High Thermoelectric Performance Achieved by Manipulating the Band Structure and Lattice Dislocations in n‐Type Ge/Pb/Br Codoped Polycrystalline SnSe

open access: yesCarbon Energy, EarlyView.
Pb/Ge/Br codoping in n‐type polycrystalline SnSe induces band convergence and high‐density dislocations, yielding a high power factor of 7.47 μW cm−1 K−2 and ultralow lattice thermal conductivity. Consequently, a peak ZT of 1.6 is achieved, overcoming the traditional performance limitations of n‐type SnSe.

Mixed Ion‐Electron Thermoelectric Generators With Ionogels Blended With MXene Continuously Harvesting Heat Under Both Steady and Fluctuated Temperature Gradients

open access: yesCarbon Energy, EarlyView.
A mixed ion‐electron thermoelectric generator (MTEG) based on MXene ionogels converts both steady and fluctuating temperature gradients into continuous electricity. The hybrid conduction arises from electron tunneling through MXene networks and ionic diffusion driven by the Soret effect, enabling stable voltage output and high thermopower for efficient

Highly Potent Fluorogenic Ligands for Triplex DNA: 5‐Substituted 2‐(Naphthalen‐2‐yl)‐4H‐Chromen‐4‐Ones

open access: yesChemistry – A European Journal, EarlyView.
5‐Substituted 2‐(naphthalen‐2‐yl)‐4H‐chromen‐4‐ones are reported as a novel class of highly potent and selective triplex DNA ligands. These ligands induce triplex formation at submicromolar concentrations and inhibit enzymatic activity via ligand‐mediated triplex formation.

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

open access: yesChemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...
