Development of an Efficient and Scalable Process for Preparing Timolol N‐Nitrosamine Impurities B, C, E, H, I, J, and Their ADMET Evaluation

Journal of Heterocyclic Chemistry, EarlyView.
N‐nitrosamine impurities (B, C, E, H, I, J) of timolol maleate are easily synthesized from diethyl malonate and 3,4‐dichloro‐1,2,5‐thiadiazole. Good yields and precise impurity profiling are made possible by the effective technique, which also ensures pharmaceutical safety and strengthens regulatory compliance.

Nephrogenic Systemic Fibrosis: A Rare Contemporary Case After a Decade of Declining Incidence

JEADV Clinical Practice, EarlyView.
ABSTRACT Nephrogenic systemic fibrosis (NSF) is a rare fibrosing disorder associated with exposure to gadolinium‐based contrast agents in patients with renal impairment. Although its incidence has markedly declined since the restriction of high‐risk linear gadolinium agents, sporadic cases may still occur.

Sustainable Metal Recovery From E‐Waste: Exploring Greener Leachates in Hydrometallurgical Processes

MetalMat, EarlyView.
Recycling of electronic waste to synthesize valuable metals using green leachate. ABSTRACT The accumulation of electronic waste (e‐waste) poses environmental hazards and leads to the loss of valuable metals such as gold, silver, copper, and rare earth elements.

Acid Sulfite Pulping of Hemp: Effects of Processing Conditions on Lyocell Pulp Quality

Journal of Polymer Science, EarlyView.
Industrial hemp is emerging as a promising renewable source for next‐generation textile fibers. This study evaluates whether acid sulfite pulping can produce hemp‐based dissolving pulp suitable for lyocell manufacturing. While the process is historically linked to increased cellulose accessibility, it did not achieve the low lignin content and ...

Approaching Gold‐Standard Sensitivity in a Portable and Versatile Gold Nanoprisms Thermoplasmonic Platform for Lateral Flow Detection of Biomolecules

Small, EarlyView.
This study presents a plasmonic thermal lateral flow (ThermoLFA) biosensor for ultrasensitive, early detection of biomolecules. By combining plasmonic gold nanoprisms (AuNPrs) and near‐infrared (NIR) laser activation, it enhances signal output beyond conventional LFAs.

Polysulfide Immobilization and Sulfur Conversion Kinetics Promotion via a Tetrathiafulvalene–Crown Ether COF@Graphene Layer for High‐Rate Lithium–Sulfur Batteries

Small, EarlyView.
A polysulfide‐regulating covalent organic framework (TUS‐44) integrating tetrathiafulvalene and crown‐ether linkers forms an electron‐delocalized, ion‐coordinative network that synergistically mediates Li–S redox chemistry. When interfaced with graphene, the TUS‐44@G layer functions as a catalytic and chemisorptive interface, enabling efficient ...

Patch Testing in Individuals With Diabetes Using Medical Devices. Part 2—Contact Allergy to Medical Device Allergens and New Patch Test Recommendations

Contact Dermatitis, EarlyView.
This study aimed to describe the prevalence of contact allergy to allergens found in diabetes medical devices (MDs) among diabetes MD users and suggest an updated MD patch test series. Of the 204 diabetes MD users (114 with skin rash to diabetes MDs and 90 without), 16.2% were positive to allergens found in diabetes MDs, which underlines the urgent ...

Gold and Nickel Release From Gold‐Plated Earrings Under Cysteine‐Modified Artificial Sweat Conditions

Contact Dermatitis, EarlyView.
Gold release from gold‐plated earrings was investigated using a cysteine‐modified artificial sweat solution designed to reflect biochemically relevant conditions. This model enabled detection of low‐level gold release. Nickel release was quantified in parallel and was detected in all samples, frequently exceeding established regulatory limits. ABSTRACT
