Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

A computational analysis of a family of Szász type operators based on Tricomi functions
Journal of Inequalities and ApplicationsThis paper introduces a novel family of integral operators incorporating Tricomi functions. We derive explicit estimates for test functions and central moments, alongside establishing uniform convergence via the Korovkin theorem and approximation order ...

Towards the best constant in front of the Ditzian-Totik modulus of smoothness
Journal of Inequalities and Applications, 2016 We give accurate estimates for the constants K ( A ( I ) , n , x ) = sup f ∈ A ( I ) | L n f ( x ) − f ( x ) | ω σ 2 ( f ; 1 / n ) , x ∈ I , n = 1 , 2 , … , $$ K\bigl(\mathcal{A}(I), n, x\bigr)=\sup_{f\in\mathcal{A}(I)}\frac{|L_{n} f(x)-f(x)|}{\omega_ ...

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics
Advanced Functional Materials, EarlyView.We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Modified Stancu operators based on inverse Polya Eggenberger distribution
Journal of Inequalities and Applications, 2017 In this paper, we construct a sequence of modified Stancu-Baskakov operators for a real valued function bounded on [ 0 , ∞ ) $[0,\infty)$ , based on a function τ ( x ) $\tau(x)$ .

An Edible Chitosan‐Based Acoustic Sensor for Sound‐Responsive Actuation in Edible Robots
Advanced Functional Materials, EarlyView.This study introduces an edible acoustic sensor for robotic food and edible robotics. Built from a chitosan piezoelectric film between gold electrodes, the sensor enables acoustic communication through ON/OFF keying. Integrated into an edible robot with pneumatically actuated arms and neck, it responds to high‐frequency tones.
