Two-dimensional hybrid perovskite crystals for highly sensitive and stable UV light detector

Two-dimensional metal halide perovskites (2D MHPs) are promising candidates for ultraviolet (UV) light detection due to their narrow band gap and high stability in the air atmosphere. MHP crystals, with fewer defects and grain boundaries than polycrystalline films, are more suitable for photodetectors and other advanced semiconductor devices. In this paper, aimed to fabricate high-performance UV light detector, a series of high-quality and large-sized 2D perovskite crystals with the composition of (BA)2Pb(ClxBr1-x)4 were prepared and the best UV responsibility was found in the (BA)2Pb(Cl0.1Br0.9)4 crystal. Despite the detector was fabricated by the simple silver brushing method, it exhibits high responsivity of 3.19 mA/W, high detection rate of 3.87 × 1011 Jones, and fast response speed to UV light of 340 nm under the bias of 20 V. Moreover, the detector shows remarkable light sensitivity even under extremely weak UV illumination of 5.4 μW/cm2 and satisfactory stability during a long-duration switching operation. The excellent light response performance of the (BA)2Pb(Cl0.1Br0.9)4 detector was ascribed to the very low dark current (0.84 pA) of the detector, which highly relies on the crystal quality of the light-absorbing perovskites. The relationship between the structural and the compositional characteristics of (BA)2Pb(Cl0.1Br0.9)4 and its light response property was analyzed. This work provides a promising candidate material for sensitive UV detection and high-performance photodetectors.

The aim of the study was a comprehensive assessment of liver changes in laboratory rabbits under the conditions of the experiment with the intake of water-soluble silicon for three months. Material and methods. Rabbits were kept in a vivarium on a standard diet with free access to drinking water for three months. Animals of the control group (n = 3) received bottled drinking water, rabbits of the experimental group (n = 3) received the same water, but with the addition of sodium metasilicate enneahydrate at a concentration of 20 mg /l expressed in terms of silicon. After the animals were removed from the experiment, the liver was extracted. A part of the liver was sent to a cryostat for freezing with further preparation of fresh slices with a thickness of 10 microns and producing a Cross, Evan and Rost reaction to detect histamine luminescent structures, the other part was placed in a 10% formalin solution for subsequent paraffin embedding. Paraffin blocks were made; sections of 5 microns thick after deparaffination were stained with hematoxylin and eosin, methyl green-pyronine by Brachet method, as well as by Van Gieson method to identify connective tissue. The measurement results were considered statistically significant at p < 0.05. Results and their discussion. When stained with hematoxylin and eosin in the liver preparations of rabbits of the experimental group who received silicon with drinking water at a concentration of 20 mg/l ad libitum for three months, statistically significant increases in the average area of hepatocytes, the average area of hepatocyte nuclei, and the average diameter of sinusoidal capillaries were revealed in comparison with the preparations in the control group. An increase in the area of central veins was noted, but these changes were not statistically significant. A change in the shape of hepatocytes' nuclei was observed, which was manifested by a decrease in the shape factor of the nucleus and eccentricity and an increase in the index of the nucleus contour, as well as leukocytic infiltration of the portal tract area, formation of areas of hepatocytes' focal necrosis, proliferation of connective tissue with the formation of portal fibrosis and portoportal septa. In rabbits of the experimental group, a decrease in the DNA optical density was determined in liver histopreparations stained by Brush method in hepatocyte nuclei. We found an increase in the intensity of histamine luminescence in the luminescent granular liver cells of rabbits containing it. Conclusions. The intake of silicon at a concentration of 20 mg/l for three months results in pronounced morphological changes in the liver of rabbits.

In situ formed interfacial layer for all-solid-state lithium batteries with sulfide electrolyte films

Sulfide solid-state electrolytes (SEs) are considered as a promising alternative to traditional liquid electrolytes, owing to their low interfacial resistance and high ionic conductivity. Nevertheless, Li dendritic growth in SEs have greatly restricted the development of the high energy of All-solid-state lithium batteries (ASSLBs). In this study, a protective layer is synthesized at the Li metal surface via a solvent-free brushing method with the chemical reaction between Li metal and P2S5 particles. The P2S5@Li layer have satisfactory high interfacial energy, which is verified by density functional theory calculation. The P2S5@Li/LPSCl films/P2S5@Li symmetrical cells can cycle for >500 h at 0.1 mA cm−2. Notably, the P2S5@Li/LPSCl films/LiNbO3@LiNi0.8Co0.1Mn0.1O2 cells can deliver a discharge capacity of 155.7 mA h g−1 and excellent capacity retention of 75.5% over 400 cycles at 0.5C. This study has developed an innovative approach to ameliorate the interface of Li metal anode and practical application of ASSLBs.

Effect of ZrB2 and Polyvinyl Butyral Content on the Oxidation Resistance of ZrB2–SiC Coatings Produced by Slurry Brushing Method

ZrB2–SiC coatings are prepared on the surface of graphite by slurry brushing method to improve the oxidation resistance. Effects of ZrB2 content and polyvinyl butyral (PVB)–ethanol solution concentration on microstructure and static oxidation behavior of the ZrB2–SiC coatings are investigated at 1200 °C in air. The results indicate that increasing ZrB2 content improves the oxidation resistance of the coatings. When ZrB2 content increases from 30 to 45 wt%, weight loss rates of the coated samples after oxidation at 1200 °C for 120 min decrease from −0.92% to −1.67%. Increasing binder solution concentration raises component content in the coatings. As PVB–ethanol binder concentration increases from 0.025 to 0.075 g mL−1, weight loss rates of the coated samples after oxidation at 1200 °C for 120 min decrease from 0.32% to −0.38%. Excellent oxidation resistance of ZrB2–SiC coating is attributed to self‐sealing ability of B2O3 and borosilicate glass. The composite glass can inhibit oxygen diffusion by filling defects in the coating promptly. The borosilicate glass phase can enhance the fluidity of the composite glass. ZrO2 and ZrSiO4 particles restrict the growth of the microcrack, which improves the oxidation resistance of ZrB2–SiC coating.

Evaluation of the cleaning efficacy of a normal toothbrush and a manual U shaped toothbrush in children aged 8–10 years: A randomized crossover trial

ABSTRACT Background: Plaque removal rates are influenced by toothbrush design as well as brushing methods. Aim: The study aimed to determine the efficacy of a manual U-shaped toothbrush when compared to a regular toothbrush in removing dental plaque from teeth in children aged 8–10 years. Materials and Methods: Our research included 40, 8–10-year-old children. Stage I included days 0–7, while Stage II covered days 8–15. A disclosing agent was used to identify and score the dental plaque. During Stage I of the study, Group I was given a regular toothbrush, and Group II was given a U-shaped toothbrush. During Stage II of the study, the cross-over of interventions was carried out. Loe-Silness gingival index and Turesky modification of the Quigley-Hein index were measured on the 8th and 16th day. Unpaired t-test/independent samples t-test were performed for comparison between the groups. Results: The intergroup evaluation of plaque scores on various surfaces between the two groups revealed statistically significant differences (P = 0.05) between the mean plaque scores at stage I on the labial surface (P = 0.001) and the lingual surface (P = 0.002) between the two groups. Comparing gingival health scores of various surfaces between the two groups, mesial, labial, distal, and lingual surfaces revealed statistically significant differences (P = 0.05) at stage II and lingual surfaces at stage I and stage II, respectively. Conclusion: The experimental U-shape toothbrush significantly reduced the extent of plaque on the lingual surfaces and improved the gingival index scores, which helped improve gingival health and oral hygiene.

The Impact of an Oral Hygiene Education Module on Inflammatory Factors in Patients with Active Systemic Lupus Erythematosus

Background: In patients with active systemic lupus erythematosus (SLE), inflammatory markers such as erythrocyte sedimentation rate (ESR) and serum C-reactive protein (CRP) are often elevated. Increases in these inflammatory biomarkers have been linked to periodontal diseases. Objectives: This study aimed to investigate the impact of oral health education on inflammatory markers in patients with SLE. Methods: In this field trial study, 40 SLE patients with no dental plaque were assigned to the intervention and control groups by block randomization design. The intervention group was educated in a 20-minute session based on Bass’s method of tooth brushing. Before and 3 months after the intervention, the dental plaque, CRP, ESR, and double-stranded DNA (anti-dsDNA) levels were determined in the two groups. Data were analyzed with SPSS software using independent t-test, Wilcoxon, Mann-Whitney, and univariate covariance analysis at 0.05 significance level. Results: In terms of basic variables, there was no significant difference between the two groups. O’Leary’s plaque index in the intervention group showed a significant decrease over time, but no significant reduction was observed in the control group. The difference between the two groups was statistically significant (P < 0.001). The results of covariance analysis and controlling for the effect on patients' performance showed that the health education intervention had a significant impact on ESR (effect size = 9.6%). However, the intervention had a slight effect on CRP, dsDNA, and SLE Disease Activity Index (SLE-DAI). Moreover, CRP, ESR, and dsDNA showed a significant decrease in both groups after the intervention; however, the difference was not significant. Conclusions: According to the results of the study, it is recommended to implement educational programs in the field of oral and dental hygiene and the correct way of brushing teeth for patients with SLE.

A facile brushing method for constructing all-in-one high performance flexible supercapacitor with ordinary carbon materials

Flexible supercapacitors require some important characteristics such as good structural style and high performance, but low cost and easy manufacturing should not be ignored. Herein, we design flexible supercapacitors based on ordinary carbon materials. By using acetylene black as the conductor, this new type of flexible supercapacitor was built through brushing and realized the integration of electrode, supporting diaphragm and solid electrolyte. With this new structural form, the devices show extremely high tensile strength and good folding resistance. Supercapacitors can also be loaded with different active materials and exhibit many excellent electrochemical properties. When using polyaniline coated multi-wall carbon nanotube as the active material, it shows a surface capacity of 1 Fcm−2 level and a good rate performance. In the case of using activated carbon, it shows a good response and a good capacity retention of 100 ± 1 % and high coulomb efficiency. It can stably work at a temperature range of 5–55 °C. Even if injured, it can be used consistently. Our research may provide some references for the large-scale fabrication of new flexible supercapacitors.

OralMate: Intelligent Brushing Monitoring Using a Smart Toothbrush

Tooth Brushes are the most commonly used oral hygiene aids. Dental plaque, a sticky, colourless film of bacteria build-up and covers the enamel of the teeth and can cause tooth decay, gum disease, and dental disease. So, it is very important to remove dental plaque to keep teeth clean and healthy. OralMate is an IOT enabled smart toothbrush. OralMate helps in monitoring the pressure while brushing teeth, keeps check of the duration of the brushing and monitors the intensity of brushing. OralMate comes with an application that keeps a record of the brushing sessions and related parameters. The main aim is to help people to maintain their oral health. OralMate is an effective way to help people develop a proper brushing method to keep their teeth healthy. A proper brushing method includes many factors, like the pressure applied on the teeth, the number of brush strokes, and the time duration for which the brushing is done. These factors fulfilled individually might not be enough and must be fulfilled as a whole.

Designing vivid green Sr9Al6O18:Er3+ phosphor for information encryption and nUV excitable cool-white LED applications

Advanced forensic applications and optoelectronics both heavily rely on rare earth (RE) element activated luminous phosphor materials. We used latent fingerprints (LFPs) and white light-emitting diodes (w-LEDs) to detect Using an easy solution combustion technique, a single-phase green-emitting Sr9Al6O18:Er3+ (1–11 mol%) (SAO: Er) nanophosphor was created. The X-ray diffraction and Rietveld refinement were used to examine crystallographic data. The phosphors showed vivid-green luminescence when stimulated by 378 nm near ultraviolet (nUV). The concentration of Er3+ ions is observed to affect the photoluminescence emission (PLE) intensity, reaching its highest value at 5 mol% doping. The optimized phosphor is used in latent finger print (LFP), lip print (LP) and anti-counterfeiting (AC) applications. Under 378 nm excitation, multilevel features of the phosphor-attached LFPs could be clearly identified. The high colour contrast between the ridge and valley lines made for an excellent observation. We have developed simple brush and screen-printing methods for creating a variety of patterns using our custom anti-counterfeit security ink. In addition to this, the obtained AC tags exhibit high resolution and long-term durability. These characteristics clearly demonstrated that the current phosphor is an excellent luminescent material for data storage applications.

5nm Ultrathin Crystalline Ferroelectric P(VDF-TrFE)-Brush Tuned for Hysteresis-Free Sub 60mV dec-1 Negative-Capacitance Transistors.

Negative-capacitance field-effect transistors (NC-FETs) have gathered enormous interest as a way to reduce subthreshold swing (SS) and overcome the issue of power dissipation in modern integrated circuits. For stable NC behavior at low operating voltages, the development of ultrathin ferroelectrics (FE), which are compatible with the industrial process, is of great interest. Here, a new scalable ultrathin ferroelectric polymer layer is developed based on trichloromethyl (CCl3 )-terminated poly(vinylidene difluoride-co-trifloroethylene) (P(VDF-TrFE)) to achieve the state-of-the-art performance of NC-FETs. The crystalline phase of 5-10nm ultrathin P(VDF-TrFE) is prepared on AlOX by a newly developed brush method, which enables an FE/dielectric (DE) bilayer. FE/DE thickness ratios are then systematically tuned at ease to achieve ideal capacitance matching. NC-FETs with optimized FE/DE thickness at a thickness limit demonstrate hysteresis-free operation with an SS of 28mV dec-1 at ≈1.5V, which competes with the best reports. This P(VDF-TrFE)-brush layer can be broadly adapted to NC-FETs, opening an exciting avenue for low-power devices.

Solar reflective superhydrophobic coatings with phase change function

In this work, white Portland cement (WPC) based composite coatings consisting of WPC, building glue, phase change microcapsules, TiO2 particles, polymethylhydrosiloxane, and SiO2 particles were developed via a brushing method. After adjusting the variety and content of additives, the optimized WPC coating (PCM30S/WPCM) exhibits a phase transition temperature of 35 °C, solar reflectivity of 0.764, contact angle of 157.6°, and rolling angle of 7.1°. The coating shows stable superhydrophobicity in the corrosion test, mechanical abrasion test, ultraviolet (UV) aging experiment, and temperature fluctuation experiment. In addition, the superhydrophobic WPC composite coating exhibits a significant cooling effect of 8.5 °C under simulated solar radiation. Furthermore, the phase change coating can also prevent large fluctuation of coating surface temperature through phase change function, so as to improve building comfort. The simulation analysis indicates that the energy saving rate of the superhydrophobic phase change coating is the highest in Guangzhou, China, which is 23.2%.

Oral health behavior and oral health service utilization among cancer patients in China: A multicenter cross-sectional study.

Oral health plays an important role in overall health. But there is scarce information available on oral health behavior and oral health service utilization among cancer patients. This study aimed to evaluate oral health behavior and oral health service utilization among different population groups of cancer patients in China. A multicenter cross-sectional study in three tertiary hospitals was conducted to explore the oral health behaviors and oral health service utilization of 162 cancer patients in China. We investigated a total of 162 cancer patients, 81 from urban and rural areas, respectively. The participant's ages ranged from 18 and 82 years, mean age was 44.62 years (SD = 15.72). Overall, cancer patients have poor oral health behaviors and limited oral health service utilization. There were statistically significant differences (p < 0.05) between urban and rural cancer patients in terms of oral health behaviors, including brushing methods, the use of fluoride toothpaste, the use of dental floss, dental caries, and bleeding gums while brushing teeth. As for oral health service utilization, there were significant differences (p < 0.05) between urban and rural cancer patients on regular dental cleaning, the reasons for visiting a dental clinic, and whether they took the initiative to learn about oral health. The study findings suggest that cancer patients had poor oral health behaviors and limited oral health service utilization, and rural patients perform poorer than their urban counterparts. Oral health education should be provided to cancer patients to improve their oral health behaviors and oral health service utilization.

Long-lasting self-cleaning daytime radiative cooling paint for building

Endowing the building exterior wall with superhydrophobicity and radiation cooling function can not only achieve building energy conservation, but also significantly reduce the cost of manual cleaning, so as to ensure the efficiency and durability of the radiant cooling function of the building exterior wall. However, it is still a challenging work to make coatings (paint films) with the above two functions on the surface of large external walls. Herein, we have developed a polyvinylidene fluoride/polydimethylsiloxane (PVDF/PDMS) composite coating composed of PVDF particles and PDMS binder, which is prepared by one-step brushing method. It exhibits solar reflectivity of 90.6%, infrared emissivity of 98.1%, contact angle of 158.2° and rolling angle of 7.9°. The PVDF/PDMS coating exhibits a radiative cooling temperature of 4.93 °C under direct solar irradiation. Importantly, both the DRC function and the superhydrophobicity of the PVDF/PDMS film exhibit excellent weatherability during the one-year outdoor weather resistance test and remarkable mechanical durability in sandpaper abrasion and sand impact tests. Therefore, the long-term self-cleaning DRC paint developed in this work has a potential application prospect in the field of building exterior wall or roof.

All-Polymer Superhydrophobic Radiative Cooling Coating Based on Polytetrafluoroethylene/Polydimethylsiloxane Composites

In the present work, a polytetrafluoroethylene/polydimethylsiloxane (PTFE/PDMS) composite coating was fabricated using a simple brushing method. The PTFE/PDMS coating has both superhydrophobic self-cleaning property and radiation cooling function. The contact angle (CA) for water of the composite coating is 159.3°, and the sliding angle (SA) for water is 6.3°. Furthermore, the solar reflectivity of the coating in the wavelength range of 200–2500 nm is close to 92%, and the infrared emissivity in the 8–13 μm middle-infrared band is about 0.93. When the maximum daytime temperature in summer is 39 °C, the PTFE/PDMS coating could achieve an average radiation cooling temperature of 4.73 °C under direct sunlight from 10:00 a.m. to 16:00 p.m. Under the same conditions, covering the PTFE/PDMS coating on the electric vehicle seat cushion could realize the temperature drop of the seat cushion by 19.41 °C. After continuous washing and corrosion of 50,000 mL of simulated acid rain, 10 cycles of ultraviolet (UV) aging experiments, or 25 cycles of sandpaper abrasion, the superhydrophobicity and radiation cooling function of the PTFE/PDMS coating remained unchanged. In particular, the PTFE/PDMS coating lost the radiative cooling ability after the surface is contaminated. However, with the help of natural rainfall, its radiation cooling coating could recover rapidly. Therefore, the PTFE/PDMS coating developed in this work makes the radiative cooling coating more practical.

Comparative evaluation of Tooth Surface Abrasiveness of Herbal and Non-herbal Toothpaste.

Background: Abrasion is the mechanical wearing of dental hard tissue and commonly affects cervical tooth structure. The main predisposing factors for abrasion are the tooth brushing method and the type of toothpaste used. Toothpaste is an important component in the etiology of abrasion. Most toothpaste contains abrasive agents for cleaning, maintaining, and improving tooth health. There are two types of toothpaste commercially available; synthetic and herbal formulations. Synthetic toothpastes typically contain abrasive agents, such as calcium phosphate, calcium carbonate, silica or hydrated silica for removing debris and stains. High amounts of abrasives in toothpastes may damage hard and soft tissues and dental restorations, leading to gingival recession, cervical abrasion and dentinal hypersensitivity. The purpose of this study is to investigate the abrasive effect of herbal toothpastes compared with non-herbal toothpaste.&#x0D; &#x0D; Methods: 300 patients were randomly selected those who fulfilled the eligibility criteria. Subjects participating in this study were equally divided into 2 groups. Group A: Herbal toothpaste, Group B: Non Herbal tooth gel. The presence and type of cervical defects in each person will be diagnosing using the tooth wear index (TWI).&#x0D; &#x0D; Results: Statistically significant difference was observed in value of enamel abrasion amongst Group A and B (p&lt;0.05). Statistical analysis used in this study was one-way analysis of variance (ANOVA)&#x0D; &#x0D; Conclusions: The least enamel abrasion was observed in non herbal tooth gel when compared with herbal toothpaste.&#x0D;
