Soft x-ray high-harmonic generation in an anti-resonant hollow core fiber driven by a 3 μm ultrafast laser

High-harmonic upconversion driven by a mid-infrared femtosecond laser can generate coherent soft x-ray beams in a tabletop-scale setup. Here, we report on a compact ytterbium-pumped optical parametric chirped pulse amplifier (OPCPA) laser s...

The Importance of Rare-Earth Additions in Zr-Based AB2 Metal Hydride Alloys

Effects of substitutions of rare earth (RE) elements (Y, La, Ce, and Nd) to the Zr-based AB2 multi-phase metal hydride (MH) alloys on the structure, gaseous phase hydrogen storage (H-storage), and electrochemical properties were studied and...

Comparative Study of Electrochemical Biosensors Based on Highly Efficient Mesoporous ZrO2‑Ag-G-SiO2 and In2O3‑G-SiO2 for Rapid Recognition of E. coli O157:H7

Recent progress in tailoring Ni-rich layered oxides via coating and doping strategies for enhanced lithium-ion battery performance

Nickel-rich layered oxide cathodes, typified by compositions such as LiNi₁₋ₓ₋ᵧCoₓMnᵧO₂ (NCM) have garnered significant attention as high-energy-density candidates for next-generation lithium-ion batteries. However, their widespread deployme...

Influence of chemical composition and discontinuities on energy transformation and rock mass behaviour: Insights into geological dynamic

Abstract In this study, efforts were made to incorporate the influence of discontinuities and failure modes of rock into the classification of rock masses. The past tectonic activities may create microfractures in the rock body therefore th...

Investigation of the Structural, Electrical, and Optical Properties of the Nano-Scale GZO Thin Films on Glass and Flexible Polyimide Substrates

In this study, Ga2O3-doped ZnO (GZO) thin films were deposited on glass and flexible polyimide (PI) substrates at room temperature (300 K), 373 K, and 473 K by the radio frequency (RF) magnetron sputtering method. After finding the depositi...

Fast Timing Techniques in FLIM Applications

Fluorescence lifetime imaging (FLIM) is increasingly used in many scientific disciplines, including biological and medical research, materials science and chemistry. The fluorescence label is not only used to indicate its location, but also...

The electrochemical effects of pitch stabilization for supercapacitor-grade activated carbon precursors

Petroleum pitch (PP) is a by-product generated during the petroleum refining process, characterized by its high carbon content, tunable structure, and cost-effectiveness. These attributes have spurred extensive research into its potential a...

EXARIS Model Development: Enhancing Elementary Scientific and Digital Literacy

Background/purpose. Study addresses the problem of low scientific and digital literacy among Grade 6 students (Phase C) in the IPAS (Science and Social Studies) subject under the Merdeka Curriculum, particularly in the theme “Our Endangered...

Effect of Prior Rolling on Microstructures and Property of Diffusion-Bonded Mg/Al Alloy

In this study, magnesium alloy AZ91, which was cast by double roll casting system, was rolled by a rolling mill. Then, rolled magnesium alloy and magnesium alloy without being rolled were, respectively, welded with aluminum alloy 6061 by di...

Recent advances of two-dimensional materials in smart drug delivery nano-systems

Smart drug delivery nano-systems show significant changes in their physical or chemical properties in response to slight change in environmental physical and/or chemical signals, and further releasing drugs adjusted to the progression of th...

Study of the growth mechanism of a self-assembled and ordered multi-dimensional heterojunction at atomic resolution

Abstract Multi-dimensional heterojunction materials have attracted much attention due to their intriguing properties, such as high efficiency, wide band gap regulation, low dimensional limitation, versatility and scalability. To further imp...

Dynamic Assembly of Microgels and Polymers at Non‐Aqueous Liquid/Liquid Interfaces

Abstract Particle assembly at liquid–liquid interfaces presents a promising bottom‐up strategy for creating supramolecular materials with advanced functionalities. However, the significantly lower interfacial tension observed in immiscible ...

Adsorption of Nucleic Acid Bases, Ribose, and Phosphate by Some Clay Minerals

Besides having a large capacity for taking up organic molecules, clay minerals can catalyze a variety of organic reactions. Derived from rock weathering, clay minerals would have been abundant in the early Earth. As such, they might be expe...
