Research on the Size and Distribution of TiN Inclusions in High-Titanium Steel Cast Slabs.

High-titanium steel contains an elevated titanium content, which promotes the formation of abundant non-metallic inclusions in molten steel at high temperatures, including titanium oxides, sulfides, and nitrides. These inclusions adversely affect continuous casting operations and generate substantial internal/surface defects in cast slabs, ultimately compromising product performance and service reliability. Therefore, stringent control over the size, distribution, and population density of inclusions is imperative during the smelting of high-titanium steel to minimize their detrimental effects.

Lithium-Bond-Based Deep Eutectic Electrolyte Solutions for High-Temperature Lithium Metal Batteries.

Achieving long-term cycling stability in high-temperature lithium metal batteries (LMBs) demands both efficient ion transport and stable electrode interfaces. However, the molecular polarity and strong ionic interactions of conventional electrolytes hinder ion mobility and compromise interfacial stability. In this study, we developed a deep eutectic electrolyte based on Li-bond (Li-DEE) comprising tetraethylammonium nitrate and lithium bis(fluorosulfonyl)imide, which is different from the traditional hydrogen bonding or lithium ionic bonding electrolyte.

Impact of altered quartz surface chemistry on mechanical properties and microstructure of geopolymers.

The preparation of geopolymers from tailings rich in quartz typically requires activation to enhance final strength, though the underlying mechanism remains unclear. Quartz, as a common inert gangue mineral in tailings, was selected as the research subject. Quartz with varying reactivity was prepared through mechanical activation of different particle sizes and used for geopolymer synthesis, aiming to elucidate the strengthening mechanism of activated quartz on geopolymers.

Microstructures of Directionally Solidified NbTiFe Alloy and Its Hydrogen Permeation Properties in the Presence of HS.

Currently, the main limitations of Pd-coated Nb-TiFe dual-phase alloys include insufficient hydrogen permeability, susceptibility to hydrogen embrittlement (HE), and poor tolerance of HS poisoning. To address these issues, this study proposes a series of improvements. First, a novel NbTiFe alloy composed of a well-aligned Nb-TiFe eutectic was successfully prepared using directional solidification (DS) technology.

With the arrayed capillaries, the stable spreading of polymer solution with volume of microliter induces the formation of solution film with micrometers thickness.

Signal Modulation of Organic Photoelectrochemical Transistor by a -Scheme Photocathodic Gate: An Innovative Dual Amplification Strategy for Sensitive Aptasensing Application.

Pursuing a more efficient signal amplification strategy is highly demanded for improving the performance of the promising cathodic photoelectrochemical (PEC) sensors. In this work, we present an extremely effective dual signal amplification strategy by the integration of a -scheme nanohybrids-based photocathode with the effective signal modulation of an organic photoelectrochemical transistor (OPECT) device. Specifically, photocathodic gate material of CdTe-BiOBr nanohybrids with a -scheme electron-transfer route was designed and synthesized for preliminary improvement of the activity of the photogate; afterward, signal modulation of the OPECT system by the photocathodic gate of CdTe-BiOBr was then accomplished for further signal amplification by 2 orders of magnitude.

Phase Equilibria, Solidified Microstructure, and Hydrogen Transport Behaviour in the V-Ti-Co System.

At present, the V-Ti-Co phase diagram is not established, which seriously hinders the subsequent development of this potential hydrogen permeation alloy system.

On this basis, hydrogen-permeable VTiCo (x = 17.

Ordered and Fast Ion Transport of Quasi-solid-state Electrolyte with Regulated Coordination Strength for Lithium Metal Batteries.

Polymer based quasi-solid-state electrolyte (QSE) has attracted great attention due to its assurance for high safety of rechargeable batteries including lithium metal batteries (LMB).

Herein, we firstly demonstrate that the ordered and fast transport of lithium ion (Li ) can be realized in QSE.

Preliminary investigation of the immune activity of PmH2A-derived antimicrobial peptides from the pearl oyster Pinctada fucata martensii.

Antimicrobial peptides (AMPs) play important roles in the immune defense against pathogenic microorganisms. For instance, histone 2A (H2A)-derived AMPs is an antimicrobial peptide involved in the host's innate immune defense and immunoregulation. AMPs have been isolated from the pearl oyster Pinctada fucata martensii but their role in host defense remains poorly understood.

Dual-Modality Molecular Imaging of Tumor via Quantum Dots-Liposome-Microbubble Complexes.

Molecular imaging has demonstrated promise for evaluating the expression levels of biomarkers for the early prediction of tumor progression and metastasis. However, most of the commonly used molecular imaging modalities are relatively single and have difficulties imaging complex biological processes.

Members of the histone-derived antimicrobial peptide family from the pearl oyster Pinctada fucata martensii: Inhibition of bacterial growth.

Because it is difficult to isolate standard antimicrobial peptides (AMPs) using traditional biochemical approaches, we designed, synthesized, and evaluated a series of structurally altered histone-derived AMPs (HDAPs) from the pearl oyster Pinctada fucata martensii using molecular cloning approaches. Four histone-homolog genes (PmH2A, PmH2B, PmH3, and PmH4-1) were identified, of which PmH2A and PmH2B had yet to be described. PmH2A and PmH2B were therefore cloned using Rapid Amplification of cDNA Ends (RACE) and characterized.
