Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

open access: yesAdvanced Science, Volume 13, Issue 15, 13 March 2026.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

Combining Electrochemical Reduction with Biosynthesis for Directed Conversion of CO2 into a Library of C3 Chemicals

open access: yesAdvanced Science, Volume 13, Issue 17, 23 March 2026.
In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.

Adaptive Laboratory Evolution of Cupriavidus necator to Improve Energy Demand in Bioelectrochemical Cultivations

open access: yesChemElectroChem, Volume 13, Issue 5, March 2026.
This study highlights biological improvement through adaptive laboratory evolution of Cupriavidus necator H16 ΔPHB. Adapted strains tolerated up to 400 mM Na2SO4 showing better growth under salt stress. This enhanced robustness reduced cultivation energy demand in bioelectrochemical systems by ~ 11%, enabling more sustainable bioelectrochemical ...

Functionalisation of polyhydroxybutyrate for diagnostic uses

open access: yesNew Biotechnology
Polyhydroxybutyrate (PHB) is a biodegradable and biocompatible biopolyester, naturally produced and self-assembled as spherical inclusions inside bacteria. These PHB particles contain a hydrophobic PHB core covalently coated with PHB synthase (PhaC), which serves as an anchoring linker for foreign proteins of interest.
