Spacer-Dependent and Pressure-Tuned Structures and Optoelectronic Properties of 2D Hybrid Halide Perovskites [PDF]
, 2023 Compared with their 3D counterparts, 2D hybrid organic–inorganic halide perovskites (HOIPs) exhibit enhanced chemical stabilities and superior optoelectronic properties, which can be further tuned by the application of external pressure.

The Effect of Bottom Reinforcement Spacers on Reinforced Concrete Structures Loaded by Explosion
Buildings, 2023 Plastic spacers create a linear and systemic weakening of the structure. The extreme loading of the structure tests the structure itself to its load-bearing limit or even locally exceeds this limit, thus revealing all its weak points, which are the ...

Spacer-Mediated Control of Coumarin Uncaging for Photocaged Thymidine [PDF]
, 2020 Despite its importance in the design of photocaged molecules, less attention is focused on linker chemistry than the cage itself. Here, we describe unique uncaging properties displayed by two coumarin-caged thymidine compounds, each conjugated with (2 ...

Spacer devices in asthma [PDF]
Thorax, 2000 The British guidelines on asthma management and other recent reviews have widely advocated the use of spacer devices for asthmatic patients.1-3 Spacer devices allow aerosol to be inhaled through a valved mouthpiece during a single inspiratory breath or as is often recommended for children during tidal breathing.2During the expiratory phase of a tidal ...
