What are Biopolymer-Based Hydrogel Electrolytes?

Hydrogel electrolytes based on biopolymers have gathered increased attention due to their functionality, low cost, abundance, flexibility, and eco-friendliness. The biopolymers play a role in ion conduction, enabling high electrolytic conductivity, mechanical robustness, and thermal stability, in ad

X-Ray Photoelectron Spectroscopy of Lithium Salts in Batteries

In a paper recently published in the open-access journal ACS Energy Letters, researchers presented a comprehensive X-ray photoelectron spectroscopy (XPS) study of three Li salts, namely lithium hexafluorophosphate (LiPF6), lithium bis-(trifluoromethanesulfonyl)imide (LiTFSI), and lithiumbis(fluorosulfonyl)imide (LiFSI).

Scientists Present Two Time-Efficient Surrogate Models for Laser Powder Bed Fusion

In a paper recently published in the journal Additive Manufacturing, researchers proposed two surrogate models efficient for reproducing the nonlinearity of the heat equation with respect to laser powder bed fusion (LPBF), while comparing its performance in online execution time and accuracy.

Using Branched Polyethylenimine as Semiconductor Junction Contacts

In a paper recently published in the open-access journal ACS Applied Energy Materials, researchers studied the usage of polymeric films of polyethylenimine (PEI) for interfacial enhancement of electron-selective contacts. The modification of PEI increased the performance of conventional highly efficient heterojunction solar cells.

Using Decellularized Extracellular Matrix as a Biomaterial

In a paper recently published in the journal Biomaterials, researchers examined the challenges, synthesis techniques, and advances made in the development of decellularized extracellular matrix (dECM)-based biomaterials to imitate specific physical and biological characteristics of native tissue.

Improving the Efficiency of Quasi-2D Perovskite Solar Cells

In a paper recently published in the journal ACS Energy Letters, researchers comprehensively studied phase manipulation efficiency in BA2MA4Pb5 I16 (n = 5) quasi-two-dimensional (quasi-2D) perovskites. They used the dimethyl sulfoxide (DMSO) solvent to manipulate the crystalline growth process in the quasi-2D perovskite film.
