Balancing Structural Ordering and Electrochemical Performance in LiNi0.94Co0.06O2 Cathodes via PVA-Assisted Synthesis

Ni-rich layered oxide cathodes are promising candidates for high-energy-density lithium-ion batteries; however, their electrochemical performance is strongly influenced by structural evolution, lithium stoichiometry, interfacial properties, and particle characteristics. In this s...

Psychometric evaluation of the Korean version of the Advance Care Planning Practice Scale among nurses

This study translated the Advance Care Planning Practice Scale into Korean and evaluated its psychometric properties using a sample of Korean nurses. This was a methodological study. The Advance Care Planning Practice Scale was translated using a forward–backward procedure and ex...

Millimeter-Scale, Atomically Controlled 2D Topological Insulators Revealed by Multimodal Spectroscopy

Abstract Quantum spin Hall insulators, also known as 2D topological insulators, are crucial 2D systems hosting topologically protected edge states. The working temperature of this topological quantum phase is dictated by the inverted bandgap. However, the previously identified la...

Towards predictive and sustainable indigo dyeing of denim: Linking redox chemistry, dye transport and yarn architecture

Abstract Indigo ring dyeing defines denim's characteristic appearance and fading behaviour by selectively colouring the yarn surface while preserving its white core. The key challenge is controlling radial indigo penetration to achieve the desired ring structure without unnecessa...

Influence of Shelf-Aging on Resistive Switching Characteristics of Sol–Gel-Processed ZnO and Al-Doped ZnO Structures

Sol–gel-processed zinc oxide (ZnO) is indispensable in various optoelectronic applications, such as quantum dot light-emitting diodes (QLEDs), due to its high electron transport capability and adjustable oxygen vacancy characteristics. However, its commercialization has been dela...

Enhanced UV-C Detection Performance of Perovskite Photodetectors via Controlled Surface Patterning

Ultraviolet (UV)-C photodetectors based on perovskite semiconductors are attractive because of their solution processability and excellent optoelectronic properties, but UV-induced degradation limits conventional UV-based processing. Here, controlled ultraviolet light exposure is...

Post quantum federated authentication framework for Industrial Internet of Things using FALCON threshold signatures and zero knowledge verification

Abstract Distributed authentication techniques enable edge device trust in smart manufacturing and energy infrastructure Industrial Internet of Things contexts. Existing blockchain-based authentication schemes mostly use the elliptic curve digital signature algorithm, which can b...

Poly-L-Lactic Acid Attenuates Fibrotic Remodeling During Cutaneous Wound Healing

Pathological hypoxia following cutaneous injury is a critical driver of wound chronicity and fibrotic remodeling. The nuclear receptor binding SET domain protein 2 (NSD2)/lysine demethylase 2A (KDM2A)–histone H3 lysine 36 dimethylation (H3K36me2) axis is a known regulator of hypo...

Bolus‐Only Versus Bolus‐Plus‐Infusion Tranexamic Acid for Trauma: A Propensity Score‐Matched Study

BACKGROUND: The CRASH-2 regimen for tranexamic acid (TXA) consists of a 1-g intravenous bolus followed by a 1-g infusion over 8 hours. The maintenance infusion may be challenging to administer during the early phase of trauma resuscitation. We compared mortality outcomes between...

Defect engineering and functional modulation of nickel oxide for electronic and energy devices

Nickel oxide (NiO) is a prototypical correlated transition-metal oxide in which Ni 3d–O 2p hybridization, charge-transfer interactions, and intrinsic defect chemistry govern its electronic structure and device-relevant functionality. In NiO thin films, p-type conduction, optical...

Carbon-Policy Surprises, Fossil Dependence, and Forward Downside Risk: Evidence from International Equity Markets
