A Self‐Assembling Molecule for Improving the Mobility in PEDOT:PSS Hole Transport Layer for Efficient Perovskite Light‐Emitting Diodes
Authors: Kim Tae Hyung , Kim Bong Woo , Im Sang Hyuk 
Published: September 2024

AbstractPoly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), the most widely used hole injection layer (HIL) for perovskite light‐emitting diodes (PeLEDs), has a large hole injection energy barrier and easy charge separation at PEDOT:PSS/perovskite layer. Here, a self‐assembling molecule (SAM) called (2‐(3,6‐dimethoxy‐9H‐carbazol‐9‐yl)ethyl) phosphonic acid (MeO‐2PACz) is introduced as an interlayer between PEDOT:PSS and perovskite to overcome the limitations of PEDOT:PSS HIL. The MeO‐2PACz interlayer facilitated hole injection due to the reduced hole injection energy barrier and the improved hole mobility, enhanced photoluminescence (PL) due to the prevented charge transfer from perovskite into PEDOT:PSS, and reduced interface trap density due to the passivation of methoxy and carbazole group toward perovskite. As a result, PeLEDs with MeO‐2PACz interlayer has greatly enhanced maximum luminance (Lmax = 17,310 cd m−2) and reduced leakage current, resulting in higher maximum external quantum efficiency (EQEmax = 21.50%) compared to pristine Control device (EQEmax of 4.82%).

AbstractIn the field of energy technologies, self‐charging batteries are receiving extensive attention. However, the existing technologies are highly dependent on the available sources of O2, have long self‐charging duration, and have complex architectures. Herein, a novel ultrafast chemical self‐charging Zn‐quinhydrone polymer gel (QPG) battery, composed of acid/base free quinhydrone as a cathode material is reported. The prepared Zn–QPG battery exhibits a specific capacity of 209.7 mAh g−1 at 10C rate and maintains 86.4% of the initial discharge capacity even after 3000 cycles with a high coulombic efficiency of 99.4%. The aqueous amphiphilic block co‐polymer‐driven selective oxidation of hydroquinone (HQ) to benzoquinone (BQ) compels the chemical self‐charging feature wherein the device attains ≈1.1 V within ten minutes of complete discharge. The chemical self‐charging generated a high specific capacity of 197.8 mAh g−1 at 10C rate with a capacity retention of 91.2% after 100 cycles. Moreover, a flexible Zn–QPG battery also demonstrates excellent rechargeability and power‐delivering ability even in a wrist‐bend geometry. This work paves the way to develop ultrafast energy storage systems, which are not dependent on an external power supply and broaden the horizon of aqueous zinc–organic batteries.

Published: September 2024

AbstractVanadate materials are promising for sodium‐ion batteries (SIBs) due to their low cost, high capacity, and high power characteristics enabled by vanadium's multiple oxidation states. However, their development is hindered by poor conductivity, suboptimal high‐rate performance, and limited cycle life. In this work, a layered structure modification strategy involving Ca/F co‐doping in sodium vanadate Na2CaV2O6F (CVF) is proposed to address these issues. Through a combination of experiments and density functional theory calculations, it is demonstrated that Ca/F synergies enhance the Na layer spacing in CVF, resulting in reduced crystal water content and volume shrinkage compared to Na2V2O6 (NVO). Additionally, Ca/F incorporation significantly mitigates the diffusion potential of Na+ within the material framework. The unmodified CVF sample exhibits a high reversible capacity of 220 mAh g−1 at 10 mA g−1 and an excellent rate capacity of 65.78 mAh g−1 at 400 mA g−1. Furthermore, the cathode material maintains a capacity of up to 138 mAh g−1 at 200 mA g−1 and retains 104.88 mAh g−1 after 100 cycles within the voltage range of 1.5−4.0 V. These findings enhance the understanding of the crystal structure of NVO cathode materials and pave the way for the rational design of high‐quality vanadate cathodes for SIBs.

Published: September 2024

AbstractSmall molecule organic materials are widely used as anode materials for lithium‐ion batteries (LIBs) due to their high reversible capacity, designable structure, and environmental friendliness. However, they suffer from poor intrinsic electronic conductivity, severe dissolution, and low initial coulombic efficiency. Recently, metal–organic frameworks (MOFs) have demonstrated in metal‐ion batteries, outperforming some small molecule organic materials in terms of both cycling stability and rate capability. Herein, the first rational design and synthesis of a new cobalt‐based MOF (CoBPDCA), are reported employing cobalt(II) nitrate as the metal source and small organic molecules (2,2‐bipyridyl‐4,4‐dicarboxylic acid, BPDCA) as the ligands, which shows exceptional chemical stability and impressive electron conductivity. Most importantly, CoBPDCA electrodes deliver a high reversible capacity of 1112.9 mAh g−1 at 0.05 C (1 C = 1000 mA g−1) and outstanding high‐rate durability (166.3 mAh g−1 after 2500 cycles at 10 C). Employing a series of spectroscopic and morphological characterizations and density functional theory (DFT) calculations, it is revealed that these impressively electrochemical performances are contributed to the dual active redox centers of Co cations and BPDCA ligands (CN and CO groups), and the superb electron conductivity. This work might provide a new strategy and a deeper understanding of the other MOFs' development for LIBs.
Environmental policy behavioral spillovers: The impact of California's single‐use carryout bag ban on the use of unregulated single‐use plastics
Authors: Yoon Sungeun , House Lisa , Gao Zhifeng 
Published: September 2024

AbstractThis study examines the spillover effect of California's 2016 single‐use bag ban (SB 270) on unregulated single‐use plastics (SUPs) like cutlery, cups, and plates. We observed an insignificant 4.8% decrease in SUP sales over the entire post‐policy period, but a larger 8.1% drop in the second post‐year, which was only marginally significant. The findings suggest weak spillover effects from such environmental policies, indicating that direct regulations on certain environmentally harmful products might be more effective if jurisdictions aim to prohibit citizens from excessive use, rather than relying on the positive spillover effect from existing policies.

Published: September 2024

AbstractAn innovative approach is crucially needed to manage relapse after allogeneic hematopoietic cell transplantation (HCT) in patients with advanced hematological malignancies. This review explores key aspects of haploidentical HCT with post‐transplant cyclophosphamide, highlighting the potential and suitability of this platform for natural killer (NK) cell immunotherapy. NK cells, known for their unique abilities to eliminate cancer cells, can also exhibit memory‐like features and enhanced cytotoxicity when activated by cytokines. By discussing promising results from clinical trials, the review delves into the recent major advances: donor‐derived NK cells can be expanded ex vivo in large numbers, cytokine activation may enhance NK cell persistence and efficacy in vivo, and post‐HCT NK cell infusion can improve outcomes in high‐risk and/or relapsed myeloid malignancies without increasing the risk of graft‐versus‐host disease, severe cytokine release syndrome, or neurotoxicity. Looking ahead, cytokine‐activated NK cells can be synergized with immunomodulatory agents and/or genetically engineered to enhance their tumor‐targeting specificity, cytotoxicity, and persistence while preventing exhaustion. The ongoing exploration of these strategies holds promising preliminary results and could be rapidly translated into clinical applications for the benefit of the patients.

Published: September 2024

AbstractUniquely modified synthetic proteins are difficult to produce in large quantities, which could limit their use in various in vitro settings and in cellular studies. In this study, we developed a method named “suspension bead loading” (SBL), to deliver protein molecules into suspended living cells using glass beads, which significantly reduces the amount of protein required for effective delivery. We investigated the delivery efficiency of functionally different proteins and evaluated the cytotoxic effect of our method and the chemical and functional integrity of the delivered protein. We utilized SBL to address questions related to ubiquitin‐related modifier 1 (URM1). Employing minimal protein quantities, SBL has enabled us to study its behavior within live cells under different redox conditions, including subcellular localization and conjugation patterns. We demonstrate that oxidative stress alters both the localization and conjugation pattern of URM1 in cells, highlighting its possible role in cellular response to such extreme conditions.
How environmental accidents influence consumer “green” behavior: An econometric analysis
Authors: Hardcopf Rick , Dhanorkar Suvrat 
Published: September 2024

AbstractEnvironmental accidents (EAs) are firm operational failures that harm human health, the natural environment, and offending firms. We propose they also initiate a subtle form of activism among consumers living near the accident by stimulating increased “green” behavior. Using annual county‐level data in California from 2000 to 2015, we show that following an EA, consumers reduce the trash/garbage they generate and the energy they consume. The impact is long‐lasting and stronger when EAs are more severe and when consumers have pro‐environmental beliefs, ready access to information, and convenient access to “green” options, such as recycling. Since affected consumers may also refuse to buy from, invest in, or work for offending companies, the results suggest that firms should develop environmental strategies, which include engaging and collaborating with local communities. The study results also provide input for the development of initiatives, which maximize consumer “green” behavior after, or in the absence of, an EA.

AbstractIn medical education, traditional anatomy labs have relied heavily on the hands‐on dissection of cadavers to teach the complex spatial relationships within the human body. However, the advent of virtual reality (VR) technology offers the potential for significantly enhancing this traditional approach by providing immersive, interactive 3D visualizations that can overcome some of the limitations of physical specimens. This study explores the integration of VR into a traditional gross anatomy lab to enrich the learning experience for medical students. Methods included the deployment of a VR application developed to complement the dissection process, featuring detailed 3D models of human anatomy that students could manipulate and explore digitally. Approximately 60 s‐year medical students participated in the lab, where they engaged with both traditional dissection and the VR application. Results indicated that the VR integration not only increased engagement and satisfaction but also improved the students' ability to understand anatomical structures and their spatial relationships. Moreover, feedback from students suggested more efficient learning and retention than with traditional methods alone. We conclude that VR technology can significantly enhance medical anatomy education by providing an adjunct to traditional dissection, potentially replacing certain aspects of physical specimens with digital simulations that offer repeatable, detailed exploration without the associated logistical and ethical constraints.

Published: September 2024

AbstractThis work introduces a novel method of recovering bioactive berry natural products (BNPs) using solid phase extraction with metal‐organic frameworks (MOF‐SPE). Two pyrene‐based MOFs with different structural topologies, Al‐PyrMOF and Zr‐NU‐1000, were evaluated for their ability to capture and desorb BNPs, including ellagic acid, quercetin, gallic acid, and p‐coumaric acid. Time‐dependent BNP uptake via dispersive SPE revealed that NU‐1000 outperformed Al‐PyrMOF in capturing all BNPs. Our findings show NU‐1000 demonstrated a higher and more consistent BNP capture profile, achieving over 90 % capture of all BNPs within 36 h, with only a 9 % variation between the most and least effectively captured BNPs. In contrast, Al‐PyrMOF, displayed a staggered uptake profile, with a significant 53 % difference in capture efficiency between the most and least effectively captured BNP. However, when a BNP mixture was used at a loading concentration of 50 μg/mL, Al‐PyrMOF outperformed NU‐1000, capturing over 70 % of all BNPs. Al‐PyrMOF also exhibited improved BNP recovery, with a minimum of two‐fold greater amount recovered for all BNPs. Further testing with a BNP mixture at a concentration of 15 μg/mL demonstrated that Al‐PyrMOF efficiently concentrated all BNPs, achieving a maximum extraction factor of 2.71 observed for quercetin. These findings highlight the use of Al‐PyrMOF as a MOF‐SPE sorbent for recovering bioactive BNPs.

Published: September 2024

AbstractFor the first time, explicit stabilization of all the three conformers, viz. (cis,cis), (cis,trans) and (trans,trans), of a ‘nano‐sized’ highly‐flexible urea‐bridged Zn(II)porphyrin dimer have been achieved via careful manipulations of external stimuli such as solvent dielectrics, temperature, anionic interactions, axial ligation and surface‐induced stabilization. The conformers differ widely in their structures, chemical and photophysical properties and thus have vast potential applicability. X‐ray structural characterizations have been reported for the (cis,cis) and (cis,trans)‐conformers. While (cis,cis) conformer stabilized exclusively in dichloromethane, more polar solvents resulted in the stabilization of (cis,trans) and (trans,trans)‐conformers. Low temperature promotes the stabilization of (cis,trans)‐conformer while rise in temperature facilitates flipping to the (cis,cis) one. Significantly, exclusive stabilization of the (trans,trans)‐isomer has been illustrated using acetate anion which facilitates H‐bonding with the two amide linkages of the urea spacer. Remarkably, HOPG surface facilitates stabilization of the energetically challenging (trans,trans)‐conformer via CH⋅⋅⋅π and π⋅⋅⋅π interactions with the solid surface to the porphyrinic cores. DFT calculations demonstrate that the relative stability of the conformers can be modulated upon slight external perturbations as also observed in the experiment. Several factors contributing towards the conformational landscape for the highly flexible urea‐bridged porphyrin dimers have been mapped.

AbstractBackgroundThe psychological and cardiovascular health impacts on family members of patients who have been diagnosed with cancer have not been well characterized. The purpose of this study is to determine whether a family member’s cancer diagnosis influences the risk of psychological illness and cardiovascular disease in first‐degree relatives and spouses of patients affected by cancer.MethodsThis retrospective cohort analysis evaluated the risk of psychological illness and cardiovascular disease in first‐degree relatives and spouses of patients diagnosed with a genitourinary cancer between 1990 and 2015 compared to relatives of those not diagnosed with a genitourinary cancer. The Utah Population Database was used and familial linkage was determined. Follow‐up included 1‐, 3‐, and 5‐year intervals. Patients residing outside of Utah and first‐degree relatives and spouses with psychological or cardiovascular disease diagnosed before a family member’s cancer diagnosis were excluded.ResultsA total of 49,284 patients with a genitourinary cancer were identified with 77,938 first‐degree relatives and spouses. A matched control group included 246,775 patients with 81,022 first‐degree relatives and spouses. Via Cox proportional hazards models, a 10% increased risk of developing a psychological illness (hazard ratio [HR], 1.10; 95% CI, 1.00–1.20) and a 28% increased risk of developing cardiovascular disease (HR, 1.28; 95% CI, 1.17–1.41) at 1 year after a family member’s cancer diagnosis were found.ConclusionsThis study provides population‐level evidence to support the hypothesis that cancer diagnoses will lead to adverse health outcomes for family members of patients with cancer. Increased clinical attention and support are needed to reduce the harm to families caused by cancer.
The Influence of Halogen Anions on the Color/Fluorescence Dual‐Switching Behaviors of 1,10‐Phenanthroline‐Based Viologen Derivatives
Authors: Zhuang Yanling , Zhang Qidong , Lin Xiaquan 
Published: September 2024

AbstractStimuli‐responsive color/fluorescence dual‐switchable materials have garnered significant attention in displays, sensors, and anti‐counterfeiting. However, current material systems are hampered by the single stimulus‐response and unregulated fluorescence. Viologen derivatives featuring fluorophore as N‐substituent and halogen anions as counteranions not only exhibit responsiveness to both electric and light stimuli but also enable adjustable emission. In this work, we explored the influence of halogen anions on the color/fluorescence dual‐switching behaviors of 1,10‐phenanthroline‐based viologen derivatives. The energy level gaps for phen‐Vio[2Cl−] (2.93 eV), phen‐Vio[2Br−] (2.67 eV), and phen‐Vio[2I−] (2.34 eV) decreased with the decrease of electron affinity of halogen anions (Cl−>Br−>I−), which leads to a sequential improvement in their electrochromic/electrofluorochromic and photochromic/photofluorochromic properties. This work has important guidance for the design and development of smart materials and their optoelectronic devices.

Published: September 2024

AbstractA series of copper hydroxyphosphate (Cu2(OH)PO4) microcrystals with different shapes, including straw sheaf‐like microcrystals, microrods‐assembled microflowers, four‐edged arrow‐like microcrystals, and four‐pointed star‐like dendrites, are prepared by a hydrothermal method in Na2HPO4‐NaOH buffer solutions. The buffer solutions serve as both reactant and solvent. More importantly, the pH values of the alkaline buffer solutions significantly affect the morphologies of Cu2(OH)PO4 microcrystals. Four samples have absorption bands in the near‐ultraviolet, visible, and near‐infrared regions; furthermore, four Cu2(OH)PO4 microcrystals exhibit different band gap energies (3.06, 2.78, 2.68, and 2.39 eV) owing to their different structures. This strategy can be scaled up for the simple, green, and low‐cost production of Cu2(OH)PO4 microcrystals.

Published: September 2024

AbstractErythrophagocytosis is a process consisting of recognition, engulfment and digestion by phagocytes of antibody‐coated or damaged erythrocytes. Understanding the dynamics that are behind erythrophagocytosis is fundamental to comprehend this cellular process under specific circumstances. Several techniques have been used to study phagocytosis. Among these, an interesting approach is the use of Imaging Flow Cytometry (IFC) to distinguish internalization and binding of cells or particles. However, this method requires laborious analysis. Here, we introduce a novel approach to analyze the phagocytosis process by combining Artificial Intelligence (AI) with IFC. Our study demonstrates that this approach is highly suitable to study erythrophagocytosis, categorizing internalized, bound and non‐bound erythrocytes. Validation experiments showed that our pipeline performs with high accuracy and reproducibility.

Published: September 2024

SummaryUnstructured peer‐to‐peer (P2P) networks pose unique challenges for efficient and scalable routing. In this study, we introduce a novel routing algorithm inspired by the foraging behavior of honey bees named Honey Bee Optimization in P2P Networks (HBO_P2P) to address the inherent limitations of routing in unstructured P2P networks, focusing on improving packet delivery, minimizing hop count, reducing message overhead, and optimizing overall throughput. To evaluate the performance of our proposed algorithm, we conducted comprehensive experiments comparing it with existing algorithms commonly used in P2P networks, namely, particle swarm optimization (PSO), genetic algorithm (GA), and ant colony optimization (ACO). After the simulation, we got the results as follows: Our algorithm outperforms ACO, GA, and PSO by exhibiting the highest number of data hops indicating potential efficiency in route optimization. Routing overhead is also minimal as compared to ACO, GA, and PSO. The average data packet delay is also low in our algorithm as compared to ACO, GA, and PSO. HBO_P2P achieves the highest throughput, nearly reaching 100 Mbps. While ACO and GA exhibit similar throughput of around 80 Mbps, and PSO has the lowest throughput, approximately 60 Mbps.
