Managed honey bee colony losses in Canada, China, Europe, Israel and Turkey, for the winters of 2008-9 and 1009-10 [PDF]

, 2012
In 2008 the COLOSS network was formed by honey bee experts from Europe and the USA. The primary objectives set by this scientific network were to explain and to prevent large scale losses of honey bee (Apis mellifera) colonies.

A Comprehensive Review of Additive Manufacturing for Space Applications: Materials, Advances, Challenges, and Future Directions

Advanced Engineering Materials, EarlyView.
Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

Micromechanical Insights into Sinter‐Based Additively Manufactured NiTi with Nb as a Sintering Aid

Advanced Engineering Materials, EarlyView.
This study investigates the microstructural and micromechanical behavior of NiTiNb made through filament‐based materials extrusion via chemically correlated nanoindentation. B19' remnants from the original powder lead to Nb gradients within NiTiNb grains due to the short sintering times required in liquid‐phase sintering.

Deformation Behavior of Optical Ceramic Nanomultilayers: The Role of Aperiodicity

Advanced Engineering Materials, EarlyView.
Ceramic nanomultilayers demonstrate optical and mechanical behavior tunability through aperiodicity. Within the studied systems, optically optimized coatings exhibit an average ultraviolet, visible, and near‐infrared spectral transmittance above 90%.

The influence of partial substitutes of protein feed of bees on the production of drone larvae homogenate

Науковий вісник Львівського національного університету ветеринарної медицини та біотехнологій імені С.З. Гжицького. Серія: Сільськогосподарські науки, 2020
The biological value of the bee drone brood homogenate is showed. In recent times, the bee drone brood homogenate has become widely used among the population. In particular, the nutritional value the drone brood homogenate is determined by a high content

LiVO3/LiZnVO4 Nanocomposite: High Performance Electrocatalyst for Ambient Nitrogen Reduction to Ammonia

Advanced Engineering Materials, EarlyView.
Lithium‐mediated electrocatalysis enables sustainable N2 fixation but hindered by parasitic Li deposition. An oxide‐oxide nanocomposite (LiVO3/LiZnVO4) structurally integrates lithium into active sites, suppressing plating and enhancing N2 activation and HER supression.

Direct Recycling of Cold Work Tool Steel Swarf into New Cutting Disks via Field‐Assisted Sintering

Advanced Engineering Materials, EarlyView.
Through a sintering method known as field‐assisted sintering technology/spark plasma sintering, cold work tool steel swarf can be directly recycled into new cutting disks. This method is capable of densifying the unconventional powder morphology of swarf, and it can also seal grinding contaminants, such as Al2O3, into the steel matrix.
