Carbon capture technologies have been recognized as a potential alternative to alleviate global warming. and storage (CCS) is preferred over carbon conversion utilization (CCU) due its lower operating costs higher CO2 reduction capability. Nevertheless, has the be more economical if value-added products are produced. This highlights importance of assessing routes alternatives in management. rev...

Cellulose has been efficiently isolated from almond shell (AS) of a soft-shell Carmel variety by two-step NaClO2 oxidation-KOH alkali protocol at over 35 % yield, then optimally TEMPO-oxidized and blended to yield 92 averagely 1.2 nm high (H), 5.2 wide (W), 1.4 µm long (L) cellulose nanofibers (CNFs) with 58.6 crystallinity 1.3 mmole/g charge. With uniquely 1167 L/H aspect ratio 4.3 W/H lateral...

According to questionnaire studies, speech is the most annoying sound source in open-plan offices [1]. The most distracting speech comes from the nearest workstations. Therefore, speech privacy between workstations should be as high as possible, that is, the speech transmission index, STI, should be low. This presupposes that the speech is properly attenuated, e.g. using absorbents, screens, an...

Abstract A thermodynamic model is developed for a forward osmosis (FO) absorption heat pump capable of purifying graywater and providing year-round space conditioning with low-temperature as the primary energy input. The applied to 16 potential absorbents, six are selected parametric studies on desorber temperature, absorber condenser sink temperature determine effects ratio (defined total usef...
