Superficial chemical peels and microdermabrasion are used for many dermatologic conditions. A common condition treated with these modalities is acne vulgaris. In this review, we discuss the theory behind the technique of these procedures and describe the application and complications of each of these procedures in the office setting. The evaluation of patients before proceeding with the procedure and discuss pre- and postpeel regimens used for patients is discussed. We also analyze studies on both of these in-office procedures and comparative studies between the 2 most commonly used superficial chemical peeling agents, glycolic and salicylic acid.

The durability and flame retardancy of cotton fabrics have been the focus of long-term research. In this paper, a method for preparing flame retardants through the direct modification of biomass was proposed, and the durable flame retardant of homologous cottonseed meal modified biomass flame retardants for cotton fabrics was achieved through biomass composition analysis and modeling. In this study, a cottonseed meal-phosphoric acid-boric acid synergistic bio-based flame retardant (CPB) was synthesized and characterized.

The development of new photochromic systems is motivated by the possibility of controlling the properties and functions of materials with high spatial and temporal resolution in a reversible manner. While there are several classes of photoswitches operating in solution, the design of systems efficiently operating in the solid state remains highly challenging, mainly due to limitations related to confinement effects. Triaryl-hydrazones represent a relatively new subclass of bistable hydrazone photoswitches exhibiting efficient / photochromism in solution.

species constitute the most common cause of fungal infections in humans; the emergence of resistance and biofilm formation by species further threaten the limited availability of antifungal agents. Over the past decade, . has caused significant outbreaks worldwide and has emerged as a human pathogenic fungus that causes diseases ranging from superficial to life-threatening disseminated infections.

The aim of the present work is to study the atmospheric corrosion behavior of metals exposed to both urban (Milan, IT-Lombardia) and marine (Bonassola, IT-Liguria) atmospheres in Italy. A number of coupons (100 × 150 mm) of carbon steel (CS), hot-dip galvanized steel (GS) and different grades of stainless steel (SS) were exposed. At fixed periods of time, samples were characterized by means of Linear Polarization Resistance (LPR), mass loss tests and corrosion product analysis.

Environmental endocrine disruptors constitute a category of exogenous compounds that interfere with the endocrine system's functions in organisms or cells. As a class of particularly representative endocrine-disrupting chemicals, the accumulation of per- and polyfluoroalkyl substances potentially leads to adverse health effects, including hormonal disruptions, developmental issues, and cancer. However, the classification of these disruptors is intricate, and the data on their potential health risks is scattered.
