AbstractThe global climate change negatively affects the photovoltaic performance of traditional solar cell technologies. This article investigates the potential of organic photovoltaics (OPV) for high‐temperature environments, ranging from urban hot summers (30—40 °C) and desert regions (65 °C) up to (aero) space conditions (130 °C), the thermal window in which OPV can operate. The approach is based on a combination of experiments and simulations up to 180 °C, moving significantly beyond the conventional temperature ranges reported in the literature. New 2H‐benzo[d][1,2,3]triazole‐5,6‐dicarboxylic imide‐based copolymers with decomposition onset temperatures above 340 °C are used for this study, in combination with non‐fullerene acceptors. Contrary to their inorganic counterparts, OPV devices show a positive temperature coefficient up to ≈90 °C. At temperatures of 150 °C, they are still operational, retaining their room temperature efficiency. Complementary simulations are performed using an in‐house developed software package that numerically solves the drift‐diffusion equations to understand the general trends in the obtained current–voltage characteristics and the materials’ intrinsic behavior as a function of temperature. The presented methodology of combined high‐temperature experiments and simulations can be further applied to investigate the thermal window of operation for other OPV material systems, opening novel high‐temperature application routes.
Disorder‐Controlled Efficient Doping of Conjugated Polymers for High‐Performance Organic Thermoelectrics

Published: October 2023

AbstractMolecular doping of conjugated polymers (CPs) is critical to improve their electrical properties in organic thermoelectric materials, which are promising candidates for low‐temperature energy harvesting and self‐powered sensors. Because excessive dopants are used in the doping process, securing highly crystalline CPs by suppressing dopant‐induced disorder is crucial. Recently, tris(pentafluorophenyl)borane (BCF) has attracted interest as a strong Brønsted acid dopant that enables efficient integer charge transfer by forming a complex with water. However, the crystalline ordering of BCF‐doped CPs has not been properly controlled; the resultant thermoelectric performance is therefore still lower than other p‐doped CPs prepared by conventional redox doping. Here, an efficient doping strategy is proposed with BCF to attain highly doped CPs with dramatically suppressed structural and energetic disorder. In a non‐polar aliphatic solvent, hexane, BCF can effectively diffuse into poly[2,5‐bis(3‐tetradecylthiophen‐2‐yl)thieno[3,2‐b]thiophene] (PBTTT) via sequential doping, leading to remarkable electrical conductivity and power factor of 230 S cm−1 and 140 µW m−1 K−2, respectively. In addition, sequentially doped films exhibit highly delocalized transport characteristics owing to the low degree of charge carrier localization within their high solid‐state ordering. The results provide an approach for disorder‐tolerant doping strategies with a systematic investigation of structure–property relationships in highly doped CPs.

Published: October 2023

AbstractThe interactions with touchscreens rely heavily on vision: The virtual buttons and virtual sliders on a touchscreen provide no mechanical sense of the object they seek to represent. This work presents PopTouch: a 500 µm thick flexible haptic display that creates pressable physical buttons on demand. PopTouch can be mounted directly on touchscreens or any other smooth surface, flat, or curved. The buttons of PopTouch are independently controlled hydraulically amplified electrostatic zipping taxels (tactile pixels) that generate 1.5 mm of out of plane displacement. When pressed by the user, the buttons provide intuitive mechanical feedback thanks to a snap‐through characteristic in their force‐displacement profile. The snap‐through threshold can be as high as 4 N, and is tuned by design and actuation parameters. This work presents two versions of PopTouch: a transparent PopTouch for integration on Touchscreens with built‐in touch sensing, such as smartphones and a sensorized PopTouch, with embedded thin‐film piezoelectric sensors on each taxel, for integration on substrates without built‐in touch sensing, such as a steering wheel. PopTouch adds static and vibrating button‐like haptics to any device thanks to its thin profile, flexibility, low power consumption (6 mW per button), rapid refresh rate (2 Hz), and freely configured array format.

AbstractIn the domains of wearable electronics, robotics, and the Internet of Things, there is a demand for devices with low power consumption and the capability of multiplex sensing, memory, and learning. Triboelectric nanogenerators (TENGs) offer remarkable versatility in this regard, particularly when integrated with synaptic transistors that mimic biological synapses. However, conventional TENGs, generating only two spikes per cycle, have limitations when used in synaptic devices requiring repetitive high‐frequency gating signals to perform various synaptic plasticity functions. Herein, a multi‐layered micropatterned TENG (M‐TENG) consisting of a polydimethylsiloxane (PDMS) film and a composite film that includes 1H,1H,2H,2H‐perfluorooctyltrichlorosilane/BaTiO3/PDMS are proposed. The M‐TENG generates multiple spikes from a single touch by utilizing separate triboelectric charges at the multiple friction layers, along with a contact/separation delay achieved by distinct spacers between layers. This configuration allows the maximum triboelectric output charge of M‐TENG to reach up to 7.52 nC, compared to 3.69 nC for a single‐layered TENG. Furthermore, by integrating M‐TENGs with an organic electrochemical transistor, the spike number multiplication property of M‐TENGs is leveraged to demonstrate an artificial synaptic device with low energy consumption. As a proof‐of‐concept application, a robotic hand is operated through continuous memory training under repeated stimulations, successfully emulating long‐term plasticity.

Published: October 2023

AbstractArticle 12 of the United Nations Convention on the Rights of Persons with Disabilities has been instrumental in driving the development of the concept and practice of supported decision making. An important feature has been the development of “supported decision making pilots.” This paper identifies, describes and analyses pilot programmes providing support for decision making for people with cognitive disabilities in Australia and internationally between 2016 and 2021. It finds that challenges included providing support for socially isolated people and adequately resourcing those programmes. However, most pilots reported positive outcomes for decision makers, adding to the evidence base for claims to be made about the positive impact of supported decision making on the lives of people with disabilities. The pilots demonstrate that, internationally, there is an emerging set of programmes that seek to promote supported decision making incrementally through developing focussed community awareness and practice. While still small‐scale, time‐limited and experimental, with different levels of rigour in practice and evaluation, they provide some foundation and a preliminary evidence base for larger interventions and reforms in the future.

AbstractThe new drug linagliptin belongs to the class of dipeptidyl peptidase‐4 enzyme inhibitors. Linagliptin is used to treat type 2 diabetes and is taken orally either alone or in combination with other drugs. In this instance, a new, simple, and economical technique for analyzing linagliptin was developed by the effective use of a pyrrolidone derivative. The primary amine group of linagliptin permits its condensation with ninhydrin (0.14% w/v) to produce a fluorescent product in the presence of phenylacetaldehyde (0.02% v/v). All experimental parameters were carefully examined and adjusted in order to monitor the generation of the pyrrolidone derivative at excitation and emission wavelengths of 385 and 475 nm, respectively. The calibration graph was made by plotting the intensity of the fluorescence in relation to linagliptin concentration. A significant linearity was found for values ranging from 20 to 460 ng/mL. The process's validity has been verified by a thorough assessment of the instructions provided by the International Conference on Harmonization (ICH). The results indicate excellent uniformity with a reference method, showing that there is no substantial difference in precision and accuracy. The proposed approach was utilized for determining linagliptin in real rat plasma successfully owing to its high sensitivity. Additionally, the proposed approach was evaluated using the Eco‐Scale evaluation tool and showed a high degree of eco‐friendliness (86/100).
Mitral valve‐in‐valve with 4D intracardiac echocardiography: Procedural and imaging technique
Authors: Wong Ningyan , Fowler Dale , Lim D. Scott 
Published: October 2023

AbstractTranscatheter mitral valve‐in‐valve (ViV) has emerged as a safe and effective therapeutic option for patients with a degenerated mitral bioprosthesis. As procedural techniques mature and operator experience improve, there is a push to adopt a “minimalist” approach of using conscious sedation instead of general anesthesia for faster recovery. The heavy reliance on fluoroscopy for ViV deployment makes feasible the use of intracardiac echocardiography (ICE) instead of transesophageal echocardiography for other procedural imaging requirements. We hereby use a case example to illustrate a step‐by‐step approach of using four‐dimensional ICE to guide transcatheter mitral ViV under conscious sedation.

AbstractBackgroundThis study aimed to assess the safety and effectiveness of a novel technique for catheter ablation in patients with premature ventricular contraction (PVC) from the free wall of tricuspid annulus (TV).HypothesisWe hypothesized that the novel technique is more efficacious than the traditional approach.MethodsWe retrospectively investigated 59 consecutive patients with PVC originating from the free wall of TV between January 2013 and November 2021. The patients were divided into two groups: the reversed S‐curve technique group (RST, n = 26) and the reversed C‐curve technique group (RCT, n = 33). The RST under the support of a steerable sheath was used in RST group, while the RCT under the support of a nonsteerable sheath was used in the RCT group. Systematic mapping and radiofrequency ablation were preferentially performed under the valve in all patients.ResultsCompared to the RCT group, total procedural time and fluoroscopic exposure time were significantly shorter in RST group. Two patients experienced cardiac tamponade in the RCT group, while no complications were observed in RST group (p = .498). The success rate was significantly higher in RST group compared to RCT group (81.9% vs. 100%, p = .029). Three patients in RCT group failed to ablate during the operation but were successfully ablated using the novel method. During regular follow‐up, no patients in the RST group had a recurrence, while three patients in the RCT group did (p = .274).ConclusionsIt suggests that the reserved S‐curve technique, supported by a steerable sheath, is a feasible and effective method for ablating PVC originating from the free wall of TV.

Authors: Aluchna Maria , Roszkowska‐Menkes Maria , Khan Sana 
Published: October 2023

AbstractThe last three decades have witnessed substantial growth in the literature exploring the motives and drivers of corporate greening. Extant research analyzing the governance determinants of corporate environmental disclosure provides competing and contrasting results; despite the growing sustainability challenges create an urgent need for effective monitoring and incentive mechanisms to promote corporate transparency and accountability. This warrants further inquiry in the field, yet very few comprehensive reviews have been presented on governance determinants of corporate environmental disclosure. To fill this gap we conduct a systematic review of 121 published papers and distinguish the governance mechanisms fostering corporate environmental disclosure. Our paper identifies factors influencing the adoption, extant, and quality of environmental disclosure, and provides useful future research directions.
Effect of a V‐shaped canyon on the seismic response of a bridge under oblique incident SH waves

Published: October 2023

AbstractTo elucidate the effect of canyon topography on dynamic response of a bridge, an analytical model for a simply supported bridge crossing a symmetric or non‐symmetric V‐shaped canyon in an elastic half‐space under SH waves is proposed. An exact solution to the dynamic canyon‐bridge interaction problem is derived using wave function expansion and verified by its comparison with past exact solution for a sole bridge model without a canyon. The wave propagation in the half‐space, wave scattering by the canyon and wave radiation from the bridge are all taken into account rigorously. Through a systematical parametrical study, it is found that the seismic response of the bridge beam and the wave‐facing side foundation will be significantly amplified. The degree of the topographic amplification is closely related to the geometry of the canyon, the mass and the stiffness of the bridge beam, and the frequency content and angle of the incident wave. The potential adverse effects of a V‐shaped canyon on a bridge should be considered in its seismic design.

Published: October 2023

AbstractBackgroundThe lack of sophisticated diagnosing equipment for polymerase chain reaction (PCR) during the incidence of variant types of COVID‐19 underestimates the morbidity and mortality patterns of this pandemic. Thus, this study aimed to estimate seropositive and confirmatory predictors for COVID‐19 suspected and tested cases through polymerase chain reaction (RT‐PCR) in two diagnosingMethodsA facility‐based descriptive cross‐sectional study was employed among COVID‐19 suspected cases from January 2, 2022, to June 9, 2022. The data were collected both using a structured interviewees and nasopharyngeal (NP) swabs. The nasal swab (NS) was analyzed in the laboratory for RNA detection of the virus using PCR. The collected data were entered into Epi Data version 4.2 and then exported to STATA (SE) version R‐14 software for further analysis. multivariable logistic regression was used to assess the associated riskResultsA total of 285 suspected cases have participated in this study. The overall mean (±SD) age of the participants was 37.5 (±18.5) years. The majority, 174 (61.1%) of the tested groups were symptomatic when diagnosed. The positivity of RT‐PCR for suspected and COVID‐19 diagnosed cases were confirmed in 62/285 (21.75%). In multivariable analysis, they were aged 26–50 years (adjusted odds ratio [AOR] = 4.2, 95% confidence interval [CI] = 1.5–10.75), had comorbidity (AOR = 5.8; 95% CI = 2.1–12.2), and cigarette smokers (AOR = 13.5; 95% CI = 5.3–36.6) were significantly associated with developing COVID‐19 infection.ConclusionMore than two in every nine suspected cases were positive RT‐PCR tests, and the infectivity of COVID‐19 was significantly associated with age 25–50 years, comorbidities, and cigarette smoking. The deployment of high‐quality diagnostic kits like RT‐PCR is crucial for the early detection and risk stratification of suspected cases.
Introducing a stratified vertical gravel tube subsurface drip system under different irrigation regimes for pistachio: Growth, yield and water productivity

Published: October 2023

AbstractHigh evapotranspiration and low precipitation are known as the main challenging factors for pistachio (Pistacia vera L.) orchards situated in arid and semi‐arid regions. Therefore, it is necessary to take some measures to mitigate surface evaporation. This study was carried out to assess water productivity (WP) as well as yield and annual shoot growth of pistachios using a new method of irrigation known as the stratified vertical gravel tube subsurface drip irrigation (SVGTSD) system in a 15‐year‐old pistachio orchard in an arid region in Iran. In this system, each tree contained four vertical gravel columns with different lengths. A randomized complete block design with a split‐plot arrangement with three replicates (five trees in each plot) for 3 years was used. Three irrigation regimes included 100% crop evapotranspiration (100% ETc), 85% ETc and 70% ETc (as the main plots), and seven vertical gravel column with a depth arrangement of 40–40–40–40 cm (using a gravel column from the lateral pipe level and without a gravel tube as the control) and gravel‐filled tubes with depths of 10–10–10–10 cm, 10–10–20–20 cm, 10–10–30–30 cm, 10–10–20–30 cm, 10–10–20–40 cm and 10–10–20–50 cm (all 30 cm below ground level) (as subplots) were used. The results showed that the different depths of gravel tube placement significantly affected the annual shoot growth and yield. The deeper the tube was placed, the greater the yield and annual shoot growth, resulting in 10–10–20–50 cm being the most productive. Regarding tree growth, yield and WP, the best performance was observed at full irrigation (100% ETc) with a 10–10–20–50‐cm vertical gravel tube arrangement. Furthermore, in this subsurface irrigation method, there was no concern regarding emitter clogging by roots, root accumulation around the emitters or root intrusion into the emitters. In addition, having a low additional cost (only 13.9%) in comparison with conventional subsurface drip irrigation together with a higher yield (3475 kg ha−1), WP (0.9 kg m−3) and shoot growth (35 cm), SVGTSD is more economical and feasible compared to other irrigation methods and can be extensively applied in pistachio orchards.

Published: October 2023

Study Objective. To evaluate the effects of ω‐3 fatty acids on blood pressure control and lipid levels.Design. Double‐blind, placebo‐controlled, randomized study.Setting. Veterans Affairs Medical Center teaching hospital.Patients. Twenty‐one men whose blood pressure was not optimally controlled with antihypertensive agents, who met the inclusion criteria.Interventions. Patients were randomized to receive either fish oil (4.5 g ω‐3 fatty acids/day) or placebo.Measurements and Main Results. Blood pressure readings were taken at baseline, and 4 and 8 weeks. Sitting systolic and diastolic blood pressures were significantly reduced in the fish oil group at both week 4 (148/97 to 132/90, p<0.05) and week 8 (148/97 to 134/91, p<0.05). Sitting diastolic blood pressure was significantly reduced in the placebo group at week 8 (94 to 88, p<0.05). There was no difference in percentage change of sitting systolic and diastolic pressures at week 8 comparing the placebo group (−6.4% and −6.3%, respectively) and the fish oil group (−8.8% and −6.6%, respectively). Triglyceride levels (−40.9%, p<0.05) and platelet counts (−8.7%, p<0.05) were significantly reduced at 4 weeks, and low‐density lipoprotein (LDL) cholesterol levels were significantly increased both at 4 and 8 weeks (13.5% and 19.1%, respectively) in the fish oil group.Conclusion. Adjunctive fish oil supplementation did not substantially augment blood pressure lowering in treated hypertensive men with suboptimally controlled blood pressure. Effects on plasma lipid values were mixed, with an increase in LDL cholesterol and a decrease in plasma triglyceride levels.

Published: October 2023

Study Objective. To determine if one commercial extended‐release formulation of nifedipine (Adalat CC) is as effective as another (Procardia XL) in controlling blood pressure over 24 hours.Design. Open‐label, randomized, crossover study.Setting. University‐affiliated family medicine clinic.Patients. Fifteen patients with stage 1–4 primary hypertension.Interventions. Procardia XL or Adalat CC once/day was titrated to achieve blood pressure control. The effective dose was continued for 4 weeks, washed out for 1 week, and reinstituted with other study drug.Measurements and Main Results. Twenty‐four‐hour ambulatory blood pressure was recorded the conclusion of each treatment phase. Treatment phases were compared for mean 24‐hour blood pressure, mean daytime (6:00 a.m.–10:00 p.m.) and mean nighttime blood pressure, and mean blood pressure load (percentage of blood pressure measurements < 140/90 mm Hg daytime and > 120/80 mm Hg nighttime). Thirteen patients completed the study. No statistically significant difference was seen in mean 24‐hour blood pressure (138/86 mm Hg for Procardia XL vs 137/85 mm Hg for Adalat CC), daytime or nighttime blood pressure, or blood pressure load. Two patients experienced clinically significant adverse effects while taking Adalat CC.Conclusions. In these patients with primary hypertension, Adalat CC was as effective as Procardia XL at controlling blood pressure for 24 hours. Blood pressure, heart rate, and adverse effects should be monitored 2–4 weeks after any exchange of Adalat CC for Procardia XL.
