From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

Advanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Optimization of the Production of Rubber Compounds Using Mathematical Models

Advanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Preparation of Ordered Anodic Porous Alumina Films with a Sub-millimeter-scale Thickness by Anodization of Al in Oxalic Acid Containing a Small Amount of Sulfuric Acid

Electrochemistry
It was found that when an Al substrate was anodized in 0.3 M oxalic acid containing 50 mM sulfuric acid, the growth rate of the anodic porous alumina film (APAF) formed was significantly higher than that formed in an electrolyte without sulfuric acid. In

Machine Learning‐Supported Analysis for Predicting and Visualizing Nonlinear Relationships Between Material Properties in Electroplated Chromium Layers

Advanced Engineering Materials, EarlyView.
This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Application and Properties of Low Alloying Sulfuric Acid Dew Point Corrosion-Resistant Steels

Teshugang, 2005
The sulfuric acid dew corrosion- resistant steels are low alloying steels for heat exchanging component. There are two kinds of sulfuric acid dew corrosion- resistant steel:(1)base alloy elements-0.2%～0.5%Cu-＞0.010S adding a small quantity P,Sn,As, Sb,Se,

Inversely modeling homogeneous H₂SO₄ − H₂O nucleation rate in exhaust-related conditions [PDF]

Atmospheric Chemistry and Physics, 2019
The homogeneous sulfuric acid–water nucleation rate in conditions related to vehicle exhaust was measured and modeled. The measurements were performed by evaporating sulfuric acid and water liquids and by diluting and cooling the sample vapor with a ...
