AbstractIdeal bandgap (1.3–1.4 eV) Sn‐Pb mixed perovskite solar cells (PSC) hold the maximum theoretical efficiency given by the Shockley–Queisser limit. However, achieving high efficiency and stable Sn‐Pb mixed PSCs remains challenging. Here, piperazine‐1,4‐diium tetrafluoroborate (PDT) is introduced as spacer for bottom interface modification of ideal bandgap Sn‐Pb mixed perovskite. This spacer enhances the quality of the upper perovskite layer and forms better energy band alignment, leading to enhanced charge extraction at the hole transport layer (HTL)/perovskite interface. Then, 2D Ti3C2Tx MXene is incorporated for surface treatment of perovskite, resulting in reduced surface trap density and enhanced interfacial electron transfer. The combinations of double‐sided treatment afford the ideal bandgap PSC with a high efficiency of 20.45% along with improved environment stability. This work provides a feasible guideline to prepare high‐performance and stable ideal‐bandgap PSCs.

AbstractThe developed strategies for synthesizing metal phosphides are usually cumbersome and pollute the environment. In this work, an ultrafast (30 s) quasi‐solid‐state microwave approach is developed to construct cobalt–molybdenum phosphide decorated with Ru (Ru/CoxP‐MoP) featured porous morphology with interconnected channels. The specific nanostructure favors mass transport, such as electrolyte bubbles transfer and exposing rich active sites. Moreover, the coupling effects between metallic elements, especially the decorated Ru, also act as a pivotal role on enhancing the electrocatalytic performance. Benefiting from the effects of composition and specific nanostructure, the prepared Ru/CoxP‐MoP exhibits efficient HER performance with a current density of 10 mA cm−2 achieved in 1 m KOH, 0.5 m H2SO4, seawater containing 1 m KOH and 1 m PBS, with overpotentials of 52, 59, 55, 90 mV, and coupling with good stability. This work opens a novel and fast avenue to design metal‐phosphide‐based nanomaterials in energy‐conversion and storage fields.
Revealing the Thermodynamic Mechanism of Phase Transition Induced by Activation Polarization in Lithium‐Ion Batteries

Published: August 2024

AbstractEnhancing the phase transition reversibility of electrode materials is an effective strategy to alleviate capacity degradation in the cycling of lithium‐ion batteries (LIBs). However, a comprehensive understanding of phase transitions under microscopic electrode dynamics is still lacking. In this paper, the activation polarization is quantified as the potential difference between the applied potential (Uabs) and the zero‐charge potential (ZCP) of electrode materials. The polarization potential difference facilitates the phase transition by driving Li‐ion adsorption and supplying an electron‐rich environment. A novel thermodynamic phase diagram is constructed to characterize the phase transition of the example MoS2 under various Li‐ion concentrations and operating voltages using the grand canonic fixed‐potential method (FPM). At thermodynamic quasi‐equilibrium, the ZCP is close to the Uabs, and thus is used to form the discharge curve in the phase diagram. The voltage plateau is observed within the phase transition region in the simulation, which will disappear as the phase transition reversibility is impaired. The obtained discharge curve and phase transition concentration both closely match the experimental results. Overall, the study provides a theoretical understanding of how polarization affects phase evolution in electrode dynamics, which may provide a guideline to improve battery safety and cycle life.

AbstractThe advancement of acceptors plays a pivotal role in determining photovoltaic performance. While previous efforts have focused on optimizing acceptor–donor–acceptor1–donor–acceptor (A–DA1–D–A)‐typed acceptors by adjusting side chains, end groups, and conjugated extension of the electron‐deficient central A1 unit, the systematic exploration of the impact of peripheral aryl substitutions, particularly with different electron groups, on the A1 unit and its influence on device performance is still lacking. In this study, three novel acceptors – QxTh, QxPh, and QxPy – with distinct substitutions on the quinoxaline (Qx) are designed and synthesized. Density functional theory (DFT) analyses reveal that QxPh, featuring a phenyl‐substituted Qx, exhibits the smallest molecular binding energies and a tightest π···π stacking distance. Consequently, the PM6:QxPh device demonstrates a better power conversion efficiency (PCE) of 17.1% compared to the blends incorporating QxTh (16.4%) and QxPy (15.7%). This enhancement is primarily attributed to suppressed charge recombination, improved charge extraction, and more favorable molecular stacking and morphology. Importantly, introducing QxPh as a guest acceptor into the PM6:BTP‐eC9 binary system yields an outstanding PCE of 19.5%, indicating the substantial potential of QxPh in advancing ternary device performance. The work provides deep insights into the expansion of high‐performance organic photovoltaic materials through peripheral aryl substitution strategy.

Published: August 2024

AbstractNanotizing biosealant components offer a multitude of chemical functionalities for superior adhesion–cohesion, delivering unique properties for comprehensive wound healing that are otherwise impossible to achieve using commercial variants. For the first time, a two‐step controlled hydrothermal pyrolysis is reported to nanotize dopamine, phloroglucinol, and glutaraldehyde into carbon dot (CD) to be subsequently converted into carbonized polymer dot (CPD) with gelatin as a co‐substrate. Chemical crosslinking of CD with gelatin through Schiff base formation before the second pyrolysis step ensures a complex yet porous polymeric network. The retention of chemical functionalities indigenous to CD substrates and gelatin along with the preservation of CD photoluminescence in CPD for optical tracking is achieved. A unique nanoformulation is created with the CPD through tannic acid (TA) grafting evolving CPD‐TA nanoglue demonstrating ≈1.32 MPa strength in lap shear tests conducted on porcine skin, surpassing traditional bioadhesives. CPD‐TA nanoglue uploaded insulin as chosen cargo disbursal at the wound site for healing normal and in vitro diabetic wound models using HEKa cells with extraordinary biocompatibility. Most importantly, CPD‐TA can generate reactive oxygen species (ROS) and scavenge simultaneously under ambient conditions (23 W white LED or dark) for on‐demand sterilization or aiding wound recovery through ROS scavenging.

Published: August 2024

AbstractPhotocatalytic H2O2 production is a green and sustainable route, but far from meeting the increasing demands of industrialization due to the rapid recombination of the photogenerated charge carriers and the sluggish reaction kinetics. Effective strategies for precisely regulating the photogenerated carrier behavior and catalytic activity to construct high‐performance photocatalysts are urgently needed. Herein, a nitrogen‐site engineering strategy, implying elaborately tuning the species and densities of nitrogen atoms, is applied for H2O2 photogeneration performance regulation. Different nitrogen heterocycles, such as pyridine, pyrimidine, and triazine units, are polymerized with trithiophene units, and five covalent organic frameworks (COFs) with distinct nitrogen species and densities on the skeletons are obtained. Fascinatingly, they photocatalyzed H2O2 production via dominated two‐electron O2 reduction processes, including O2‐O2•‒‐H2O2 and O2‐O2•‒‐O21‐H2O2 dual pathways. Just in the air and pure water, the multicomponent TTA‐TF‐COF with the maximum nitrogen densities triazine nitrogen densities exhibited the highest H2O2 production rate of 3343 µmol g−1 h−1, higher than most of other reported COFs. The theoretical calculation revealed the higher activity is due to the easy formation of O2•‒ and O21 in different catalytic process. This study gives a new insight into designing photocatalysis at atomic level.
Enriching systems practice with African perspectives
Authors: Njenga Samuel Gikaru , Massyn Liezel 
Published: August 2024

AbstractThis paper follows an autoethnographic approach that seeks to give a practitioner's reflection by exploring the intersection between African philosophies, particularly the concepts of Ubuntu and Ukama, and the practice of systems thinking. It raises concern about the absence of an African perspective in the discourse on mainstream systems thinking approaches. It argues that African philosophies, with their emphasis on relationality, community and humanness, can contribute to and enrich the discourse on developing systems thinking approaches. The main author's positionality, including his struggles with his identity as an African, his personal experiences growing up in a rural African village and being exposed to traditional African storytelling and community‐based practices, is used to illustrate the connections between African philosophies and systems thinking. As an example of this linkage and how an African perspective can enrich the practice of systems thinking, the paper applies an African worldview to Critical Systems Heuristics.

Published: August 2024

ABSTRACTA robust and reproducible HPLC–UV‐based bioanalytical method for acalabrutinib (ACP) was developed and validated in rat plasma using prednisone as internal standard. The samples were prepared by single‐step protein precipitation method using methanol with 1% v/v formic acid. A polar C18 stationary phase was used with a combination of 10 mM ammonium acetate (pH 3.5) and methanol (60:40 ratio), flow rate 1.1 mL/min, and 50 µL injection volume. ACP and internal standard were retained at ∼5.96 and 8.29 min, respectively. The method was validated according to the United States Food and Drug Administration and ICH M10 bioanalytical method validation guidelines. It was linear in the calibration range (0.08–5 µg/mL) with as 0.9989; accurate (% bias ≤ 0.50 ± 0.67), and precise (%RSD ≤ 0.986) for any quality control standard. Further, the method was applied in estimating ACP in rat plasma samples collected during in vivo pharmacokinetic study of the bulk drug as well as a nanocrystal (NC) suspension formulation. ACP‐NCs were formulated by bottom‐up solvent–antisolvent precipitation with mean particle size 266.32 ± 29.90 nm, 0.25 ± 0.05 PDI, with 92.7% ± 2.3% yield. The NC formulation improved both in vitro dissolution and in vivo absorption, supporting a further development of ACP‐loaded nanodrug delivery systems.

AbstractBackgroundTerbinafine has been successfully used in the treatment of human sporotrichosis; however, its effectiveness in the treatment of feline sporotrichosis is unknown. Therefore, this study aimed to describe the use of terbinafine in the treatment of feline sporotrichosis.MethodsA cohort study was conducted in cats with sporotrichosis to assess the effectiveness and safety of terbinafine (30‒60 mg/kg/day). Clinical examination and analysis of laboratory parameters were performed monthly until clinical signs resolved or terbinafine treatment was discontinued.ResultsOf the 54 cats with sporotrichosis included in the study, 19 were lost during follow‐up and five were withdrawn from the study due to switching to treatment with another prescription drug. Of the remaining 30 cats, 10 achieved clinical cure, with a median treatment time of 18.5 weeks. Treatment failed in 18 cases, and two cats died. Twenty‐two cats had adverse reactions to terbinafine treatment, and 10 cats showed elevation of serum transaminases.LimitationLoss during follow‐up was high, which makes it difficult to draw accurate conclusions regarding clinical outcomes.ConclusionThe low rate of clinical cure observed suggests that terbinafine does not represent an effective treatment option for cases of feline sporotrichosis.

Authors: Bergmann Franziska , Westgren Frida , Elmén Annika , Lee Marcel 
Published: August 2024

AbstractAn 11‐month‐old, entire, male greyhound dog was presented with a 2‐day history of vomiting, lethargy and abdominal pain. An abdominal ultrasound and a computed tomography study were performed revealing images compatible with isolated gall bladder torsion. Surgery confirmed a twisted floating gall bladder, and a cholecystectomy was performed. The dog recovered without any complications. Gall bladder torsion is a rare but potentially life‐threatening condition in veterinary medicine, and a prompt diagnosis preoperatively is valuable. This is the first reported case of preoperative diagnosis of isolated gall bladder torsion by diagnostic imaging in veterinary medicine.

Published: August 2024

AbstractA 3‐year‐old, female, spayed, mixed breed dog developed progressive dyspnoea after exposure to waterproofing shoe spray. The dog developed severe hypoxaemia and hypercapnia, and was subsequently diagnosed with veterinary acute respiratory distress syndrome secondary to chemical pneumonitis. Mechanical ventilation was initiated due to respiratory compromise. Severe hypercapnia persisted despite aggressive treatment. Unfortunately, the patient experienced cardiopulmonary arrest non‐responsive to cardiopulmonary resuscitation. A postmortem examination was performed, revealing pulmonary haemorrhage, hyaline membrane formation and necrosis. These findings are supportive of a diagnosis of chemical pneumonitis secondary to inhalation of waterproofing shoe spray, resulting in acute respiratory distress syndrome.

AbstractBackgroundAccess to healthcare providers is a key factor in reducing cancer incidence and mortality, underscoring the significance of provider density as a crucial metric of health quality. We sought to characterize the association of provider density on hepatobiliary cancer population‐level incidence and mortality.Study DesignCounty‐level hepatobiliary cancer incidence and mortality data from 2016 to 2020 and provider data from 2016 to 2018 were obtained from the CDC and Area Health Resource File. Multivariable logistic regression was utilized to evaluate the relationship between provider density and hepatobiliary cancer incidence and mortality.ResultsAmong 1359 counties, 851 (62.6%) and 508 (37.4%) counties were categorized as urban and rural, respectively. The median number of providers in any given county was 104 (IQR: 44–306), while provider density was 120.1 (IQR: 86.7–172.2) per 100,000 population; median household income was $51,928 (IQR: $45,050–$61,655). Low provider‐density counties were more likely to have a greater proportion of residents over 65 years of age (52.7% vs. 49.6%) who were uninsured (17.4% vs. 13.2%) versus higher provider‐density counties (p < 0.05). Moreover, all‐stage incidence, late‐stage incidence, and mortality rates were higher in counties with low provider density. On multivariable analysis, moderate, and high provider density were associated with lower odds of all‐stage incidence, late‐stage incidence, and mortality.ConclusionHigher county‐level provider density was associated with lower hepatobiliary cancer‐related incidence and mortality. Efforts to increase access to healthcare providers may improve healthcare equity as well as long‐term cancer outcomes.
