Despite years of effort, the precise three-dimensional structures of two crystalline polymorphs of cellulose, Iα and Iβ, are currently still unknown due to the presence of disorder in the intermolecular hydrogen bond networks, hampering the in-depth understanding of the structure–property relationship of this crystalline material. Disorder in the hydrogen bond networks of cellulose I polymorphs was investigated using terahertz spectroscopy, powder X-ray diffraction, and solid-state density functional theory in order to reveal previously undiscovered atomic-level details about the crystal structures. We show that the nature of the (dis)order in the hydrogen-bonded layers has a direct effect on the terahertz vibrational spectra, providing contrast that allows differentiating between various structures spectroscopically.

At the device level, the contradiction between performance and stability is highlighted, as well as the dynamic balance between power consumption and mechanical flexibility in wearable integration. In response to the above issues, this article delves into solutions for balancing performance stability and power flexibility.

Some studies have realized the combination of multiple rare earth ions in a single matrix through the energy transfer between different rare earth ions. As a common green/red emission center used in luminescent materials, Tb<small>³⁺</small>/Eu<small>³⁺</small> is often co-doped into different hosts. The new host has an important research value due to offering a special crystal-field-environment for the activator.

Through first principles and diffuse reflection spectroscopy, it is known that Ba<small>₂</small>In<small>₄</small>P<small>₆</small>O<small>₂₃</small> has a large optical band gap (4.26 eV), which indicates that the compound has a relatively strong optical absorption in the near-ultraviolet band.

This study proposes a novel dual inducing layer structure that simultaneously achieves energy-level alignment, enhanced charge injection, and high-quality crystalline film growth. Specifically, a BP2T inducing layer is introduced between the anode and conventional BP1T layer to enhance hole injection while maintaining high-quality epitaxial growth. The BP2T layer effectively bridges the energy-level mismatch at the anode interface and reduces lattice mismatch between BP1T and 2FPPICz, facilitating the formation of large-area, continuous crystalline films. Comprehensive characterization using atomic force microscopy (AFM), X-ray diffraction (XRD), and transmission electron microscopy (TEM) confirms the improved structural coherence and epitaxial relationships within the dual inducing layers. The hole-only device demonstrates a 136% increase in current density at 1 V, highlighting the enhanced charge injection efficiency.
