Quantum Osteoimmunology: A Paradigm Shift in Understanding and Influencing Bone-Immune Crosstalk.

Despite significant advancesin osteoimmunology, the mechanistic underpinnings of immune-skeletal crosstalk remain insufficiently characterized, particularly at the molecular and submolecular scales. The present article introduces quantum osteoimmunology as a novel field of research exploring how quantum mechanical phenomena, such as coherence, tunneling, entanglement, and wavefunction superposition, may influence osteoimmune signaling dynamics. It argues that the current deterministic, temporally linear models of immune activation may overlook the probabilistic and non-linear nature of molecular events governed by quantum principles.

Metamaterial-Enhanced Solar-Driven Processes for Energy Conversion and Water Treatment.

To address global challenges in sustainable energy and water treatment, metamaterials have emerged as a transformative class of materials for solar-driven photocatalysis. Through nanoscale engineering, these artificially structured materials enable precise manipulation of light-matter interactions and significantly enhance solar energy utilization beyond the limits of conventional photocatalysts. This review systematically summarizes recent progress in applying metamaterials to solar-driven processes for energy conversion and water treatment, including photocatalytic CO reduction, water splitting for hydrogen generation, degradation of organic pollutants, and solar-driven water evaporation for purification.

Ferroelectric Tailorable WS/Graphene Phototransistors.

Two-dimensional (2D) phototransistors face severe challenges in achieving high photoresponsivity and low power consumption, primarily due to their low absorption cross-section and short carrier lifetime, especially as the device feature size continues to shrink. To address these challenges, we propose a ferroelectric-enhanced doping effect to conduct band engineering and charge redistribution, which effectively mitigates the Fermi level pinning effect and enables selective ambipolar behaviors, resulting in ideal electrical contact and efficient carrier transport. Furthermore, the polarization-induced floating gate introduces additional gain mechanisms through defect engineering and a tunneling effect, which significantly improves photomultiplication and carrier acceleration.

Altering their natural arrangement, through artificial heterostructures, strain and pressure engineering, chemical doping, intercalation, and alloying, can impart them with unusual optical properties and potentially enhance their performance in various applications. Among these approaches, alloying is generally difficult to control and disrupts the well-ordered homophilic crystal phase of these 2D crystals, albeit with the capability to control materials as thin as a single atomic layer.

LiCoO cathode surface modification with optimally structured LiPO for outstanding high-voltage cycling performance.

While researchers often adopt a higher operating voltage to further enlarge the actual specific capacity of LCO to expand its application scope and market share, this triggers some more intractable issues in that the capacity decays obviously and causes the attendant problem of safety. LiPO shows the advantage of increasing the energy density of lithium-ion batteries due to its characteristic ionic conduction when coated onto an LCO cathode. Enhancing the conductivity of cathode materials is the key factor in the success of raising their operating voltage to meet emerging market demands.

CNTs Bridged Basal-Plane-Active 2H-MoS Nanosheets for Efficient Robust Electrocatalysis.

2D 2H-phase MoS is promising for electrocatalytic applications because of its stable phase, rich edge sites, and large surface area. However, the pristine low-conductive 2H-MoS suffers from limited electron transfer and surface activity, which become worse after their highly likely aggregation/stacking and self-curling during applications. In this work, these issues are overcome by conformally attaching the intercalation-detonation-exfoliated, surface S-vacancy-rich 2H-MoS onto robust conductive carbon nanotubes (CNTs), which electrically bridge bulk electrode and local MoS catalysts.

Atomically flat semiconductor nanoplatelets for light-emitting applications.

The last decade has witnessed extensive breakthroughs and significant progress in atomically flat two-dimensional (2D) semiconductor nanoplatelets (NPLs) in terms of synthesis, growth mechanisms, optical and electronic properties and practical applications. Such NPLs have electronic structures similar to those of quantum wells in which excitons are predominantly confined along the vertical direction, while electrons are free to move in the lateral directions, resulting in unique optical properties, such as extremely narrow emission line width, short photoluminescence (PL) lifetime, high gain coefficient, and giant oscillator strength transition (GOST). These unique optical properties make NPLs favorable for high color purity light-emitting applications, in particular in light-emitting diodes (LEDs), backlights for liquid crystal displays (LCDs) and lasers.
