An ATP7A‐Mediated Endogenous Regulation Bio‐Clay Enzyme Enables Self‐Amplified Copper Accumulation for Immunogenic Pyrop

Advanced Science, EarlyView.
A self‐amplifying bio‐clay nanozyme (Bio‐Clayzyme) disrupts tumor metabolic homeostasis through endogenous copper transporter ATPase (ATP7A) downregulation, enhancing cascade catalysis and triggering immunogenic pyroptosis for effective tumor immunotherapy.

Engineering Polar Nanoregions in COFs via Controlled Symmetry Breaking Toward Piezocatalysis

Angewandte Chemie, EarlyView.
Polar nanoregions (PNRs) are engineered within covalent organic frameworks via asymmetric grafting of highly polar polyfluoroalkyl chains, which enables controlled symmetry breaking. These randomly oriented artificial PNRs dynamically respond to mechanical stimuli and impart relaxation behavior to the COFs (TFB‐TAPT‐FA).

Platinum-group minerals in the Jinchuan complex, China

, 2005
Platinum-group elements (PGE) and minerals (PGM), most commonly froodite (PdBi2), michenerite (PdTeBi), padrnaite (PdBiSe), sperrylite (PtAsz) and irarsite (IrAsS), have been analysed from the Jinchuan Ni-Cu-PGE sulphide deposit in the south western ...

Chemical Compositions and Paragenesis of the Platinum-group Element Minerals in the Jinchuan Sulfide Deposit, Gansu Province, China [PDF]

, 1992
A variety of platinum group minerals (PGM) occurs in the Jinchuan deposit, China. Four different PGM assemblages have been distinguished as follows: The first group, mainly sperrylite, occurs within altered olivines.

Platinum-Group Mineral Occurrences and Platinum-Group Elemental Geochemistry of the Xiadong Alaskan-Type Complex in the Southern Central Asian Orogenic Belt

, 2018
Alaskan-type complexes commonly contain primary platinum-group element (PGE) alloys and lack base-metal sulfides in their dunite and chromite-bearing rocks. They could therefore host PGE deposits with rare sulfide mineralization.

Atomically Dispersed Fe‐Modified SnS for Sn‐Centered Peroxymonosulfate Activation Toward Acetaminophen Degradation

Advanced Science, EarlyView.
Atomically dispersed Fe regulates the local electronic environment and surface properties of SnS, while PMS preferentially coordinates to Sn through Sn–O interaction. Fe incorporation further enhances the Sn–OPMS interfacial interaction, facilitating Sn‐centered PMS activation and the generation of SO4•−/•OH for APAP degradation, thereby clarifying the

Platinum group minerals and associated phases at Aguablanca Ni-Cu-(PGE) deposit, SW Spain

, 1998
Aguablanca is a Ni-Cu-(PCE) sulphide mineralization associated to mafic facies of the Santa Olalla hercynian intrusion. The sulphides occur as disseminated ore, massive ore and brecciated ore related to gabbros, norites and minor piroxenites and ...

Self‐Assembled Pt(II) Complexes Boost Up Stem Cell Proliferation and Accelerate Metamorphosis in Living Organisms

Angewandte Chemie, EarlyView.
Pt1, an organometallic platinum‐based complex, act as a modulator of redox homeostasis in cnidarians, regulating cellular functions and life‐cycle dynamics. In Nematostella vectensis, it mitigates oxidative stress, strengthens detox systems and accelerates development.
