Structural and Electrical Properties of Plasticized Radiation Induced Chitosan Grafted Poly(methylmethacrylate) Polymer Electrolytes

open access: yesInternational Journal of Electrochemical Science, 2014
Plasticized grafted polymer electrolytes composed of chitosan-grafted-poly(methylmethacrylate) (Ch- g-PMMA), ethylene carbonate (EC) plasticizer and lithium triflate (LiTf) salt were prepared by the solution cast technique.

The hidden science of haptics: A pedagogical review of tactile evaluation in cosmetics

open access: yesInternational Journal of Cosmetic Science, Volume 48, Issue 3, Page 600-634, June 2026.
This review explores the physiological basis of tactile perception and critically examines classical and emerging sensory methods used in cosmetics, advocating for broader methodological integration and recognition of sensory analysis in the field. Abstract Sensory analysis is a cornerstone of cosmetic development, yet remains underrepresented in peer ...

Morphology Analysis of Cu Film Fractures in Sandwiched Methylmethacrylate Plates

open access: yesMedžiagotyra, 2015
Thin films of Cu were evaporated on solid plates of polymethylmethacrylate (PMMA). A polymerization process was made to realize sandwiched structure to protect the Cu films.

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

open access: yesAdvanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Humid‐Air Condensation Heat Transfer on Hierarchical Structured Superhydrophobic Graphite Composites

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.
Humid‐air condensation on graphite composites shows that making a surface superhydrophobic is not sufficient to enhance heat transfer. A hierarchical CuO/lauric‐acid coating yields spherical droplets but promotes Wenzel‐type pinning and adds effective thermal resistance under operation.

Ionic Fragmentation of Methyl Methacrylate Induced by Synchrotron Radiation and Multiphoton Ionization

open access: yesJournal of the Brazilian Chemical Society, 1998
Ionic fragmentation of methylmethacrylate has been observed using synchrotron radiation and laser excitation. A recently developed time-of-flight mass spectrometer was used for the ionic identification.

An unexpected cause of severe and refractory PTH-independent hypercalcemia: case report and literature review

open access: yesArchives of Endocrinology and Metabolism
Hypercalcemia is a common condition in the internal medicine practice. Sometimes its cause is not readily apparent, so extensive investigation is appropriate. Here we report an unexpected cause for hypercalcemia in an elderly woman.

The Dynamic Energy Band Model of Contact‐Separation and Sliding Mode Triboelectric Charging of Polymers at the Metal‐Polymer Interface

open access: yesAdvanced Science, Volume 13, Issue 21, 13 April 2026.
Triboelectric charge generation at polymer‐metal interfaces arises from the interplay of polymer mechanochemistry, polymer physical properties, and material transfer, where ion‐derived dipoles modulate the interfacial potential and mechanochemically generated electronic states and work function differences drive electron transfer, providing a unified ...
