Investigating Prevalence, Induction, and Fertility of Polyploid Rhododendron L. and the Development of Protocols for Vegetative Propagation

open access: yes, 2008
Studies were conducted to determine the ploidy levels of specific Rhododendron taxa, to develop a simple and effective ex-vitro method for inducing polyploidy in Rhododendron seedlings, and to evaluate the effect of increased ploidy level on pollen ...

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

open access: yesAdvanced Engineering Materials, EarlyView.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

open access: yesAdvanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Propagation of Taxus baccata 'Green Diamond' by cutting [PDF]

open access: yes, 2016
Buxus sempervirens and its varieties, such as ’Suffruticosa’, are popular plants of historic as well as modem gardens. The box tree moth (Cydalima perspectalis), one of its most aggressive pests, also appeared in Hungary in 2011.

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

open access: yesAdvanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...
