IN THE CURRENT CONTEXT, WHERE SUSTAINABLE DEVELOPMENT HAS BECOME A GLOBAL IMPERATIVE, THE SEARCH FOR BIO-BASED MATERIALS PRESENTS UNIQUE CHALLENGES AND OPPORTUNITIES. THIS PERSPECTIVE ARISES FROM THE NEED TO BALANCE SOCIAL, ECONOMIC, AND ENVIRONMENTAL IMPACT, THUS ENSURING THE LONG-TERM VIABILITY OF PROJECTS AND COMPANIES. MYCELIUM, AS A BIO-BASED MATERIAL, REPRESENTS AN INNOVATIVE ALTERNATIVE FOR SUSTAINABLE PRODUCT DESIGN, OFFERING EXCEPTIONAL CHARACTERISTICS OF BIODEGRADABILITY AND LOW ENVIRONMENTAL IMPACT. BIOMIMICRY, A BIOLOGICALLY INSPIRED CREATIVE APPROACH THAT USES ANALOGIES WITH NATURAL SYSTEMS, IMITATES NATURE

LATTICE STRUCTURES EMERGED AS A REVOLUTIONARY CLASS OF MATERIALS WITH SIGNIFICANT APPLICATIONS IN AEROSPACE, BIOMEDICAL ENGINEERING, AND MECHANICAL DESIGN DUE TO THEIR EXCEPTIONAL STRENGTH-TO-WEIGHT RATIO, ENERGY ABSORPTION PROPERTIES, AND STRUCTURAL EFFICIENCY. THIS REVIEW SYSTEMATICALLY EXAMINES RECENT ADVANCEMENTS IN LATTICE STRUCTURES, WITH A FOCUS ON THEIR CLASSIFICATION, MECHANICAL BEHAVIOR, AND OPTIMIZATION METHODOLOGIES. STRESS DISTRIBUTION, DEFORMATION CAPACITY, ENERGY ABSORPTION, AND COMPUTATIONAL MODELING CHALLENGES ARE CRITICALLY ANALYZED, HIGHLIGHTING THE IMPACT OF MANUFACTURING DEFECTS ON STRUCTURAL INTEGRITY. THE REVIEW EXPLORES THE LATEST PROGRESS IN HYBRID ADDITIVE MANUFACTURING, HIERARCHICAL LATTICE STRUCTURES, MODELING AND SIMULATION, AND SMART ADAPTIVE MATERIALS, EMPHASIZING THEIR POTENTIAL FOR SELF-HEALING AND REAL-TIME MONITORING APPLICATIONS. FURTHERMORE, KEY RESEARCH GAPS ARE IDENTIFIED, INCLUDING THE NEED FOR IMPROVED PREDICTIVE COMPUTATIONAL MODELS USING ARTIFICIAL INTELLIGENCE, SCALABLE MANUFACTURING TECHNIQUES, AND MULTI-FUNCTIONAL LATTICE SYSTEMS INTEGRATING THERMAL, ACOUSTIC, AND IMPACT RESISTANCE PROPERTIES. FUTURE DIRECTIONS EMPHASIZE COST-EFFECTIVE MATERIAL DEVELOPMENT, SUSTAINABILITY CONSIDERATIONS, AND ENHANCED EXPERIMENTAL VALIDATION ACROSS MULTIPLE LENGTH SCALES. THIS WORK PROVIDES A COMPREHENSIVE FOUNDATION FOR FUTURE RESEARCH AIMED AT OPTIMIZING BIOMIMETIC LATTICE STRUCTURES FOR ENHANCED MECHANICAL PERFORMANCE, SCALABILITY, AND INDUSTRIAL APPLICABILITY.

JUNTO A LA APARICIÓN DE LA PRESENTE EDICIÓN, LA REVISTA MADERAS-CIENCIA Y TECNOLOGÍA, CUMPLE EL DÉCIMO ANIVERSARIO DE SU SELECCIÓN EN SCIELO-CHILE. ESTE HITO DEL AÑO 2005, MARCÓ NOTABLEMENTE LA NE-CESIDAD DE UN CAMBIO EN LA GESTIÓN DE MANUSCRITOS Y DE PROFESIONALIZACIÓN DE LA PRODUCCIÓN EDITORIAL DE LA REVISTA. EL PRIMER CAMBIO FUE INCORPORAR ADEMÁS DE LA PRODUCCIÓN EN PAPEL IMPRESO A LA PUBLICACIÓN ONLINE EN LA COLECCIÓN SCIELO. ESTE AVANCE IMPLICÓ LA INCORPORACIÓN DE UN PROFESIONAL DEDICADO A LA PRODUCCIÓN EDITORIAL DE LA REVISTA PARA CUMPLIR CON LOS PROTOCOLOS Y REQUISITOS DE LA TECNOLOGÍA REQUERIDA POR SCIELO. LA DIGITALIZACIÓN DE LA REVISTA Y SU VITRINA EN SCIELO FAVORECIÓ EL ACCESO A AUTORES Y LECTORES DE LA REVISTA. RESULTANDO QUE INMEDIATAMENTE DESPUÉS, LA REVISTA FUERA SELECCIONADA E INCORPORADA A REDALYC Y SCOPUS. EN ADICIÓN, EL FLUJO DE MANUSCRITOS SOMETIDOS A LA REVISTA SE INCREMENTÓ EN UN 50% EN LOS DOS PRIMEROS AÑOS EN SCIELO, LA TASA DE RECHAZO TAMBIÉN SE DUPLICÓ Y LA PRODUCCIÓN EDITORIAL AUMENTO EN UN 33 %, PASANDO A PRODUCIR TRES NÚMEROS ANUALES DE MANERA REGULAR Y A TIEMPO CON UN INCREMENTO DE 60% EN ARTÍCULOS CIENTÍFICOS PUBLICADOS.

CUANDO EN JUNIO DEL AÑO 2001, NOS ENCOMENDARON LA MISIÓN DE DIRIGIR LA REVISTA MADERAS. CIENCIA Y TECNOLOGÍA (MCT), COMENZAMOS A IMAGINAR UNA REVISTA DE CARÁCTER CIENTÍFICO QUE CONTRIBUYERA A MOSTRAR A LA SOCIEDAD UNA VISIÓN ORIGINAL DEL CULTIVO DE LAS CIENCIAS DE LA MADERA.

MICROWAVE PRETREATMENT (MWP) HAS EMERGED AS A PROMISING STRATEGY TO ENHANCE THE PYROLYSIS OF LIGNOCELLULOSIC BIOMASS DUE TO ITS RAPID, VOLUMETRIC, AND SELECTIVE HEATING. BY DISRUPTING THE RECALCITRANT STRUCTURE OF CELLULOSE, HEMICELLULOSE, AND LIGNIN, MWP IMPROVES BIOMASS DECONSTRUCTION, INCREASES CARBOHYDRATE ACCESSIBILITY, AND ENHANCES YIELDS OF BIO-OIL, SYNGAS, AND BIOCHAR. WHEN COMBINED WITH COMPLEMENTARY PRETREATMENTS?SUCH AS ALKALI, ACID, HYDROTHERMAL, ULTRASONIC, OR IONIC-LIQUID METHODS?MWP FURTHER REDUCES ACTIVATION ENERGIES, FACILITATING MORE EFFICIENT SACCHARIFICATION AND THERMAL CONVERSION. THIS REVIEW SYSTEMATICALLY EVALUATES SCIENTIFIC PROGRESS IN THIS FIELD THROUGH BIBLIOMETRIC ANALYSIS, MAPPING RESEARCH TRENDS, EVOLUTION, AND COLLABORATIVE NETWORKS. KEY RESEARCH QUESTIONS ARE ADDRESSED REGARDING THE TECHNICAL ADVANTAGES OF MWP, THE PHYSICOCHEMICAL TRANSFORMATIONS INDUCED IN BIOMASS, AND ASSOCIATED ENVIRONMENTAL BENEFITS. FINDINGS INDICATE THAT MICROWAVE IRRADIATION PROMOTES HEMICELLULOSE DEPOLYMERIZATION, REDUCES CELLULOSE CRYSTALLINITY, AND WEAKENS LIGNIN?CARBOHYDRATE LINKAGES, WHICH FACILITATES SUBSEQUENT THERMAL DECOMPOSITION AND CONTRIBUTES TO IMPROVED PYROLYSIS EFFICIENCY AND PRODUCT QUALITY. FROM AN ENVIRONMENTAL PERSPECTIVE, MWP CONTRIBUTES TO ENERGY SAVINGS, MITIGATES GREENHOUSE GAS EMISSIONS, AND SUPPORTS THE INTEGRATION OF RENEWABLE ELECTRICITY IN BIOMASS CONVERSION.
