Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Self‐Assembled Calcite Architectures for Programmable Information Storage

Advanced Materials Technologies, EarlyView.
Programmable biomineralization enables the formation of 3D calcite architectures that encode information through spatially defined refractive‐index modulations. Data are written via laser‐directed mineralization, stored in stable voxelized mineral structures, and retrieved non‐destructively through optical diffraction, offering a pathway toward ultra ...

PROTAC‐Engineered Protein/DNA Nanoantigen is a Potent Booster for Dendritic Cell Vaccines in Cancer Immunotherapy

Advanced Science, EarlyView.
A PROTAC‐functionalized protein/DNA‐integrated nanoantigen platform is developed to enhance dendritic cell vaccine potency. By combining a VHL‐recruiting peptide‐modified antigen with a sustained expression plasmid within CaCO3 nanoparticles, this system amplifies cross‐presentation, promotes DC maturation, and elicits robust Th1 and CTL responses ...

Optimizing feather hydrolysate via machine learning for microbial recycling of waste concrete fines

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The concrete industry faces significant challenges from CO2 emissions and the disposal of waste concrete fines (WCF). Microbially induced calcite precipitation (MICP) can bind WCF into bioconcrete, but the high cost of commercial culture media hinders its application.

Remineralisation of Reverse Osmosis (RO) Water Using Synthetic Aragonite

Water and Environment Journal, EarlyView.
ABSTRACT Reverse osmosis (RO) treated water often requires remineralisation to restore Ca2+ ions, hardness and alkalinity, particularly for potable water. This study compares the dissolution characteristics of two forms of calcium carbonate, aragonite and calcite.

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

Journal of Raman Spectroscopy, Volume 57, Issue 8, Page 1463-1480, August 2026.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman

Adsorption of Tetracycline and Congo Red by a Nitrogen and Sulfur Co‐Doped Crab Shell‐Derived Biochar (BC‐N/S): Mechanism and Estimated Cost

ChemistrySelect, Volume 11, Issue 30, 10 August 2026.
A nitrogen–sulfur co‐doped crab shell‐derived biochar (BC‐N/S) was prepared through a facile one‐pot synthesis. BC‐N/S showed improved surface area (13.462 m2g−1) and enhanced pore width. The BC‐N/S adsorbent displayed 100% preferential adsorption efficiency for Congo red compared to tetracycline (96.47%) in binary solution.

A New Method for Exploring the Early Stages of the Crystallization of Small Organic Carboxylic Acids at Constant pH and Temperature and Quantitatively Assessing Additive Effects

Chemistry–Methods, Volume 6, Issue 7, July 2026.
We introduce a titration‐based method to explore the early stages of the crystallization of small organic molecules with carboxylic acid functions in water. It enables the determination of fundamental physicochemical characteristics (pKa values and solubilities) and the quantitative study of prenucleation, nucleation, and early postnucleation stages ...

Enhancing the Properties of PA6 and PA6/Ionomer Scraps Blend With CaCO3 Nanoparticles: Rheological, Mechanical, Thermal, and Morphological Evaluation

Polymer Engineering &Science, Volume 66, Issue 6, Page 4247-4260, June 2026.
ABSTRACT This study investigated the effects of incorporating ionomer scraps and CaCO3 nanoparticles on the rheological, mechanical, thermal, and morphological properties of neat polyamide 6 (PA6) and a PA6/ionomer scraps (80/20) blend. The ionomer formed an immiscible dispersed phase within the PA6, acting as an impact modifier; however, it reduced ...
