A facile approach to prepare silica hybrid, spin-crossover water-soluble nanoparticles as potential candidates for thermally responsive MRI agents
(2021)A reverse micelle method was used for the synthesis of water-soluble silica hybrid, spin-crossover (SCO) nanoparticles (NPs). MRI experiments provided temperature dependentT2 values, indicating their potential use as smart ... -
Impact of sewage sludge, nanoparticles, and clay minerals addition on cucumber growth, phosphorus uptake, soil phosphorus status, and potential risk of phosphorus loss
(2021)There is little information about the impact of sewage sludge, nanoparticles, and clay minerals on cucumber (Cucumis sativus L.) growth and phosphorus content in different plant parts. In this study we treated a soil with ... -
Information content in nuclear medicine imaging
(2019)The aim of the present study was to investigate the information content of positron emission tomography (PET) images. We used the GATE Monte Carlo package (GEANT4 application for tomographic emission) and reconstructed ... -
Magnetic nanoparticles in medical diagnostic applications: Synthesis, characterization and proteins conjugation
(2016)Background: Magnetic nanoparticles (NPs) used in biomedical applications should be discrete with small particle sizes, narrow size distribution and superparamagnetic. NPs can be tailored to target, through chemical bonds, ... -
Numerical analysis of the seismic response of sand passively stabilized against liquefaction
(2015)Passive stabilization is a new technique for mitigating the risk of seismic liquefaction in the non-cohesive foundation soil of existing structures. It consists of the low pressure injection (in the soil pores) of colloidal ... -
Permeation potential of colloidal silica for passive stabilization of liquefiable soils
(2015)Passive stabilization is a new ground improvement technique against liquefaction. It consists of the low pressure injection of colloidal silica in the pores of a liquefiable soil. After well-controlled time, colloidal ... -
Phenomenological simulation of the seismic response of ground stabilized with colloidal silica
(2014)Passive stabilization is a novel technique for mitigating the risk of seismic liquefaction in the non-cohesive foundation soil of existing structures. It entails the low-gradient injection of colloidal silica in the soil ... -
Rheological properties of colloidal silica as a means for designing passive stabilization of liquefiable soils
(2015)Passive stabilization is a novel ground improvement technique for mitigating liquefaction at developed sites. It is based on the low-gradient (low pressure) injection in the soil pores of colloidal silica, an aqueous ... -
Rheological properties of colloidal silica grout for passive stabilization against liquefaction
(2018)Passive (site) stabilization is a novel technique for the mitigation of seismic liquefaction which uses low-pressure injection of colloidal silica in the pores of a granular soil. The applicability of colloidal silica as ... -
Sustainable applications of rice feedstock in agro-environmental and construction sectors: A global perspective
(2022)Rice is second only to maize among the world's most important cereal crops, with a global harvested area of approximately 158 million hectares and an annual production of more than 700 million tonnes as paddy rice. At this ... -
Synthesis of nitrogen-doped mesoporous carbon nanosheets for oxygen reduction electrocatalytic activity enhancement in acid and alkaline media
(2019)In the present work, nitrogen-doped mesoporous carbon nanosheets (NMCNs) are prepared and extensively investigated for the oxygen reduction reaction. Initially, by using dual templates, viz. graphene oxide and a cationic ...
