Synthesis of mixed-dimensional 1D-graphene nanoribbon/2D-CuSe heterostructures with controllable band alignments One- and two-dimensional (1D-2D) heterostructures have drawn growing interest due to their appealing optoelectronic and catalytic properties. Controlling the band alignment of 1D-2D heterostructures is crucial for their large-scale applications, but remains challenging to achieve experimentally. Here, we report a strategy for the atomically precise fabrication of 1D graphene nanoribbon (GNR) homojunctions and a variety of 1D-GNRs/2D-CuSe vertical heterostructures on Cu(111) substrate. By combining scanning tunneling microscopy, non-contact atomic force microscopy characterizations and density functional theory calculations, the entire preparative process is fully visualized. The GNR homojunctions, which bridge the Cu(111) substrate and the semiconducting CuSe monolayer, show a p-n junction characteristic. The hybrid heterostructures display various band alignments, achieved by varying the width and edge topologies of the GNRs, as well as controlling two different semiconducting phases of the CuSe monolayer. This work offers a promising method to precisely synthesize 1D/2D heterostructures with diverse band alignments for applications in high-performance nanodevices.

Quantifying the Influence of Nanosheet Aspect Ratio on Network Morphology and Junction Resistance in Solution-Processed Nanosheet Networks Optimizing solution-processed nanosheet networks for electronic applications requires understanding the relationship between nanosheet dimensions, network morphology, and electrical properties. Here, we fabricate graphene nanosheets with both low- and high-aspect-ratios using liquid-phase exfoliation (LPE) and electrochemical exfoliation (EE), respectively. Spray-coated networks of both nanosheet types display distinct morphological and electrical properties. High-resolution 3D imaging shows that low-aspect-ratio LPE nanosheet networks display a disordered, porous structure with point-like junctions. Conversely, high-aspect-ratio EE graphene forms low-porosity networks with highly aligned nanosheets with large-area conformal junctions. Electrical measurements demonstrate that EE networks achieve lower resistivity and reduced percolation thicknesses due to reduced junction resistances and improved nanosheet alignment. We propose a theoretical model linking nanosheet bending rigidity, aspect ratio, and junction formation, highlighting the critical role of nanosheet flexibility in enabling conformal junctions. Furthermore, by size-selecting both nanosheet types, we measure the dependence of network resistivity on nanosheet thickness. LPE networks show increasing resistivity with thickness, whereas EE networks exhibit decreasing resistivity. We develop a simple model linking these behaviors to point-like and planar junctions respectively and quantify the size-dependence of both nanosheet and junction resistance for both cases. Unexpectedly, data analysis using this model predicts the EE nanosheets to be more conductive than the LPE ones, a fact confirmed by THz spectroscopy. This study establishes the importance of nanosheet aspect ratio and flexibility in governing network morphology and electrical performance. Our findings provide key insights for developing high-performance, solution-processed 2D material networks for future electronic devices.

Current overview of the mechanistic pathways and influence of physicochemical parameters on the microbial synthesis and applications of metallic nanoparticles Microbe-assisted synthesis of metallic nanoparticles (NPs) has carved a niche among different NP generation methods owing to its simplicity, non-toxicity, low energy requirements, and potential scalability. Microorganisms have ability to produce NPs both intracellularly and extracellularly due to the presence of enzymes, proteins, and other biomolecules that can act as reducing and capping agents. However, a complete mechanistic understanding of this biosynthesis remains elusive. Biosynthesis is influenced by a myriad of factors, such as pH, temperature, reactant concentrations, reaction time, and light. The physicochemical factors associated with the synthesis process affect the morphological, biological, and catalytic properties of the NPs produced. This review focuses on the current paradigm and gaps in our understanding of microbial production pathways and the effects of physicochemical factors on the synthesis and application of various types of metallic NPs. The surveyed literature clearly elucidated the effect of these factors on the size, shape, dispersity, surface properties, and the reaction kinetics. The variations in morphological and surface properties were found to affect the performance of NPs in different applications such as catalysis, antimicrobial, and anticancer activities. Understanding the mechanistic pathways and the influence of physicochemical factors on synthesis can be potentially beneficial for the production of NPs with controlled shapes and sizes, tailored for specific applications.

Impact of Chemicals and Processing Treatments on Thermo-Mechanical Recycling of Polyester Textiles The textile industry is among the world's largest, producing an estimated 124 million tonnes of fibres in 2023, with more than half of these being made from virgin polyester. Less than 0.1% of polyester fibres are recycled into new textiles at the end of their lives. Mechanical, thermo-mechanical, and chemical textile-to-textile polyester recycling are all technically possible, but thermo-mechanical recycling is reported to provide the most promising compromise between cost and quality. Myriad chemicals are used in polyester production, and this paper is the first to review the related academic literature to better understand their impact on recyclability. It has been demonstrated that chemicals used during the production and processing of polyester textiles can either provide resistance to, or catalyse, the degradation of polyester during thermo-mechanical recycling processes. However, the effect of combinations of these chemicals on recycling is largely unknown. Limiting, standardising, and transparently reporting the chemicals used during textile production would simplify research and could lead to better quality products after recycling.

This review systematically explores recent advances in the rational design of CDs for combating oxidative stress-related pathologies. Key strategies include heteroatom doping, selection of bioactive precursors, and utilization of sustainable biomaterials. Doping with Se, Fe, or N enhances reactive oxygen/nitrogen species (RONS) scavenging, peroxidase, catalase, or superoxide dismutase like activities, enabling applications in acute kidney injury, ulcerative colitis, and Parkinson's disease. CDs derived from natural compounds inherit intrinsic antioxidant and anti-inflammatory properties, facilitating gut microbiota regulation, diabetic wound healing, and periodontitis treatment. Notably, stimuli-responsive CDs dynamically modulate multi-enzyme activities, preventing RONS overproduction and enabling precise therapy. This work highlights the synergy between structural engineering and bioactivity preservation in CDs, positioning them as next generation nanotherapeutics for inflammatory, infectious, and degenerative diseases.

Preparation and molecular dynamics simulation of natural rubber thermal conductive composites reinforced with boron nitride modified by a hyperbranched coupling agent Abstract The applications of thermal interface material (TIM) based on boron nitride (BN)‐filled polymer composites are often constrained by weak interfacial interactions between BN and the polymer matrix. In this work, the hyperbranched polymer (H‐Si69) was synthesized by polycondensation on the surface of BN using a sulfur‐containing coupling agent. The coupling agent modified BN (g‐BN), and natural rubber (NR)/g‐BN composites were prepared with higher thermal conductivity and mechanical properties. The thermal conductivity (0.665 W/mK), tensile strength (19.78 MPa), and elongation at break (1091.8%) of the NR/g‐BN composites with a 19.6% volume fraction of g‐BN were 44.40%, 15.47%, and 29.56% higher than those of the NR/BN composites, respectively. Furthermore, molecular dynamics (MD) simulation was employed to calculate the binding energy, free volume fraction, solubility parameter, and mechanical properties of the composite system to explore the interfacial enhancement mechanism. The combined results of the experiments and MD simulation indicated that g‐BN exhibits strong interfacial interactions with the NR matrix, significantly improving the mechanical properties and thermal conductivity of the composites. This work provides a method to improve the compatibility of BN within the NR matrix, offering insight for the preparation of TIMs with high thermal conductivity for applications in electronic packaging devices.

Simulation of gas adsorption on single-walled carbon nanotubes This study combined Grand Canonical Monte Carlo molecular simulations with density functional theory calculations to systematically examine the adsorption of N<sub>2</sub>, O<sub>2</sub>, H<sub>2</sub>, CO<sub>2</sub>, and CH<sub>4</sub> on nineteen single-walled carbon-nanotube (SWCNT) architectures. The effects of temperature, pressure, nanotube diameter, chirality, and vacancy defects on adsorption energies and isosteric heats are quantified. Binary N<sub>2</sub>/O<sub>2</sub> separation within a (22,18) SWCNT is modelled by analyzing energy-distribution functions and spatial adsorption fields. Intermolecular interactions are represented with the Universal Force Field and Lennard-Jones potentials. Lower temperatures and higher pressures enhanced adsorption capacity, while adsorption energies and isosteric heats decreased accordingly. Furthermore, smaller-diameter SWCNTs exhibited superior selectivity for air separation. Neglecting electrostatic and hydrogen-bonding terms for non-polar gases is demonstrated to reduce computational cost without sacrificing accuracy. These findings establish a robust framework for rationalizing SWCNT-based adsorbents for gas-separation applications.
