Wafer-scale epitaxy growth of high-mobility p-type boron carbon nitride
|
Abstract A long-standing bottleneck in realizing two-dimensional (2D) CMOS technology lies in the lack of high-performance p-type semiconductors1,2,3,4. Strong electron-doping tendencies, orbital localization and pronounced hole scattering have collectively impeded the development of stable, efficient p-type 2D materials. Here we report the epitaxy growth of boron carbon nitride (BCN) as a high-performance p-type semiconductor.

Methods: A 2 × 2 two-factor structural design was incorporated into this research to carry out a randomized controlled trial. 35 participants underwent random allocation to the intervention arm (n = 17) and the control arm (n = 18).
Precision-engineered STING agonist nanoparticles enable coordinated mucosal-systemic immunity for durable pan-β-coronavirus protection
|
Abstract A major barrier in mucosal vaccine development is achieving localized immunity without systemic toxicity. Here we engineered NanoCF501, a nanoparticulate STING agonist formulated with a 2-ethyl-2-oxazoline polymer. As an adjuvant, NanoCF501 facilitates efficient mucus penetration and localized respiratory retention, minimizing systemic exposure as confirmed by pharmacokinetics in rats.

Giant trion modulation in scalable monolayer MoS 2 via plasmonic HfN gates
Abstract Monolayer two-dimensional transition-metal dichalcogenides offer strong excitonic responses and gate-tunable optical properties, making them attractive for next-generation photonic and optoelectronic devices. However, achieving wafer-scale, room-temperature operation with a high photoluminescence modulation depth remains a key challenge owing to the limited electrostatic control and inefficient light–matter coupling.

Time-cost combined optimization in planning infrastructure construction projects under environment induced time‐window constraints
1 INTRODUCTION The classical time–cost trade-off (TCT) concept has been extensively studied in construction project management (Ahuja et al., 1994), building upon the critical path method (CPM) framework (Kelley, 1961; Kelley & Walker, 1959).
Unravel the rotational and translational behavior of a single squirmer in flexible polymer solutions at different Reynolds numbers - Communications Physics
Abstract Microorganisms such as bacteria and algae navigate complex fluids, where their dynamics are vital for medical and industrial applications. However, the influence of the Reynolds number (Re) on the transport and rotational behavior of microswimmers in viscoelastic media remains poorly understood. Here, we investigate these effects for a model squirmer in flexible polymer solutions across a range of Re using Lattice Boltzmann simulations.
Integrating posture‐hour constraints into construction scheduling to enhance workforce wellbeing
1 INTRODUCTION Occupational health and safety (OHS) remains a critical challenge in construction, where musculoskeletal disorders (MSDs) account for over 20% of work-related injuries globally (Holmström et al., 1995). These disorders—ranging from acute strains to chronic joint degeneration—primarily stem from prolonged exposure to non-neutral postures like bending, squatting, or overhead work (Potvin et al., 1991).

How Do Glycine‐Induced Bent Structures Influence Hierarchical Nanostructuring and Suprastructural Handedness in Short Peptide Assembly?
Materials and Sample Preparation All the peptides used were obtained from China Peptides Co., Ltd. (www.chinapeptides.com), with a purity of >98%. Note that in order to avoid the electrostatic effect of the terminal carboxylate and amine groups, these peptides were capped through amidation at their C-termini and acetylation at their N-termini during synthesis.
On the Tension Between the Elemental Nature and the Ethical Other in Levinas’s Thought: An Interpretation Conducted with the Body as a Clue
1. Introduction: Levinas and Natural Philosophy The origins of Western philosophy can be traced back to the natural philosophy of ancient Greece, where the initial core issue was the question of the origin of the world. In the development and evolution of natural philosophy, Western philosophy’s interpretations of nature have roughly formed the following three frameworks: cosmology, teleology, and mechanism.

Chiral inversion induced by aromatic interactions in short peptide assembly - Nature Communications
Abstract Although hydrophobic interactions provide the main driving force for initial peptide aggregation, their role in regulating suprastructure handedness of higher-order architectures remains largely unknown. We here interrogate the effects of hydrophobic amino acids on handedness at various assembly stages of peptide amphiphiles.

Inherited Construction of Porous Zinc Hydroxide Sulfate Layer for Stable Dendrite-Free Zn Anodes A stable Zn anode for mitigating dendritic growth, corrosion and byproducts is vital for exhibiting high-performance electrochemical properties in aqueous Zn-ion batteries. An artificial solid/electrolyte interphase is an effective protective strategy for Zn anodes. Herein, a uniform layer of zinc hydroxide sulfate (ZHS) derived in situ from a ZIF-8 membrane was developed on a Zn anode.

The temperature-controlled optimization of g-C3N4 structure significantly enhances the efficiency of photothermal catalytic NO removal
The temperature-controlled optimization of g-C3N4 structure significantly enhances the efficiency of photothermal catalytic NO removal The efficiency of photocatalytic NO removal is often constrained by catalyst lifespan and secondary contamination from reaction products. Therefore, in this study, g-C3N4 (CN) was incorporated into a photothermal reaction system for synergistic NO removal via photothermal effects.

Research Progress in Gas Separation and Purification Based on Zeolitic Materials
4. Separation Mechanisms The gas separation with zeolites/zeolitic membranes is generally divided into two processes: surface adsorption and pore diffusion. Firstly, gas molecules are adsorbed on the surface of zeolites/zeolitic membranes; then, under the action of chemical potential, adsorbed molecules transition from one adsorption site to the next adsorption site or vacancy, thereby entering the zeolite channel and diffusing to the permeation side.
Effect of Achiral Glycine Residue on the Handedness of Surfactant-Like Short Peptide Self-Assembly Nanofibers
Surfactant-like short peptides are a kind of ideal model for the study of chiral self-assembly. At present, there are few studies on the chiral self-assembly of multicharged surfactant-like peptides. In this study, we adopted a series of short peptides of Ac-I4KGK-NH2 with different combinations of L-lysine and D-lysine residues as the model molecules.

Integrated MOF-74 Coatings on Magnesium for Corrosion Control, Cytocompatibility, and Antibacterial Properties
Biodegradable Mg and its alloys can degrade safely in vivo without toxicity. The major bottleneck inhibiting their clinical use is the high corrosion rate, which leads to the loss of mechanical integrity prematurely and bad biocompatibility. One ideal strategy is the modification with anticorrosive and bioactive coatings. Numerous metal–organic framework (MOF) membranes show satisfactory anticorrosion performance and biocompatibility.
