Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces
Advanced Functional Materials, EarlyView.Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.

Some new integral inequalities for (s, m)-convex and (α, m)-convex functions
Қарағанды университетінің хабаршысы. Математика сериясы, 2019 The paper considers several new integral inequalities for functions the second derivatives of which, with respect to the absolute value, are ( s,m )-convex and ( α,m )-convex functions.

Advanced Functional Materials, EarlyView.Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Positivity of sums and integrals for n-convex functions via the Fink identity
TURKISH JOURNAL OF MATHEMATICS, 2019 We consider the positivity of the sum $\sum_{; ; ; ; i=1}; ; ; ; ^n p_iF(x_i)$ where F is a convex function of higher order as well as analogous results involving the integral $\int_a^bp(x)F(g(x))dx$. We use a representation of the function $F$ via the Fink identity and the Green function that leads us to identities from which we obtain conditions for ...

A Non‐Reciprocal Architected Porous Medium
Advanced Functional Materials, EarlyView.ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

Generalized Steffensen’s inequality by Montgomery identity
Journal of Inequalities and Applications, 2019 By using generalized Montgomery identity and Green functions we proved several identities which assist in developing connections with Steffensen’s inequality.

Depth functions based on a number of observations of a random vector [PDF]
We present two statistical depth functions given in terms of the random variable defined as the minimum number of observations of a random vector that are needed to include a fixed given point in their convex hull.

Advanced Healthcare Materials, EarlyView.Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...
