Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Designation of the Civil War in the Epistles, Addresses, and Speeches of Patriarch Tikhon and in the Materials and Diaries of the Members of the Local Council

open access: yesHistoria provinciae: журнал региональной истории
The article is devoted to the use of the denomination “civil war” in the church milieu in 1917–20. In the summer of 1917 the Holy Synod published an epistle about the “domestic fratricidal war,” which began in Russia according to the highest church ...

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

open access: yesAdvanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

The causes of civil war [PDF]

open access: yes
The dominant hypothesis in the literature that studies conflict is that poverty is the main cause of civil wars. The authors instead analyze the effect of institutions on civil war, controlling for income per capita.

A Reproducible and Scalable Process for High Yield Mesenchymal Stromal Cell Extracellular Vesicles Production

open access: yesAdvanced Materials Technologies, EarlyView.
Mesenchymal stem cell derived extracellular vesicles (MSC‐EVs) are a promising therapeutic tool for regenerative medicine. However, the field lacks a reproducible high‐yield production method to answer the quantities needed for clinical translation.

The Economics of US Civil War Conscription [PDF]

open access: yes
The US government had limited power during the Civil War, including an inability to tax income. Similar to conscription plans considered in the War of 1812, Civil War conscription was not intended to compel service, but was a second-best plan to shift ...

Parallel Electrical Integration of Photo Bio Electrochemical Systems (photo‐BESs): Performance Gains and Load Dependency

open access: yesAdvanced Materials Technologies, EarlyView.
Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.

Impact of long-term civil disorders and wars on the trajectory of HIV epidemics in sub-Saharan Africa

open access: yesSAHARA-J, 2004
From the mid-1970s, seven countries in sub-Saharan Africa have experienced civil disorders and wars lasting for at least 10 years. In two — Sierra Leone during 1991–2002, and Somalia from 1988 and continuing — adult HIV prevalence remained below 1%.

Testing and Simulation of Multilayer Polyvinylidene Fluoride‐Based Piezoelectric Energy Harvester Devices

open access: yesAdvanced Materials Technologies, EarlyView.
The study considers the use of polymer/dielectric‐based multilayers piezoelectric Energy Harvesters (EH) to produce an output voltage and current, by exploiting the mechanical energy provided by human organs movements. In particular, the heart motion is considered from the kinematic viewpoint, and a multiphysics theoretical model is developed to assess
