Excitonic Emission Modulation in GaSe/MoS2 Van Der Waals Heterostructure Via Plasmonic Control of Interlayer Charge Transfer

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic hybridization enables control of light emission in 2D van der Waals heterojunctions. By stacking multilayer GaSe and monolayer MoS2 on a silver film, light emission is enhanced at the edges due to plasmonic effects. In the center, where these effects are absent, charge transfer led to reduced light emission.

Miscibility and specific interactions in blends of poly[(styrene)-co-(cinnamic acid)] with poly(methyl methacrylate) and modified poly(methyl methacrylate)

open access: yeseXPRESS Polymer Letters, 2007
The miscibility behavior of poly(styrene-co-cinnamic acid) (PSCA) with poly(methyl methacrylate) (PMMA), poly[(methyl methacrylate)-co-(4-vinylpyridine)] (PMMA4VP) and poly[(methyl methacrylate)-co-(2-vinylpyridine)] (PMMA2VP) was studied.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

HPMA and HEMA copolymer bead interactions with eukaryotic cells

open access: yesMaterials Research, 2004
Two different hydrophilic acrylate beads were prepared via aqueous suspension polymerization. Beads produced of a hydroxypropyl methacrylate (HPMA) and ethyleneglycol methacrylate (EDMA) copolymer were obtained using a polyvinyl alcohol suspending medium.

Studies on the Photodegradation of Poly(Methyl Methacrylate), [PDF]

open access: yes, 1978
Abstract : Although poly(methyl methacrylate), PMMA, is known to degrade when exposed to ultraviolet radiation, studies at wavelengths other than 253.7 nm have not been done. The lack of knowledge about the mechanism of degradation of PMMA at wavelengths other than 253.7 nm hinders efforts to develop short-term test methods for predicting the long-term

Iridium Oxide Inverse Opal Anodes with Tailored Porosity for Efficient PEM Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
The synthesis of Iridium‐based Inverse Opals (Ir‐IO) is reported as electrocatalyst for Proton exchange membrane water electrolysis (PEM‐WE). Using the developed protocol it produces highly porous materials consisting either of metallic, oxidic Iridium or a combination thereof with large surface areas.

Versatile Green Transfer of Magnetoelectronics with Loss‐Free Performance and High Adhesion for Interactive Electronics

open access: yesAdvanced Functional Materials, EarlyView.
An environmentally friendly transfer printing method of nm‐thick giant magnetoresistive (GMR) sensors is demonstrated. This method, relying on water and biocompatible polyvinyl alcohol (PVA) polymer without the need of complex treatments, allows transferring thin films to a wide range of biological, organic, and inorganic substrates.

A release of potentially toxic components from the acrylic resins for soft relining dentures [PDF]

open access: yesActa Stomatologica Naissi, 2019
Introduction: Soft acrylic resins belong to a group of cold curing materials that are applied to the basal surface of the dental prosthesis in order to eliminate mechanical irritation, and to allow for the recovery of damaged or inflamed mucous membranes,
