Cooling and societal change during the Late Antique Little Ice Age from 536 to around 660 AD
Climatic changes during the first half of the Common Era have been suggested to play a role in societal reorganizations in Europe (1,2) and Asia (3,4). In particular, the sixth century coincides with rising and falling ...
Restructuring of plasmonic nanoparticle aggregates with arbitrary particle size distribution in pulsed laser fields
We have studied processes of interaction of pulsed laser radiation with resonant groups of plasmonic nanoparticles (resonant domains) in large colloidal nanoparticle aggregates having different interparticle gaps and ...
Woody biomass production lags stem-girth increase by over one month in coniferous forests
Wood is the main terrestrial biotic reservoir for long-term carbon sequestration1, and its formation in trees consumes around 15% of anthropogenic carbon dioxide emissions each year2. However, the seasonal dynamics of woody ...
Triple molybdate scheelite-type upconversion phosphor NaCaLa(MoO4)3:Er3+/Yb3+: structural and spectroscopic properties
Triple molybdate NaCaLa(1-x-y)(MoO4)3:xEr3+,yYb3+ (x = y = 0, x = 0.05 and y = 0.45, x = 0.1 and y = 0.2, x = 0.2 and y = 0) phosphors were successfully synthesized by the microwave sol-gel method for the first time. ...
Microwave Sol–Gel Synthesis of CaGd2(MoO4)4:Er3+/Yb3+ Phosphors and Their Upconversion Photoluminescence Properties
CaGd2(MoO4)4:Er3+/Yb3+ phosphors with the doping concentrations of Er3+ and Yb3+ (x = Er3+ + Yb3+, Er3+ = 0.05, 0.1, 0.2, and Yb3+ = 0.2, 0.45) have been successfully synthesized by the microwave sol–gel method, and the ...
Reflective Power Limiter for X-band with HTSC switching element
his paper presents a new type of power limiter (PL), using superconducting – to – normal state phase transition in HTSC. The presented device differs from the existing ones mainly in the ...
Optimization of photothermal methods for laser hyperthermia of malignant cells using bioconjugates of gold nanoparticles
Selective action of laser radiation on membranes of malignant cells has been studied in different regimes using conjugates of gold nanoparticles with oligonucleotides by the example of DNA aptamers. Under the ...
