Asymmetry of the Ferroelectric Phase Transition in BaTiO3

Advanced Materials, EarlyView.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

Parametrical Functioning Study for a Small Boiler Condensing Unit

Energy Procedia, 2017
Abstract Considering the actual concern for reducing the fuel consumption along with pollution reduction, the condensing boilers get a major importance for the manufacturers, mainly for the household heating domain. In the context, more and more small boilers producers shift their non-condensing units to condensing units.

Rewriting Polymer Fate via Chemomechanical Coupling

Advanced Materials, EarlyView.
This work introduces a life‐like “living” polymer platform that can grow, degrow, and reprogram its properties after fabrication. By integrating mass transport, reversible polymerization, and controlled catalysis, the material achieves on‐demand changes in size, shape, and mechanical properties.

Arm‐Length‐Controlled CsPbBr3 Nanocrystals for Tunable Optical and Assembly Behavior

Advanced Materials, EarlyView.
In this work, the synthesis parameters that dictate the formation of armed CsPbBr3 nanocrystals are described, and routes enabling precise control over arm length are proposed. Direct links between morphology and optoelectronic behavior are established.

Nonlinear Boiler-Turbine Unit: Modelling and Robust Decentralized Control

IFAC-PapersOnLine, 2016
Abstract Efficient control of a boiler-turbine unit is of great importance not only in power plants. In this paper, a linearized model is developed for a nonlinear Multi Input-Multi Output model (MIMO) of a utility boiler-turbine unit and a decentralized robust controller is designed.
