Programmable Guest‐Induced 5‐Phase‐Transition Topological Reconstructions of Cobalt Formate Metal–Organic Frameworks

open access: yesAdvanced Science, EarlyView.
A reversible five‐phase topological cycle is achieved in a minimalist cobalt formate metal–organic framework. The amorphous phase functions as a programmable reactive hub, selectively reconstructing into four distinct crystalline architectures through cationic templates, humidity, or CO2.

Perchlorate exposure and thyroid function in ammonium perchlorate workers in Yicheng, China. [PDF]

open access: yesInt J Environ Res Public Health, 2014
The impact of low level dust on the thyroid function of workers chronically exposed to ammonium perchlorate (AP) is uncertain and controversial. The aim of this study was to examine whether workers in China with long-term (>3 years) occupational ...

Quercetin‐zinc coordination polymer coated CaCO3 nanoparticles potentiate radiotherapy through reprogramming tumor immunosuppression

open access: yesBMEMat, EarlyView.
Synthesis of QZCaCO3‐PEG to synergistically enhance the immunogenicity of radiotherapy through concurrent Zn2+‐induced cancer cell pyroptosis and Que‐mediated hypoxia amelioration through sequentially suppressing TGF‐β secretion and ECM deposition. Abstract Radiotherapy has demonstrated broad applications in treating solid tumors, but the hostile tumor

One-pot hydrothermal synthesis of reduced graphene oxide/zinc ferrite nanohybrids and its catalytic activity on the thermal decomposition of ammonium perchlorate

open access: yesJournal of Saudi Chemical Society, 2019
Reduced graphene oxide/Zinc ferrite (rGO/ZnFe2O4) nanohybrids are successfully decorated on the surface of the rGO sheets through a simple, one-step hydrothermal method. ZnFe2O4 nanoparticles (NPs) are homogeneously anchored on the rGO sheets.

Tribochemical Surface Modification of Silicon

open access: yesChemistry – A European Journal, EarlyView.
Mechanical scribing activates silicon surfaces by generating reactive sites that spontaneously graft alcohol‐, thiol‐, and alkyne‐terminated molecules under ambient conditions. Within 10 s, high‐coverage, electroactive organic layers form without light, heat, or applied voltage, offering a rapid tribochemical route to functional silicon interfaces for ...
