X-ray microtomography study of carious dentine and a comparison of its removal by three techniques

, 2010
The wisdom on mechanical removal of carious dentine based on hardness has been challenged and chemo-mechanical technique has been proposed as a more conservative method.

Formation of Quasi‐Decoupling Interface on Li‐Metal Anodes in High Donor Electrolyte

Advanced Functional Materials, EarlyView.
Li‐metal anode (LMA) is stabilized by introducing Li2Te2 as an electrolyte additive for Li‐metal batteries. Upon contact with Li, Li2Te2 spontaneously converts to Li2Te, which electronically isolates Li from dimethyl sulfoxide due to its large bandgap and minimal Bader charge transfer.

Lubricant Additives for Improving the Performance of Metal V-Belt Type CVTs

Tribology Online, 2012
Lubricants for metal V-belt type CVTs (B-CVTFs) must be able to produce a higher metal-metal friction coefficient and give excellent anti-shudder properties for lock-up clutch used in B-CVTs.

AFM-IR images of the four spectroscopic parameters acquired on the same area of a cancellous bone sample.

, 2018
Maps were derived from images acquired at six wavenumbers: 1128 cm-1, 1096 cm-1, 1030 cm-1, 1020 cm-1 (mineral band), 1690 cm-1, and 1660 cm-1 (amide). Those maps, particularly the mineral-to-matrix ratio and the collagen crosslink ratio, show layers of ...

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

Interactive Strength between C60 Thin Film and Si(001) and Its Influence on Nano-Scaled Tribology

Tribology Online, 2008
The influences of interactions between C60 thin films and Si substrates were investigated using atomic force microscopy (AFM). It was found that higher friction coefficient was obtained at the C60 domains formed on the H-terminated Si(001) substrate and ...

Charge storage in mesoscopic graphitic islands fabricated using AFM bias lithography

, 2011
Electrochemical oxidation and etching of highly oriented pyrolytic graphite (HOPG) has been achieved using biased atomic force microscopy (AFM) lithography, allowing patterns of varying complexity to be written into the top layers of HOPG.
