The reductive desorption of 2-aminoethanethiol (AET) monolayers formed on a polycrystalline gold electrode has been studied using cyclic voltammetry. Three cathodic peaks were observed and they were assigned to reductive desorption from each small domain of Au(111), (100), and (110) over the polycrystalline surface. The kinetics of adsorption were likely under the condition where the kinetic control and the diffusion control were balanced over the concentration range 5-50 μM (M = mol dm −3), whereas it was described by the kinetic control model at 100 μM. The thermodynamics of adsorption was well-described by the Langmuir isotherm. The saturation surface coverage was found to be 5.3 × 10 −10 mol cm −2 , which suggested that AET adsorbed lying flat on a polycrystalline gold electrode.

“…Glucose is an inexpensive biosourced fuel that for some years has been used for the development of glucose–oxygen biofuel cells, microbial fuel cells, and glucose biosensors for the diagnosis of diabetes mellitus . Besides enzymes and microbes, one way to catalyze the glucose oxidation reaction is directly on metallic electrodes linked with nanoparticles (NPs).…”

One‐Pot Route to Gold Nanoparticles Embedded in Electrospun Carbon Fibers as an Efficient Catalyst Material for Hybrid Alkaline Glucose Biofuel Cells

Traditional strategies to develop Au metal nanoparticle catalysts for glucose oxidation comprise Au nanoparticles (NPs) supported on electrode surfaces. In this work, the fabrication of a new material capable of acting as an abiotic anode for the electrooxidation of glucose was developed. The material is composed of electrospun carbon fibers containing gold nanoparticles formed in situ from a polyacrylonitrile (PAN) solution with HAuCl4. This approach allows the pre‐reduction of the gold salt by PAN under mild conditions without the need for extra energy and leads to very stable carbon–gold bonding with well‐dispersed AuNPs, not previously reported. The gold‐modified carbon fibers (Au@CFs) were characterized by SEM, energy‐dispersive X‐ray spectroscopy, XRD, and electrochemical analysis. The Au@CF electrodes showed electrochemical activity toward glucose oxidation in alkaline media. Combined to a bilirubin oxidase modified biocathode (BOD@CFs), the resulting hybrid glucose biofuel cell showed open‐circuit voltage and power density values of 0.75 V and 65 μW cm−2, respectively, which remained intact after 3 weeks.

“…12 Indeed, a high specific surface area leads to larger accessible amounts of enzymes being immobilized on the electrode surface, which is directly linked to the current densities delivered by biofuel cells. Moreover, the high electrical conductivity of the electrodes is crucial for the transport of electrons generated by biocatalytic reactions 13–15…”

Synthesis, Persistent Luminescence, and Thermoluminescence Properties of Yellow Sr₃SiO₅:Eu²⁺,RE³⁺ (RE=Ce, Nd, Dy, Ho, Er, Tm, Yb) and Orange‐Red Sr_3−xBa_xSiO₅:Eu²⁺, Dy³⁺ Phosphor

Sunlight-excitable orange or red persistent oxide phosphors with excellent performance are still in great need. Herein, an intense orange-red Sr3-xBaxSiO5:Eu(2+),Dy(3+) persistent luminescence phosphor was successfully developed by a two-step design strategy. The XRD patterns, photoluminescence excitation and emission spectra, and the thermoluminescence spectra were investigated in detail. By adding non-equivalent trivalent rare earth co-dopants to introduce foreign trapping centers, the persistent luminescence performance of Eu(2+) in Sr3SiO5 was significantly modified. The yellow persistent emission intensity of Eu(2+) was greatly enhanced by a factor of 4.5 in Sr3SiO5:Eu(2+),Nd(3+) compared with the previously reported Sr3SiO5:Eu(2+), Dy(3+). Furthermore, Sr ions were replaced with equivalent Ba to give Sr3-xBaxSiO5 :Eu(2+),Dy(3+) phosphor, which shows yellow-to-orange-red tunable persistent emissions from λ=570 to 591 nm as x is increased from 0 to 0.6. Additionally, the persistent emission intensity of Eu(2+) is significantly improved by a factor of 2.7 in Sr3-xBaxSiO5 :Eu(2+),Dy(3+) (x=0.2) compared with Sr3SiO5 :Eu(2+),Dy(3+). A possible mechanism for enhanced and tunable persistent luminescence behavior of Eu(2+) in Sr3-xBaxSiO5:Eu(2+),RE(3+) (RE=rare earth) is also proposed and discussed.
