Unraveling the Interfacial Carrier Behavior in PtSe2-MoSe2 Heterostructures: Insights from Combined Pump-Probe Spectroscopy and Scanning Tunneling Microscopy.

Interfacial carrier behavior is vital for modifying the optoelectronic performance of 2D materials with atomical thickness, yet understanding exciton dynamics within hetero-phase heterojunctions at the nanoscale remains elusive. Here, carrier dynamics at the interface in molecular beam epitaxy grown 1T PtSe2-1H MoSe2 heterostructures are revealed by ultrafast pump-probe spectroscopy, and the corresponding mechanisms are studied by combining scanning tunneling microscopy/spectroscopy (STM/STS). The difference in exciton lifetimes and signal intensities in the heterostructures at the energies larger and narrower than the bandgap of MoSe2 demonstrates both electrons and holes transfer at the interface of PtSe2 and MoSe2 monolayers. Such bipolar transfer is interpreted through both the type-I (lateral) and type-II (vertical) band alignments revealed by STS measurements across the heterojunctions interface. Besides, it also shows that the band alignment modification of in-plane heterojunctions by a specific conductive substrate can fairly alter the exciton dynamics at the interface. This work provides a comprehensive insight into the carrier dynamics in PtSe2-MoSe2 heterostructures with high spatial and temporal resolutions and may be beneficial for their design in optoelectronic devices.

From Dry to Wet, the Nature Inspired Strong Attachment Surfaces and Their Medical Applications.

Strong attachment in complicated human body environments is of great importance for precision medicine especially with the rapid growth of minimal invasive surgery and flexible electronics. Natural organisms with highly evolved feet or claws can easily climb in complex environments from dry to wet and even underwater, providing significant inspiration for strong attachment research. This review summarizes the strong attachment behaviors of natural creatures in varied environments such as the gecko, tree frog, and octopus. Their attachment surfaces' complex micronano structures and material properties exhibit evolutionary adaptations that enable them to transition across dry, wet, and underwater environments, highlighting the intricate mechanism of interfacial micronano dynamic behaviors. The interfacial liquid/air media regulation and contact stress adjustment from the coupling effects of surface structures and materials have been concluded as key factors in natural strong attachments. With the bioinspired strong attachment surface design, manufacturing methods including mold-assisted replication, nano 3D printing, self-assembly and field induced molding have been discussed. Finally, applications of bioinspired surfaces in low damage surgical instruments, tissue repair and flexible electronics have been demonstrated.

Interfacial Bond Behavior of Clay Brick Masonry Strengthened with CFRP

This study investigates the interfacial bond behavior of clay brick masonry strengthened with carbon fiber-reinforced polymer (CFRP) through single-side shear tests. Two specimen types (single bricks and masonry prisms) were tested under varying parameters, including bond length, bond width, mortar joints, and end anchorage. Experimental results revealed cohesive failure within the masonry substrate as the dominant failure mode. Mortar joints reduced bond strength by 12.1–24.6% and disrupted stress distribution, leading to discontinuous load–displacement curves and multiple strain peaks in CFRP sheets. Increasing bond width enhanced bond capacity by 16.3–75.4%, with greater improvements observed in single bricks compared with prisms. Bond capacity initially increased with bond length but plateaued (≤10% increase) beyond the effective bond length threshold. End anchorage provided limited enhancement (<14%). A semi-theoretical model incorporating a brick–mortar area proportion coefficient (χ) and energy release rate was proposed, demonstrating close alignment with experimental results. The findings highlight the critical influence of mortar joints and provide a refined framework for predicting interfacial bond strength in CFRP-reinforced masonry systems.

Electrolyte Chemistry Modulation Toward High-Performance and Ultralow-Temperature Silicon Anode.

The high-capacity silicon (Si) anode usually suffers from rapid capacity decay and low Coulombic efficiency in carbonate electrolytes resulting from large volume expansion and unstable solid electrolyte interphase (SEI). In addition, the sluggish electrode kinetics in routine electrolytes at subzero temperatures severely hampers the operational capabilities of Si-based batteries. Herein, a rational electrolyte design strategy is reported to tune the solvation chemistry and interfacial behavior of the electrolyte for high-performance Si anode. The interfacial stability and electrochemical reaction kinetics can be enhanced simultaneously at both room temperature and ultralow temperature by combining two kinds of ether-based solvents (cyclopentylmethyl ether and tetrahydrofuran), which enables high cation conductivity, low Li-ion desolvation barrier, and formation of a robust LiF-elastic polymer SEI. Consequently, the optimized electrolyte extends the cyclability of the Si anode, maintaining more than 80% capacity retention over 200 cycles at -20 and -35°C. Even at -40°C, the Si electrode still delivers a high reversible capacity of 2157.0 mAh g-1, showing the highest capacity retention of 68.5% up to date relative to its room-temperature capacity. Moreover, the assembled full cells Si||LiFePO4 and Si||LiNi0.8Co0.1Mn0.1O2 demonstrate excellent electrochemical performance with no capacity degradation over 180 and 120 cycles, respectively, at -20°C.

Experimental and theoretical investigations into structural, morphological and optical characters of the Al2O3, CuO and ZnO-based nanofluids for interfacial tension reduction

This research elucidates interfacial tension behavior of nanofluid of Al2O3, CuO and ZnO. The synthesis was facilitated by sol gel method. The features are elaborated by employing SEM, XRD and RAMAN. The soft of CASTEP Material studio was considered to simulate energy band gap, partial density of states and dielectric constant. The interfacial tension analysis was conducted by placing crude oil. The outcomes reveal that dielectric behaviour along with interfacial tension significantly varies across the nanofluids. The extravagant performance of ZnO-based nanofluid is witnessed in comparison to other contemporaries. This extent of decrement remained 11.3% using ZnO-based nanofluid.

Interfacial Behaviour and Compatibility of Synthetic Oil Based Mud with Ionic Liquids

Waste management is a sustainable development issue globally as valuable materials that are yet to be discovered are limited by waste treatment infrastructure. Drilling wastes are toxic due to heavy metals and hydrocarbons in the mixture, thus categorised as hazardous. Novel options must be investigated to explore the recovery of the hydrocarbons despite other established treatment methods. Hence, this study investigates the interfacial behaviour and compatibility of unused drilling fluid in the synthesised 1-propyl-3-methylimidazolium bromide ionic liquid (propyIMIMBr-IL). The findings reveal that the unused drilling fluid and ionic liquids give a heterogeneous mixture that separates into an upper oil layer and a lower ionic liquid for recovery and characterisation by the Fourier-transformed infrared (FTIR). This recovery of drilling fluid from ionic liquid and drilling fluid simulated mixture is a process that can be advanced during drilling waste management to study the chemical reactions and maximise the recovery potentials of propyIMIMBr-IL.
