Flexibility and Dynamicity Enhances and Controls Supramolecular Self‐Assembly of Zinc(II) Metallogels

open access: yesAdvanced Functional Materials, EarlyView.
Zinc(II) coordination complexes with tunable aryloxy‐imine ligands exhibit controllable supramolecular self‐assembly into hierarchical fibrous structures. Coordination‐driven stacking, not π–π interactions, enables gelation, dynamic assembly/disassembly, and enhanced nanomechanical properties.

Knowledge-Based Discrete Optimalization of Truss Structures

open access: yesEngineering Transactions, 1995
The knowledge-based approach to discrete optimization is presented in the paper. The minimization problem characterized by linear objective function and arbitrary constraints is considered when design variables have to be chosen from a set of discrete ...

Integer Solutions of Integral Inequalities and 𝐻-Invariant Jacobian Poisson Structures

open access: yesAdvances in Mathematical Physics, 2011
We study the Jacobian Poisson structures in any dimension invariant with respect to the discrete Heisenberg group. The classification problem is related to the discrete volume of suitable solids.

Difference equation method for static problem of infinite discrete structures

open access: yesJournal of Civil Engineering and Management, 2002
The static problem of infinite, regular systems is considered. The structures are treated as discrete ones. The equilibrium conditions are derived using the FEM formulation.

Synergistic Osteogenesis After Co‐Administration of cmRNAs Encoding BMP‐2 and BMP‐7 Utilizing a Transcript‐Activated Matrix

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates that the dual delivery of BMP‐2/‐7 coding cmRNAs for bone healing is demonstrated as feasible, safe, and highly osteogenic. Compared to single BMP‐2 or BMP‐7 cmRNAs, the combination enhances the production of both mineral and organic components of the extracellular matrix when delivered using a collagen‐HA scaffold, supporting ...

Defect Analysis of the β– to γ–Ga2O3 Phase Transition

open access: yesAdvanced Functional Materials, EarlyView.
The role of defects at all the relevant stages of the β$\beta$‐ to γ$\gamma$‐Ga2O3 polymorph transition is investigated using a multi method approach. The positron annihilation spectroscopy based results show that the defect density decreases after the transition, and that changes in defect configuration within the γ phase occur with increasing ...

(Me4N)(NO2)2C6H3CO2 NEW MCl2 (M = Zn, Co, Cd) AND SnR3Cl (R = Me, Ph) ADDUCTS: SYNTHESIS AND INFRARED STUDY

open access: yesScientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2014
Five new (Me4N)(NO2)2C6H3CO2 adducts with MCl2 (M = Zn, Co, Cd) and SnR3Cl (R = Me, Ph) have been synthesized and studied by infrared spectroscopy. The suggested structures are discrete, the anion behaving as mono- and bichelating ligand towards MX2, tri-
