Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

Advanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

A Functional 2D Carbon Allotrope Combining Nanoporous Graphene and Biphenylene Segments

Advanced Materials, EarlyView.
The synthesis of a novel nanoporous graphene (NPG) is reported with biphenylene segments via thermal fusion of 12‐armchair porous graphene nanoribbons grown on gold surfaces. Characterization using STM, AFM, and DFT reveals low‐defect semiconducting behaviour and tunable band gaps.

Rotational Seismology and Engineering Applications: Proceedings for the First International Workshop Menlo Park, California, U.S.A.—September 18 to 19, 2007 [PDF]

, 2007
In our recent study of a seven-story reinforced concrete hotel in Van Nuys, California, which was damaged during Northridge 1994, earthquake, we showed that the prediction of where the localized damage may occur should be carried out by non-linear wave ...

Directional Flow of Confined Polaritons in CrSBr

Advanced Materials, EarlyView.
CrSBr, a layered magnetic semiconductor, naturally channels self‐hybridized excitonpolaritons into highly directional flow. Its intrinsic optical anisotropy, high refractive index, and strong lightmatter coupling enable long‐range guided modes along the a‐axis, with propagation lengths set by their excitonphoton admixture.

A Colloidal Quantum Dot Thermistor and Bolometer

Advanced Materials, EarlyView.
This work introduces colloidal quantum dot thermistors employing a potential barrier structure to tune the activation energy of transport and hence the temperature coefficient of resistance (TCR). Upon integration with plasmonic absorbers, the CQD‐based bolometer device enables room‐temperature wavelength‐selective photodetection across the mid‐ to ...

The fourth degree parabola (Bi-quadratic parabola) as a transition curve [PDF]

, 2012
Prijelazne krivulje su u konstrukciji modernih cesta i željezničkih pruga elementi jednako bitni kod poravnanja kao i zakrivljenja (kružnog). Kako bi se spriječila iznenadna promjena centrifugalne sile, prijelazna se krivulja mora primijeniti zbog ...
