomically thin layers is largely unexplored. Here, heterobilayers made from monolayers of WSe2 (or MoSe2) and MoxW1 − xSe2 alloy are fabricated and nontrivial tuning of the resultant bandstructure is observed as a function of concentration x. This evolution is monitored by measuring the energy of photoluminescence (PL) of the interlayer exciton (IX) composed of an electron and hole residing in different monolayers. In MoxW1 − xSe2/WSe2, a strong IX energy shift of ≈100 meV is observed for x varied from 1 to 0.6. However, for x < 0.6 this shift saturates and the IX PL energy asymptotically approaches that of the indirect bandgap in bilayer WSe2. This observation is theoretically interpreted as the strong variation of the conduction band K valley for x > 0.6, with IX PL arising from the K − K transition, while for x < 0.6, the bandstructure hybridization becomes prevalent leading to the dominating momentum‐indirect K − Q transition. This bandstructure hybridization is accompanied with strong modification of IX PL dynamics and nonlinear exciton properties. This work provides foundation for bandstructure engineering in van der Waals heterostructures highlighting the importance of hybridization effects and opening a way to devices with accurately tailored electronic properties.
Configurational Disorder, Strong Anharmonicity, and Coupled Host Dynamics Lead to Superionic Transport in Li3YCl6 (LYC)

Published: January 2024

AbstractIn superionic crystals, liquid‐like ionic diffusivities often come hand‐in‐hand with ultra‐low thermal conductivity and soft vibrational dynamics. However, generalized relationships between ion transport and vibrational dynamics remain elusive due to the diversity of superionic materials and complex underlying mechanisms. Here, the links between vibrational dynamics and ion transport in close‐packed lithium halide ion conductor Li3YCl6 (LYC) are examined using a suite of atomistic first‐principles methods. It is shown that configurational disorder, lattice anharmonicity, and coupled host‐mobile ion vibrational dynamics together induce a transition to the superionic state. Statistical correlations between ionic hops and activation of the distribution of vibrational modes are found. However, typical phenomena associated with superionic conductors such as selective breakdown of zone‐boundary soft phonons, or long wavelength transverse acoustic modes as in the ‘phonon‐liquid‐electron crystal’ concept, are not present. Instead, anharmonic zone‐boundary modes aiding Li diffusion are found to broaden and soften selectively but persist across the superionic transition. These anharmonic modes couple Li ion motion with the vibrations of the flexible close‐packed anion framework, which remains stable and facilitates ionic hopping. The results provide insights into how configurational disorder and soft‐yet‐resilient vibrational modes enable ionic hopping, particularly in 3D close‐packed crystals.

AbstractZinc pnictides, particularly Zn3As2, hold significant promise for optoelectronic applications owing to their intrinsic p‐type behavior and appropriate bandgaps. However, despite the outstanding properties of colloidal Zn3As2 nanocrystals, research in this area is lacking because of the absence of suitable precursors, occurrence of surface oxidation, and intricacy of the crystal structures. In this study, a novel and facile solution‐based synthetic approach is presented for obtaining highly crystalline p‐type Zn3As2 nanocrystals with accurate stoichiometry. By carefully controlling the feed ratio and reaction temperature, colloidal Zn3As2 nanocrystals are successfully obtained. Moreover, the mechanism underlying the conversion of As precursors in the initial phases of Zn3As2 synthesis is elucidated. Furthermore, these nanocrystals are employed as active layers in field‐effect transistors that exhibit inherent p‐type characteristics with native surface ligands. To enhance the charge transport properties, a dual passivation strategy is introduced via phase‐transfer ligand exchange, leading to enhanced hole mobilities as high as 0.089 cm2 V−1 s−1. This study not only contributes to the advancement of nanocrystal synthesis, but also opens up new possibilities for previously underexplored p‐type nanocrystal research.

AbstractSkeletal metastasis is common in patients with advanced breast cancer and often caused by immune evasion of disseminated tumor cells (DTCs). In the skeleton, tumor cells not only disseminate to the bone marrow but also to osteogenic niches in which they interact with newly mineralizing bone extracellular matrix (ECM). However, it remains unclear how mineralization of collagen type I, the primary component of bone ECM, regulates tumor‐immune cell interactions. Here, a combination of synthetic bone matrix models with controlled mineral content, nanoscale optical imaging, and flow cytometry are utilized to evaluate how collagen type I mineralization affects the biochemical and biophysical properties of the tumor cell glycocalyx, a dense layer of glycosylated proteins and lipids decorating their cell surface. These results suggest that collagen mineralization upregulates mucin‐type O‐glycosylation and sialylation by tumor cells, which increases their glycocalyx thickness while enhancing resistance to attack by natural killer (NK) cells. These changes are functionally linked as treatment with a sialylation inhibitor decreased mineralization‐dependent glycocalyx thickness and made tumor cells more susceptible to NK cell attack. Together, these results suggest that interference with glycocalyx sialylation may represent a therapeutic strategy to enhance cancer immunotherapies targeting bone‐metastatic breast cancer.

AbstractAlthough sensitizing traditional fluorescent dyes with thermally activated delayed fluorescence (TADF) exciplexes has been extensively studied, the device performance of solution‐processed organic light‐emitting diodes (OLEDs) still lags far behind in this regard. Herein, the novel exciplex with high up‐conversion efficiency composed of a triazatruxene‐based donor and a triazine‐based acceptor is employed as a TADF sensitizer to fluorescent dye in solution‐processed hyperfluorescent OLEDs. Benefiting from the small activation energy for triplet up‐conversion and less non‐radiative recombination of triplet excitons, the new TADF exciplex can up‐convert efficiently non‐radiative triplet excitons through reverse intersystem crossing. Besides, expeditious up‐conversion processes also shorten the residence time of triplet excitons, giving rise to significant suppression of detrimental Dexter energy transfer from the exciplex sensitizer to the dopant. By maximizing the triplet up‐conversion efficiency of exciplex sensitizers, the optimized OLEDs achieve a maximum external quantum efficiency (EQEmax) of 16.0%, which is the first report for the solution‐processed exciplex‐sensitized hyperfluorescent OLEDs with EQEmax exceeding 15%. These results validate that the up‐conversion efficiency of triplet excitons in the exciplexes strongly affects the performance of exciplex‐sensitized fluorescent devices, and the triazatruxene‐based molecules are promising donor candidates for constructing the exciplexes with high up‐conversion efficiency.

AbstractInvestigating the reversible structural transformation of stimuli‐responsive metal–organic frameworks (MOFs) through single‐crystal diffraction and establishing a structure–property relationship pose a significant challenge. Herein, the controllable synthesis of Co‐MOF‐1 and Co‐MOF‐2 by incorporating water into the solvothermal synthesis process is presented. In comparison to the trinuclear [Co3(COO)8]2− clusters found in Co‐MOF‐1, Co‐MOF‐2 presents a variable dinuclear [Co2(COO)4(H2O)5] cluster. Single crystal diffraction studies, utilizing synchrotron radiation, confirm the reversible two‐step transformation. The presence of various organic solvents induces the single‐crystal‐to‐single‐crystal (SC‐to‐SC) transformation of Co‐MOF‐2. This transformation is initiated by the cleavage of three coordinated water molecules and subsequent coordination of carboxylates in the ligand, resulting in solvatochromic behavior. Further, the reversible stimuli‐responsive behavior can also be rapidly induced under the stimuli of heat, vacuum, and X‐rays. This study successfully demonstrates the crystallographic and spectroscopic snapshots of dynamic coordination bonds in MOFs and contributes to a deeper understanding of the structure–property relationship.

AbstractCr3+‐activated near‐infrared (NIR) phosphors have gained extensive attention for use in NIR phosphor‐converted light‐emitting diodes (pc‐LEDs), which are required for smart NIR spectroscopy techniques. Nevertheless, obtaining broadband NIR‐emitting phosphors with outstanding thermal stabilities and photoluminescence (PL) efficiencies remains a significant challenge. Herein, considering NaSr2XGe5O14 (X = Al, Ga, Sc, and In) as hosts, which possess a large band gap and multiple sites for the substitution of Cr3+ ions. NaSr2XGe5O14:Cr3+ phosphors are successfully prepared using a solid‐state reaction technology. Upon blue light excitation, the phosphors cover a broad NIR emission band in 650–1100 nm region. Notably, an abnormal blueshift and PL enhancement are observed following the substitution of Al/Ga with Sc/In. In particular, the PL internal quantum efficiency is improved from 34.5% (NaSr2GaGe5O14: Cr3+) to 87.5% (NaSr2ScGe5O14: Cr3+). Moreover, the manufactured NIR pc‐LED exhibited an exceptional photoelectric efficiency of 17.7% with an NIR output power of 10.2 mW at 20 mA, and its potential application in nondestructive detection is demonstrated.

AbstractColor‐tunable luminescent polymers are highly desirable materials for meeting the daily needs of humans in terms of circadian rhythm, yet they are rarely reported. Herein, a feasible approach is developed for color‐tunable thermally activated delayed fluorescence (TADF) conjugated polymers by incorporating green and red TADF units into blue fluorescent polymeric backbone. The solution‐processed OLEDs based on the synthesized polymers exhibit high‐efficiency red emission with a maximum external quantum efficiency (EQEmax) of 26.1% under low voltage (6 V). With a slight increase in voltage, warm white emission with EQEmax of 23.9%, color rendering index (CRI) of 76 and low corelated color temperature (CCT) of 1700 K is obtained. These results represent the highest efficiencies among the red and warm white OLEDs based on TADF polymers, respectively. Intriguingly, under higher voltage (10 V), warm white emission with high CRI of 87, CCT of 3216 K, and luminance of over 5300 cd m−2 is accessible. This work provides a promising approach for intelligent lighting by voltage‐regulating white OLEDs.
