Data‐Driven Modeling of Composition–Processing–Microstructure Relations for Recycled Aluminum Cast Alloys

open access: yesAdvanced Science, EarlyView.
Interpretable machine learning reveals how composition and processing govern the formation and microstructural burden of Fe‐rich intermetallic compounds in recycled Al–Si–Fe–Mn alloys. By separating morphology selection from morphology‐conditioned burden partitioning, this framework shows that identical Fe contents can yield different intermetallic ...

Plaid‐Like Spin Splitting and Chirality of Magnon Bands in Antiferromagnetic MnTe2

open access: yesAdvanced Science, EarlyView.
Helicity‐ and angle‐resolved Raman spectroscopy reveals chiral magnons in the non‐coplanar antiferromagnet MnTe 2. Combined with first‐principles calculations and spin‐wave theory, the results establish its altermagnetic character through circular Raman dichroism, reduced rotational symmetry, and a distinctive plaid‐like momentum‐space magnon spin ...

Review on the impact of elevated CO2concentrations on fruit species in the face of climate change

open access: yesCiencia y Tecnología Agropecuaria, 2022
Since the industrial revolution, anthropogenic activities have increased atmospheric CO2concentration—one of the major causes of global warming—with a 600 to 700 ppm prediction by the end of this century.

A numerical wave-maker for internal solitary waves with timely updated mass source/sink terms

open access: yes, 2017
On the basis of the two-dimensional Navier-Stokes equations, a new numerical method is proposed to generate internal solitary waves (ISWs) of expected parameters by adding a source term above the interface and a sink term below the interface into the ...

Ultrahigh Interfacial Thermal Conductance across GaN/BAs Interfaces via Atomic‐Level Engineering

open access: yesAdvanced Science, EarlyView.
The integration of gallium nitride (GaN) with ultrahigh‐thermal‐conductivity boron arsenide (BAs) substrates represents a promising pathway for developing next‐generation high‐power devices. The heat dissipation capability of such integrated systems is fundamentally governed by thermal transport across GaN/BAs interfaces, and buffer layers such as ...

Carbon sequestration by afforestation and revegetation as a means of limiting net-CO2 emissions in Iceland. COST E21 Workshop. Contribution of forests and forestry to mitigate greenhouse effects. Joensuu (Finland). 28-30 Sep 2000 [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2000
Iceland has lost about 95/ of its woodlands and 50/ of its vegetative cover during the 1,100 years of human settlement. Efforts to reclaim lost woodlands and herbaceous ecosystems have been continuing since the early 20th century.

Re‐Thinking Electronic Circuit Design Through Emerging Reconfigurable Field Effect Transistors

open access: yesAdvanced Science, EarlyView.
Graphical illustration of reconfigurable field effect transistor (RFET) operation modes, including n‐type, p‐type, and ambipolar transport, as well as their areas of application discussed in this review: digital circuit design, analog circuit design, post‐Shannon computing, and sensing. ABSTRACT Reconfigurable field‐effect transistors, short RFETs, are

Possibilities for carbon sequestration by the forestry sector in Hungary. COST E21 Workshop. Contribution of forests and forestry to mitigate greenhouse effects. Joensuu (Finland). 28-30 Sep 2000 [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2000
In Hungary, gross emissions of carbon amount to some 17.6 millions t C per year. Forestry, the only sector which can offset emissions, seems to be a net sink of 1.6 Mt C per year.

Core and π‐Bridge Engineering to Deconstruct Y6‐Series into Modular Non‐Fused Acceptors: DFT‐Guided Structure‐Property Map for Organic Solar Cells

open access: yesAdvanced Electronic Materials, EarlyView.
The rigid fused backbone of Y6‐series acceptors is deconstructed into a modular, non‐fused A‐π‐A′‐π‐A architecture. Comprehensive quantum chemical simulations reveal that strategic core and π‐bridge engineering preserves strong near‐infrared light‐harvesting and enhances intramolecular charge‐transfer character.

The Swiss carbon balance: methods, state of reporting and research perspectives. COST E21 Workshop. Contribution of forests and forestry to mitigate greenhouse effects. Joensuu (Finland). 28-30 Sep 2000. [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2000
For the 1990-1998 period, Switzerland reported an annual sink strength of Swiss forests of 4500-6000 Gg CO2. In its latest submission in 2000, newly available national forest inventory (NFI) data were used to refine earlier estimates.
