Summary: Duplexed aptamers (DAs) are aptasensor formats that can simultaneously recognize and signal the concentration of target molecules, consisting of an aptamer and an aptamer complementary element (ACE). However, the tailored development of DAs for a particular target is currently based on trial and error due to limited knowledge about how the ACE sequence affects the final performance of the biosensors.

Summary: The evolution of land plants has resulted in various body plans, and the differences in cross-sectional geometry and tissue pattern of plant axes affect their flexural rigidity, torsional rigidity, and twist-to-bend ratio. By designing artificial cross-sections and using a mathematical model, we were able to calculate the twist-to-bend ratio and observe clustering of similar tissue patterns.

Summary: Using first-principles calculations and theoretical framework, it was found that monolayer molybdenum trioxide has record low thermal conductivity due to soft flexural and in-plane acoustic modes combined with strong bonding anharmonicity. These insights can guide the search for 2D materials with low thermal conductivity and motivate measurements for potential applications in thermoelectricity and thermal protection.

Summary: The main challenge of nucleation theory lies in accurately evaluating the work of formation of a critical embryo in the new phase, which determines the nucleation rate. The capillarity approximation used in Classical Nucleation Theory, which relies on the planar surface tension, is often criticized for its large discrepancies with experimental results.

Summary: The study prepared and evaluated a series of 1,2,3-triazolyl-appended N- and O-heterocycles containing amidine and amidoxime moieties for their antiproliferative activities. Some compounds showed potent growth-inhibitory effects on cervical carcinoma, hepatocellular carcinoma, and colorectal adenocarcinoma, with certain selectivity. Results also indicated that some compounds bind inside the minor groove of DNA and intercalate into RNA.

Summary: The study found that grafted chains can act as nucleating agents to enhance the crystallization ability of polymer nanocomposite systems, while different interactions between chains and fillers significantly affect the segment mobility of free chains and nucleation process. Additionally, an increase in grafted chain content results in higher crystallization rate and crystallinity.

Summary: Thermal barrier coatings (TBCs) applied in gas turbines undergo high-temperature and complex stress environments, leading to sintering. This study investigated the stress-dependent sintering behaviors of porous TBCs and developed a stress-based sintering model. It was observed that stress gradient induced non-linear differential sintering behavior, and a high-throughput method for stress dependence characterization was proposed. The understanding of stress-dependent sintering behavior can provide guidance for the design and failure analysis of TBCs in complex shaped components in gas turbines' hot section.

Summary: Eukaryotic genomes contain pyrimidine-purine rich regions that can form varied DNA conformations, including triple-stranded structures. These structures have therapeutic and nanotechnological applications, emphasizing the importance of understanding their formation. Study on triplex structures in BOLF1 gene of human herpesvirus 4 revealed intramolecular triplexes are more stable than intermolecular ones, contributing to our knowledge about DNA triple helical structures.

Summary: This study successfully demonstrates the merging and exfoliation of HiPCO single-walled nanotube bundles to form carbon nanoscrolls (CNS) through wet oxidation, HCl washing, and annealing. The beautiful manifestation of CNS through the curling and folding of graphene sheets is observed in the post-treated sample. By utilizing Fourier transform infrared (FTIR), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM) studies, direct evidence of CNS emergence from SWNTs via synthesis of graphene sheets is reported for the first time.

Summary: This study proposes a finite element formulation to investigate the bending, thermal vibration, and buckling behavior of a modified couple stress-based micro-plate under partial piezoelectric excitation. A parameter study is conducted to analyze the effects of different parameters on the nonlinear behavior of micro-plates. The model accuracy is validated by comparing the results with those reported in the literature.

Summary: In this study, nanoscale thin-film boiling on different surfaces was simulated, and it was found that the heat transfer performance of boiling depends on the surface properties. Rough structures improve the efficiency of boiling, while hydrophobic surfaces lead to heat transfer deterioration. The underlying mechanism is attributed to the variation of interfacial thermal resistance.

Summary: The field of ion transport through carbon nanotubes is characterized by varying reported values and uncertainties regarding channel and access resistances. By comparing experimental data with nanofluidic models, it is possible to determine the conditions under which different resistances predominate in CNTs. Most experimental conductance values can be explained by considering variations in slip length and surface charge density, but a few exceptionally high values cannot be accounted for even with extreme parameter values. Improving existing models and enhancing the statistical reliability of experimental data are important for the advancement of research in this field.

Summary: Ultra-efficient transport of water and ions at the nanoscale is studied through molecular dynamics simulations. Carbon nanotubes are used as nanofluidic devices, and the transport of solvated ions inside the nanotubes is found to be dependent on the geometric parameters of the carbon structure and the water models used.

Summary: In cell membranes, submicrometric nanodomains composed of proteins and lipids play important roles in specific functions. However, the detailed morphology of these nanodomains remains unknown. This study combines analytical calculations and Monte Carlo simulations to show that increasing protein concentration results in the elongation of membrane nanodomains. The findings suggest that protein abundance can modulate nanodomain shape and potentially impact their biological function.

Summary: The recent study on the dielectric constant of water confined in nanometric slit pores sheds light on the interplay between different physical mechanisms for ion partitioning in nanopores. The role of the Born contribution in inducing ionic liquid-vapor phase separation is explored, showing that the abrupt change in the dielectric contribution of the potential of mean force with Debye-Huckel screening parameters favors this transition. By establishing phase diagrams and monitoring osmotic pressure, the study reveals the competition between exclusion effects and electrostatic attraction in charged nanopores, providing insights for experiments and simulations on ionic transport through nanopores.
