Influence of a Standard Heat Treatment on the Microstructure and Properties of Inconel X‐750 Produced by Laser Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

Amerind ancestry, socioeconomic status and the genetics of type 2 diabetes in a Colombian population. [PDF]

open access: yesPLoS ONE, 2012
The "thrifty genotype" hypothesis proposes that the high prevalence of type 2 diabetes (T2D) in Native Americans and admixed Latin Americans has a genetic basis and reflects an evolutionary adaptation to a past low calorie/high exercise lifestyle ...

Multi‐Scaled Cellulosic Nanonetworks from Tunicates

open access: yesAdvanced Functional Materials, EarlyView.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–

Why are Latin Americans so Unhappy about Reforms? [PDF]

open access: yes
The objective of this paper is to use opinion polls to document Latin Americans` increasing discontent with reforms and to explore possible explanations for this trend. We test four possible explanations for the rejection of reforms. The first focuses on

Advancements in Understanding the Physicochemical Properties of Reticular Materials: An In Situ and Operando Spectroscopic Perspective

open access: yesAdvanced Materials, EarlyView.
This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

Life Cycle Assessment of Magnesium‐Impregnated Biochar Production and its Application for Nutrient Removal and Soil Improvement in Rice Cultivation

open access: yesAdvanced Sustainable Systems, EarlyView.
This study evaluates the environmental trade‐offs of different rice husk management strategies using a life cycle assessment (LCA) approach. It compares biochar production for water treatment and soil improvement with direct incineration for energy generation.

Non‐Invasive Diagnosis of Chronic Myocardial Infarction via Composite In‐Silico‐Human Data Learning

open access: yesAdvanced Science, EarlyView.
This study presents a non‐invasive machine learning model to identify infarct regions in the left ventricle using cardiac strain data. By combining rodent‐based simulated data with limited human data, the model achieves high accuracy in predicting infarct size and location without the need for gadolinium contrast agents, offering a promising ...
