Antimony‐Based Halide Perovskite Nanoparticles as Lead‐Free Photocatalysts for Controlled Radical Polymerization
Authors: Zhu Yifan , Zhang Jiahui 
Published: February 2024

AbstractMetal halide perovskites have emerged as versatile photocatalysts to convert solar energy for chemical processes. Perovskite photocatalyzed polymerization draws special attention due to its straightforward synthesis process and the ability to create advanced perovskite‐polymer nanocomposites. Herein, this work employs Cs3Sb2Br9 perovskite nanoparticles (NPs) as a lead‐free photocatalyst for light‐controlled atom transfer radical polymerization (ATRP). Cs3Sb2Br9 NPs exhibit high reduction potential and interact with electronegative bromide initiator with Lewis acid Sb sites, enabling efficient photoinduced reduction of initiators and controlled polymerization under blue light irradiation. Methacrylate monomers with various functional groups are successfully polymerized, and the resulting polymer showcased a dispersity (Đ) as small as 1.27. The living nature of polymerization is confirmed by high chain end fidelity and kinetic studies. Moreover, Cs3Sb2Br9 NPs serve as heterogeneous photocatalysts, demonstrating recyclability and reusability for up to four cycles. This work presents a promising approach to overcome the limitations of lead‐based perovskites in photoinduced controlled radical polymerization, offering a sustainable and efficient alternative for the synthesis of well‐defined polymeric materials.

Published: February 2024

AbstractEffects of carbon nanotubes (CNTs) content and the in situ surface modification via bis(triethoxysilylpropyl) disulfide (Si75) and (3‐aminopropyl) triethoxysilane (KH550) on the rheological properties of rubber nanocomposites are explored. Results from the strain sweep demonstrate that the filler network of the nanocomposite is enhanced when the hydroxylated CNT (HCNT) is incorporated. The promotion of filler–rubber interaction in nanocomposite reinforced with modified CNT is validated by both stress relaxation and strain sweep measurements. The die swell ratio (B) declines with increasing HCNT content and rises with a heightened shear rate. Compared to those without HCNT, B of the nanocomposites, which contained 5 phr HCNT, decreased by 5.4%, 7.0%, and 17.3% at 50, 200, and 500 s−1, respectively. The Si75‐modified HCNT and the carboxylated CNT (CCNT) reduce the B‐value of the extrudates at 500 s−1 by 3.7% and 3.0%, respectively. However, the extrudates filled with KH550‐modified HCNT or CCNT showed a larger B due to pre‐crosslinking, as demonstrated by stress relaxation and swelling tests. Furthermore, it is also found that the application of KH550 has an acceleration effect on the curing reaction, increasing the curing efficiency by 8.5%.Highlights
The promotion of filler–rubber interaction is validated by RPA.
The dimensional stability of the composites is improved after incorporating CNT.
The extrudates with Si75 exhibit a reduced B and improved surface morphology.
CNT content increase raises MH, ML, and shortens the t10 of the composite.

Deep learning for drug‐drug interaction prediction: A comprehensive review
Authors: Li Xinyue , Xiong Zhankun , Zhang Wen , Liu Shichao 
Published: February 2024

AbstractThe prediction of drug‐drug interactions (DDIs) is a crucial task for drug safety research, and identifying potential DDIs helps us to explore the mechanism behind combinatorial therapy. Traditional wet chemical experiments for DDI are cumbersome and time‐consuming, and are too small in scale, limiting the efficiency of DDI predictions. Therefore, it is particularly crucial to develop improved computational methods for detecting drug interactions. With the development of deep learning, several computational models based on deep learning have been proposed for DDI prediction. In this review, we summarized the high‐quality DDI prediction methods based on deep learning in recent years, and divided them into four categories: neural network‐based methods, graph neural network‐based methods, knowledge graph‐based methods, and multimodal‐based methods. Furthermore, we discuss the challenges of existing methods and future potential perspectives. This review reveals that deep learning can significantly improve DDI prediction performance compared to traditional machine learning. Deep learning models can scale to large‐scale datasets and accept multiple data types as input, thus making DDI predictions more efficient and accurate.

AbstractQuantum chemistry calculations were performed to elucidate the reaction sites and degradation routes of dexamethasone. Flow Injection Analysis Electrospray Fourier‐Transform Ion Cyclotron Resonance Mass Spectrometry (FIA‐ESI‐FTCIR‐MS) was used to identify dexamethasone and its byproducts in Mexico City's wastewater, guided by results from ab‐initio calculations on the bond energy analysis and thus propose possible degradation routes. Products of hydroxylation/reduction, decarbonylation/formylation and defluorination reactions were identified. The results of this study contribute to the identification of the degradation products of drugs commonly used in the treatment of COVID‐19 in urban areas. Through wastewater analysis and computationally assisted Mass‐Spectrometry techniques, an alternative approach is presented to identify byproducts in complex matrices when analytical standards are unavailable or in case of limited understanding on the stability of the degradation byproducts in aqueous medium.

Published: February 2024

AbstractA set of three copper(II) complexes C28H24CuN4O2 [CuL1], C24H22CuN4O [CuL2] and C26H22CuN4O [CuL3] incorporated with ligands 1‐benzyl‐1H‐indazol‐3‐ol, 2,2′‐bipyridyl and 1,10‐phenanthroline have been synthesized, characterized and subjected for biomedical applications. New copper(II) derivatives were characterized by FTIR, EPR and HRMS spectral tools. Cyclic voltammograms were recorded to ascertain redox potential and UV‐Vis and Fluorometer were employed to establish photophysical properties of all the new copper(II) complexes. Further, these derivatives of Cu(II) were subjected for DNA and BSA binding studies by using absorption‐emission spectral methods and viscosity measurements as well as by molecular docking. DFT studies of the above‐mentioned derivatives suggested square planar geometry along with other relevant molecular investigations. Eventually, these new Cu(II) complexes have been tested with DPPH and MTT assay to determine the cytotoxicity against MCF7 cell lines to observe remarkable potency with IC50 values 80.68 μg/ml, 49.40 μg/ml and 45.91 μg/ml, respectively.

Regulation Dipole Moments of N‐Doped Graphene Coordinated with FePc Toward Highly Efficient Microwave Absorption Performance in C Band

Published: February 2024

AbstractThe development of composites with highly efficient microwave absorption (MA) performance deeply depends on polarization loss, which can be induced by charge redistribution. Considering the fact that polarization centers can be easily obtained in graphene, herein, iron phthalocyanine (FePc) is used as polarization site to coordinate with nitrogen‐doped graphene (FePc/N‐rGO) to optimize MA performance comprehensively. The factors influencing MA properties focus on the interaction between FePc and N‐rGO, and the change of dipole moments. The density functional theory (DFT) results demonstrated that FePc has strong interaction with N defect sites in graphene. The charge loss for FePc and charge accumulation for N‐rGO occurred, leading to great increase of dipole moment, and the increased dipole moment can be acted as a descriptor to evaluate the enhanced polarization loss. Due to high charge redistribution capacity of N defect sites and FePc polarization centers, the FePc/N‐rGO showed excellent MA properties in C band, and the minimum reflection loss value can reach −49.3 dB at 5.4 GHz with thickness of 3.8 mm. In addition, the fabric loaded with FePc/N‐rGO showed good heat dissipation property. This work opens the door to the development of MA performance bound to polarization site with dipole moment.

Published: February 2024

AbstractPhotocatalytic oxidative coupling of CH4 (OCM) is a promising CH4 conversion process that can achieve efficient methane conversion with the assistance of O2. It remains to be highly challenging to improve the photocatalytic OCM activity from catalyst design and to deepen the understanding of the reactant activation in the OCM process. In this work, the Au‐loaded ZnAl‐layered double hydroxides (LDHs) with and without oxygen vacancy are constructed (denoted as Au/ZnAl and Au/ZnAl‐v), respectively. When applied for photocatalytic OCM, the Au/ZnAl‐v shows a CH4 conversion rate of 8.5 mmol g−1 h−1 with 92% selectivity of C2H6 at 40 °C, outperforming most reported photocatalytic OCM systems at low temperature reported in the literature. Furthermore, the catalytic performance of Au/ZnAl‐v can be stable for 100 h. In contrast, the An/ZnAl exhibits a CH4 conversion rate of 0.8 mmol g−1 h−1 with 46% selectivity of C2H6. Detailed characterizations and DFT calculation studies reveal that the introduced Ov sites on Au/ZnAl‐v are able to activate O2, and the resulting superoxide radical O2·− greatly promotes the activation of CH4. The coupling of CH3· groups with the assistance of Au cocatalyst leads to the formation of C2H6 with high photocatalytic activity.
Towards a more equitable ELT practice: Practicing queer inquiry in Thailand's university language classrooms
Authors: Ulla Mark B. , Paiz Joshua M. 
Published: February 2024

AbstractDespite the sustained focus towards inclusive language teaching and queer pedagogy in Teaching English to Speakers of Other Languages (TESOL) and language education in recent years, employing an inclusive pedagogical practice and having language teaching resources that respect the gender identity among lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA+) students remain a challenge in many English language teaching (ELT) classrooms throughout the world. Employing an auto‐ethnomethodological approach, in this article the authors present their teaching practice experience in an attempt to queer their ELT classroom and provide a safe space for all gender identities in learning the language through a queer‐informed language teaching framework in an ELT classroom at a university in Thailand. It is the goal of this inquiry to add to the empirical evidence for gender inclusivity in an ELT classroom. Additionally, this study offers language practitioners consideration for having a queer‐informed classroom where there is diversity, inclusion, and engagement and where students are free to discuss their sexual identities, adding to the growing influence of gender perspective and inclusivity in heteronormative language education.

Published: February 2024

AbstractIn this work, we present a novel error analysis for fractional Carathéodory type differential equations with time irregular coefficients. It is based on the filtered probability space, with Banach spaces and then discretized using the randomized numerical method, which is a prototype derived from the Monte Carlo method. We derive error estimates where these estimates also under the low regularity that the function is not assumed to be differentiable. The convergence order is also studied. Finally, we present numerical examples that validate the theoretical conclusions, as well as to highlight the usefulness of our technique and the accuracy of error analysis.

Dryland Ecosystem Services and Human Wellbeing in a Changing Environment and Society
Authors: Lu Nan , Yu Dandan , Zhang Lu , Lu Yihe , Fu Bojie 
Published: February 2024

AbstractThe framework of the Global Dryland Ecosystem Programme (Global-DEP) combines the ecosystem service (ES) research paradigm and system dynamics thinking. The core of the framework is the resilience of social-ecological systems (SESs) in drylands. This resilience depends on the interaction between ecological and social subsystems. Water shortages, desertification, and poverty are currently the biggest challenges to maintaining resilience and realizing sustainable development in dryland SESs. However, the internal links between ecosystem degradation/restoration and poverty/eradication remain unclear. ESs bridge ecological and social subsystems by forming a “bonding concept” that connects environmental goals and socioeconomic goals, as ESs can directly or indirectly promote almost all land-related sustainable development goals (SDGs). Clarifying the change of ESs and their contributions to human well-being (HWB) is the key to the entangled dryland challenges, promoting the resilience of SESs and finding solutions to coordinate ecological protection and socioeconomic development. This chapter summarizes the research progress in dryland ES and its relationship with HWB in a changing environment and society. It outlines research priorities, focusing on the concept of ES and how its methodologies contribute to dryland research and management for realizing SDGs. The priorities are as follows: ES quantification; the interactions among ESs; mechanisms of ES contributing to HWB; landscape optimization for ESs; and ecological compensation.
Antibiofilm and antivirulence activities of laminarin-gold nanoparticles in standard and host-mimicking media
Authors: Tabassum Nazia , Khan Fazlurrahman , Jeong Geum-Jae , Oh Dokyung , Kim Young-Mog 
Published: February 2024

Abstract
The rapidly rising antimicrobial resistance (AMR) in pathogenic bacteria has become one of the most serious public health challenges, with a high death rate. Most pathogenic bacteria have been recognized as a source of AMR and a primary barrier to antimicrobial treatment failure due to the development of biofilms and the production of virulence factors. In this work, nanotechnology was employed as a substitute method to control the formation of biofilms and attenuate virulence features in Pseudomonas aeruginosa and Staphylococcus aureus. We synthesized biocompatible gold nanoparticles from marine-derived laminarin as potential biofilm and virulence treatments. Laminarin-gold nanoparticles (Lam-AuNPs) have been identified as spherical, 49.84 ± 7.32 nm in size and − 26.49 ± 1.29 mV zeta potential. The MIC value of Lam-AuNPs against several drug-resistant microbial pathogens varied from 2 to 1024 μg/mL in both standard and host-mimicking media. Sub-MIC values of Lam-AuNPs were reported to effectively reduce the production of P. aeruginosa and S. aureus biofilms in both standard and host-mimicking growth media. Furthermore, the sub-MIC of Lam-AuNPs strongly reduced hemolysis, pyocyanin, pyoverdine, protease, and several forms of flagellar and pili-mediated motility in P. aeruginosa. Lam-AuNPs also inhibited S. aureus hemolysis and the production of amyloid fibrils. The Lam-AuNPs strongly dispersed the preformed mature biofilm of these pathogens in a dose-dependent manner. The Lam-AuNPs would be considered an alternative antibiofilm and antivirulence agent to control P. aeruginosa and S. aureus infections.

Key points
• Lam-AuNPs were biosynthesized to control biofilm and virulence.
• Lam-AuNPs show effective biofilm inhibition in standard and host-mimicking media.
• Lam-AuNPs suppress various virulence factors of P. aeruginosa and S. aureus.
Antimicrobial resistance in aeromonads and new therapies targeting quorum sensing

Published: February 2024

Abstract
Aeromonas species (spp.) are well-known fish pathogens, several of which have been recognized as emerging human pathogens. The organism is capable of causing a wide spectrum of diseases in humans, ranging from gastroenteritis, wound infections, and septicemia to devastating necrotizing fasciitis. The systemic form of infection is often fatal, particularly in patients with underlying chronic diseases. Indeed, recent trends demonstrate rising numbers of hospital-acquired Aeromonas infections, especially in immuno-compromised individuals. Additionally, Aeromonas-associated antibiotic resistance is an increasing challenge in combating both fish and human infections. The acquisition of antibiotic resistance is related to Aeromonas’ innate transformative properties including its ability to share plasmids and integron-related gene cassettes between species and with the environment. As a result, alternatives to antibiotic treatments are desperately needed. In that vein, many treatments have been proposed and studied extensively in the fish-farming industry, including treatments that target Aeromonas quorum sensing. In this review, we discuss current strategies targeting quorum sensing inhibition and propose that such studies empower the development of novel chemotherapeutic approaches to combat drug-resistant Aeromonas spp. infections in humans.

Key points
• Aeromonas notoriously acquires and maintains antimicrobial resistance, making treatment options limited.
• Quorum sensing is an essential virulence mechanism in Aeromonas infections.
• Inhibiting quorum sensing can be an effective strategy in combating Aeromonas infections in animals and humans.

AbstractTumor immunotherapy is booming around the world. However, strategies to activate the immune system and alleviate the immunosuppression still need to be refined. Here, we demonstrate for the first time that low-intensity pulsed ultrasound (LIPUS, spatial average time average intensity (Isata) is 200 mW/cm2, frequency is 0.3 MHz, repetition frequency is 1 kHz, and duty cycle is 20%) triggers the immune system and further reverses the immunosuppressive state in the mouse models of breast cancer by irradiating the spleen of mice. LIPUS inhibited tumor growth and extended survival in mice with 4 T-1 tumors. Further studies had previously shown that LIPUS enhanced the activation of CD4+ and CD8+ T cells in the spleen and led to significant changes in cytokines, as well as induced upregulation of mRNA levels involved in multiple immune regulatory pathways in the spleen. In addition, LIPUS promoted tumor-infiltrating lymphocyte accumulation and CD8+ T cell activation and improved the dynamics of cytokines/chemokines in the tumor microenvironment, resulting in a reversal of the immunosuppressive state of the tumor microenvironment. These results suggest a novel approach to activate the immune response by irradiating the spleen with LIPUS.
