It was hypothesized that symptom screening and provision of symptom reports to the health care team would reduce symptom burden in pediatric patients with cancer.ObjectiveTo determine if daily symptom screening and provision of symptom reports to the health care team was associated with lower total symptom burden as measured by the Symptom Screening in Pediatrics Tool (SSPedi) compared to usual care among pediatric patients with cancer admitted to a hospital or seen in a clinic daily for at least 5 days.Design, Setting, and ParticipantsThis randomized clinical trial enrolled participants from July 2018 to September 2023 from 8 Canadian tertiary care centers that diagnose and treat pediatric patients with cancer. Patients aged 8 to 18 years with cancer expected to be in a hospital or clinic daily for at least 5 consecutive days were eligible for inclusion. Participants were randomized to intervention (n = 176) vs control (n = 169) groups. Data were analyzed from November 2023 to December 2023.InterventionIntervention participants completed the SSPedi once daily for 5 days. Printed symptom reports were provided daily to the health care team, and email alerts were distributed for severely bothersome symptoms. Control participants received usual care.Main Outcomes and MeasuresThe primary outcome was self-reported total SSPedi score on day 5. Secondary outcomes were individual SSPedi symptoms, pain, quality of life, symptom documentation, and intervention provision. The primary analysis compared the day 5 total SSPedi scores between randomized groups using a multiple linear regression model. For the secondary analysis comparing individual SSPedi symptom scores, the odds ratio for the intervention was estimated using a proportional odds model. Pain and quality of life were analyzed using the same approach as the primary outcome. Fisher exact test was used to compare symptom documentation, any intervention, and symptom-specific intervention between groups.ResultsA total of 345 participants were enrolled; median (range) participant age was 13.8 (8.0-18.8) years, and 150 participants (43.5%) were female. Day 5 SSPedi score was significantly better with symptom screening compared to usual care (adjusted mean difference, −2.5; 95% CI, −3.8 to −1.2). Symptom screening reduced the odds of higher individual symptom scores; 8 of 15 symptom reductions were statistically significant. There were no significant differences in pain or quality of life scores between groups. Five symptoms were documented or treated significantly more often with symptom screening than usual care.Conclusions and RelevanceIn this randomized clinical trial, among pediatric patients with cancer admitted to a hospital or seen in a clinic daily for at least 5 days, symptom screening with SSPedi improved total symptom scores compared to usual care.Trial RegistrationClinicalTrials.gov Identifier:","PeriodicalId":24,"journal":{"name":"ACS Sensors","volume":"49 1","pages":""},"PeriodicalIF":26.1,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142610067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the high-temperature crystallization process (≈340 or 180 °C) limits their further development, especially in flexible PSCs. Here, a Cs─I bond weakening approach is proposed to realize the low-temperature crystallization of CsPbI₃ by introducing organic sulfonate of 1-propylsulfonate-3-methylimidazolium chloride (SMCl). SMCl can strongly interact with CsI and weaken the Cs─I bond to dissociate free I⁻ ions for the effective transition of initial PbI₂ to [PbI₆]⁴⁻, which greatly decreases the crystallization temperature of black CsPbI₃ to 90 °C. As a result, flexible PSCs are realized with efficiency of 13.86%, which is the highest efficiency of flexible CsPbI₃ devices. Besides, SMCl will also help to release the tensile strain and stabilize CsPbI₃ phase, leading to good thermal and mechanical stability. Almost no efficiency loss is observed in flexible PSCs after 36000 bending cycles with a curvature radius of 5 mm.","PeriodicalId":24,"journal":{"name":"ACS Sensors","volume":"25 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the chemical structure and role of its functional groups have not been thoroughly elucidated. This study introduces a novel modification of BCP in perovskite solar cells (PSCs) by altering functional groups to optimize their geometrical molecular structures and electronic properties. The substitution of aromatic phenyl and p-tolyl groups to 2,9-position on the BCP is highly effective in increasing the planarity of the conjugated backbone and protecting the reactive nitrogen atoms of the phenanthroline core, thereby improving charge transport and device stability. Experimental analyses, including electrostatic force microscopy, impedance spectroscopy, and photoluminescence, reveal that the modified BCP significantly enhances charge transport, reduces recombination losses, and markedly improves the structural stability of PSCs, leading to prolonged device lifetimes. The findings highlight the potential of structurally optimized BCP derivatives as a critical component in advancing high-efficiency and durable PSCs.","PeriodicalId":24,"journal":{"name":"ACS Sensors","volume":"40 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it remains unclear how the I/C ratio affects Fe-N-C degradation and the stability of single Fe atom active sites (FeN_x). Here, an accelerated stress test (AST) protocol is combined with emerging electrochemical techniques for a porous Fe-N-C in PEMFC with a range of I/C ratios. The PEMFC current density degradation rates are found to be comparable; however, with increased I/C ratio the additional FeN_x sites accessed are more stable, as shown by their higher active site stability number (electrons passed per FeN_x lost) at the end of the AST protocol. Meanwhile, the initial rate of TOF decay is suppressed with increasing I/C. Electrochemical process changes are studied via distribution of relaxation times analysis. Minor changes in H⁺ and O₂ transport resistance at low current density prove kinetic degradation dominants at high potentials. These findings demonstrate how electrochemical techniques can be combined with stability metrics to determine and deconvolute changes from the active site to device level electrochemical processes in PEMFCs.","PeriodicalId":24,"journal":{"name":"ACS Sensors","volume":"6 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, massive challenges such as poor ionic migration ability, low antioxidant ability, and lithium dendrite formation still remain unresolved. These issues severely restrict its practical applications. Herein, a new type of solid-state polymer electrolyte with a molecular crowding feature is rationally designed by in situ polymerization of a precursor containing poly (ethylene glycol) diacrylate (PEGDA) and 1,2-dimethoxyethane (DME). Noticeably, the prepared SPE expands the electrochemical window to 4.7 V with a high lithium-ion transfer number of 0.55 and a superior ionic conductivity of 3.6 mS cm⁻¹ at room temperature. As a result, the lithium symmetrical batteries achieve stable cycles with more than 3000 h with no lithium dendrites at a current density of 0.5 mA cm⁻². Importantly, this design provides dense contact of solid-state polymer electrolytes with the porous cathode and lithium anode, allowing the assembled winding-type solid-state pouch cells with outstanding cycling stability of 81.7% retention for more than 340 cycles at room temperature. It shows excellent adaption to widely practical technology with large-scale battery production, offering a new solution for the future development of solid-state polymer lithium-metal batteries.","PeriodicalId":24,"journal":{"name":"ACS Sensors","volume":"17 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, as the bottom low-bandgap subcells, tin-lead (Sn-Pb) perovskites suffer from severe nonradiative recombination at the interfaces due to their susceptibility to oxidation and poor crystalline morphology. Here a surface modifier 4-(trifluoromethyl)benzhydrazide (TFH) is reported to construct a reductive chemical environment on the surface of perovskite films and protect them from water and oxygen erosion. TFH anchors onto the Sn-Pb perovskites in a preferred vertical orientation through dual-site binding, forming interface dipoles that facilitate charge extraction. The reductive hydrazine groups of TFH can effectively inhibit the oxidation of Sn²⁺ and I⁻, thereby reducing the defect density and energy disorder of Sn─Pb perovskites. Consequently, the TFH-treated devices achieved a champion PCE of 22.88%, maintaining over 93% of the initial efficiency after continuous one-sun illumination for 500 h.

The substitution of the sulfur atom on the outer ring of the fused‐ring core of DC9‐HD with a selenium atom resultes in the red‐shifted DYSe‐3. Despite these minor differences, DC9‐HD and DYSe‐3 possess nearly identical conjugated skeletons, which contribute to their similar packing motifs and crystallinities, ultimately enabling a high degree of miscibility between two DMAs. Upon incorporating DYSe‐3 into the host PM6:DC9‐HD binary blend, fibril‐like morphologies featured with diameters of ≈16.9 nm and reduced charge recombination are observed in the PM6:DC9‐HD:DYSe‐3 ternary blend. More importantly, owing to their long exciton diffusion lengths and low voltage losses, a remarkable power conversion efficiency of 19.4% is achieved for the ternary OSCs, alongside a delicate balance between open‐circuit voltage and short‐circuit current density. This super result is comparable to the best performance of oligomer acceptor based OSCs reported to date.

Herein, the Cu single atom anchored polymeric carbon nitride (Cu@PCN) is synthesized by a facile thermal polymerization method. Serving as multifunctional protective layer on Zn surface, the Cu@PCN can provide massive nucleation sites at a nano-level and uniformize the electron distribution through coordination engineering. Optimizing the coordination structures of single Cu and N atoms within the carbon matrix enables a redistribution for electric field and regulates ion flux. More importantly, this coordination strategy with single atoms is first reported to customize oriented and continuous phase epitaxy along highly dendrite-resistant Zn(101) plane by reducing (101) surface energy. This pattern of oriented dense deposition leads to stable and reversible Zn plating/stripping is achieved, which delivers an extended cycling life of 550 h at 10 A cm⁻², 20 mAh cm⁻².

Here, a novel p–n heterojunction strategy is suggested that generates active sites on the basal plane of 2D NiFe‐layered double hydroxide (NiFe‐LDH). The n‐type NiFe‐LDH is first grown on a nickel foam (NF) substrate, and p‐type Co<jats:sub>3</jats:sub>O<jats:sub>4</jats:sub> nanocubes are deposited through a simple dip‐coating method to fabricate a Co<jats:sub>3</jats:sub>O<jats:sub>4</jats:sub>/NiFe‐LDH@NF p–n heterojunction electrode.
