Laser‐Induced Graphene from Waste Almond Shells
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.

Summability of Fourier Series and its Derived Series by Matrix Means
ThisPaper introduces the concept of matrix operators and establishes two newtheorems on matrix summability of Fourier series and its derived series. theresults obtained in the paper further extend several known results on linearoperators.

Fourier Series Related to p-Trigonometric Functions
In this paper, we introduce the concept of generalized Fourier series, generated by the p-trigonometric functions, namely cosp and sinp, recently introduced related to the generalized complex numbers systems.

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics
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 ...

ON THE MATRIX SUMMATION OF FOURIER SERIES
One of the most important problems of applied mathematics is the series summation, in particular, linear matrix summation of the Fourier series. This problem appears, e.g., in finding the best approximation as well as in solving game problems of ...
