Atomistic investigation of the wear of nanoscale diamond cutting tools shaped by focused ion beam [PDF]

open access: yes, 2016
In recent years, micro/nanoscale diamond cutting tools shaped by focused ion beam (FIB) has been developed to the deterministic fabrication of micro/nano-structures owing to its unprecedented merits of high throughput, one-step, and highly flexible ...

Catalytic TiO2 with Self‐Assembled Monolayer for Highly Sensitive, Selective, and Non‐Invasive Monitoring of Sweat L‐Cysteine

open access: yesAdvanced Functional Materials, EarlyView.
A self‐assembled monolayer of 3‐mercaptopropyltrimethoxysilane (MPTS) molecular receptor and titanium oxide‐modified carbon cloth (MPTS/TiO2/CC) was synthesized for the specific detection of sweat L‐cysteine, which is associated with the precision neutrition, cardiovascular system and neuro system.

Energetic aspects of boring tools wear [PDF]

open access: yes, 2002
In the process of rock desintegration a boring tool is subjected to the wear. From a viewpoint of the bit wear, changes on the contact of operating tool with rock at its one-shot and rerun load or overload by external forces are technically significant ...

Sensing of Chloride Ions in Sweat by Means of Printed Extended‐Gate Organic Electrochemical Transistors

open access: yesAdvanced Functional Materials, EarlyView.
In this work, a platform based on an Extended‐Gate OECT is successfully developed and tailored for the detection of physiologically relevant chloride ion concentrations in artificial eccrine sweat. Leveraging the extended‐gate architecture, a high‐performance OECT based on inkjet‐printed pg2T‐TT is coupled with an inkjet‐printed Ag/AgCl electrode ...

Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

Cat‐Vibrissa‐Inspired Biomass Fiber Aerogels for Flexible and Highly Sensitive Sensors in Monitoring Human Sport

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by cat vibrissae, biomimetic biomass PHFs/SA aerogels (BFAs) are developed via precursor‐assisted in situ polymerization and freeze‐synergistic assembly. These ultralight, porous pressure sensors exhibit high sensitivity and excellent durability, enabling pulse detection, handwriting recognition, Morse code transmission, and notably real‐time ...
