AbstractRecently, organic–inorganic metal halide perovskite solar cells (PSCs) have achieved rapid improvement, however, the efficiencies are still behind the Shockley–Queisser theory mainly due to their high energy loss (ELOSS) in open‐circuit voltage (VOC). Due to the polycrystalline nature of the solution‐prepared perovskite films, defects at the grain boundaries as the non‐radiative recombination centers greatly affect the VOC and limit the device efficiency. Herein, poly(vinylidene fluoride) (PVDF) is introduced as polymer‐templates in the perovskite film, where the fluorine atoms in the PVDF network can form strong hydrogen‐bonds with organic cations and coordinate bonds with Pb2+. The strong interaction between PVDF and perovksite enables slow crystal growth and efficient defect passivation, which effectively reduce non‐radiation recombination and minimize ELOSS of VOC. PVDF‐based PSCs achieve a champion efficiency of 24.21% with a excellent voltage of 1.22 V, which is one of the highest VOC values reported for FAMAPb(I/Br)3‐based PSCs. Furthermore, the strong hydrophobic fluorine atoms in PVDF endow the device with excellent humidity stability, the unencapsulated solar cell maintain the initial efficiency of >90% for 2500 h under air ambient of ≈50% humid and a consistently high VOC of 1.20 V.

AbstractRu has recently been considered as a promising alternative of Pt toward hydrogen oxidation reaction (HOR) due to its lower price and similar hydrogen binding energy (HBE) in comparison to Pt. Nevertheless, the catalytic performance of Ru toward HOR is far from the satisfaction of practical application. Herein, it is demonstrated that the modification of Ru multi‐layered nanosheet (MLNS) with Ni can significantly promote the HOR performance. In particular, the HOR performance is strongly related to the Ni location on the surface or in the lattice of Ru MLNS. Experimental and theoretical investigations suggest that Ni in the lattice of Ru MLNS (lattice engineering) optimizes the HBE, while Ni species on the surface (surface engineering) decrease the free energy of water formation, as a result of the significantly enhanced HOR performance. The optimal catalyst, where Ni is located both on the surface and in the lattice, displays superior alkaline HOR performance to commercial Pt/C and Ru/C. The present study not only systematically reveals the significance of Ni modification on Ru toward HOR, but also promotes the fundamental researches on catalyst design for fuel cell reactions and beyond.

AbstractIt is still a great challenge to obtain multicolor tunable luminescence and improve the stability of luminescence through reasonable design of materials in the field of white light‐emitting diodes (WLEDs). In particular, it is more important to improve the luminescence intensity and stability of blue‐emitting materials. Here, the properties of CsPbBr3, CsPbBr3:Na, and NaPbBr3 are investigated theoretically by using density functional theory (DFT). Based on the DFT theoretical calculation results, it is assumed that unexpected performance may be achieved by replacing Cs in CsPbBr3 with Na or passivating the surface of CsPbBr3 with Na. As expected, the tunable luminescence from blue to green is successfully achieved from CsPbBr3:Na, and the stability is improved. After experimental optimization, the obtained CsPbBr3:Na (CPBN‐4) with high luminescence stability is used as blue‐emitting materials to construct the WLED devices with excellent color quality (CRI 92) and correlated color temperature of 9582 K.

AbstractCycling lithium cobalt oxide (LiCoO2) to a potential higher than 4.35 V (vs Li+/Li) can obtain an enticing capacity, but suffers from inferior structural stability. Herein, an ingenious Li‐deintercalation/doping strategy is developed to synthesize the lanthanide‐doped LiCoO2 (lanthanide (Ln) = praseodymium, neodymium, samarium, europium, gadolinium, erbium, or lutetium) with Ln occupying Li‐sites. Electrochemical measurements show that the cycling stability of Ln‐doped LiCoO2 increases as the lanthanide contracts. By rule, lutetium‐doped LiCoO2 exhibits the best cycling stability, confirmed in both lithium half‐cell and pouch full‐cell. Comprehensive experimental characterizations combining with theoretical calculations reveal that the lattice strain tuned by the lanthanide contraction plays a critical role in the structure stability of LiCoO2. This finding is an important step for building better high‐voltage LiCoO2 batteries, as it is possible to achieve better high‐voltage performance by combining the doping technology and performance improvement rule disclosed in this study.

Published: December 2022

AbstractThe development of flexible strain sensors over the past decade has focused on accessing high strain percentages and high sensitivity (i.e., gauge factors). Strain sensors that employ capacitance as the electrical signal to correlate to strain are typically restricted in sensitivity because of the Poisson effect. By employing auxetic structures, the limits of sensitivity for capacitive sensors have been exceeded, which has improved the competitiveness of this modality of sensing. In this work, the first employment of helical auxetic yarns as capacitive sensors is presented. It is found that the response of the helical auxetic yarn capacitive sensors (termed as HACS) is dependent on the two main fabrication variables—the ratio of diameters and the helical wrapping length. Depending on these variables, sensors that respond to strain with increasing or decreasing capacitance values can be obtained. A greater auxetic character results in larger sensitivities accessible at smaller strains—a characteristic that is not commonly found when accessing high gauge factors. In addition, the highest sensitivity for auxetic capacitive sensors reported thus far is obtained. A mechanism of sensor response that explains both the variable capacitance response and the high gauge factors obtained experimentally is proposed.

AbstractTumor cells are dominant in the nutritional competition in the tumor microenvironment, and their metabolic abnormalities often lead to microenvironmental acidosis and nutrient deprivation, thereby impairing the function of immune cells and diminishing the antitumor therapeutic effect. Herein, a branched polymeric conjugate and its efficacy in attenuating the metabolic competition of tumor cells are reported. Compared with the control nanoparticles prepared from its linear counterpart, the branched‐conjugate‐based nanoparticles can more efficiently accumulate in the tumor tissue and interfere with the metabolic processes of tumor cells to increase the concentration of essential nutrients and reduce the level of immunosuppressive metabolites in the TME, thus creating a favorable environment for infiltrated immune cells. Its combined treatment with an immune checkpoint inhibitor (ICI) achieves an enhanced antitumor effect. The work presents a promising approach for targeting metabolic competition in the TME to enhance the chemo‐immunotherapeutic effect against cancers.

AbstractThe reverse intersystem crossing (RISC) process from triplet to singlet manifold can efficiently improve the efficiencies of organic light‐emitting diodes (OLEDs). The relevant RISC rate (kRISC) is one of the key factors that affect the efficiency roll‐off and stability of devices. Here, a new blue “hot exciton” material, CPPCN, with pyrene as the core, is designed and synthesized. Photophysical studies indicate there are multiple high‐lying triplet states near the lowest singlet excited state (S1) of CPPCN, which facilitate the RISC from the high‐lying triplet state (hRISC) to the S1 state. The corresponding hRISC rate constant is determined to be as high as 2.86 × 108 s−1, a value some two to three orders of magnitude higher than typical thermally activated delayed fluorescence materials emitters. Benefiting from this ultrafast hRISC process, non‐doped blue OLED based on CPPCN reaches a high maximum external quantum efficiency (EQE) of 11.64% with suppressed efficiency roll‐off (begin roll‐off at a high brightness of 3732 cd m−2 and retains EQE >8.5% at 10 000 cd m−2). The T95 lifetime of the CPPCN‐based device with a structure of commercial applications is evaluated to be ≈368 h at 1000 cd m−2.

AbstractNiche for stem cells profoundly influences their maintenance and fate during tissue homeostasis and pathological disorders; however, the underlying mechanisms and tissue‐specific features remain poorly understood. Here, it is reported that fatty acid desaturation catabolized by stearoyl‐coenzyme A desaturase 1 (SCD1) regulates hair follicle stem cells (HFSCs) and hair growth by maintaining the bulge, niche for HFSCs. Scd1 deletion in mice results in abnormal hair growth, an effect exerted directly on keratin K14+ keratinocytes rather than on HFSCs. Mechanistically, Scd1 deficiency impairs the level of integrin α6β4 complex and thus the assembly of hemidesmosomes (HDs). The disruption of HDs allows the aberrant activation of focal adhesion kinase and PI3K in K14+ keratinocytes and subsequently their differentiation and proliferation. The overgrowth of basal keratinocytes results in downward extension of the outer root sheath and interruption of bulge formation. Then, inhibition of PI3K signaling in Scd1−/− mice normalizes the bulge, HFSCs, and hair growth. Additionally, supplementation of oleic acid to Scd1−/− mice reestablishes HDs and the homeostasis of bulge niche, and restores hair growth. Thus, SCD1 is critical in regulating hair growth through stabilizing HDs in basal keratinocytes and thus sustaining bulge for HFSC residence and periodic activity.

AbstractThe highly heterogeneous characteristics of Wharton's jelly mesenchymal stem cells (WJ‐MSCs) may be responsible for the poor clinical outcomes and poor reproducibility of treatments based on WJ‐MSCs. Exploration of WJ‐MSC heterogeneity with multimodal single‐cell technologies will aid in establishing accurate MSC subtyping and developing screening protocols for dominant functional subpopulations. Here, the characteristics of WJ‐MSCs are systematically analyzed by single cell and spatial transcriptome sequencing. Single‐cell transcriptomics analysis identifies four WJ‐MSC subpopulations, namely proliferative_MSCs, niche‐supporting_MSCs, metabolism‐related_MSCs and biofunctional‐type_MSCs. Furthermore, the transcriptome, cellular heterogeneity, and cell‐state trajectories of these subpopulations are characterized. Intriguingly, the biofunctional‐type MSCs (marked by S100A9, CD29, and CD142) selected in this study exhibit promising wound repair properties in vitro and in vivo. Finally, by integrating omics data, it has been found that the S100A9+CD29+CD142+ subpopulation is more enriched in the fetal segment of the umbilical cord, suggesting that this subpopulation deriving from the fetal segment may have potential for developing into an ideal therapeutic agent for wound healing. Overall, the presented study comprehensively maps the heterogeneity of WJ‐MSCs and provides an essential resource for future development of WJ‐MSC‐based drugs.

AbstractMitochondria are the powerhouse of eukaryotic cells, which regulate cell metabolism and differentiation. Recently, mitochondrial transfer between cells has been shown to direct recipient cell fate. However, it is unclear whether mitochondria can translocate to stem cells and whether this transfer alters stem cell fate. Here, mesenchymal stem cell (MSC) regulation is examined by macrophages in the bone marrow environment. It is found that macrophages promote osteogenic differentiation of MSCs by delivering mitochondria to MSCs. However, under osteoporotic conditions, macrophages with altered phenotypes, and metabolic statuses release oxidatively damaged mitochondria. Increased mitochondrial transfer of M1‐like macrophages to MSCs triggers a reactive oxygen species burst, which leads to metabolic remodeling. It is showed that abnormal metabolism in MSCs is caused by the abnormal succinate accumulation, which is a key factor in abnormal osteogenic differentiation. These results reveal that mitochondrial transfer from macrophages to MSCs allows metabolic crosstalk to regulate bone homeostasis. This mechanism identifies a potential target for the treatment of osteoporosis.

AbstractIntroductionThe current study evaluated the use of platelet‐rich plasma (PRP), an autologous blood product with supraphysiologic concentrations of growth factors, in the treatment of prolonged coronavirus disease 2019 (COVID‐19)–related smell loss.MethodsThis multi‐institutional, randomized controlled trial recruited patients with COVID‐19 who had objectively measured smell loss (University of Pennsylvania Smell Identification Test [UPSIT] ≤ 33) between 6 and 12 months. Patients were randomized to three intranasal injections of either PRP or sterile saline into their olfactory clefts. The primary outcome measure was change in Sniffin’ Sticks score (threshold, discrimination, and identification [TDI]) from baseline. The secondary end point measures included responder rate (achievement of a clinically significant improvement, ≥5.5 points TDI), change in individual TDI olfaction scores, and change in subjective olfaction via a visual analog scale.ResultsA total of 35 patients were recruited and 26 completed the study. PRP treatment resulted in a 3.67‐point (95% CI: 0.05–7.29, p = 0.047) greater improvement in olfaction compared with the placebo group at 3 months and a higher response rate (57.1% vs 8.3%, odds ratio 12.5 [95% exact bootstrap confidence interval, 2.2–116.7]). There was a greater improvement in smell discrimination following PRP treatment compared with placebo but no difference in smell identification or threshold. There was no difference in subjective scores between PRP and placebo. No adverse effects were reported.ConclusionOlfactory function following COVID‐19 can improve spontaneously after 6 months and can improve to a greater extent with PRP injection. These data build on the promise of PRP to be a safe potential treatment option for patients with COVID‐19–related smell loss, and larger‐powered studies will help further assess its efficacy.

Published: December 2022

Palladium catalyst supported on chitosan‐EDTA composite, CS‐EDTA‐Pd, was prepared by a simple dissolution method. The chitosan and EDTA (1:1.5 by wt.) were dissolved in dilute acetic acid, then formed the beads, which were used to adsorb palladium(II) and finally reduced to palladium(0) by refluxing in ethanol. The as‐prepared CS‐EDTA‐Pd was characterized by Fourier transform infrared (FT‐IR) spectroscopy, scanning electron microscopy (SEM), energy dispersive X‐ray spectrometry (EDX), and X‐ray photoelectron spectroscopy (XPS). Then catalytic activities of the CS‐EDTA‐Pd catalyst were tested in the synthesis of biaryls from aryl halides and phenylboronic acid using the Suzuki–Miyaura cross‐coupling reaction. The results have shown that the CS‐EDTA‐Pd was successfully applied as a catalyst for the Suzuki–Miyaura to couple aryl iodide and aryl bromide substrates under mild reaction conditions using ethanol as solvent and potassium carbonate as a base. The reactions at 80°C for 2 h under a normal atmosphere results in biaryls at good to excellent yields (>90%). This catalyst is inexpensive, simple to prepare, easy to separate from the reaction by filtration, and can be reused for five consecutive runs with a slight loss of product yields.

AbstractIn this study, we explore sustainable business model (SBM) research through the lens of doughnut economics (DE). By conducting an integrative literature review, we analyse concepts that reflect the seven principles of DE at the business model level. We identify 23 SBM concepts and develop a framework that draws on cognitive science theory to distinguish between seven abstract and 16 concrete concepts. The contribution of our study is threefold: First, the framework enhances the theoretical understanding of SBM concepts that mirror DE. Second, our study presents seven unique avenues for shifting the SBM research agenda. Third, the findings have the potential to inspire SBM innovation in practice.

Published: December 2022

AbstractThe business world is becoming increasingly complex, disrupted, and uncertain. As Industry 4.0 (I4.0) takes shape, to endure this change and focus on growth, industries must learn to embrace change and move quickly; this is particularly so for the automotive industry, which is a major sector of any economy. Agility is needed to embrace this change and promote sustainability across every industry. To face these contingencies, it is essential to identify and understand the strategies that can aid industries in sustaining real‐time scenarios. In this paper, we aim to assess the agility indicators that bring resilience to the inclusion of I4.0 and sustainability in the automotive sector. The unexpected changes in the environment related to sustainability and technological disruptions of I4.0 require the identification of sustainable agile mitigation strategies to manage such situations. The fuzzy Delphi methodology assesses agility indicators based on a questionnaire for prioritization. Further, the fuzzy technique for order performance by similarity to ideal solution (TOPSIS) is utilized to prioritize these agility indicators with the agility strategies that manufacturing industries can deploy to enhance the sustainability of their operations. The fuzzy extension to the methodologies helps in incorporating vagueness and ambiguity in the decision‐making process. A fuzzy approach to prioritizing agile strategies as the industries are changing is helpful. The decision makers have only a few clear ideas about how best to integrate them. Among the agile strategies, “resilience,” “technological capabilities,” and “customer‐centric innovation” are the top strategies. By executing the strategies suggested in the study and understanding the agility indicators, practitioners can ensure resilience in the work systems and minimize the impact of the disruptions caused by the industrial revolution. Thus, this research has been underpinned by the organizational change theory and discusses all mitigation strategies concerning the rapid changes organizations are facing with the fourth industrial revolution.
