Pembuatan Karbon Aktif dari Ampas Sagu Menggunakan Aktivator ZnCl2

open access: yesJurnal Fisika Flux, 2021
Activated carbon is a carbon with an amorphous structure arranged in a parallel hexagonal ring. In this research, activated carbon has been synthesized from sago waste.

Development of Formaldehyde Adsorption using Modified Activated Carbon - A Review [PDF]

open access: yes, 2012
Gas storage is a technology developed with an adsorptive storage method, in which gases are stored as adsorbed components on the certain adsorbent. Formaldehyde is one of the major indoor gaseous pollutants.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Exothermicity during the pyrolysis of large wood particles

open access: yesFuel Processing Technology
In addition to conventional pyrolysis processes, pyrolytic decomposition also plays a major role in gasification and combustion. In all of these thermochemical conversions, biomass particles of varying sizes are used.

Preparation of activated carbon from biomass and its application in gas adsorption [PDF]

open access: yes, 2017
Biomass is an abundantly available and sustainable resource, which is widely utilized as precursor for producing activated carbons. In this thesis, hemp hurd and retted hemp hurd, the by-products of hemp fibre industry, were used as precursors for the ...

Activated Carbon from Biomass Sustainable Sources

open access: yes, 2021
Biomass wastes are abundant around us. They are renewable and inexpensive. Product manufacturing from renewable resources has caught increasing interest recently. Activated carbon preparation from biomass resources, including various trees, leaves, plant

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Performance evaluation of a novel two-stage waste wood gasifier: Influence of steam-to-biomass ratio and in-situ steam generation on tar formation

open access: yesFuel Processing Technology
The shift from high-quality woodchips to low-quality feedstocks increasingly shapes biomass gasification. Small- to medium-scale plants face challenges from heterogeneous feedstock and tar formation, with a research gap in producing energetically useable
