(American Chemical Society, 2020-03)The physicochemical properties and the synthesis of four α-pinene oxidation products, terebic acid, 3-methyl-1,2,3-butanetricarboxylic acid (MBTCA), diaterpenylic acid acetate (DTAA), and pinanediol, are presented in this ... -
Physicochemical Properties Predict Retention of Antibiotics in Water-in-Oil Droplets
(American Chemical Society, 2023-01-09)Water-in-oil droplet microfluidics promises capacity for high-throughput single-cell antimicrobial susceptibility assays and investigation of drug resistance mechanisms. Every droplet must serve as an isolated environment ... -
Point-of-care testing for C-reactive protein in a sequential microfluidic device
(Elsevier, 2023)Point-of-care testing (POCT) devices are currently available for the detection of various important diseases owing to their easy-to-use, portable, and user-friendly nature. However, the multistep regent manipulation still ... -
Pursuing the Complete OFF State in Photoswitchable Catalysis
(ACS Publications, 2023-11-28)Practically, all photoswitchable catalysts exhibit residual activity in the OFF state. Herein, we present a ruthenium initiator with a built-in photoswitch whose metathetical performance is completely shut off by light. ... -
Reaction Kinetics of Green Leaf Volatiles with Sulfate, Hydroxyl, and Nitrate Radicals in Tropospheric Aqueous Phase
(American Chemical Society, 2021-09-28)Green plants exposed to abiotic or biotic stress release C-5 and C-6 unsaturated oxygenated hydrocarbons called Green Leaf Volatiles (GLVs). GLVs partition into tropospheric waters and react to form secondary organic ... -
Redox behaviour of Cu-Aβ(4-16) complexes related to Alzheimer's Disease
(2024)The development of Alzheimer’s Disease (AD) has been linked to abnormal quantities of β-amyloid peptides in the brain. The majority of studies have focussed on Aβ(1-40/42) amyloids and their Cu(II)-Aβ(1-40/42) complexes ... -
Revealing the Variation of Photodetectivity in MAPbI3 and MAPb(I0.88Br0.12)3 Single Crystal Based Photodetectors Under Electrical Poling-Induced Polarization
(ACS Publications, 2022-07-28)The use of electrical poling to induce polarization potential has been found to increase the photocurrent (Ilight) in hybrid perovskite-based devices; however, the origin of this process has not been fully understood. ... -
Scaling equation for viscosity of polydimethylsiloxane in ethyl acetate: From dilute to concentrated solutions
(Elsevier, 2020)Rheology of polymer solutions suffers from lack of universal model of viscosity applicable across wide range of concentrations. Here we build such a model on the basis of measured viscosity of polydimethylosiloxane (PDMS) ... -
Scaling of submicrometric Turing patterns in concentrated growing systems
(American Physical Society, 2018-09-18)The wavelength of a periodic spatial structure of Turing type is an intrinsic property of the considered reaction-diffusion dynamics and we address the question of its control at the microscopic scale for given dynamical ... -
Scouting for strong light–matter coupling signatures in Raman spectra
