In this paper, we develop a novel approach to achieve ultra-high resolution in organic light-emitting diodes (OLEDs) through a photolithography patterning process. It is important to apply a solvent resistant electron transport layer (ETL) in the photolithography pattering of OLED because of solution coating process of photoresist on the ETL. Therefore, a solvent resistant ETL named 2,7-bis(4,6-diphenyl-1,3,5-triazin-2-yl)-9,9′-spirobi[fluorene] (SBF-Trz) was developed and employed as the ETL of OLEDs. The SBF-Trz demonstrated excellent solvent resistance during photolithography process and enabled device performances comparable to those of the conventional OLED without any photolithography process. It was found that the SBF-Trz ETL is appropriate as the ETL of the OLED patterned by photolithography due to good electron transport property, good stability, and good solvent resistance. © 2024, John Wiley and Sons Inc.

This study investigated the effects of natural rubber(NR)and an organic peroxide on the rheological properties,mechanical properties,morphology,and bubble stability during film blowing of poly(lactic acid)(PLA).The NR and peroxide contents were varied from 0 wt%to 25 wt%and 0 wt%to 0.5 wt%,*** results confirmed that the presence of well-dispersed NR could significantly improve the toughness,elongation at break,and processability of PLA films,where the optimal amount of NR was 15 wt%.For the reactive blending with peroxide,a suitable peroxide content for good film toughness and clarity was 0.03 wt%,while the higher content of 0.1 wt%could provide slightly higher *** contents are considered much lower than that in the PLA system(without NR),which required up to 0.5 wt%*** rheological studies indicated that the melt strength,the storage modulus(G’)and complex viscosity(η*)at low frequency could be correlated with good film blowing processability of the PLA/NR films at low gel *** parameters failed to correlate in the films having high gel contents as the deformation rate experienced by each test was different leading to the different levels of response to the type and amount of gels.

Fuel cells (FCs) are considered as the next generation of energy power sources with various feedstocks like hydrogen. Hydrogen FCs, with the combined advantages of hydrogen, are one of the promising renewable sources of energy with zero carbon dioxide emissions and high-power value. Hydrogen for FCs can be produced via water splitting and biobased approaches with their sub-techniques. Although there are many approaches to hydrogen, not all the methods result in green hydrogen. Green materials in FCs can be applied to different components of the membrane electrode assemblies. They are either incorporated within existing commercial grades of electrolytes and electrodes or as substitutes for non-environmentally materials in the form of single matrices or composites. This article presents the various methods for the production of green hydrogen, including water splitting with triggers of electricity, light, biological, and temperature, as well as biochemical and bio thermochemical routes. It also reviews the green materials employed in the various types of FCs, with the possibility of use for hydrogen FCs. © 2024 Hydrogen Energy Publications LLC

This study synthesizes three sequential steps: pretreatment, acid hydrolysis, and enzyme hydrolysis for bioethanol and hydrochar production from macroalga Gracilaria. The Taguchi method is employed separately in each step to optimize relevant operating factors, aiming to maximize the monosaccharide yield. During pretreatment, environmentally friendly alkaline ionized water is utilized as it does not contain chemical additives. Afterward, microwave-assisted hydrolysis is adopted to enhance the monosaccharide yield of the macroalga for bioenergy production. The results show that the total sugar of Gracilaria undergoing acid hydrolysis alone is 28.72 g‧L−1. The total sugar content after alkaline pretreatment followed by acid hydrolysis is 32.64 g‧L−1, and it increases to 34.76 g‧L−1 after adding enzymes. Meanwhile, the higher heating value of Gracilaria increases from 10.884 MJ‧kg−1 to 12.620 MJ‧kg−1 after undergoing alkaline pretreatment. After the acid and enzyme hydrolysis processes, it increases to 15.164 MJ‧kg−1. The solid biofuel's calorific value increases by 39 % from the three-stage processes. The liquid product combined with Saccharomyces cerevisiae can produce bioethanol, while the produced hydrochar can be used as a solid fuel. This research promotes the development of macroalgal biomass for energy and environmental applications, thereby advancing the circular bioeconomy. © 2024 The Institution of chemical Engineers

High numerical aperture (NA) EUV lithography is considered as the most-promising candidate for next generation lithography protocol that will play a crucial role in meeting the demand on the enhanced semiconductor performance and productivity. While this technology enables the fabrication of sub-10 nm patterns, the increased NA has posed challenges, such as reduced depth of focus and narrower process margins. To overcome these hurdles, it is essential to apply thinner resist films while ensuring that the resulting small patterns maintain sufficient physical and chemical durability. Moreover, considering that thinner films absorb fewer photons, the resist molecular structure should be designed to compensate sensitivity burdens. Here, an approach has been proposed to enhance sensitivity by accelerating the solubility change of a well-known tinbased nanocluster resist. To accomplish this goal, it is important to increase not only the number of secondary electrons but also reaction sites and promote radical-based chemical reactions. We aimed at experimentally validating this concept by utilizing elements with high EUV absorbance and highly reactive functional groups with tin radicals. As a model resist, we chose a tin-oxo cage material consisting of a divalent cation containing 12 tin atoms and two counter anions. Our findings indicate that the introduction of unsaturated groups capable of building bridging bonds with radicals leads to fast solubility change at a lower exposure dose, thus enhancing sensitivity. This research offers a promising direction for the development of resists tailored for High NA EUV lithography. © COPYRIGHT SPIE. Downloading of the abstract is permitted for personal use only.

Household bleach products as high-performance and cost-effective cleaning agents for membrane fouling

It has been widely known that polymeric membrane such as polyvinylidene fluoride (PVDF) is very prone to fouling that occurs during the filtration process. In the same light, membrane cleaning has also been popularly used as a mean to remove foulants which accumulated on or inside the membrane. In this paper, the utilization of domestic bleach, which is affordable and easily found in the nearest markets, as the membrane cleaning agent is discussed. The performance evaluation is conducted on three kinds of commercial domestic bleaches, namely Bayclin, Proclin, and Soclin. In order to study deeper about those product potentials, the performance is compared with the pure sodium hypochloride (NaOCl) which has been known as a common chemical cleaning agent, and distillate water. The results show that the bleach products work excellence in cleaning the fouled membrane which confirmed by the scanning electron microscopy (SEM) analysis results, in which membranes cleaned with the bleaches have cleaner surface compared to that cleaned with distillate water. Interestingly, the positive outcome can also be seen in the flux recovery ratio (FRR) of the membranes after cleaning which managed to recover up to 95% of the lost flux. Overall, all three bleach products showed closely similar performance as the original NaOCl, and showed far better performance than distillate water. This result emphasizes that the domestic bleaches are highly promising to be membrane chemical cleaning agents, replacing the common chemicals. This work makes a significant contribution toward giving reasonably priced options for alternative methods of cleaning membranes. © 2023 The Author(s)

The increasing quest for therapeutic alternatives in treating non-communicable chronic diseases like obesity has propelled research into bioactive peptides, with a particular focus on milk due to its rich protein composition and associated health benefits. Milk fermentation, a traditional process in dairy production, enhances the bioactivity of peptides, broadening their potential therapeutic uses. This study investigated the anti-obesity potential of peptides from bovine milk fermented by Lacticaseibacillus casei LBC 237, identifying 143 peptides, notably LGPV and EVPMP. In silico analyses revealed that LGPV and EVPMP biopeptides exhibited significant interactions with target proteins, employing various molecular interactions such as Van der Waals forces, hydrogen bonds, and electrostatic interactions. These peptides shared common binding sites in some enzymes, suggesting a similar mode of interaction between molecule and target protein, akin to key pharmaceuticals recommended for treating these pathologies. Furthermore, amino acid characteristics present in the peptides, including hydrophobic residues like Leucine, Glutamate, Valine, and Proline, proved essential for their bioactive and inhibitory activities. These findings highlight the potential of LGPV and EVPMP biopeptides as therapeutic agents in managing obesity and metabolic disorders. They provide important insights into their mechanisms of action, paving the way for future research to apply them practically in preventing and treating metabolic conditions. © 2024 The Authors
