List of Minerals Approved by IMA (F)
This list includes those recognised minerals beginning with the letter F. The International Mineralogical Association is the international group that recognises new minerals and new mineral names, however minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date. This list contains a mixture of mineral names that have been approved since 1959 and those mineral names believed to still refer to valid mineral species (these are called "grandfathered" species). The list is divided into groups: The data was exported from mindat.org on 29 April 2005; updated up to 'IMA2018'. The minerals are sorted by name, followed by the structural group (rruff.info/ima and ima-cnmnc by mineralienatlas.de, mainly) or chemical class (mindat.org and basics), the year of publication (if it's before of an IMA approval procedure), the IMA approval and the Nickel–Strunz code. The first link is to mindat.org, the second link is to webmineral.com, and the third is to the Handbook of Mineralogy (Mineralogical Society of America).

Teacher Professional Development in STEM Education
The implementation of an integrated approach of STEM (Science, Technology, Engineering and Mathematics) education with real-life scenarios is crucial to motivate students to learn and to better prepare them for real-world problems, which is a big challenge for teachers. By an integrated approach of STEM education in class, it is considered tasks that preferably include content related to all four of the STEM subjects included in the acronym. In addition, at the elementary level (e.g., primary school), it is recommended that tasks are introduced to students guided by the teacher in order to be adequate to their age. In this regard, teachers need to create a guided discovery environment to promote students’ learning in STEM subjects. Therefore, teachers need to participate in effective in-service professional development programmes to gain knowledge and skills to be able to develop this approach.

Fish Hooks Effect Living Aquatic Resources
The fish hook is a commonly known tool used in recreational fishing, which is one of the forms of active, specialised tourism. As a component of a fishing rod, the hook is intended to be anchored into the mouth of a fish and hold the fish on the end of the line while landing it. In the context of the protection of living aquatic resources and Catch-and-Release (C&R) fishing, its role and significance are becoming broader. In addition to the impact of the hook type on fishing efficiency, including the Catch Per Unit Effort (CPUE), the importance of hook selection in terms of minimising the resulting damage to the tissues of caught and released fish is increasing.

Circular Fashion Analysis
The 2030 Agenda for Sustainable Development adopted by all United Nations Member States in 2015 provides a catalogue of 17 Sustainable Development Goals (SDG). In this context, Circular fashion stands out as one of the sectors where commitment to the SDGs is most needed, given its global nature and its significant growth in terms of consumption. Moreover, it is not possible to assert that society, in general, is aware of the importance of the principles that guide circularity, both in terms of awareness and attitudes.

Plastic Pollution
Plastic is a word that initially meant “material that can be easily shaped, formed, molded by providing heat and pressure”. It only recently became a name for a category of materials called synthetic polymers. The polymer means “of many parts” and is a long chain of repeating smaller or larger molecules (monomers) bonded in subunits. Generally, natural polymers and synthetic polymers are used for making plastics. Synthetic polymers differ from natural polymers (such as silk, cellulose, muscle fiber, rubber, hair, and DNA). They are manufactured using raw materials such as oil, coal, and natural gas. There are two other types of plastics that do not fall into the above category of materials (natural or synthetic) and are known as biodegradable plastics and bioplastic materials. Biodegradable plastic is made from petroleum- or biomass-based resources. Bioplastic products are manufactured using biomass-based materials only. Both plastic materials are substitutes for synthetic plastic.

Two phytochrome A Types in Plants
The phytochrome (phy) system of plants with the main phyA and phyB controls their development beginning from seed germination to fruiting and senescence. The regulation reactions are categorized into three modes—the very low and low fluence responses (VLFR and LFR) and the high irradiance responses (HIR). The phyA is unique among the other phytochromes; it is major in etiolated seedlings and light-labile, and mediates all the three photoresponse modes. The phyB is light-stable, dominates in deetiolated plants, and performs the LFR. The phyA is itself heterogeneous which may explain its functional complexity. It comprises two native types, phyA′ and phyA″, the products of post-translational modification of the molecule at the N-terminus, possibly, via serine phosphorylation. This alters chromophore-apoprotein interactions resulting in the different photochemical, phenomenological, and functional properties of the two phyA pools. The phyA′ is major, water-soluble, and light-labile; the phyA″ is minor, amphiphilic, and relatively light-stable. The phyA′ mediates the VLFR whereas the water-soluble fraction of phyA″ is responsible for the HIR and LFR, the processes taking place in the nucleus. The membrane- (protein-) associated fraction of phyA” is likely to participate in the cytoplasmic photoregulation processes. The phyA pools' functions—their mode, intensity and sign—depend on plant's species, genotype and organ/tissue. The evidence of the existence of the two distinct phyA types in a plant, and their physicochemical properties and their role in the phyA functioning are discussed.

Land Take and Value Capture
Land use efficiency is a highly debated issue at an international level as several aspects can contribute to defining the concept of “efficiency”. However, if the term is contextualized in the field of urban development, this is closely linked to the concept of “public value”. The terms “land take” and “public value capture” (or often “land value capture”) as well as their use in different contexts have been discussed by scholars in the scientific literature in recent years. Marquard et al. (2020) argued towards bridging both notions of land consumption and LT. They proposed ways of addressing current ambiguities and suggested prioritizing the term “land take” in the EU context. Thus, the conceptual clarity around land consumption and LT has enhanced and a precondition for solidly informing respective policies and decisions provided. Barbosa et al. (2016) concluded that the implementation of the 2020 land take milestone will foster more efficient use of land and minimize negative impacts on non-artificial land uses. Colsaet et al. (2018) provided a systematic review on drivers of LT and urban land expansion. In this regard, they summarized the causal relationships between land take and different explanatory factors.Scholars concluded that “the effect of many factors however remains relatively undocumented or controversial in the reviewed literature, including widely used policy instruments”. Hendricks (2020) emphasized “public value capture” as one of the key factors of responsible land management and that smart instruments are needed for a successful implementation. He also characterized PVC as an essential phenomenon to improve the refinancing of public infrastructure and keep the necessary budget for other important duties such as social care.

Principles of pH-Responsive Drug Delivery
The paradigm of drug carriers’ usage to overcome the non-specific distribution of therapeutic agents in the body, including chemotherapeutic substances that exert severe toxic stress on healthy tissues, has been actively developed. One of the main pillars of this paradigm is the increased or even selective accumulation of drug delivery systems (DDSs) carrying therapeutic agents in tumor interstitium harnessing the differences between normal and cancer tissues properties. Thus, structural features of tumors, such as hypervascularization, vascular pathologies, and impaired functionality of lymphatic drainage, can be utilized to differentiate tumors from healthy tissues and selectively accumulate drug carriers. In particular, tumor-surrounding vessels are characterized by defects in the endothelial layer lining the blood vessel wall, represented by wide fenestrations (up to several microns) and other features that lead to an increase in the permeability of this barrier for small objects, making the effective extravasation of nanosized carriers from the bloodstream to tumor interstitium possible. Methods of selective therapy via the systemic administration of therapeutic agents based on increased permeability of the tumor vessels’ wall, known under the general name of the EPR effect, have become widespread and have inspired the creation of a large number of vehicles proposed for the delivery of chemotherapeutic agents. In summary, the EPR effect implies the extravasation of nanosized drug carriers through endothelial fenestra and their retention in the interstitial volume of the tumor due to dysfunctional lymphatic drainage.

Laser Polishing in Additively Manufactured Metals Post Processing
The poor surface roughness associated with additively manufactured parts can influence the surface integrity and geometric tolerances of produced components. In response to this issue, laser polishing (LP) has emerged as a potential technique for improving the surface finish and producing parts with enhanced properties. Many studies have been conducted to investigate the effect of LP on parts produced using additive manufacturing. The results showed that applying such a unique treatment can significantly enhance the overall performance of the part. In LP processes, the surface of the part is re-melted by the laser, resulting in smaller peaks and shallower valleys, which enable the development of smoother surfaces with the help of gravity and surface tension. Precise selection of laser parameters is essential to achieve optimal enhancement in the surface finish, microstructure, and mechanical properties of the treated parts.
