Wood Carbon Sponge/SiO2 Aerogel Composites with Anisotropic Broadband Microwave Absorption, Elastic Resilience, and Thermal Insulation

open access: yesAdvanced Science, EarlyView.
Anisotropic wood carbon sponge/SiO2 aerogel composites are constructed, revealing a robust direction‐dependent permittivity ordering (tangential > radial > axial). The radial direction delivers an ultra‐broadband effective absorption bandwidth of 11.6 GHz at only 4.95 mm, while the tangential direction offers superior compressibility and thermal ...

Din colecțiile Muzeului Național al Banatului din Timișoara. I. Celturi izolate/singulare din Banatul Românesc.

open access: yesAnalele Banatului. Arheologie-Istorie, 2020
On this occasion we chose to publish some socketed axes, that were discovered in the Romanian Banat, but with- out an archaeological context, pieces that can be included in that broader category of “isolated/singular” objects.

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism

open access: yesAdvanced Science, EarlyView.
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

Real‐Time Monitoring of Mass and Mechanical Properties in Single Cells and Multicellular Spheroids

open access: yesAdvanced Science, EarlyView.
This study introduces photothermally actuated microcantilevers combined with optical microscopy to simultaneously measure morphology, mass, and mechanical properties of cellular systems in real‐time. The findings link cytoplasm‐dominated mechanical energy dissipation to the Q‐factor as a novel biophysical parameter.

Highly Stable and Non‐Volatile Optoelectronic Synapses for Sensing, Memory, and Computing Enabled by a Deep‐Potential Floating Gate

open access: yesAdvanced Science, EarlyView.
A deep‐potential metal floating gate integrates electrical programming, optical partial erasure, and synaptic weight modulation in a MoS2/h‐BN/Au transistor. The device provides a 97.6 V memory window, retention beyond 3000 s, endurance over 1600 cycles, and reproducible operation after 200 days of ambient storage.

The collapse of the Bronze Age civilization in the Mediterranean area 3,200 years ago: climate change, natural disasters, water scarcity, food production crisis and weakening social governance

open access: yesStudia Humanitatis
The Bronze Age (c. 3300 – c. 1200 BC) in the eastern Mediterranean area was a historical period characterized principally by the use of bronze tools and the development of complex urban societies, as well as the adoption of writing in some areas.

Mitochondrial Protection and Neural Repair via ROS‐Responsive Biomimetic Nanoparticles in Intracerebral Hemorrhage

open access: yesAdvanced Science, EarlyView.
A ROS‐responsive biomimetic nanoparticle platform co‐delivers DIDS and Mdivi‐1 to protect mitochondria and promote neural repair after intracerebral hemorrhage. By targeting LPAR1/VDAC1‐related mitochondrial dysfunction, the nanotherapy reduces oxidative injury, neuronal apoptosis, and blood‐brain barrier disruption, improving neurological recovery and
