The Inka Khipu and Yupana: A Reply to Zen Vasconcellos and Rojas Gamarra (2026)

Astronomische Nachrichten, EarlyView.
ABSTRACT A new analysis by Zen Vasconcellos and Rojas Gamarra offers a novel interpretation of the Inka devices used for calculating (yupana) and recording (khipu) numbers. They claim the Inka devices represented numbers neither positionally, with place value, as most researchers have assumed, nor additively, without place value, a possibility uniquely

Elucidating the Interplay Between Structure and Electrochemical Behavior in Lignin‐Based Polymer Electrolytes for Potassium Batteries

Battery Energy, Volume 4, Issue 2, March 2025.
Three biobased membranes are synthesized by crosslinking oxidized Kraft lignin with poly(ethylene glycol) diglycidyl ether of increasing molecular weights. After incorporation of solvated potassium salts, potassium batteries including these biobased gel polymer electrolytes are able to deliver a maximum specific capacity at 0.05 A g−1 as high as 130 ...

Infinite Functional Versatility, Formidable Limits: Evaluating Gallium‐Based Liquid Metals in Rechargeable Batteries

Carbon Energy, EarlyView.
Beyond the hype surrounding the self‐healing properties of gallium‐based liquid metals (Ga‐LMs), this perspective critically examines their functional roles in metal‐ion batteries, highlighting both their underlying merits and the often‐overlooked challenges, including non‐representative design and testing configurations, performance overestimations ...

Applications of Biomaterials in Separators for Secondary Batteries

Carbon Energy, EarlyView.
In this review, biomaterial‐based separators are reviewed as sustainable alternatives to conventional polyolefin‐based separators. For 12 different natural polymers, spanning from Protista, Plantae, and Animalia, viable strategies for synthesizing biomass‐based separators are described.

Iso‐Tellurazole N‐Oxides Assemble Adaptively Folded Macrocyclic Dodecamers

Chemistry – A European Journal, EarlyView.
Te…O Chalcogen bonding links twelve molecules into a ring that wraps itself around molecular guests. ABSTRACT Self‐assembled macrocyclic dodecamers were found in the crystals of new pseudo‐polymorphs of iso‐tellurazole N‐oxides. These structures are formed by molecules connected by NTe…O chalcogen bonds and are folded in a pattern that defines 89–153 ...
