Article Abstract
The voltage dependence of the dielectric permittivity ' and the low dielectric loss tan of incipient ferroelectrics have drawn vast attention to the use of these materials for the development of tuning elements in electronics and telecommunications. Here, we study the DC electric field dependence of low-temperature ' in ~320 nm thick sol-gel-derived SrTiZnO thin films with x = 0.01 and 0.05, deposited on Pt/TiO/SiO/Si substrates. Incorporation of Zn onto Ti sites is found to decrease ' compared to undoped SrTiO films, while increasing the relative tunability up to ~32.9% under a DC electric field of 125 kV/cm at low temperatures. The hysteresis-free variation in ' with electric field and tan values below 0.6% observed for SrTiZnO film with x = 0.01 make this compound more attractive for tunable device applications.

This study evaluated the modification of corn starch using low-intensity pulsed electric field (PEF: 10 kV) combined with sodium salts (NaCl, NaCO₃, NaH₂PO₄) to investigate how pH and increased electrical conductivity affect starch structure. The study examined how salt pH and increased conductivity from electronegativity differences enhance polymer structural changes. NaCO₃ reduced amylose and long amylopectin chains (DP ≥ 37) by 18 %, confirmed by hydrodynamic radius (Rh) reductions for amylose (3.

Objective: Skin cancer is widely recognized as one of the most perilous diseases on a global scale. Early identification of skin lesions can significantly enhance the treatment effects by aiding in clinical decision-making, hence mitigating the risk of disease progression and metastasis. Unfortunately, the skin images used for training are usually limited and imbalanced.

The offshore renewable energy industry is expanding rapidly due to decarbonisation commitments and need for energy security. This will change the marine environment in ways that are not fully understood, including more subsea power cables in the sea. Movement of electricity through these cables generates an electromagnetic field (EMF), which might affect marine species.

The polysulfide shuttling and sluggish sulfur redox kinetics hinder the commercialization of lithium-sulfur (Li-S) batteries. Herein, the fabrication of phosphorus (P)-doped iron telluride (FeTe) nanoparticles with engineered Te vacancies anchored on nitrogen (N)-doped carbon (C) (P-FeTe@NC) is presented as a multifunctional sulfur host. Theoretical and experimental analyses show that Te vacancies create electron-deficient Fe sites, which chemically anchor polysulfides through enhanced Fe─S covalent interactions.
