Nanoparticles in Periodontology and Implant Dentistry: From Mechanisms to Clinical Applications

Journal of Periodontal Research, EarlyView.
Nanotechnology holds significant promise in improving dental care, yet there is a need for more reliable clinical studies to validate its effectiveness and safety. ABSTRACT Recent advances in nanotechnology are reshaping the landscape of periodontology and implant dentistry, particularly through the application of nanoparticles (NPs).

Photodegradation of commercial insect repellents containing DEET and IR‐3535 under ultraviolet light associated or not with chemical ultraviolet filters evaluated by Raman spectroscopy

Photochemistry and Photobiology, EarlyView.
This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

Glove Reuse Limits in Hair Dyeing: Permeation of p‐Phenylenediamine and Aminophenols Through Natural Rubber Latex and Neoprene After Repeated Washing

Contact Dermatitis, Volume 95, Issue 3, Page 309-317, September 2026.
Disposable glove reuse reduced chemical protection during repeated hair‐dye exposure. Under ASTM F739 testing, natural‐rubber‐latex deteriorated rapidly after one reuse, whereas neoprene performed better initially but also declined over repeated cycles. Wash type had no significant effect. These findings support single‐use only and discourage the reuse

Auto‐Click Synthesis of a Copper(I)–N‐Heterocyclic Carbene Porous Organic Polymer and Its Transmetalation to Palladium(II) for Azide–Alkyne Cycloaddition and Cross‐Coupling Reactions

European Journal of Inorganic Chemistry, Volume 29, Issue 23, 13 August 2026.
An azide‐functionalized Cu(I)–NHC complex acts as both a monomer and a catalyst in an auto‐click polymerization, yielding a Cu(I)–NHC polymer that can be transmetalated to Pd(II). The two materials catalyze copper‐catalyzed azide–alkyne cycloaddition, C–N/C–O coupling, and Suzuki–Miyaura reactions, while copper reloading restores activity.

Ozone pretreatment of wastewater containing aromatics reduces antibiotic resistance genes in bioreactors: The example of p-aminophenol

Environment International, 2020
Aromatic matters are widely present in wastewater, especially industrial wastewater, and may lead to a high abundance of antibiotic resistance genes (ARGs) in wastewater treatment bioreactors and stimulate horizontal transfers of ARGs.

Process Design and Economics of Production of p-Aminophenol

, 2021
Para-Aminophenol is one of the key chemicals required for the synthesis of Paracetamol, an analgesic and antipyretic drug. Data shows a large fraction of India's demand for Para-Aminophenol being met through imports from China. The uncertainty in the India-China relations would affect the supply and price of this "Key Starting Material." This report is

Increasing the reporting of adverse drug reaction‐related hospitalizations using an ICD‐10‐based identification workflow: A multicentre study from Switzerland

British Journal of Clinical Pharmacology, Volume 92, Issue 8, Page 2937-2948, August 2026.
Background Reporting adverse drug reactions (ADRs) is essential for drug safety. In Switzerland, healthcare professionals are legally required to report serious and unlabelled ADRs, yet under‐reporting remains widespread. We tested a novel method to increase reporting of ADR‐related hospitalizations.
