Experience in developing sine-wave filter for power circuit of VVVF-drive with induction motor
The relevance of the work reflects the increased use in domestic practice of variable frequency electric drive additional options, which include sine-wave filter; the demand for development of sine-wave filters based on domestic components.

Electric capacitance as nanocondensers in zigzag nanographite ribbons [PDF]
Electronic states in nanographite ribbons with zigzag edges are studied using the extended Hubbard model with nearest neighbor Coulomb interactions. The nearest Coulomb interactions stabilize electronic states with the opposite electric charges separated

Origin of apparent light-enhanced and negative capacitance in perovskite solar cells
So-called negative capacitance seems to remain an obscure feature in the analysis of the frequency-dependent impedance of perovskite solar cells. It belongs to one of the puzzling peculiarities arising from the mixed ionic-electronic conductivity of this

Chromatin, which organizes DNA, changes its structure to adapt to stress like high oxygen levels (hyperoxia), which can damage cells. Researchers developed a technique to observe these changes and found variability in how different parts of chromatin remodel.

Transformerless Common-Mode Current-Source Inverter Grid-Connected for PV Applications
The use of a transformer in grid-connected photovoltaic (PV) generation systems provides isolation between the grid and the PV array, this increases the cost, weight, and the size of the system.

Dielectric properties of Raphia Fiber from Epidermis of young Raphia Vinifera leaflet
There are materials that could serve useful purpose(s) in many fields, but they are left unutilized due to lack of both the knowledge on their useful properties and availability of values as per such properties.

Direct Observation of Josephson Capacitance [PDF]
The effective capacitance has been measured in the split Cooper pair box (CPB) over its phase-gate bias plane. Our low-frequency reactive measurement scheme allows to probe purely the capacitive susceptibility due to the CPB band structure.

Activation of NF‐κB Signaling by Optogenetic Clustering of IKKα and β
This study presents an optogenetic approach for graded clustering of eGFP‐fused proteins using an eGFP‐specific nanobody and engineered Cryptochrome 2 variants. The method enables potent, reversible activation of NF‐κB signaling via endogenous pathways, as confirmed by RNA sequencing. This versatile system provides a spatially and temporally controlled
