Enzyme‐Regulated Extended Swelling of Hydrogels for Dehiscence‐Less Tissue Expansions

open access: yesAdvanced Functional Materials, EarlyView.
An interpenetrating hydrogel network with swelling under regulation by enzymatic degradation (INSURED) is fabricated to avoid dehiscence. INSURED remains structurally intact post‐implantation, while HYAL injection enables control over the onset and rate of swelling.

Origins and Spatial Distribution of Non-Pure Sulfate Particles (NSPs) in the Stratosphere Detected by the Balloon-Borne Light Optical Aerosols Counter (LOAC)

open access: yesAtmosphere, 2020
While water and sulfuric acid droplets are the main component of stratospheric aerosols, measurements performed for about 30 years have shown that non-sulfate particles (NSPs) are also present.

Geometrically Templated, Ultra‐Lightweight and High Strength Soap Films from Lyotropic Liquid Crystalline Graphene Oxide/Polymer Composites

open access: yesAdvanced Functional Materials, EarlyView.
Shellular materials form spontaneously by dip coating the primitive triply periodic minimal surface (TPMS) wireframe in an aqueous solution of lyotropic liquid crystalline graphene oxide (GO) nanosheets mixed with polymers. Regulated by surface tension, GO nanosheets align on the polymer soap film as the stress builds up during drying.

Balloon angioplasty of severe aortic coarctation in a newborn, using axillary artery access: The first experience in Turkey

open access: yesTürk Kardiyoloji Derneği Arşivi, 2016
Axillary artery access for demanding interventions in newborns is rarely described, in spite of the many clear advantages. This access route in newborns with critical congenital heart disease is a real alternative to the more commonly used femoral or ...

A BALLOON SPIDER [PDF]

open access: yesThe Canadian Entomologist, 1873
“The American Naturalist” for May, 1871, contains an interesting article on “Flying Spiders,” by J. H. Emerton. The species noticed by him are, no doubt, allied to the gossamer of Europe, and the phenomenon occurs early in autumn on the Islands of the St.

Functional Materials for Environmental Energy Harvesting in Smart Agriculture via Triboelectric Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

Gasless balloon laparoscopy [PDF]

open access: yesSurgical Endoscopy, 2009
The concept of balloon laparoscopy (B-LSC) pursues the simplification of conventional diagnostic laparoscopy (LSC). The pneumoperitoneum is replaced by a transparent balloon, which is positioned in front of the optical system. It shall be shown that with this arrangement diagnostic LSC can be performed outside of the operating room without requiring ...
