We present a theoretical study of an experiment designed to detect radiation-pressure shot noise in an optomechanical system. Our model consists of a coherently driven optical cavity mode that is coupled to a mechanical oscillator. We examine the cross-correlation between two quadratures of the output field from the cavity. We determine under which circumstances radiation-pressure shot noise ca...

Membrane separation technologies have recently received much attention, from lab-scale studies to full-scale operations, in the forest industry. However, membrane fouling comprises a signifcant obstacle to their broad application. Thus, to ensure cost-effective operation of membrane separation processes, the improved elucidation of membrane fouling and establishment of e...

Microsystems become part of everyday life but their application is restricted by lack of strong and fast motors (actuators) converting energy into motion. For example, widespread internal combustion engines cannot be scaled down because combustion reactions are quenched in a small space. Here we present an actuator with the dimensions 100 × 100 × 5 μm(3) that is using internal combustion of hyd...

A novel tannic acid - ferric (TA-Fe) complex coating was applied to commercially available cellulose triacetate (CTA) forward osmosis (FO) membrane enhance performance. Notably, the coated attained a better water/salt selectivity than control and it had mild water permeability loss of about 13.6%. Consequently, when is operated in FO system, reverse salt flux smaller as compared uncoated membra...

Premix membrane emulsification (PME) is a pressure driven process of droplet breakup, caused by their motion through pores. The widely used for high-throughput production sized-controlled emulsion droplets and microparticles using low energy inputs. resultant size depends on numerous process, membrane, formulation factors such as flow velocity in pores, number extrusions, initial size, internal...
