A novel n-type semiconducting biomaterial
Scientific Reports, 2022 There has been no research conducted thus far on the semiconducting behaviour of biomaterials. In this study, we present an n-type semiconducting biomaterial composed of amorphous kenaf cellulose fibre (AKCF) paper with a voltage-controlled N-type ...

Downscaling of fracture energy during brittle creep experiments [PDF]
, 2011 We present mode 1 brittle creep fracture experiments along fracture surfaces that contain strength heterogeneities. Our observations provide a link between smooth macroscopic time-dependent failure and intermittent microscopic stress-dependent processes.

Development of Highly Sensitive Strain Sensor Using Area-Arrayed Graphene Nanoribbons
Nanomaterials, 2021 In this study, a basic design of area-arrayed graphene nanoribbon (GNR) strain sensors was proposed to realize the next generation of strain sensors. To fabricate the area-arrayed GNRs, a top-down approach was employed, in which GNRs were cut out from a ...

PyFrac: A planar 3D hydraulic fracture simulator
, 2020 Fluid driven fractures propagate in the upper earth crust either naturally or in response to engineered fluid injections. The quantitative prediction of their evolution is critical in order to better understand their dynamics as well as to optimize their

Presidential Succession and Disability [PDF]
, 1956 Background: Recent research in a large cohort of women showed that coffee consumption is not associated with increased risk of fracture. Whether this is the case also among men is less clear. Methods: In the Cohort of Swedish Men (COSM) study, 42,978 men

Impact and indenting damage of CVD-produced ZnS and ZnSe ceramics
Materials Research Express, 2020 Time series of acoustic emission pulses were excited in ductile ZnS and ZnSe ceramics either by a falling weight or by indenting the Vickers pyramid. Energy distributions in emitted acoustical emission pulses were found to be random (Poisson-like) in the

Reverse Ballistic Impact Studies of Thin Plate Perforation
Engineering Transactions, 2014 Full-scale ballistic experiments using tungsten rods and rolled homogeneous armour (RHA) steel plates are expensive to perform. For this reason, a study has been performed into the possibility of using less expensive, more easily available metals in ...
