Abstract Pristine two-dimensional (2D) binary materials such as CB, CN, and BN possess wide electronic band gaps and weak optical responses outside the ultraviolet (UV) region, which severely limit their effectiveness in multispectral nanodevices. To address this limitation, we present a quantitative density functiona…
ABSTRACT Multivalent‐ion‐based electrochromic devices have attracted considerable attention for their excellent coloration efficiency and optical modulation. However, they remain limited by slow switching speeds and insufficient cycling stability due to the strong interactions between multivalent ions and host materia…
Abstract The capture of volatile radioiodine from nuclear fuel reprocessing off-gas streams remains a critical challenge due to the high volatility, long half-life, and biological uptake of 129I from the environment. Although silver-based sorbents provide strong iodine chemisorption, their high cost and regulatory cla…
This revised article addresses Q0196, 'How can we validate AI-based spectral interpretation so that inferred structures remain chemically auditable?' using a question-specific mathematical construction rather than a generic logarithmic template. The proposed model, termed the Auditable Spectral-Structure Posterior Mod…
Achnatherum splendens was used as a high-lignin herbaceous feedstock to compare the effects of dilute sulfuric acid and sodium hydroxide pretreatments on component degradation and cell wall structure. Chemical composition analysis, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning e…
Calotropis gigantea is widely used in traditional medicine for treating various health conditions. This study evaluated the phytochemical composition and comparative therapeutic effects of methanolic extracts from its leaves, stem bark, and roots in streptozotocin (STZ)-induced diabetic albino rats. Plant materials we…
Nannoconus , an extinct calcareous nannoplankton genus, characterized by a heavy calcite skeleton (micaliths; ~200-1400 picogram), was a major planktonic producer in the Early Cretaceous seas (~150-120 Ma) contributed to massive marine carbonate accumulations for over ~30 million years. However, the calcification site…
**FINDING:** Icosahedral symmetry group \( I_h \) (order 120) is simple, and its rotational subgroup \( A_5 \) is the smallest non-abelian simple group. The group is intimately linked to the golden ratio \(\phi\) and appears in optimal volume-to-surface ratio problems (e.g., icosahedron is the Platonic solid with maxi…
This is the instrument paper of the Structural Control series, and it is deliberately two-sided, with every claim carrying a declared evidence stratum. The telemetry side is measured: a single-channel precursor estimator — rolling median, robust MAD threshold, persistence gate — as two predeclared, cadence-scaled conf…
Magnesium (Mg) is known for its biocompatibility in degradable body implants, with mechanical properties similar to bone tissue. Pure Mg corrodes too fast for implants, but alloying or coating are methods to slow down the implant surface degradation. Using density functional theory calculations we study the adsorption…
Electromagnetic interference (EMI) shielding is essential in modern electronics, telecommunications, and aerospace systems. Graphite-based materials are promising shielding candidates due to their tunable electrical conductivity, low density, corrosion resistance, and thermal stability. However, numerical studies inve…
Abstract This work investigates the curing behavior of epoxidised soybean oil (ESO) with citric (CA), maleic (MA), and salicylic (SA) acids. The curing process was monitored by Fourier-transform infrared (FTIR) and dynamic differential scanning calorimetry (DSC) at heating rates of 5–20 °C min–1. FTIR analysis showed…
ABSTRACT Efficient anti‑/de‑icing coatings are urgently needed for outdoor infrastructures in cold climates. Here, we report a photothermal superhydrophobic coating based on ultrasmall‑bandgap tellurium nanowires (TeNWs, E g = 0.43 eV) synthesized via a surfactant‑assisted solid‑solid‑solid growth strategy. The compos…
High-temperature creep resistance is a key requirement for structural materials used in aerospace applications. However, this property remains poorly understood for the EV31 alloy. This study investigates the creep mechanisms of EV31 alloy in temperature range from 200 °C to 300 °C through experimental characterizatio…
Abstract The optical and electronic properties of a two-dimensional (2D) material are profoundly influenced by the nature of its underlying substrate, thereby making the substrate-material interactions a vital factor for both fundamental studies and technological applications. These interactions can significantly modi…
Abstract A series of dialkyl-substituted dicyanoquinodiimine derivatives (Cn-DCNQI; n = 1–7, 12) with systematically varied alkyl chain lengths has been synthesized, and the relationships among crystal structure, intermolecular electronic interactions, and organic field-effect transistor properties have been investiga…
ABSTRACT Photocatalytic oxygen reduction reaction (ORR) is a promising route for sustainable H 2 O 2 synthesis, enabling on‐demand production and in situ water remediation, yet it is still hampered by poor charge separation and migration, as well as sluggish O 2 adsorption and activation. Herein, salen‐based covalent…
This perspective proposes a structural accessibility hypothesis for interpreting negative biodegradation results in crosslinked photopolymer additive-manufacturing materials. The hypothesis is deliberately non-exclusive: an observed low biodegradation fraction may reflect intrinsic chemical recalcitrance, limited acce…
Abstract Chiral recognition is fundamentally pivotal in biomedicine, yet simultaneous discrimination of enantiomers of multiple structurally analogous molecules remains a key challenge. Herein, multicolor achiral carbon dots (CDs) (B-CDs, G-CDs, and Y-CDs) were successfully synthesized and employed for chiral recognit…
ABSTRACT Gold nanoparticles (AuNPs) exhibit size‐ and shape‐dependent physicochemical properties, yet precise morphological control under environmentally benign conditions remains challenging due to the lack of spatial regulation of nucleation and growth. Here, we explore liposome‐based nanoreactors as confined reacti…
