Molecular Photogearing for Controlling Rotary Motion at the Nanoscale. [PDF]

Chempluschem
Molecular gears capable of controlling and transmitting rotary motion at the nanoscale are indispensable for the construction of artificial molecular machines. In this concept, we discuss how molecular photogears featuring a propeller‐shaped motif attached to a light‐driven molecular motor offer new possibilities to perform these tasks with better ...

Efficient Harvesting of Irregular and Low‐Frequency Mechanical Energy via Hybridized Electromagnetic‐Triboelectric Systems

Small, EarlyView.
ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Non‐Rigid 3D Shape Correspondences: From Foundations to Open Challenges and Opportunities

Computer Graphics Forum, EarlyView.
Abstract Estimating correspondences between deformed shape instances is a long‐standing problem in computer graphics; numerous applications, from texture transfer to statistical modelling, rely on recovering an accurate correspondence map. Many methods have thus been proposed to tackle this challenging problem from varying perspectives, depending on ...

Working at Boimondau: A Community Experience

Sociology Lens, Volume 38, Issue 1, Page 66-74, March 2025.
Abstract In the 1940s and 1950s, France witnessed the emergence of labor communities whose ambition was to escape capitalism and abolish wage labor. This article focuses on Boimondau, the best‐known community at the time. In terms of work, the central activity in the life of the community, two main tensions lastingly structured the collective and ...

A Nanoparticle‐Integrated Complete Manufacturing Pipeline of Chemically Engineered Exosomes

Advanced Science, Volume 13, Issue 32, 9 June 2026.
We report a novel manufacture technology of chemically engineered exosomes. The four steps of manufacturing, i.e., biogenesis, loading, isolation, and storage, are integrated by the use of a nanoparticle. The manufacture technology incorporates three innovative components, i.e., a new nano‐bio effect, a new composite nanoparticle, and a new isolation ...

An autonomous and economical benthic incubation chamber for measuring dissolved oxygen fluxes in shallow, low‐flow environments

Limnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract Benthic incubation chambers enclose a known volume of water overlying a known area to measure water chemistry changes and are typically used to quantify the metabolic activity of benthic organisms or communities. Here we present an economical benthic incubation chamber for shallow, low‐flow environments, built using off‐the‐shelf components ...
