Bioinspired Design of Heterogenous Single‐Atomic‐Site Catalysts for Electrocatalysis and Photocatalysis

open access: yesAdvanced Materials, EarlyView.
This review gives a summary on the representative bioinspired single‐atomic‐site catalysts (SACs) and their applications in heterogeneous electrocatalysis and photocatalysis. The fundamentals of bioinspired design strategies are systematically discussed in the context of the first shell coordination, the second/long‐range coordination, and the outer ...

Rock Identification [PDF]

open access: yes
This hands-on activity covers the basics of rock identification. After a brief discussion of the terms 'rock' and 'mineral', students will study the characteristics and classifications of the three major rock groups (igneous, metamorphic, and sedimentary)

Artesunate Nanoplatform Targets the Serine–MAPK Axis in Cancer‐Associated Fibroblasts to Reverse Photothermal Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Materials, EarlyView.
The artesunate nanoplatform selectively targets ECM CAF, functioning as a GTPase inhibitor through disruption of intracellular serine homeostasis. This metabolic intervention effectively suppresses MAPK cascade activity, which consequently inhibits PTT‐induced CAF to ECM CAF differentiation.

Fossil biomass preserved as graphitic carbon in a late paleoproterozoic banded iron formation metamorphosed at more than 550°C [PDF]

open access: yes, 2019
Metamorphism is thought to destroy microfossils, partly through devolatilization and graphitization of biogenic organic matter. However, the extent to which there is a loss of molecular, elemental and isotope signatures from biomass during high ...

INVESTIGATING AN INNOVATIVE MODEL FOR DIMENSIONAL SEDIMENTARY ROCKS CHARACTERIZATION USING ACOUSTIC FREQUENCIES ANALYSIS DURING DRILLING

open access: yesRudarsko-geološko-naftni Zbornik, 2018
Determining geomechanical characteristics of rocks plays a significant role in all consequent designing stages of geosciences. On the other hand, drilling is one of the considerable operations in primer phases of extracting rocks.

Fluoroether Design Enables High‐Voltage All‐Solid‐State Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
A durable high‐voltage all‐solid‐state electrolyte is developed by incorporating a novel organic/inorganic hybrid porous component with a fluoroether design. Due to the weakened Li+ coordination structure, the proposed high‐voltage SSE exhibits durable antioxidation.
