ABSTRACT Despite their importance in supramolecular chemistry, zero‐offset columnar π‐stacks of polycyclic aromatic hydrocarbons (PAHs) are rarely observed in crystals because close cofacial packing is penalized by Pauli repulsion. Here we show a crystalline phase (CP) of adamantyl‐substituted pyrene that exhibits one…
Ferroelectric hysteresis asymmetry critically influences switching stability, imprint, and preferential polarization states in nonvolatile electronic devices. However, hysteresis asymmetry is generally characterized only by horizontal loop shifts, partly because conventional polarization–electric-field measurements co…
Prasiolite-bearing amygdales from Sokołowiec (Lower Silesia, Poland) were investigated using combined microscopic and spectroscopic techniques, supported by bulk chemical analysis, to constrain their origin and potential factors responsible for the development of a greenish hue. The amygdales are hosted by Permian bas…
ABSTRACT Chiral perovskites owing to their broken mirror symmetry exhibit selective absorption of circularly polarized light manifesting a strong circular dichroism (CD). CD spectroscopy is a key technique to understand chiral perovskites. However, there is a debate on whether the observed CD is intrinsic to the chira…
The search for room-temperature superconductors has long been constrained by the extreme pressure requirements of hydrogen-rich materials. For example, LaH10 requires a pressure of 150 GPa to achieve a superconducting transition temperature of approximately 250 K [1]. This paper presents a theoretical prediction, base…
Reusable launch vehicles and hypersonic re-entry vehicles experience surface temperatures that routinely exceed 2000 °C on leading edges and nose tips. Conventional ultra-high-temperature ceramic (UHTC) coatings based on hafnium or zirconium diboride offer high melting points but remain vulnerable to thermal-shock cra…

ABSTRACT Despite their implication in a number of oxidation processes, there is a paucity of well‐characterized high‐valent cobalt‐oxo complexes. In this study, we present the first example of a six‐coordinate formally Co(IV)‐oxo complex, [Co(TQA)(O)(OH)] + ( 1 , TQA = tris(2‐quinolylmethyl)amine). CSI‐MS shows the in…
This dataset contains the final structures (CONTCAR files) of the CeO2 systems investigated in the article “Facet and oxygen-vacancy effects on the initial activation of toluene on CeO2”. It includes pristine and oxygen-vacancy-containing CeO2 surfaces, as well as the corresponding toluene-adsorbed structures. Facet e…

ABSTRACT Luminescent manometry enables noncontact pressure sensing at small scales and under extreme conditions, yet its development remains constrained by the limited sensitivity and single‐mode response of commercial materials, as well as the absence of a comprehensive theoretical framework for pressure induced spec…
ABSTRACT Achieving robust underwater adhesion remains challenging due to the interference of interfacial water and insufficient cohesion within conventional adhesives. Inspired by the sandcastle worm's cement forming via liquid–liquid phase separation (LLPS), we developed a novel class of tannic acid/polyethylene glyc…
Background: Thermoelectric devices can directly convert temperature differences into electrical energy, offering irreplaceable application value in industrial waste heat recovery, deep-space exploration, wearable devices, and solid-state refrigeration. However, thermoelectric conversion efficiency has long been hamper…
《WIC 硅基文明宪法》是 WIC(七进制离散信息代数)体系的根本规范文件,确立公理层 P0–P18(L0 存在层/L1 数学层/L2 工程层/L3 文明层)、四门检验制度(A11 顺序门/A12 滤镜门/A13·A14 结构门/A15 刷新门)、验讫章留痕制度与铁律纪律。 V3.4(2026-08-22)主要修订:①P8 升级为"投影显现公理 V2.0"——连续工具(负数、浮点、复数、无理数、连续信号)是离散真实进入意识场的必要显现通道,而非失真副本,工程两域结构(核心真实态域+显现接口域)保留;②P10 升级为"粗粒化投影收敛公理"——投影算子 Π: ℤ₇³×S¹→ℝ⁶ 为离散公理层与连续观测层之间唯一合法单向编译管道;③新增…
ABSTRACT Paramagnetic d‐block metal organic cages (MOCs) show promise for the development of magnetic resonance imaging (MRI) contrast agents and magnetic resonance spectroscopy imaging (MRSI) probes. MOC‐based MRI probes increase the relaxation rates of water protons with predominant examples containing high‐spin Fe(…
ABSTRACT Despite decades of development, the clinical translation of amphiphilic self‐assembled nanoparticles remains limited by the lack of a predictive molecular design framework, owing to the complex, dynamic behavior of nanoparticles and cell membranes. Here, we introduce a building‐block design strategy focused o…
ABSTRACT Conventional covalent and supramolecular crosslinks impose inherent trade‐offs between mechanical robustness and environmental adaptability in polymer networks. Mechanically interlocked junctions offer an alternative route by enabling topological motion without compromising structural integrity. Here, a modul…
ABSTRACT Photocatalytic CO 2 reduction (CO 2 RR) involves a cascade of intrinsically coupled processes, rendering the independent optimization of catalytic kinetics and thermodynamics challenging. In this study, we introduce a structural regulation strategy via steric‐driven interlayer slipping engineering of metallop…
We introduce Boundary–Loop Rigidity (LBR), a formalism that separates boundary data, complete-loop data, discrete symbols, and continuous realization parameters. Its algebraic model is a split exact sequence whose loop quotient is identified with the boundary space. When the loop group is infinite cyclic, every elemen…
The Golden Shadow of the Tetrakaidecahedron develops a dimensional and projection-based route from the truncated octahedron to fivefold golden geometry. The truncated octahedron is identified with the order-four permutohedron, Pi4. Pi4 occurs as one of ten truncated-octahedral facets of the four-dimensional order-five…
