The Role of Interfacial Energetics and Defects on The Efficiency of Tin Perovskite Solar Cells

open access: yesSmall, EarlyView.
ABSTRACT Tin perovskites are emerging as a sustainable alternative to lead‐based photovoltaics, yet their efficiency remains limited by energy‐level mismatch and intrinsic instability from tin oxidation. Progress is further hindered by inconsistent electrical behavior, obscuring the true bottlenecks of device performance.

A Versatile Heterometallic Microporous MOF for Photocatalytic Hydrogen Generation

open access: yesSmall, EarlyView.
This work describes a green and scalable approach to robust and flexible heterometallic MOFs, MIP‐215's, with tunable photoactivity for efficient, noble‐metal‐free solar hydrogen production. ABSTRACT Photocatalytic particulate systems offer a cost‐effective solar hydrogen production but are generally limited by narrow visiblelight absorption and poor ...

Seeded‐Growth of ZIF‐8 onto Magnetic Nanoparticles: Smart Nanocarriers with Ultrahigh Drug Loading for AMF‐Triggered Release

open access: yesSmall, EarlyView.
We developed core‐shell iron oxide@ZIF‐8 magnetic‐MOF nanohybrids via a seeded growth method for magnetic hyperthermia‐triggered drug delivery. Cubic cores and thinner shells maximized heating. In‐situ doxorubicin encapsulation achieved 98% loading, better than surface encapsulation. Polymer coating improved stability.

Mg2+ Ions as Interfacial Charge Bridges for Enhanced Photocatalytic Hydrogen Evolution in Poly(Heptazine Imide)

open access: yesSmall, EarlyView.
Mg2+ confined within poly(heptazine imide) acts as a heterogenized interfacial charge bridge capable to couple synergistically the semiconductor with Pt co‐catalysts, thus enhancing hydrogen evolution. Through water polarization and hydroxide stabilization, a dynamic Mg2+‐OHδ−‐Hδ+‐Pt motif facilitates proton transfer and overcomes interfacial electron ...

Downsize Effect on Photocatalytic Syngas Production of a 2D Metal Organic Framework—Tuning the Selectivity From HER to CO2RR via Dimensional Modulation and Mechanical Exfoliation of 2D Metal‐Organic Layers

open access: yesSmall Methods, EarlyView.
A cobalt(II) 2D MOF (2D) has been downsized by covalent bond breaking to form a 1D MOF (1D) and by sonication, to form a 2D exfoliated MOF (2D‐ex). Photocatalytic CO2 reduction shows that 2D and 1D lead to H2‐enriched syngas, whereas 2D‐ex leads to CO‐enriched syngas.

Influence of Surface Roughness and Temperature on Niobium Cathodic Cage Duplex Treatment Applied to VP20TS Steel

open access: yessteel research international, EarlyView.
Niobium cathodic cage duplex treatment is applied to VP20TS steel to evaluate the influence of surface roughness and temperature on coating performance. Results show that higher temperatures promote thicker nitride layers and increased microhardness, while finer surface preparation enhances adhesion and wear resistance, revealing optimal conditions for

Chemical Recycling as a Tool for Enabling a Second Life for Polyesters

open access: yesSusMat, EarlyView.
This review presents the elucidation of the life cycle of main polyesters, detailing end‐of‐life methods, with focus of solvolysis technologies, then an analysis of LCA and TEA on literature data, an original data analytic, and, finally, a current industrial mapping of the main processes with a critical perspective on the plastic life‐cycle ecosystem ...

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Untreated Hair Dye Effluents Enter the Environment: Are They a Threat to Human Health?

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The effluents generated during the process of hair dyeing exhibit a complex composition, comprising chemical compounds with varying toxicity levels. While the adverse impact of hair dyes on human health is acknowledged, there is a notable absence of studies addressing the toxicity associated with effluents produced during these activities. The

Diving Deeper Into Mechanisms of Acrylamide‐Induced Toxicity: RNA Sequencing Reveals Transcriptomic Alteration and Retrotransposon Expression in Drosophila melanogaster

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.
