Rapid and controlled electrochemical synthesis of crystalline niobium oxide microcones [PDF]

open access: yes, 2015
We demonstrate the fabrication by anodization of niobium oxide microcones, several microns long, from aqueous solutions of 1 wt% hydrogen fluoride (HF) with varied sodium fluoride (NaF) concentration (0–1 M).

Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Boron Neutron Capture Therapy at a Crossroads: Translational Gap and Emerging Delivery Agents

open access: yesChemistry – A European Journal, EarlyView.
This review surveys recent advances in boron delivery agents for BNCT, emphasizing the shift from classical small molecules to multifunctional nanocarriers and theranostic systems. By integrating targeting, imaging, and therapy, next‐generation boron compounds aim to bridge the gap between (bio)chemical innovation and clinical translation.

Integration of High‐p, Low‐T CO2 Electrolysis with Pressure Swing Adsorption Purification

open access: yesChemie Ingenieur Technik, EarlyView.
We evaluate a high‐p low‐T CO2 electrolysis (LTCE) cell with a pressure swing adsorption (PSA) to compare cascade vs. recycle operation. Although a cascade yields high CO selectivity but limited yield, a full recycle achieves near‐quantitative CO production, highlighting gas recycling as essential for LTCE/PSA systems.

Surface composition of BaTiO3/SrTiO3(001) films grown by atomic oxygen plasma assisted molecular beam epitaxy

open access: yes, 2012
We have investigated the growth of BaTiO3 thin films deposited on pure and 1% Nb-doped SrTiO3(001) single crystals using atomic oxygen assisted molecular beam epitaxy (AO-MBE) and dedicated Ba and Ti Knudsen cells.

Water electrolysis on La1−xSrxCoO3−δ perovskite electrocatalysts [PDF]

open access: yes, 2015
Perovskite oxides are attractive candidates as catalysts for the electrolysis of water in alkaline energy storage and conversion systems. However, the rational design of active catalysts has been hampered by the lack of understanding of the mechanism of ...

No Charging but Protection: Lifetime Prolongation of Spontaneously‐polarized Electrets for Energy Harvesting Applications

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A bilayer protection approach is proposed for slowing down the surface potential decay of thin films of spontaneously‐polarized electret materials. The electret and the protective films are characterized, and the protection effectiveness is investigated under the effects of light illumination, water contact and mechanical impact.
