Published: December 2023

AbstractIn this study, eutectic gallium–indium alloy (EGaIn) liquid metal is used as the rear electrode for perovskite solar cells (PSCs), where the interfacial properties of the device, particularly the beneficial roles of the surface oxide of the liquid metal, are explored. The findings demonstrate that the native oxide of the EGaIn electrode significantly affects the stability of photovoltaic performance and impedance characteristics including series and shunt resistances. Based on the results, the following hypothesis is formulated: the oxide interlayer serves two crucial functions of a barrier against metal diffusion and a tunnel for enhancing charge extraction and transfer. The results of elemental mapping and trap density calculation support the former function of the hypothesis that the oxide film can effectively prevent metal penetration into the perovskite layer. Furthermore, measurements involving capacitance−voltage and time‐resolved photoluminescence confirm that the oxide film on the liquid metal eliminates the interfacial Schottky barrier, promoting efficient charge extraction and transfer processes. Finally, the investigation is extended to develop flexible PSCs using the EGaIn electrode, which consistently exhibits stable performance during repeated bending cycles. Notably, the EGaIn rear electrode can be readily removed and collected through a straightforward acid treatment, offering a promising avenue for efficient cell recycling.

AbstractPlatinum selenide (PtSe2), an emerging 2D material, has attracted extensive attention owing to its wide‐tunable bandgap and ultrahigh conductivity for potential applications in optoelectronic and energy devices. However, the preparation of atomically thin PtSe2 remains a big challenge due to its large formation energy. Herein, the robust synthesis of large‐area ultrathin PtSe2 microbelts via a step‐induced separation growth strategy on Au(001) substrate is demonstrated. Thanks to the high controllability of this approach, the continuous modulation of the thickness of PtSe2 microbelts from monolayer to bulk is realized and the sample coverage from ≈5% to ≈100% by coordinately tuning the growth temperature and time. Theory calculations indicate that the significant reduction of formation energy of PtSe2 nucleation at the Au steps, along with the high‐efficiency separation‐supply of Pt precursor, are responsible for the robust synthesis of PtSe2. Owing to the rich‐edges with abundant active sites and metallic conduction features of ultrathin PtSe2 microbelt, it can act as an excellent electrocatalyst, featured with a record high hydrogen evolution reaction efficiency (Tafel slope: 37 mV dec−1). This work provides new insights into the highly efficient synthesis of large‐scale 2D materials for exploring their unique physics and fascinating applications.

AbstractA complete photocatalytic degradation of dibutyl phthalate (DBP) using ferroelectric doped‐bismuth ferrite‐ (BiFeO3; BFO) graphene oxide (GO) nanocomposites is achieved. The local ferroelectric properties of doped BFO photocatalysts supported onto GO is well‐utilized for photodegradation of pollutant. A complete photodegradation of DBP under ultraviolet light irradiation is achieved within 2.5 h, traced by gas chromatography. The best photocatalytic activity of Bi0.95Ag0.05Fe0.95Mn0.05O3‐GO (ABMGO) nanocomposite is attributed to its large intrinsic local ferroelectric polarization, which suppresses the recombination of photoinduced charge carriers and the presence of Ag+ and Mn4+ as new active sites on the large surface of ABMGO speeds up the photodegradation of DBP. The possible mechanism of photodegradation of DBP is presented using mass spectrometry includes several intermediate products; phthalic acid, benzoic acid, benzaldehyde, and hydroquinone and 3‐methyl butyric acid which are harmless for the environment compared to DBP.

Published: December 2023

AbstractQuantifying the intrinsic properties of 2D materials is of paramount importance for advancing their applications. Large‐scale production of 2D materials merits the need for approaches that provide direct information about the role of growth substrate on 2D material properties. Transferring the 2D material from its growth substrates can modify the intrinsic properties of the asgrown 2D material. In this study, suspended chemical vapor deposition (CVD) graphene films are prepared directly on their growth substrates in a high‐density grid array. The approach facilitates the quantification of intrinsic strain and doping in suspended CVD graphene films. To achieve this, transmission electron microscopy and large‐area Raman mapping are employed. Remarkably, the analysis reveals consistent patterns of compressive strain (≈−0.2%) both in the diffraction patterns and Raman maps obtained from these suspended graphene films. By conducting investigations directly on the growth substrates, the potential influences introduced during the transfer process are circumvented effectively. Consequently, the methodology offers a robust and reliable means of studying the intrinsic properties of 2D materials in their authentic form, uninfluenced by the transfer‐induced alterations that may skew the interpretation of their properties.

AbstractIon doping is an effective strategy for achieving high‐performance flexible Cu2ZnSn(S,Se)4 (CZTSSe) solar cells by defect regulations. Here, a Li&Na co‐doped strategy is applied to synergistically regulate defects in CZTSSe bulks. The quality absorbers with the uniformly distributed Li and Na elements are obtained using the solution method, where the acetates (LiAc and NaAc) are as additives. The concentration of the harmful CuZn anti‐site defects is decreased by 8.13% after Li incorporation, and that of the benign NaZn defects is increased by 36.91% after Na incorporation. Synergistic Li&Na co‐doping enhances the carrier concentration and reduces the interfacial defects concentration by one order of magnitude. As a result, the flexible CZTSSe solar cell achieves a power conversion efficiency (PCE) of 10.53% with certified 10.12%. Because of the high PCE and the homogeneous property, the Li&Na co‐doped device is fabricated to a large area (2.38 cm2) and obtains 9.41% PCE. The co‐doping investigation to synergistically regulate defects provides a new perspective for efficient flexible CZTSSe solar cells.

Abstract4‐Aryl‐1H‐isochromene derivatives have been successfully synthesized by Brønsted acid‐catalyzed pinacol rearrangement/intramolecular cyclization of the substituted 1‐(2‐(hydroxymethyl)phenyl)‐2‐arylethane‐1,2‐diols. The reaction generally proceeded with low catalyst loading of trifluoromethanesulfonic acid (5 mol%) for short reaction times (10‐20 min) to furnish the desired 4‐aryl‐1H‐isochromenes which were subsequently hydrogenated to 4‐aryl‐isochromans with up to 90 % yield. Moreover, oxidation of the resulting 4‐aryl‐isochroman provided the desired 4‐aryl‐isochroman‐1‐one in good yield.

AbstractNanohybrid photosystems have advantages in converting solar energy into electricity, while natural photosystems based solar‐powered energy‐storage device is still under developed. Here, we fabricate a new kind of photo‐rechargeable zinc‐ion hybrid capacitor (ZHC) benefiting from light‐harvesting carbon dots (CDs) and natural thylakoids for realizing solar energy harvesting and storage simultaneously. Under solar light irradiation, the embedded CDs in thylakoids (CDs/Thy) can convert the less absorbed green light into highly absorbed red light for thylakoids, besides, Förster resonance energy transfer (FRET) between CDs and Thy also occurs, which facilitates the photoelectrons generation during thylakoids photosynthesis, thereby resulting in 6‐fold photocurrent output in CDs/Thy hybrid photosystem, compared to pristine thylakoids. Using CDs/Thy as the photocathode in ZHCs, the photonic hybrid capacitor shows photoelectric conversion and storage features. CDs can improve the photo‐charging voltage response of ZHCs to ≈1.2 V with a remarkable capacitance enhancement of 144 % under solar light. This study provides a promising strategy for designing plant‐based photonic and electric device for solar energy harvesting and storage.

AbstractChromophores with hybridized local and charge‐transfer (HLCT) excited state are promising for the realization of high performance blue organic light‐emitting diodes (OLEDs). The rational manipulation of HLCT excited state for efficient emitters remains challenging. Herein, we present three donor‐π‐acceptor (D‐π‐A) molecules (mPAN, mPANPH, and mPNAPH) with phenanthro[9,10‐d]imidazole (PI) and pyridinyl as donor and π‐bridge respectively. Changes in various kinds of polycyclic aromatic derivative acceptors (anthracene, 9‐phenylanthracene, and 1‐phenylnaphthalene) could manipulate the excited states and optoelectronic properties. Theoretical calculations reveal that the S1 state of mPNAPH exhibits HLCT nature while the other two molecules show local excited (LE) state dominated feature. The photophysical properties also demonstrate this characteristic. Therefore, compared with mPAN and mPANPH, mPNAPH has higher photoluminescence quantum yield (PLQY) whether in solutions or neat films. Ultimately, the non‐doped devices based on these emitters show high luminance larger than 35000 cd m−2, and high maximum external quantum efficiencies (EQEmaxs) larger than 5 % with low efficiency roll‐off. In particular, the mPNAPH‐based device displays an excellent performance of pure blue emission at 456 nm with Commission Internationale de L'Eclairage coordinate of (0.15, 0.16) and EQEmax of 6.13 % that benefited from the HLCT state and high‐lying reverse intersystem crossing process.

AbstractBackgroundEvidence was lacking for the early choice of radiofrequency ablation (RFA) among patients with early‐onset atrial fibrillation (AF).HypothesisThis study aimed to explore whether earlier RFA was associated with better clinical outcomes among early‐onset AF patients.MethodsPatients, who were diagnosed with AF before 45 years and underwent their first RFA procedures at baseline of the China Atrial Fibrillation registry, were enrolled and divided into four diagnosis‐to‐ablation time (DAT) groups: DAT ≤ 1 year, 1 year < DAT ≤ 3 years, 3 years < DAT ≤ 6 years, and DAT > 6 years. Another group of nonablation patients, who were newly diagnosed with AF and younger than 45 years, were also included. Adjusted associations of groups with composite cardiovascular events (cardiovascular death, embolism, major hemorrhages, or cardiac rehospitalization) or recurrent AF were analyzed using Cox proportional hazards models.ResultsAmong 1694 patients who underwent their first RFA at enrollment, incidences of composite cardiovascular outcomes were increasing with extension of DAT (DAT ≤ 1 year: 6.1/100 person‐years, 1 year < DAT ≤ 3 years: 7.9/100 person‐years, 3 years < DAT ≤ 6 years: 7.6/100 person‐years, DAT > 6 years: 10.5/100 person‐years; p < .001). In comparison with DAT > 6 years group, the DAT ≤ 1 year group was associated with reduced risk of cardiovascular events (adjusted hazard ratio, HR [95% confidence interval, CI] = 0.64 [0.47–0.87], p = .005) and AF recurrence (adjusted HR [95% CI] = 0.70 [0.57–0.88], p = .002). Associations remained similar after stratified by AF types. Compared to nonablation group (n = 413), DAT ≤ 1year patients tended to show lower cardiovascular risk (adjusted HR [95% CI] = 0.78 [0.58–1.05], p = .099) and lower risk of recurrent AF (adjusted HR [95% CI] = 0.46 [0.38–0.55], p < .001).ConclusionsA shorter DAT was associated with a lower risk of cardiovascular events and recurrent AF for early‐onset AF patients.

AbstractCarbonyl rich conjugated polymer electrode materials for lithium‐ion batteries possessed the advantages of strong molecular design ability, abundance and high theoretical capacity. In this work, a Co2+ coordinated conjugated polymer using 2,3,5,6‐tetraamino‐p‐benzoquinone (TABQ) as building block was constructed and developed as electrode material for all organic symmetric lithium‐ion batteries, outputting a specific capacity of over 100 mAh g−1 after 50 cycles at 50 mA g−1. Performances of Co‐TABQ in half cells were explored. The Co‐TABQ cathode delivered a capacity of 133.3 mAh g−1 after 150 cycles at 20 mA g−1. When cycled at higher current density of 500 mA g−1, the capacity gradually increased to 109.4 mAh g−1 after 4000 cycles. The Co‐TABQ anode displayed a stable capacity of 568.6 mAh g−1 at 1 A g−1. The charge transfer within the electrode was greatly reduced due to the metallic centers in the extended conjugated skeleton, and the reversible Li+ storage was achieved by the active C=O and imine groups. This work showed the great potential of metal mediated conjugated polymer in Lithium‐ion batteries.

AbstractThe SIMBA (Simultaneous Imaging and Manipulation of genomic loci by Biomolecular Assemblies) system is an innovative CRISPR‐based imaging technique that leverages dCas9‐SunTag and FRB‐mCherry‐HP1α, with scFv‐FKBP acting as a bridge. This powerful system enables simultaneous visualization and manipulation of genomic loci. The dCas9‐SunTag fusion protein allows for precise targeting of specific genomic sites, and the FRB‐mCherry‐HP1α fusion protein facilitates the condensation of chromatin at the targeted loci. The scFv‐FKBP bridge protein links dCas9‐SunTag and FRB‐mCherry‐HP1α, ensuring efficient and specific recruitment of HP1α to the desired genomic loci.

Harnessing atomic force microscopy‐based single‐cell analysis to advance physical oncology
Authors: Li Mi 
Published: December 2023

AbstractSingle‐cell analysis is an emerging and promising frontier in the field of life sciences, which is expected to facilitate the exploration of fundamental laws of physiological and pathological processes. Single‐cell analysis allows experimental access to cell‐to‐cell heterogeneity to reveal the distinctive behaviors of individual cells, offering novel opportunities to dissect the complexity of severe human diseases such as cancers. Among the single‐cell analysis tools, atomic force microscopy (AFM) is a powerful and versatile one which is able to nondestructively image the fine topographies and quantitatively measure multiple mechanical properties of single living cancer cells in their native states under aqueous conditions with unprecedented spatiotemporal resolution. Over the past few decades, AFM has been widely utilized to detect the structural and mechanical behaviors of individual cancer cells during the process of tumor formation, invasion, and metastasis, yielding numerous unique insights into tumor pathogenesis from the biomechanical perspective and contributing much to the field of cancer mechanobiology. Here, the achievements of AFM‐based analysis of single cancer cells to advance physical oncology are comprehensively summarized, and challenges and future perspectives are also discussed.Research Highlights

AbstractCycling hypoxia (cycH) is a prevalent form of tumor hypoxia that is characterized by exposure of tumor cells to recurrent phases of hypoxia and reoxygenation. CycH has been associated with a particularly aggressive cellular phenotype of tumor cells and increased therapy resistance. By performing comparative analyses under normoxia, physoxia, chronic hypoxia, and cycH, we here uncover distinct effects of cycH on the phenotype of human papillomavirus (HPV)‐positive cervical cancer cells. We show that—other than under chronic hypoxia—viral E6/E7 oncogene expression is largely maintained under cycH as is the E6/E7‐dependent regulation of p53 and retinoblastoma protein. Further, cycH enables HPV‐positive cancer cells to evade prosenescent chemotherapy, similar to chronic hypoxia. Moreover, cells under cycH exhibit a particularly pronounced resistance to the proapoptotic effects of Cisplatin. Quantitative proteome analyses reveal that cycH induces a unique proteomic signature in cervical cancer cells, which includes a significant downregulation of luminal lysosomal proteins. These encompass the potentially proapoptotic cathepsins B and cathepsin L, which, however, appear not to affect the response to Cisplatin under any of the O2 conditions tested. Rather, we show that the proapoptotic Caspase 8/BH3‐interacting domain death agonist (BID) cascade plays a pivotal role for the efficiency of Cisplatin‐induced apoptosis in HPV‐positive cancer cells under all investigated O2 conditions. In addition, we provide evidence that BID activation by Cisplatin is impaired under cycH, which could contribute to the high resistance to the proapoptotic effects of Cisplatin. Collectively, this study provides the first insights into the profound phenotypic alterations induced by cycH in HPV‐positive cancer cells, with implications for their therapeutic susceptibility.

AbstractHuman papillomaviruses (HPV) of the genus Betapapillomavirus can infect both cutaneous and mucosal sites, but research on their natural history at mucosal sites remains scarce. We examined the risk factors and co‐detection patterns of HPVs of the Betapapillomavirus and Alphapapillomavirus genera in cervical samples of the Ludwig‐McGill cohort study. We assessed a subset of 505 women from the Ludwig‐McGill cohort study from São Paulo, Brazil. Cervical samples over the first year of follow‐up were tested for DNA of over 40 alphapapillomavirus types and 43 betapapillomavirus types using a type‐specific multiplex genotyping polymerase chain reaction assay. We assessed the risk factors for prevalent and incident betapapillomavirus type detection, and whether types were detected more frequently together than expected assuming independence using permutation tests, logistic regression, and Cox regression. We observed significant within‐genus clustering but not cross‐genus clustering. Multiple betapapillomavirus types were co‐detected in the same sample 2.24 (95% confidence interval [CI]: 1.65–3.29) times more frequently than expected. Conversely, co‐detections of alphapapillomavirus and betapapillomavirus types in the same sample occurred only 0.64 (95% CI: 0.51–0.83) times as often as expected under independence. In prospective analyses, positivity to one HPV genus was associated with a nonsignificant lower incidence of detection of types in the other genus. Lifetime number of sex partners and new sex partner acquisition were associated with lower risks of prevalent and incident betapapillomavirus detection. Betapapillomaviruses are commonly found in the cervicovaginal tract. Results suggest potentially different mechanisms of transmission for betapapillomavirus genital infections other than vaginal sex.
