Advanced Functional Materials, EarlyView.Solution‐based ligand‐assisted epitaxial growth (LAEG) yields high‐quality CsPbBr3 microcrystals on different substrates with superior morphology, passivated surfaces, and high photoluminescence quantum yield. These robust micro‐resonators achieve record‐low room‐temperature lasing thresholds of 7.2 kW·cm−2 and maintain operational stability up to 90 ...

Magneto‐Ionic Devices With Polymer‐Based Electrolytes
Advanced Functional Materials, EarlyView.Polymer electrolytes are introduced for magneto‐ionic devices based on hydroxide and hydrogen ions. The magneto‐ionic effect results in a pronounced voltage‐controlled variation of coercivity in both devices. The switching speed is in the range of 100 ms.

Advanced Functional Materials, EarlyView.For the first time, an extreme‐thick laser‐arc PVD ta‐C (DLC) coating exceeding 100 µm is demonstrated, opening up new possibilities for ultra‐high load bearing capacity. This superhard amorphous carbon architecture combines >50% sp3 bonding, robust adhesion and self‐supporting performance, shielding substrates from plastic flow under extreme contact ...

Layer by layer nanoarchitectures for the surface protection of polycarbonate
European Polymer Journal, 2013Abstract The layer by layer (LbL) technique has been exploited for depositing a completely inorganic silica coating on 0.2 and 1 mm thick polycarbonate (PC) films. The modification of the surface of the polymer substrate has been assessed by contact angle measurements, SEM and FT-IR analyses.

Introduction to layers of protection analysis
Journal of Hazardous Materials, 2003Layers of protection analysis (LOPA) is a powerful analytical tool for assessing the adequacy of protection layers used to mitigate process risk. LOPA builds upon well-known process hazards analysis techniques, applying semi-quantitative measures to the evaluation of the frequency of potential incidents and the probability of failure of the protection ...

Circuit World, 2003
AbstractOffers the first comprehensive history of international efforts to protect the ozone layer by abandoning the use of chlorofluorohydrocarbons (CFCs), and underlines that this is the greatest success yet achieved in managing human impacts on the global environment.

Protectiveness of Corrosion Layers
1994This paper summarizes the experimental and theoretical evidence showing that, in permanent immersion, the protectiveness of corrosion layers can only be due to diffusional transport phenomena in the liquid phase. This gives rise to the new concept of a “liquid surface state”.

THE PROTECTIVE LAYERS OF THE APPLE
Canadian Journal of Research, 1937The development of the four protective layers of the apple, namely the hairs, cuticle, epidermis and hypodermis, is described in detail, from the time the flower emerges from the winter bud early in May, until harvest time early in October. The gradual loss of living and active cell contents is recorded for each layer.
