Structure–Property Relationships in Bioactive Poly (Vinyl Alcohol) Films Incorporating Natural Phenolic Additives for Sustainable Active Packaging

This study aimed to investigate bioactive poly (vinyl alcohol) (PVA) films incorporating three chemically distinct naturally phenolic additives—aronia extract (A), apple peel extract (AP), and rutin (R)—as individual functional modifiers for active packaging applications. Here, w...

Turning Nd‐Fe‐B Swarf Into High‐Value Bulk Feedstocks via Sustainable Hydrogen Plasma: From Rare‐Earth Oxides to Metals and Hydrides

ABSTRACT Rare‐earth permanent magnets (REPMs) are crucial for electric vehicles, wind turbines, and other high‐efficiency electric motor systems. However, their production is energy‐intensive, and global recycling rates are below 0.2%. Machining swarf is the main industrial waste...

How fluorinated cyclic ether shapes localized high concentration electrolytes

Localized high concentration electrolytes (LHCEs) have emerged as a transformative choice, simultaneously exhibiting good electrochemical stability, sufficiently fast ionic transport, and improved rate capability. The design principle is to dilute the conventional electrolyte wit...

Suppressing Deep Ion Trapping in TiO2 Electrochromics via Interfacial Engineering of WO3–Al2O3/VOx Heterostructures

Single-component metal oxide electrochromic films suffer poor charge utilization and deep-site ion trapping, giving non-uniform charge injection. Targeting heterostructure engineering rather than new material discovery, bare TiO2, TiO2/WO3, TiO2/WO3-Al2O3 and TiO2/WO3-Al2O3/VOx f...

Small Activating RNAs: A Curated Database and an Overview of Rational Design Principles

RNA activation (RNAa), mediated by small activating RNAs (saRNAs), upregulates endogenous gene expression through recruitment of the Argonaute proteins to the promoter, natural antisense transcripts, or other noncoding RNAs. This mechanistically distinct modality addresses an unm...

Hierarchical Bayesian calibration of mesoscopic models for ultrasound contrast agents from force spectroscopy data

Ultrasound-guided drug and gene delivery (USDG) is a promising non-invasive approach for targeted therapeutic applications. Mechanical properties of encapsulated microbubbles (EMBs), which serve as contrast agents, affect their interactions with ultrasound and are, thus, critical...

Techno-economic assessment of the transportation alternatives and safety issues

This document presents the key activities required to develop and propose optimal low-to-zero-emission transport solutions tailored for small and medium-sized mining operations. It provides a structured framework for identifying, assessing, and recommending sustainable transporta...

The role of the support in catalyzing the gas-phase H2 production onto Pd-C3N4/TiO2 assisted by light

H 2 production through gas-phase photocatalysis remains limited by the poor light-harvesting ability and insufficient thermal activity of many conventional photocatalysts. In this work, Pd-loaded TiO 2 /C 3 N 4 composites were prepared to investigate the complementary role of bot...

Silver‐Modulated Copper Dynamics Under Pulsed Tandem Electrochemical CO 2 Reduction

ABSTRACT Pulsed electrolysis and Cu‐Ag tandem catalysis are both promising strategies for electrochemical CO 2 reduction, yet their interplay remains unclear. Here, we show that pulsed operation does not preserve the as‐prepared Cu‐Ag catalyst and instead generates a dynamic bime...

Use of Hydrogen Energy Storage to Stabilize Solar Power Output With an Energy Efficiency Analysis for European Union Member Countries

ABSTRACT Seasonal energy storage as compressed hydrogen offers a potential solution to balance the power grid as intermittent renewable energy sources are expected to increase in capacity due to decarbonization efforts in developed countries. Public hourly electricity production...

Local androgen and 11-oxyandrogen metabolism and signaling emerges as a novel prognostic and therapeutic axis in high-grade serous ovarian cancer

Abstract Background High-grade serous ovarian cancer (HGSOC) is the most lethal gynaecological malignancy, exhibiting marked heterogeneity that complicates treatment. The implications of intratumoral androgen metabolism and signalling, particularly involving 11-oxygenated androge...

Comparison of Two Nectar Field Sampling Methods on Three Plant Species from the Family Ranunculaceae

Research on floral nectar quantity and composition is increasingly frequent, yet existing studies predominantly focus on plant species with larger flowers that yield abundant nectar. Consequently, standard collection techniques like the microcapillary method are often optimized o...
