An operational windmill in an open-air museum as a conservation challenge: Lessons from projects recently implemented in Poland [PDF]

open access: yesMuzeológia a Kultúrne Dedičstvo
The article discusses the methods of protecting historic windmills and recognising them as valuable objects of industrial heritage. Therefore, examples of attempts to restore windmills as working mills after 2010 are discussed.

Extraordinary n‐type Tellurium‐Free Thermoelectric Performance of Y‐Doped BiSe via Synergistic Effect of Vacancies and Band Engineering

open access: yesAdvanced Functional Materials, EarlyView.
Yttrium doping in Sb‐alloyed BiSe synergistically induces Bi vacancies and flattens conduction bands, simultaneously slashing lattice thermal conductivity by 50% and boosting the power factor. The optimized n‐type Bi0.64Sb0.3Y0.06Se delivers a peak zT of 0.91 at 393 K (average zT 0.76, 300–523 K) and an 8‐pair module with 4.6% conversion efficiency ...

Giant Electrostriction in Halide Perovskites Revisited With Double‐Modulation Interferometry

open access: yesAdvanced Functional Materials, EarlyView.
A giant electrostrictive effect in lead halide perovskites had been reported previously. This work uses sensitive interferometry to measure the electromechanical response of various halide perovskite samples. The results reveal no intrinsic electrostrictive compression. Instead, the materials expand primarily under an applied electric field as a result

Operational analysis of electric field mills as lightning warning systems in Colombia

open access: yes2012 International Conference on Lightning Protection (ICLP), 2012
Electrostatic field measurements obtained in Bogota-Colombia during thunderstorm episodes in November (common raining season due to the intertropical confluence zone over central Colombia) were used to study the performance of an isolated electric field sensor and analyze its most important operational characteristics.

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...
