The effect of Ta oxygen scavenger layer on HfO$_2$-based resistive switching behavior: thermodynamic stability, electronic structure, and low-bias transport [PDF]

, 2016
Reversible resistive switching between high-resistance and low-resistance states in metal-oxide-metal heterostructures makes them very interesting for applications in random access memories. While recent experimental work has shown that inserting a metallic "oxygen scavenger layer" between the positive electrode and oxide improves device performance ...

Changing the properties of Hf$_{0.5}$Zr$_{0.5}$O$_{2}$ during cyclic repolarization of ferroelectric capacitors with different electrode materials [PDF]

arXiv, 2022
The interest in the ferroelectric non-volatile memory as a candidate for low power consumption electronic memories was raised after the discovery of ferroelectricity in hafnium oxide. Doping by different elements of hafnia films allows improving their ferroelectric properties. In this work, the transport experiments are combined with the simulations to

Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments

FEBS Open Bio, EarlyView.
Photosynthesis faces challenges from environmental extremes of temperature, pH, and salinity, limiting gas diffusion, modifying membrane fluidity, and destabilizing photochemical and biochemical reactions. Photosynthetic organisms have evolved unique adaptations overcoming these stresses and maintaining their photosynthetic activity.

Iron‐dependent lysosomal LDL oxidation induces the expression of scavenger receptor A in human THP‐1 monocytes

FEBS Open Bio, EarlyView.
In human monocytic cells THP‐1, a limited uptake of native—not oxidized—LDL/VLDL induced expression of scavenger receptor A and cellular adhesion. Induction was inhibited by lysosomotropic (WR‐1065) and lipophilic (BHT) antioxidants and by siRNAs against ferritinophagy.

Arsenic trioxide treatment decreases the oxygen consumption rate of tumor cells and radiosensitizes solid tumors.

Cancer Research, 2012
Arsenic trioxide (As(2)O(3)) is an effective therapeutic against acute promyelocytic leukemia and certain solid tumors. Because As(2)O(3) inhibits mitochondrial respiration in leukemia cells, we hypothesized that As(2)O(3) might enhance the ...

Intracellular oxygen tension limits muscle contraction-induced change in muscle oxygen consumption under hypoxic conditions during Hb-free perfusion. [PDF]

, 2017
Under acute hypoxic conditions, the muscle oxygen uptake (mV˙O2) during exercise is reduced by the restriction in oxygen-supplied volume to the mitochondria within the peripheral tissue. This suggests the existence of a factor restricting the mV˙O2 under

Profiling the effect of low frequency mechanical vibration on the metabolic and oxidative stress responses of A431 carcinoma

FEBS Open Bio, EarlyView.
20 Hz mechanical vibration induced A431 cancer cells' apoptosis without such effect on other healthy cell lines of L929 and C2C12. Lowered glucose consumption is observed specifically in A431. The expressions of ROS, HMGB1, and HSP1 levels initially increase and subsequently decrease in the cancer cell line, as opposed to L929 and C2C12, which ...
