Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

open access: yesThe Chemical Record, EarlyView.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

open access: yesVIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

Thermal Conductive Network Construction and Enhanced Thermal Conductivity in Mica Tape Composites for Large Generators by Pre‐Placed h‐BN@PDA‐Modified Mica Paper

open access: yesHigh Voltage, EarlyView.
ABSTRACT The lower thermal conductivity (TC) of mica tape hinders the evolution of large generators towards higher voltage and capacity. To enhance the TC of the mica tape, with the help of the three‐dimensional (3D) multi‐layer framework of the mica paper, a 3D polydopamine‐coated boron nitride (h‐BN@PDA) TC network was constructed by pre‐placing h‐BN@

Insights into the 3D structure and behaviour of Icelandic crystal mushes from gabbroic nodules

open access: yes
Crystal mushes – porous yet cohesive frameworks of crystals interspersed with interstitial melts – form the plumbing systems of most active volcanoes. In Iceland, magmatic plumbing systems are inferred to be constructed from vertically stacked mushy magma reservoirs separated by subsolidus rock. Gabbroic nodules from Gígöldur in central Iceland provide

Time‐resolved 3D imaging opportunities with XMPI at ForMAX

open access: yesJournal of Synchrotron Radiation, EarlyView.
The first implementation of X‐ray multi‐projection imaging (XMPI) at the ForMAX beamline (MAX IV) enables the acquisition of multiple projections simultaneously without requiring sample rotation. This approach facilitates volumetric studies of fast dynamics at frame rates of 12.5 kHz with micrometre resolution, with the potential of even higher speeds,

From Tobacco to Ultraprocessed Food: How Industry Engineering Fuels the Epidemic of Preventable Disease

open access: yesThe Milbank Quarterly, EarlyView.
Policy Points Ultraprocessed foods (UPFs) are engineered to heighten reward and accelerate delivery of reinforcing ingredients, driving compulsive consumption and disrupting appetite regulation. This is a growing challenge for health policy. UPFs share key engineering strategies adopted from the tobacco industry, such as dose optimization and hedonic ...

Cyotoxicity of Etidronate as an Endodontic Chelator Against Periodontal Ligament Fibroblast

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT Etidronic acid (HEBP) causes fewer alterations in dentine and can be used mixed with sodium hypochlorite during root canal preparation. This study investigated the cytotoxicity effects of the HEDP and EDTA on human periodontal ligament fibroblast cells. Primary culture was established from human periodontal ligament tissue of one donor and was

Analysis of Solubility, pH, Antimicrobial Action and Cytotoxicity of Calcium Hydroxide Paste Associated With Ambroxol Hydrochloride

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the association of ambroxol hydrochloride with calcium hydroxide paste as intracanal medication to enhance antimicrobial action on biofilm without affecting pH, solubility and cytotoxicity. Calcium hydroxide (CH) paste and formulations with different ambroxol concentrations were placed into artificial teeth conditioned in ...
