Published: May 2023

AbstractAtmospheric Water Harvesting (AWH) using porous adsorbents is emerging as a promising solution to combat water shortage. Thus, a clearer understanding of the developing trends and optimization strategies of different porous adsorbents can be extremely helpful. Therefore, in this concept, the different types of porous adsorbents and AWH devices are briefly introduced with a focus on the factors that influence the static and kinetic properties of porous adsorbents and their respective optimization strategies. In addition, the fast transport characteristics of water molecules in micropores are studied from the perspective of superfluidity as part of the analysis of the kinetic properties of porous adsorbents. Finally, the future development of porous materials for AWH and the accompanying challenges are summarized.

AbstractA novel boron‐containing hyperbranched benzoxazine (HB‐B) was synthesized from the reaction of triethanolamine borate (BAE), bisphenol‐A, and paraformaldehyde via Mannich condensation. The chemical structures of BAE and HB‐B were characterized by Fourier transform infrared (FT‐IR) and hydrogen nuclear magnetic resonance (1H NMR). Afterward, the boron‐containing hyperbranched benzoxazine/epoxy resin copolymers (E51/HB‐B) were prepared. The curing behavior of ‐B and E51/HB‐B was studied by FT‐IR and differential scanning calorimeter (DSC). The thermal stability and flame retardancy properties of the cured HB‐B and E51/HB‐B were evaluated by thermogravimetric analyzer (TGA), limited oxygen index (LOI), UL94 rating test, and microscale combustibility calorimeter experiments (MCC). The initial thermal decomposition temperature and glass transition temperature steadily dropped with increasing HB‐B content, while the char yield kept rising. The LOI value of the E51/HB‐B‐12 wt% was 31.8%, meeting the UL94 V‐0 specification. The result of heat release capacity (HRC) decreased by 20.4%. Moreover, the mechanical properties were also improved, and the tensile strength of E51/HB‐B copolymer was increased by 88.5%. Finally, the fracture morphology of E51/HB‐B was characterized by SEM.

AbstractIntroductionA nomogram for predicting the diagnosis of lower urinary tract obstruction (LUTO) based on an antenatal ultrasound index generated from a Bayesian Meta‐regression analysis has been in development and noted with superior diagnostic accuracy compared to the keyhole sign (KHS). We aim to assess the accuracy of the nomogram in expanded diagnostic utilization to predict LUTO.MethodologyThe validation of the nomogram for expanded diagnostic utilization was based on data from a prospective institutional antenatal clinic database between January 2020 and June 2022. Diagnostic accuracy indices were determined for confirmed postnatal diagnosis of LUTO or prune belly syndrome (PBS). Receiver operating characteristics (ROC) curves were generated to compare the area under the curve (AUC) of the nomogram versus KHS.ResultsBased on 84 male fetuses with antenatal ultrasound of moderate‐severe hydronephrosis (PUV n = 15, PBS n = 4), the KHS had 26.3% (95%CI 9.1–51.2) sensitivity and 100% (95%CI 94.4%–100%) specificity, with 14 false‐negatives. The nomogram showed a 84.2 (95%CI 60.4%–96.6%) sensitivity and 95.4 (95%CI 87.1%–99%) specificity with three false‐positives. The nomogram also had a superior AUC compared to KHS (0.98 vs. 0.63).ConclusionThe nomogram can be used as a valuable tool to trigger further postnatal screening and provide individualized risk assessments to families during prenatal counseling.

AbstractIn this study, bisphenol A epoxy resin, 1,6‐Hexanediol diacrylate (HDDA), and 2,4,6‐Trimethylbenzoyl‐diphenylphosphine oxide (TPO) were utilized as a prepolymer, diluent, and photoinitiator, respectively, to prepare a light curing system with different amount of phosphor, which was used in place of conventional inorganic fillers. Phosphor was utilized to improve the precision of the material molded parts during the light curing process and enhance the mechanical properties of the molded parts owing to the ultraviolet (UV) absorption properties of phosphor, which prevented UV damage to the material, thus improving the light aging resistance and stability of the molded parts. Results revealed that the addition of 3% phosphor optimized the mechanical properties of the material (a maximum tensile strength of 42.43 MPa). Additionally, the material achieved the lowest linear (4.1%) and volumetric (0.58%) shrinkage at a phosphor content of 6%. This study provides a new insight into three‐dimensional (3D) printing resin for stereolithography and provides a reference for the improvement of 3D printing products.

Published: May 2023

AbstractDespite the availability of several classes of antiemetics, postoperative nausea and vomiting (PONV) remains a substantial burden for patients following surgery, resulting in patient dissatisfaction and prolonged stays in post‐anesthesia care units and ultimately increasing the cost of care. Enhanced recovery protocols and PONV management guidelines are now centered on the assessment of the individual patient's risk for developing PONV, as well as multimodal prophylaxis using antiemetics targeting different mechanisms of action. Over the last two decades, the neurokinin‐1 receptor (NK1R) has emerged as a therapeutic target for the management of PONV. This review of the literature explains the role of the NK1R and its ligand—substance P—in vomiting, describes the pharmacologic and pharmacokinetic properties of NK1R antagonists (NK1RAs) and summarizes the clinical evidence supporting NK1RAs for PONV prophylaxis in patients undergoing surgery. In particular, we discuss the therapeutic application of NK1RA in PONV prophylaxis protocols owing to their advantages over other antiemetic classes in efficacy, duration of efficacy, safety, pharmacology, and ease of administration. Future studies will be aimed at further investigating the efficacy and safety of NK1RA‐based multimodal combinations, particularly among vulnerable populations (e.g., children and elderly).

AbstractA new medium bandgap polymer incorporating electron‐rich 4,8‐bis(5‐(2‐ethylhexyl)thiophen‐2‐yl)benzo[1,2‐b:4,5‐b']dithiophene (BDTT) and electron‐deficient 2,3‐didodecyl‐6,7‐difluoro‐5,8‐di(thiophen‐2‐yl)quinoxaline (2TffQ) units in an alternate manner, namely P(BDTT‐2TffQ), was prepared for organic solar cell (OSC) applications. The optical and electrochemical properties of P(BDTT‐2TffQ) were found to be suitable to use it as an electron donor in OSCs. The absorption band covers the region from 300 to 600 nm with an optical bandgap (Eg) of 1.84 eV, and it highest occupied and lowest unoccupied molecular orbitals (HOMO and LUMO) were found to be positioned at −5.36 and − 3.52 eV. The OSCs prepared by using P(BDTT‐2TffQ):[6,6]‐Phenyl‐C71‐butyric acid methyl ester (PC70BM) and P(BDTT‐2TffQ):2,2′‐((2Z,2'Z)‐((12,13‐bis(2‐ethylhexyl)‐3,9‐diundecyl‐12,13‐dihydro‐[1,2,5]thiadiazolo[3,4‐e]thieno[2″,3″:4′,5′]thieno[2′,3′:4,5]pyrrolo[3,2‐g]thieno[2′,3′:4,5]thieno[3,2‐b]indole‐2,10‐diyl)bis(methanylylidene))bis(5,6‐difluoro‐3‐oxo‐2,3‐dihydro‐1H‐indene‐2,1‐diylidene))dimalononitrile (Y6) blends provided a maximum power conversion efficiency (PCE) of 5.50% and 11.65%, respectively. The differences in the photovoltaic performances of OSCs are mainly attributed to their dissimilar short‐circuit current (Jsc), which depends on their absorption spectrum. Herein, we also compared the properties of P(BDTT‐2TffQ) with a structurally similar polymer, namely P(BDTT‐2TfQ), made up of BDTT and 2,3‐didodecyl‐6‐fluoro‐5,8‐di(thiophen‐2‐yl)quinoxaline (2TfQ) units, for better understanding the effects of the incorporation of additional fluorine atom on the backbone of quinoxaline‐based polymers.

AbstractBackgroundThe precise staging and proper management of high‐risk prostate cancer (PCa) continues to be a challenge. We aimed to demonstrate the prognostic value of baseline prostate‐specific membrane antigen‐ligand positron emission tomography/computed tomography (PSMA‐PET/CT) in high‐risk, nonmetastatic PCa patients who received neoadjuvant hormonal or chemohormonal treatment followed by radical prostatectomy (RP).MethodsWe performed retrospective analyses of 70 patients with high‐risk, nonmetastatic PCa confirmed by biopsy between 2018 and 2021. All patients underwent neoadjuvant therapy followed by RP and pelvic lymph node dissection (PLND); PSMA‐PET/CT was performed before initiation of neoadjuvant therapy. Acquired image information and clinical characteristics/outcomes were examined for possible associations.ResultsAmong 70 high‐risk PCa patients, median age was 69 years old and median prostate specific antigen (PSA) at presentation was 58.5 ng/mL. Thirty (42.9%) patients had uptake of the PSMA tracer only in the primary PCa lesions and 40 (57.1%) patients had PSMA‐positive lesions in regional or distant sites. Sixteen (32%) localized PCa patients defined by pre‐PET magnetic resonance imaging were found to have locally advanced PCa based on PSMA‐PET/CT. Fifteen (30%) localized PCa patients and 7 (35%) locally advanced PCa patients were upstaged to metastatic PCa. The sensitivity and specificity of PSMA‑PET/CT for the detection of lymph node involvement were 90.9% and 69.5%, respectively, with a positive prediction value of 35.7% and negative prediction value of 97.6%. The diagnostic accuracy was 72.9%. Univariate analysis showed upstaging, tumor stage, and metastasis location based on PSMA‑PET/CT are predictors to PSA persistence after surgery, while multivariate logistic regression analysis showed only the tumor stage based on PSMA‐PET/CT remained an independent predictor of the outcome.ConclusionsThis study further highlights the accuracy and necessity of PSMA‐PET/CT in newly diagnosed, high‐risk, nonmetastatic PCa patients.
“Don't Say Gay”: The influence of state political factors
Authors: Davis Nickolas B. 
Published: May 2023

AbstractRecently, several states have introduced legislation designed to limit discussion around sexual orientation and gender identification. These types of legislation have been widely referred to as “Don't Say Gay” bills. Three state political characteristics: political culture, interparty competition, and general policy liberalism, which are deeply rooted in the political science literature, were used to examine a state's tendency to introduce or pass “Don't Say Gay” legislation. By using these variables, the state was not viewed in the Democratic/Republican dichotomy but rather by aspects enshrined in the state's political system. Using correlation analysis, the results from this study show that all three state political variables are correlated with introducing or passing a “Don't Say Gay” bill, while binary logistic regression results show that only political culture and interparty competition are statistically significant predictors of a state introducing or passing a “Don't Say Gay” bill.

AbstractA series of paraffin@poly(methyl methacrylate) phase‐change microcapsules (Pn@PMMA) were synthesized by suspension polymerization. The prepared Pn@PMMA had excellent latent heat storage and release properties (ΔHm=183.2 J/g, ΔHc=181.9 J/g), excellent thermal stability and cycle durability of at least 100 cycles. The effects of emulsifier type, cross‐linking agent content and core/shell mass ratio on structure and properties of Pn@PMMA were investigated by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT‐IR) and differential scanning calorimetry (DSC). The morphology of Pn@PMMA exhibited spherical profile with styrene‐maleic anhydride (SMA) as emulsifier and the agglomeration was significantly reduced. The enthalpy of the microcapsules was significantly improved with the addition of crosslinker. The anti‐permeability of Pn@PMMA subsequently further improved with continued increasing amount of cross‐linker. Besides, the enthalpy and anti‐leaking property of the microcapsules progressively reduced with the core/shell mass ratio decreased, while the thermal conductivity gradually increased. Therefore, the results showed that the Pn@PMMA with the enthalpy of 183.2 J/g and the leakage rate of 4.72 %, which displayed a high thermal reliability potential for thermal energy storage and temperature regulation.

AbstractThe development of low‐cost ammonia sensors with high sensitivity and selectivity has gained considerable interest. Though the response of these sensors at room temperature is low and needs enhancement. In the present study high sensitivity ammonia gas sensors based on nanocomposite films of polyaniline (PANI) and with varying ZnO concentrations were synthesized and investigated. With a loading of 10 at% ZnO, the gas sensing response of 59 % was obtained for 120 ppm NH3 gas. The gas response was further enhanced by decorating the ZnO nanorods with different concentrations of silver (Ag) nanoparticles. The Ag‐decorated ZnO nanorods were embedded in the PANi matrix using the in‐situ oxidative polymerization technique. It was shown that PANi ZnO, p‐n junction, and the introduction of porosity in nanocomposite act synergistically in increasing the resistance caused by the deprotonation of PANi by NH3. Among various compositions studied, 2 % loading of Ag in ZnO embedded in PANi matrix, thin films were found to be highly selective and sensitive towards NH3 gas at room temperature with a chemiresistive response of 70 % at 120 ppm and a recovery time of less than 120 s. The selectivity of the nanocomposite was also studied towards various reducing and oxidizing gasses.

AbstractA solid‐state method was used to derive a sulfur rich CuO‐carbon nitride core‐shell nano‐composite from a Cu‐organic hybrid. The synthesized material was characterized by XRD, morphology by SEM and TEM. Elemental analysis was investigated using EDS. The novel sulfur rich CuO‐carbon nitride core‐shell composite demonstrated as peroxidase activity for the oxidation of aminophenol isomers in the presence of H2O2. The oxidized products of o‐aminophenol (o‐AP) and p‐aminophenol (p‐AP) in phosphate buffer (PB, pH 7) showed strong absorption peaks at 435 and 475 nm, respectively in the UV‐Visible spectra. Whereas no oxidation reaction was observed for m‐aminophenol. Kinetic analysis of sulfur rich CuO‐graphitic carbon nitride revealed that the catalyst functioned by a ping‐pong mechanism for the oxidation of both o‐AP & p‐AP by hydrogen peroxide (H2O2). Based on KM values, substrate affinities were in the order o‐AP>H2O2>p‐AP. We further used this material for selective colorimetric detection of o‐AP and p‐AP in PB pH 7. The linear ranges obtained for o‐AP and p‐AP were 1–200 μM (LOD=1.5 μM, r2=0.99) and 10–500 μM (LOD=2.27 μM, r2=0.99), respectively. The developed analytical platform was used to detect these isomers in river water and p‐AP in artificial urine.

AbstractA BF3 ⋅ CH3CN‐promoted synthesis of aryl α‐O‐glycosides from readily available glycosyl donors was developed. This reaction could proceed well on a gram‐scale under mild condition with α/β ratio up to 95 : 5. Moreover, a variety of the glycosyl donors including acetylated/benzoylated pyranoses, di‐ and trisaccharide derivatives as well as glycosyl acceptors from substituted phenols, sterically hindered aliphatic alcohols and carboxylic acid, were well tolerant. Importantly, the potential of this strategy was highlighted with a successful gram‐scale synthesis of oligosaccharide EPS‐G7, which is a commercial detection reagent for quantitative determination of α‐amylase.

AbstractThe recovery of critical metals from spent lithium‐ion batteries (LIBs) is important to sustainable development and environment protection. In this paper, sec‐octylphenoxyacetic acid (CA‐12) was first used to recover valuable metals in LIBs. The effects of phase modifier, initial feed pH, extraction kinetics and thermodynamics, CA‐12 concentration and saponification degree were studied and optimized. Under the optimal conditions, 99 % of nickel, cobalt and manganese were co‐extracted to the organic phase, and the loss of lithium was 7 %. The extracted metal ions could be stripped with 0.04 mol/L HCl equivalently. In the spent LIBs powder leaching experiment, leaching efficiencies of all components were greater than 95 %. In the impurity removal stage, extractant N902 was used to remove copper, while iron and aluminum were eliminated by hydrolysis. After two‐stage extraction, the total extraction efficiencies of nickel, cobalt and manganese reached 99.7 %, 99.4 %, 98.45 %, respectively. Finally, lithium in the raffinate was precipitated by saturated Na2CO3, the purity of recovered Li2CO3 was up to 97.7 %. After 5 times cycles, CA‐12 still maintained excellent extraction capacity, showing its potential application prospects for recovering critical metals form spent LIBs.

AbstractNatural amino acids are the most important building blocks in supramolecular chemistry which possess the best biocompatibility in nature. To the best of our knowledge, although hydrogels based on amino acid derivatives have already been studied widely, there is still no report about natural amino acids hydrogels constructed by metal ions induction method. Herein, the self‐assembly behaviors of twelve natural amino acids with eight metal ions were studied systematically. It is surprising that only sodium L‐Phenylalanine can self‐assemble into hydrogel with ZnCl2. Various methods were used to investigate the formation mechanism of hydrogel. The formation of hydrogel is triggered mainly via π‐π stacking and metal‐ligand interactions. Moreover, this green L‐Phenylalanine hydrogel displays acid responsiveness and relatively stability under high temperature, which has great potential applications in many fields.

AbstractHerpes simplex virus type 1 (HSV‐1) is a human pathogen that causes recurrent infections. Acyclovir‐resistant strains exist and can cause severe complications, which are potentially untreatable with current therapies. We have developed siRNA swarms that target a 653 base pair long region of the essential HSV gene UL29. As per our previous results, the anti‐UL29 siRNA swarm effectively inhibits the replication of circulating HSV strains and acyclovir‐resistant HSV strains in vitro, while displaying a good safety profile. We investigated a single intranasal therapeutic dose of a siRNA swarm in mice, which were first inoculated intranasally with HSV‐1 and given treatment 4 h later. We utilized a luciferase‐expressing HSV‐1 strain, which enabled daily follow‐up of infection with in vivo imaging. Our results show that a single dose of a UL29‐targeted siRNA swarm can inhibit the replication of HSV‐1 in orofacial tissue, which was reflected in ex vivo HSV titers and HSV DNA copy numbers as well as by a decrease in a luciferase‐derived signal. Furthermore, the treatment had a tendency to protect mice from severe clinical symptoms and delay the onset of the symptoms. These results support the development of antiviral siRNA swarms as a novel treatment for HSV‐1 infections.
