Magnetic Control of the Manganese Photoluminescence in Fe3O4/l‑Cys ZnS:Mn Nanocomposites

Bibek Thapa, Shyam Sutariya, Mohammed Bsatee, Olesia A. Gololobova et autres

We investigated the magnetic control of the Mn photoluminescence (PL) in iron oxide/l-cysteine-capped zinc sulfide (Fe3O4/l-cys ZnS:Mn) nanocomposites via temperature- and field-dependent PL intensity studies. Fe3O4/l-cys ZnS:Mn was synthesized following a wet chemical deposition route and then its physicochemical, morphological, and magnetic …

Improving the Hydrophilicity of the Drugs Paclitaxel, Violacein, and Tetrandrine Using Carbon-Based Quantum Dots

Christine Wu, Katherine Ayala, Solimar Collazo-Hernandez, MiaSara Perez-Salvá et autres

Carbon-based quantum dots and their nitrogen- and sulfur-doped derivatives were used as platforms to improve the aqueous solubility for Paclitaxel, Violacein and Tetrandrine, drugs with known high partition coefficients (Log P). Paclitaxel, Violacein and Tetrandrine showed a significant reduction in their partition …

Chemical Vapor Deposition Synthesis of 3D Hybrid Carbon Materials at Low Pressure and Temperature

Carolina Rojas, Neida Santacruz, Frank Mendoza, Sebastián A. Michea et autres

A novel low-temperature method to synthesize a hybrid carbon material (HCM) is reported. The synthesis relies on a chemical vapor deposition (CVD) approach, using zeolite NaY as a scaffold structure and acetone as the carbon source. The deposition temperature was 500 °C …

Micro-Sized Tin Powders as a High-Capacity and Long-Cycling Alloy Anode for Sulfide-Based All-Solid-State Lithium-Ion Batteries

Irfan Ullah, Xiaoyu Du, Wentao Hou, Songyang Chang et autres

Abstract The development of high-capacity and long-cycling anodes is essential for advancing sulfide-based all-solid-state lithium-ion batteries (ASSLIBs). Among various candidates, tin (Sn) metal is a promising alloy anode, due to its high capacity, low cost, and high conductivity. However, previous studies mostly …

Halide-Based Solid Electrolytes for Advanced All-Solid-State Batteries: Design, Interfaces, and Electrochemical Performance

Shivaraju Guddehalli Chandrappa, Gerardo Morell, Ram S. Katiyar

Halide-based solid electrolytes (HSEs) have garnered substantial interest for all-solid-state batteries (ASSBs) due to their wide electrochemical windows, moderate-to-high room-temperature ionic conductivity, and enhanced air stability over traditional sulfide and oxide-based SEs. This review consolidates recent advances in HSEs, focusing on the …

A Rechargeable Zinc–Copper Voltaic Battery Built from Cost-Effective Electrodes and Electrolytes

José Fernando Flórez Gómez, Songyang Chang, Irfan Ullah, Juan C. Velez Reyes et autres

The zinc–copper (Zn-Cu) voltaic battery is the first battery made in human history, but the Cu2+ dissolution issue leads to the reaction’s irreversibility. To tackle this challenge, solid-state electrolytes, ion exchange membranes, and functional electrolytes have been proposed to mitigate the Cu2+ …

Manipulating electrolyte solvation structures to build high-voltage concentration batteries for efficient energy storage

Wentao Hou, Zhilong Wang, Songyang Chang, Irfan Ullah et autres

Concentration batteries represent a distinctive type of Galvanic cells that use the same redox couple at both electrodes but generate voltage from differences in electrolyte compositions. However, their applications have been limited because ten times concentration difference typically produces only small voltages …
