Journal of Membrane science Letters 2023年第2期3卷

Metal-organic frameworks (MOFs) hold great promise as porous materials for pervaporation applications. However, the exploration of MOF membranes in this field is still in its early stages. One of the main challenges is the relatively low mass flux and stability of pure MOF membranes compared to other materials used in pervaporation. In this study, we propose a novel approach to enhance the separation performance of MOF membranes for water and ethanol separation. Our strategy involves incorporating the 2,5-thiophenedicarboxylic acid (TDC) linker into the MOF-303 structure, partially replacing the 3,5-pyrazoledicarboxylic acid (PDC) linker. The goal is to increase the aperture size of the microporous channels in the pristine MOF-303 membrane, thereby improving the mass flux. X-ray diffraction characterization, combined with Rietveld refinement, confirmed that the partial substitution of PDC with TDC resulted in an increased pore-limiting diameter (PLD) of MOF-303. For instance, the pristine MOF-303 exhibited a PLD of 5.78 Å, while MOF-303(70/30) with 70% TDC replacement displayed a PLD of 6.02 Å. To fabricate the mixed-linker MOF-303 membranes, we utilized a seeded growth method, which yielded membranes with dense layers, as confirmed by scanning electron microscopy and air permeation characterization. The prepared membranes were subjected to pervaporation tests to evaluate their performance in separating 90 wt.% ethanol at 60 °C. The pristine MOF-303 membrane exhibited notable separation capabilities, with an average flux of 0.071 kg·m −2 ·hr −1 and a water/ethanol separation factor of 5371. Surpassing the unmodified MOF-303, the mixed-linker MOF-303(50/50) membrane demonstrated improved mass flux and water/ethanol separation factor. Specifically, the MOF-303(50/50) membrane displayed an average flux of 0.092 kg·m −2 ·hr −1 and a water/ethanol separation factor of 8500. Importantly, the unmodified MOF-303 membrane exhibited instability during prolonged pervaporation

The electrocatalytic urea oxidation reaction (UOR) provides more economic electrons than water oxidation for various renewable energy-related systems owing to its lower thermodynamic barriers. However, it is limited by sluggish reaction kinetics, especially by CO2 desorption steps, masking its energetic advantage compared with water oxidation. Now, a lattice-oxygen-involved UOR mechanism on Ni4+ active sites is reported that has significantly faster reaction kinetics than the conventional UOR mechanisms. Combined DFT, 18O isotopelabeling mass spectrometry, and in situ IR spectroscopy show that lattice oxygen is directly involved in transforming *CO to CO2 and accelerating the UOR rate. The resultant Ni4+ catalyst on a glassy carbon electrode exhibits a high current density (264 mAcm-2 at 1.6 V versus RHE), outperforming the stateof- the-art catalysts, and the turnover frequency of Ni4+ active sites towards UOR is 5 times higher than that of Ni3+ active sites. © 2020 Wiley-VCH Verlag GmbH & Co.

Materials adopting the diamond structure possess useful properties in atomic and colloidal systems and are a popular target for synthesis in colloids where a photonic band gap is possible. The desirable photonic properties of the diamond structure pose an interesting opportunity for reconfigurable matter: Can we create a crystal able to switch reversibly to and from the diamond structure with a photonic band gap in the visible light range? Drawing inspiration from high-pressure transitions of diamond-forming atomic systems, we design a system of polyhedrally shaped colloidal particles with spherical cores that transitions from diamond to a tetragonal diamond derivative upon a small pressure change. The transition can alternatively be triggered by changing the shape of the particle in situ. We propose that the transition provides a reversible reconfiguration process for a potential new colloidal material and draw parallels between this transition and the phase behavior of the atomic transitions from which we take inspiration.

The metabolic reprogramming of tumors requires high levels of adenosine triphosphate (ATP) to maintain therapeutic resistance, posing a major challenge for photothermal therapy (PTT). Although raising the temperature helps in tumor ablation, it frequently leads to severe side effects. Therefore, improving the therapeutic response and promoting healing are critical considerations in the development of PTT. Here, we proposed a gas-mediated energy remodeling strategy to improve mild PTT efficacy while minimizing side effects. In the proof-of-concept study, a Food and Drug Administration (FDA)-approved drug-based hydrogen sulfide (H 2 S) donor was developed to provide a sustained supply of H 2 S to tumor sites, serving as an adjuvant to PTT. This approach proved to be highly effective in disrupting the mitochondrial respiratory chain, inhibiting ATP generation, and reducing the overexpression of heat shock protein 90 (HSP90), which ultimately amplified the therapeutic outcome. With the ability to reverse tumor thermotolerance, this strategy delivered a greatly potent antitumor response, achieving complete tumor ablation in a single treatment while minimizing harm to healthy tissues. Thus, it holds great promise to be a universal solution for overcoming the limitations of PTT and may serve as a valuable paradigm for the future clinical translation of photothermal nanoagents.

Tobacco plants are notably known for its pesticidal properties, particularly due to its nicotine content. In this study, Nicotiana tabacum L. bio-oil was obtained using pyrolysis technique. The safety of the bio-oil to be used as bioinsecticide was analyzed through acute oral toxicity test by administering 5000 mg bio-oil/kg body weight of female winstar rats that were analogous to humans. It was concluded that the bio-oil was not toxic due to absence of mortality and no significant change in the body weight and behavior of the rats. © Published under licence by IOP Publishing Ltd.

In present study, a simultaneous electrospinning and electrospraying（SEE） process was employed to produce microclusters of TiO2 nanoparticles and interlock them in nanofibrous network. The photocatalytic composite membranes（PCMs） were fabricated by electrospraying TiO2 nanoparticle suspension into microcluster form that dispersed and entrapped within nylon-6 electrospun fiber membrane. Three PCMs membrane with TiO2 content of 52.0, 83.6,and 91.7 wt.% were successfully fabricated. The membrane consisted of TiO2 microclusters,ranging in sizes from around 0.3 to 10 μm, distributed uniformly within the nylon-6 nanofibrous network. PCMs photocatalytic activity against Methylene Blue（MB） in aqueous solution showed more than 98% MB removal efficiency after 120 min of photocatalytic oxidation（PCO） for all PCMs. For PCM with the highest TiO2 content tested for 5 PCO cycles, it was found that most of their TiO2 content remained incorporated within the nanofibrous structure. The concept of nanoparticles clusters entrapment with SEE fabrication employed here provide a simple and effective method for reducing detachment of nanostructure phase from nanocomposite membrane.

In spite of considerable evidence of the effectiveness of active learning and other contemporary teaching methods, barriers to adoption of those methods, such as possible student resistance, continue to exist. This study addresses student resistance by analyzing data from 1,051 students who completed our Student Response to Instructional Practices (StRIP) instrument in 18 introductory engineering courses where active learning was implemented. Through descriptive statistics, correlation analyses, and hierarchical linear regression modeling, we demonstrate that students ‘perceptions of their instructors’ use of explanation and facilitation strategies can have a significant impact on student resistance. This study provides a more complete picture of the relative efficacy of these strategies to reduce resistance and confirms that students ‘perceptions of their instructors’ use of these strategies can influence both how students engage with active learning and how students evaluate the course and instructor. We provide evidencebased advice for both new and experienced instructors to reduce student resistance to active learning and other contemporary teaching methods. © 2018 National science Teaching Association.

Hazardous industrial solid wastes management on the cosmetic packaging industry

引用

AIP Conference Proceedings 2020年第1期2197卷

Hazardous industrial solid wastes require proper management to prevent negative impacts on human’s health and the environment. The generation of paint waste in the cosmetics industry is managed based on the hierarchy of waste management, starting from prevention, and then reduction, reuse, recycle, recovery and waste to product. Technical feasibility studies on improvement of the production and treatment of waste are used as an initial step in the selection of waste management models, followed by consideration of the environmental aspect and health effect of industrial workers. Efforts to reduce waste generation can be done by improving the production process and applying standard operating procedures. Implementing waste to product approach gave economic as well as environmental benefits. This option is possible based on the characteristic of paint waste including toxicity as Lethal Dose 50 and Toxicity Characteristic Leaching Procedure test result. Utilization of paint waste as fuel for boilers is one option, besides the use of paint waste as raw material for making paving blocks.
