Microbial Contribution to Soiling and Its Impact on Photovoltaic Module Soiling in Arid Zones of the Atacama Desert

Advanced Sustainable Systems, EarlyView.
Microorganisms colonizing photovoltaic surfaces in the Atacama desert form biofilms that enhance particle adhesion and reduce energy yield. This study identifies UV‐resistant bacteria and carotenoid‐producing strains that interfere with PV performance.

The Crixas Gold Deposit, Brazil: Metamorphism, Metasomatism And Gold Mineralization [PDF]

, 1987
The Crixas Gold Deposit is located in Crixas Greenstone Belt, Goias. The area is underlain by metamorphosed Archean rocks consisting of a basal unit of ultramafic rocks. This is overlain by tholeiitic metabasalts which are in turn overlain by meta-pelitic rocks.;Structural hanging wall to footwall lithologic sequence of the deposit consists of ...

Modulating Integrin and Growth Factor Signaling With Peptides: Strategies to Synergistically Enhance Bone Tissue Regeneration

Advanced Science, EarlyView.
It has been demonstrated that, in the bone extracellular matrix (ECM), integrins and growth factor receptors (GFRs) engage in synergistic signaling to guide bone healing and regeneration. This review provides a comprehensive overview of current strategies using ECM‐derived peptides to recreate the cellular microenvironment and harness synergistic ...

Distinct Immunomodulatory Strategies Guide Mesenchymal Stromal/Stem Cell‐Mediated Bone Regeneration

Advanced Science, EarlyView.
Bone regeneration by mesenchymal stem cells is strongly influenced by immune signals. This study shows that priming stem cells with regulatory immune cells or an inflammation‐resolving lipid molecule enhances bone formation through distinct immune pathways.

Sensory Nerve‐Derived CGRP Controls Osteoclastogenesis by Limiting Macrophage Bioenergetics in Bone Repair

Advanced Science, EarlyView.
Sensory nerves help bones heal. This study shows that the neuropeptide CGRP, released from sensory nerves, slows down macrophage energy production, preventing excessive bone breakdown. By revealing this nerve–immune–metabolism connection, the work provides new insight into how the body balances bone repair and opens doors to targeted treatments ...
