Layered NiCo–OH nanosheets are converted into spinel-structured NiCo 2 O 4 via low-temperature calcination, enabling precise tuning of surface acid sites. Systematic C 1 –C 6 Alcohol Screening: The ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

When substances combine with oxygen the process is called oxidation and the compounds made are called oxides. The sparks in fireworks are made by burning different metals. The burning metals are ...

New findings reveal that organosulfate groups, not carboxyls, control graphene oxide's surface charge in water, challenging long-standing models and reshaping its chemical profile. (Nanowerk Spotlight ...

Researchers discover that embedding iridium atoms inside catalyst crystals instead of on the surface dramatically improves durability for green hydrogen production. (Nanowerk News) Producing green ...

A Northwestern University-led team recently found the answer to a mysterious question that has puzzled the materials science community for years—and it came in the form of some surprisingly basic ...
