Extreme UV (EUV) lithography is entering full-scale production of high-end IC chips. This transition gives researchers in academia and industry ample motivation to propose new chemistries that will contribute to alleviating the resolution-line edge roughness-sensitivity trade-off dilemma of EUV lithography. We also have a great interest in the radical chemistry of carbon-fluorine bonds working under EUV and have explored its applicability as a platform for implementing novel EUV resists. While it was checked that the chemical concept is viable by using fluorinated small molecules and polymers, it needed to be upgraded in terms of patterning resolution and sensitivity. Recently, we extended successfully the radical-based strategy to the tin-oxo nano cluster resist concept. Soluble fluorinated tin-oxo clusters could be prepared, and they were cast into thin films from a fluorous solution. When the thin film was exposed to EUV radiation, it lost solubility, resulting in the formation of negative-tone images. Under an EUV lithographic condition, the thin film could be tailored down to 10 nm or smaller sized features. In addition, their unique solubility in chemically orthogonal solvents also enabled the build-up of a bilayer structure composed of a non-fluorinated reactive polymer underlayer without curing. The stacked film structure was found to be helpful for the sensitivity improvement. These results propose another interesting EUV resist candidate possessing unique capabilities in thin film processing. © COPYRIGHT SPIE.

In the field of chemical synthesis planning, the accurate recommendation of reaction conditions is essential for achieving successful outcomes. This work introduces an innovative deep learning approach designed to address the complex task of predicting appropriate reagents, solvents, and reaction temperatures for chemical reactions. Our proposed methodology combines a multi-label classification model with a ranking model to offer tailored reaction condition recommendations based on relevance scores derived from anticipated product yields. To tackle the challenge of limited data for unfavorable reaction contexts, we employed the technique of hard negative sampling to generate reaction conditions that might be mistakenly classified as suitable, forcing the model to refine its decision boundaries, especially in challenging cases. Our developed model excels in proposing conditions where an exact match to the recorded solvents and reagents is found within the top-10 predictions 73% of the time. It also predicts temperatures within ± 20 ^∘C of the recorded temperature in 89% of test cases. Notably, the model demonstrates its capacity to recommend multiple viable reaction conditions, with accuracy varying based on the availability of condition records associated with each reaction. What sets this model apart is its ability to suggest alternative reaction conditions beyond the constraints of the dataset. This underscores its potential to inspire innovative approaches in chemical research, presenting a compelling opportunity for advancing chemical synthesis planning and elevating the field of reaction engineering. Scientific contribution: The combination of multi-label classification and ranking models provides tailored recommendations for reaction conditions based on the reaction yields. A novel approach is presented to address the issue of data scarcity in negative reaction conditions through data augmentation. Graphical Abstract: [Figure not available: see fullt

Of the most common, hypoxia, overexpressed glutathione (GSH), and insufficient H2O2 concentration in the tumor microenvironment (TME) are the main barriers to the advancment of reactive oxygen species (ROS) mediated Xdynamic therapies (X = photo, chemodynamic, chemo). Maximizing Fenton catalytic efficiency is crucial in chemodynamic therapy (CDT), yet endogenous H2O2 levels are not sufficient to attain better anticancer efficacy. Specifically, there is a need to amplify Fenton reactivity within tumors, leveraging the unique attributes of the TME. Herein, for the first time, we design RuxCu1-xO2-Ce6/CPT (RCpCCPT) anticancer nanoagent for TME-mediated synergistic therapy based on heterogeneous Ru-Cu peroxide nanodots (RuxCu1-xO2 NDs) and chlorine e6 (Ce6), loaded with ROS-responsive thioketal (TK) linked-camptothecin (CPT). The Ru-Cu peroxide NDs (RCp NDs, x = 0.50) possess the highest oxygen vacancy (OV) density, which grants them the potential to form massive Lewis’s acid sites for peroxide adsorption, while the dispersibility and targetability of the NDs were improved via surface modification using hyaluronic acid (HA). In TME, RCpCCPT degrades, releasing H2O2, Ru2+/3+, and Cu+/2+ ions, which cooperatively facilitate hydroxyl radical (•OH) formation and deactivate antioxidant GSH enzymes through a cocatalytic loop, resulting in excellent tumor therapeutic efficacy. Furthermore, when combined with laser treatment, RCpCCPT produces singlet oxygen (1O2) for PDT, which induces cell apoptosis at tumor sites. Following ROS generation, the TK linkage is disrupted, releasing up to 92% of the CPT within 48 h. In vitro investigations showed that laser-treated RCpCCPT caused 81.5% cell death from PDT/CDT and chemotherapy (CT). RCpCCPT in cancer cells produces red-blue emission in images of cells taking them in, which allows for fluorescence image-guided Xdynamic treatment. The overall results show that RCp NDs and RCpCCPT are more biocompatible and have excellent Xdynamic the

Antioxidants are critical for protecting the body from the oxidative stress caused by free radicals . These chemicals, which scavenge radicals and are frequently obtained from foods such as fruits, vegetables, and herbs, are extremely important for overall health. Backhousia citriodora produces an essential oil that is notable for its abundance of bioactive components, which greatly add to its advantageous qualities. The purpose of this study was to investigate the chemical composition of the essential oil extracted from B. citriodora leaves, with an emphasis on the oil's potential as an antioxidant. Employing ultrasonic-assisted extraction, this research identified geranial (23.2 %) and neral (19.7 %) as the predominant bioactive constituents through gas chromatography-mass spectrometry analysis. These compounds exhibited notable antioxidant capabilities, as evidenced by the extract's substantial TPC of 134.72 mg GAE/g, underscoring its abundance in phenolic compounds . Evaluation of DPPH and ABTS radical scavenging activities further highlighted B. citriodora leaf extract robust antioxidant efficacy, demonstrating compelling IC 50 values of 2.59 ± 0.532 µg/mL and 34.53 ± 1.14 mg/mL, respectively. These findings underscore the potential of B. citriodora as a natural antioxidant resource with promising applications in pharmaceuticals, cosmeceuticals , and food industries.
