This article charts the importance of Berlin in the constellation of Bowie’s success and probes what stardom means in the context of Berlin. It links what Berlin meant to Bowie with what Bowie’s connection to the city has meant to Berlin in its establishing itself as the ‘poor but sexy’ clubbing capital of Europe. In order to get at the stylistic implications of this form of stardom, I bring together Bowie’s Berlin experiences with those of two countercultural personalities the city brought him together with, who are black stars in their own right: Christiane Felscherinow and Hedi Slimane. In ascertaining that Felscherinow and Slimane share with Bowie a dark aesthetic, which is also a politics and ethics of time and space, I probe the German Romantic lineage of the concepts of constellation and elective affinity and their critical potential via the writings of Berlin-born Walter Benjamin to show that this aesthetic is characteristic of the kind of stardom that the city of Berlin is struggling to maintain in the face of gentrifying pressures. Its appeal, I conclude, lies in the potential it offers for a lifestyle counter to the hegemonic, heteronormative, nuclear-family one of bourgeois modernity.

The wearable smart detection of body biomolecules and biomarkers is being of significance in the practical fields. Hydrogen peroxide (H 2 O 2 ) is a product of some enzyme-catalyzed biomolecular reactions. The detection of H 2 O 2 could reflect the concentration information of the enzyme reaction biomolecule substrate such as glucose. A high-performance berlin green (BG) carbon ink for monitoring H 2 O 2 was prepared in this work. And we have successfully developed the wearable smartsensors for detecting H 2 O 2 and glucose based on one-step fabricated BG arrays by screen-printing technology. Comparing with other detection methods, these sensors are wearable, movable, flexible and biocompatible for monitoring biomolecules. As a result, the sensors exhibited good sensitivity, specificity, stability and reproductivity towards H 2 O 2 and glucose. Additionally, there also received stable response after near one hundred times stretching and thousands of bending. Moreover, the wearable sensors could be easily remotely controlled by a smart phone, when integrated with wireless into the device. In prospective studies, the one-step fabricated wearable smartsensors is of great significance in developing a straightforward, highly-efficient and low-cost method for actual detection of biomolecules reflecting body health status , and would potentially be applied in the artificial intelligence (AI) fields.

I n this study, we report that Berlin Green (FeFe-BG) framework exhibits superior performance in the catalytic coupling of carbon disulfide (CS 2 ) and propylene oxide (PO) to generate a random copolymer containing thioether, propylene monothiocarbonate and ether units. Oxygen and sulfur atom exchange was detected in polymeric and cyclic thiocarbonate byproducts and utilized to modulate the copolymerization of CS 2 and propylene oxide. The coupling of PO and CS 2 was selective for copolymer formation under various reaction conditions. 1 H and 13 C NMR spectroscopy determined two distinct polymer linkages and two cyclic byproducts. Copolymer number average molecular weights ranged from 6.4 kg/mol to 10.5 kg/mol, with a comparatively low polydispersity of 1.3–1.7. The CS 2 /PO molar feed ratio had a significant impact on the O/S exchange process; the ratio of cyclic thiocarbonate byproducts could be efficiently regulated by tuning the CS 2 molar feed ratio.

Graphical An aqueous Zn-based battery with a Berlin green cathode, a K/Zn hybrid electrolyte, and a zinc metal anode are developed. Owing to the rapid insertion and transportation of K ions in the cathode materials and the good compatibility of electrolytes to the metal anode, the hybrid battery delivers improved rate capability and cycle performance. : Aqueous rechargeable zinc-based batteries with the advantages of sustainability, safety, and low cost, are suitable for large-scale electrochemical energy storage applications. In this work, aqueous zinc-based batteries with low defect Berlin green (FeHCF) cathode, a hybrid zinc triflate and potassium triflate electrolyte, and zinc anodes are developed. In the hybrid electrolyte, the K + ions with the weak solvation effect and small electrostatic interaction are the dominant intercalation species in the FeHCF, resulting in the fast charge transfer process and rapid diffusion kinetics. The Zn 2+ ions stay at the surface rather than penetrate into the bulk phase. Thus, the hybrid batteries deliver a high specific capacity of 169.2 mAh g −1 at 100 mA g −1 , excellent rate performance with 45.7 mAh g −1 at 6 A g −1 , and good long-term cyclability with a capacity retention of 57 % over 1000 cycles at 1 A g −1 . The results suggest using aqueous K/Zn hybrid electrolytes can improve the electrochemical performance of FeHCF.

An inorganic anticorrosive coating, merging wollastonite into Chemically Bonded Phosphate Ceramic (CBPC) binders, was prepared to protect rebar from corrosion. In order to evaluate the corrosion resistance behavior of Wollastonite-based Chemically Bonded Phosphate Ceramic (WoCBPC) coatings, the electrochemical measurements were applied. The experiment results showed that the value of corrosion potential (E corr ) and polarization resistance (R p ) is the largest and the value of corrosion current density (I corr ) is the smallest among all WoCBPC coatings, when the content of wollastonite reaches 20% of the ceramic filler (WoCBPC20). Moreover, the resistance of WoCBPC20 coating (R c ) value was much higher than that of other WoCBPC coatings, which means the best anticorrosion properties. The structure formation of WoCBPC coatings was identified by using XRD as well as SEM/EDS techniques. The intensity of berlinite phase reaches the maximum with the introduction of wollastonite in WoCBPC20 coatings. Meanwhile, the fibrous wollastonite particles with high modulus can inhibit the spread of cracks in CBPC matrix. Therefore, the WoCBPC coatings show a barrier effect to prevent aggressive substances from contacting the rebar effectively.

Rechargeable Fe-ion batteries with overwhelming cost/environmental benign superiorities hold great promise in large-scale charge-storage applications. However, there is still a lack of competitive cathodes with prominent capacity and long-term cyclability. To overcome these constraints, a unique Fe 2+ /NH 4 + co-insertion strategy is proposed, enabling both doubled reversible capacity and cyclic life of Berlin green (FeHCF) cathodes. The Fe 2+ insertion proves to induce FeHCF lattice contractions, alter ligand environment/activation energies of low-spin Fe III, and hence boost the redox conversion depth, while NH 4 + co-insertions help to elevate the cathode capacities by utilizing Fe 2+ -unoccupied reaction sites. Besides, they generate hydrogen bonds between inserted NH 4 + ions and N atoms in FeHCF, capable of vastly strengthening the cathode's cyclic durability. Cathodes in such collaborative dual-cation electrolytes exhibit a remarkable capacity of 162 mAh g −1 (4 A g −1 ) and far prolonged operation lifespan (over 1000 cycles) when compared to single-cation cases. The assembled full cells demonstrate impressive energy densities up to 70.4 Wh kg −1 , and far superior capacity retention of 88% after all the cycling. This work may offer a simple/feasible, and effective route to render high-capacity and long-lasting cathodes for future/practical Fe-ion battery systems.
