POTENTIAL OF NANOPARTICLES IN REFRIGERATION SYSTEM WITH NATURAL REFRIGERANT - A REVIEW

open access: yes
The performance of cooling systems can be enhanced by introducing nanoparticles into compressor oils and refrigerants in refrigeration systems. This enhancement is necessary to ensure energy conservation and environmental sustainability. Nanorefrigerants/nanolubricant have emerged as a prominent application in the area of refrigeration systems, aiming ...

Lyophilized Synthetic Platelets: In Vitro Characterization and in Vivo Evaluation in Mouse Thrombocytopenia Model

open access: yesAdvanced Science, EarlyView.
ABSTRACT Platelet transfusions to treat bleeding complications use donor‐derived platelets stored at room‐temperature, that have a shelf‐life of only 5–7 days due to bacterial contamination risks. Cold‐stored and freeze‐dried platelets are being investigated for extending shelf‐life, but these still have the inherent challenge of donor‐dependency.

Buried Unstrained Germanium Channels: A Lattice‐Matched Platform for Quantum Technology

open access: yesAdvanced Science, EarlyView.
ABSTRACT Strained germanium (ε$\varepsilon$‐Ge) and strained silicon (ε$\varepsilon$‐Si) buried quantum wells have enabled advanced spin‐qubit quantum processors. However, in the absence of suitable lattice‐matched substrates, ε$\varepsilon$‐Ge and ε$\varepsilon$‐Si are deposited on defective, metamorphic SiGe buffers, which may impact device ...

Energy, Exergy, and Environment Performance Evaluation of Cascade Refrigeration System with Natural Refrigerants

open access: yesHittite Journal of Science and Engineering, 2023
Cascade refrigeration systems are preferred in applications where low temperature cooling is required, such as in some special industrial and laboratory applications. Since, in these systems, the energy consumed by the compressors is less and the compressor outlet temperature is lower.

A Novel Approach Based on Acceptor–Donor–Acceptor Type Molecules Enhances the Therapeutic Efficacy and Safety of Photothermal Therapy for Osteosarcoma

open access: yesAdvanced Science, EarlyView.
Jin et al. developed IEICO‐F nanoparticles with enhanced photothermal conversion efficiency via optimized push‐pull effect. Under 808 nm laser, these nanoparticles effectively generated heat to kill osteosarcoma cells and exhibited significant tumor suppression in vivo. Therefore, this novel A‐D‐A type molecule‐based photothermal therapy strategy holds

The Possibility of Intermittent Water Spray Implementation in a Non-Porous Indirect Evaporative Cooler

open access: yesEnergies
Evaporative cooling is a sustainable and energy-efficient technology based on water evaporation to achieve cooling. It uses air (R-729) and water (R-718) as refrigerants, so its effect on global warming is limited.

Biosynthesis of Sciadonic Acid Derived from Gymnosperms with Anti‐Colitis Activity

open access: yesAdvanced Science, EarlyView.
This study establishes an efficient Yarrowia lipolytica platform for unusual sciadonic acid (SCA) production and assess the anti‐colitis efficacy in mice of SCA, supporting its potential as a novel therapeutic lipid. ABSTRACT Sciadonic acid (SCA), Δ5‐unsaturated fatty acid with anti‐inflammatory and lipid‐regulatory properties, is predominantly derived

Tumor‐Infiltrating mregDCs Restrain Anti‐Tumor Immunity in Early Relapse HCC

open access: yesAdvanced Science, EarlyView.
Tumor‐infiltrating mregDCs are regulated by the TNFR2‐non‐canonical NF‐κB axis, which is mediated by TNF‐α secreted by CD161+CD8+ T cells. These mregDCs recruit CD161+CD8+ T cells via the CCL20‐CCR6 axis, forming a positive feedback loop that enhances immunosuppression, promotes early recurrence of HCC, and further confirms TNFR2 as a key therapeutic ...
