Exploring the Potential of Zero‐Dimensional Carbon Nanomaterials in Photoluminescent, Electrochemiluminescent and Electrochemical Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
Zero‐dimensional carbon nanomaterials are presented as multifunctional platforms linking structure, property, and sensing performance. Surface engineering and heteroatom doping modulate electron‐transfer and luminescent behavior, enabling electrochemical, photoluminescent, and electrochemiluminescent detection. Fundamental design principles, analytical

Magnetically Actuated Drops‐on‐Stilts Microrobots for Transport and Delivery of Hydrophobic Cargo

open access: yesAdvanced Materials Interfaces, EarlyView.
Iron oxide nanoparticles and oil droplets in external magnetic fields form “drops‐on‐stilts” microrobots that transport hydrophobic cargo. Tunable nanoparticle–droplet interactions generate stilt‐like structures. Field rotation enables walking, obstacle navigation, and collective motion.

Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing

open access: yesAdvanced Materials Technologies, EarlyView.
Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the

ORNITHOPUS PERPUSILLUS L. (Leguminosae - Papilionoideae) IN LITHUANIA

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2006
Common birdsfoot serradella (Ornithopus perpusillus L.) was first reported in Lithuania in 1898, from a single site, Klaipeda harbor. In 2000 the species was found on the Curonian Spit near Nida, and in two more places almost in the centre of the country.
