An introduction to Trends in Extreme Weather and Climate Events: Observations, Socioeconomic Impacts, Terrestrial Ecological Impacts, and Model Projections [PDF]

, 2000
Weather and climatic extremes can have serious and damaging effects on human society and infrastructure as well as on ecosystems and wildlife. Thus, they are usually the main focus of attention of the news media in reports on climate.

From Single Atoms to Nanoparticles: Pathways Toward Efficient and Durable Pt/TiO2 Photocatalysts

Advanced Functional Materials, EarlyView.
Platinum single atoms on TiO2 nanosheets evolve into clusters and nanoparticles under ethanol photoreforming and thermal treatments. By controlling deposition and post‐treatments, particle size and location on specific facets are modulated. The study reveals how stability pathways determine efficiency, guiding the design of more durable photocatalysts.

Climatic warming and freshwater environment. Climatic warming and lake plankton communities.

Japanese Journal of Limnology (Rikusuigaku Zasshi), 2000
地球温暖化の湖沼プランクトン群集に及ぼす影響について,これまでの報告を整理し,考察を加えた。温暖化が進むと湖の深水層の溶存酸素濃度が低下し,植物プランクトン群集ではラン藻が優占するようになる。この影響は湖の富栄養化に似ている。動物プランクトン群集では,高温耐性の低いアミやDaphniaが減ることになる。また,多くの動物プランクトン種で成熟サイズの低下が起きる。温暖化は暖水性の魚の分布域を広げ,逆に冷水性の魚の分布域を大きく狭める。この変化は動物プランクトンの種組成や分布を変えることになる。また,それ以外にも様々な生物問相互作用に影響を与えると考えられる。温暖化は生物多様性にも影響し,プランクトン群集の種多様性を低下させるとみられている。さらに ...

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

Advanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Scenarios and roots of climate change [PDF]

, 2012
There have been more and more words about climate change and global warming in the last few decades. But what do we really understand them? Is it logic that the climate change derived by human behaviour or is it an independent process of nature that ...

Scalable Polyelectrolyte Complex‐Based Sorbent With Hourly Sorption−Desorption Cycles for Multicyclic Atmospheric Water Harvesting in Arid Environments

Advanced Functional Materials, EarlyView.
A polyelectrolyte complex‐based sorbent is produced by scalable, environmentally benign aqueous phase inversion. Its porous, LiCl‐ and GO‐integrated architecture enables hourly adsorption−desorption cycles at low relative humidity (RH < 30%). A large‐scale prototype achieves multicyclic, solar‐driven atmospheric water harvesting of 1.37 L kg−1 day−1 ...

Climate change in the European Union [PDF]

It is now universally accepted that climate change is happening and that is caused by man’s behaviour. Global warming is accelerating and the average temperature is likely to rise up to 4 degrees by the end of this century if nothing is done.

Prenucleation Species Dictate Foreign Ion Incorporation in the Biomineral Precursor Amorphous Calcium Carbonate

Advanced Functional Materials, EarlyView.
ACC forms via aggregating prenucleation clusters that gatekeep its chemical composition. Ion identity steers the path: Ba and Sr substitute Ca in clusters, thereby inhibiting nucleation, with a dose‐dependent switch of Sr to induction. Mg partitions into Mg‐rich and Mg‐poor clusters; the latter form ACC, expelling Mg.
