Make‐Use‐Remake: Toward Indefinite Low‐Temperature Material Loops
We introduce a regenerable materials platform built from microparticles bound by a temperature‐responsive polymer shell, enabling strong, processable structures from diverse feedstocks. The material is shaped at low temperatures (80°C) using common manufacturing methods and reprocessed repeatedly in the presence of water, demonstrating stable ...

Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

تلويث البيئة البحرية من منظور دولي Polluting Marine Environment: An International Perspective [PDF]
ظاهرة التلوث البيئي أو التلوث البحري، ليست حديثة العهد, وإن كان الاهتمام بها حديثا فالتلوث موجود على الأرض, منذ وجدت الحياة ووجد الكائن البشري، لكن الطبيعة كانت قادرة بقواها الذاتية, على امتصاص التلوث وتنقية ذاتها بذاتها، ما دامت كمية التلوث الناتجة ...

Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Vacuum‐assisted capillary infiltration delivers perovskite precursors deep into gold nanohole plasmonic hotspots, enabling uniform in situ crystallization of bulk‐like CsPbBr3 within confined cavities. Verified by peel‐off and structural analyses, the hybrid platform shows simulated |E/E₀| ≈2.80 at 800 nm and ∼40‐fold two‐photon absorption‐enhanced ...

In this work, we introduce ancillary‐ligand‐mediated growth control of ultrathin CsPbI3 PeNPLs to achieve highly uniform thickness and reduced agglomeration. Strong ancillary‐ligand coordination to the perovskite surface regulates nucleation and improves surface passivation, enabling color‐pure emission and preferentially oriented superlattices.

Why did only one genus of insects, Halobates, take to the high seas?
Oceans cover more than 70% of the Earth’s surface and house a dizzying array of organisms. Mammals, birds, and all manner of fish can be commonly sighted at sea, but insects, the world’s most common animals, seem to be completely absent.

Oceans. The impact of global change on the sea
A phenomenon of exceptional importance such as global change and its multiple effects has been discussed in several Mètode monographs. In recent years, public concern about what we already perceive to be the greatest threat to humanity has not stopped growing; at the same time, the United Nations have proclaimed the period 2021-2030 as the Decade of ...
