A gated strategy stabilizes room‐temperature phosphorescence

Aggregate, 2023
Room‐temperature phosphorescence (RTP) of purely organic materials is easily quenched with unexpected purposes because the excited triplet state is extremely susceptible to external stimuli.

Biological EXAFS at room temperature

Journal of Synchrotron Radiation, 1999
Biological EXAFS experiments are usually carried out on frozen samples in order to minimize radiation damage. This causes difficulties when studies at different pH are made, since the pH cannot be measured directly for the frozen sample. We have carried out EXAFS studies of Human Carbonic Anhydrase, a zinc metalloenzyme, at room temperature using a ...

Bloch oscillations at room temperature [PDF]

Physical Review B, 1995
We report on the observation of coherent electronic wave-packet oscillations in a semiconductor heterostructure at room temperature. Bloch oscillations are excited in a wide-miniband GaAs/${\mathrm{Al}}_{0.3}$${\mathrm{Ga}}_{0.7}$As superlattice by femtosecond laser pulses.

From LaH10 to room–temperature superconductors [PDF]

Scientific Reports, 2020
AbstractThermodynamic parameters of the LaH10 superconductor were an object of our interest. LaH10 is characterised by the highest experimentally observed value of the critical temperature: $${{\boldsymbol{T}}}_{{\boldsymbol{C}}}^{{\boldsymbol{a}}}={\bf{215}}$$TCa=215 K (pa = 150 GPa) and $${{\boldsymbol{T}}}_{{\boldsymbol{C}}}^{b}={\bf{260}}$$TCb=260 ...

Room-temperature chemical synthesis of C2

Nature Communications, 2020
Diatomic carbon (C2) is historically an elusive chemical species, considered to require high physical energy for its generation. Here, the authors describe the first room-temperature chemical synthesis of C2 and present experimental evidence for its ...

Effect of DFPP on Ferroptosis in Peripheral Blood CD14+ Monocytes of Hyperlipidemic Patients Involving the ACSL4/LPCAT3/ALOX5 Pathway

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Hyperlipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Although statins are the cornerstone of lipid‐lowering therapy, their use may be limited in some patients by adverse effects. This study evaluated the possible impact of non‐drug treatment using double‐filtration plasmapheresis (DFPP) on CD14+

Room-temperature processable amorphous Ga

Journal of Materiomics
Gallium oxide (Ga 2 O 3 )-based optoelectronic synapses are promising for solar-blind neuromorphic perception, yet their practical applications is currently hindered by energy consumption issues and the high fabrication temperature commonly required for ...
