Summary: Layered solid particles like h-BN and graphite have been utilized as anisotropic thermo-conductive fillers in polymer composites, but there is a desire for methods to prepare polymer composites with isotropic thermal conductivity. This study successfully prepared epoxy composites with isotropic thermal conductivity using these fillers, achieving solid loadings exceeding 60 vol% and thermal conductivity values of approximately 8 Wm(-1)K(-1) for h-BN/epoxy and 28-29 Wm(-1)K(-1) for graphite/epoxy composites. The internal solid fillers configuration achieved through integration of spherical particles was studied using X-ray diffraction analysis.

Summary: By carbothermal reduction of B2O3 in nitrogen, the surface of graphite can be converted to h-BN, creating a bimaterial system with insulating surface and conductive substrate. The synthesis of this layered material at high temperature and the interface between graphite and h-BN are studied to understand the chemical and mechanical adhesion of the layers. The results show that the thickest h-BN layers with the highest fracture toughness are achieved at a reaction temperature of 1700 degrees C for 18 hours.

Summary: By growing van der Waals-bonded hexagonal boron nitride (hBN) layers on Al2O3 (0001) substrates and depositing MoSx layers via reactive magnetron sputtering, researchers obtain MoSx multilayers with higher crystalline quality on hBN/Al2O3 (0001) compared to bare Al2O3 (0001). The presence of hBN buffer layer enhances surface diffusion, resulting in improved crystallinity of MoSx layers. These findings have implications for nanoelectronic device fabrication.

Summary: A novel molybdenum dioxide/boron nitride heterojunction composite was synthesized using a two-step calcination method, which showed prospective applications in metal corrosion protection. The total impedance values of MoO2/BN-1 and MoO2/BN-2 coatings increased to 314.7% and 163.6%, respectively, compared to an epoxy coating. This increase was attributed to the synergistic effects of physical barrier, electron transport blocking, and photo-induced corrosion protection. These stabilized molybdenum oxide heterojunctions with boron nitride carriers demonstrated feasibility for practical corrosion protection applications.

Summary: The scaling of silicon-based transistors faces challenges such as interface imperfections and gate current leakage at sub-ten-nanometre technology nodes. To achieve smaller channel sizes, less interfacial scattering, and more efficient gate-field penetration, high-mobility two-dimensional layered semiconductors are expected as channel materials. However, progress in 2D electronics is hindered by the lack of a high dielectric constant dielectric with an atomically flat and dangling-bond-free surface.

Summary: 2D boron nitride (BN) and molybdenum disulfide (MoS2) materials have novel chemical, electronic, and optical properties, but recent research has shown potential hazards of MoS2 under certain biological conditions. MoS2 induces dose-dependent cytotoxicity in Kupffer cells (KCs), while the BN derivatives are non-toxic. The toxicity of MoS2 is attributed to nanosheet dissolution and the release of hexavalent Mo, leading to mitochondrial reactive oxygen species generation and apoptosis in KCs. Further, the phagocytosis of MoS2 aggregates triggers a separate response pathway involving lysosomal damage, NLRP3 inflammasome activation, and cytokine production.

Summary: Chirality is a fundamental asymmetry phenomenon observed in chiral optical elements that exhibit asymmetric response to circularly polarized light. Recent developments include nanoplasmonic systems with broken-mirror symmetry and circular dichroism through polarization-contrasting optical absorption. Excitons in atomically thin semiconductors offer an alternative route to circular dichroism through spin-valley polarized excitons. This study demonstrates the transfer of polarization-contrasting optical transitions from excitons in monolayer WSe2 to proximal plasmonic nanodisks through coherent coupling, resulting in magneto-induced circular dichroism. This research highlights the potential of exciton-plasmon interfaces for applications in information processing, nonlinear optics, and sensing.

Summary: In this study, two thermal treatment methods were used to successfully generate negatively charged boron vacancies (V (B) (-)) in hexagonal boron nitride with superior spin properties. Both methods improved the signal-to-noise ratio of the optically detected magnetic resonance signal by a factor of 4. Furthermore, the crystal distortion reflected by the zero-field splitting parameter E significantly reduced after irradiation above 650 degrees C. These findings indicate that thermal treatment is an effective method for a V (B) (-) based quantum sensor.

Summary: Monolayer transition metal dichalcogenides (TMDs) have been extensively studied for their optoelectronic properties and applications. However, their light-emitting capability is severely limited by Auger-type exciton-exciton annihilation (EEA) even at moderate exciton densities. Previous studies using oversimplified models underestimated the Auger coefficient. In this work, we accurately determined the Auger coefficient of monolayer WS2 as a function of temperature by considering laser pulse width and spatially inhomogeneous exciton distribution. Our results provide guidance for enhancing the luminescence quantum yield of TMDs.

Summary: Researchers developed a meta-mirror platform to customize the radiative decay rate and polarization correlation of excitons in TMDCs. By altering the optical layout, the radiative decay rate could be reduced by two orders of magnitude and a statistical correlation between emission intensity and spectral line width was observed. This platform shows great potential for tailoring the two-dimensional distributions of lifetime, density, diffusion, and polarization of TMDC excitons in advanced opto-excitonic applications.

Summary: In this study, electrical switching of ferro-rotational domain states in the charge-density-wave phases of nanometre-thick 1T-TaS2 crystals is demonstrated. Despite the lack of coupling between the electric field and the ferroic order due to symmetry mismatch, the electric field drives domain wall propagation, resulting in reversible, durable, and non-volatile isothermal state switching.

Summary: Recently discovered quantum emitters in 2D materials have the potential to revolutionize integrated photonic devices for quantum information. In order to utilize these emitters effectively, it is crucial to achieve indistinguishable emitted photons. This study investigates two-photon interference in hexagonal boron nitride and finds that the emitted photons exhibit a partial indistinguishability of 0.44 +/- 0.11 in a 3-ns time window, with a corrected value of 0.56 +/- 0.11 accounting for imperfect emitter purity. The dephasing time of the emitter is estimated to be approximately 1.5 ns, half the limit set by spontaneous emission, and a visibility greater than 90% could be achieved with current 2D-material photonics and the Purcell effect.

Summary: This work introduces the concept of a mixed-dimensional reconfigurable field effect transistor (RFET) by combining a one-dimensional silicon nanowire with a two-dimensional hexagonal boron nitride (hBN) gate dielectric. The hBN encapsulation improves the device's electrical parameters, reducing hysteresis and increasing the on-off ratio. RFETs have great potential in reducing device count and power consumption, and the concept of mixed-dimensional RFET could further enhance their functionality.

Summary: As an application of cryo-CMOS technology for future quantum computing, this study explores low-frequency noise reduction in a two-dimensional system with a molybdenum disulfide channel sandwiched by hexagonal boron nitride layers. The passivation effect of boron nitride layers significantly reduces low-frequency noise, compared to directly placing the molybdenum disulfide channel on a silicon dioxide substrate and silicon devices. This indicates that the clean interface and protected surface contribute to the strong reduction in noise, making 2D materials suitable for cryo-CMOS technology.

Summary: Transistors made from the 2D antiferromagnetic semiconductor CrPS4 display significant magnetoconductance due to changes in magnetic state induced by an external magnetic field. Through analysis of the transistor behavior with temperature and magnetic field, we identify the microscopic mechanism linking conductance and magnetic state, specifically the carrier mobility and threshold voltage. Near the Neel temperature T-N, the magnetoconductance is caused by an increase in mobility due to the magnetic field reducing spin fluctuation-induced disorder, while at much lower temperatures (T << T-N), the threshold voltage changes, leading to an increase in the density of accumulated electrons with increasing magnetic field at a fixed gate voltage. These phenomena are explained by the predicted shift in the conduction band edge using ab initio calculations. Our findings demonstrate the dependence of CrPS4's band structure on its magnetic state and reveal a previously unidentified mechanism for magnetoconductance.

Summary: Using Ultrasonic Force Microscopy (UFM), researchers have quantified the variation of out-of-plane Young's modulus in minimally twisted double bilayer graphene (TDBG). They found a softening of the Young's modulus by 7% and 17% along single and double domain walls, respectively. This study highlights the tunability of nanomechanical properties in engineered twisted materials and opens new possibilities for future applications of designer 2D nanomechanical systems.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
