The solar‐driven interfacial evaporation system has attracted much attention in recent years due to its reduced heat loss and accelerated steam generation. As a low‐cost and readily available resource, wood is widely applied as photothermal materials in solar‐driven interfacial evaporation system because of its superior water transfer and heat loss prevention properties. Herein, a simple, mild, and cost‐effective method is employed to fabricate wood‐based photothermal materials. The results demonstrate that the solar absorption rate of wood‐nigrosine is more than 97.5% across a wide wavelength range (200–2500 nm), and an evaporation rate of 1.46 kg m−2 h−1 and evaporation efficiency (86.1%) are achieved under 1‐sun illumination (100 mW cm−2). The solar‐driven interfacial evaporation system based on wood‐nigrosine exhibits strong structural stability and processing capability for dyes and seawater. [ABSTRACT FROM AUTHOR]

Abstract: Ba(Zr x Ti1−x )O3 (BZT) (x =0.20 and 0.30) thin films are deposited on Pt(111)/Ti/SiO2/Si(100) substrate by sol–gel method. X-ray diffraction patterns show that the thin films have a good crystallinity. Optical properties of the films in the wavelength range of 2.5–12μm are studied by infrared spectroscopic ellipsometry (IRSE). The optical constants of the BZT thin films are determined by fitting the IRSE data using a classical dispersion formula. As the wavelength increases, the refractive index decreases, while the extinction coefficients increase. The effective static ionic charges are derived, which are smaller than that in a purely ionic material for the BZT thin films. [Copyright &y& Elsevier]

Abstract: The Ba(Zr x ,Ti1− x )O3 (BZT) thin films on Pt(111)/Ti/SiO2/Si(100) substrates were fabricated by a sol–gel-hydrothermal (SGHT) process. The microstructural characteristics proved that the prepared BZT thin films with well-developed crystallinity and good surface morphology were converted from the amorphous phase to the perovskite phase at very low-temperature processing of 100–200°C. The infrared optical properties of the BZT thin films have been investigated using an infrared spectroscopic ellipsometry in the wave number range of 800–4000cm−1 (2.5–12.5μm) by fitting the measured pseudodielectric functions with a three-phase model (Air/BZT/Pt), and a derived classical dispersion relation for the thin films. The optical constants of the thin films have been simultaneously obtained. [Copyright &y& Elsevier]

Abstract: By a chemical solution deposition method, 92%Pb(Mg1/3Nb2/3)O3–8%PbTiO3 (PMNT) thin films have been prepared on LaNiO3 (LNO)-coated (100) silicon and sapphire substrate. X-ray diffraction analysis shows the PMNT thin films on LNO-coated silicon as polycrystals with (100)-preferential orientation. A Pt/PMNT/LNO capacitor has been fabricated and it showed that the PMNT thin films have obvious ferroelectric character, with saturation polarization (P s), remanent polarization (P r) and coercive field (E c) of 25.5μC/cm2, 11.9μC/cm2 and 168kV/cm, respectively. The dielectric constant (εr) reaches 270 and the dissipation factor is very low at 1kHz. By the optical transmission spectra measurement, the optical constants (n and k ) and absorption coefficient (α) of the PMNT thin films on sapphire substrate in the wavelength range of 200–1100nm are all obtained. The energy gap (E g) of the PMNT thin films on the sapphire substrate was found to be about 4.03eV. [Copyright &y& Elsevier]

Objective: To investigate the screening value and correlation of body measurement indicators for metabolic syndrome(MS) and to provide evidence for MS screening., Methods: Through a cross-sectional research approach, data from individuals aged 18 and above who participated in health examinations at the North Health Management Center of Sichuan Provincial People's Hospital from 2018 to 2020 were reviewed. Data including height, weight, waist circumference, hip circumference, systolic blood pressure, diastolic blood pressure, fasting plasma glucose, triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, smoking history, and alcohol consumption history were collected. Subsequently, a body shape index(ABSI), body roundness index(BRI), body adiposity index(BAI), abdominal volume index(AVI), relative fat mass index(RFM), and body mass index(BMI) were computed. The individuals were then divided into MS and non-MS groups. The value of body measurement indices in screening for MS in the population aged 18 and above was assessed using ROC curves. Regression analysis was employed to explore the correlation between body measurement indices and MS., Results: A total of 73 411 valid health examination data were obtained, including 44 426 males and 28 985 females. The MS group comprised 9181 males(21%) and 1668 females(6%). In the comparison between the MS and non-MS groups, there were statistically significant differences in ABSI((0.08±0.00) vs. (0.08±0.00)), BRI((4.95±0.67) vs. (4.17±0.68)), BAI((28.08±3.52) vs. (26.39±3.39)), AVI((17.51±2.77) vs. (12.85±2.91)), BMI((27.15±2.99) vs. (23.00±3.04)) and RFM((29.77±5.35) vs. (27.13±6.39))(P<0.05). Univariate Logistic regression analysis showed that ABSI(OR=2.303, 95%CI 1.190-4.457), BRI(OR=4.596, 95%CI 4.446-4.752), BAI(OR=1.144, 95%CI 1.137-1.151), AVI(OR=1.668, 95%CI 1.652-1.684), RFM(OR=1.067, 95%CI 1.064-1.071) and BMI(OR=1.516, 95%CI 1.503-1.528) were associated with MS(P<0.05). Multifactorial Logistic regression analysis corrected for sex, age, smoking and alcohol consumption showed that ABSI(OR=1.767, 95% CI 4.237-7.371), BRI(OR=5.441, 95% CI 5.228-5.663), BAI(OR=1.269, 95% CI 1.260-1.279), AVI(OR=1.648, 95% CI 1.631-1.665), RFM(OR=1.504, 95% CI 1.491-1.517) and BMI(OR=1.508, 95% CI 1.495-1.522) were associated with MS(P<0.05). The ROC curve analysis showed that in adults, the AVI had the highest screening value for MS in males(AUC=0.855, optimal cutoff value=16.18), followed by RFM(AUC=0.844, optimal cutoff value=25.71), BMI(AUC=0.811, optimal cutoff value=25.21), BRI(AUC=0.793, optimal cutoff value=4.39), BAI(AUC=0.709, optimal cutoff value=25.88), and ABSI(AUC=0.671, optimal cutoff value=0.08). In adult females, the RFM had the highest screening value for MS(AUC=0.918, optimal cutoff value=37.01), followed by AVI(AUC=0.911, optimal cutoff value=13.43), BRI(AUC=0.901, optimal cutoff value=4.71), BMI(AUC=0.860, optimal cutoff value=23.94), ABSI(AUC=0.804, optimal cutoff value=0.08), and BAI(AUC=0.797, optimal cutoff value=29.92)., Conclusion: ABSI, BRI, BAI, AVI, BMI and RFM are all capable of screening for MS. Among males, AVI has the highest screening value for MS, followed by RFM, BMI, BRI, BAI and ABSI. Among females, RFM has the highest screening value for MS, followed by AVI, BRI, BMI, ABSI and BAI. ABSI, BRI, BAI, AVI, RFM and BMI are positively correlated with MS.

Objective: To investigate the effectiveness of double internal fixations of clavicle and scapula and intraoperative reduction of glenopolar angle in the treatment of floating shoulder injuries., Methods: Between January 2010 and June 2019, 13 patients with floating shoulder injury were treated with double internal fixation of clavicle and scapula and intraoperative reduction of glenopolar angle. There were 11 males and 2 females with an average age of 48 years (range, 25-65 years). The causes of injury included falling from height in 2 cases, traffic accident injury in 3 cases, heavy object injury in 2 cases, and other injuries in 6 cases. There were 2 cases of Ⅰ-B-3 type, 1 case of Ⅰ-C-2 type, 1 case of Ⅰ-C-3 type, 3 cases of Ⅱ-B-2 type, 1 case of Ⅱ-B-3 type, 1 case of Ⅱ-B-4 type, 2 cases of Ⅱ-C-2 type, 1 case of Ⅱ-C-4 type, and 1 case of Ⅱ-D-3 type according to the classification of floating shoulder injury. All patients had unilateral clavicle fracture with scapular neck fracture, 1-4 superior shoulder suspensory complex (SSSC) injuries. The time from injury to operation was 7-17 days, with an average of 12 days. The glenopolar angle, subacromail space, anteroposterior inclination angle of scapular glenoid, scapular glenoid up and down angle were measured before and after operation; Constant-Murly score and Herscovici score were used to evaluate the recovery of shoulder joint function., Results: All incisions healed by first intention, and there was no early postoperative complications such as infection. All 13 cases were followed up 12-48 months, with an average of 25.2 months. Both the clavicle and the scapula had bone union, and the average healing time was 6 months and 4 months respectively. There were no complications such as nonunion, shoulder deformity, plate fracture or failure of internal fixation, acromion impingement syndrome, and frozen shoulder. At last follow-up, the glenopolar angle, subacromail space, anteroposterior inclination angle of scapular glenoid, and scapular glenoid up and down angle were all corrected significantly ( P <0.05). The pain, function, activity, muscle strength scores, and total score in Constant-Murly score were significantly improved when compared with preoperative scores ( P <0.05). According to the Herscovici scoring standard, the shoulder joint function was evaluated as excellent in 8 cases, good in 3 cases, and fair in 2 cases. The excellent and good rate was 84.6%., Conclusion: Double internal fixation of clavicle and scapula to stabilize SSSC and reduct glenopolar angle during operation is an effective method for treating the floating shoulder injury.
