Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Whole Body Microwave Irradiation for Improved Dacarbazine Therapeutical Action in Cutaneous Melanoma Mouse Model

Radiology Research and Practice, 2013
A cutaneous melanoma mouse model was used to test the efficacy of a new therapeutical approach that uses low doses of cytostatics in conjunction with mild whole body microwave exposure of 2.45 GHz in order to enhance cytostatics antitumoral effect ...

Direct measurement of radiation exposure dose to individual organs during diagnostic computed tomography examination

Scientific Reports, 2021
Ionizing radiation from Computed tomography (CT) examinations and the associated health risks are growing concerns. The purpose of this study was to directly measure individual organ doses during routine clinical CT scanning protocols and to evaluate how

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

Advanced Functional Materials, EarlyView.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

5,6,7,8-tetrahydroneopterin (NH4) Acts like an Endogenous Superoxide Dismutase

Pteridines, 1996
The protective effect of 5,6,7,8-tetrahydroneopterin (NH.) against radiation injury in mice was studied. (C57BL/6x A/J)F1 mice received whole body irradiation with a single fatal dose of 8.0 Gy X-ray.

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

Advanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Solution‐Processed Mn‐Doped 2d Perovskite Wavelength Shifters for Noble‐Liquid Photon Detection

Advanced Functional Materials, EarlyView.
Solution‐processed Mn2+‐doped PEA2PbBr4 two‐dimensional perovskite films are demonstrated as large‐area wavelength shifters for noble‐liquid photon detectors. Mn2+ incorporation introduces a broad emission band at ∼620 nm with a large Stokes shift, suppressing self‐absorption and matching SiPM sensitivity.

Amplifying radiation-induced anti-tumor immunity: the dual role of brachytherapy and low-dose total body irradiation

Frontiers in Immunology
BackgroundRadiotherapy can be a vaccine by triggering patients’ prophylactic tumor-specific immune responses. Brachytherapy has biological and physical benefits over external beam radiation.

[Methods of whole body irradiation].

Srpski arhiv za celokupno lekarstvo, 1995
Total body irritation, the essential method of pretreatment of a patient for bone marrow transplantation has not yet been a routine practice in our radiotherapy centres. Basic components of total body irradiation methods are reviewed, because they should be considered as a background for the very first decision in the choice of a method and details of ...
