Radon Equilibrium Factor and the Assessment of the Annual Effective Dose at Underground Workplaces

Atmosphere
The equilibrium factor F is one of the parameters that should be considered when assessing the effective dose based on radon activity concentration. Since the equilibrium factor in various environments ranges theoretically from a value close to 0 to 1 ...

Comparison of the accident process, radioactivity release and ground contamination between Chernobyl and Fukushima-1

Journal of Radiation Research, 2015
In this report, we have reviewed the basic features of the accident processes and radioactivity releases that occurred in the Chernobyl accident (1986) and in the Fukushima-1 accident (2011).

Solvent‐Induced Octahedral Self‐Assembly of Prussian Blue and Its Applications in Sodium‐Ion Capacitors

Advanced Functional Materials, EarlyView.
This study investigates the stepwise assembly process of octahedral Prussian Blue (PB) particles in glycerol. Initially, smaller cubic PB nanoparticles form and interact in the solvent. Over time, these particles undergo dissolution and reassembly, leading to the formation of well‐defined octahedral structures with minimized surface energy.

Nanostructured Hydrogen‐Selective Palladium “Plug” Membranes Capable of Withstanding High Temperatures

Advanced Functional Materials, EarlyView.
A nanostructured palladium membrane is developed for high‐temperature hydrogen separation, comprising isolated, thermally‐stable palladium plugs embedded within nanopores of a porous support. The membrane withstands high temperatures (1000 K for 100 h) without structural failure, demonstrating exceptional robustness over conventional metal membranes ...

Cold Quad‐Modal Nanocomplex for Precise and Quantitative In Vivo Stem Cell Tracking

Advanced Functional Materials, EarlyView.
Multimodal albumin–bismuth sulfide–superparamagnetic iron oxide (ABS) nanocomplexes are developed for stem cell tracking across four different imaging modalities: MRI, MPI, MSOT, and CT. Combining its flexibility with high sensitivity, this quad‐modal imaging agent enables a robust quantification of ABS‐labeled stem cells in vivo.

Metallofullerenol Sc3N@C80(OH)18: A New Generation Radioprotector Protecting Human Erythrocytes Against Multiple Biochemical Damage Modes Upon Gamma Irradiation, Identifying It as a Scavenger of Short‐ and Long‐Lived Radicals

Advanced Healthcare Materials, EarlyView.
Metallofullerenol Sc3N@C80(OH)18 demonstrates strong radioprotective properties as a scavenger of both short‐ and long‐lived radicals. The study reveals protection of human erythrocytes from γ‐radiation–induced biochemical damage via post‐irradiation removal of primary and secondary reactive oxidants, supported by pulse radiolysis kinetics.

Evaluating Cytocompatibility of Corynebacterium glutamicum‐poly Vinyl Alcohol Living Biomaterials for Ocular Use

Advanced Healthcare Materials, EarlyView.
In ophthalmology, living biomaterials such as living contact lenses appear promising for sustained drug delivery or biosensing. The cytocompatibility of Cg‐PVA hydrogels, developed as a model living contact lens, is investigated with the ocular surface, showing their potential translation to the clinic.

Digitonin‐Loaded Nanoscale Metal–Organic Framework for Mitochondria‐Targeted Radiotherapy‐Radiodynamic Therapy and Disulfidptosis

Advanced Materials, EarlyView.
A mitochondria‐targeted cationic nanoscale metal organic framework shows strong radiotherapy‐radiodynamic therapy effects and selectively releases digitonin in acidic tumor microenvironments to induce disulfidptosis of cancer cells and downregulate immune checkpoints in cancer and T cells, thereby eliciting strong antitumor immunity to effectively ...

Dendrimers Improve Apolipoprotein Nanoparticle mRNA Delivery to Immune Cells

Advanced Materials, EarlyView.
Apolipoprotein nanoparticle (aNP) platform technology efficiently delivers RNA to immune cells following systemic administration. Here, it is demonstrated that incorporating polyvalent ionizable cationic dendrimers in aNPs enables robust mRNA complexation and functional delivery.
