Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

open access: yesAdvanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

Alkaline stress transforms Madin-Darby canine kidney cells

Pfl�gers Archiv European Journal of Physiology, 1991
Similar to growth factors aldosterone stimulates Na+/H+ exchange in renal target cells leading to cytoplasmic alkalinization. An alkaline intracellular pH reduces the H+ bonds between repressor proteins and DNA leading to the destabilization of the nuclear chromatin.

Comprehensive physiological, transcriptomic, and metabolomic analysis of the response of Panicum miliaceum L. roots to alkaline stress

Land Degradation & Development, 2023
Alkaline stress disrupts transcriptional expression and causes metabolite accumulation, thus affecting plant growth. However, there are gaps in the response mechanism of plants to alkaline stress at the molecular dimension.

Alkaline Stress-Induced Cell Transformation

Physiology, 1994
Sustained alkalosis transforms epithelial cells in culture. Genotypically altered cells express an endogenous Ca2+ oscillator that probably is the motor for restless locomotion of these cells. Atomic force microscopy discloses membrane turnover processes during cell migration at the nanometer level.

Comparative Proteomic Analysis of Two Wild Soybean (Glycine soja) Genotypes Reveals Positive Regulation of Saline-Alkaline Stress Tolerance by Tonoplast Transporters.

Journal of Agricultural and Food Chemistry, 2023
Soil saline-alkalization is a significant constraint for soybean production. Owing to higher genetic diversity of wild soybean, we compared the proteomic landscape of saline-alkaline stress-tolerant (SWBY032) and stress-sensitive (SWLJ092) wild soybean ...
