Forest typological structure of oak forests of volyn height

open access: yesForestry, Forest, Paper and Woodworking Industry, 2018
Oak (Quercus robur L.) is one of the most common and valuable tree species in the Western Forest-Steppe of Ukraine. Much of the oak forests of the Western Forest-Steppe are concentrated in the forest district of Volyn Upland, which, despite belonging to the Western Ukrainian Forest-Steppe Forest District, is characterized by special geomorphological ...

Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.

Advancing Research on Biomaterials and Biological Materials with Scanning Electron Microscopy under Environmental and Low Vacuum Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...
