Short-chain alcohols are a group of volatile organic compounds (VOCs) that are often found in workplaces and laboratories, as well as medical, pharmaceutical, and food industries. Real-time monitoring of alcohol vapors is essential because exposure to alc... see more

Quartz Crystal Microbalance (QCM) merupakan salah satu jenis resonator kuarsa yang memiliki membran sensitif terhadap gas. Pada sistem identifikasi gas menggunakan QCM, perubahan frekuensi dari sensor ini begitu cepat, sehingga untuk mendapatkan perubaha... see more

Dalam suatu sistem identifikasi gas menggunakan sensor Quartz Crystal Microbalance (QCM) diperlukan sebuah pencacah frekuensi yang digunakan untuk menghitung perubahan frekuensi dari sensor. Sistem ini digunakan untuk menghasilkan output berupa pe... see more

Polystyrene (PS) thin film with various concentration of mass (1%, 3%, and 5%) has been deposited onto Quartz Crystal Microbalance (QCM)  surface by a spin coating method. The purpose of this research is the improvement of Bovine Serum Albumin (BSA) ... see more

A new approach to study the chemical stability of electrodeposited lithium on a copper metal substrate via measurements with a fast impedance scanning electrochemical quartz crystal microbalance is presented. The corrosion of electrochemically deposited l... see more

This article covers a topic discussed in the master’s thesis (Basssi, 2012) on technological analysis of the quartz crystal, from the archaeological site Bibocas II in Jequitaí MG. Through the analysis of the axes in the natural crystal fac... see more

The current study presents an original chemical, elemental and mineralogical characterization of new quartz mineral deposits situated in Ios island, Cyclades, Aegean sea, Greece, via X-Ray Diffraction (XRD), Scanning Electron Microscopy with Energy Disper... see more

Fluorinated epoxy resins were synthesised and evaluated as sorbent coating materials for the detection of organophosphorus compounds using quartz piezoelectric crystal detector. These resins were prepared by reacting excess of epichlorohydrin with each of... see more

Seismic wave propagation in organized matter usually results in azimuthal variations of longitudinal waves (Pwaves), as well as the effect of birefringence in transversal waves (S-waves), which results in two orthogonal shear waves with contrasting veloci... see more
