Frost resistance and micro mechanism of metakaolin and polypropylene fiber modified coastal cement soil

open access: yesJournal of Materials Research and Technology
In order to investigate the effects of metakaolin and polypropylene (PP) fiber on the macroscopic mechanical properties and microscopic mechanisms of cement soil subjected to freeze-thaw cycles, a series of unconfined compressive strength (UCS) and ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

open access: yesFEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Soil-Structure Interaction

open access: yes, 2023
The Editors are pleased to present this collection of 10 articles under the theme soil–structure interaction (SSI). The terminology SSI implies that an action from the surrounding ground would result in a reaction to the structure and vice versa, hence ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Soil utilization of solid waste: Small-strain dynamic properties and microscopic mechanism of phosphogypsum-modified coastal cement soil

open access: yesJournal of Materials Research and Technology
Phosphogypsum (PG), a solid waste from the wet process phosphoric acid industry, but the utilization rate is low at present. The effect of phosphogypsum and cement on small strain dynamic characteristics of coastal soft soil was studied by resonance ...

Impacts of Corn Straw Compost on Rice Growth and Soil Microflora under Saline-Alkali Stress

open access: yesAgronomy, 2023
Saline–alkali soil seriously inhibits crop growth and yields and threatens the sustainable development of agriculture. Corn straw compost can alleviate saline–alkali stress and improve crop growth and development.

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

open access: yesFEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.
