The currently used patch test concentration for formaldehyde is 1.0% (wt/vol) in water. However, clinical experience and previous studies suggest that 1.0% might be insufficient for detecting an optimized number of clinically relevant cases of contact allergy to formaldehyde. To
A green, one-step method for synthesis of graphene-Au nanoparticles (graphene-AuNPs) was introduced in this article, using an environmentally benign hexamethylenetetramine (HMTA) as reducing and stabilizing agent. HMTA slowly was hydrolyzed to generate aldehyde ammonia to reduce graphene oxides (GO) and

Relatively little is known about the epidemiology of allergic contact dermatitis in older individuals. We sought to determine the frequency of positive and clinically relevant patch test reactions in older individuals (≥ 65 years old) referred for patch testing, and

Ultraviolet (UV) photodetectors based on ZnO nanostructure/graphene (Gr) hybrid-channel field-effect transistors (FETs) are investigated under illumination at various incident photon intensities and wavelengths. The time-dependent behaviors of hybrid-channel FETs reveal a high sensitivity and selectivity toward the near-UV region at
Ternary metal oxides have been receiving wide attention in electrochemical energy storage due to their rich redox reactions and tuneable conductivity. We present a simple solution-based method to prepare a 3D interconnected porous network of ternary metal oxide (CoMoO₄ and
