The effect of transition metal oxides in the La/TiO2 structure for the photocatalytic degradation of malachite green under UV and visible light irradiation

Applied Water Science
Herein, La@MxOy/TiO2 (M = V, Cr, Mn and Fe) composite catalysts were prepared based on the sol–gel method as an effective adsorbent and photocatalyst for the degradation of malachite green from an aqueous solution under UV–Vis light.

Fish Scales: A Multifunctional Biomaterial from Nature

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

Geological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

Photoactivated Signaling Networks using DNA‐Based Synthetic Organelles as Biomimetic Protocells

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Light‐triggered intercommunication between two types of organelle‐loaded liposomes lead to DNAzyme‐mediated on transcription‐guided structural reconfiguration of the organelles. ABSTRACT Membraneless organelles formed by phase‐separated nucleic acid or protein condensates play vital roles in regulating cellular functions.

Introducing Chemical Vapor Etching (CVE): A Material‐Selective Approach for Surgically Precise Tarnish Removal

Small, EarlyView.
ABSTRACT The controlled removal of corrosion products is a persistent challenge in fields ranging from industrial alloy protection to cultural heritage conservation. Achieving high precision and selectivity in subtractive treatments remains difficult because of chemical complexity and structural heterogeneity of the corrosion layers.

Fluorinated Analogs of Malachite Green: Synthesis and Toxicity [PDF]

Molecules, 2008
A series of fluorinated analogs of malachite green (MG) have been synthesizedand their toxicity to Saccharomyces cerevisiae and a human ovarian epithelial cell lineexamined. The toxicity profiles were found to be different for these two species. Twoanalogs, one with 2,4-difluoro substitution and the other with 2-fluoro substitution seem tobe the most ...

Integration of Micro‐CT and XRF Mapping for Multimodal 3D Analysis of Polychrome Wooden Artifacts

X-Ray Spectrometry, EarlyView.
ABSTRACT Over the past 5 years, computer applications have become crucial to archeological research. Since the 1990s, the focus has transitioned from data management tools to the development of virtual models. Recently, digital documentation of cultural heritage has gained considerable focus, with 3D modeling of objects.

Trade‐offs between soil biodiversity and agricultural expansion: Evidence from litter decomposition dynamics in Madagascar

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Home‐Field Advantage (HFA) theory—positing that litter decomposes faster at its site of origin—allows us to disentangle the respective influences of litter quality, soil biota composition, and microclimate on shifts in litter decomposition following land use conversion.

Selective adsorption of cationic dyes by layered double hydroxide with assist algae (Spirulina platensis) to enrich functional groups

JCIS Open
The present study involved the preparation, characterization, and evaluation of layered double hydroxide (LDH) with the assistance of the algae Spirulina platensis (NiAl-Sp and ZnAl-Sp). These materials were investigated for their potential for selective
