This paper proposes a novel theoretical framework, termed Atomic Structure Self-Repair (ASSR), centered around the inherent capacity of atomic structures to autonomously recover from perturbations. The core concept posits that atoms possess internal, adaptive algorithms that, upon encountering disturbances, actively r…
Abstract Herein, a highly rigid monomer, 2-(2-hydroxyethyl)-1,3-dioxoisoindoline-5-carboxylic acid (HTI), was readily prepared from biosourced malic acid. A series of PET copolyesters were fabricated through an in situ chemical upcycling strategy, in which HTI units were inserted into the backbones of the PET waste vi…
Abstract Non-canonical amino acids (ncAAs) are privileged building blocks for the synthesis of natural products, biocatalysts, and drug molecules. Among them, γ-tertiary-nitro-α-amino acids are highly valuable yet remain scarcely explored due to challenges in synthetic accessibility. Although pyridoxal-5′-phosphate (P…
ABSTRACT 2D Ruddlesden‐Popper perovskites exhibit strong excitonic behavior, but their performance is simultaneously governed by exciton‐phonon coupling and lattice dynamics. Here, we investigate the halide‐dependent lattice dynamics and its influence on exciton behavior in butylammonium‐based low‐dimensional perovski…
Este póster científico presenta un estudio de ingeniería de calidad enfocado en el empaque primario (blister) utilizado para los catéteres Sure Pro. El trabajo surge porque el molde original (Revisión A), tras uso prolongado, comenzó a mostrar variabilidad dimensional, y al no existir especificaciones internas en el p…
M and below) represents additional challenges. In this paper, we first describe a fast and reliable method to measure aqueous solubility of drug-like molecules in a 96-well plate format using only conventional laboratory equipment and a UV absorbance plate reader. The method was validated against the gold-standard sat…
ABSTRACT The conventional hybrid strategy that directly links long‐range charge‐transfer (LRCT) and short‐range charge‐transfer (SRCT) units through a single bond inevitably induces an uncontrollable electron push–pull effect, resulting in emission redshift and spectral broadening. In this study, we propose a spiro‐me…
The photocatalytic degradation of Ciprofloxacin (CIP) was evaluated under ultraviolet photo irradiation and a composite of β-Ga2O3 with nanocellulose citrate-capped fibers (CNCFs) at an 80:20 weight ratio (β-Ga2O3/20%CNCFs). At a dosage of 2 mg photocatalyst and optimized conditions, the CIP degradation rate (k = 2.88…
Scientific workflows on large computing clusters increasingly combine massively parallel simulation engines, machine-learned models, and theory development with the technical aspects of installation, testing and debugging, batch scheduling, and designing architecture-specific GPU-accelerated software. On leadership-cl…
Electron motion in crystalline solids is conventionally described in terms of Bloch states that occupy well‑defined energy bands. In many quantum materials, however, the actual trajectories followed by electrons can be highly non‑trivial, involving coherent superpositions, topological constraints, and interactions wit…
Background: CT is limited for local staging of bladder cancer due to insufficient soft-tissue contrast. Photon-counting detector (PCD) CT with low-keV virtual monoenergetic images (VMIs) provides greater lesion contrast with acceptable image noise and high resolution and may aid assessment for muscle invasion.
ABSTRACT Photocatalytic hydrogen production from water, particularly seawater, offers a promising route for converting solar energy into storable chemical fuels. However, despite considerable efforts in photocatalyst design, the influence of seawater ions on photocatalytic processes remains poorly understood. In this…
Abstract Electrocatalytic oxidation of biomass-derived platform molecules represents a pivotal strategy for chemical production and reducing reliance on fossil resources. Among various biomass-derived platforms, 5-(hydroxymethyl)furfural (HMF) stands out as one of the most promising candidates. Its oxidation products…
Adaptive biological systems regulate molecular recognition through enzymatic transformations that convert inactive precursors into functional states. Emulating such enzyme mediated gain-of-function behavior in synthetic supramolecular systems remains challenging because productive activation often competes with undesi…
Complete scission of the C≡O triple bond in carbon monoxide by an actinide complex has so far been restricted to multimetallic nitride-bridged systems, where the reaction proceeds via formation of strong C─N multiple bonds. Here we report an alternative mode of complete CO cleavage mediated by a mononuclear uranium(IV…
Analytical devices based on pyrolyzed biomass have gained increasing attention in analytical chemistry due to their low cost, high electrical conductivity, intrinsic filtration capability, and high sensitivity. However, they still exhibit significant variations in electrochemical responses, both faradaic and capacitiv…
Coarse-graining a Markov chain by merging microstates (lumping) almost always destroys Markovianity: the reduced dynamics acquires memory, and exact reduced descriptions require semi-Markov constructions. We introduce and solve a class of reversible finite Markov chains for which the opposite extreme holds. The class…
The concept of quantum geometric pressure (QGP) is introduced as a novel form of internal force that arises purely from the geometric deformation of electronic band structures. In a many‑electron system, changes in the lattice geometry or external strain modify the quantum metric and Berry curvature tensors, thereby g…
This paper develops a revised mathematical solution framework for the chemistry challenge "How can life-cycle chemistry be integrated into polymer design before a material is manufactured?". The proposed Ex-Ante Lifecycle Polymer Design Objective (ELPDO) was constructed after an earlier formulation failed or remained…
