1. Activated carbons derived from polyethylene terephthalate for coin-cell supercapacitor electrodes.
PMID:日期:2023-05-31We successfully prepared activated carbon derived from polyethylene terephthalate (PET) via carbonization and subsequent activation under various conditions and applied it as active material for supercapacitors. In the activation, we used CO for physical activation or KOH for chemical activation and varied the activation temperature from 600 °C to 1,000 °C. We found that CO activation is unsuitable because of insufficient pore formation or low activation yield. Interestingly, PET-derived activated carbon obtained using KOH (PETK) at 700 °C-900 °C exhibited higher specific surface areas than YP50f, which is a commercial activated carbon. Furthermore, some PETKs even displayed a dramatic increase in crystallinity. In particular, the PET-derived activated carbon prepared at 900 °C with KOH (PETK900) had the highest retention rate at a high charge-discharge rate and better durability after 2500 cycles than YP50f. Furthermore, employing the same process that we used with the PET chips, we successfully converted waste PET bottles into activated carbon materials. Waste PET-derived activated carbons exhibited good electrochemical performance as active material for supercapacitors. We thus found chemical activation with KOH to be an appropriate method for manufacturing PET-derived activated carbon and PETKs derived both from PET chips and waste PET have considerable potential for commercial use as active materials for supercapacitors.

2. {"_":"Effects of Ni/AlO catalyst treatment condition on thermocatalytic conversion of spent disposable wipes.","sub":["2","3"]}
PMID:日期:2023-05-17Municipal solid waste (MSW) management is an essential municipal service. Proper waste treatment is an important part of the waste management. Thermocatalytic waste upcycling has recently gained great interest and attention as a method to extract value from waste, which potentially substitutes traditional waste treatment methods. This study aims at demonstrating the potential for thermocatalytic waste upcycling using spent disposable wipes as an MSW surrogate. Two different Ni/AlO catalysts were prepared, treated under two different atmospheres (N and CO). The catalyst treated in N (Ni/AlO-N) exhibited a higher surface metallic Ni site than the catalyst treated in CO (Ni/AlO-CO). The use of the Ni/AlO-N increased the yield of gas pyrolysate and decreased the yield of byproduct (e.g., wax), compared with no catalyst and the Ni/AlO-CO. In particular, the Ni/AlO-N catalyst affected the generation of gaseous hydrogen (H) by increasing the H yield by up to 102% in comparison with the other thermocatalytic systems. The highest H yield obtained with the Ni/AlO-N was attributed to the most surface metallic Ni sites. However, the Ni/AlO-N catalyst led to char having a lower higher heating value than the other catalysts due to its lowest carbon content. The results indicated that the reduction treatment environment for Ni/AlO catalyst influences thermocatalytic conversion product yields of spent disposable wipes, including enhanced H production.

3. Trends in nano-platforms for the treatment of viral infectious diseases.
PMID:日期:2023-03-20Viral diseases have always been a major health issue, from the currently eradicated poliovirus to the still unresolved human immunodeficiency virus, and have since become a recent global threat brought about by the COVID-19 pandemic. Pathogenic viruses easily spread through various means such as contaminated food and water intake, exchange of bodily fluids, or even inhalation of airborne particles mainly due to their miniscule size. Furthermore, viral coats contain virulent proteins which trigger assimilation into target cells on contact through either direct penetration or induction of endocytosis. In some viruses their outer envelope contains masking ligands that create a means of escape from detection of immune cells. To deal with the nanometer size range and biomolecular-based invasion mechanism, nanoparticles are highly suitable for the treatment. The review highlights the progress in nanoparticle technology, particularly viral therapeutics, including therapeutic strategies and existing clinical applications.

4. Performance and cost-benefit analysis of anaerobic moving bed biofilm reactor for pretreatment of textile wastewater.
PMID:日期:2023-03-10Performance of an anaerobic moving bed biofilm reactor (AnMBBR) was evaluated for pretreatment of real textile desizing wastewater at organic loading rate (OLR) of 1±0.05 to 6.3±0.37 kgCOD/m/d. After OLR optimization, the performance of AnMBBR was evaluated for biodegradation of reactive dyes. AnMBBR was operated under a mesophilic temperature range of 30 to 36 °C, while the oxidation-reduction potential (ORP) and pH were in the range of 504 to 594 (-mV) and 6.98 to 7.28, respectively. By increasing the OLR from 1±0.05 to 6.3±0.37 kgCOD/m/d, COD and BOD removal was decreased from 84 to 39% and 89 to 49%, respectively. While the production of biogas was increased from 0.12 to 0.83 L/L·d up to an optimum OLR of 4.9±0.43 kgCOD/m/d. With increase in the dye concentration in the feed, COD, BOD, color removal and biogas production reduced from 56, 63, 70% and 0.65 L/L·d to 34, 43, 41% and 0.08 L/L·d, respectively. Based on the data obtained, a cost-benefit analysis of AnMBBR was also investigated for the pretreatment of real textile desizing wastewater. Cost estimation of anaerobic pretreatment of textile desizing wastewater indicated a net profit of 21.09 million PKR/yr (114,000 €/yr) and a potential payback period of 2.54 years.

5. Biodegradable dexamethasone polymer capsule for long-term release.
5. 可生物降解的地塞米松聚合物胶囊,用于长期释放PMID:日期:2023-02-02We have developed sustained Dex (dexamethasone) capsule implants for sustained local delivery for inflammatory disease treatment. Four different biodegradable polymers were used as capsule materials: polycaprolactone (PCL), poly(lactic acid) (PLA), 90 : 10 poly(lactic-co-glycolide) (PLGA), and 50 : 50 PLGA. The drug release profiles from the four types of capsule were compared and the profiles were fit to a cylindrical reservoir first-order kinetics model. As a result, 50 : 50 PLGA showed the fastest release with the largest permeability and partition coefficient at 0.4909 nm/s and 1.9519, respectively. On the other hand, PCL showed the slowest release with the smallest permeability and partition coefficient at 0.1915 nm/s and 0.8872, respectively. The results indicate that the drug release kinetics are highly correlated with hydrophobicity of the polymer sheet: the more hydrophobic, the slower the drug release kinetics for the hydrophilic drug. The in vitro therapeutic efficacy of the Dex implant was also explored using TNF- stimulated human umbilical vein endothelial cells (HUVECs), showing effective suppression of IL-6 levels with the implant compared to free Dex with minimal toxicity. Overall, this study suggests that the release trend of Dex from implants follows the hydrophobicity of each polymer, and the Dex implant inhibits the IL-6 expression effectively.

6. Recent development of machine learning models for the prediction of drug-drug interactions.
6. 用于药物相互作用预测的机器学习模型的最新进展PMID:日期:2023-02-02Polypharmacy, the co-administration of multiple drugs, has become an area of concern as the elderly population grows and an unexpected infection, such as COVID-19 pandemic, keeps emerging. However, it is very costly and time-consuming to experimentally examine the pharmacological effects of polypharmacy. To address this challenge, machine learning models that predict drug-drug interactions (DDIs) have actively been developed in recent years. In particular, the growing volume of drug datasets and the advances in machine learning have facilitated the model development. In this regard, this review discusses the DDI-predicting machine learning models that have been developed since 2018. Our discussion focuses on dataset sources used to develop the models, featurization approaches of molecular structures and biological information, and types of DDI prediction outcomes from the models. Finally, we make suggestions for research opportunities in this field.

7. Novel measurement method of determining PS nanoplastic concentration via AuNPs aggregation with NaCl.
7. 通过AuNPs与NaCl聚集测定PS纳米塑料浓度的新型测量方法PMID:日期:2022-06-12Microplastics, or nanoplastics fragmented to sizes in the nanoscale, can easily penetrate living organisms as well as human organs, increasing the risk of toxicity. However, it is challenging to obtain the size of nanoplastics using thermal analysis methods such as pyrolysis gas chromatography/mass spectrometry or thermal desorption-gas chromatography/mass spectrometry, which are used to analyze nanoplastics. In this study, the coupling effect due to the aggregation of gold nanoparticles (AuNPs) was used to measure the concentration of polystyrene nanoplastics (PSNPs). Experiments were conducted to measure the concentration of PSNPs using an ultraviolet-visible spectrophotometer using the phenomenon that the color of the colloid changes when AuNPs are aggregated. The differences in absorbance before and after aggregation after the addition of NaCl were measured. As a result of the experiment, when 20 mM NaCl was added to the solution in which AuNPs and PSNPs were dispersed, the difference in absorbance before and after aggregation and the concentration of PSNPs exhibited high linearity. In addition, 350 and 880 nm-sized PSNPs could be distinguished from each other because of their different linearities. The concentration of PSNPs was measured easily and conveniently without requiring a skilled operator, expensive analytical equipment; additionally, the process was not time or labor intensive, and it was shown that particle size can be measured by distinguishing particles of different sizes.

8. Optimization of the wood pellet supply during the continued increase of the renewable energy's proportion in the energy portfolio.
8. 在能源结构中可再生能源比例持续增加的背景下,优化木屑颗粒供应PMID:日期:2022-04-18The share of renewable energy (RE) in the energy portfolio has been increasing steadily during the past decades. While the trend contributes in lowering the emission of greenhouse gases, it presents new challenges in terms of costs and intermittency. This study evaluates enhanced utilization of biomass energy as a viable solution and presents the mathematical framework for evaluating the costs associated with supplying the required amount of wood pellets. The framework addresses the uncertainty in the future price of pellets, as well as variability in the shipping and storage cost with respect to the supplier and type of facility. A case study based on the latest RE plan of the Korean government shows how the costs and net CO emission can change when the biomass energy is used to provide energy during the intermittency caused by the RE technologies. The results of the study suggest that a substantial difference in costs can occur depending on the supply strategy and that the biomass energy has the potential to resolve the intermittency issue while realizing the South Korean RE plan.

9. Epigenome editing and epigenetic gene regulation in disease phenotypes.
9. 疾病表型中的表观基因组编辑与表观遗传基因调控PMID:日期:2022-03-15Proper gene control across space and time is crucial for the seamless execution of various cellular functions. Rapid advancements in genome-wide studies revealed that in addition to genetic mutations, epigenetic modifications also play an important role in cellular processes and disease development. Epigenetic modifications, including DNA methylation and post-translational modifications on histones via methylation, acetylation, phosphorylation, etc., do not alter DNA sequences. Yet, disruptions of the epigenome can still induce gene malfunction, aberrant cell differentiation, proliferation, and apoptosis, resulting in various diseases such as cancer, neurological disorders, and autoimmune diseases. This review describes the association between epigenetic modifications and disease phenotypes, current techniques to perturb epigenome and analyze changes in gene expression, and perspectives on future epigenetic research.

10. Melamine sponge-based copper-organic framework (Cu-CPP) as a multi-functional filter for air purifiers.
10. 三聚氰胺海绵基铜有机框架(Cu-CPP)作为空气净化器的多功能过滤器PMID:日期:2022-02-03COVID-19 has drawn great attention on the necessity for establishing pathogen-free indoor air. This paper offers an insight into the potential application of a multi-purpose filter to remove fine particulates and disinfect pathogens using melamine sponge with a copper-organic framework. In-situ growth dip coating method was applied to coat Cu-based coordination polymer particle (Cu-CPP) on melamine sponge (MS). The integration of Cu-CPPs with high crystallinity and highly active surface area (1,318.1 m/g) enabled Cu-CPP/MS to have an excellent capture rate (99.66%) and an instant disinfection rate of 99.54% for . Electrostatic attraction seemed to play a crucial role in capturing negative-charged pathogens effectively by positive charges on Cu-CPP arising from unbalanced copper ions in Cu-CPP. Disinfection of pathogens was mainly attributed to catalytically active Cu sites. Organic ligand played an important role in bridging and maintaining Cu ions within the framework. This study highlights the design of a new capture-and-disinfection (CDS) air filter system for pathogens using Cu-CPP/MS. It can be applied as a substitute for conventional high-efficiency particulate air (HEPA) filters.
