“…Rob and coworkers recently presented and tested a design for a two chamber monolith reactor (compare Fig. 9), in which the redox system was coated on a honeycomb structure for advanced mass transport [82,83]. Two chambers are operated at different temperature levels.…”

a b s t r a c tThis paper provides a perspective on the technologies capable of converting solar energy, CO 2 and H 2 O into an easy to use fuel. The paper addresses bio-based approaches, but mainly focuses on (i) the combination of photovoltaic (PV) devices and electrocatalysis, (ii) single unit operation by photocatalytic conversion, and (iii) solar thermal conversion. Each option is described in a general manner, including a brief evaluation of the advantages and disadvantages. Also suggestions for future research endeavours are given. Based on the used literature data, for electrocatalytic and photocatalytic technologies, dramatic improvements should be made in material optimization, as well as reactor design and operation. Large efficiency gains are necessary to enable use of these technologies in practice. Solar thermal conversion is more mature, and requires specific optimization in processing, as will be discussed.

“…Special magnetic and electrical properties, high chemical, and mechanical hardness [1], in modern information technology, have made ferrite films significantly important while designing the electromagnetic devices including the memories [2], sensors [3], and microwaves [4]. In particular, spinel-type ferrites such as MFe 2 O 4 where M = Co, Ni are among the most important magnetic materials which have been previously preferred over the past half century [5,6].…”

Cobalt ferrite, CoFe 2 O 4 , nanocrystalline films were deposited using electrostatic spray method and explored in sustainable hydrogen production application. Reflection planes in X-ray diffraction pattern confirm CoFe 2 O 4 phase. The surface scanning microscopy photoimages reveal an agglomeration of closely-packed CoFe 2 O 4 nanoflakes. Concentrated solar-panel, a two-step water splitting process, measurement technique was preferred for measuring the hydrogen generation rate. For about 5 hr sustainable, 440 mL/hr, hydrogen production activity was achieved, confirming the efficient use of cobalt ferrite nanocrystallites film in hydrogen production application.

“…Ironoxide-based redox materials, capable to operate under a complete redox cycle, could take oxygen from water producing pure hydrogen at reasonably low temperatures (800 C) and could be regenerated at temperatures below 1300 C. Ceramic honeycombs capable of achieving temperatures in that range when heated by concentrated solar radiation were assembled in a dedicated solar receiver/reactor. The operating conditions of the solar reactor were optimized to achieve adjustable, uniform temperatures up to 1300 C throughout the honeycomb, making thus feasible the operation of the complete cycle by a single solar energy converter (Agrafiotis et al 2005). The water transport through ion-exchange membranes is caused by osmosis and by electroosmosis.…”

In the context of ▶ diafiltration, wash water is simply another term for diluent. This is the water used to replace impure solvent while retaining the desired product. A typical example might be the washing of a cell suspension prior to cell disruption to release an intracellular product.The typical way of doing this would be to subject the cell suspension to batch crossflow microfiltration while adding wash water at a rate that exactly balances the filtrate (▶ permeate) flow rate. Thus, the cells are retained, but the impure liquid in which the cells are suspended is gradually displaced by wash water.
