Advanced Science, EarlyView.A cation‐anion synergistic strategy is developed to enhance self‐assembled monolayer (SAM) adsorption using guanidinium thiocyanate (GuaSCN). Guanidinium (Gua⁺) suppresses micelle aggregation, while thiocyanate (SCN−) promotes phosphonic acid deprotonation and strengthens ionic bonding to the substrate.

Advanced Science, EarlyView.ABSTRACT Strain is a proven technique for modifying the bandgap and enhancing carrier mobility in 2D materials. Most current strain engineering techniques rely on the post‐growth transfer of these atomically thin materials from growth substrates to target surfaces, limiting their integration into nanoelectronics.

What would have happened to the ozone layer if chlorofluorocarbons (CFCs) had not been regulated? [PDF]
Atmospheric Chemistry and Physics, 2009 Ozone depletion by chlorofluorocarbons (CFCs) was first proposed by Molina and Rowland in their 1974 Nature paper. Since that time, the scientific connection between ozone losses and CFCs and other ozone depleting substances (ODSs) has been firmly ...

Chemical ozone loss and chlorine activation in the Antarctic winters of 2013–2020 [PDF]
Atmospheric Chemistry and PhysicsThe annual formation of an ozone hole in the austral spring has regional and global climate implications. The Antarctic ozone hole has already changed the precipitation, temperature and atmospheric circulation patterns, and thus the surface climate of ...

Decending motion of particle and its effect on ozone hole chemistry [PDF]
Particle descending motion is one possible process which causes ozone loss near the tropopause in the Antarctic spring. However, this particle size distribution has not yet been measured.

The artificial method of the ozone layer restoration [PDF]
, 2007 The problem of the ozone holes became known for mankind at the 80-th years last century. Ozone loss was first detected in the stratosphere over Antarctica. In 1985, Vienna Conception related to the ozone layer protection was proclaimed.

Ion Crowding Effect in Unilaterally Downsized Perovskite Memristors
Advanced Science, EarlyView.The downscaling of perovskite memristors incorporating monocrystalline nanoplates is accompanied by an ion crowding effect, which greatly enhances the local electric field in the vicinity of electrode. The highly controlled crowding of anions and vacancies results in anisotropic switching characteristics as well as unique morphology modification ...
