Nanoscale silver: Thin-film structure and antimicrobial functionality [PDF]

open access: yes, 2012
Since antiquity, silver has been used as a material to reduce spoilage. Over the past decades, there has been an increasing scientific and commercial interest in developing silver surfaces due to the increasing number of drug resistant microorganisms. In

SILVER-BEARING DEPOSITS OF THE URALS

open access: yesUral Historical Journal
This article explores a little-studied topic of polymetallic ore mining and silver extraction in the Urals. In Russian historiography, the prevailing view is that silver was not mined here. Amid large-scale gold mining of the 19th century, silver faded into the background and was virtually forgotten. However, ores containing precious metals were sought

Programming Nanoscale Reaction Environments via Peptide Localization for Gold Nanoparticle Growth in Liposomal Nanoreactors

open access: yesAdvanced Functional Materials, EarlyView.
The liposome nanoreactor method enables uniform metal nanoparticle synthesis using the interior as a reaction environment. We demonstrate that peptide sequences and lipid compositions act as a functional molecular switch to control reaction environments in liposome nanoreactors.

Bio‐Inspired Artificial Ionic Mechanoreceptor

open access: yesAdvanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

Reservoir‐Driven Neuromorphic Computing Based on Composite Rare‐Earth/Transition Metal Oxide Memristor

open access: yesAdvanced Functional Materials, EarlyView.
A defect‐engineered Ag/Gd2O3:Nb2O5/Pt rare earth composite oxide memristor enables stable multilevel reservoir states through pulse driven conductance modulation. Experimentally measured device responses are incorporated into a device aware reservoir computing framework for CIFAR‐100 image classification, highlighting the potential of rare earth ...

Silver inhibition on recombinant flavin reductase from Citrobacter freundii A1 [PDF]

open access: yes, 2012
In this study, the flavin reductase (Fre) of Citrobatter freundii A1 was expressed in E. coli DH5a host with 1 mM IPTG induction. This recombinant protein was fused to 6xHis-tag, thus promising easier IMAC purification of the expressed enzyme.

Kinetics‐Controlled Architecture of Binder‐Free Organic Electrodes for Enhanced Ion Transport

open access: yesAdvanced Functional Materials, EarlyView.
Pulse reverse electrodeposition controls nucleation and growth to create hierarchically porous Py‐derived oligomeric electrodes with enhanced ionic accessibility and reduced transport resistance. The resulting binder‐free architectures translate these transport advantages into practical sodium‐storage functionality.

Manganese deposits of the Cape Peninsula, South Africa [PDF]

open access: yes, 2013
The outcrops, petrography and geochemistry of manganese deposits were studied at several sites on the Cape Peninsula (Skeleton Gorge, Kasteelpoort Path, Kommetjie and Hout Bay) as well as at Rooi Els on the opposite side of False Bay.
