Although contact electrification (triboelectrification)(CE) has been documented since 2600
years ago, its scientific understanding remains inconclusive, unclear, and un-unified. This …

Calculations of the impact of friction and wear on energy consumption, economic
expenditure, and CO 2 emissions are presented on a global scale. This impact study covers …

Although the contact electrification (CE)(or usually called'triboelectrification') effect has been
known for over 2600 years, its scientific mechanism still remains debated after decades …

The peeling apart of layered materials is common in nature and has been used by humans
in myriad applications since prehistoric times. Over the past century, a wide range of peel …

Long-term observation of the triboelectric effect has not only proved the feasibility of many
novel and useful tribo-devices (eg, triboelectric nanogenerators), but also constantly …

Here we introduce a wafer-scale, flexible pressure sensor matrix (PSM) for securer signature
collections by recording both the handwritten graphics and the signing habits (eg …

When dielectric materials are brought into contact and then separated, they develop static
electricity. For centuries, it has been assumed that such contact charging derives from the …

Bibliometric data set the scene by illustrating the growth of terahertz work and the present
interest in terahertz science and technology. After locating terahertz sources within the …

The efficient extraction of targets from complex surfaces is vital for technological applications
ranging from environmental pollutant monitoring to analysis of explosive traces and …

Zinc dialkyldithiophosphate additives are used to control wear and inhibit oxidation in almost
all engine oils as well as many other types of lubricant. They limit wear primarily by forming a …
