Impact of quantum-chemical metrics on the machine learning prediction of electron density

Machine learning (ML) algorithms have undergone an explosive development impacting every aspect of computational chemistry. To obtain reliable predictions, one needs to maintain a proper balance between the black-box nature of ML frameworks and the physics ...

Fiber-Tip Polymer Microcantilever for Fast and Highly Sensitive Hydrogen Measurement

Giovanni Dietler, Sandor Kasas, Jiangtao Zhou, Leonardo Venturelli, Yiping Wang, Chaohui Li, Meng Zhu, Cong Xiong

Hydrogen as an antioxidant gas has been widely used in the medical and biological fields for preventing cancer or treating inflammation. However, controlling the hydrogen concentration is crucial for practical use due to its explosive property when its vol ...

Predictive Models for Thermal Stability and Explosive Properties of Chemicals from Molecular Structure

Nadia Baati

Industrial chemical processes may involve thermal risks as most of the reactions performed are exothermic, the chemicals used are often thermally unstable, and the operating conditions are set to induce high conversion and throughput. Besides the reactive ...

MEMS-based Porous Silicon Preconcentrators Filled with Carbopack-B for Explosives Detection

Nico de Rooij, Danick Briand, El Hadji Malick Camara

In this paper we report the detection of explosive compounds using a miniaturized gas preconcentrator (μGP) made of porous silicon (PS) filled in with Carbopack B as an adsorbent material. The μGP includes also a platinum heater patterned at the backside a ...

Chalcopyrite thin-film solar cells by industry-compatible ink-based process

Cyril Cayron

We developed a new industry-compatible ink-based process to produce efficient chalcopyrite CuIn1-xGaxSe2 thin-film solar cells. Metallic In and Ga nanoparticles were produced by purely physical methods, using a low-cost and non-explosive solvent. The solve ...

Commercial Systems for the Direct Detection of Explosives (for Explosive Ordnance Disposal Tasks)

Claudio Bruschini

There are a number of Explosive Ordnance Disposal (EOD) tasks in which it is necessary to discriminate and identify UneXploded Ordnance (UXO) already detected by other means. What we seek is the capacity to characterize in a non-destructive way the munitio ...

The initiation of a calcium signal in Xenopus oocytes

Carl Petersen

Application of acetylcholine to Xenopus oocytes evoked increases in the cytosolic free calcium ion concentration ([Ca2+]i) after latencies of up to several seconds depending on the agonist dose. Higher acetylcholine concentrations evoked responses with lar ...
