Diacetylene‐Functionalized Glycan Mimetics for Receptor‐Mediated Cluster Imprinting in Model Membranes

open access: yesMacromolecular Rapid Communications, EarlyView.
Diacetylene‐containing glycan mimetics cluster upon selective lectin binding in GUVs. Subsequent irradiation leads to the formation of fluorescent polymer clusters, while non‐clustered glycan mimetics remain unaffected in the membrane. ABSTRACT The glycocalyx, a dense layer of glycoproteins and glycolipids on eukaryotic cells, is essential for cellular

Hierarchically Porous Coatings for Cellulose Fibers by Core–Shell Particle Templating

open access: yesMacromolecular Rapid Communications, EarlyView.
Hybrid and functional core–shell particles comprising a silica core and a polymer shell were synthesized and used to develop a coating and etching process applied to a cellulose substrate. This resulted in highly porous, functional coatings on a cellulose membrane for further application in cellulose‐based adsorbers and advanced membrane technology ...

GC-MS Determination of Flunitrazepam and its Major Metabolite in Whole Blood and Plasma [PDF]

open access: yes, 2017
A gas chromatography-mass spectrometry method was developed for the analysis of flunitrazepam (FN) and its major metabolite, 7-amino-flunitrazepam (7-amino-FN), in both plasma and whole blood.

Diffusion Coefficients of Organic Compounds in Molten High‐Impact Polystyrene

open access: yesPolymer Engineering &Science, EarlyView.
Schematic overview of the determination of diffusion coefficients in molten high‐impact polystyrene. ABSTRACT Polystyrene (PS) is a widely used packaging material, but its recycling for food‐contact applications is still limited, partly due to a lack of quantitative data on the migration behavior of potential contaminants.

Environmental endocrine disrupting chemicals in urine and follicular fluid: Association with steroid hormones and risk of polycystic ovarian syndrome

open access: yesEnvironmental Chemistry and Ecotoxicology
Organophosphate esters (OPEs), bisphenols, benzophenones, and parabens are acknowledged as endocrine disrupting chemicals (EDCs) and used as flame retardants, plasticizers, and personal care products, but their associations with steroid hormone levels in

Photochromic carbazole photoinitiators for precision visible‐light photopolymerization

open access: yesPolymer International, EarlyView.
New carbazole–naphthopyran derivatives were employed as visible‐light‐activated photoinitiators, enabling rapid and localized radical photopolymerization to produce well‐defined thin solid objects within minutes. Abstract Two carbazole derivatives, each incorporating a naphthopyran unit and an aromatic ketone, were synthesized and evaluated as ...

A novel sulfur‐containing photoinitiator based on benzophenone derivatives for rapid photopolymerization

open access: yesSmart Molecules, EarlyView.
This study develops a series of unimolecular photoinitiators, BP‐S1‐5, by incorporating hydrogen‐donating groups into a benzophenone framework. This method reduces the reliance on co‐initiators, and enables BP‐S1‐5 with efficient photoinitiation and excellent molding capability.

Visible‐light‐promoted catalyst‐free benzylic C‐H oxidation using molecular oxygen as a green oxidant

open access: yesSmart Molecules, EarlyView.
A green and simple photo‐oxygenation of benzylic C‐H bond with molecular oxygen was developed for the preparation of a series of carbonyl compounds. The straightforward C‐H carbonylation strategy features catalyst‐ and additive‐free reaction conditions, only oxygen as a green oxidant, broad scope and scalable, and the simple‐operation nature.
