Purpose: Under the umbrella of social cognitive theory, we examined the influences of personal, environmental, and behavioral factors on adherence to healthy eating behaviors among colorectal cancer survivors. Methods: Based on Pluye and Hong’s framework, a systematic mixed studies review was conducted. An extensive search strategy was applied in PubMed, Web of Science, Embase, CINAHL, and PsycINFO (from date of record to 2022 January 22). The pillar integration process was employed to integrate the extracted data. The Mixed Methods Appraisal Tool was used to appraise the quality of all retained studies. Results: Twenty-eight studies with a total sample size of 5106 were included in the analysis, with 15 quantitative studies, 12 qualitative studies, and 1 mixed method study. The critical appraisal showed that 22 of the 28 studies (79%) were rated with five stars, while 6 (21%) were rated with four stars. The personal factors influencing adherence to healthy eating behaviors among colorectal cancer survivors included outcome expectancies, self-efficacy, psychological factors, knowledge about healthy eating, demographic and disease characteristics, environmental factors incorporated outside information on healthy eating, power of surrounding people, social activities, cultural milieus, socioeconomic status, and education. The behavioral factors included self-regulation of diet, goals, and other behaviors closely related to healthy eating behaviors. Conclusions: Adherence to healthy eating behaviors among colorectal cancer survivors was influenced collectively by personal factors, environmental factors and behavioral factors.

Application of VUV/UV process for micropollutants removal in decentralized water supply systems (e.g., rural drinking water treatment) is promising while few researches by far paid attention to the performance of practical flow-through reactors. This study investigated the degradation of atrazine (ATZ), sulfamethoxazole (SMX) and metoprolol (MET) under different hydrodynamic conditions in reactors with varied internal diameters and baffle allocations. Results showed that the target micropollutants could be degraded efficiently in the flow-through VUV/UV reactors following basically the pseudo-first order kinetics (R2 ≥ 0.97). The largest degradation rate constants were found in the D35 reactor and incorporation of baffles in the D50 and D80 reactors accelerated obviously the micrpollutants degradation. The improved performances of the baffled reactors were due mainly to the elevated utilization of HO•, and a new parameter named UE HO (HO• utilization efficiency) was proposed accordingly. The calculated UE HO values of the reactors ranged between 30.2% and 69.2% with the largest found in the D50-5 reactor. This testified the usually insufficient utilization of radicals in flow-through reactors and the effectiveness of baffle implementation. Electrical energy per order (E EO) values of micropollutants degradation in the reactors were in the range of 0.104–0.263 kWh m−3 order−1. The degradation was inhibited significantly by high-concentration nitrate yet the formed nitrite concentration stayed consistently below the drinking water limitation. The acute toxicity of the micropollutant solutions increased first and leveled off afterwards during the VUV/UV treatment, as indicated by the inhibition ratios of luminescence intensity of Vibrio fischeri. [Display omitted] • Micropollutants were degraded in different flow-through VUV/UV reactors. • Impact of reactor configuration on utilization efficiency of HO.• was evaluated. • The Lowest E EO was found with a proper internal diameter and baffle allocation. • Nitrite formation in tested flow-through VUV/UV reactors was not concerning. • Acute toxicity of the solution tended to increase during VUV/UV treatment.

Soft hydrogel iontronic devices, utilizing the assumed non‐Faradaic exchange of ions and electrons at the metal‐hydrogel interfaces, have been demonstrated with advantages of high stretchability, transparency, and biocompatibility. Yet, in real situation under high voltage, Faradaic reaction is inevitable, which can breakdown the device and lead to the low durability. Herein, the Faradaic breakdown behaviors of hydrogel iontronic devices under high AC voltage are systematically studied. Side reactions including electrode corrosion and water electrolysis are confirmed in the electrical double layer. Interface barrier layers are proposed to eliminate this issue. It is found that acetylene black (ACET) as modification layer can achieve the best performances, providing effective protection while maintaining the electrical performances. By leveraging ACET‐modified electrodes, long‐term durable iontronics, including electroluminescent devices and high‐output triboelectric nanogenerators, are successfully demonstrated. This work can provide insightful strategies for developing practical hydrogel iontronic devices. [ABSTRACT FROM AUTHOR]

Soft iontronics expand the toolbox of bio‐integrated or bio‐interfaced devices, owing to their natural resemblance with living systems; however, the development for analogous integrated ionic circuits is immature due to the difficulty of fabricating fundamental ionic logic elements. Among these, ionic diodes have motivated great endeavors for their unique ionic current rectifying characteristics. Nonetheless, it is still challenging to achieve high‐performance ionic diodes; also, most reported aqueous solution‐based ionic diodes fail to work at extreme temperatures, seriously hindering their practical uses. This work reports a highly rectifying, temperature‐tolerant, and flexible hydrogel ionic diode enabled by an ethylene glycol/water binary solvent system. The ionic diodes exhibit outstanding dehydration resistance to high temperatures (100 °C) and anti‐freezing performance at low temperatures (−20 °C). Rectification ratios as high as 1201 (with 0% ethylene glycol content) and 566 (with 40% EG content) are achieved, which are distinctly advantageous over most previous reports. A flexible four‐diode bridge full‐wave rectifier circuit is then fabricated, and its integration with the triboelectric nanogenerator for effective biomechanical energy harvesting is demonstrated. This work is believed to open up new insights for the development of future bio‐interfaced applications. [ABSTRACT FROM AUTHOR]

[Display omitted] • Mechanical stimuli-triggered optical responses of cholesteric liquid crystal devices are realized. • Self-powered bistable smart window and E-paper are demonstrated. • Self-powered optical switch is developed for remote control. Intelligent responsive devices are crucial for a variety of applications ranging from smart electronics to robotics. Electro-responsive cholesteric liquid crystals (CLC) have been widely applied in display panels, smart windows, and so on. In this work, we realize the mechanical stimuli-triggered optical responses of the CLC by integrating it with a triboelectric nanogenerator (TENG), which converts the mechanical motion into alternating current electricity and then tunes the different optical responses of the CLC. When the voltage applied on the CLC is relatively low (15–40 V), the TENG drives the switching between the bistable planar state and focal conic state of the CLC, which shows potential applications in self-powered smart windows or E-paper displays. When the voltage supplied by the TENG is larger than 60 V, a self-powered optical switch is demonstrated by utilizing the transformation between focal conic state and instantons homeotropic state of the CLC. This triboelectric-optical responsive device consumes no extra electric power and suggests a great potential for future smart electronics. [ABSTRACT FROM AUTHOR]

An ordered mesoporous Mg-Al layered double hydroxide (meso-LDH350) with a fairly high Brunauer-Emmett-Teller (BET) surface area (126 m 2 g −1 ) has been facilely synthesized and then evaluated for the adsorptive removal of bromate from aqueous solutions. Adsorbents were characterized by a variety of techniques (e.g., XRD, FTIR, SEM, TG-DSC, N 2 physisorption, XPS, etc.). The adsorption studies indicated that the presence of background electrolytes and competitive anions can obviously repress the uptake of bromate on LDHs. The adsorption isotherms agree well with the Langmuir model, giving a maximum adsorption capacity of 59.34 mg g −1 (pH 7.5, 10 °C) for meso-LDH350, which is much higher than other LDH-type adsorbents reported in literature. The adsorption kinetic data can be well fitted with the pseudo-second-order rate model. Based on the macroscopic and microscopic studies, bromate adsorption on meso-LDH350 was associated with two mechanisms: the reconstruction of the layered structures of meso-LDH350 and the anion-exchange between bromate and the intercalated anions.

The degradation of three micropollutants (i.e., atrazine (ATZ), sulfamethoxazole (SMX) and metoprolol (MET)) was comprehensively investigated in flow-through UV/chlorine reactors. Results showed that the micropollutants degradation fitted well with pseudo-first-order kinetics (R2 > 0.92) with the order of rate constants following SMX > MET > ATZ. The developed steady-state approximation (SSA) model was roughly applicable in flow-through UV/chlorine reactors with the predictions deviated within 44%. UV photolysis here stood as the major degradation pathway for ATZ while the contribution of non-radical processes (UV photolysis and chlorination) to SMX degradation increased as the reactor internal diameter enlarged. The degradation rates were reduced to varying extents with complex water matrices (chloride, bicarbonate and dissolved organic matter (DOM)) where the inhibition from the DOM was most prominent (up to 73.6%). Although reactors with a larger internal diameter resulted in reduced degradation rate constants, the energy requirements were also lowered. The E EO values of micropollutants degradation by UV/chlorine fell mostly within 1.0 kWh m−3 order−1 in deionized water and under different water matrices. The acute toxicity was observed to be higher after UV/chlorine treatment in tap water, but still stayed low in general. This study revealed the different kinetics and mechanisms of micropollutants degradation in flow-through reactors and demonstrated the potential of the UV/chlorine process in terms of low energy consumption and acute toxicity. [Display omitted] • Micropollutants were efficiently degraded in flow-through UV/chlorine reactors. • A steady-state approximation model was developed and found approximately applicable. • Effects of reactor internal diameter and water matrices were investigated. • Variations of solution acute toxicity during UV/chlorine treatment were evaluated.
